After the waiter Qin Zhi rescued the mysterious old man, he received a coin and became the new owner of "Yedu Bank". Lifespan, memory, emotion and soul are traded here. He quickly transformed with his trading ability, traveling around the city and trading with people - saving the rich in exchange for their loyalty, helping the miracle doctor but losing the memory of his beloved. As the transaction expanded, he was gradually involved in the conspiracy vortex of the black-robed men, "boundary keepers" and other forces, and faced side by side with Sun Wan, the eldest daughter of the Sun family. Everything has a price, but the true value is much more than meets the eye. Can Qin Zhi keep his true heart while controlling all things? What kind of secrets are hidden behind Yidu Bank?
