the mc said he wanted to keep a low profile and improve, but one thing is for sure he's done everything but that!

Same pattern as 99.99% invincible MC type novel, but here in worse, full of clichés and above all the MC already has a ridiculous cheat, added to that a ridiculous past, and you end up with a shitty novel.

the mission where the MC with his team kills Pakura makes no sense from start to finish except for the MC, otherwise the others received a spy mission to find out the reasons for the tension, and not to kill people especially high-ranking Suna who are allies, certainly an unreliable ally, but an unreliable ally is better than one more enemy for a weakened Konoha.

The basic premise of the novel is really tempting, but you quickly realize that it's just a bait to attract readers, nothing more. The worst part of this novel is that the author doesn't even bother to explain why certain things happen, why they happen so quickly, or why they're possible. It's not that the author doesn't want to reveal the secrets too early, but simply offering some hypotheses or answers from ordinary characters would have helped to better understand what's going on and why it's happening. Additionally, it would have made it easier to accept potential explanations later, as the information would come from non-experts. But no, the author prefers not to explain or justify anything, creating a world without rules, which is quite disappointing.

The beginning was very well written, but the moment the Heavenly Dao list appears, the novel is ruined. The author then starts an over-escalation of cultivation levels, and the progression becomes too fast. One thing I particularly hate is that the protagonist steals the power of the Heavenly Dao without suffering any consequences and begins to replace it. To me, the Heavenly Dao represents a set of immutable rules. So, either the protagonist becomes the Heavenly Dao himself, making him a sort of emotionless arbiter (which could be interesting), or he should not be able to devour it, because doing so would mean being assimilated by it. Yet, he gets the best of both worlds, which seems incoherent and illogical to me.
