Chapter 527: This is called a Sophisticated Scumbag_1

If the hallucinogenic injected into Qiao Xichuan was administered just before he entered the camp, then... the person who did it must be one of the eight people who returned.

No, that's not right...

Mu Weibai took a few people with him to UC, it could have been them as well.

In any case, it must be one of those people.

More and more clues were emerging. Although there was no specific culprit yet, Kang Chen felt... it was close.

...

Kang Chen was busy all afternoon, spending almost the entire time on the phone.

By the time he thought about going home from work, he realized that it was already past midnight.

If he went home at this time, he would probably arrive around two in the morning, and would have to head back after eating dinner. So, he decided not to go home.

He dialed a number to his home.

"Honey, I won't be home for lunch, have a good rest at home and don't be picky with your food, I'll be back in the evening."
