Review Detail of Samhain666 in Invincible Divine Dragon's Cultivation System

I'm very much enjoying this novel, the supporting characters are good, the bad guys are typical but still enjoyable, the only problem I have is sadly with the MC he is strong and ends up with all kinds of techniques, but he in my opinion is very much like a coward, he hides in the back all the time unless is very forced to do something or just complains he doesn't have the time and runs away, and after a certain point he just completely became complacent and stop upgrading his on strength, it really makes me sad cause otherwise it would be almost a 5/5 novel for me...
