Before rebirth, he was the assistant of Mebius.

In the laboratory, Mebius first took the box containing the Herrscher core and placed it on the table. Then he took off the various instruments attached to Ling Feng and began to record something on a piece of paper.

When Ling Feng saw this, he thought the examination was over. Just as he was about to get off the operating table, he was stopped by Mebius.

"Little guinea pig, I haven't allowed you to come down yet." Mebius said while recording the data on the monitor.

"You're not feeling well yet?" Ling Feng said, lying down on the operating table again.

"It was just a small inspection and the experiment hasn't started yet. What? Is this unbearable?"

"You can take a nap first. When you wake up, the experiment should be over." Mebius said while still mixing something in his hand.

"No, I will stay here when I wake up anyway. I want to observe and see if there is anything in me that even you, Doctor, are interested in."

"Okay, let's use less this time. Don't fall asleep, little white mouse." Mebius smiled while injecting a higher concentration of anesthetic into Ling Feng's body.

Within five minutes, Ling Feng couldn't hold back his sleepiness and fell asleep.

"Little guinea pig, if you don't fall asleep, I won't be able to do anything."

"I hope your body won't be as disappointing as theirs."

Mebius stood at the door of the operating room and said to Klein in the hall.

"Klein, let's get started. Go get everything. And...remember to disinfect."

"Okay, doctor."

After a while, Klein came to the operating room with a container.

"Check the items again, Klein."

"By the way, have you told Cang Xuan and Danzhu that no one can enter the experimental area today?" Mebius said as he put on a mask and put on a new pair of gloves.

"We have prepared double the quantity of materials needed for the surgery. We have also told Cang Xuan and Dan Zhu that they will stop people who want to enter the experimental area." Klein replied.

"That's good." Mebius said with satisfaction.

"Okay little guinea pig, let's... get started."

The sharp scalpel fell on Ling Feng's body, but Ling Feng's skin had a weird toughness that made it very difficult for the scalpel to cut through his skin tissue.

Although Mebius tried his best to cut a small part of Ling Feng's skin, the wound healed quickly under the influence of Ling Feng's ability. Before she could do anything, the wound was almost healed.

"Klein, give me some diluted potion that suppresses Honkai energy and weakens special abilities." After trying for a while, Mebius decided to reduce Ling Feng's ability to a certain extent first.

Mebius took the test tube handed over by Klein, used a needle to extract some medicine from it, and injected it into Ling Feng's body bit by bit.

Soon, the parts of Ling Feng's injected body became like ordinary people. Not only could they be easily cut open by a scalpel, but the wounds no longer healed at a speed visible to the naked eye.

"No, Klein, dilute some more and give it to me. You must retain a certain degree of ability, otherwise it will be very dangerous in a while."

After receiving the order, Klein diluted the concentration of the drug again.

After waiting for a while, after the effect of this part of the medicine had almost disappeared, Mebius injected the further diluted medicine into Ling Feng's body. This time, the effect of weakening her ability finally reached her expectations.

"Alright Klein, give me the DNA of the Honkai Emperor."

Mebius took the genetic materials from Klein's hand and embedded them into Ling Feng's body bit by bit.

An hour later, Mebius put down the scalpel. Just as she had calculated, the potion that inhibited the ability quickly expired. The injuries on Ling Feng's body due to the fusion healed quickly, and the purple Honkai energy spread on the body surface. The lines slowly disappear.

On the screen nearby, Ling Feng's various life indicators were rising rapidly... Just one minute later, the indicators that had almost disappeared were almost close to the standards of a normal person.

Mebius stared at the data displayed on the screen. Now, as long as Ling Feng wakes up, the experiment can be declared a success.

But soon, the shortcomings caused by immature technology quickly launched a violent counterattack on Ling Feng's body. A large number of purple lines quickly spread to Ling Feng's body, and blood with Honkai energy continued to overflow from Ling Feng's seven orifices. The clean operating table was stained bright red.

The life indicators that were already almost improving dropped rapidly, reaching the critical value of death in just a few seconds.

The remaining resentment of the Honkai Beast pulled Ling Feng's consciousness into the abyss little by little, and even Ling Feng's ability to repair his body was greatly weakened at this moment.

"Klein, give me the high-concentration Honkai energy reagent." Mebius said. After getting the reagent from Klein, he quickly injected it into Ling Feng's body.

Mebius stared at the indicators on the instrument. As long as they showed a downward trend, Mebius would give Ling Feng Honkai Energy.

This situation remained deadlocked for half an hour. After injecting nearly ten times of reagents containing high monstrous energy, Mebius snatched Ling Feng back from the grasp of death.

It's a pity that the experiment failed. According to the testing of the instruments, most of the Honkai Emperor's DNA in Ling Feng's body was destroyed by his repair ability, so Ling Feng's life was barely saved.

"The experiment failed." Mebius said in disappointment. She put down the reagents in her hands, took off her blood-stained gloves and sat on a chair in the corner of the operating room to rest.

"What went wrong? Obviously the compatibility between the mouse and the Honkai Emperor is as high as 30%, which is the highest among all those tested so far, but why?"

"Is it because of his ability? No, no, the ability of the white rat is more towards 'devourment' and 'assimilation'. Theoretically speaking, the ability of the white rat should increase the success rate of the experiment at the end of the experiment. "

While Mebius was thinking, and while Klein was cleaning up the operation site, Ling Feng slowly opened his eyes and slowly sat up from the operating table.

"Ling Feng"'s move shocked Mebius, because according to the time she calculated, Ling Feng would not wake up until three hours at the earliest.

But just a short time later, Ling Feng had already sat up.

He looked around the operating room, and the golden pupils that should have been like the core of Herrscher of the Sky turned into a bright red for some reason.

"Little white mouse, you woke up so soon?" Mebius said, preparing to get up and remove all the instruments still attached to Ling Feng's body.

"Ling Feng" raised her right hand to hold her forehead, obviously still a little uncomfortable with it. Looking at Mebius who was slowly approaching her, she said sternly.

"Don't come any closer, human!"
