Chapter 18: Chapter 18: Fujinhoin
Time flew by, and in the blink of an eye, anotherthree months had passed.
During these three months in the Sealing Squad, Tatsuya's daily life was relatively monotonous.
Learning sealing jutsu was indeed a difficult undertaking. Even with the bio-chip's assistance, Tatsuya spent a considerable amount of time just recording a vast amount of ninjutsu knowledge.
Tatsuya felt his progress was slow, but Sakamoto An considered him a genius in learning sealing jutsu. According to Sakamoto An, Tatsuya's current sealing jutsu proficiency had already reached the chunin level.
Besides studying and researching sealing jutsu, Tatsuya also spent a significant amount of time each day training in chakra refinement and various basic ninjutsu.
In these three months, Tatsuya felt his strength had improved considerably, and his chakra reserves had steadily reached the level of a Konoha chunin.
At his current level, Tatsuya should be able to pass the chunin exams if he were to participate.
However, Tatsuya wasn't in a hurry. He preferred to develop quietly and steadily. Low key and steady wins the race.
This evening, at 9 PM, the Akimichi clan compound was peaceful and quiet.
Tatsuya entered a secluded training room, carrying a sealing scroll.
It was a 30-40 square meter training room, equipped with an experimental table and some simple tools.
Three months ago, on the very day Tatsuya and his team returned to Konoha, the bio-chip had detected a special seal formula in his body.
This seal formula wasn't something Tatsuya had deliberately created; it was a naturally formed, flowing pattern, like a muscle memory deeply ingrained in the Akimichi clan's genetic code.
If Tatsuya hadn't coincidentally tasked the bio-chip with long-term body monitoring, he might have easily missed it.
Using the bio-chip, Tatsuya had successfully replicated this seal formula.
To test the function of this seal formula, Tatsuya had purchased dozens of ordinary green snakes from the market over the past two months for experimentation.
Through repeated observation and experimentation, Tatsuya finally confirmed that this natural seal formula carried by his clan members could quickly convert food ingested into the body into a special form of body energy.
This body energy was different from the body energy refined by ordinary chakra refinement techniques; it contained another type of energy very similar to body energy.
After analysis and deduction by the bio-chip, this energy was determined to be life energy.
Thus, Tatsuya finally unraveled the mystery of the yang-attribute chakra possessed by the Akimichi clan.
This natural seal formula was the key to the Akimichi clan's ability to rapidly convert food energy into a special body energy mixed with life energy.
However, although this seal formula could quickly convert food energy into special body energy, the efficiency of absorbing and converting this body energy varied greatly among individuals.
This might be determined by inherent differences in constitution.
Moreover, this seal formula couldn't directly refine body energy into chakra; it needed to be used in conjunction with the Akimichi clan's chakra refinement technique.
Through his research on this natural seal formula, Tatsuya had two hypotheses about the origins of the Akimichi clan.
One was that the Akimichi clan, like the Senju and Uzumaki clans, were descendants of the Sage of Six Paths, and their talent was inherited from the Sage's Sage Body.
The other was that the Akimichi clan's ancestors might have carefully studied the Sage Body, extracting this seal formula from it. Then, through generations of continuous development and learning, it was passed down to their descendants like a kekkei genkai, eventually forming the current secret technique ninja clan.
At the same time, a bold idea was born in Tatsuya's mind: to combine the Akimichi clan's chakra refinement technique with this natural seal formula to create a new seal, and then engrave it onto his own body.
In this way, Tatsuya's body would have an automatic chakra-refining cheat, allowing him to quickly increase and recover his chakra reserves as long as he had enough food.
As soon as this idea emerged, the bio-chip in his body immediately provided a solution: sealing jutsu.
This was the main reason why Tatsuya had suddenly requested to join the Sealing Squad to study.
After this period of learning, Tatsuya was no longer a novice in sealing jutsu. Relying on the bio-chip's powerful computational abilities, Tatsuya had already simulated a sealing jutsu in his mind, and now he just needed to conduct real-world experiments.
The bio-chip wasn't omnipotent; although some conclusions could be derived through analysis and deduction, they still required a large number of experiments for verification.
Tatsuya had always been cautious in this regard.
After all, these ninjutsu were to be used on his own body; if something went wrong, it would be difficult to reverse!
For ease of experimentation, Tatsuya had pleaded with Akimichi Rouu to specifically request this training room for him within the clan.
Release!
Entering the room, Tatsuya placed a sealing scroll on the experimental table and unrolled it. He formed hand seals and pressed his hand on the scroll.
Poof!
A cloud of white smoke rose, and a two-meter-long green snake appeared on the table.
