6 PM.
Finally, Zhao Heng finished a very busy day at work.
Sitting in the chair, Zhao Heng stretched lazily, stood up, changed out of the white coat, and ate something simple in the canteen.
However, instead of going home, Zhao Heng continued to head to the Yanjing University School of Life Sciences.
At 7 PM, Zhao Heng arrived at the entrance of the Yanjing University School of Life Sciences.
The security guy saw Zhao Heng and just nodded, letting him in.
Lately, Zhao Heng had been coming here quite often, so the security guy already recognized him.
Seeing that the security didn't say anything and just let him in, Zhao Heng felt pretty good.
Am I now someone who can just show my face?
Zhao Heng couldn't help but think.
Arriving at Laboratory One, Zhao Heng found that only Professor Li Hongwei was there.
At this hour, it's estimated that everyone else had already left for the day.
Professor Li Hongwei was truly dedicated, working overtime here alone.
