At this moment, Cheng Youlin was on the computer, chatting with someone on WeChat through the client.
"Great! I can go on a mission with Qu Lianhong again tomorrow," Cheng Youlin clenched his right fist and swung it vigorously.
"What's got you so happy?" Mu Rufeng stood behind Cheng Youlin, grinning.
"Who!" Cheng Youlin's heart skipped a beat, and several threads shot out from behind him, striking Mu Rufeng.
But, those threads sharp enough to slice through iron didn't even cut the edge of Mu Rufeng's clothes.
Are you kidding? His clothes were the Level 9 item "Heavenly Silkworm Silk Robe," and they sure weren't lacking in defensive power.
"Mu Rufeng! How many times have I told you, next time you come in, knock on the door first. Don't just appear in my office."
Cheng Youlin quickly hit the Alt+Tab keys, then stood up, looking angrily at Mu Rufeng.
