"Hey bro, let's have a competition to see who can kill the most mutant rats. The loser has to call the winner 'Big Brother'."

Chen Zhe grinned and said, "Okay, let's begin now."

Gu Qingqing was speechless. What kind of time was this to be thinking about bets?

Ye Yunxi and Fu Heng didn't interfere; it was a matter between them, and also a matter of friendship between men.

Xuan Yu and Chen Zhe were seen desperately attacking the mutated rats, swatting at each one that pounced on them. They didn't care who the rats bit; they just wanted to kill them first.

The two fought and counted, and a few minutes later, they had dealt with all the mutated rats around them.

Chen Zhe said to Xuan Yu with a smile.

"Brother Xuanyu, I killed twenty-two, how about you?"

Hyun-woo smiled smugly.

"I have five more than you, so you have to call me Big Brother!"

Ye Yunxi raised her hand and smacked Xuan Yu on the head, saying with dissatisfaction.

"Don't call me 'Big Brother,' you're getting carried away. We've finished here, but there are others elsewhere. Let's hurry and find Master and Dr. Hu."

Xuan Yu rubbed the spot where Ye Yunxi had hit him and said with a wronged expression.

"This is a bet I made with Chen Zhe!"

When Gu Qingqing and the others saw Xuan Yu being beaten by Ye Yunxi, they chuckled quietly.

Chen Zhe looked completely innocent and spread his hands as he spoke.

"This is not my fault."

Ye Yunxi glanced at Chen Zhe and rolled her eyes at him and Xuan Yu.

He turned to Zhang Haiyi and asked.

"Haiyi, did you drive here?"

Zhang Haiyi replied, "It's open. The car is parked up ahead."

Ye Yunxi nodded. "Then let's hurry up and go. I'm worried that Master and the others might be in danger."
