"One day, by chance, I heard from my dad that someone had obtained a very mysterious substance that could make the human body evolve. Then these laboratories have been conducting research on this substance."

"Then there was an accident in the lab, and it was quite a big deal. We had a small party at home that day, and my dad was hurriedly called away. So I have a very deep impression of it."

What Liu Wenrui said reminded Li Wenbin and Liao Hongxuan of a piece of news in S City.

Li Wenbin asked, "More than a year ago, a fire broke out in the Central Hospital of S City. Is it related to this incident?"

The official explanation at the time was that the weather was dry and someone accidentally started the fire while smoking, but the public did not believe this explanation.

According to insiders, the fire started in the morgue of S City Central Hospital. The morgue is the coldest place in the entire hospital. How could anyone smoke in such a place?

Now it seems that this fire may not have been an accident, but someone may have set it on purpose.

Something must have happened that caused them to set fire to cover something up.

Liu Wenrui coughed twice and spat out a mouthful of blood, confirming Li Wenbin's words.

"You're right. I've always been curious about this matter. After the hospital caught fire, I heard my dad talking on the phone with someone in his study."

"He asked if the substance would spread after it was burned. I don't know what was said on the other end of the phone. My dad then said, 'Don't worry about the rest and just continue researching.'"

"Then he hung up the phone."

"For more than a year, I didn't hear any news from my dad about the lab because he rarely met me and even seldom came home."

Finally, after telling everything he knew, Liu Wenrui took a breath and saw Teng Linxu took out the dagger again. He quickly supported himself and moved back, saying anxiously,

"I've told you everything I know, without hiding anything! You can't go back on your word!"