Hiss… Hiss…
The snake on the table flicked its tongue, rubbing its head affectionately against Tatsuya's arm, displaying extreme closeness and attachment.
This green snake, just half a month ago, had been an ordinary green snake less than a meter long, the last survivor of the snakes Tatsuya had purchased for experiments.
Under Tatsuya's constant experimentation, this snake hadn't suffered any harm. Instead, its body had more than doubled in size during this time, and it had even developed faint chakra within it, becoming a ninja snake that could be sealed and summoned.
"Good boy! Lie down!"
Tatsuya gently stroked the snake's head, calming the excited snake, and then signaled it to lie down.
The snake obediently lay down, and Tatsuya's expression turned serious. He quickly formed hand seals.
It was an extremely complex set of hand seals. As soon as the seals were completed, Tatsuya pressed his right hand on the snake's body, and an ink-black sealing formula immediately began to move across the snake's body.
Thump…
As the sealing formula formed, a muffled sound, like a heartbeat, came from the snake's body, and then its body began to rhythmically pulse slightly. At the same time, a faint chakra fluctuation also emanated from the snake.
A few seconds later, the snake opened its mouth wide, its tongue extended, and its body began to sway uncontrollably on the experimental table.
Tatsuya watched all this with a serious expression. He took a piece of fresh meat from the side and threw it to the snake, which had its mouth wide open.
The snake's body gently rose, and it snatched the meat in one bite, swallowing it whole in a few gulps, causing its entire body to bulge twice its size.
The snake's body trembled even more violently after swallowing the food, and the freshly eaten meat was being digested at an extremely rapid rate due to the vibrations.
In just fifteen minutes, Tatsuya saw the snake's body return to normal.
Simultaneously, a faint energy slowly emanated from the snake's body and dissipated into the air.
This energy was the special body energy that Tatsuya was very familiar with. When using his family's secret technique to absorb ingested food, Tatsuya's body also produced this kind of body energy.
Half an hour later, the green snake on the experimental table raised its head again, opening its mouth slightly and looking at Tatsuya.
The several-kilogram chunk of fresh meat it had just eaten had been completely digested, and the feeling of hunger returned.
Seeing this, Tatsuya picked up another piece of fresh meat and threw it to the snake, simultaneously beginning to use the experimental data recorded in the bio-chip.
Another half hour passed, and the food in the snake's body was once again completely absorbed.
After this feeding, the snake, having absorbed enough body energy, didn't continue to thrash about and slowly fell into a deep sleep.
Success!
Judging from the snake's reaction, Tatsuya knew his experiment had been successful.
The sealing jutsu he had previously used on the green snake was the result of the bio-chip's deduction and simulation. Tatsuya had named it Fujinhoin.
The Fujinhoin was a cheat that could automatically extract chakra. It could not only quickly convert food energy into the Akimichi clan's unique chakra but also store excess body energy in the body.
Moreover, the Fujinhoin could be stacked with multiple seals.
Through previous experiments, Tatsuya discovered that although the Fujinhoin significantly increased the subject's appetite, it also had an upper limit.
By adjusting the number of Fujinhoin applied based on the subject's constitution, the caster could control the upper limit of food intake.
According to the data comparison before and after the experiment, the Fujinhoin on the green snake had increased its food intake more than tenfold. Meat that would normally take more than ten days to digest was digested by the snake in just over an hour.
Most of this absorbed food energy was converted into special chakra, which had an astonishing effect on the snake's growth rate.
More importantly, although the Fujinhoin accelerated the snake's food absorption rate, it didn't break its original physical limitations; its absorption efficiency and upper limit for food were still limited.
This completely reassured Tatsuya. The effects of the Fujinhoin were indeed controllable and wouldn't randomly create a terrifying, all-consuming monster with a huge appetite.
At this current growth rate, if there was enough food supply, it was not impossible for the green snake to eventually grow into a powerful summoning beast like Manda.
Thinking of this, Tatsuya couldn't help but feel a surge of excitement.
However, all of this was based on Tatsuya having sufficient financial resources. Without money, just one green snake could bankrupt Tatsuya.
Release!
After a brief moment of daydreaming, Tatsuya released the Fujinhoin imprinted on the green snake and then sealed it back into the sealing scroll.
After cleaning everything up, Tatsuya took the sealing scroll and went home to rest.
Although this experiment was very successful, it wasn't yet perfect, and there were still some areas that needed experimental data to fine-tune.
For example, judging from the green snake's current absorption efficiency of life energy, eight Fujinhoin were clearly too many, and a lot of unabsorbed body energy was wasted, dissipating into the air.
However, the first step had been taken, and the next steps should follow naturally.
Over the next few days, Tatsuya spent his time constantly experimenting and collecting data.
