Seeing everyone's expected expressions, Li Yu said to Xiaodan: "How about it, Xiaodan, can you see if these potions are enough? Are there any problems?"

"It's too much. I can't use it up. Besides, I haven't made so many bottles. Even if one person has one bottle, it's still far from being able to hold so much poison." Xiaodan saw this.

To others, these things may seem too scary to touch, but to Xiaodan, these are all treasures.

Regarding this issue, Li Yu also has his own thoughts, that is, once he encounters a real mortal enemy, especially those who want to kill him, he can retaliate in kind.

"You can also soak all your crossbow arrows in poisonous water. The power of the soaked arrows will be increased several times."

After Li Yu finished speaking, Xiaodan's eyes lit up: "Yes, why didn't I think of that!"

"It's just you. If you thought about it, all the pigs would climb the tree." Erhan came out and quoted what Li Yu once said.

When I heard the ridicule to me, I couldn't help but say something. Xiaodan turned around and punched Erhan. In the hero ranking competition, although Xiaodan was not good at Erhan, Erhan might not be able to get an advantage.

Seeing the strange punch, Erhan quickly dodged away as if facing a powerful enemy.

"You are a dog, and you always bite people?" Erhan, who was making a joke, yelled and avoided Xiaodan.

"Okay, you guys should stop making trouble and listen to the young master!" Seeing the situation in front of him, Liu Gui came out to stop him.

"Xiaodan, there is a task that you need to complete now." Li Yu said to Xiaodan.

"Young Master, are you talking about dealing with the poisonous potions in front of you?"

"That's not it. Do you still remember the flying lantern we made?" Li Yu reminded Xiaodan.

"Remember, of course I remember, didn't we succeed in that? Does the young master have any new ideas?"

Speaking of this, Xiao Dan's interest suddenly became high, because once Li Yu had any new ideas, they would definitely be of interest to her.

"I have an immature idea, that is, I want you to make some big flying lanterns."

"How many big ones should I make? How big should I make?" Xiaodan asked with some confusion.

"I want you to make something that can not only seat people, but also do some simple air transportation!"

"Air transportation?" Xiaodan was even more puzzled.

Li Yu knew that if he told them something like this that they had never seen before, they would probably not believe it anyway, so he still had to be patient and said to Xiao Dan: "Now we have two major problems that need to be solved.

, The first is the problem of silver transportation in Yanyu Village. My father has already taken action there and surrounded it with water. Even if we all mobilize, we may not be able to get it out from there. The only way is to transport it from the air. "

"How is this possible? Young Master, if you get a bigger flying lantern, you might be able to get a few hundred taels of silver or something, but if you want to transport it in large quantities like you said, it's not that easy to do. There's also the problem of controlling the direction.

, this is a difficult problem, even if we create giant lanterns like you mentioned, we probably won’t be able to control their landing direction."

Xiaodan is indeed a talented person who is proficient in this field. As soon as Li Yugang mentioned this, Xiaodan immediately thought of the key issue.

"So, can the thing I want you to create be able to seat people?" Li Yu said with a smile.

If it weren't for the difference between master and servant, Xiaodan really wanted to go up and touch the young master Li Yu's forehead. He said this, which is not an immature idea, it is clearly a whim. Xiaodan's thoughts about Li Yu this time are...

He shook his head and rejected it.

"If that flying lantern can go up to the sky, I believe we will be able to make a lantern that can sit on people, but this is a dangerous job." At this time, a fat guy with a round belly and waist stood up and said, the biggest feature of this person is

Fat, fat eyes can no longer be seen. When people see him, their eyes are just lines.

"This is not a dangerous job, it is clearly a life-threatening job." After hearing the whole story, Zhu Hongying also stood up and said.

Li Yu didn't pay attention to what Zhu Hongying said, but was very interested in what the fat man said.

"This is..." In fact, Li Yu had already guessed a lot about this person.

"Young Master, this is the person I asked for for you - Fatty Qu, one of the four major talents of the Imperial College."

Xiaodan introduced from the side.

"Can you make a flying lantern with people on it?"

Li Yu asked with great interest.

"Your Highness, to be honest with you, I have been studying your flying lantern a few days ago, and I have also thought about building a large lantern that can carry more things and go up to the sky. However, there are still three problems that are difficult to solve."

"Oh!" Having said this, Li Yu's interest greatly increased and he asked excitedly: "What problem is difficult to solve? My Highness can help you solve it."

"First of all, I have carefully thought about the flying lantern that His Highness made. It is really ingenious and unbelievable. But after understanding the doorway, I know that Your Highness used the heat of the candle to rise up. It is not surprising.

Already."

Hearing this song, the fat man expressed contempt for Li Yu's flying lantern. Erhan and others were about to come out to criticize, but were stopped by Li Yu, who urged with a smile: "Keep talking..."

"Later, when I was young, I also made a larger flying lantern, but it soon failed. There are three reasons!"

