In almost every fanfiction where there is a system, the mentally retarded author wants to cram in an old dinosaur shit about how the protagonist insults the system and its injustices. He doesn't even value what he's been given.
Another one to read and forget. The potential was lost from the first chapters, and the protagonist does almost nothing in a couple of "battles" that are not interestingly written.
As usual, he says one thing and does another once he gets into the everyday world, he says that Japanese girls are worse than Chinese girls. Then the question is why did you get to know girls in this everyday world knowing that they are Japanese or in other worlds girls who are the same Japanese. And as usual, in a roundabout way, Chinese garbage in the form of techniques, weapons, etc...
