In the 17th year of the Republic of China, Sun Dianying exploded the Eastern Tomb of the Qing Dynasty. The night pearl in Cixi's coffin suddenly lit up, and strange blood lines suddenly appeared on the body - this was a sign that the ancient secret treasure "Netherworld Iron Coupon" appeared in the world. Legend has it that this coupon is divided into two parts, Yin and Yang. When combined, it can open the "Tomb of the Immortal". The person who gets it can control life and death and control the Yin soldiers. Zhang Jiuye, the former commander of the Qingshen Machine Battalion, was hunted for his involvement in the Dongling robbery. After hiding his name, he formed an alliance with Ye Hongzhuang, the descendant of Xiangxi exorcist craftsman, and Zhao Shouyi, an abandoned disciple of Huangpu. They searched for the whereabouts of the iron coupons in the ghost market of Peking, the royal tombs of Yinxu, and the Sanxingdui ruins.
At the same time, Japan's "Oriental Culture Research Institute" Colonel Inujiro led a team to rob ancient tombs in North China in an attempt to resurrect the Kwantung Army's undead army with iron coupons; warlord Sun Dianying did anything to survive, and the mysterious Feng Shui master "Ghost Teller" controlled the corpse to commit murders. All forces set off a bloody storm in the troubled times. The hallucination puzzle caused by the bronze sacred tree, the ghost wall curse on the hanging soul ladder, the secrets of exorcism in the zombie village in western Hunan... Every time the protagonist group breaks an ancient tomb, they reveal a bloody past about immortality.
When the iron coupons are about to be unified, the "Tomb of the Immortal" under the Tianchi in Changbai Mountain appears, and the ancient evil god "Zhu Jiuyin" breaks out of the coffin. The undead soldiers who used it collided head-on with the Japanese biochemical troops in the Battle of Western Hunan. Zhang Jiuye broke into the tomb with the sword of the Kwantung Army, Ye Hongzhuang used the corpse exorcism technique to ward off millions of ghosts, and Zhao Shouyi carried a bag of explosives and stepped onto the soul-hanging ladder. In the era of warlord rule and Japanese invaders, they were not only rogues looking for gold, but also lonely warriors guarding the mountains and rivers in the gap between the underworld and the human world.
