When Ning Yu came to Lin Hao's office again, she found that the documents on his desk had obviously become fewer, and she vaguely guessed something.

"Has your management system already been implemented?"

Ning Yu suddenly appeared behind Lin Hao, who was typing something on his notebook.

Hearing this familiar voice, Lin Hao turned around and adjusted his glasses:

"Yes, now I finally have time to continue studying the serum."

"Since you asked me to come, there must be some new progress?"

Ning Yu slowly walked closer and saw that he was already operating his laptop and started running commands on it.

A large number of characters and charts were moving and flashing, and Ning Yu couldn't understand them, but soon, an audio player popped up.

"Experiment number UT-3771, cyborg degree 39%, failed."

A man's reporting voice was heard in the audio, and he seemed to be entering information into some kind of system using voice input.

"I don't even know how many experimental subjects this is this month."

The man was talking to himself. Ning Yu was not unfamiliar with this voice. He was the man called William in the recording analyzed last time.

"Lacey, do you think I'm really on the right track?"

William's voice sounded a little depressed, as if he was in some kind of self-doubt.

"Of course, Lord William, I am your best proof."

The extremely familiar girl's voice was heard again in the recording, and she seemed to be comforting William.

"Warning: An abnormality has occurred in laboratory A13. The laboratory door has been severely damaged."

Another mechanical prompt sound came from the recording, and it seemed that something unexpected had happened.

"Damn, that question again."

William seemed to be in a bad mood to begin with, and now he couldn't help but complain.

"I'll take care of it for you, you take a rest."

Lacey seemed to stop William who was about to do something.

Then, all that was left in the recording were some noisy metallic sounds, the sound of something exploding, and some familiar howling.

Ning Yu was sensitive enough to notice that this voice was so familiar that it could be heard everywhere in the apocalypse. It was the sound made by zombies.

After listening to the recording, Ning Yu looked at Lin Hao and said, "It sounds like the source of the T virus you are looking for seems to be related to this William."

She was finally convinced that the disaster must have been man-made, not a natural disaster.

Lin Hao did not answer Ning Yu immediately, but said in a tone that neither confirmed nor denied: "Don't worry, the serum you brought back last time has added a lot of information."

He entered a number of incomprehensible commands, and a new recording popped up.

"What are you talking about?"

William's angry voice came from inside.

"William, don't worry, listen to me"

A strange man's voice came from inside, gentle and calm, which was in sharp contrast to William's attitude.

But before he could finish, he was interrupted.

"I repeat, I have no interest in your so-called rituals, roots, or magic."

William said a few words in succession. Although I couldn't quite understand them, he seemed to be rejecting the strange man.

"William, our goals are not in conflict, we can just change our methods a little bit."

The strange man didn't seem to be angry at all because of William's attitude.

"If you weren't the teacher's son and my good friend for many years, you would have been kicked out by now. Do you understand what I mean?"

William didn't seem to want to talk to him much.

"Please don't bother me anymore."

He said it in a decisive tone.

"William, don't you want to know the truth of this world? Don't you want to understand the ultimate truth? Once you get there, all the problems will be solved..."

The strange man seemed to want to persuade William.

"Let me ask you, if it is really as you said, then why didn't anyone who went there come back?"

William was totally unmoved.

"I'm not interested in the vague things you're talking about. Put away your tricks."

"Lacey, ask him to leave."

He seemed to have no patience anymore and ordered them to leave.

"Yes, Lord William."

Lacey responded immediately.

The recording stopped abruptly here. Ning Yu was confused. She looked at Lin Hao with a puzzled look and asked, "Did you get any information?"

In this recording, Ning Yu only heard someone who seemed to disagree with William and was trying to persuade him.

But she heard a very familiar word, "roots."

When Ning Yu first awakened her origin ability, she seemed to read this word from Yue Ji's mouth shape, but had no idea what it meant.

"I thought you would know. Magic? Rituals? Origins? What are these?"

Lin Hao waved his hands, indicating that he was a science student and an atheist, and he had no idea about such superstitious things.

There are many things about Ning Yu that cannot be explained by common sense, and Lin Hao thought that Ning Yu would know something.

"I don't know, but I feel like things are becoming more and more complicated."

Ning Yu narrowed her eyes and sorted out the clues in her mind.

"Okay, if there's any further progress, I'll contact you again."

Lin Hao saved the files and then seemed to start working again.

"Well, I will try to find more serum."

Ning Yu responded.

Ning Yu returned to the apartment and sat on the sofa, still thinking about the information he had just received.

"Xiaoyu, what are you thinking about? You look so sad."

Shen Yiyue seemed to have finished cutting the vegetables in the kitchen. She had just taken off her kitchen apron and walked over to sit next to Ning Yu.

"Hmm? Have you prepared all the dishes?"

Ning Yu did not answer this question directly, and planned to discuss it with Shen Yiyue later.

"Yes!"

Shen Yiyue nodded, walked over and leaned next to Ning Yu to carry out her daily care.

"By the way, Xiaoyu, when is our next training?"

When Ning Yu heard her words, he turned around and looked at Shen Yiyue in confusion, and saw that she was not looking at him, but had a sharp gaze, and he didn't know what she was thinking.

"Why do I feel like you've become particularly enthusiastic about training recently? You used to be too lazy to go."

She looked at Shen Yiyue with suspicion and found that Shen Yiyue still didn't look at her.

"No, didn't Xiaoyu say last time that she wanted to become stronger? Then I also want to become stronger so that I can stay by Xiaoyu's side~"

Shen Yiyue finally turned around, looked at Ning Yu with a smile, and began to explain.

"Really?

Ning Yu asked.

"Of course~~"

Shen Yiyue nodded seriously and looked around. Shen Qianqian was still in the room.
