Warlock Invasion of Naruto.

The two walked for about half an hour and arrived at a small hill, reaching its foot. Orochimaru swiftly formed hand seals, then slammed his hands on the ground. The grass in front of him trembled, and then the ground sank, revealing a hole with a diameter of more than three meters.

Bai Yu peered into the deep cave and saw steps leading down into the dark underground.

As Orochimaru walked, he explained, "This is the laboratory I set up outside the village. You can use the equipment and facilities here."

"Yes, Orochimaru-sensei," Bai Yu replied. Being outside the village made many things much easier.

"The roots will send over experimental materials regularly. Remember to receive them when I'm away."

Orochimaru said calmly.

"I wonder what the experimental materials are..." Bai Yu's heart stirred.

"You can use spies from enemy countries and death row inmates without worry. The village doesn't do these things openly, so be careful when you come and go so that no one else notices you."

Orochimaru reminded him that he had high hopes for Shiraha's talent and was therefore quite attentive to him.

"Yes."

Bai Yu followed Orochimaru to the end of the steps. Before them lay a deep, dark corridor that seemed to stretch on forever, with lamps hanging on the walls on either side, emitting a faint glow.

In his perception, the entire stronghold was covered by a medium-sized barrier, which suppressed his perception to some extent.

It seems that Orochimaru also has some knowledge of sealing techniques.

At the end of the corridor was a room. Bai Yu went in and saw that the space inside was not very large, but it was fully equipped with all kinds of experimental equipment, including a large culture chamber.

Besides various equipment, the experimental table was filled with bottles and jars containing animal specimens, mostly snakes, as well as some strangely shaped creatures.

Orochimaru approached the lab table and took out a storage scroll from his robes: "These are first-generation cells from the third generation, but their activity is very low. You can use them for practice, but be careful."

"Yes." Bai Yu took the scroll, suppressing his excitement. After so much preparation, he finally got his hands on the first generation cells.

"Wait here for me, I'm going to Root." Orochimaru said, then tossed a scroll to Bai Yu: "This is the technique for entering and exiting the barrier."

After saying that, Orochimaru left, leaving Shiraha in the laboratory.

Once Orochimaru left, Shiraha quickly retrieved the First Hokage's cells from the scroll.

Inside a fist-sized bottle was a large, clear green liquid, about half full. At the bottom of the bottle was a piece of flesh about the size of a thumb.

"Eye of Truth", "Sixth Sense", and "Five Senses Enhancement" are activated.

The small bottle radiates a powerful energy field.

Bai Yu went to the microscope, used a dropper to draw up some green liquid, and placed it on a glass slide. The cells inside were incredibly active.

"This is what you call low cell viability?!"

Bai Yu picked up the dropper again, diluted a drop of solution containing the first generation of cells thoroughly, and then touched it with her finger.

A slight tingling sensation came from my fingertips.

At the same time, "The Eye of Truth" is rapidly becoming data-driven.

[Cells obtained from a super-radiated organism (1/1), cell viability and blood purity are low, but meet standards; Quality: Ordinary]

Bai Yu brought his fingers close to his eyes and saw that the skin on his fingertips was slightly greenish and felt hard to the touch, with a rough texture like tree bark.

He used a scalpel to cut off a small piece of hardened skin and placed it under a microscope.

The scene before him made Bai Yu's pupils shrink. The skin he had cut off had become woody, almost identical to the woody cells inside a tree trunk.

"No wonder none of the participants in the Wood Release experiment survived; it's truly terrifying!"

Was the First Hokage human? Did he possess the bloodline of a tree?

This is somewhat similar to the bloodline sorcerers described in the ancient texts.

The First Hokage was a sorcerer who inherited the bloodline of some kind of plant-based supernatural being, but his power was not inherited through bloodline or chakra.

The Wood Release experiment is like artificially cultivating ninjas with "Wood Release bloodline".

"This is only of average quality. If the activity level were high enough, it might reach excellent or even perfect quality."

Bai Yu thought to himself.

After receiving the Nine-Tails cells, his chakra level did not increase significantly, but he felt his energy had increased considerably.

"It seems we need to find a way to obtain more viable primary cells..."

[Chapter 62. Technological Breakthroughs and Improved Drugs]

October of Konoha 38.

A year has passed since the Second Shinobi World War ended completely.

All the ninja villages entered a period of relative peace and began to recover.

There is a small mountain about several dozen miles from the east gate of Konoha.

At the foot of the mountain, in an underground laboratory.

Shiraha and Orochimaru, dressed in green surgical gowns and wearing white gloves, stood on either side of the operating table.

On the operating table lay a young man with his upper body exposed. Surprisingly, the young man's right arm was deathly pale, and the skin color showed a clear difference starting from his shoulder.

