This is a possibly reasonably interesting story despite the over used 'useless son-in-law is really the world's most powerful individual' but it is ruined by truly execrable translation wrt names and genders. I didn't notice grammar errors but with the distraction of the name and gender errors I wouldn't even if they exist.

They seem to have very advanced simulation technology since it can accurately simulate a language they don't know. The Normese woman in the simulation spoke it well enough that she could invoke what sounded like a sacred spell of self destruction as well as allow his skill to replicate it and learn it at level one, even when their systems and personnel don't understand it at all.

"More than 30" left with Wang Dalin and "18 other people" are left with Xiao Lin and Gu Xiaoyue, so where are the rest? An earlier chapter stated that all 60 classmates were present, so unless the author has a strange way of saying 40, some people are missing.

Yet in the previous chapter at least one of the spectators expected the initial fireball to reduce him to ashes, so this is not consistent.
