A City with Gravity Reversed

[Suspenseful science fiction × urban adventure × deep thinking] Five years ago, an accident caused gravity to reverse, and two parallel worlds unexpectedly merged. The inverted world is on top and the normal world is on the bottom. The passage connects the two worlds, in which matter and living things circulate. Lin Yi is an ordinary cross-world courier, and his daily job is to deliver letters between the two worlds. He thought his life would continue to be so ordinary until—— The passage begins to disappear. The first channel disappears, the second channel disappears... When the last channel disappears, the two worlds will be completely separated, and all life will be destroyed. In order to prevent the disaster, Lin Yi embarked on an investigative journey. He met the mysterious Su Qing, a woman who seemed to know the truth about the passage; he met the crazy scientist Chen Yu, a fanatic who would sacrifice everything for research; and he discovered Shen Yifei, an ambitious conspirator who intended to control the passage. As the investigation deepens, the truth gradually emerges: the passage is not naturally formed, but a system created by a higher-level existence-the "Creator". The core code controls the operation of the channel, and this code is modifying itself, threatening the survival of both worlds. Facing the choice—— Let the two worlds merge forever? Is it to completely close the channel and separate the two worlds? Is it the power to modify the core code and control the channel? Or should we leave the choice to everyone and let the people decide their own destiny? Lin Yi once thought he was a chess piece of fate, but later discovered that he could be a chess player.
