"Kiyu, do you want to learn ninjutsu with me?"

On the fourth floor of the only hospital on the island, Inoue Izumi stood in front of Kuroyui's bed and asked.?

"I want to be a ninja as powerful as you."

Kuroyuyi lay on the hospital bed, struggling to lean his head against the edge of the bed, looking at Inoue Izumi beside the bed.

"Why?"

Inoue Izumi raised her eyebrows and asked faintly.

"Because only then can I have the ability to repay your life-saving grace."

Hei Yuyi couldn't help but recall that he was abandoned by his parents since childhood. He walked alone to a wilderness and met a fierce wolf. When he was about to be bitten to death by the wolf, Inoue Izumi appeared, killed the wolf king with one knife, and rescued Hei Yuyi from the wolf's mouth. So in Hei Yuyi's heart, Inoue Izumi was his benefactor and the object of his admiration. He hoped that one day he could be so strong, and only by becoming stronger could he be able to repay his life-saving grace.

"Okay, then I'll tell you the basics first." Inoue Izumi stared at Kuroyuyi's eyes, and saw that Kuroyuyi's sincere eyes were either grateful or worship. He couldn't help but sigh in his heart that Mariko's forbidden technique was really amazing.

"kindness."

If you want to become a qualified ninja, in addition to martial arts, you must pass the five compulsory subjects of "food, incense, medicine, qi, and body", commonly known as the "Five Ninja Paths".

"Food" refers to the food of a ninja...

"Scent" means that the ninja can judge the other party's economic situation and status based on the smell on the clothes...

"Medicine", an excellent ninja is usually a doctor and drug expert, good at using various plants and herbs in the forest to cure injuries and treat diseases...

"Qi" means that ninjas focus on self-cultivation, so that they can concentrate in actual combat, be decisive and brave, and remain unchanged...

"Body" means that ninjas focus on muscle and joint exercises, and at the same time, they exercise themselves in combination with restoration methods such as meditation, breathing, massage, acupuncture, etc. to adapt to the needs of various martial arts.

...

Sakai, Sugiyama, Miyazawa, and Ukoi were all sitting in the hall on the first floor of the hospital. Looking at the stairs leading to the upper floor, their eyes were filled with worry. Their current strength could only barely enter the first floor.

"Instructor, how is Heiyu?"

The instructor who has been in charge of training them for the past two years walked down from the second floor.

"He's fine, you're all back. You've been here for several days and the training has been delayed." The instructor walked up to them and said.

"It's really okay?"

Sakai and Sugiyama asked again in doubt.

"It's okay, it was Lord Mariko who personally treated him." When the instructor said that Lord Mariko, his eyes were full of yearning. The woman who had beauty and strength, I really hoped that he could go up to the third floor in his lifetime and be lucky to be treated by Lord Mariko once. That was something worth showing off.

"Mariko? Is he a very powerful doctor?" asked Yuna Sakai.

"Well, she is the imperial genius doctor in charge of the people. She has Gao Cao's medical skills that can bring about death. Hei Yu's injury is nothing to her. She has been successfully treated. The next thing is to be at ease." The instructor said boastingly.

They didn't know how high Mariko Akashi's medical skills were. After all, they were not qualified to get her treatment. They just heard that the people on the third floor had returned with serious injuries after completing highly dangerous tasks outside. When they were in danger, they were fortunate to receive her treatment and completely recovered without exception.

After hearing what the instructor said, they felt relieved.

"Instructor, why do we have to separate? Isn't it good for us to train together?"

Wu Xiaohei complained in a low voice, receiving a notice two days ago, they have been arranged to have an instructor and guide each other. After they are separated, she can no longer be lazy. If the training is not completed, no one will give her something to eat.

"This is the arrangement above. It is for your own good. Those who provide individual guidance and training for you are all the masters on the third floor. They are our diamond-level figures of Iga. It is your honor to be able to guide you."

Perhaps it is because I may not meet again in the future. Seeing that the students I trained for two years were going to hand over to others, the instructor who was usually ruthless also talked too much.

“Can’t we go up?”

Miyazawa Nan looked at the stairs leading to the upper floor and clenched his fists.

"Want to go up? Then follow your new teacher to study hard!" The instructor looked at them with a cold smile.

"We will definitely go up."

Sugiyamaji, Inoue Yona, Miyazawa Minami, and Ukoi said in unison.

The people waiting for treatment on the first floor heard their voices, just looked at them strangely, and did not make any other moves.

Children, having goals is a good thing, but they don’t know how far they can go in the future.

They used to yearn for going up to the third floor or even the fourth floor, but now, most of them just want to go up to the second floor.

"Let's go, Hei Yu's injury will not be healed in one or two days. And when he heals, he will directly send him to the new instructor for training, and he will not come down to see you. I will take you to meet the new instructor now and be mentally prepared. The training you will receive next will be more difficult than mine."

