National Copy: I Am Really a Priest

Fang Jue traveled to a world where everyone played dungeons, and awakened the reverse operating system. As long as he practiced hard, his strength would decrease. On the contrary, if he fished hard, his attributes would improve all the time. Boss is too strong? It doesn't matter, he will bleed immediately after I give him milk! Teammate wants to die? Do you want to know how to restore blood with a slap in the face? Monster siege? I will start the group directly with my body and get unlimited blood recovery!
