I Became a God of War After Breaking a Bone?

Anzhi is a freshman who was born frail and sickly. He accidentally broke his leg during military training, so he took a temporary leave of absence to recuperate at home. In the first week after being discharged from the hospital, he was suddenly taken away by two strange elves with wings. They came to the top of an office building and started an inexplicable battle, and even won. Little did he know that the opponent he defeated turned out to be the son of the villain boss, the arrogant son of the Demon King Zhao Qingyu. The son of the Demon King who was just starting to fight against humans was instantly defeated. However, he did not cause trouble for Anzhi. Instead, he became Anzhi's follower and fought against monsters and humans together.
