It was fortunate that the wrath of men couldn't last for long with how easily distracted they were by the fight that was happening.
So, Ning managed to get out of the situation without making too many attackers.
He fought the warrior a few more times, long enough for him to realize what was happening.
'He gets stronger the lower his HP is?' he thought. That was the only explanation. And with HP regeneration being reduced by 80%, the man wasn't healing as much and was thus getting stronger by the second.
'Shit! I really can't do this,' Ning thought and slowly backed off into the fighting demons until he was side by side with them.
"This man is trying to go for the commander, kill him!" Ning shouted at the demons, and successfully managed to grab the attention of 2 demons who joined him to fight.