"First, the heat generated by the fuel is not enough. Nowadays, the fuel for lanterns mainly relies on candles. Even if more are lit, the gas is insufficient and it is still not enough to bear more weight. So if you want to make a larger flying lantern, even

As His Highness said, it can seat people, carry cargo, and be used as air transportation. The first thing to solve must be fuel."

Brilliant, this inconspicuous Fatty Qu got to the point right away. As expected, Li Yu also knew about the fuel. Hot air balloons in previous lives used methane and natural gas as fuel, but now they use candles.

The amount of heat is in the sky and in the earth.

"The second is the lantern stand. Nowadays, lantern stands are generally made of bamboo slices and bamboo strips with a certain degree of elasticity. The disadvantage is that they are flexible but not flexible enough. Let alone a person, even if it is a lighter object

, it will definitely break.”

Li Yu nodded: "That makes sense, what about the third one?"

"Third, the gray cloth used to make lanterns. The ones on the market now are gorgeous and beautiful, but they are very breathable. In addition to supporting the lanterns to rise, they will also disperse to a certain extent, so they cannot stay high in the sky for a long time."

After hearing this thorough and in-depth analysis, Li Yu began to wonder, did this girl come from time-travel like him, and what he said was more thoughtful than he thought?

"If I solve all the three problems you mentioned, can you make a larger, heavier-bearing, and controllable flying lantern?"

After Li Yu finished speaking, he looked at Fatty Naqu with great anticipation. Not only Li Yu, but also Wan Ling'er and Zhu Hongying, who looked indifferent, were attentively waiting for Fatty Naqu's response.

"From an idea perspective, it is possible, but controlling the direction and maneuverability is still a difficult problem to solve."

"You don't have to worry about that. His Highness can help you solve it. Do you still have any questions?"

Seeing the expectant look on Li Yu's face, Fatty Naqu said calmly: "Then there will be no problem."

"Okay, I'll give you three days, three days at most, and I will do my best to satisfy you with whatever you need. Can you make a flying lantern that can seat people and carry cargo?"

When Li Yu spoke seriously about this issue, Fatty Naqu was a little stunned, but still reluctantly said: "Your Highness, I will try my best."

"It's not about giving it a try, but you have to get it out for me. Otherwise many things that follow will not be possible, do you understand?"

Seeing Li Yu's pressing look, Fatty Naqu said angrily: "Your Highness has solved the above problems. I believe this is not difficult to produce."

"Okay, it's a deal. Xiaodan, can you solve the three problems I just mentioned?"

When Li Yu first told this, Xiaodan was still in the dark: "What's the problem?"

Then Xiaodan knew what Li Yu was talking about. He touched the back of his head with one hand and said with a silly smile: "Young Master, are you kidding me? The three questions you mentioned are: what kind of fuel, what kind of gray cloth, and what kind of solid

Where can I find the bracket?"

"Aren't you usually very smart, but why have you become more and more stupid lately? You can use the fuel from our incendiary bombs, and you can use the gray cloth we use to make rainproof combat uniforms. As for the bracket...

..."

Li Yu thought about it for a moment and asked, "Liu Kui, do you still have the alloy scrap left over from when you made the military spurs?"

"Yes, there is, but not much left. That thing is light, not easy to break, and more importantly, more durable than ordinary fine iron." Liu Kui didn't know what Li Yu suddenly asked him for, but he still told the truth.

answer.

"That's all. If you don't have enough, you can get some more. In the past two days, you will be responsible for making the lantern brackets that Fatty Qu needs. Xiaodan, you will be responsible for providing all the materials, and let Arnoste help Fatty Qu complete the flying lantern together.

For the production, what I need is progress. It is best to complete it within three days, otherwise many subsequent things will not be possible."

"Understood, Young Master." Xiaodan waited for Li Yu to explain clearly, and realized that what Fatty wanted was all the secret weapons carefully refined by the previous Young Master, but many of them were not used.

Like the incendiary bomb, the unknown gas stored in a special iron casting device can instantly erupt into a huge flame that is several feet long, and the aforementioned gray cloth made of rainproof cloth.

That fabric is extremely light. It is not only windproof and rainproof, but more importantly, it is extremely strong. When they compete for the hero list, if they wear combat uniforms made of this kind of gray cloth, the degree of damage will be smaller and it will be more durable.

Wear-resistant, not ordinary strong.

These things were not done in a day or two. Li Yu had already done some of these things before Xiaodan arrived at Li Yu's Prince's Mansion. Only Li Yu knew how to do many of them.

, but Li Yu said it, Xiaodan still had it when Li Yu mentioned these things.

The biggest gain this time was none other than Fatty Naqu. He never thought that he had wanted to develop a large flying lantern a few days ago, which could realize the myth of human beings going to heaven, and that it would be solved so soon.

Although even he himself thought it was a bit whimsical, the omnipotent prince in front of him really solved three problems for him that he thought were difficult problems. The rest was not that difficult. For him, Qu

The fat man is very confident, because this is what he was born into.
