When the talent Kurama Yakumo was extracted, the "skill slot" of the system had already been filled by Senju Chen.
The seven "skill slots" in the previous system were:
[1: First Wood Release Bloodline]
[2: Uzumaki Clan Bloodline]
[3: Uchiha Clan Bloodline]
[4: Transformation Technique(Top)]
[5: Top-Level Reaction Nerves(Top)]
[6: Summoning Jutsu·Demonic Statue of the Outer Path]
[7: Earth Grudge Fear]
However, Senju Chen has already made preparations to use the talent of Kurama Yakumo to replace the fourth [Transformation Technique (top)].
In the past, [Transformation Technique (Top)] was a magical skill that allowed him to seamlessly switch between various identities and hide from the enemy.
Even when he was Third Shinobi World War, Senju Chen used this skill to disguise himself as Seven Ninja Swordsmen of the Mist of Kirigakure, indirectly cheating Genji of Kirigakure.
But since the emergence of "Perfect Clone" like White Zetsu Clone, which can perfectly copy any person's form, breath, and even the fluctuations of Chakra, the skill [Transformation Technique] seems a bit useless.
Now this skill is dispensable for Senju Chen.
Now that there is a better choice, Senju Chen decisively abandoned this [Transformation Technique (top)] and replaced it with [Soul Mutation] just taken from Kurama Yakumo.
Moreover, Senju Chen discovered that [Soul Mutation], this talent, can break the shackles of one's own mental power. This is not the most powerful thing about it. What is even more perverted is that this talent will continue to increase the upper limit of Senju Chen's mental power as he grows older.
You must know that in the original work, Kurama Yakumo can even erase human bodies in the real world with just a canvas, and even cause lightning to fall out of thin air.
Maybe in the near future, Senju Chen can be a creature of the void like Kurama Yakumo, and even "become a god with your thoughts."
Just when Senju Chen was playing with "throwing knives" in the air and enjoying his "bright future" silly.
A thought was transmitted from the clone far away in the Land of Waterfalls experimental base.
"The first batch of "further training" has been completed."
"Then, it's time to prepare the stage for the arrival of Amado."
Senju Chen stood up, dusted himself off, and prepared to go to the Hokage building.
But this time Amado brought not only "medical technology", but also a large number of "Scientific Ninja Tool" developed by their experimental base over the years.
If some of these "Scientific Ninja Tool" are put to good use, they will be a revolutionary force that can subvert the entire Shinobi World.
If these are exposed in front of everyone's eyes, it will only cause endless prying eyes and trouble for the entire Shinobi World.
It even directly made the current Konoha the target of public criticism. In Konoha, the spies from the major ninja villages are not vegetarians.
Therefore, Senju Chen plans to implement two places, one light and one dark.
On the surface, Medical Department, which is located within Konoha, claims to the outside world that "this is the latest technology of Konoha", and is responsible for reception, reconnection of severed limbs and rehabilitation training after treatment.
This place will become a window and a bait to display Konoha's "advanced" medical technology to the outside world and attract the attention of all Shinobi World.
The production base that integrates biomodification, Scientific Ninja Tool R&D and manufacturing must be placed in an absolutely safe and private place.
--Konoha, the underground base that once belonged to Orochimaru and was later taken over and transformed by him.
There is the real "science factory".
After that, Senju Chen felt like returning to his own home, walking through the Hokage building and arriving at Hokage's Office.
"Sister, I have something to tell you." Senju Chen took Tsunade's hand, led her to sit on the coffee table aside, and poured her a cup of hot tea obediently.
"Oh? What's the matter?"
Tsunade picked up the tea cup and took a sip, enjoying his brother's rare attentiveness.
"It's about the medical hospital. The people I sent out have brought back the scientific researchers and the first batch of equipment, and they are expected to arrive at Konoha in a few days."
"Is it finally coming?" A hint of surprise flashed in Tsunade's eyes.
For amputated limb regeneration, a technology that can change the landscape of Shinobi World, she understands its importance better than anyone else.
"Yes." Senju Chen nodded, and then changed the topic, "But, sister, I've thought about it. This technology... is too shocking. If we set up the core Research and Development Department gate directly in the village, I'm afraid it will cause unnecessary trouble."
"Then what do you mean..." Tsunade frowned upon hearing this.
"My idea is that the Medical Department in the village is mainly used for medical treatment and postoperative recovery." Senju Chen said unhurriedly, "And I plan to set up the production of medical supplies and Scientific Ninja Tool outside the village."
"This can not only ensure the stability of everyone's treatment, but also prevent unnecessary exploration by some people. After all, these technologies are still a bit too advanced."
Tsunade listened and raised his eyebrows slightly.
It turns out that you yourself also know that the things you and Orochimaru are studying are too advanced for the entire Shinobi World?
It is conceivable that once the technology of "Limb Regeneration" is really launched in Shinobi World, then the attention of all Shinobi World will be focused on Konoha.
By then, there will definitely be an endless stream of people coming to seek medical treatment, and at the same time, there will also be an endless stream of overt and covert spies in various ninja villages.
This younger brother of mine is planning to push the entire Konoha to the front desk to block his "secrets"...
However, Tsunade did not find fault with her younger brother, because she knew that everything Senju Chen did was for a reason.
For example, if some medical treatment and experiments need to be completed by Orochimaru himself, Orochimaru, the "Konoha S-level traitorous ninja", cannot be allowed to enter the village openly and treat everyone!
Even if everyone in the village tacitly doesn't mention anything, it will be seen by those from other villages who come for "medical treatment" later...
Damn it, are you Konoha so open-minded???
An S-class renegade ninja actually works part-time as the village's chief physician???
At this time, people will say that Konoha treats "rebellious people" like a joke. If they say they rebel against the village, they will rebel against the village. But after the rebellion is over, they can occasionally "go back to their parents' house to celebrate the New Year". Then Konoha will no longer be a joke to the whole Shinobi World.
Therefore, Senju Chen's current proposal is actually in line with Konoha's "political correctness".
Tsunade nodded after thinking for a moment, "Where are you going to set up the real Medical Department?"
"The teacher has previously established an underground base outside Konoha. The location is extremely secret and the defenses are very complete. I plan to transform it and use it as our real research and development and medical center."
So Tsunade also had an expression that I understand, "Okay, I agree to this plan! If you need personnel, materials, whatever you need, just tell me directly!"
She now has 100% trust in her younger brother's abilities.
Moreover, with his younger brother here, they have quite a bond and bridge between Konoha and Orochimaru. Didn't you see that so many advanced technologies were "abducted" back from Orochimaru by this smart younger brother!
"Hey, sister, don't worry, I won't be polite when the time comes." Seeing Tsunade agreeing so happily, Senju Chen was also slightly surprised, but immediately put on a smile.
