My Supermarket Connects to Ten Thousand Worlds, and I Make My Family Eat Their Words Without Regret

After seeing his grandfather off on his final journey, Lin Bei, who has terminal cancer, returns to the little supermarket his grandfather left him. By chance, he becomes the owner of the Myriad Worlds Exchange and the lord of myriad worlds.

His first customer is an empress from the Great Liang Dynasty, a world much like his own. He trades her food for a jade pendant. After closing the deal, he thinks he can spend his remaining days in peace, but then the Lin family's fake young master shows up and nearly infuriates him to death.

Fortunately, the empress arrives. She quickly brings her imperial physician to examine him, but the physician has no cure and can only extend his life by two years.

To better help the empress, and to bring greater benefits to his country before he dies, Lin Bei chooses to work with the state.

However, he has no idea that trading with customers from other worlds is gradually healing his body through the Myriad Worlds Exchange.

With time running out, he also makes contact with a zombie world. But an accident lands him in the hospital, where he nearly dies.

Just then, a disheveled old man with a white beard arrives at the Myriad Worlds Exchange. After learning who Lin Bei is, he shoves a pill into his mouth.

Lin Bei is cured. An investigation reveals that the person who tried to kill him was Lin Yiman, the Lin family's second young lady, who lives in the little supermarket.

When the old man with the white beard meets Lin Yiman, he discovers that she has been afflicted with a mind-control gu. Only then does Lin Bei realize that both he and the Lin family have been targeted...
