Not bad, but the fact that Mc is so OP and has trillion year worth of knowledge except the author is an inconsistent ... doesn't help. Like, bruh, the usage of mana stones is just bad, using superior stones on things that shouldn't exist at Mc current stage/location. Why the hell does a town/city have a staff that is op. When the background of the city makes it seem like it is pretty weak. Is this city supposed to be like that stupid op village trope that all Chinese game novel has. There are other plot holes, so many of them. Honestly sad, but it makes sense. Mc may be op, but the author is for sure not op nor smart enough to write such a plot.
