Infinite Upgrade Technique of the Heavens

"Good day, you are too much. You didn't tell me in advance, and made me embarrassed in public."

Tsunade Senju, who had changed her clothes, complained to Chen An while walking towards the training ground.

"Can you blame me? You asked me to teach you just because you disagreed with me. If I hadn't reminded you in advance, you would have walked to the training ground now. How many people would laugh at you?"

Chen An looked at Tsunade Senju speechlessly and said helplessly.

"Good day, Tsunade, what are you going to do?"

Just when Chen An and Tsunade Senju were heading to the training ground, Orochimaru and Jiraiya actually came towards them.

"I have created a new unprinted ninjutsu and want to give it to Tsunade. Orochimaru, Jiraiya, you guys come too."

Looking at Jiraiya and Orochimaru, Chen An invited them with a smile.

"Unprinted ninjutsu, really?"

Orochimaru heard Chen An's words and asked Chen An in surprise.

"Yes, this guy has created an A-level unprinted ninjutsu. I'm going to learn from her."

Tsunade stood beside Chen An, patted Chen An's shoulder and said with a smile.

"Give it to us too? Then we'll go too."

Jiraiya said to Chen An with a smile on his face.

"Of course it's just an A-level ninjutsu. We're good friends."

Chen An didn't intend to hide anything from Jiraiya and Orochimaru, but invited them warmly.

"Okay, okay, let's go, go."

Orochimaru and Jiraiya followed Chen An and Tsunade Senju, and the group quickly walked towards the training ground.

After arriving at the training ground, Chen An began to show Tsunade Senju, Orochimaru, and Jiraiya the Rasengan he developed.

"This is the Rasengan I developed. It is the ultimate change of chakra form and belongs to the A-level ninjutsu."

"If you add chakra nature change to this ninjutsu, you can reach the level of S-level ninjutsu."

"But there is another way, that is to release more chakra to make the Rasengan bigger, which can also become the power of S-level ninjutsu."

Chen An said proudly to the three people, Tsunade and Senju.

"Really? Then Chen An, have you added nature change to it?"

Jiraiya asked Chen An curiously.

"Not yet, because if you want to add nature change to it, the best attribute change is wind attribute. But that requires a very high chakra control ability, so it is best to practice the Sage Mode, so that you can ensure that you will not be hurt by the extreme nature change."

Chen An shook his head, indicating that he did not inject chakra nature change into it.

And told the three people the dangers and solutions of injecting chakra nature change into it.

After all, the three people in front of him will correspond to the three major spiritual tree holy places in the ninja world in the future.

They all have their own summoning techniques and matching Sage Mode.

"Ah, wind attribute, I don't have wind attribute chakra."

Hearing Chen An say that the chakra attribute that best fits the Rasengan is the wind attribute, Senju Tsunade was surprised and said.

"Ah, you don't have wind attribute, Tsunade."

At this time, Chen An was surprised to remember that Senju Tsunade did not have wind attribute chakra. Although she was also a sage body, Senju Tsunade had only five chakra attributes, among which the lacked were wind attribute chakra and yin attribute chakra.

"Well, Tsunade, it seems that you can only develop in the direction of the Big Ball Rasengan. But it's okay, after all, the Senju clan and the Uzumaki clan both have the blood limit of the sage body, and the most important feature is that they have strong vitality and a lot of chakra."

"Just concentrate on practicing the strange punch, medical ninjutsu and Big Ball Rasengan."

After knowing that Senju Tsunade did not have wind attribute chakra, Chen An could only shake his head helplessly and said to Senju Tsunade with a smile.

However, Chen An just remembered at this time that he didn't seem to have tested what his chakra attributes were. It seems that after completing the teaching today, he has to find a way to test what his chakra attributes are.

Although he has a sage body and white eyes, he should have chakras of yin and yang attributes. But it is not clear whether the five chakra attributes of wind, thunder, water, fire and earth are missing like Tsunade.

"Come on, this is your training equipment, watch me use it."

Chang An took out a sealing scroll and took out the water ball, leather ball, and balloon that he prepared yesterday.

Although the balloon was a little surprised to see the water ball and leather ball that Chen An took out, Jiraiya and Orochimaru didn't say much, but just watched Chen An demonstrate seriously.

"First, you have to let the rotating's chakra burst the water ball. "

Chen An picked up a water ball and demonstrated it to Orochimaru, Jiraiya and the other two.

"It's very simple, watch me, I can definitely do it in one go."

Seeing Chen An burst the water ball easily. Jiraiya confidently picked up a water ball and said to Chen An.

But things were not as easy as Jiraiya imagined. Among the three, Jiraiya's chakra control was the worst.

So the first one to burst the water ball was Tsunade Senju, followed by Orochimaru, and finally Jiraiya.

"Ah, this ninjutsu consumes a lot of chakra."

Finally completing the first stage, Jiraiya collapsed on the ground, wiped the sweat from his forehead, and said to Chen An very tiredly.

"Yes, this is the possible disadvantage of the Rasengan. Although it is very convenient and the attack is very concealed, the disadvantage is that people with too little chakra may not be able to use it, and even if they use it, they can only use it a few times. "

Chen An said to Jiraiya with a smile on his face.

"But this ninjutsu can be used as a means of counterattack at a critical moment, so it is better to learn it."

Orochimaru keenly sensed the extraordinaryness of the Rasengan and said to Jiraiya with a smile.

"I will tell you the remaining two stages. You can go back and practice slowly."

Seeing that the sun had risen, Chen An said to Senju Tsunade and the other two with a smile.

"There are three stages in the Rasengan. The first stage is the rotation you just practiced. He can practice directly after climbing a tree and stepping on water."

"The second stage is power. The rotation that can only break the water ball is not powerful enough. It cannot be used to defeat the enemy, so in the second stage, what you have to break is not a water ball, but a leather ball."

"After being able to break the leather ball, the power is enough. But the existence time is not long, the third stage is maintenance. Balloons are needed. In this stage, the goal is not to burst the balloons, but to make the rotating chakra form a ball inside the balloons without bursting them. "

Chen An demonstrated the three stages of practice. Seeing this, the three people, Tsunade and Senju, nodded repeatedly.

"You all know it now, right?"

Chen An asked Tsunade and Senju with a smile.

"Yes, yes, I know it, I know it."

Jiraiya said to Chen An with a smile.

"Then you can practice first, I'll go back first."

Chen An smiled and waved to the three people, and left the training ground.
