The blue sky, green earth, fresh air, medieval style buildings, and pedestrians traveling around. Although they only live in a space surrounded by walls, they are enough to allow humans to live and reproduce with peace of mind. |[2][3][w][x]}

This is a world with giants, a mysterious and unknown world. At least Lu Yunfeng doesn’t know much about this world, because he only watched a few episodes of cartoons in his previous life, and then watched some discussion posts on animation online, and nothing else was left. The reason why he came to this world was because after experiencing many worlds, he suddenly wanted to see what was going on in this world that made humans perverted and desperate?

Ordinary people who have no martial arts or magic are fighting against giants, and they find it interesting no matter how they think about it.

As he experienced more worlds, Lu Yunfeng was too lazy to seal his own power, so he had already many worlds. Lu Yunfeng had always been wandering around in various worlds with all his strength. The dangerous world for others was very relaxed. With his current strength, of course, he refers to his strength in reality, which should be similar to that of Tathagata Buddha.

Although the attacking giant looks terrifying, it is only for ordinary people. For Lu Yunfeng, he can send those giants to hell in minutes, so for him, this world is a process of experience and exploration.

"Brother Lu!" A vital voice came from afar. Lu Yunfeng lay comfortably in the grass by the river, raised his hand and waved it.

"Brother Lu, I have learned the fighting skills you taught me." The person who came was two teenage children, one boy and one girl. The boy was so energetic, but the girl was a little indifferent and seemed to care about nothing.

"Have you learned so soon?" Lu Yunfeng turned his head and looked at the two children. Seeing the little boy's nose and face were swollen, he smiled slightly: "Mikasa has helped a lot!"

The little boy blushed and shouted, "Mikasa is just a training student, I work very hard."

"Okay! I get it." Lu Yunfeng sat up, stretched his waist, and said to the little boy: "Come here to attack me. Let me see how your fighting skills are?"

"Okay!" The little boy became very serious in an instant. He made a fighting posture and shook his upper body. His fist seemed to be swinged at any time to attract Lu Yunfeng's attention. Then the little boy flew out unexpectedly. Although he was young, he also made a howling sound of breaking through the air, which showed that the little boy was still quite strong.

Bang-

Lu Yunfeng easily grabbed the little boy's ankle and then flipped it up. The little boy suddenly lost his balance and fell to the ground with a wow sound: "It hurts so much..."

"Alan, is it okay?" The little girl named Mikasa rushed over and helped the little boy up.

"Allen, fighting skills alone are not enough. If you want to defeat your opponent, strength and speed are essential." Lu Yunfeng stood up, patted the grass blades on his body, and said, "It's like a giant outside the wall. If the giant's size is not that huge, with their slow movement speed, humans can destroy them at will, how could they be humiliated and locked in the wall for a hundred years?"

Alan, who was crying, forgot the pain and listened carefully to Lu Yunfeng's story. The girl named Mikasa was also listening silently.

"Alan, Mikasa, do you know the history of mankind?" Lu Yunfeng smiled and looked at the protagonist of the two giants.

"I don't know." Allen shook his head and said, "Those clergy say that man was created by God, and I don't know if that is the case?"

"Of course not." Lu Yunfeng shook his head: "How can there be such an illusory thing like God in the world? It's just something that some people have created for their own interests. If there is really a God in the world, why doesn't he appear to destroy giants and save humans? If God is omniscient and omnipotent, this is very simple for him!"

"Yes!" Allen nodded and said, "It turns out that there is no god in the world, that's all lie."

Lu Yunfeng nodded and said, "The so-called human beings are actually evolved among all living things after countless years of baptism. The ancestors of human beings are likely to be a kind of ape."

"Ape?" Alan and Mikasa showed shock.

"Yes." Lu Yunfeng nodded and smiled, "Actually, I saw it from the book."

"Book?" Allen asked excitedly, "Brother Lu, is it a book from the outside world?"

"You just need to know it in your heart, don't say it out." Lu Yunfeng smiled and shook his head: "Otherwise, if the nobles who have been blocking external information know about it, they will definitely arrest us in prison and enjoy torture."

"Hmph!" When talking about the nobles, Alan looked down on it: "Those pigs that only know how to eat, drink and have fun will sooner or later be eaten by giants."

"If they were eaten by giants, then ordinary people would probably have been eaten up long ago." Lu Yunfeng shook his head: "After all, there are people around them who are protected, and ordinary people can only rely on themselves."

