In the early years of the Republic of China, German geologist Hans Kraus led a team into Wuxiang County, Shanxi Province in the name of mineral exploration, secretly searching for the legendary "Longhu Tomb" - a secret mausoleum that suppressed the ancient ferocious beast "Evil Dragon". The local warlord Marshal Zhao sent troops to assist, but he did not know that the real goal of the Germans was the dragon power in the tomb that could create "immortal soldiers".
Chen Qingyang, a descendant of General Faqiu, sensed the crisis and teamed up with the mysterious archaeologist Su Xiaowan (actually the successor of Mojin Xiaowei) to explore Long Lake at night and discovered that the Germans had used human blood sacrifice to awaken the evil dragon. There are many mechanisms in the tomb, the dragon-locking pillars burst, the evil spirit leaked out, and the German experimental subjects lost control and turned into bloodthirsty monsters. Chen Qingyang took the risk to activate the "Tomb Burning Array" to kill the dragon and destroy the tomb, but it caused the bottom of the lake to collapse and narrowly escaped death.
However, the disaster is not over yet. The remnants of the German army fled with the scales of the evil dragon and started fighting with the warlord Marshal Zhao in an attempt to resurrect the undead army. The evil spirit spreads and the people are infected with strange diseases. Chen Qingyang discovers from the ancestral dragon vein map: The evil dragon is just the beginning - there are still six "dragon evil places" in the country, and the Germans' next target is the "Yin Dragon" imprisoned for thousands of years under Mang Mountain...
In order to end the disaster, Chen Qingyang and Su Xiaowan rushed to Luoyang, went deep into the maze of ancient tombs, and faced the "living corpses" transformed by the Germans and the half-human, half-dragon monster leader. In the end, Su Xiaowan pierced the Yin Dragon's heart with the dragon-slaying sword inherited from her family, while Chen Qingyang detonated the dragon-burning array and died together with the overwhelming evil energy...
When the dragon evil wakes up, the mountains and rivers will overturn; if you touch the gold on a hill, you will suppress it with your life.
