Infinite Upgrade Technique of the Heavens

This might be Chen An's first mission to kill someone. When Chen An returned to Konoha Village, his grandfather Hikari Kiyomi and aunt Hikari Mukasa, along with his nephew Hikari Hikari, were all waiting for Chen An to come back home.

"Hey, Xiao An, you're back. How was the mission?"

Seeing Chen An and Hikari Hiroshi coming back, aunt Hikari Mukasa hurriedly stood up and walked forward. Asked

"Hey, aunt, don't you know me yet? The rebel ninja that my uncle chose was killed by me in one strike."

Chen An stood proudly in front of aunt Hikari Mukasa and said with a smile.

"What? You said your uncle chose the mission target and was killed by you in one strike."

Aunt Hikari Mukasa said in surprise when she heard Chen An's words.

"Impossible? I've seen the rebel ninja from the Cloud Village that Hong chose before. Isn't he a subordinate of Kinkaku and Ginkaku? How could he be killed by you in one blow?"

Grandpa Hyuga Qingmu behind my aunt heard Chen An's words and asked in confusion.

"Wife, father-in-law, Xiao An didn't lie. He did kill the rebel ninja from the Cloud Village that I chose in one blow."

Uncle Hyuga Hong, who was standing behind Chen An, was embarrassed to say this to his wife and father-in-law.

"It's actually true. Come on, come on, you two sit down and tell us how you killed that rebel ninja in one blow."

Hearing what uncle Hyuga Hong said, aunt Hyuga Muxia and grandfather Hikami Qingmu looked at each other. They both showed incredible expressions in their eyes, and hurriedly pulled Chen An and uncle Hyuga Hong to sit down, asking the two to explain the process in detail.

In order to convince his wife and father-in-law, Hiroshi Hyuga told his wife and father-in-law in detail about the process of Chen An's battle.

"I didn't expect that the rebel ninja from the Human Cloud Village was actually drunk. He was killed by Xiao An with a Rasengan."

Finally, uncle Hiroshi Hyuga spread his hands helplessly, saying that he had never seen such a stupid rebel ninja.

"So that's how it is. I thought Xiao An was so capable that he killed the opponent with one blow. It turned out that the rebel ninja was drunk."

Hearing the explanation of uncle Hiroshi Hyuga, aunt Hiroshi Muxia breathed a sigh of relief and said to the two people with a smile.

"Xiao An performed well. The first blood-seeing mission was successfully completed. Later, I will find some more missions for you with your uncle. Help you grow up as soon as possible."

Grandpa Hyuga Qingmu did not care about the performance of the rebel ninja. Instead, he was satisfied that Chen An did not vomit or show any incredible performance after killing the rebel ninja, and said to Chen An with a smile.

"Okay, Grandpa, thank you for your help."

Hearing his grandfather's praise, Chen An was not too proud, but nodded slightly and said with a smile.

Afterwards, in order to let Chen An continue to see blood and improve his practical experience.

In the first year, most of Chen An's opponents were at the level of Genin. For Chen An, who mastered most advanced ninjutsu, if these people found him, he would have two moves, one to defeat their defense and one to take their lives. If they hadn't found Chen An, these opponents would basically be killed by Chen An using the Rasengan.

Even after Chen An learned the Thunder Chakra mode, all Genin opponents would be killed by Chen An. The Rasengan with the addition of the lightning attribute will disappear after being thrown out, and will not reappear until it touches the enemy.

In the second year, Grandpa Hinata Qingmu and uncle Hinata Hong began to look for Chunin-level opponents for Chen An.

Because there are very few heavyweight opponents. On average, only one suitable opponent for Chang An can be found every two months.

But it must be said that the Chunin-level ninjas do have rich practical experience. At the beginning, Chen An could not defeat these opponents with either his soft fist or chakra mode. He could only use the Flying Thunder God Technique combined with the Rasengan for sneak attacks to barely defeat these opponents.

In the third year, Chen An's chakra circulation broke through to the second level.

This breakthrough in chakra circulation not only increased Chen An's chakra volume, but also enabled Chen An to successfully fuse the Ice Release Bloodline Genkai. Chunin-level opponents can no longer stop Chen An's soft fist. If the Thunder Release Chakra Mode is added, Chen An can solve all these opponents faster.

If the Ice Release Bloodline Genkai is added, it will be a complete crushing suppression for Chunin-level opponents.

In the fourth year, Grandpa Hyuga Qingmu found opponents for Chen An, basically all of them were from the four major ninja villages.

In order to fight these ninjas, Chen An often needs to hide his soft fist and white eyes.

Can only useLightning Chakra mode and some common attribute ninjutsu as means of fighting.

Because these jonins can escape from the battle with Chen An at any time. Even Chen An himself may be in danger of his life if he doesn't pay attention.

Fortunately, the previous three years have accumulated enough experience for Chen An. Although he couldn't defeat these opponents at the beginning, Chen An, who had the Flying Thunder God Technique, could always use the Flying Thunder God Technique to escape when these people were in the blind spot of vision.

In the fifth year, Chen An was able to tie with the jonins of the four major ninja villages. He even directly injured the jonins of the four major ninja villages. Although he didn't kill them, it was enough for Chen An, who was already 16 years old. After all, Chen An's opponents were basically the elite jonins of the four major ninja villages.

By the sixth year, Chen An could kill the elite jonins of the four major ninja villages within 100 rounds. The premise is that this jonin and Chen An fight to the death.

In the seventh year, Chen An's chakra circulation broke through to the third level and successfully opened the sage mode.

When the elite jonin faced Chen An's offensive, they were crushed by Chen An. With all his strength, Chen An could easily kill these elite jonin.

In seven years, Chen An raised his chakra circulation to the third level and possessed the ice escape blood limit.

Relying on his huge chakra, Chen An can directly freeze a certain range. When other people fight in this area, not only will their blood be frozen, but even their opponent's thoughts will be frozen.

Moreover, with a huge amount of chakra, Chen An's ice escape not only has a wider freezing range than the Mizunotsuki clan, but also a much lower freezing temperature than the Mizunotsuki clan.

It is precisely because of the powerful ice escape that many ninjas who fought against Chen An not only did not think that Chen An was from Konoha Village, but also thought that Chen An was a ninja from the Mist Village, which brought a lot of trouble to the Mist Village.

During these seven years of fighting, not only was Chen An not discovered by the various ninja villages, he also improved his strength. It can be said that ice escape brought great convenience to Chen An.
