After eating the Heat-Heat Fruit, my Fire Style is invincible

Then a little calculation shows that Uchiha Huanghuo's digestive power is more than 100 times stronger than that of ordinary ninjas.

Then Huanghuo carefully sensed the changes in his body and found that the sealing technique of Liuku Xianzei can be combined with the breathing of fire.

The energy of the food eaten by Liuku Xianzei can be absorbed by the full concentration breathing mode of the breathing of fire without any waste.

This is equivalent to strengthening the mode of breathing of fire. Such a seamless connection makes Huanghuo very satisfied.

This shows that Huanghuo's strength will increase faster.

"Wait, Breathing of Fire belongs to the respiratory system, and Six Treasury Immortal Thieves belongs to the digestive system, so will the rest of the human body's systems also have various uses?"

"For example, what will the sports system strengthen? Physical strength, physical skills?"

"What about the urinary system? As far as I know, the urinary system can release useless waste toxins from the body, so will it enhance the detoxification ability?"

"It's just that my Heat-Heat Fruit's power can make me immune to all toxins with just high temperatures. High-temperature sterilization is not just talk."

"Reproductive system? Circulatory system? And what about the endocrine system?"

At this moment, Uchiha Huanghuo suddenly had an idea, thinking whether the eight systems of the human body would have similar benefits as the respiratory system and digestive system.

However, if you think about it carefully, even if the secret techniques of the eight systems of the human body are successfully developed, many functions will be repeated or conflicting.

In addition, Uchiha Huanghuo does not have enough knowledge to develop the secret techniques of the eight systems.

"Breath of Fire and Six Treasury Immortal Thief will be enough for me for a long time. I won't consider other human body system secrets for now."

"But I can mention it to Master Orochimaru. I think Master Orochimaru will be interested in the secrets of the eight systems of the human body."

Uchiha Huang Huo thought that if Master Orochimaru successfully developed a secret technique for a certain human system, then he could use it.

At this moment, Huang Huo put his thoughts on the Sealing Technique Six Treasury Immortal Thief again, and once again felt the changes that this secret technique brought to him.

"The original Six Treasury Immortal Thief can seize the vitality of heaven and earth for his own use. He can maintain his life without eating, and also shows strong healing effects."

"My version of the Sealing Technique of the Six Storehouses Immortal Thief does not have these functions, but the digestion power is terrifying."

"Hmm? The Six Treasury Immortal Thief strengthens himself with the power of digestion, and the Fire Breathing strengthens himself with breathing. How is this similar to eating essence and transforming it into qi, or refining essence and transforming it into qi?"

"If you think about it carefully, the limit of the breathing method is probably the immortal body, so is this also considered an alternative way of cultivating immortals?"The eating essence and transforming it into qi and refining essence and transforming it into qi mentioned by Uchiha Huanghuo are of course different from the original version. Is this just the ninja world's version of cultivating immortals?

"Maybe it's really cultivation?"

Huang Huo guessed this in his heart, but he couldn't confirm it, but he still kept some thoughts.

Three days of vacation passed, Orochimaru immersed himself in the laboratory, and asked Uchiha Huang Huo to lead the team to accept the mission.

The eighth team came to the place where the ninja mission was issued in the Hokage Building.

"Just take a D-rank mission and use the rest of the time for training."

However, Hongdou disagreed and retorted on the spot:

"Huang Huo, D-level missions are too boring, let's go and take a look at C-level missions."

It seems that the previous D-level missions left a deep impression on Hongdou.

Uchiha Huang Huo was helpless:"Why don't you want to complete B-level missions?"

Hongdou grinned:"B-level missions? That's good too, but can the three of us, Genin, take B-level missions?"

Uchiha Huang Huo:"You also know that we are Genin, right? Without a Chunin or Jonin leading the team, we can't take missions above C-level!"

Hongdou was not convinced:"But we are Orochimaru's disciples, don't we have any privileges?"

Uchiha Huang Huo:"Privileges? You think too much, stop it, just complete a D-level mission and be done with it."

Hongdou was still a little persistent:"But D-level missions are so boring."

Uchiha Huang Huo said firmly:"Hongdou, I am the captain of Team 8, so it's decided."

Hongdou was struck by lightning:"Damn, the captain is great? Huang Huo, you will regret it!"

The usually cold Hyuga Touko also curled up the corners of her mouth.

At this moment, the Konoha ninjas standing guard in the Hokage Building seemed to feel that the conversation between Huang Huo and Hong Dou was very familiar.

In this way, a D-level mission was completed and the ninjas of Team 8 were disbanded on the spot.

Uchiha Huang Huo went to find Teacher Orochimaru to learn and exchange knowledge.

During this period, he also mentioned to Teacher Orochimaru the speculation about the secret techniques of the eight systems of the human body.

Orochimaru was indeed very interested in this:"So, Huang Huo, your breathing of fire belongs to the secret technique of the respiratory system, and the sealing technique of the Six Treasury Immortal Thief belongs to the secret technique of the digestive system."

"Then the motor system, nervous system, urinary system, reproductive system, circulatory system, endocrine system, these human systems should be able to achieve similar secrets."

But Orochimaru thought about it for a long time and found that as Huang Huo thought, it really requires a more abundant knowledge reserve.

If you want to complete similar secrets, human experiments are inevitable.

At this point, Orochimaru asked Uchiha Huang Huo about his opinion on human experiments.

"Human experiment? This is a must for developing ninjutsu and learning knowledge."

"Even the second generation Hokage Senju Tobirama used a lot of human experiments to develop ninjutsu secrets."

"Before conducting human experiments, it is best to try it on animals first, solve the problem as much as possible, and then conduct human experiments, so as not to waste"

"There are so many bandits and traitors in the ninja world, and there are so many people who have committed heinous crimes. I don't have any psychological burden to use these evil people for human experiments."

Thinking carefully, Uchiha Huanghuo has only conducted experiments on small fish, mice, rabbits and other animals.

It seems that he has not conducted any experiments on the human body.

I almost forgot that Huanghuo has also completed the experiments of fire breathing and six-storehouse immortal thieves on his own body.

It's just that the premise of this experiment is that Huanghuo can be sure that there is no danger to his life.

The power of the Heat-Heat Fruit can make Uchiha Huanghuo safe and worry-free

""Haha, Huang Huo, we are indeed the same kind of people. It seems that we can deepen our communication in the future."

Orochimaru smiled happily, washed his face with his tongue, and gave Uchiha Huang Huo a few scrolls.

Most of Orochimaru's experimental knowledge was recorded. Uchiha Huang Huo collected them as if they were treasures and went back to study them.