Allen scratched his head: "Brother Lu, I don't really understand."

"It's okay, you're still young, you'll understand in the future." The big hand rubbed Alan's head. Lu Yunfeng turned his head and looked at the city wall that was as high as fifty meters, and sighed: "Although it is protected, what's the difference between this and the livestock in a pigpen that is locked in a chicken cage and a pigpen?"

"That's it!" Hearing Lu Yunfeng's words, Allen agreed very much: "Brother Lu, have you been outside? The world outside must be very exciting! When I grow up, I will also go outside to take a look."

"The outside world is wonderful, but the premise is that you have the ability to protect yourself." Lu Yunfeng retracted his gaze, looked at Alan and Mikasa with a worried look on his face, and smiled slightly: "The reason why chickens and ducks are locked in a cage is because they have no power to protect themselves. Once they leave the cage, they will be eaten by foxes and wolves outside. Nowadays, humans are chickens and ducks, and giants are foxes and wolves. If you want to run freely outside, you must first learn how to deal with the attacks of foxes and wolves, otherwise they will only become their food. Do you understand?"

Allen nodded vigorously and then said, "So Brother Lu and I learned fighting skills to make ourselves able to protect ourselves. In the future, I will join the Investigation Corps and then drive away the giants, so that humans can live freely in the outside world."

"Good volunteer." Lu Yunfeng smiled slightly: "But just saying it is useless. Moreover, humans are too weak to giants, not fast, and small in size. When they meet giants with bare hands, they will only die. So what humans can rely on is not power, but here." Lu Yunfeng pointed to his head.

"Head?" Allen asked a question mark: "Brother Lu wants me to hit the giant with his head?"

Lu Yunfeng and Mikasa both sweated coldly and expressed powerlessness to Alan's IQ.

"I mean to use my brain." Lu Yunfeng shook his head helplessly: "The reason why humans can survive is because compared to other creatures, humans can use tools, make tools, and use tools. It is like cannons guarding city walls and three-dimensional mobile devices used for soldiers' personal personalities. These are all made by humans' minds. If there were no such things, humans would have been eaten by giants long ago."

"So that's it." Allen scratched his head and said, "But I'm not good at inventing these things, Amin! Amin must do it. He is very smart and the smartest among the people I know."

"Amin Arnold!" Lu Yunfeng nodded: "That's indeed a smart child, and he may become a famous commander in human history in the future."

"Yes! Amin is really smart, okay!" Alun said vigorously: "In the future, Amin commands the battle, and I will kill those giants on the front line and save all mankind."

Lu Yunfeng chuckled: "It's useless to save all humanity by relying on you two." Lu Yunfeng smiled and shook his head, then looked at Mikasa and whispered: "If Mikasa kills the giant on the front line, I'll feel more at ease."

When Mikasa heard Lu Yunfeng's evaluation of Mikasa, Mikasa was stunned for a moment, then smiled and scratched her face, a little embarrassed, but Alan was quite unhappy: "As long as I train hard, I will definitely surpass Mikasa in the future."

"Well, your fighting spirit is indeed the highest I have ever seen. When others retreat, you can move forward bravely and maybe create miracles." Lu Yunfeng nodded.

"Is that true?" Allen didn't expect Lu Yunfeng to give him such a good evaluation, and he felt a little embarrassed for a moment: "Actually, it's not that powerful."

"No, you misunderstood." Lu Yunfeng shook his head and said, "Although you have the possibility of creating a miracle, the greater possibility is that you die earlier than anyone else and suffer worse than anyone else. Unless you are really lucky enough to be against the will of heaven, otherwise once you go to the battlefield to fight against the giants, you are likely to die first."

These words made Mikasa frown, and the look of her eyes looking at Alan was filled with a deep look of worry.

"Impossible! I won't die." Allen didn't believe Lu Yunfeng's judgment at all: "As long as I learn the fighting skills of warriors and learn how to use three-dimensional mobile devices, I will definitely not be killed by the giant."

"Maybe! Who knows!" Lu Yunfeng stretched and said, "Okay, it's almost noon, let's go! I'll treat you to a meal."

"Okay!" Hearing the word "eat", Alan's saliva was almost falling, and Mikasa also swallowed her saliva frequently, full of expectations for the meals at Lu Yunfeng's house.

