Three days later.
In a biological laboratory on the outskirts of Johannesburg, South Africa.
At this moment, it's already three o'clock in the morning in South Africa, while back home, it's exactly nine in the morning. Just now, Zhao Heng and Xu Man Ni had a videoconference with their parents.
Since arriving at this laboratory in South Africa two days ago, Zhao Heng has almost been in daily contact with his family through video calls.
Having been here for two days, Zhao Heng is still adjusting to the time difference, and despite it being the early morning, Zhao Heng feels no drowsiness at all.
Back home, there were two other experts who arrived as well, both of whom are epidemiology specialists.
Moreover, this biological laboratory is not the kind of laboratory in the ordinary sense. To call it a laboratory is less accurate than calling it a camp, with researchers sleeping in tents.
