Ye Yan died one night at the age of twenty-three. His consciousness was extracted and permanently locked into a simulation terminal called "Hades".
There is no reincarnation here, only the endless deduction of murder cases. In the first hundred times of the cycle, all he faced were "ordinary" cases such as vendetta for unpaid wages at the bottom, sudden death from overwork at the middle level, and death due to domestic violence. There is no direct action by the chaebol, but there are fatal foreshadowings left by capital squeeze everywhere.
He was killed due to a mistake, cleared due to timeout, and collapsed because no one believed the truth. But every death is growth.
When he was finally able to restore all the truth from the clues and became the best reasoner in "Hades", the undisclosed cases related to the top chaebols that had never been made public had just exposed their fangs to him.
