The protagonist Lin Yuan was originally a promising scholar. He was falsely accused and imprisoned for breaking a conspiracy between powerful officials and a cult, and was exiled to the black mist wasteland known as the "Living Forbidden Zone". In this desperate place where wronged souls are everywhere and demons are rampant, Lin Yuan, who is dying, accidentally obtains the golden finger of [necromancy], which allows him to see, communicate with and subdue ghosts. The first "soldier" he conquered was the ghost of the most ferocious "Headless General" in the wilderness.
Since then, Lin Yuan has embarked on a completely different path. He used necromancy to establish his own "ghost kingdom" in the wasteland, integrating prisoners, ferocious beasts, and ghosts, and his strength expanded rapidly. He discovered that the so-called Black Mist Wasteland was actually a huge seal that suppressed ancient evil spirits. The powerful officials who framed him back then were the leaders of the cult who tried to destroy the seal and release the evil spirits to overthrow the dynasty.
Lin Yuan led his undead army, like a vengeful army returning from hell, fighting out of the wasteland and returning to the world. He investigates secretly, using ghosts to infiltrate the capital and collect evidence; he uses thunderous means to send his former enemies to hell one by one; he and the heroine, who represents the righteous power of the court, go from hostility to cooperation to jointly fight against the evil cult forces. Finally, under the capital, Lin Yuan summoned 100,000 Yin soldiers to engage in a decisive battle with the demon army of the cult. He shattered the enemy's conspiracy in one fell swoop and revealed his terrifying power as the "Lord of Ghosts" to the world. He became a living legend that even the emperor was afraid of.
