Purification 

No zombie hit the door, the countdown in the task prompt bar stopped at 15 minutes and 20 seconds.

"Foreign people, come out." Wu Gang knocked at the door. It's time to hand in the task and get the experience.

The words sound just fell, and the cabinets blocked on the door were removed one by one. This detail made him smile a little. Whether the cabinets were blocked on the emotional door or not is the key variable that determines whether the people inside can survive.

A blonde Russian girl opened the door. Wu Gang couldn't help sighing that seeing is better than hearing. Russian girls were really beautiful when they were young.

Still, struggling with how to say hello in Russian? He was hugged by the foreign girl half a head taller than him and kept chanting something over and over again in Russian.

Wu Gang patted her on the back and said, "so sorry I come here late and you must be frightened."
