Sasuke turned on Rinnegan and observed the mountain carefully. "There is indeed an abnormal Chakra Wave movement, and it is very strong."
"How many people are there?" Karin also started to sense.
"At least a hundred." Karin frowned, "And a few of them Chakra are particularly powerful, they should be at the Jonin level."
"There are other things." Sasuke's expression became serious, "I felt the chakra fluctuations of the tailed beast."
"Artificial Tailed Beast?" Naruto immediately became alert.
"Probably." Yuki-onna nodded, "I said before, they made at least three Artificial Tailed Beast. It seems that they are all in this base."
Nine-Tails made a dissatisfied voice inside Naruto: "These artificial fakes really make me sick."
"Nine-Tails, can you feel their specific conditions?" Naruto asked in his heart.
"I can only feel the fluctuations of Chakra." Nine-Tails replied, "But I can be sure that their strength is approximately equivalent to one-third of my strength."
"One third?" Naruto was a little worried, "That's pretty strong."
"It's really strong against ordinary ninjas." Nine-Tails admitted, "But it's not strong enough against us."
"Then how do we get in?" Karin asked, "A frontal attack is definitely not possible, there are too many people."
"I know a secret passage." Yuki-onna said, "There is an abandoned mine on the other side of the mountain, which can lead directly to the inside of the base."
"How do you know so clearly?" Sasuke was a little doubtful.
"Because I have worked in this base before." Yuki-onna confessed, "Although the time has not been long, I still have a good understanding of the internal structure."
"Ever worked?" Naruto looked at her doubtfully, "Didn't you say you were a victim?"
"There is no contradiction between the two." Yuki-onna's voice was filled with pain, "Danzo treated me as an experiment and also forced me to work for Root Organization. Later, Shadow Organization took over some of Gen's assets, and I was also transferred here."
"Then how did you escape?" Karin asked.
"An unexpected opportunity." Yuki-onna said simply, "We will talk about the details later. Now let's focus on completing the task."
The four of them went around to the other side of the mountain and found the mine Yuki-onna mentioned. The entrance to the cave was blocked by some weeds and it looked like it had not been used for a long time.
"Are there any traps here?" Sasuke asked warily.
"Probably not." Yuki-onna shook his head, "This passage was discovered accidentally. People at Shadow Organization probably don't know about it."
The four of them entered the mine carefully. It was dark inside and could only be illuminated by a flashlight.
After walking for about ten minutes, a metal wall appeared in front of me.
"This is the outer wall of the base." Yuki-onna pointed to a small door on the wall, "From here you can enter the storage room of the base."
"The door is locked." Naruto tried to push the door.
"I'll do it." Sasuke stepped forward and Rinnegan carefully observed the door lock, "This is the Chakra lock. It requires a specific Chakra to open it."
"I have the key." Yuki-onna took out a small device from his arms, "I stole this when I left."
She attached the device to the door lock and entered a complex Chakra sequence.
"Click." The door lock opened.
The four people entered the base and found that they were indeed in a storage room. There were various supplies and equipment piled around them.
"Where is the research room?" Naruto asked in a low voice.
"Follow me." Yuki-onna led everyone through the storage room and came to a corridor.
The corridor was very quiet, except for the sound of machines running in the distance. The lights on the walls were dim, creating a depressing atmosphere.
"Why is the defense here so loose?" Karin said in confusion, "We didn't encounter any guards along the way."
"Because they think it is very safe here." Yuki-onna explained, "The base is built deep underground and is in a hidden location that ordinary people cannot find."
"That's their mistake." Sasuke sneered.
The four of them continued to move forward and soon came to a fork in the road.
"The left leads to the research room, and the right leads to the area where Artificial Tailed Beast is imprisoned." Yuki-onna introduced, "Where should we go first?"
"Go to the research laboratory first." Naruto decided, "Destroy their research data and prevent them from creating more Artificial Tailed Beast."
The four of them walked to the left, and the corridor became more spacious, with some strange charts and formulas hanging on the walls.
"What are these?" Karin looked at those charts curiously.
"The manufacturing principle of Artificial Tailed Beast." Yuki-onna replied, "They decomposed the power of Tailed Beast into data, and then reassembled it using scientific and technological means."
"Sounds very complicated." Naruto scratched his head.
"It's really complicated." Sasuke was also observing those formulas, "But the principle is not difficult to understand. They are actually simulating the Chakra characteristics of Tailed Beast."
At this moment, footsteps came from ahead.
The four of them immediately hid in the shadows by the wall.
Soon, two researchers wearing white lab coats walked by. They were discussing something as they walked.
"The data of Experiment No. 3 is still unstable." one of them said.
"It doesn't matter, Lord Shadow said, as long as it lasts for an hour, it's enough." Another answer.
"An hour? Isn't that a disposable item?"
"The manufacturing cost is not high anyway, just throw it away after use."
The conversation between the two made Naruto and others feel angry. These guys completely regard life as a tool.
After the researcher walked away, the four of them continued moving forward.
Soon, they arrived at the door of the research room. Through the glass window, they could see a dozen researchers busy inside.
"How to get in?" Naruto asked, "Can you just rush in?"
"No." Yuki-onna shook his head, "There is an alarm system inside. Once triggered, everyone in the entire base will know."
"What should we do?" Karin asked.
"I have a way." Sasuke said, "Use illusions to make them Gate of Opening."
He turned on Sharingan and cast an illusion spell on a researcher inside.
The researcher suddenly stood up, moved the machine Earth Flow to the door, and entered the password Gate of Opening.
"Successful!" Naruto said excitedly.
The four of them took the opportunity to rush into the research room. Before the researchers inside could realize what was happening, they were controlled by Sasuke's illusion.
"No one is allowed to move!" Naruto said loudly.
The researchers were trembling with fear and did not dare to resist.
"Yuki-onna, you go find important research information." Sasuke commanded, "Karin, you monitor these researchers. Naruto, you and I destroy the equipment together."
The four people worked together and began to destroy the laboratory.
Yuki-onna quickly found a host. "All the research materials are here!"
"Then completely destroy it!" Naruto raised his fist and was about to hit the host.
