Oh yeah, I did not play this game in Chinese; however, there is someone taking screenshots of the game to share, and I noticed there is a translation error
It's where Unum wants to have a "hybrid" with the MC, so "hybrid" is not "混血儿"， since "混血儿" means mixed of different human race. So, for a slightly accurate vocab will be "混杂种".
Just wanted to point this out, however it is a very great game!
