Hokage: Immortal, I Open Unlimited Eight Gates

Uchiha Chiba nodded. "Then I'll bother you, Nawaki."

"Why are you so polite? Chiba, wait a minute. I'll call my sister right now."

When Senju Nawaki left, Uzumaki Kushina said, "Goodbye, Chiba. I'll go find Mikoto first."

"Well, bye, Kushina."

When Uchiha Chiba saw Tsunade, half an hour had passed.

"Sorry, Chiba. I slept late last night."

Tsunade covered her mouth and yawned as she spoke.

"Sister Tsunade, why don't you go get some sleep? I'm not in a hurry."

Uchiha Chiba saw that Tsunade didn't seem fully awake, so he immediately suggested.

Tsunade shook her head. "No, I can't fall asleep even if I go back to bed now. Let's not talk about it for now. Have you read the books I gave you?"

"Well, I've read The Basics of the Human Body and The Illustrated Medicine Manual, but I haven't had time to read the rest yet."

Tsunade nodded. "Okay, then today I will test your knowledge of these two books and guide you in the practice of Sage Jutsu."

Hearing that there was going to be an exam, Uchiha Chiba looked around curiously and then focused on Tsunade. "Sister Tsunade, where are the test papers?"

"Test paper? What test paper?" Tsunade was a little confused.

"Didn't you say you were going to give me an exam? How can you do that without test papers?" Uchiha Chiba was equally puzzled.

At this, Tsunade realized what he meant and waved her hand. "No need for that. I'll just ask you the questions and you can answer them later."

In fact, Tsunade had originally planned to prepare test papers, but since she didn't know how much Uchiha Chiba had studied, it was difficult to control the scope of the questions. So, she decided to skip it.

Of course, the most important reason was that she wanted to be lazy. After all, preparing test papers took a lot of time.

Uchiha Chiba had to agree. "Okay, when will we start?"

An evil smile appeared on Tsunade's face. "Now, okay. I'm going to start asking questions. By the way, Chiba, if you answer more than three questions incorrectly, you will be punished. So, make sure to answer carefully. Got it?"

Seeing Tsunade's smile, Uchiha Chiba swallowed unconsciously.

"Sister Tsunade, can you tell me what the punishment is?"

"No, it's boring to explain it. Okay, let's begin. First question..."

Half an hour later, the exam ended.

Tsunade shook her head with regret. "You only got two questions wrong. It seems there's no chance to use the punishment, tsk tsk."

After hearing Tsunade's words, Uchiha Chiba couldn't help but wipe the sweat from his forehead.

Fortunately, he had been studying hard after school in the past few days. Although he didn't know what the punishment Tsunade was referring to was, judging from her earlier smile, it was probably something unpleasant.

Tsunade looked at the sweaty Uchiha Chiba and smiled. "Okay, the exam is over. Let's take a rest for now, Chiba."

Hearing this, Uchiha Chiba nodded. He really needed a break after that.

The questions had been painful, especially since Tsunade didn't say whether he had gotten them right or wrong, instead watching him with a smile before moving on to the next one.

After resting for 10 minutes, Tsunade clapped her hands. "Okay, you've rested enough. Now follow me."

Tsunade led Uchiha Chiba through the yard and brought him to the door of a room.

She pointed to the room. "This is where my second grandfather used to store the ninjutsu he developed. After he left, those ninjutsu were sealed in the Sealed Book, and this room became empty."

"You can practice here from now on."

Senju Tobirama's room where ninjutsu is kept?

Uchiha Chiba thought it was probably not ninjutsu but forbidden techniques.

He secretly remembered a joke about Senju Tobirama from his previous life.

[Senju Tobirama: "Brother, I developed another ninjutsu."

Senju Hashirama: "Is it Water Style?"

Senju Tobirama: "No."

Senju Hashirama: "Oh, then ban it."]

Thinking of this, Uchiha Chiba almost laughed out loud. He quickly covered his mouth to prevent Tsunade from hearing him.

Otherwise, explaining to Tsunade that he didn't respect Senju Tobirama would be difficult.

After a moment, Tsunade opened the door.

Uchiha Chiba looked around and saw that the room was quite clean, and it seemed that someone cleaned it frequently.

His eyes were drawn to a fish tank, which was half the size of an ordinary refrigerator, standing in the center of the room. Several fish were swimming around in it.

Next to the tank was a small table that resembled an operating table.

Tsunade pointed to the fish tank. "The materials are ready for you. You can practice here later."

"Now let me show you how to do it."

With that, Tsunade walked up to the fish tank, grabbed a fish, and a layer of light blue chakra appeared on her other hand.

Chakra scalpel.

Then Tsunade made several swift gestures on the surface of the fish, and the fish, which had been swimming around just moments ago, became still instantly.

If it hadn't been for the fish's mouth opening and closing, Uchiha Chiba would have thought the fish was dead.

Tsunade looked up at Uchiha Chiba. "I used the Chakra scalpel to sever the nerves of this fish. Now I'm going to show you how to use the mystical palm technique to heal it."

Tsunade placed the fish she was holding on the small table beside her. A stream of green chakra slowly emerged from her hands.

She placed her hands on the fish, and within seconds, the fish that had been motionless came back to life.

After tossing the fish back into the tank, Tsunade looked at Uchiha Chiba. "Chiba, did you see what I did with the mystical palm technique just now?"

Uchiha Chiba nodded eagerly. "Yeah, I saw clearly. But, Sister Tsunade, can you teach me the Chakra scalpel?"

Uchiha Chiba felt that the Chakra scalpel was perfect for him as a berserker.

In the future, if he encountered an enemy he didn't want to kill, he could simply use the Chakra scalpel to sever their nerves, making them lose their combat effectiveness instantly.

And without the help of medical ninjas, they wouldn't be able to recover for a while.

Thinking of this, some perverted thoughts popped into Uchiha Chiba's mind.

In the future, if he met a beautiful female ninja from an enemy country and used the Chakra scalpel to sever the nerves in her hands and feet, wouldn't that give him the power to do whatever he wanted? ( ́.✪ω✪.`)

Wait, this situation reminds him of something from his previous life—a time-stopped series of Little Days?

Infinite Lord, sin, sin, sin.

Uchiha Chiba quickly discarded this idea after silently chanting the word.

He was a good young man—how could he be corrupted by his small life?

Tsunade, unaware of Uchiha Chiba's momentary lapse into perversion, continued, "It's not difficult to start using the Chakra scalpel, but if you want to master it and cut nerves effectively, you'll need a lot of practice."
