The laboratory here is not like the shared Animal Experiment Building; it's locked when no staff are present. Duan Sanbao carries a key to the mentor's office, suggesting that when Doctor Cheng mentioned he was tired and sleeping in the lab, he was actually in Immortal Brother's office.
Before reaching the destination, they encountered Dr. Han in the corridor.
Is it a coincidence? Hard to tell. Repeated chance encounters make it seem like they have some kind of fate with Doctor Mu Yongxian.
Duan Sanbao felt tense; he is not Doctor Cheng nor Boss Cousin, and he is unsure how to handle competitors while accompanying a group of young students.
"Hello everyone." Dr. Han greeted them warmly, "Here to visit the teachers' laboratories, right? Want to take a look at our Dr. Mu's lab?"
"Yes." Wei Shangquan raised his hand.
The other students looked at him in surprise.
