We are their slaves. Why did you say these two words when you came? !

This is not difficult to understand. Ten seconds after the game starts, the virus should randomly choose the player as the host. After the selection is completed, the host will become a female zombie, while the virus host has lost consciousness and is completely controlled by the virus, so the virus becomes its own "master", so "we are their slaves."

"They are coming" is what the host said after selecting the virus. It is the host who warns other humans with the last remaining consciousness, which means "the virus is coming."

"They are back" is what God said after sleeping, and it is also the best to understand. The virus in the host brain causes the cells to re-sit and resurrect, and the sentence of slapping the head will not appear again.
