God-Level Security Guard Jack Ma

A protagonist who imitates an urban mysterious sect keeper. Probably the protagonist is the best in the world and hides his identity. The element I plan to add is the Myriad Realm style. The protagonist hangs around in the city and develops special powers and becomes an immortal. There are many novels like this, so I will simply write about the protagonist who is a soldier in all the worlds, a son-in-law, a clan leader, etc. He is aloof and unknown. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
