Despite the sneak attack, Mo Awu's attack was very effective. Be it by him impaling the opponent's heart, or by the flame arrow that hit the old man's chest, the black-robed old man was severely injured. This time, instead of spraying out black fog, the old man gushed out black and greyish blood.
"Big Brother!!!"
The other black-robed old man immediately waved his magic staff upon seeing his situation, creating a giant tiger made of black fog that forced Mo Awu to have no choice but to retreat to Tang Xiu tens of meters away.
The old man didn't pursue, and instead quickly took a porcelain bottle out from his inner pocket and retrieved a gray-black pill from the inside, forcefully stuffing it into the injured old man. A black fog was then released from the slit of his fingers and constantly fused into the injured old man's heart.
