Fantasy: This System Is a Bit Skinny

Jiang Xu travels to a parallel world and is a high school senior. How can he survive in this high-tech world with the "Leather" system? Where do the strange beasts wandering in the no-man's land outside the city come from? Where do those deliberately hidden space cracks lead to? At this moment, there are less than two months left before the martial arts college entrance examination... … "Donor, whose mosquito net did you steal and wear on your legs?" "Are the two flowers blooming?" "That lunatic is here again, and his words can make people angry to death!" "This familiar BGM... Is that madman Jiang Xu!" … … Jiang Xu doesn't need to work hard to practice, he can become stronger with just a "skin". The thoughts in my mind came out involuntarily. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
