If you meet one and a half Meng Xin, it probably means that you can run the map by yourself, but you can't run the whole map, and you don't know the position of the light wing. Then it's been a while since you finished. You know something, but you don't. You only know a little, and then you die and have corresponding clothes, but you still don't have the skills. That's right, even if you are a half-Meng newcomer.
