Infinite Upgrade Technique of the Heavens

When Tsunade Senju opened the medical ninjutsu scroll, she found the S-level medical ninjutsu created by Chen An, Ninjutsu·Creation Regeneration·Hundred Healings Technique.

This ninjutsu relies on the powerful recovery ability of the sage body, especially the descendants of the senju who have the ancestor body like Tsunade Senju.

You should know that Tsunade Senju not only has the sage body of the Senju clan, but also the sage body of the Uzumaki clan from Mito Uzumaki.

So Tsunade Senju is far superior to other ordinary ninjas in terms of lifespan and chakra.

"No wonder grandma is willing to give away two S-level ninjutsu. The medical ninjutsu created by Hyuga Rin is too powerful."

Tsunade Senju looked at the medical ninjutsu scroll in surprise and said to herself.

The next day, Mito Uzumaki came to the Hyuga clan with the summoning scroll of Shigulin and the ninjutsu scroll of Flying Thunder God Technique, looking for Chen An who had just returned to the Hyuga family.

"Mister Mito, for such a small matter as delivering the ninjutsu scroll, can't you just send Tsunade? It's a bother for you to make an extra trip."

Grandpa Hyuga Kiyomura said to Uzumaki Mito with a smile, bringing Chen An.

"Kingmu, it's not a big deal. I just came here to take a look because I was curious."

Uzumaki Mito said to Grandpa Hyuga Kiyomura with a smile.

But Uzumaki Mito's perception and gaze have always been on Chen An who was sitting next to him.

Through his perception, Uzumaki Mito had to be surprised. As a member of the Hyuga, Chen An's sage body has actually reached a very advanced level.

Although not as good as her husband, Hashirama Senju, Chen An's sage body is already the first person under Hashirama Senju.

Even her brother-in-law, Tobirama Senju, his sage body is not as strong as Chen An's sage body.

Chen An's sage body not only gives people a feeling of majestic chakra, but also has a terrifying vitality.

Chen An, who was standing by, knew that Mitsu Uzumaki had misunderstood when he saw Mitsu Uzumaki's expression.

The level of his immortal body was not actually high. The reason why it was so vigorous was because of the chakra circulation technique he practiced.

In the cycle after cycle, not only Chen An's chakra was strengthened and re-transformed, but also Chen An's vitality was improved.

After all, the biggest feature of Yang escape chakra is its vigorous vitality.

But Chen An didn't want to explain anything. Mitsu Uzumaki had misunderstood. It was better than revealing his own secret.

"Xiao An, this is what you need. I'll give it to you now. But the summoning scroll of the Corpse Bone Spirit must be handed over to the Slug Immortal after you sign it."

"After all, this is a summoning scroll unique to the Corpse Bone Forest Holy Land."

Mitsu Uzumaki handed the scroll to Chen An and said to him with a smile.

"Okay, Lord Shuiku, I got it. After signing the contract, I will study it for a maximum of one month, and I will hand it over directly to the Slug Sage after the study."

Chen An took the two scrolls and said to Uzumaki Mito with a smile.

"Okay, the things have been delivered, and I will go back."

Seeing that Chen An had put away all the scrolls, Uzumaki Mito stood up and said to Grandpa Hyuga Qingmu.

"Thank you very much, Lord Mito. I'm sorry to bother you to come and deliver things again."

Grandpa Hyuga Qingmu stood up, and Chen An sent Uzumaki Mito to the gate, and watched Uzumaki Mito leave.

"Xiao An, why did you think of exchanging the summoning scroll with Tsunade? What are you going to study this time?"

After returning home, Grandpa Hyuga Qingmu saw Chen An holding the summoning scroll of the Corpse Cave and studying it non-stop, and walked up to him curiously and asked Chen An.

"Grandpa, I want to use the summoning scroll to research a special ninjutsu that can allow the entire Hyuga clan to use summoning."

Chen An told his grandfather about his idea.

To put it simply, it is to set up a time and space teleportation point for the summoning scroll in the Hyuga clan.

After the Senju clan signed the summoning contract, they can use the reverse summoning technique as long as they encounter a life-and-death crisis and return to this time and space teleportation point anytime and anywhere

"So that's how it is. Then you study it carefully."

Hearing Chen An's words, Grandpa Hyuga Qingmu shook his head with a smile and said to Chen An with a smile.

His grandson is really full of wonderful ideas. He actually came up with this way to ensure the safety of the members of the Hyuga clan.

After Grandpa Hyuga Qingmu left, Chen An began to carefully study the seal scroll of the Wet Bone Forest.

As one of the three holy places for summoners, the Wet Bone Forest is still a bit of a thing to be honest. The runes on this summoning scroll alone are extremely complex.

Chen An carefully copied all the runes on the scroll of the Corpse Forest Spiritual Holy Land and engraved them on the blank scroll next to it.Chen An discovered that all the summoning holy places actually use blood as the foundation for summoning.

If Chen An uses his own blood to construct this summoning scroll, then it is very likely that he will have to stay in a safe place inside Konoha Village.

Among the three holy places, whether it is the White Snake Immortal, Mr. Big Toad, or the Slug Immortal of the Stone Drum Forest. Their bodies have actually always been in their summoning holy places and have never left.

No matter how much chakra the summoner pays, their bodies will not go out.

Because once they go out, when they use the reverse summoning technique again, they will appear directly next to the three great immortals.

And after they are summoned out, they can only walk back slowly.

Helplessly, Chen An had to put down the summoning scroll in his hand.

Fortunately, he had kept a careful eye before and specifically asked for the Flying Thunder God Technique.

Although the entry level of Flying Thunder God Technique is very high, Chen An can find a way to combine the space mark inside with the spiritual scroll.

However, Chen An was not in a hurry to open the Flying Thunder God Technique, but wrote his name Hinata Rin on the scroll of Wet Bone Forest.

"Spiritual Technique!"

Chen An directly used very little chakra to perform the spiritual technique.

"Are you the new contractor? Please teach me."

The slug immortal who was summoned said to Chen An in a soft voice.

"Slug immortal, please teach me."

Chen An said to the slug immortal with a smile.

"By the way, slug immortal, can I learn the immortal technique possessed by Wet Bone Forest? "

Chen An asked the Slug Sage with a smile.

"Well, you can learn it. You have a sage body of a high level, and the amount of chakra is also sufficient."

The Slug Sage felt the chakra in Chen An's body and said to Chang An with joy.

"Then Slug Sage, does the Wet Bone Forest have a white-stimulated technique like the Ryuchidong, or an inorganic reincarnation technique?"

Chang An asked the Slug Sage curiously.

"No, the greatest ability of the Wet Bone Forest's sage technique is that it can enter the sage mode faster, and it can conquer a person's vitality and recovery ability."

The Slug Sage shook his head and said in a flat voice.

"Oh, is that so. "

Chen An's original excited expression disappeared immediately. After all, his chakra circulation reached the third level, which was a permanent sage mode.

"Then Slug Sage, you go back first. I will go to your place to study after I finish my research."

Chen An said to Slug Sage in a flat tone.

Then he lifted the summoning technique and let Slug Sage go back.
