Review Detail of Labrenyth in Monster Integration

MC from Super weak to weak. If you want MC that always gets abuse this is for you. He trains months and years but his strength? Fking trash this Novel MC is for masochist only. Im not expecting the MC to be op suddenly but atleast give him some brains so that he can think when he is fighting stronger than him all he do is willpower i can get through this!! Fk this plot armour he suddenly levels up when he is dying. So everytime he is dying he suddenly levels up but when he trains months or year nothing happen he just understand more of his skills and weakness. But when he goes to fight his brain will suddenly die and all he thinks is will power so that he can go through everything.
