Review Detail of Higgs in I’m Cultivating Immortality While Everyone Else Practices Martial Arts

Started of great but went downhill from chapter 250+. He forgot he killed poseidon and others, he got stagnant with his power so there was no more growth and from 250 till 500 its all just provoke retaliate provoke retaliate.. it goes on and on. The story seems meaningless and with no growth of the MC it became very boring. Even the interactions between the MC and the others seem ridiculously stupid. A powerful 19 to 20 year old man with, according to the novel, had a powerful mental strength but had nothing in mind other than to fight and kill without thinking about the consequences. He makes enemies like he is breathing with no thought of what would happen to Annie. Such a great disappointment.
