Uchiha's personal opinion

White Zetsu swayed and fell to the ground.

Uchiha Tokumitsu examined the wound on his head and found that his skull was empty.

He then chopped off one of White Zetsu's fingers with a kunai.

After being freed from the sealing rope, the flesh-colored fingers turned as pale as withered branches.

Uchiha Tokumitsu took out another sealing scroll and used a hand seal to seal the White Zetsu's corpse.

"Looks like he's really dead..."

Living things cannot be sealed inside scrolls.

After placing the severed White Zetsu finger into another sealing scroll, Uchiha Tokumitsu casually condensed a ball of Fire Release chakra and tossed it to the ground.

"boom!"

The highly concentrated chakra burned out a large hole, and the edges even turned into a glassy appearance.

After carefully disguising the scene as a murder to cover up the crime, Uchiha Tokumitsu walked out of the office.

"Lord Tokumitsu!"

Hyuga Shuhiro immediately came to greet him.

"Let's go check out the prison!"

"Yes, sir! Please follow me..."

Hinata Shuhiro quickly provided guidance.

"...Shuhong-kun, I've heard that the Hyuga clan and the Kaguya clan have a pretty good relationship. Is that true?"

On the way to the temporary prison, Uchiha Tokumitsu casually asked.

"It is said that the two clans were allies during the Warring States period, and the Kaguya clan was not as crazy and violent as it is now..." Hyuga Shuhiro replied, "However, I don't know much about the specific history, because this is knowledge that only the main family can possess."

"Is that so~"

Uchiha Tokumitsu, I wonder if that's alright?

"Are prisoners always confined to prison?"

"Yes, we never let them leave!"

"That's good……"

Uchiha Tokumitsu nodded slightly in approval.

"...This is it."

Hyuga Shuhiro led Uchiha Tokumitsu to the entrance of a tunnel.

The deep, dark staircase led into the darkness, like a monster ready to devour its prey.

"I'll go down and take a look. You wait here for a while."

"As ordered!"

Hinata Shuhiro responded respectfully, then turned around.

Uchiha Tokumitsu slowly walked into the depths of the prison.

The small underground space was divided into several cells, but none of them were occupied. The walls gleamed with a steel-like luster, clearly reinforced by sealing techniques.

Uchiha Tokumitsu stretched out his hands and pressed them down, and the flames of his Fire Release spread out like flowing water, quickly filling the cell.

"Squeaky!!!"

Suddenly, two strange screeching sounds, like rats with their tails burned, came from the walls and ceiling. Two white, swollen masses emerged and pounced towards Uchiha Tokumitsu.

"Whoa!"

Uchiha Tokumitsu casually threw out two kunai, piercing the white, swollen mass through it.

Thump~

The remains fell to the ground, stirring up a cloud of dust.

"Spore Technique..."

Uchiha Tokumitsu snorted coldly, feeling relieved. He then took out a sealing scroll and sealed the two underdeveloped White Zetsu.

I wonder how long White Zetsu can stay fresh after death.

Chapter 160 The Difficulty of Cell Extraction

After emerging from the dungeon, Uchiha Tokumitsu nonchalantly arranged various military affairs, keeping Hyuga Shuhiro and the garrisoned ninja in a state of chaos, and took the opportunity to survey the entire camp area.

After confirming that nothing had been missed, Uchiha Tokumitsu ordered his men to bring out the two Kaguya ninjas who had been tortured and were covered in wounds. Without caring whether they had gotten any information from the interrogation, he bound them tightly with chakra sealing ropes and gagged them, then ordered his accompanying guards to carry them back to the eastern camp.

Upon returning to his base, Uchiha Tokumitsu's first action was to send the two Kaguya ninjas to the laboratory and select three Jonin and six Chunin from his Uchiha ninjas to form a special guard dedicated to protecting the laboratory's security.

The discovery of White Zetsu in the old camp of the Land of Whirlpools put Uchiha Tokumitsu on edge.

Fortunately, based on vague memories from his previous life and the events surrounding the capture of the White Zetsu's twins, the high-strength sealing barrier was still able to prevent the White Zetsu from invading.

After handing over two Kaguya ninjas to the Uzumaki researchers and incorporating them into the laboratory (their duty was to be studied), their first special research task was to extract genetic material from the Kaguya ninjas' bones.

Uchiha Tokumitsu's true purpose was not to covet Kaguya's bloodline limit, Shikotsumyaku, but to obtain an effective method for extracting genetic material based on the research of the Uzumaki researcher.

What he wanted was the extraction of leukemia cells.

However, the white Zetsu cells were too unusual for him to handle, and he had no intention of handing them over to the researchers at the Vortex Research Institute.

If the Uzumaki researchers mistake it for something like Hashirama cells and cause unnecessary commotion, it could damage the relationship between the Uchiha and Uzumaki clans.

