In the apocalypse of acid rain, human society has been brutally divided into five classes.
Scholars, breeders, warriors, operators, and mud people: these are both occupational categories and rankings of social status.
Everyone spends their life striving to enter the Babel Tower and become a scholar.
Lan Xi worked hard for most of her life, but in the end, her parents forced her to give the slot she'd earned to her younger brother.
After losing her slot, she was expelled and reduced to a mud person. In the end, she died miserably in the acid rain outside the safety tower, her body reduced to bones.
Reborn into a new life, Lan Xi decides she will never again let others take credit for her work.
She voluntarily gives up her identity as an operator and chooses to become the lowest-ranking mud person.
Mud people are those excluded from the base system. They are denied equal human rights and dignity, yet are still expected to shoulder the dirtiest and most degrading duties that keep society running.
Everyone despises her and thinks she's gone mad. Only Lan Xi knows she has awakened a secondhand trading System.
Even the acid rain that everyone else avoids can be turned from trash into treasure in her eyes.

Exchange! Exchange! Exchange it all!

In the apocalypse, biological toxins are everywhere, and there is very little food safe to eat.
To get one clean, safe meal, mud people often work for ten days and nights without rest.
Yet someone has opened an all-you-can-eat restaurant at the foot of a mine, in the most polluted place of all.
Food and water are unlimited. Apart from not wasting or taking anything away, there are no restrictions.
At first, everyone scoffs, convinced it must be a corporate conspiracy, tricking survivors into unknowingly joining inhumane human experiments.
But when people with nowhere left to turn enter the restaurant, prepared to die, they are astonished to find that the food is delicious and tempting, and eating it causes no discomfort at all.
What's more, after eating there repeatedly, the toxins that had built up in their bodies over many years gradually disappear.
Overnight, the restaurant is packed, with not a seat to spare.
Lan Xi makes a fortune. At last, she also has the means to teach those who bullied her a lesson they deserve.
Her buffet restaurant keeps expanding, and her reputation transcends the class system. Before long, the powers at the top of the tower take notice of her.
Scholars, breeders, warriors, operators, and mud people: this system may seem reasonable and keep society running, but the lofty corporations are watching hungrily, the shadowy players in control are luring people step by step, and there are sobs in the acid-rain mist, and strange, shifting ghosts in the darkness...
