The number one killer in the world, codenamed Zero.
Twenty-seven-year-old Zhou Jin possesses purple pupils, spatial powers and a cold weapon, the Zichen Gun. However, at his peak, he got tired of killing and returned to the old streets in the north to open a small restaurant called "Tingxue Tower".
No one knew that this boss, who was extremely handsome and whose cooking was so delicious that it could make people forget their hatred, once made the entire underground world fearful.
Until gangsters come to collect protection fees, international killers come to seek revenge, and hostile forces sit in the same box, Tingxue Tower has an additional rule that no one dares to violate:
No one is allowed to kill anyone within Tingxue.
From a small restaurant with eight tables to the Tingxue International Hotel that has taken the world by storm, Zhou Jin no longer acts as a knife in other people's hands, but lets everyone who holds a knife sit at his table.
And his most hidden identity is that of the last emperor of the Zhou Dynasty.