The wind blows in the sun, and the scenery flows westward. Two years have passed in a hurry.

Under a turbulent waterfall, a shirtless boy holding a copper sword nearly two meters in his hand was slashing and slashing again and again. Every time he waved the copper sword, Hei Yuyi's arm would burst out blue veins, enough to show that it was in the copper sword.

Under the teenager's chopping, a crack was clefted out of the waterfall, and the water flowed, and after the sword passed, it was almost stitched.

The boy's head and body were wet with the splash of water.

The hot sun also adds a bit of coolness to the teenager.

But the efforts of the boy cannot be proved by sweat.

However, the gradually strengthening muscles and fading scars on the boy's body are enough to prove that Hei Yuyi has not been white in the past two years.

The sun swept directly above the waterfall and moved to the west.

The copper sword originally in Hei Yuyi's hand was stably inserted into the water beside him, leaving the torrent to hit him without moving.

Hei Yuyi still repeated the previous slash.

The copper sword in his hand was replaced by a wooden sword, which was broken than a copper sword and thinner than a copper sword.

A wooden sword that seems very light.

A wooden sword that seems to be broken by a waterfall at any time.

However, Hei Yuyi used this wooden sword to slash the same effect as the bronze sword on the waterfall. The same sound of breaking through the air, the same destructive power, the same accuracy, and the same degree. Each time he slashed, the same amount of water splashed.

This is the training results of Hei Yuyi over the past two years.

At night, the clear water surface reflects the sky full of stars, like a Milky Way.

"Heiyu, it's time to eat."

Inoue Izumi walked to the lake where Hei Yuyi trained, and found a big stone to put down the bamboo basket.

"ah--"

Hei Yuyi's eyes moved, and through the faint light of the moonlight, he saw the reflection in the Inoue Spring Water clearly, and swung his sword down. When the sword was about to slash the reflection of the Inoue Spring Water, he turned his body and stepped on the lake water and rushed towards Inoue Spring.

When he was two meters away from the shore of the lake, Hei Yuyi kicked down, jumped up, and raised his sword toward Inoue Izumi who was standing on the shore.

Looking at the fiercely fierce Hei Yuyi, Inoue Izumi did not dodge, smiled slightly, and raised her left hand.

"Master, be careful."

After practicing the move for two years, Hei Yuyi naturally knew the power of his move.

Although it seems not very powerful in front of the turbulent waterfall, it can actually break a tree with a diameter of nearly half a meter.

Inoue Izumi did not flash, and her eyes accurately captured and predicted the direction of the sword falling.

The index finger and middle finger of the left hand stretched out, firmly clamping the tip of the wooden sword.

Just as Inoue Izumi was about to open his mouth, Hei Yuyi took a trace of arc at the corner of his mouth, held the hilt tightly, used the hilt as a fulcrum, and his body rotated forty-five degrees with forward inertia, and his feet flew towards Inoue Izumi.

"bump."

Inoue Izumi stretched out his right hand and took a step back to stand firmly, blocking Kuroyuyi's scud attack.

"thump."

Inoue Izumi suddenly shook his right hand and opened the tip of the wooden sword with his left hand. Hei Yuyi's body flew out with the wooden sword and fell into the lake.

"Haha, Master, you finally got your right hand."

Kuroyuyi struggled to stand up from the lake, wearing a embarrassed look, wiped his face and looked at Inoue Izumi with a smile.

"Come up and have a meal."

Inoue Izumi turned around and said tepidly, walking towards the stone where the rice basket was placed, with a hint of relief at the corner of her mouth, and reached out to uncover the lid on the rice basket and brought the meal out of it.

“Wow, it smells so good, the chicken tastes.”

Hei Yuyi shook his nose, smelled the fragrance of food, quickly walked out of the lake, and came to the stone.

"Give it, wipe it."

Inoue Izumi picked up the white towel on the rice basket and threw it on the head of Hei Yuyi who was about to reach out to get the chicken legs.

"oh."

Hei Yuyi wiped his head with a towel with his left hand, and picked up the chicken legs with his right hand and put them on his mouth to chew it. Every day, such high-intensity training consumes a lot of energy.

"Kei Yu, after training for two years, it is time for you to understand your strength. I will take you to discuss with others tomorrow." Inoue Izumi did not accompany Kui Yuyi for dinner, but took out a thermos bottle with a lid from the rice basket, opened the lid, poured a cup of tea and handed it to Kui Yuyi who was eating in the sea.

"Huh? Are you Sugiyamaji and the others? I haven't seen them for a long time, and I don't know how strong they are now." Kuroyuyi put down the towel, took the teacup, wrapped the food in his mouth, chewed it in chaos, took a sip of tea, and swallowed it with the tea.

"It's not with them, nor with Iga's people, but with another ninjutsu school, Koga."

"Kahe? A? Yi, B? It sounds very powerful."

"Why, don't have confidence? Or do you doubt what Master gave you?"

"No, I have confidence."
