After Bai Jingshan's death, his older brother Bai Jinghe returned to Kaoshantun under the identity of a patriotic overseas Chinese, investing in road construction openly while eyeing the Nine-Dragon Coffin at Laolongkou secretly. Li Changsheng protected Su Yu and Niuniu, leading the villagers into the mountain, where they dynamited a century-old Kaluga sturgeon out of the ice lake, and used wild boars, wolf packs, and bleeding-sorrow to deal with the mercenaries. Bai Jinghe's evil intent persisted; he forcibly built a scientific expedition highway, excavated the death gate, and released miasma and long-haired zombies. Li Changsheng broke into the sinkhole, seized the Taisui, and bombed the transport plane, cutting off his thoughts. Finally, Zhao Jianguo led troops to take over Laolongkou, and Deputy Director Wang was arrested, but Bai Jinghe's life or death remained unknown, with a whistleblower still watching from the shadows. Kaoshantun temporarily grew rich, but Li Changsheng knew this matter was not over.
