Yuuhi Kurenai closed her eyes, and the surroundings turned pitch black. Although the feeling of chakra loss was still strong, she finally calmed down and began to refine chakra bit by bit.
Various instruments around him made buzzing sounds, and Orochimaru kept moving between the instruments. Occasionally, when it stopped, the sound of the pen tip scratching across the paper could be heard.
Time passed very slowly, at least in her mind.
But in fact, not long after that, the sound of the machine gradually weakened, and Orochimaru stood in front of her again.
"For everything that follows, don't make any movements or resist. Do you understand?"
At this time, even Yuuhi Kurenai's neck had been fixed by Orochimaru, and it was impossible to nod and shake her head. She opened her mouth, with a hint of hoarseness in her voice. "I know."
Orochimaru smiled and nodded, turning on the instrument closest to the operating table. Even with her eyes closed, Yuuhi Kurenai felt a strong light hitting her face, and her eyes received the light dyed red by blood vessels.
Then she felt chakra, which was the chakra of Orochimaru. The chakra entered from her eyes and headed towards her brain.
She really wanted to resist. This level of chakra invasion was far beyond treatment or general experiments. As long as Orochimaru allowed these chakras to deviate even a little bit, her brain would most likely be destroyed immediately.
But she remembered what Orochimaru had just said, and she endured it forcefully.
Suddenly, she couldn't tell whether it was her scalp, skull, or brain. Her whole head suddenly became numb.
The numbness was accompanied by a twinge of pain. This pain did not spread throughout the entire head, but formed a strip that traveled through the head.
Then the pain became more severe, and the band became clearer, and Yuuhi Kurenai also felt the place where the pain finally gathered, which was the center of her forehead, and the pain there was far more intense than other places.
But along with the pain in her heart, she felt that her eyes had become cooler, and Sharingan needed less and less chakra.
Gradually, she refined the chakra that could keep up with the speed of consumption, and then the situation improved again, and Sharingan needed less and less chakra.
Until Sharingan could no longer absorb her chakra, and the numbness and tingling sensation on the top of her head gradually subsided, she shivered violently, and everything seemed to be back to normal.
She opened her eyes, and all the wonderful feelings brought about by Sharingan disappeared. She seemed to be back to the state of an ordinary ninja, but the Red Eye ball in the test tube beside her told her that everything that had just happened was real.
"You can try it and let the chakra focus on your eyes again."
Orochimaru did not directly untie Yuuhi Kurenai. He still had a lot of experimental data to collect, and asking her to read and open Sharingan was the first step in collecting these data.
Yuuhi Kurenai followed Orochimaru's request and let her chakra flow to her eyes. She frowned. The path of these chakra movements was not the same as at the beginning, but flowed to the place where the pain had just occurred in her brain. Then it gathered at her forehead and was divided into two parts and injected into her two eyes.
After injecting chakra into her eyes, she turned on Sharingan again.
"Now you should be able to freely control the opening and closing of these eyes. Give it a try--"
Orochimaru continued to guide Yuuhi Kurenai's behavior, and Yuuhi Kurenai also listened to his words and followed his instructions.
Starting from turning Sharingan on and off, they tried many projects in succession, and finally drained Yuuhi Kurenai's chakra completely before Orochimaru loosened all the devices that restrained her and released her from the experimental table.
"You cannot leave this base immediately. There are some experimental projects that have not yet been completed, and your current situation has not yet completely stabilized."
"And this is the first time I have done such an experiment." Orochimaru smiled softly and asked Yuuhi Kurenai to leave Laboratory.
Beside Laboratory was the place used for disinfection and changing clothes. Yuuhi Kurenai took off the pure white coat he wore during the experiment, put on his own clothes and shoes, and then sat in front of the mirror, preparing to touch up his makeup.
But when she looked up, she saw a horrifying picture in the mirror.
She raised her hand and touched her forehead. There was a particularly eye-catching mark there. On both sides of the forehead, there were lines from shallow to deep, from thin to thick, extending towards the center of the forehead.
In the center of the forehead, there is a pattern composed of three Tomoe. Although it is not very big, it is a particularly eye-catching bright red, as if it was painted on with blood.
Yuuhi Kurenai stretched out her hand and rubbed her forehead vigorously, but when she rubbed her forehead, it turned a faint pink color. The Tomoe lines on her forehead still stayed in place quietly. It seemed that they were not painted on, but integrated with her skin.
"Orochimaru!"
She stood up and angrily pushed open the door of Laboratory.
"What's wrong? Are you feeling uncomfortable?"
Orochimaru was still wandering in front of the instrument. He turned his head and looked at Yuuhi Kurenai who suddenly broke in at the door.
"What is this!" Yuuhi Kurenai pointed at the lines on his forehead and asked loudly.
A smile appeared on the corner of Orochimaru's mouth. He looked at his masterpiece up and down before explaining, "It is very easy to control Sharingan. You should know that if there is no bloodline of the Uchiha Clan, and Sharingan is not started by himself, it will continuously absorb your chakra until you die."
"In order for you to actively control the opening and closing of this eye, it took me a long, long time and made countless efforts."
"You should know that if Sharingan can be freely controlled by people who are not Uchiha Clan, these people would even be willing to have their bodies covered with various patterns."
"But..." Yuuhi Kurenai wanted to say something more, but was ruthlessly interrupted by Orochimaru.
"I have even paid close attention to the position of the marks. You only need to wear Forehead Protector to block all the marks without anyone noticing."
After the explanation, Orochimaru did not give Yuuhi Kurenai a chance to speak, nor did he want to explain the mark on Yuuhi Kurenai's forehead, so he directly asked her to leave Laboratory.
However, before Yuuhi Kurenai left, he still said something and asked her to go to Uchiha Jie's room. If there was a genuine Uchiha Clan person to help her, she could quickly become familiar with the abilities she had acquired.
Yuuhi Kurenai accepted Orochimaru's suggestion. There was nothing she could do if she didn't accept it. She left Laboratory and knocked on Uchiha Jie's door.
