Chapter 215: A dark cloud upon humanity

On this dry wintry day, Tong Lili was finally able to return home and rest under her own blanket after working for more than 30 hours in a row without sleep. Although she felt all sorts of dissatisfaction and unwillingness, her eyes would no longer open after becoming red and swollen from crying. She was far too tired.

Zhang Fan was also really tired. The 24-hour work shift plus having to concentrate for several more hours afterwards to perform surgery also made him feel rather dizzy. He closed the curtains in his apartment and took a hot shower. Thanks to the heating system, he didn't feel cold in his apartment at all. The chilly air outside didn't penetrate his apartment.

Winters in the border province were truly freezing. Currently, it was below -30 degrees Celsius. Any water particles in the air would instantly freeze into frost. The dry and cold temperature was also the best type of environment for viruses to grow in.
