In 2025, a mysterious game called "The Abyss" invades reality and plunges the world into a doomsday disaster. Dungeons randomly descend on the city. If you fail to clear the level, the whole area will be devastated.
Chen Ji, 23 years old, is a social loser who is terminally ill and fired from his company. On the first day of the "Abyss", he awakened his only F-level talent - [Death Echo: Can see the death countdown above the heads of all things].
Everyone laughed at him as the "worst observer", until they were struggling desperately in the high-risk dungeon, Chen Ji relied on predicting death to avoid all fatal traps step by step, and obtained the god-level reward hidden in the cracks of the world.
While they were still fighting on the first floor, Chen Ji had already reached the last floor.
"Your S-level talents are very strong, but only I can see how you will die in the next second."
