Inexplicable change in expression

Huang Liang came out with the Twin flowers and left a urine "sample" as boss Zheng had instructed.

Since boss Zheng had requested for the sample, Huang Liang did not neglect it. He personally took it and put it in the manager's office, then locked the door and went to work.

He greeted them from front to back. There were many important guests tonight, so he had to come out. After being busy for a few hours and being forced to drink a few bottles of beer, he finally had some time to rest.

Back in the manager's office, he sat on the chair and looked at the two cups of urine samples from a distance. He found it funny.

What did boss Zheng want to do with this thing?

Having been in the Jianghu for many years, Huang Liang had seen all kinds of new things. Boss Zheng, with his thick eyebrows and big eyes, looked like an honest and simple master, but he really had a lot of dark tricks behind his back.

Huang Liang smiled as he was tipsy.
