Ghost energy has resurged, and vengeful spirits run rampant. Lin Mo's innate talent allows him to contract with only half a ghost, but he unexpectedly awakens a Defense-Breaking System. As long as he breaks a ghost's psychological defenses, he can forcibly contract with it. While others enter ghost domains to survive, he enters them to collect ghosts. Starting with a crippled ghost and eventually commanding ten thousand spirits, Lin Mo grows stronger through wave after wave of ghost attacks, gradually discovering his close connection to the fallen Kingdom of Demon Sealing. When the Ghost King leads an army to attack, he discovers that his subordinates have already become Lin Mo's contracted ghosts. Facing an even greater crisis, Lin Mo decides to lead his army of ten thousand ghosts to reclaim their homeland and protect the human world.
