Capital of Fire's night is brightly lit.
In the room on the third floor of "Food Is Heaven", Senju Chen was sitting by the window, looking at the bustling crowd downstairs.
Rin Nohara was lying on the bed, her face pale and her breathing steady. The Three-Tails rampage just now had almost exhausted all her energy.
"Chen-kun..." Lin's voice was very soft, with a hint of exhaustion, "I'm sorry..."
"What are you talking about?" Senju Chen turned his head and smiled, "You have a good rest. From today on, you can chat with Three-Tails when you have nothing to do. When one day it completely accepts you, your crisis will be relieved."
Lin bit her lip, knowing that if it wasn't for Senju Chen, she might have been completely swallowed by Three-Tails.
"Thank you..."
"Okay, okay." Senju Chen waved his hand, "You go to bed first, I'll go talk to Kakuzu about something."
He stood up, opened the door and left the room.
In the office on the second floor.
Kakuzu was sitting at the table, with a pile of account books and reports in front of him. His brows were furrowed, and the pen in his hand was drawing rapidly on the paper.
"Tsk... this month's expenses have exceeded again..." Kakuzu muttered in a low voice, "These cooks are all money-hungry..."
"Dong dong dong--"
There was a knock on the door.
"Come in." Kakuzu said without raising his head.
Senju Chen pushed open the door and walked in. Looking at Kakuzu's serious look, the corner of his mouth couldn't help but twitch.
This old guy... really got into the act.
Kakuzu raised his head and put down the pen in his hand, "Is something wrong?"
"Yeah." Senju Chen walked to the table, pulled up a chair and sat down, "In a while, Xuanyuan Group's Azi will be transformed. You go to Land of Birds with him."
Kakuzu was stunned for a moment.
"Land of Birds?"
"Yes." Senju Chen nodded, "The branch over there has just opened and needs someone to take charge. You go and help stabilize the situation, and then come back when things are back on track."
"There are still several branches in major countries that will be opened in the future, and you will also need to send a few other people there one after another. When these branches are officially on track, you will have nothing to do except go there every year to check the accounts."
Kakuzu was silent for a moment.
"How long will it take?"
"If it's fast, one month. If it's slow..." Senju Chen thought for a moment, "Two months, maybe. After all, you'll get your share of it, so I can rest assured if I leave it to you."
Kakuzu's mouth twitched.
This kid is really good at calling people, but for the sake of money...
"Okay." Kakuzu nodded, "I understand."
"Yeah." Senju Chen stood up and patted Kakuzu on the shoulder, "Thank you for your hard work, old man."
Kakuzu's face darkened.
Old thing... can't this kid have another name?
Senju Chen smiled, turned and left the office.
The next morning.
Senju Chen did not alert anyone and just left Capital of Fire quietly.
Three days later.
Konoha, Senju mansion.
Senju Chen is sitting in his room with a pile of scrolls and information in front of him.
Now that everything outside has been arranged, it's time to take care of your own affairs.
Since the system drew "Earth Grudge Fear", Senju Chen has not been actively studied.
The scrolls in front of them are research reports on "Earth Grudge Fear" in Kakuzu's body compiled by Orochimaru and Amado.
Densely packed texts and diagrams record every detail of Earth Grudge Fear.
"Tsk... it's really complicated." Senju Chen opened the first scroll and frowned slightly.
Earth Grudge Fear is the secret technique of Kakuzu.
It allows the user to capture the hearts of others through black tentacles and transplant them into their own bodies.
Each heart can independently store Chakra and release Ninjutsu with corresponding attributes.
Theoretically, as long as there are enough hearts, the user can have near-immortal vitality.
"But..." Senju Chen put down the scroll and picked up another piece of information, "The flaws of this thing are also obvious."
First of all, the quality of the heart directly determines the user's strength.
If the owner of the heart is too weak, the transplant will be useless.
Secondly, there is an upper limit to the number of hearts.
