"The Balance of Tianmen" tells the extraordinary story of Chen Mo, a young archaeological team member. In the Mausoleum of the First Emperor of Qin, he accidentally touched the "Ancestral Dragon Card" and became a "sensor" who could resonate with historical figures, and met Qin Qing, an agent of the 749 Bureau. They discovered that due to the energy leakage of the "Tianmen", historical figures such as Zhu Yuanzhang, Li Shimin, Wu Zetian, and Wang Mang awakened in modern times as "Returners", but they were once regarded as threats.
When the returnees from ancient civilizations such as Rome intended to seize Tianmen and destroy the balance of global civilization, Chen Mo and Qin Qing resolutely joined forces with the Chinese returners to form a "Guardian Alliance." The four returnees each hold a key to the Tianmen and start a decisive battle in the Mausoleum of the First Emperor. In the end, Wang Mang's sacrifice and the belief of all members of the team to protect Tianmen activated Tianmen's "civilization barrier", repelled foreign enemies, and achieved preliminary peace.
After the war, the returnees integrated into modern life in their own way, nourishing the present with the warmth of history. However, the balance is not permanent. The newly discovered ruins in Kunlun Mountain, the puzzles of the "First Generation Trial", and the shadow of extraterritorial energy once again summoned Chen Mo and his partners to embark on a new journey. This is not only a battle to protect civilization across time and space, but also a profound exploration of history and reality, obsession and redemption, individual choice and the symbiosis of civilization.