Lu Yunfeng is an orphan in this world. He has lived here for three years. He lives in a very outer wooden house. He has surrounded a circle of fences and raised a lot of chickens and ducks. He also has a piece of land. He can be self-sufficient. Lu Yunfeng and Alan, Mikasa, met half a year ago. Two little guys were playing outside and accidentally ran to his house. At that time, Lu Yunfeng had just roasted a beggar chicken. The fragrance made Alan and Mikasa swallow frequently. Lu Yunfeng laughed and kept them eating beggar chicken together, and then chatted for a few more words. From then on, the two little guys came over from time to time to eat for free. Because Lu Yunfeng seemed to be very knowledgeable, Alan liked to listen to him telling stories related to the outside world. Gradually, the three became friends. Because Lu Yunfeng was ten years older than them, they were all called Lu Yunfeng and Brother Lu, and their relationship was like brothers and sisters.

Not long ago, because Allen was beaten up by a group of "little friends", Lu Yunfeng taught him a simple fighting technique. Then, after learning for a few days, Alan defeated them all in the face of the "little friends". This made Allen very excited and ran over to express his gratitude to Lu Yunfeng.

When he brought the two little guys home, Lu Yunfeng cut the fat chicken that he slaughtered early this morning into pieces and stir-fry it with chili. He washed some vegetables, ordered coal, and stewed it in the pot. A spicy hotpot chicken was done in this way.

"It's delicious, so delicious." Although it was so spicy that I was sweating profusely, Alan and Mikasa ate very happily. Lu Yunfeng also grilled some steamed bun slices and skewed them together for the two little guys to eat.

"Brother Lu, the rice you cook is so delicious, and this thing called steamed bun is very strange! It is not the same as the bread we eat." Allen said while gnawing on the steamed buns.

"The recipes are different. The taste is naturally different." Lu Yunfeng smiled slightly. He put a piece of chicken in Mikasa bowl and said, "You are growing up. You must eat full every meal, especially Mikasa. You are too thin. Eat more."

Mikasa looked at Lu Yunfeng and nodded: "Thank you, Brother Lu."

"Eat it!" Rubbing Mikasa's head, Lu Yunfeng smiled and ate a bite of the steamed bun, put the rinse dishes into a bowl and dipped them in some vinegar. He put them into his mouth to chew.

The two little guys were particularly satisfied with the meal. After that, Lu Yunfeng took the two little guys to the woods to pick up dry firewood. Lu Yunfeng also cut down a big tree with an axe. Under Alan's envious and admiring eyes, he carried it home directly, chopped it and stored it as firewood.

Finally, Lu Yunfeng gave some advice to the two little guys and asked them to go home before the evening.

It's spring now, and Lu Yunfeng doesn't know what season does the super-large giant appear? Because the temperature inside the city wall is very good, it can almost be called spring, with dense mountains and forests and abundant water sources. Similar to the Sichuan Province in China, it can be called the country of Tianfu. However, Lu Yunfeng feels that the technology tree in this world seems to be crooked. It has powerful steelmaking technology and can invent artillery and three-dimensional mobility devices, but there are no electronic products. Medical skills are also very medieval pharmacy. Simply put, this is a background in the medieval European era, and then there are more artillery and three-dimensional mobility devices, as well as giants.

The world of giants is full of all kinds of secrets. Where did giants come from? Why did giants only eat humans? Why did giants not excrete, but the people who eat them finally vomited out? Who built the huge city wall fifty meters high? Why did humans live here? Also, where did Arnie and Lenner and Hoover come from? Why did they become giants? And why did they destroy the gates of human walls? What kind of secrets are hidden in all this?

Lu Yunfeng really wanted to reveal these secrets, but this world was originally created by relying on incomplete plots that Lu Yunfeng did not understand. Can the secrets of this world be discovered? Lu Yunfeng also needs to explore it himself.

In the past six months, Lu Yunfeng did not rush to go outside the city wall to check it out. He just patiently lived a life of a little field in Nongfu Spring. By the way, he inquired about the addresses of the protagonists in this world, and wondered what kind of identity he would participate in the story of this world in the future.

First of all, Allen's mother must be saved. Such a good woman was eaten by a giant. She couldn't bear it. In addition, she killed the giants and killed them one by one. Let's see how many giants are there? If the giants are killed, what kind of people will be drawn in the end?

Lu Yunfeng can’t help it in an interesting world. Super large giant, you should appear!

