First of all, this novel is in a category of Light Novel, so there is not much of an expectation from me.
I seriously enjoyed the story early on. It's an underdog story, about a kid who is fated to be nothing much, that even his father decide to keep him away so that he won't be a trouble when the war started. And by his own power (more or less...) he rise above that expectation and even more.
The MC himself is clearly portrayed as a kindhearted, highly motivated and dedicated martial artist, as well as treasuring (to a level of abnormality...) his family and friends. Or at least at first he was like that.
As the story drag on, the writer transform the MC into a manipulative egocentric lying assassin that would do ANYTHING to get what he wanted without ANY consideration to other people outside his circle. Seriously, he became a classic power hungry antagonist. This guy would insert himself to a group disguising himself as an ally and waiting for the right moment to stab someone in the back, seriously most of the story is like this. The concept of honor is alien to this guy (or this writer).
And the level of naivety of this MC (or writer) is humongous. I'm confuse most of the time, at one point the writer paint the world as a strong eat weak environment, like when the MC and his bird first came to underwater world, they would attack, enslave and consume any being that they wanted. But when the same thing is happening to the MC, he would act like it's some kind of heavenly injustice, what is he? an 8th grader?
Somebody killed his first master, and cut his father and uncle arm, of course he was angry that he wanted to kill the perpetrator, but no, he need to go further, he need to kill all thousand of people that happen to be near him, and also exterminate that guy school to the root. And when some people from teng long continent fight and unintentionally kill many of his relative and thousands of other innocent people, what did he do? He scheme and pit these two super power against each other that ultimately killed millions of innocent lives.
And by the way, the guy is not talented nor is he exceptional in any way (even his first master said so), his main feature is his luck, it's only because of his luck that he got that meteor tear (which alongside uncle Lan serve as deus ex machina a lot of time in this story) which allow him to reach peak houtian external master, it's only by luck that he managed to become the successor of stellar art, it's only by luck that he met with uncle Lan (and only god knows why the hell would this uncle Lan favored this guy so much) whose also give him that immortal puppet which the MC abuse its usage to the max (even though uncle Lan himself warn him not to).
In conclusion, this story would do well to be some kind of preparation for future story where Qin Yu is actually the main antagonist evil lord who is trying to control the universe
