Chapter 556: Backup Hidden Chakra Completed

That night, at Tsunade’s house.

Muzuki and Tsunade were in the study, conducting a final check of all the development data for the Yang Seal.

With Lady Tsunade, the Ninja World’s top medical Ninja, assisting him, plus his diligent practice of Sealing Technique, Muzuki was finally close to completing his ‘power bank’ plan.

At this moment, Muzuki was just one final step away from his envisioned Yang Seal: modifying and perfecting the existing Yang Seal within his body, with the theoretical framework already quite complete.

“I’m exhausted, it’s finally over,” Tsunade slumped ungracefully into her chair.

“But it was worth it, wasn’t it? Not only is my Yang Seal perfected, but you’ve also completed the development of Mitotic Regeneration,” Muzuki said with a chuckle, taking a sip of tea.

Tsunade helped Muzuki perfect his Yang Seal, and Muzuki also helped Tsunade complete the development of the Ninjutsu that complements the Yin Seal.

Without Mitotic Regeneration, the Yin Seal was almost useless.

Tsunade rolled her Byakugan, saying irritably, “You make it sound like mutual development and mutual benefit. I wasn’t that desperate to perfect the Yin Seal.”

Tsunade researched the Yin Seal and Mitotic Regeneration purely out of boredom to pass the time, not like Muzuki who wanted to improve his combat power.

Because Tsunade wasn’t planning to go to the battlefield, nor did she want to fight as a Ninja like before; she simply had no need to improve her strength.

If it weren’t for some other wonderful uses of Mitotic Regeneration, Tsunade wouldn’t have bothered researching it.

“You absolutely must make the supper tonight extra lavish! It has to be at least ten times as rich as a normal dinner!” Tsunade reminded him with a serious expression.

In a sense, this might be a farewell meal, and Tsunade had to eat her fill.

It wasn’t that Tsunade was preparing to leave Konoha; Konoha was still in the midst of the war’s Uzumaki, so Tsunade couldn’t easily depart.

It was that she felt her interactions with Muzuki would decrease in the future; at least, him coming to her house to help cook would likely be very rare.

Because the reason Muzuki and Tsunade met was that he wanted to learn knowledge from Tsunade to develop the Yang Seal.

Later, their relationship improved, and plus Muzuki gave her some benefits, so Tsunade helped him develop it together.

Now that the Ninjutsu development was complete, Muzuki no longer needed her as much.

When he wasn’t asking for a favor, Tsunade wasn’t confident she could make Muzuki obediently come to her house to cook.

After all, she was one of the Sannin, and Muzuki was also the renowned Raging Sun Mu Yue, not an ordinary Ninja.

“Okay, once I complete the final step, I’ll go prepare supper. A supper that will definitely satisfy you,” Muzuki nodded.

Developing the Yang Seal was not easy; if it weren’t for Tsunade’s help, he probably would have had to spend a few more years to succeed.

So, let alone preparing a lavish supper, even if Tsunade wanted a Manchu Han Imperial Feast, Muzuki would satisfy her.

The Yang Seal was too important to him, even more important than a perfect-grade skill.

“You said it! Don’t blame me if I make more demands if I’m not satisfied,” Tsunade’s eyes lit up.

“Yes, I said it.”

“Then hurry up and do the final step,” Tsunade urged.

She was already impatient to enjoy the supper that Muzuki said would absolutely satisfy her.

Muzuki was a person who didn’t boast; if he said he could satisfy her, he would definitely put his true skills into making a grand meal.

Actually, even if Tsunade didn’t rush him, Muzuki was already preparing to start. This was a Ninjutsu he had been planning since shortly after his transmigration, and now that it was finally developed, Muzuki’s heart was not as calm as it appeared.

Although the Yang Seal couldn’t increase his upper limit, it could significantly enhance his stamina, which was of great importance to Muzuki.

“Hoo.” Muzuki closed his eyes, adjusted his Breathing Technique, and focused his breathing to the extreme, entering the Transparent World state.

His next operation required very high precision, otherwise, he could easily get injured, and it would be an internal injury, possibly even damaging his Chakra circulatory system if severe.

This was also why Muzuki wanted to perform it next to Tsunade; even if an accident occurred, Tsunade, the Ninja World’s top healer, would be there to treat him.

The Yang Seal before its perfection was like the Yin Seal without Mitotic Regeneration; it wasn’t entirely useless, but it might only be useful in specific situations, which were generally unlikely to occur.

Of course, that was for ordinary Ninja; it actually had a considerable effect on Muzuki.

Because before its complete perfection, Muzuki also had a small breakthrough, allowing it to be applied to Shadow Clone, and then constantly release a small amount of Chakra to maintain the Shadow Clone, solving the Shadow Clone’s duration problem and making Muzuki’s multi-tasking easier.

