We Are Each Other's Coordinates in the Realm

When Lin Qingxuan opened his eyes, he had landed in a strange "dungeon world". The first level is "704 Abandoned Building" - ghosts dragging knives are peeping in the dark, there are weird tasks on each floor, and there is also the taboo of "Don't look back, don't let the count reach seven". He pushed through, only to realize that this was just the beginning. After leaving 704, he was involved in different dungeons such as deserted villages and old hospitals. There were strange rules hidden in each place, and every step was a test of life and death. The more I pass through, the clues I pick up gradually come together: old documents are mentioned as "screening", survivors talk about the "Old Testament", and even the ghosts in the copy seem to have similar resentments. He vaguely felt that these copies were not isolated. He and other people involved might be tied to the "truth" behind them. He must continue to break through, find the root cause of all the copies in series, and figure out why he was dragged into this cycle.
