Review Detail of DaoistuFSwDO in New Age Of Summoners

Phew, I can't understand how a protagonist can be such a mindless, idiotic wretch like what we see in this story. I really can't fathom it. Why do you have to make such a 0iq character? It would not be possible to make a sensible protagonist who does not just do everything according to a whim, even when life is in a death situation. I can't understand the parts when there are big fights and the main character just sits to the side and reads the system and everything as if he were on a picnic
