- Description from novelbuddy

The Virgin Mary system dug out a delicate girl, Chi Ying, from the game world as its host.

Looking at her pure face, it secretly affirmed in its heart that this pure appearance simply best suited the Virgin Mary character!

After binding, it discovered that the delicate flower was in fact the villainess boss of the game!

The system was faintly worried: Yes, it should be fine, right?

The system saw Chi Ying standing in a pool of blood, with the light of the Virgin Mary above her head, holding a zombie’s head and weeping.

She burst into tears, “God, they are so pitiful.”

Everyone: Is this person sick?

Seeing the ever-increasing Virgin Mary value, the system covered its eyes.

Don’t think I didn’t see it! Weren’t that bunch of zombie heads all cut off by her?!

Gu Chi picked out a woman from the pile of zombies, with tears in her eyes and blood all over her body.

He reasonably suspected that she was a dangerous person who had been infected, so he tied her up, and put the gun against her eyebrows, waiting for her to mutate at any time.

The woman he pointed the gun at suddenly turned her head, which seemed to be a sign of mutation. Gu Chi looked resolute, and was about to shoot when he saw her looking at him lovingly, she said, “You are so ruthless, you must have been hurt in the past… It’s okay, I don’t blame you.”

Gu Chi shook his hand.

“…”

Thank you for the invitation, but he didn’t get hurt before.
