Fengshadu: Landmark Festival's Millennium Agreement

Yun Xiao, a descendant of the guardian of the Jiangnan Earth Line, strayed into the time and space hub "Wind Sand Crossing" while inspecting the ruins of the ancient Silk Road. He accidentally awakened Zhang Qian's soul projection and was entrusted to fulfill the "Millennium Contract" - gathering time and space artifacts and the souls of cultural envoys of past generations to resist the entropy demon and extraterritorial evil demons who attempt to destroy traces of cross-civilizations. He gathered partners such as the earth line guardian Lei Yan, the soul ferryman Yue Li, and the Tiangong successor Mo Chen, and joined hands with cross-civilization practitioners such as the Japanese student Fujiwara Yuki and the Arab international student Islan Yue to participate in the three major cultivation trials of the Landmark Festival, the Humanities Festival, and the Tiangong Festival on Yuanxu Island. After going through numerous tests such as earth line tracing, civilization interpretation, and artifact repair, he gradually grew into a "Heaven and Earth Contract Master" through the grading and title sealing ceremony. In the process, everyone awakened the souls of ten cultural envoys including Xuanzang, Zheng He, and Matteo Ricci, worked together across civilizations to crack the conspiracy of the "One-Pulse Evil God," and launched the ultimate showdown with the three demon kings at the hub of the black hole. In the end, Yunxiao integrated the power of the three major systems of earth veins, cultural veins, and weapon skills, activated the "symbiosis barrier", sealed the evil spirits, reshaped the rules of Yuanxu Island, and made Fengsha Crossing an eternal hub for cross-civilization exchanges. The team of international students brought the concept of "symbiosis of heaven and earth" back to the present world, and the inheritors continued their mission of guardianship, composing a thousand-year epic of the blending of civilizations and the symbiosis of heaven and earth.
