Comments of chapter undefined of I am a Problematic Dungeon Master

Lets go back in time a bit. Their allies were attacked and Ein took off on a wolf that ran so fast that it could run above the tree crowns of the forest, forcing him to cling on for dear life while experiencing a few G-forces for a few hours, once he arrived, he went crazy with his manablade until he fainted, a few hours later the dungeon was in danger and woke him up, he shared some of his mana with the wolf then teleported back to the castle for a death match with the paladins. After having all of his mana explode and nearly ripping him apart he went around killing all the intruders until he finally got exhausted and left it to the wolves, he then went inside and heard of the situation in Bestia, teleported over inside a sanctuary that hurt him and his mana non-stop, using his mana again to cut off the leg of the dragon before dismembering him to the core and finally kill the dragon. Later on, after he dumped Michelle, filled with poison, festering wounds, out of mana and simply exhausted after the attack from a higher being from hell/chaos, he decided that all she needed was sleep and went to practice/ play with magic. And this guy walks around like there is nothing wrong with him, despite not even stopping to rest even once during these 48 hours or so where both his mana and mind were allowed to properly rest. I know that the dungeon made him semi-immortal butcome on, stop abusing your MC like this will ya? :P
