Ninja school teacher, I can become stronger by teaching.

Chapter 556: Backup Hidden Chakra Completed

Night, Tsunade's house.

Mu Yue and Tsunade were in the study room doing a final check on the development data of the Yang Seal.

With the assistance of Tsunade, the top medical ninja in the ninja world, and his hard work in learning and practicing sealing techniques, Mu Yue is finally about to complete his power bank plan.

At this moment, Mu Yue is only one step away from achieving the Yang Seal he envisioned, which is to modify and improve the Yang Seal already in his body. The specific theory is already very complete.

"I'm so tired, it's finally over." Tsunade slumped in the chair without any image.

"But it's worth it, isn't it? Not only has my Yang Seal been perfected, but you've also completed the development of the Hundred Healing Techniques." Mu Yue smiled and picked up the teacup and took a sip.

Tsunade helped Mu Yue perfect the Yang Seal, and Mu Yue also helped Tsunade complete the development of the Yin Seal's supporting ninjutsu.

Without the Hundred Heroes Technique, the Yin Seal is of little use.

Tsunade rolled her eyes and said unhappily, "You make it sound like it's a matter of mutual development and mutual benefit. I'm not that eager to perfect the Yin Seal."

Tsunade studied the Yin Sealing Hundred Healings Technique purely to kill time out of boredom, not because she wanted to improve her combat power like Mu Yue did.

Because Tsunade was not planning to go to the battlefield, nor did she want to fight as a ninja like before, she had no need to improve her strength at all.

If the Hundred Healings Technique didn't have some other magical uses, Tsunade wouldn't have bothered to study it.

"You have to make this midnight snack more substantial. It must be at least ten times more substantial than our usual dinner!" Tsunade reminded seriously.

In a sense, this might be a farewell dinner, and Tsunade must have a good meal.

It’s not that Tsunade is planning to leave Konoha. Konoha is still in the vortex of war, so it’s not easy for Tsunade to leave.

She felt that she would have less interactions with Mu Yue in the future, and at least it would be difficult for her to come to her house to help with cooking.

The reason why Mu Yue met Tsunade was that he wanted to learn knowledge from Tsunade and then develop the Yang Seal.

Later, their relationship improved, and with some benefits from Mu Yue, Tsunade started to help with the development.

Now that the ninjutsu has been developed, Mu Yue no longer needs her that much.

Unless she needed a favor, Tsunade didn't have the confidence that she could get Mu Yue to come to her house and cook.

After all, she is one of the three ninjas, and Mu Yue is also the famous Lieyang Mu Yue, not an ordinary ninja.

"Okay, I'll prepare a midnight snack after I finish the last step. It will definitely satisfy you." Mu Yue nodded.

Developing the Yang Seal was no easy task, and if it weren't for Tsunade's help, it would probably take him several years to succeed.

So let alone making a sumptuous midnight snack, even if Tsunade wanted to have a full banquet, Mu Yue would satisfy her.

The Yang Seal is very important to him, even more important than a perfect-level skill.

"You said it, so don't blame me for making more demands if you're not satisfied." Tsunade's eyes lit up.

"Yeah, that's what I said."

"Then hurry up and take the last step." Tsunade urged.

She couldn't wait to enjoy Mu Yuezhong's midnight snack, which would definitely satisfy her.

Mu Yue is a person who doesn’t brag. If you want to make her satisfied, you must show your real skills in cooking a great meal.

In fact, even if Tsunade hadn't urged him, Mu Yue was ready to start. This was a ninjutsu that he had started planning not long after he traveled through time. Now that it had finally been developed, Mu Yue's heart was not as calm as he appeared.

Although the Yang Seal cannot increase his upper limit, it can increase his endurance, which is of great significance to Mu Yue.

"Huh." Mu Yue closed her eyes and adjusted her breathing, concentrating her breathing to the extreme and entering a state of seeing the world clearly.

His next operation requires very high precision, otherwise he will easily get injured, and the injury will be internal. In serious cases, it may even damage the chakra meridian system.

This is also the reason why Mu Yue had to do the operation next to Tsunade. Even if something unexpected happened, there would be Tsunade, the number one nurse in the ninja world, to treat her.

The Yang Seal before perfection is just like the Yin Seal without the Hundred Healings Technique. It cannot be said to be completely useless. It can only be said that it might be useful, but generally speaking, this possibility is not very likely.

Of course, that is for ordinary ninjas, but it actually has a significant effect on Mu Yue.

Because before it was completely perfected, Mu Yue also had a small breakthrough, which allowed him to act on the shadow clone, and then release a small amount of chakra at all times to maintain the shadow clone, solving the problem of the shadow clone's existence time and making Mu Yue's multi-line operations easier.

