Review Detail of eforos in Hero Cultivation

wow, i was binging reading the past 2 days, gotta say that the world building at start and the mystery was very interisting but it crashed in less than 30 chaps, the MC simply starts convincing people to joining him without any convincing, he just says come and people came... I don't see the MC being charismatic, and he gives no reason to... 1 time or 2 ok, but the way he convinced the grandmaster and was sure she was gonna obey was too forced, the number of 2D characters in this war arc was too much, all the kings and people in power are generic and simple forced to act simply to force a developtment, without convincing the reader... i guess the sin of the author was not to put a convincing insite of the characters thinking to make plauseble there actions... after this grandmaster being called vivi out of nowhere and became a obedient little puppy i just dropped... which is a shame since i liked the worldbuilding...
