Drunkenly Slaying Through the Ages

Chen Sanjin is the young master of a coffin shop. He has three great loves in life: drinking, dodging creditors, and arguing with a limping old yellow dog. He wears a rusty iron-bladed knife at his waist, and everyone in town laughs at him, saying it couldn't cut tofu.

Then, on a stormy night, seven assassins trampled the old yellow dog's bad leg. No one saw how Chen drew his knife. They only saw a cold, desolate arc appear beneath the moonlight. As the old yellow dog died, it transformed into a sky full of golden light, and Chen Sanjin finally understood: the dog had guarded him for eighteen years, protecting the secret of the ferocious blade left behind thirty years ago by a sword immortal from Shu. The rusted knife shed its first layer of rust, and from that moment on, the jianghu knew no peace.

One coffin, one jug of strong liquor, one rusty blade. He's come to collect what the jianghu owes him.
