Freya understood Xu Yan's confusion and smiled. "Dr. Xu, you may not know that before we transferred you and A Xin, Bradley and I had already been lurking in the laboratory. So, this isn't actually the first time we've met."

Xu Yan narrowed his eyes.

So when he was in the laboratory, he always felt that someone was watching him. It wasn't just an illusion?

"Also, Cheng Min, the adopted son beside Bai Zhanwang, was one of our people." Freya knew that Xu Yan had many doubts. Besides, this person had been controlled by Bai Zhanwang for years and was extremely wary. If they wanted him to confess everything, they had to build a relationship with him gradually.

Xu Yan suddenly realized. "No wonder Cheng Min deliberately got close to me for a while. I thought Bai Zhanwang sent him to monitor me, but it turned out he was one of yours."

"That's right." Freya smiled again.

Bradley, who was sitting beside her, saw that she had been staring at Xu Yan and had even smiled twice during their short conversation. This made him extremely jealous.

Immediately, the hand that was under the conference table slowly reached over and domineeringly grasped her wrist.

Freya turned her head to look at the man and noticed that his face didn't look very good. She immediately squeezed his wrist in return and unexpectedly checked his pulse.

His heart rate was beating very fast, his breath was a bit unsteady, and he even seemed a bit impatient.

Could he be sick?

She used her finger to gently write in his palm, "What's wrong? Where do you feel uncomfortable?"

Bradley only felt a tingling sensation in his palm, as if duckweed was brushing against his heart, quickly causing ripples in his heart.

He naturally knew what she was writing. Soon, he wrote a sentence in return, "Don't smile at others."

Freya was stunned for a moment.

But she quickly understood. This man was indeed "sick," and it was a "jealousy illness" that only she could cure.

She smiled helplessly and wrote again, "I'll listen to my husband."

Bradley felt her little gesture and the tender look in her smiling eyes that was only gentle towards him. Suddenly, his mood improved a lot.

The two of them were writing and expressing their affection under the table, and Xu Yan had already noticed it with his sharp eyes.

But he didn't expose them. Instead, he pretended not to see anything and said, "Anyway, I still have to thank the Dark Master and his wife for saving my wife and child. I will always remember your great kindness for the rest of my life."

Only then did Bradley retract his gaze and regained his usual cold demeanor. "In that case, Dr. Xu, please tell us everything you know. That would be the best way to repay us."

"What do you want to know?"

"Well, that depends on what you can tell us, Dr. Xu." Bradley leaned back in his chair, looking at the other person lazily.

Xu Yan smiled faintly. "Before I was captured by Bai Zhanwang, I was just an ordinary researcher in an institute. Apart from doing various research every day, my life was extremely simple. Later, I was captured and brought to the underground laboratory. For all these years, I've been researching the beastly venom here. I really don't know what the Dark Master wants to know!"

Bradley crossed his hands. Suddenly, he leaned forward, placed his elbows on the table, and his cold eyes fell on Xu Yan. "As far as I know, your master once worked for the Zhan Fa family. Your master played a significant role in the development of the snake Poison of the Zhan Fa family."

As soon as these words were spoken, Xu Yan's face turned extremely ugly.

Even his eyes looking at Bradley were filled with disbelief.

"How do you know that?"

Bradley tapped the table twice and said indifferently, "This is the Dark Web. Do you think it would be difficult to investigate someone's information?"

When they were approaching Xu Yan before, Bradley had asked Ying to secretly investigate Xu Yan's background. Unexpectedly, such a major clue was uncovered.

Xu Yan's master, Yuan Songbai, was an expert in toxicology. He was good at using poisons. He used to be the director of an institute. However, due to his evil intentions, he developed various poisons, causing many people in the institute to be poisoned. As a result, he was fired from the institute.

Yuan Songbai didn't stop there. Instead, he changed his name and joined the Zhan Fa family, and had been researching poisons for the Zhan Fa family.

But he didn't expect that the Zhan Fa family was so cruel. After he developed the snake Poison, they actually used him as an experiment. Yuan Songbai couldn't withstand the erosion of the snake Poison and eventually died from the poison.

Xu Yan's body trembled uncontrollably twice, and he said in a hoarse voice, "Even so, I've already severed my relationship with my master. I don't know anything about him."

Xu Yan thought that his identity was very well-hidden, and even Bai Zhanwang couldn't possibly know about it. But he didn't expect that Bradley had dug it out.

Yes, Yuan Songbai was his master.

But after his master used poison to harm many innocent people, Xu Yan severed their master-disciple relationship and established his own research institute.

He thought that he would never hear the name "Yuan Songbai" again in his life, but unexpectedly, he heard it from the Dark Master.

"No, Yuan Songbai once sent you a formula for a poison Poison. When you were working for Bai Zhanwang, you combined the formula of the poison Poison with that of the beastly venom, causing the beastly venom to mutate.

Although injecting the venom won't be fatal in the short term, the toxin will gradually spread to the internal organs. Eventually, normal people will lose their minds, become manic and bloodthirsty, and gradually move towards death."

Freya pushed a piece of information in front of Xu Yan and asked again, "Am I right, Dr. Xu?"

Just after coming out of the dungeon, Freya went to the testing room.

She didn't expect Yun Xiangcheng to be so fast. He had analyzed the components of the beastly venom in the shortest possible time.

What surprised Freya the most was that the new type of beastly venom actually contained the toxicity of the snake Poison.

Just then, Ying came to report on Xu Yan's situation. Freya combined the two and then boldly came to this conclusion.

Before, it was just a suspicion. But now, seeing Xu Yan's incredulous expression, Freya knew that her guess was correct.

Xu Yan's hand holding the information was trembling slightly. Finally, he lowered his head dejectedly and said, "You're right. My master did send me a formula.

Back then, my master knew that the Zhan Fa family wouldn't let him go, so he secretly recorded the formula and gave it to me. Not long after that, my master was killed. This formula was too evil. I couldn't figure it out and didn't dare to use it randomly.

It wasn't until Bai Zhanwang captured me and brought me to the underground laboratory and asked me to research the beastly venom that I tried to use the snake Poison to destroy the original toxicity of the beastly venom."

Freya listened to him carefully and finally said, "What about the formula of the snake Poison?"

Before, in the underground laboratory, Freya had been poisoned by the snake Poison. If it wasn't for Qin Gou's research on the antidote in the end, she might have died from this poison.

The toxicity of the snake Poison was no less than that of the beastly venom, and this poison also had to be completely destroyed.

Xu Yan said, "After it fell into Bai Zhanwang's hands, I was worried that the formula would be leaked, so I burned it."
