The Twelfth Afterimage

2246. Human beings are suspended above the city and enter the "nether world" after death to continue living. No one knows that a woman named Pu Yan built twelve doors 186 years ago to hide the earth. The door started to leak. Living people will be embedded in the walls, and laughter will become viral. Jiang Su is the engineer responsible for fixing bugs, and Su Wangyan is the diver who can hear the voices of dead people. They thought they were repairing the cracks in the world—until they discovered that for every bug fixed, a door was pushed open. Outside the door, an ancient civilization that thinks "the earth is not beautiful" is approaching. Su Huanyan discovered that the twelfth door was in her body. She could walk in and close the door from the inside - at the cost of possibly never getting out. Science fiction × suspense × Chinese classical literature. Twenty-two chapters, 300,000 words, not a bad ending.