The perfection of the Yang Seal is actually similar in nature to the Yin Seal's Hundred Heroes Technique.

But the actual effects are different. The Yin Seal automatically heals and enhances strength, while the Yang Seal is bound to Mu Yue's breathing chakra mode.

As long as the version of the Yang Seal in the body is replaced, Mu Yue will have an extra chakra pool in the future, but this pool can only be used to use a certain breathing chakra mode.

"Let's use Breathing of Fire. Fire Style is still the strongest right now." Mu Yue chose Breathing of Fire.

There are significant differences between different breathing methods, so the current Yang Seal only supports a single breathing method chakra mode and is not compatible with all breathing method chakra modes.

However, it did not have much impact on Mu Yue. When encountering an enemy that required switching breathing methods to deal with, she would just turn off the Yang Seal.

After all, this is not the Death Gate of the Eight Gates of Ninjutsu. Once it is opened, it cannot be closed.

When Mu Yue finished everything, he began to refine the chakra and inject it into the Yang Seal.

When the chakra accumulated to a certain amount, Mu Yue stopped refining the chakra and opened his eyes. A mark shaped like a flame slowly appeared on his forehead.

"Successful?" Tsunade asked, looking at Mu Yue, whose breath was calm.

She doesn't have the ability to roll her eyes or see through the world, so she can only rely on experience to judge whether Mu Yue is successful or not.

"It should have succeeded." Mu Yue felt the Yang Seal and replied.

It turns out that the Yang Seal in Mu Yue's body can also store and release chakra.

Storing is fine as long as the amount does not exceed a certain level, but releasing chakra is a big problem. A little more will easily cause chakra confusion.

It’s different now. Just now, Mu Yue tried to use the chakra inside the Yang Seal, but the chakra inside the Yang Seal did not move at all.

This is the difference of the Yang Seal after it is perfected. The Yang Seal: Unlocking is actually equivalent to entering the Breathing Chakra Mode. In the non-Breathing Chakra Mode, the chakra inside the Yang Seal can only enter but not exit.

"Let me check it out." Tsunade stood up and walked to Mu Yue's side. She reached out and touched several important chakra points related to the Yang Seal.

"Perfect," Tsunade commented.

Even if Tsunade did it herself, she didn't have the confidence to be able to do it like Mu Yue, as this involves operating inside the human body.

"Once I have accumulated enough chakra, I will enter the Flame Breathing Chakra mode to test it. If there is no problem, I will teach it to Kakashi." Mu Yue thought to herself.

Mu Yue certainly wanted to teach his disciples such a good ninjutsu as Yang Fengyin.

Each of his disciples is a big consumer of chakra, as their performance is limited by their age and physical condition.

Except for Might Guy who has the Eight Gates, the rest of the disciples who can learn the Yang Seal will have significant improvements.

But for now, Mu Yue is only planning to teach Kakashi.

Because the revised Yang Seal has a prerequisite for learning, which is extremely high accuracy in controlling the chakra in the body.

If this condition cannot be met, learning the Yang Seal is equivalent to self-harm. This is why Tsunade and Jiraiya both advised Mu Yue not to waste time on the Yang Seal. Mu Yue's intention in developing the Yang Seal is not something that a human can practice.

Only Kakashi, who has also mastered the transparent world, could successfully practice Mu Yue's Yang Seal.

As for the remaining disciples, Mu Yue had no choice but to wait for them to master the transparent world, or for Mu Yue to make further breakthroughs in the Yang Seal, thus reducing the difficulty.

"Now that it's done, let's prepare the midnight snack!" Tsunade urged, patting Mu Yue's shoulder.

She was already thinking about fast approaching supper time.

"If you're hungry, I'll ask my shadow clone to go back and get some pastries to fill your stomach. It will take a long time to prepare the midnight snack." Mu Yue reminded.

Although she has chef skills, it doesn’t mean that all of Mu Yue’s dishes are of the same quality.

The more carefully and seriously Mu Yue puts into cooking, the better the food will taste.

Tsunade helped Mu Yue a lot, so Mu Yue naturally would not be stingy with time and would try her best to make the most delicious food.

Tsunade wanted to agree, but then she thought that if she ate the pastries, she would have to eat less for the midnight snack later.

Although Mu Yue's pastries were delicious, it was obvious that the feast was more appealing to Tsunade.

"Go get it." Tsunade agreed.

Because she can save it for tomorrow, or give it to Jingyin, so that Jingyin will eat less for midnight snack.

Mu Yue formed a seal to create a shadow clone, and the real body began to prepare a midnight snack, while the shadow clone returned to his home in the main city.

Mu Yue had already prepared the necessary materials. She walked into the kitchen with great skill and began to process the materials quickly.

