It took Zeru less than a microsecond to unleash his sword. Before Jin could finish blinking, his master had already inflicted him with hundreds of superficial cuts on his flesh, from head to toe at a distance. The cuts were too numerous to be counted, and Jin staggered instantly.

"Hey! I just healed him! Can you be a bit more gentle?!" Pei shouted through the System Channel at Zeru though he shook his head in defiance.

"In a fight, not giving your all is not just a sign of disrespect towards your opponent, it may also be the one mistake that might reverse the tide of battle," Zeru replied, giving Jin barely enough time to close his wounds with the aid of Octofussy's Rapid Regeneration of the Otherworld Parasite God.

Regrettably, there was no free meal in the world. Jin could feel a tingling sensation whenever his flesh wounds healed. It was as if a worm crawled over his wounds to treat them.