The perfection of the Yang Seal was essentially similar to the Yin Seal’s Mitotic Regeneration.

However, the actual effects were different; the Yin Seal provided automatic healing and enhanced strength, while the Yang Seal was bound by Muzuki to the Breathing Technique Chakra Mode.

As long as the Yang Seal within his body was updated, Muzuki would essentially have an additional Chakra pool, though this pool could only be used for a specific Breathing Technique Chakra Mode.

“Flame Breathing, for now. Fire Release is still the strongest,” Muzuki chose Flame Breathing.

There were significant differences between different Breathing Techniques, so the current Yang Seal only supported a single Breathing Technique Chakra Mode and could not be compatible with all Breathing Technique Chakra Modes.

However, it didn’t have much impact on Muzuki; if he encountered an enemy that required switching Breathing Techniques, he could just turn off the Yang Seal.

After all, this wasn’t like the Eight Gates’ Gate of Death, which couldn’t be closed once opened.

Once Muzuki completed everything, he began to refine Chakra and inject it into the Yang Seal.

When the Chakra accumulated to a certain amount, Muzuki stopped refining Chakra and opened his eyes. A flame-shaped mark slowly appeared on his forehead.

“It succeeded?” Tsunade asked, looking at the calm Muzuki.

She didn’t have abilities like the Byakugan or Transparent World, so she could only rely on experience to determine if Muzuki had succeeded or failed.

“It should have succeeded,” Muzuki replied after sensing the Yang Seal.

Originally, the Yang Seal in Muzuki’s body could also store and release Chakra.

Storing was fine; there was no problem as long as it didn’t exceed a certain amount. But releasing Chakra was a big problem; even a little too much could easily cause Chakra confusion.

Now it was different; just now, Muzuki tried to use the Chakra inside the Yang Seal, and the Chakra inside the Yang Seal remained perfectly still.

This was the difference in the perfected Yang Seal; Yang Seal Release was essentially equivalent to entering the Breathing Technique Chakra Mode. Outside of the Breathing Technique Chakra Mode, the Chakra inside the Yang Seal only went in and did not come out.

“Let me check,” Tsunade stood up and walked to Muzuki’s side, directly reaching out and touching several important Chakra points related to the Yang Seal.

“It’s perfect,” Tsunade commented.

Even if Tsunade did it herself, she wasn’t confident she could achieve what Muzuki did; this was an operation performed inside the human body.

“Once I’ve accumulated enough Chakra, I’ll enter Flame Breathing Chakra Mode to test it. If there are no problems, I’ll teach it to Kakashi,” Muzuki thought to himself.

Muzuki naturally wanted to teach such a good Ninjutsu as the Yang Seal to his disciples.

His disciples were all heavy Chakra users, their potential limited by their age and physical condition.

Except for Might Guy, who had the Eight Gates, all other disciples who could learn the Yang Seal would see significant improvement.

However, currently, Muzuki only planned to teach it to Kakashi.

Because the revised Yang Seal had a prerequisite for learning: extremely high precision in internal Chakra control.

If this condition couldn’t be met, learning the Yang Seal would be self-mutilation.

This was why Tsunade and Jiraiya had both advised Muzuki not to waste time on the Yang Seal; Muzuki’s concept for developing the Yang Seal didn’t seem like something a human could master.

Only Kakashi, who also possessed the Transparent World, would be able to successfully master Muzuki’s Yang Seal.

As for the remaining disciples, Muzuki had no choice but to wait until they also mastered Transparent World, or until Muzuki had a further breakthrough with the Yang Seal, lowering its difficulty.

“Since it’s done, hurry up and prepare supper!” Tsunade urged, patting Muzuki’s shoulder.

She was already impatient for supper time.

“If you’re hungry, I can send a Shadow Clone back to get some pastries to tide you over; preparing supper will take a long time,” Muzuki reminded her.

Although he had culinary skills, this didn’t mean all of Muzuki’s dishes were of the same quality.

The more effort and care Muzuki put into cooking, the better the final dish would taste.

Tsunade had helped Muzuki a great deal, so Muzuki naturally wouldn’t be stingy with his time and would do his best to make the most delicious meal.

Tsunade initially wanted to agree, but then she thought, if she ate pastries now, she would eat less supper later.

While Muzuki’s pastries were delicious, a grand meal clearly appealed more to Tsunade.

“Go get them,” Tsunade still agreed.

Because she could save them for tomorrow, or give them to Shizune, which would mean Shizune would eat a little less supper.

Muzuki formed a hand seal, creating a Shadow Clone, while his main body began preparing supper. The Shadow Clone returned to his home in the Main urban area.

Muzuki had already prepared the necessary ingredients. He skillfully entered the kitchen and quickly began processing the various ingredients.

