Actually, he really can't be certain whether this virus will mutate again in the future, but based on the current situation, Xiao Yifei has effectively controlled the virus. Otherwise, he wouldn't dare to easily place the pathogen into Sun Xingyao's body.
The next day after work began, Sun Xingyao specially brought a big box of items to Xiao Yifei's office and said, "Dr. Xiao, these are some specialties from my hometown, which my mom sent yesterday. I've brought some for you to taste and hope you won't find them unwelcome."
Xiao Yifei saw Sun Xingyao proactively coming to offer goodwill and was happy to oblige. Xiao Yifei is a kind-hearted person who generally doesn't hold grudges, allowing him to live relatively lightly. Unlike some people who scheme all day about how to harm others and gain minor advantages.
