Gray fog enveloped the world, and the apocalypse was coming. Chen Mo was hit by the "Doomsday Supply and Marketing Cooperative" system, and he was saddled with a staggering debt of one trillion system coins at the beginning. The system mall has unlimited supplies, but every purchase makes the debt snowball get bigger and bigger - if you can't pay it off, you will pay with your life.
In an abandoned apartment, he rescued Su Qingxue who was seriously injured. She was once a special forces instructor and a botanist who dreamed of turning the desert into an oasis. However, the apocalypse destroyed all the green she protected. Chen Mo handed her a bottle of water and a first aid kit, asking her to guard the store for him. From then on, Su Qingxue became the number one bodyguard of the convenience store. She was decisive and aggressive externally, but internally she was a hidden foodie who could be bribed with a pack of snacks.
Starting from exchanging a pack of instant noodles for a crystal core, Chen Mo built a safe zone, set up a black market, recruited franchisees, and used tactical missiles to kill extraordinary beasts. When Adam, the leader of the "Utopia", bought people's hearts with free supplies, he played the truth card and disintegrated the collectivist utopia maintained by emotional control. Going deep into the hinterland of the gray fog, he discovered that the end of the world was not a natural disaster, but the colonial transformation of the alien civilization Kanos. In order to save his brother Wang Lei, he spent all his money in exchange for the "Water of Life"; to fulfill Su Qingxue's dream, he planted the World Tree that can purify gray fog.
In front of the portal, Su Qingxue detonated the space collapse bomb and used the power of the World Tree to protect her last breath. Chen Mo found her in the ruins and said: Go home
On the day the debt was paid off, he became the first Earthling to counterattack from a debt host to a dimension general agent. Under the World Tree, he knelt down on one knee and took out the ring polished by himself with the first piece of metal in the apocalypse. She said yes
In the new world, his convenience store is still open, but there is no IOU anymore.
