Very good story. I almost didn't read this one because this type of story genre is usually focused on the Internet, computers and that section of high technology.
I am glad I changed my mind as this one is a very interesting novel to read.
Warning : as in most Chinese novels there's racism and nationalist propaganda and
this novel has an especially high level of xenophobia. For a novel about using a system, the author basically never refers to it after around 400 chapters all of a sudden the MC is now a genius instead
