Wen Feng, an ordinary young man who failed miserably in his business and was heavily in debt, was at the most desperate low point in his life. He was pretended to be comforted and deliberately deceived by his trusted "friend". After being knocked unconscious, he was sealed alive in a thick sarcophagus and buried deep underground, with the intention of letting him die silently in desperate circumstances.
In the sealed sarcophagus, the oxygen was quickly exhausted, suffocation and despair devoured his consciousness, and death was approaching step by step. Just when he was dying, he was accidentally bound to the interdimensional golden finger - [Chat Group of All Heavens and Worlds], and his nickname was automatically locked by the system as the King in the Coffin. His extreme desire to survive made him put down all his dignity and sent a desperate plea for help in a chat group filled with all the big guys: "The king in the coffin at the beginning, waiting online, urgent!"
The masters of immortality, magic, technology, and fantasy from all over the world regard this underground desperate situation as a novel cross-dimensional live broadcast, and they all rush to help. Someone gave him a wisp of ghostly fire that can penetrate all things, someone taught him the secret technique of turtle breath that does not require mouth and nose breathing, and a technology boss even directly shared the complete blueprint of a micro-material decomposer.
Relying on these seemingly random cross-dimensional rewards, Wen Feng used his last strength to break open the sarcophagus buried deep in the ground and climbed out of the ground with difficulty. But what greeted him was not rebirth and redemption, but deeper despair.
This is no longer the modern world he is familiar with. The sky is blocked by the never-ending gray fog, and the sun cannot be seen; the prosperous city has been reduced to ruins, and countless indescribable shadows are wandering in the ruins; human civilization has completely collapsed, and the survivors can only huddle in sporadic safe zones to survive.