Furthermore, Uchiha Tokumitsu did not want to transplant White Zetsu cells so crudely.

Who knows if the White Zetsu he captured was an ancient relic or something Madara Uchiha created by modifying his best friend's flesh? It would be too embarrassing if a human face grew out of its chest or some other part of its body.

The experiment was not something that could be accomplished overnight. Uchiha Tokumitsu was not in a hurry to leave. Instead, he returned to his office in the laboratory and found some books to read.

While reading, he also verified his limited biological knowledge from his previous life.

Anyway, this world has magical chakra, so maybe the power of "I think" can also be put to use.

Based on my past life's impressions, there are two main methods for extracting genetic material from cells: chemical and physical methods.

Chemical methods mainly involve inhibiting and separating the cell wall through proteases or solvents. This method can extract a large amount of cytoplasmic DNA, but the extraction efficiency is low and it is relatively easy to be contaminated.

Furthermore, Uchiha Tokumitsu did not know which substances in the White Zetsu cells were the truly useful source of the Divine Tree or the power of Wood Release, and a large number of experiments were still needed to verify this.

Physical cell extraction methods primarily involve using external forces, such as centrifugation or ultrasound, to disrupt the cell structure and separate the cell DNA.

While physical extraction methods can also separate genetic material, they also carry the risk of contamination, and require essential pre-treatment equipment.

Uchiha Tokumitsu took out his notebook and neatly wrote three words on it: centrifuge.

Although centrifuges were often portrayed as weapons of mass destruction in the news of my past life, they are actually used in many industrial fields as an industrial piece of equipment.

This includes industries such as coal ore dressing, oil refining, and food processing.

Even the most common cream whipper works on a similar principle to a centrifuge.

Given the technology of the ninja world and the financial resources of the Uchiha clan, building a usable centrifuge should not be difficult; the key lies in how to effectively separate genetic material.

The root of all this depends on whether the researchers, Uzumaki and Kaguya, who are busy in the main laboratory, can provide adequate support.

Only by mastering a feasible experimental method can we lay the foundation for maximizing the effect of white monsters.

……

After taking a nap in his office, Uchiha Tokumitsu pondered a bunch of experimental methods that he didn't know if they were useful or not, and after processing a large stack of official documents sent by his subordinates, the laboratory door slowly opened.

Researchers with eyes as red as rabbits filed out.

Kaguya, bound like a rice dumpling, was also pushed out by the researchers.

"Has the experiment yielded any results?"

Uchiha Tokumitsu asked the Uzumaki researcher who was carrying a small bottle.

"A major breakthrough has been achieved in the extraction of genetic material from the mortal veins..."

"The vortex researcher answered in a low voice."

Upon hearing the words "major breakthrough," Uchiha Tokumitsu's brows immediately furrowed.

"You'd better believe there really is a breakthrough..."

Uchiha Tokumitsu muttered resentfully.

"...The experiment has indeed achieved a breakthrough."

The researcher gave an awkward smile, also feeling a little embarrassed, and deliberately omitted the word 'significant,' saying, "We did indeed extract bloodline substances from the Corpse Bone Vein power..."

As he spoke, the researcher handed over the bottle in his hand.

Uchiha Tokumitsu took the bottle and saw that inside the semi-transparent bottle, a semi-liquid substance resembling a gray nebula was imprisoned.

"This is……"

Uchiha Tokumitsu raised an eyebrow.

"This is based on the Kaguya clan's Shikotsumyaku power extracted from the researchers' chakra and bone marrow. However, it contains too many impurities and a large amount of negative energy that can cause emotional instability and abnormal bone growth. It also exhibits extremely strong rejection of foreign bodies, so transplantation is not currently possible..."

The Uzumaki researcher assumed that Uchiha Tokumitsu's purpose in extracting the power of the Corpse Bone Pulse was to steal the bloodline limit, so he offered a warning.

This is also why the power of the Bloodline Ninja Clan is rarely revealed.

Obtaining these bloodline powers is not difficult; the difficulty lies in eliminating the rejection reaction after transplantation.

The same applies to the Sharingan of the Uchiha clan. One can obtain the power of the Sharingan by killing an Uchiha clan member who has awakened it and gouging out their eye. However, those who attempt to steal the Sharingan through transplantation are often drained of their chakra and die.

Among the various ninja clans, the Hyuga clan's Byakugan has the least adverse reactions after bloodline transplantation. Therefore, most of their clan members are imprisoned by the Caged Bird Seal.

Of course, it cannot be ruled out that there were some bloodline limits in the ninja world that were easy to transplant and plunder, but they should have been wiped out by endless greedy covetousness.

"...That's normal."

Although Uchiha Tokumitsu felt somewhat disappointed, he also believed that this was understandable.

If the power of bloodline limits were so easily stolen, bloodline ninjas would have been rampant in the ninja world long ago.

Is it possible to eliminate the adverse effects?
