Kao Ni La! Zhanshen Xitong

An Lin is a student in debt because of his father. While being sued by creditors, he accidentally falls off a roof. Fortunately, he is narrowly saved by a god. Touched by the sad life of the young man, the god offers him a system allowing him to have powers and convinces him to join the university of the kingdom of the gods in order to learn to practice martial arts and become immortal one day. Nevertheless, An Lin soon realizes that the latter tricked him and gave him a poisoned gift. (Source: Nautiljon, translated)