The sounds of Muzuki cooking were heard by Shizune, who was reading.

“Teacher Muzuki, let me help,” Shizune walked out of her room and into the kitchen, offering to help.

Shizune was not one to freeload.

“No need, I can handle it myself,” Muzuki politely declined.

Shizune hesitated for a moment, and seeing Muzuki’s firm attitude, she finally nodded and returned to the living room.

Seeing Tsunade lying on the sofa, Shizune felt both annoyed and helpless.

This house was neither hers nor Muzuki’s; it was Tsunade’s.

Yet, Muzuki was cooking in the kitchen, while Tsunade, instead of helping, was sprawled out in the living room.

“Lady Tsunade, honestly, why are you making Teacher Muzuki cook supper so late?” Shizune couldn’t help but complain.

Shizune believed that Tsunade must have demanded supper, and Muzuki reluctantly agreed.

Seeing such a kind Teacher Muzuki being exploited by Tsunade, Shizune felt deeply sorry for him.

Although Tsunade had shown great kindness to Shizune, Muzuki had also been Shizune’s teacher for a considerable time, so this time, Shizune sided with Muzuki.

“If I wanted to eat, I could just make it myself.”

Tsunade sat up and grabbed Shizune’s fair, soft face, kneading it.

“It’s all your fault, Shizune! If your cooking was as delicious as Muzuki’s, would I even need to ask him to cook?” Tsunade said self-righteously.

Shizune was speechless. It really was a shame that her cooking wasn’t as delicious as Teacher Muzuki’s.

If Tsunade had used someone else as an example, Shizune would have reflected internally, but Muzuki’s culinary skill was like a towering mountain whose peak Shizune couldn’t see; she truly had the will but lacked the ability.

“But it’s fine, I’m a big person, so I’ll forgive you,” Tsunade said with a generous air.

Shizune was about to say thank you, but then she thought, she hadn’t done anything wrong either. So she took out her medical books from the room and sat next to Tsunade to read.

She didn’t have Tsunade’s talent, so she needed to work harder to grasp Tsunade’s teachings.

In terms of perseverance and willpower, Shizune could surpass many Ninja in Konoha.

After all, she had been following Tsunade, who was in a state of slacking off, from the very beginning. Yet, Shizune not only didn’t slack off with Tsunade but also strove for self-improvement, which showed her remarkable mindset.

Not long after, the Shadow Clone delivered the pastries.

Tsunade took the pastries, smiled, and handed them to Shizune, saying:

“Your favorite, Muzuki’s secret pastries. Don’t eat them all, though; you have to leave at least half for me.”

Shizune looked at Tsunade in surprise. In the past, Tsunade would always eat a lot herself before remembering her. What was going on today?

Shizune reached out a little worriedly and touched Tsunade’s forehead, showing a puzzled expression, “It’s not hot, either.”

Tsunade looked at Shizune with a face full of black lines. What had her image become in Shizune’s mind?

“Hmph, so that’s how you see me, Shizune,” Tsunade said, crossing her arms with an unhappy expression.

Shizune put down her book, her expression a bit awkward.

There was no harm without comparison. Compared to a perfect teacher like Muzuki, Tsunade, who often got drunk, gambled all her money away, and needed a child like her to take care of her, was really unreliable.

“Lady Tsunade, I’m sorry,” Shizune apologized sincerely.

But Tsunade’s expression remained unchanged.

Shizune stood up and walked behind the sofa to give Tsunade a shoulder massage and back rub. Only then did Tsunade’s expression soften.

“I wronged Lady Tsunade. Although she’s not as perfect as Teacher Muzuki, Lady Tsunade also takes good care of me.” Shizune, who had finished serving Tsunade, ate Muzuki’s pastries with a blissful expression.

Due to her apology to Tsunade, Shizune didn’t eat half; she only ate a third, intending to leave the rest for Tsunade.

“All the dishes are ready.”

After a long wait, Muzuki brought out dish after dish.

There were many excellent dishes from Muzuki’s previous life, both visually appealing and delicious, as well as some local dishes from the Ninja World, emphasizing variety and abundance.

Looking at the plates of food that almost couldn’t fit on the dining table, Tsunade gave Muzuki a thumbs-up, then quickly washed her hands and started eating.

Even Shizune couldn’t maintain her image in front of Muzuki and began an immersive eating experience.

When Shizune really couldn’t eat anymore, she regretfully put down her chopsticks, and then, remembering something, she looked at Tsunade with a resentful expression.

“Lady Tsunade, you are truly despicable.”

“This is the adult world,” Tsunade sighed inwardly, then continued her immersive eating.

After this meal, she didn’t know when she would eat Muzuki’s cooking again.

Should she proactively freeload?