Kakuzu can only accommodate up to five hearts at the same time. If there are any more, the body will not be able to bear it.
Finally, the transformation of the body by Earth Grudge Fear is irreversible.
Once used, the body will be completely transformed by the black tentacles and can never be restored to its original state.
"Tsk... these flaws should be improved by teachers and others." Senju Chen's eyes flashed with excitement.
He picked up the pen and began to write and draw on the paper.
First, there is the issue of heart quality.
This is easy to solve.
As long as you choose a strong enough ninja as "material", you can ensure the quality of the heart.
Secondly, there is an upper limit on the number of hearts.
Orochimaru Their idea is to use Tailed Beast and Wood Release Cells to strengthen the body, which should be able to break through this limitation.
The vitality and regeneration abilities of Tailed Beast and Wood Release Cells far exceed those of ordinary people.
If the two can be integrated into the transformation process of Earth Grudge Fear, the body's endurance will definitely be greatly improved.
By then, let alone five hearts, even ten or twenty hearts are not impossible.
Finally, there is the irreversibility of body modification.
This...Senju Chen was silent for a moment.
Earth Grudge Fear is originally an extreme secret technique. If you want to gain power, you must pay a price.
If you don't even have this awareness, then you might as well not use it.
"But..." Senju Chen's eyes suddenly became sharp, "I can add something to the original one."
He picked up the pen and quickly wrote a few lines on the paper.
"First, use Wood Release Clone and add Earth Grudge Fear, so that the clone can fight for a longer period of time, or even exist permanently."
"Second, by adding Wood Release, the structure of the black tentacles is improved so that it can absorb and transform Chakra."
"Third, during the process of transplanting the clone's heart, Sealing Jutsu from the Uzumaki Clan is added to ensure that the heart will not overclock and lose control."
"Fourth, as for adding Tailed Beast cells..."
He put down his pen and picked up another document on the table.
That's Orochimaru's research report on Tailed Beast cells.
The characteristics, fusion methods, and possible side effects of Tailed Beast cells are recorded in detail above.
"Side effects..." Senju Chen turned to the last page and frowned slightly.
Tailed Beast cells are extremely erosive.
If the fusion fails, the user's body will be completely devoured by Tailed Beast cells and turned into a pile of rotten flesh.
Even if the fusion is successful, the user will be affected by Tailed Beast's consciousness and become violent and bloodthirsty.
"Tsk... that's a problem." Senju Chen thought for a moment.
But...
"I don't use it on myself. If I just inject it into Wood Release Clone, there should be no problem." A smile suddenly appeared on his lips.
And Wood Release is Kekkei Genkai exclusive to First Hokage Hashirama Senju.
Not only does it have powerful attack and defense power, it can also suppress Chakra of Tailed Beast.
If Wood Release Chakra can be added as a "buffer layer" during the transformation of Earth Grudge Fear...
Senju Chen's eyes are getting brighter and brighter.
"In this way, the corrosiveness of Tailed Beast cells and the influence of Tailed Beast consciousness can be solved at the same time."
He picked up the pen and quickly wrote a few lines on the paper.
"Improved Earth Grudge Fear--"
"The first step is to use Wood Release Clone as the carrier."
"The second step is to improve the structure of the black tentacles and integrate Wood Release into Earth Grudge Fear so that it can absorb and transform Chakra."
"The third step is to fuse Tailed Beast cells to increase Wood Release Clone's vitality and Chakra capacity."
"The fourth step is to use Wood Release Chakra to suppress Tailed Beast consciousness."
"The fourth step is to transplant a high-quality heart to ensure the diversity of Chakra attributes."
"Step six, add Sealing Jutsu to ensure that the heart will not be overloaded and lose control."
Senju Chen put down the pen, looked at the contents on the paper, and raised a satisfied smile at the corner of his mouth.
"Perfect."
"The next step... is practice."
