When Bai Xuan, an immortal, was going through a tribulation and dying in the human world, a beggar who was about to starve to death gave him the only steamed bun in his hand. After Bai Xuan ascended to heaven, he found that this man had an incomplete destiny and was destined to be poor and lonely for the rest of his life. In order to repay the kindness of the beggar with a steamed bun, he tried his best to find a person with an extra destiny in the world, named Lin Xi. He forcibly stripped Lin Xi of his fate, causing Lin Xi to go crazy and kill his wife and son with his own hands. However, the fate that was forcibly stripped away could not fill the missing fate of the beggar, but it created an entanglement in fate between Lin Xi and the beggar that they could no longer get rid of. Bai Xuan was also punished by jumping off the reincarnation platform for secretly tampering with the fate of mortals.
The fate of the three people was entangled and completely changed because of a steamed bun.
