Review Detail of DeeJack in The Ancient Genes

The Ancient Genes I only read about 20 chapters, I usually think this is not enough for a review, but I don't want to read more. I'll talk about what happens in those 20 chapters, so if you don't want to be spoiled, don't read. I won't use the spoiler tag because it's often used by the guys who only spam emoticons in the review. The MC is incredibly dumb and is only kept alive by the plot armor. In one of the first chapters, he was about to be killed but was casually thrown into his principal's house, so he was saved. When he gets into the academy, after the headmaster warned him to lie low, he tries to help the fatty when he gets bullied in the cafeteria. You can say that it's noble of him, yeah, that's if he could somehow help him. He's the weakest guy in the academy, had he tried to help him he would get bullied alongside the fatty and his days would be over. Thankfully, the plot armor saved him again. A couple of chapters later, he finds the fatty on the floor seemingly dead (obviously he doesn't check if he's actually dead) and swears to kill whoever did that to him, even if he had to die… Yes, this guy, the weakest in the academy, decided that he would use his own life to take revenge on someone who killed the guy he met the day before. Wow. I just can't stand people with a stupid hero complex, it would be a different case if he had the strength to back what he wants to do up, but he doesn't, he's just an idiot.
