Chapter 222: Initial preparation
Kaida only showed a little anger but nothing much. He had already witnessed such vile acts many times when he read the memories of so many bandits previously.
"The reason I told you that is so that you won't pity him for what is going to happen next," Mitsuru added.
Kaida just nodded his head and went near Mitsuru. She directly started the class.
"For Mitotic Regeneration Jutsu, you need a clear understanding of how a human body works—what each organ, skin tissue, bone, and blood is made of, and how you can reconstruct it. For that, we are going to use him," Mitsuru said.
Kaida nodded again as Mitsuru started putting on her gloves and took out a scalpel. Kaida, by instinct, began preparing anesthesia.
"We don't need that. Anesthesia will slow down his nerves, and you won't see the clear movements. Also, he doesn't deserve that," Mitsuru said.
Kaida then came out of his daze. Even though he had accepted his fate, he once lived in a peaceful world. Despite having killed many people himself, he had somehow maintained a bit of innocence. Such cruelty always seemed to chip away at that last bit, little by little.
After returning to normal, Kaida decided to treat the bandit as a dead body and started paying attention to what Mitsuru was teaching. She cut open the bandit's stomach, removed a piece of the liver, and asked Kaida to regrow it.
Kaida simply used the Healing Palm Jutsu and regrew the liver, which only took him 35 seconds. Mitsuru nodded her head, then cut a section of the bandit's intestines.
This time, Kaida took a full 7 minutes to grow the intestines, and even then, they were not usable.
"What did I do wrong, Sensei?" Kaida asked.
"In reality, nothing. I simply asked you to do the easiest and most difficult tasks side by side without teaching you, just to show you the difference," Mitsuru said.
With tears in his eyes, the bandit thought, 'I should have just killed myself when I got caught by those ninjas. Who knew they were this vicious? And they say I was cruel,' the bandit cried in his heart.
As if Mitsuru could guess his thoughts, she went for his heart next, removing only a small layer so that he wouldn't die and asked Kaida to regrow that. When Kaida did, Mitsuru cut that part once again.
"The cells you grow are normal cells, not the ones required for that specific part. For example, intestines absorb nutrients, and the heart has to pump blood and requires tremendous strength and resilience to do so.
What you did made the cells in that area fragile, which would have resulted in destroying his heart the second his heartbeat rose by even a normal amount," Mitsuru explained.
Just by hearing that, the bandit's heartbeat rose exponentially.
"Then, Sensei, why was I able to restore the liver?" Kaida asked.
"Because the liver has the ability to restore itself over time. When you provided it with healing chakra and nutrients, it actively guided the nutrients to repair itself. Sadly, other body parts don't have this ability, so you will have to learn how to restore each part separately," Mitsuru said.
Kaida nodded, fully ready to devote himself to learning. Mitsuru was pleased to have such a dedicated student, while the bandit cried over his luck, promising any god that would listen that he would be a saint in his next life if he could just die painlessly now. He had no thoughts of escaping from this place at all.
After learning until 4 PM, Kaida was able to restore an intestine a little better than before, but it was going to take time to fully restore the body parts to a normal state.
Mitsuru stopped Kaida and said, "That's enough for now. We'll continue this tomorrow. This is the list of things you should know in fuinjutsu before even thinking about Mitotic Regeneration Jutsu," she said, handing Kaida a piece of paper.
Kaida took the paper and said, "I will try to learn them as soon as I can, Sensei." Mitsuru just nodded her head and left for her office. She was very happy that she didn't have to do any paperwork; otherwise, with how things were going in the village, even using every last bit of chakra to make shadow clones wouldn't have been enough to complete it, just like her coworkers.
Now they were cursing themselves and their luck for ever suggesting that bet (the position of Mitsuru if Kaida didn't become a general practitioner, otherwise they would have to do Mitsuru's paperwork for 3 months. There was still some time before that deadline).
As Mitsuru left, Kaida read the list she had given him:
---
1. *Storage Seals (Chakra Seals):* These seals store chakra, weapons, or other objects in a separate dimensional space. A seal master can create and use these seals to store large amounts of chakra for later use or to carry various tools and weapons without needing physical storage space.
2. *Barrier Seals:* Barrier seals create protective barriers that can block attacks, restrict movement, or seal off areas. A seal master can design barriers to be either permanent or temporary, depending on the situation.
3. *Suppression Seals:* These seals suppress or contain powerful energies, such as chakra from a tailed beast or a curse mark. A seal master can use these seals to control dangerous powers within a person or an object.
4. *Binding Seals:* Binding seals immobilize targets, preventing them from moving or using chakra. A seal master can use these to capture or restrain opponents without causing them harm.
5. *Healing Seals:* Healing seals enhance the body's natural healing process or store healing energy for later use. A seal master could use these in conjunction with medical jutsu to create powerful restorative effects.
6. *Reinforcement Seals:* Reinforcement seals enhance the strength, durability, or efficiency of other seals or physical structures. A seal master could use these to make existing seals more powerful or to reinforce physical objects or barriers.
7. *Curse Seals:* Curse seals impose restrictions or afflictions on a target. A seal master can use these to place powerful curses that can weaken, control, or track others.
8. *Time-Delayed Seals:* These seals are designed to activate after a certain period or under specific conditions. A seal master can create seals that trigger effects like explosions, traps, or healing after a set time.
9. *Complex Array Seals:* These seals are intricate patterns that combine multiple sealing techniques into a single, powerful array. A seal master would be capable of designing and utilizing these arrays for complex tasks, such as large-scale protection or multi-layered traps.

Kaida could easily guess why each of these seals was necessary for learning Mitotic Regeneration Jutsu.
(A.N: I'm sure you can also figure that out. Wow, you guys are as smart as the main character! ^~^)