The two men kept a close eye on the young man, paying attention to his physical condition and the changes in the data on the instruments.

When the scheduled time passed, the two of them breathed a sigh of relief.

Orochimaru used a scalpel to cut off a small piece of flesh from the young man's arm and handed it to Shiraha.

Bai Yu placed it under a microscope for careful observation.

"How is it?!" Orochimaru didn't step forward to observe, but his eyes held a hint of tension as he looked at Bai Yu, clearly taking the result very seriously.

"The cells have basically fused together, there is no rejection reaction, it's a success!"

There was a hint of excitement in Bai Yu's eyes.

Orochimaru was also somewhat excited, but then calmed down and frowned slightly, saying, "The success rate is still too low."

“Indeed.” Bai Yu regained his composure and analyzed, “Including the previous failed experiments, the cell fusion success rate is less than 5%. However, as long as we succeed once, by continuously eliminating variables, we will definitely improve the success rate.”

"Yes." Orochimaru nodded in agreement, a smile appearing on his face. "Thanks to you this time!"

"It's mainly thanks to Orochimaru-sensei. If this continues, we'll be able to develop a perfect limb regeneration technique sooner or later."

Bai Yu said with a smile.

Orochimaru glanced at the young man lying on the operating table and said indifferently, "Go and rest first."

The young man stepped down from the experimental table and bowed respectfully to Orochimaru and Shiraha: "Yes, Lord Orochimaru, Lord Shiraha."

After saying that, he left the laboratory and returned to the cell next door.

"Bai Yu, I'm giving you two days off. You should get some rest." Orochimaru looked tired, but his eyes held an uncontrollable excitement.

"Yes." Bai Yu took off his surgical gown and gloves and left the laboratory.

He didn't try to persuade Orochimaru to rest, because it was pointless.

As Bai Yu walked out of the laboratory and passed the cells in the corridor, he glanced at the few remaining experimental subjects inside and frowned slightly. He had been expending a lot of energy lately.

However, everyone inside remained quiet, and there was no disturbance.

These were all death row inmates provided by Root to Orochimaru for human experimentation.

Orochimaru promised that if you cooperated with him for two rounds of experiments and survived, you would gain your freedom.

It must be said that Orochimaru does possess a magical charm.

Sometimes, Orochimaru would bring people in from the outside. Everyone who came here knew that they would be used as test subjects, but they all showed great excitement and were more cooperative than death row inmates.

The young man had successfully survived two rounds of experiments, but he insisted on staying in the lab and didn't want to leave at all.

The limb regeneration technology has now completed its first phase. Although there may be a second, third, or even fourth and fifth phase, this success is crucial.

Among them, the most important is the white humanoid biological cells provided by Bai Yu.

Bai Yu obtained the first-generation cells last year and made a major discovery after research.

The white creature he captured from the Land of Grass had cells that were remarkably similar to those of the original generation.

Furthermore, when the less active primary cells were transplanted into the white organism, the two cell types successfully fused together.

Apart from a decrease in cell activity, there was no phagocytosis.

However, Bai Yu's experimental progress then came to a standstill.

He then brought the body tissue of the white-like creature to Orochimaru, and the two conducted research together.

During this time, Orochimaru also made a special trip to the Land of Grass, seemingly hoping to see if he could capture the white creature again.

Of course, the final result was that they returned empty-handed.

However, this amount of body tissue is sufficient.

After nearly a year of repeated experiments, the two finally succeeded in cultivating and transplanting cells of white organisms.

The cells of the experimental subject and the cells of a white organism were fused together and then transplanted back onto the experimental subject.

The young man we just saw was the only test subject who survived the experiment, and the arm he grew is now usable.

Despite a success rate of less than 5%, everything is difficult at the beginning, and the success of the first step is crucial.

In addition, Bai Yu made another major breakthrough.

In an experiment six months ago, he accidentally knocked over a petri dish, and the white biological tissue inside fell to the ground. After it came into contact with the ground, a small tree, taller than a person, grew out of it, emitting a special energy field.

Bai Yu cut off a section of the sapling's branches for research, but didn't find anything particularly special.

However, he suddenly had a brilliant idea: to use the powder ground from the tree trunk to make "Deep Blue Potion," and to his surprise, it actually worked.

However, the new version of "Deep Blue Potion" is quite different from the original description of the potion.

Bai Yu used the test subjects provided by Orochimaru to conduct drug experiments. After repeatedly confirming that it was safe, he took a small dose of "Deep Blue Potion" and found that the effect was excellent.

Since the "Active Agent" completely lost its effectiveness, Bai Yu's cultivation speed has slowed down considerably.

Unexpectedly, a chance encounter led him to successfully develop a new type of "Deep Blue Potion".

Many major scientific discoveries and inventions sometimes occur during play or by accident.
