read till chapter 100.
The other comments are from earlier in the manhua it seems,
Yeah there is a deeper reason why the MC is actually unaware that he's super powerful, no there is no 'system he got cause he transmigrated' there is an overarching plot and surprisingly its very clear by even chapter 60s that what's going on if you piece together the clues but by chapter 100 its pretty overt as to what actually is happening. other than that its mostly comedy and like half the time is just enjoying the art which is pretty damn good.

The plot resembles "Above ten thousand people" and "I'm really not the demon god's lackey" in which the MC has no idea that he is OP. Other people can instantly sense that he's OP and some immortal or whatever and that leads him to gain the respect of others who are clamoring over the benefits he brings them. It's supposed to be comedic and stuff but unlike the two that I've mentioned above, the storyline/plot just feels weak and lacking in entertainment. The whole "OMG you are so OP" in the previous two manhuas were used to explore the side characters, their motives and their personalities, but this this manhua, it is just used merely to show how OP the MC is. It's fine if it's used like this one or two times, but any more times than this is just pure boring.

Moreover, none of the side characters are even interesting. They exist just to be used as props to the MC and barely anything is even shown about them. What are they doing? What are their goals? What about the world building?? The only saving grace is the MC, where he is not some prick or typical manhua MC asshole that wants to dominate everyone else and randomly kills people. However, other than him and his sentient artifacts, the rest of the cast and the whole story is boring and lacks substance. Hopefully the author would try to add something new later on but as of now it is lacking.