The noise of Mu Yue cooking was heard by Jingyin who was reading a book.

"Teacher Muyue, let me help." Jingyin walked out of the room and went to the kitchen and said proactively.

Shizune is not a person who likes to eat plain rice.

"No need, just leave it to me." Mu Yue declined.

Jingyin hesitated for a while, and seeing Mu Yue's firm attitude, she finally nodded and returned to the living room.

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

This house is neither hers nor Mu Yue's, it belongs to Tsunade.

As a result, Mu Yue was cooking in the kitchen, and Tsunade didn't help but lay dead in the living room.

"Lady Tsunade, you are such a fool. Why do you still need Teacher Mu Yue to make a midnight snack so late at night?" Shizune couldn't help but complain.

Shizune felt that it must be Tsunade who took the initiative to ask for a midnight snack, and Mu Yue had no choice but to agree.

Seeing such a good teacher Mu Yue being exploited by Tsunade, Shizune felt very sorry.

Although Tsunade was very kind to Shizune, Mu Yue had also been Shizune's teacher for quite some time, so this time Shizune stood on Mu Yue's side.

"If you want to eat, I can cook it."

Tsunade sat up and grabbed Shizune's fair little face with both hands and rubbed it.

"It's all your fault, Shizune. If your cooking could be as delicious as Muyue's, would I still need to ask him to cook?" Tsunade said righteously.

Jingyin was speechless. She felt really sorry that the food was not as delicious as Teacher Mu Yue’s.

If Tsunade used other people as examples, Shizune would reflect on herself inwardly, but Mu Yue's cooking skills were like a mountain that Shizune could not reach the top of, and she was really powerless.

"But it's okay. I'm a magnanimous person and I'll forgive you." Tsunade said generously.

Shizune was about to say thank you, but then she realized that she was not wrong, so she took out the medical books in the room and sat next to Tsunade to read.

She doesn't have the same talent as Tsunade, so she needs to work harder to understand Tsunade's teachings.

In terms of perseverance and determination, Shizune can surpass many ninjas in Konoha.

After all, she had been following Tsunade, who was in a bad state from the very beginning, but Shizune not only did not follow Tsunade in giving up, but also worked hard to improve herself, which shows her mentality.

Not long after, the shadow clone brought the pastries over.

Tsunade handed the pastry to Shizune with a smile and said:

"Don't eat all of your favorite Mu Yue secret pastry. At least leave half for me."

Shizune looked at Tsunade in surprise. In the past, Tsunade would eat a lot before she would think of her, so what happened today?

Shizune reached out and touched Tsunade's forehead with some concern, revealing a puzzled expression, "It's not hot."

Tsunade looked at Shizune with a frown on her face. What kind of image did she have in Shizune's mind?

"Hmph, so that's how you look at me, Shizune." Tsunade crossed her arms and looked unhappy.

Shizune put the book down, looking a little embarrassed.

There is no harm without comparison. Compared with a perfect teacher like Mu Yue, Tsunade, who often stays out drunk, loses all her money in the casino, and needs a little kid like her to take care of her, is really unreliable.

"Tsunade-sama, I'm sorry," Shizune apologized sincerely.

But Tsunade's expression remained unchanged.

Shizune got up and walked to the sofa to massage Tsunade's shoulders and back, and Tsunade's expression finally eased.

"I've wronged Lady Tsunade. Although I'm not as perfect as Teacher Mu Yue, Lady Tsunade also takes good care of me." After serving Tsunade, Shizune ate Mu Yue's pastries with a happy expression.

Because of her feeling sorry for Tsunade, Shizune didn't eat half of it, but only ate one third of it, and prepared to leave the rest for Tsunade.

"The dishes are all ready."

After a long wait, Mu Yue brought out the dishes one by one.

There are not only many excellent dishes from Mu Yue’s previous life that are both beautiful and delicious, but also some local dishes from Naruto. The main feature is richness and variety.

Looking at the plates of food that were almost full on the dining table, Tsunade gave Mu Yue a thumbs up, then quickly washed her hands and started working.

Even Jingyin couldn't maintain her image in front of Mu Yue and started to immerse herself in eating.

When Shizune really couldn't eat anymore, she put down her chopsticks with a look of regret. Then Shizune remembered something and looked at Tsunade with a resentful look.

Lady Tsunade, you are so despicable.

"This is the adult world." Tsunade sighed in her heart, and then continued to eat her meal in immersion.

After this meal, I don’t know when I will eat Mu Yue’s cooking next time.

How about offering to eat for free?

PS: Staying up late has backfired, there may be a lot of typos, if you see them, you can leave a message in this paragraph, I will correct them when I see them.