The giant had not appeared yet, but the Investigation Corps inside the wall was making trouble again. I heard that they walked out of the wall with great fanfare and wanted to build a first stronghold outside the wall for humans. As for the result? Humans are looking forward to it very much, but whether they can succeed depends on the information after the Investigation Corps comes back.

"I saw that the Investigation Corps is so handsome. I must become a member of the Investigation Corps in the future." On this day, Alan took Mikasa to Lu Yunfeng's house again, but judging from his speed of eating, he probably had a free meal as the main purpose.

"Alan, don't always think about joining the Investigation Corps, okay?" Mikasa finally expressed her dissatisfaction: "It's too dangerous."

"Even if it is dangerous, it is still a contribution to the future of mankind. I don't want to stay in the city wall like a domestic animal for the rest of my life." Alan turned a blind eye to Mikasa's concern and was still immersed in his own fantasy: "I must go to the outside world to see it, even if it's only a moment. I want to see the outside world."

Mikasa was silent.

Lu Yunfeng nodded with a smile: "It is of course good to have such an ideal, but I still said that before you go out, you must have the ability to protect yourself. With just fighting skills, you cannot survive. So entering the training class and learning to use three-dimensional mobile devices is also a guarantee for your life safety."

"Yes." Allen nodded repeatedly: "I will definitely enter the Investigation Corps."

"Before that, you have to convince your family first." Lu Yunfeng glanced at Mikasa and said, "I heard from Mikasa that your mother seems to be very opposed to your joining the Investigation Corps. After all, she only has you, and if something happens to you, she..."

"..." Allen was silent. After a long time, Allen spoke: "I know this will make her sad, but I also have my own ideals. If I can't walk out of the wall and go to the outside world to take a look. Even if I live my life safely, I will definitely die with my eyes open."

"Is that true..." Looking at Alan like this, Lu Yunfeng sighed and said, "Ideals and reality always have conflicts. But from my personal perspective, I support you very much. Alan."

"Brother Lu..." Allen smiled.

"Humans always need to keep going in to make progress. Many people do not understand the Investigation Corps and think that they are wasting people's money and welfare in vain. But how could they understand that it is precisely because of the Investigation Corps' exploration and sacrifice that humans have a certain understanding of the weaknesses of giants and gives humans hope to defeat the titans. Therefore, for humans, everyone in the Investigation Corps is very great, and I hope you can become a great person in the future." He paused: "Although this will make your family worried and even sad."

"I understand." Allen focused: "I will definitely become a hero among human beings, and my mother...I will explain it to her clearly."

Looking at Allen's heartfelt look, Lu Yunfeng smiled slightly and said, "But don't worry now. After all, you are only ten years old. Even if you want to enter the training class, you have to wait a few years later. In the past few years, you will be able to stay with your parents and family, and then practice fighting skills. Don't think about anything else, just let it go."

"Yes, I get it." Allen nodded with a smile.

It was almost evening when the two little guys were leaving again. At this time, Lu Yunfeng called out to Mikasa: "I have a few words to say to you alone, Alan, go ahead and wait."

"What should I tell Mikasa alone?" Alan was very curious, but he still obediently went to the intersection in front to wait for Mikasa.

"Brother Lu, what do you want to say to me?" Mikasa asked after Alan left.

"Mikasa, I have thought about something for a long time. I always feel that you are still young and should wait to tell you. But I always have a bad premonition recently. It seems that something big is going to happen, and it is definitely not a good thing. In order to avoid an accident, I decided to tell you about it in advance." Lu Yunfeng said with a serious expression.

Mikasa's expression also became solemn: "Brother Lu, please tell me."

"Mikasa, I have actually observed you and Alan for a long time." Lu Yunfeng said and surprised Mikasa: "Actually, I am a warrior from the East China, and China and Japan are two adjacent countries. Do you understand what I mean?"

Mikasa opened her eyes wide, looked at Lu Yunfeng's black hair and black eyes, and pursed her lips: "Brother Lu, can you say that you are from my hometown?"

"From the perspective of the country, we are not the same country, but in terms of geographical location, we are very similar. Don't you think we look very similar? They all have black hair and black eyes, and their skin is slightly yellower than others." As he said that, Lu Yunfeng pulled Mikasa's hand and rolled her sleeves. Then the two compared the color of the skin. It was indeed the same.

This caused a great impact on Mikasa's heart: "Brother Lu..."
To be continued...
