As much as how a lot of people complain about the “summary” after reading it a bit the plot isn’t that bad. To be honest, it’s not much different than the other Japanese post apocalyptic plot where there is a safe haven city with a magical academy. Still, there are other Chinese comics out there that have a low quality plot, at least this one has a more decent one.
Also, the translation is obviously MTL. Not just in the summary but also in the comics. I can understand as to why the rating is low. Still, plot is 8/10 while the translation 3/10.
