Xie Xuan felt that Dr. Song was just playing on her nerves.

But she knew that even if she questioned Dr. Song why he did this, she would probably only get a response like "It is necessary to make some sacrifices for science."

So she controlled her emotions and didn't follow Dr. Song's line of thought. Instead, she asked, "What experiment do you want to do with me?"

Dr. Song said, "I can't tell you right now."

Xie Xuan didn't ask any further questions and said directly: "I can do this experiment with you, but before I cooperate with you, you have to pay me the promised reward first."

Dr. Song smiled and nodded, "Of course. You want to know where the thing that controls Director Li is, right?"

"Yes." Xie Xuan said.

Dr. Song said readily, "When you came in, you should have seen the tallest building in the middle of the park. This thing is on the top floor of the tallest building."

Doctor Song's answer was too easy, which made Xie Xuan and the others a little suspicious.

"If you lie..." Yu Wu was interrupted by Dr. Song before he could finish his words.

"There's no need for me to lie to you," Dr. Song said. "I wasn't with them in the first place. Since we weren't companions, there's no question of keeping secrets or betrayal."

Xie Xuan guessed that the "they" Dr. Song was referring to was Paradise Lost.

"I can have Xiao Yu take you into the building. As for what you plan to do next, that's up to you." Doctor Song said, spreading his hands. "It's a fair deal, isn't it?"

Chongming turned to look at Xie Xuan. This deal sounded fair.

However, the experiment that a person who has conducted so many cruel human experiments in District 6 wants to use on Xie Xuan will definitely not be an experiment like lactose tolerance. For Xie Xuan, this deal is not fair.

"I agree." Xie Xuan stood up and said, "Let's get started now without further delay."

Dr. Song smiled and said, "Very good. Let's go."

However, after saying this, Dr. Song did not leave in a hurry. Instead, he asked Xiao Yu to take Chongming and Yu Wu away first.

Chongming could only say to Xie Xuan: "Be careful."

Xie Xuan said: "You too."

After Xiao Yu took Chongming and Yu Wu away, Dr. Song opened a bookcase, revealing an elevator behind it.

So in the final analysis, laboratories still prefer to be built underground.

Doctor Song politely made a gesture of invitation, and Xie Xuan didn't want to waste any more words with him, so she walked in.

There are only two buttons in the elevator, one for up and one for down.

Dr. Song pressed the button. This elevator probably only stopped at the underground laboratory and the office floors above ground.

Xie Xuan had no desire to communicate with Dr. Song, but Dr. Song asked Xie Xuan about her special abilities with great interest.

Xie Xuan didn't want to answer, so Dr. Song asked and answered his own questions.

But what surprised Xie Xuan was that Dr. Song, whether he guessed or found out through some other channel, described a supernatural power that was actually similar to hers.

"Don't be surprised, I was also involved in your original project." said Dr. Song.

Xie Xuan didn't fully understand the truth of what happened back then. Seeing the confusion in her eyes, Dr. Song kindly explained, "You are one of the results of the collaborative project between the Ecological Organization and Noah Technology eighteen years ago. Back then, Noah Technology provided the Ecological Organization with a batch of gene-edited humans—oh, clones of Xie Yuheng—for infection experiments. I had just graduated and joined the laboratory at the time, and I was the junior researcher responsible for recording your data."

The missing truth was basically filled in at this moment. After that, the cooperation between the two companies broke down, and she returned to Noah Technology, and was implanted with a part of Bai Ze. However, the two strains of bacteria could not coexist peacefully in one person's body at the same time, so her devouring ability went dormant, and Bai Ze's evolved system took control.

So, are her memories of traveling through time still real? Or is this just a false picture created for her by the system in the database?

But at this point, none of this matters. After all, she has no attachment to her life before traveling through time, and in this world, she at least has several blood brothers and sisters.

Although Xie Yuheng, who provided her genes, is now no different from a dead person.

Dr. Song was somewhat disappointed that Xie Xuan did not lose her composure as he had imagined.

But when the elevator reached the floor, Dr. Song regained his spirits.

This place is underground. Xie Xuan estimated that it was at least on the fourth floor underground. When she walked out of the elevator, the scene outside was somewhat similar to the fourth floor underground of the hospital.

But the rooms here were all made of transparent materials, and were filled with transparent boxes filled with solutions that she had seen in the hospital, but the bacteria in the boxes here were all alive.

The colorful, large and small fungi sway their mycelium in the solution like a ball of seaweed, giving an indescribable sense of weirdness.

There were a few people in the room, but their behavior was the same as the people Xie Xuan saw behind the front desk. They stared at her closely, but did not move, and their expressions were also very dull.

Dr. Song seemed to prefer the room at the end of the corridor, and this time he also took Xie Xuan into the room at the end of the corridor.

This room was also transparent. Before Xie Xuan entered, she saw a fungus species as big as an entire wall.

Xie Xuan had seen such large fungi before. In the leech field outside the wall, she even went in to experience the feeling of being completely wrapped by the fungi.

But this strain, or this pile of strains, is different from the leech strain. This strain does not grow to this size, but is artificially mixed together.

It's like buying a box of slime and then mixing all the different colors of slime together without pulling them evenly.

The fungus that covered the entire wall was just such a mixture, and it didn't even look as shocking to Xie Xuan as the leech fungus outside the wall that was beating like a heart.

Therefore, when Dr. Song was fascinated by his masterpiece and planned to show off to Xie Xuan, he found that Xie Xuan's expression was boring, as if she was looking at an unremarkable oil painting.

Doctor Song's expression was ferocious for a moment. "Don't you think it's beautiful?"

"I don't think so," Xie Xuan said. "If you think this is beautiful enough, you really should go outside the wall and take a look. I've seen one that was big enough to wrap me up completely. It was blood red and beat like a heart, and every strand of mycelium inside was like a leech."

Seeing Dr. Song fascinated by her description, Xie Xuan smiled and said, "Compared to nature's masterpieces, your work can only be described as ugly."
