The next day.
Three o'clock in the afternoon.
The entrance to the Life Science College Experimental Area.
Zhao Heng was carrying a white biological sample transport box in his right hand, containing a spinal sample. In his left hand, he carried a laptop bag, with Sun Xinxin's examination records inside the laptop.
However, just as Zhao Heng reached the entrance to the experimental area, a security guard stopped him. This was a national-level biological experiment center, and naturally, not just anyone could enter.
"Hello, I am Zhao Heng. Professor Li Hongwei asked me to come."
Zhao Heng politely told the cool-looking security guard.
"Professor Li Hongwei?"
The security guard looked at the young Zhao Heng, a bit puzzled, because Professor Li Hongwei was an absolute authority in this experimental area, and he generally only worked with PhD candidates. Seeing Zhao Heng, who appeared to be in his early twenties, naturally aroused the security guard's suspicion.
