The Gunman of Yanlong

The overworked office drone Zhao Liangyang had just finished an all-nighter when some mysterious big shot set their sights on him and summoned him to another world. Other people transmigrate into human bodies, become the protagonist, and save the world. I can only possess a gun and provide support. Forced to follow the protagonist on a path of revenge in this world.

The whole main plot is basically me lying around.

Brother Lu, come on in. There were too many people outside just now, so I'll get down on my knees for you here.
