The plan

At the sound of a bang, all the Anbu ninja outside rushed in, followed by a series of thuds as they hit the ground. The harder they tried to get up, the less they could move. Some of their masks had already shattered. Seeing blood streaming from their eyes, mouths, and noses, Tobirama Senju was filled with guilt.

Just then, Shimura Danzō and Hiruzen Sarutobi also wanted to try the new contraption Itō Yuying had brought back, so they went to take a look together.

When the two saw the situation inside, Hiruzen Sarutobi was about to rush in to save them, but Shimura Danzō stopped him and shouted, "Do you want to end up like them too? You're fast. Hurry and get our junior!" "Oh, right!" Hiruzen Sarutobi came to his senses and, without further hesitation, dashed toward Itō Yuying's home.

A few minutes later, Itō Yuying appeared before Shimura Danzō with Hiruzen Sarutobi. Without a word, Itō Yuying went inside. The moment he stepped in, he was flattened by the pressure. Then he unleashed his Ki, rushed toward the switch, and pressed it with one hand. The pressure on everyone's bodies eased, and they gasped for breath. Itō Yuying took out a Senzu Bean and fed it to Tobirama Senju. A moment later, Tobirama Senju stood up, full of energy. "First, take everyone who passed out to the hospital. Yuying, let's talk outside." Tobirama Senju had been shaken by the experience too. They went out to an open space, where he first praised Shimura Danzō for remaining calm and composed.

Shimura Danzō replied modestly, "It's all thanks to your teaching, Sensei."

After offering Hiruzen Sarutobi some encouragement as well, he said, "Yuying, tell us about this Gravity Chamber." Itō Yuying explained its functions and benefits. Tobirama Senju nodded. "Then could we make a Gravity Chamber suited to us ninja?" "Of course!" Itō Yuying said. "Feel free to study it. Oh, right, I recommend Orochimaru. He has a real talent for research." Tobirama Senju thought for a moment and nodded. "Orochimaru is a clever boy. I'll have him join me in researching it."

"All right, it's getting late. Go back and rest." "Yes." Everyone left.

The night passed without incident. The next day, Itō Yuying arrived at the training ground and was a little bewildered by what he saw. What's going on here? A large area around it had been fenced off, and workers were doing construction. Itō Yuying asked a ninja what was going on. The ninja replied respectfully, "By Lord Hokage's orders, this training ground has been designated Konoha's classified training ground." "Oh, I see." Itō Yuying nodded, then flew to the Hokage Building.

"You're here, Yuying." "Yes, Sensei. Do you have some plans for the training ground?" "Here's what I'm thinking. I plan to turn it into a secret training ground. Those allowed to train here will be the elite among the elite, the strongest of the strong, and they must be absolutely loyal to Konoha."

"Then how will we handle secrecy?" Itō Yuying asked.

"I'll ask my sister-in-law to develop a Sealing Jutsu. Anyone who reveals the training ground's secrets will suffer a backlash." Tobirama Senju did not elaborate, and Itō Yuying asked no further questions. "I'm planning to establish a new department, with you as its head. You'll also manage that training ground from now on and answer only to me." "Yes, Sensei." "Mm. I haven't thought of a name for the department yet. Give it some thought when you get back. All right, you probably won't be able to train there for the next few days. Make do with another training ground for now!" "All right, I'll be going, Sensei." "Mm, go ahead!"

Rising slowly into the air, Itō Yuying flew toward the training ground. When he arrived, everyone was standing together in one spot instead of training. Mm, very good awareness of secrecy.

"All right, everyone, follow me. We're moving somewhere else." The whole group followed him out. Once they arrived at another training ground, Itō Yuying briefly told everyone about his conversation with Tobirama Senju. "Does that mean we'll all be founding members?" Jiraiya asked excitedly. Itō Yuying nodded. "You could put it that way."

"Yeah! I'm going to train hard and leave a good impression on our juniors!" Then he hurried off to train.

A few months later, they returned to the training ground. Looking at the newly renovated grounds, they were all dumbstruck. It was huge, truly enormous. There were woods, tall mountains, waterfalls, rivers, hundreds of large training areas, laboratories, cultivation plots, a hospital, a school, dormitories, a cafeteria, and hot spring baths. There was even an area reserved for over five hundred Gravity Chambers. This was sheer extravagance.

Jiraiya stammered, "I-is all this for us?" Itō Yuying was just as astonished. "It seems so."

Then cheers erupted. Orochimaru's eyes gleamed as he looked at all the equipment in the laboratories, constantly licking his lips. Tsunade wandered around the hospital, so delighted that a snot bubble emerged from her nose. Hatake Sakumo and Might Duy walked around the training areas. Looking at all the training weights, Might Duy was incredibly excited, touching one and examining another. Hatake Sakumo looked at a row of assorted weapons, picked up a short sword, and swung it a few times. Every weapon in the row was made of chakra metal, and he kept stroking them. Jiraiya, that little pervert, kept prowling around the bathhouse. Hyuga Yeyang and Uchiha Hanyue wandered off to one side with indifferent expressions, but a closer look showed their eyes constantly darting around and their grins stretching all the way to their ears.

"What do you think, Yuying?" "It's stunning. This is far too luxurious." Tobirama Senju laughed. "You'll be in charge here from now on. In the future, whether it's the Hokage, Elite Jonin, or recruits selected for the Anbu, they'll all come from here. So you'll have to work hard as department head!" Itō Yuying smiled wryly. "Sensei, that's a lot of pressure!" "Haha, I'm here, so don't feel pressured. Just focus on teaching those children well. If any of them have the talent to cultivate Ki, you must take proper precautions." "Yes, Sensei. I'll keep a safeguard in place."

"Oh, really?" Tobirama Senju grew interested. "Tell me about it."

Itō Yuying smiled. "I'll put a wisp of my own Ki into everyone's body. That will help them sense Ki's existence quickly and also help them cultivate their own Ki faster. Most importantly, I can control that wisp at will. If there are any spies or traitors, I can make it disappear at any time. They'll never be able to cultivate Ki again, and they won't be able to use any jutsu related to Ki."

Why does that sound so familiar? Tobirama Senju thought as he listened. Then he asked, "Then the Ki inside our bodies..." Itō Yuying nodded. "I can remove that too. But if you tightly wrap the Ki you've cultivated yourselves around mine, I won't be able to remove it. That's the only way. The Ki I gave you back then had its connection to me severed. Although I can control it, if you have enough Ki to wrap tightly around it, there's nothing I can do." Tobirama Senju nodded. Shimura Danzō and Hiruzen Sarutobi silently resolved to work hard at their cultivation when they got back.

"What if those future students cultivate very powerful Ki?" "From the beginning, I'll leave them with Ki that remains connected to me. No matter how much Ki they have, I can draw it out with a single thought."

Tobirama Senju nodded in satisfaction. "Good. As long as you're confident." "Don't worry, Sensei! Oh, right, there's something else I need to tell you." "Oh? What is it?" "Once your Ki cultivation reaches a certain level, it can be passed down to the next generation." As soon as Itō Yuying said that, Hiruzen Sarutobi and Shimura Danzō immediately pricked up their ears and listened closely. Seeing the two practically pressing up against him, Itō Yuying hurriedly said, "Once you cultivate it to a certain level, you can consider it a Kekkei Genkai. It can be passed down to the next generation, and it won't be subject to any control. Even I won't be able to control it. The only restriction will be aptitude."

Hiruzen Sarutobi's and Shimura Danzō's eyes lit up, and they chuckled foolishly.
