Ren Qing entered the mine tunnel and buried himself in excavation.
After the Human Skin Book advanced to the Half-Corpse Realm, he clearly felt that the recoil from the Great Miao Saber striking the stone wall had weakened.
This allowed Ren Qing to dig without restraint. Even if the web between his thumb and forefinger split open, he could shift the damage elsewhere, raising his efficiency to another level.
