The Secret Key of Heaven

"Tiangong's Secret Key" - a guardian epic under the corrosion of time and space The "bronze sacred tree" of quantum entanglement connects three spaces in time: Late Ming Dynasty (1644): Chen Xiaodao, an ingenious young man, turned his right arm into bronze, lit up the Bronze Bird Tower, used machine skills to fight against the Qing army's mechanical soldiers, and fell in love with the singer Su Mingyue. Modern (2023): Chen Mo, the restorer of the Forbidden City, discovered quantum formulas in cultural relics, integrating technology and ancient martial arts. His daughter actually used mathematics to solve the Shang Dynasty code. Ancient times (Yin and Shang Dynasty): The shaman Zhu Chen Zhuo cast Jiuding Town in the turbulent flow of time and space, facing the first coming alien civilization. The three of them came into contact with the "Tiangong Key", an alien relic, and became restorers of time and space. The price was cruel "memory rust" - a loved one would be forgotten randomly every time they were repaired. A collision across time and space: The three lines of memories are interconnected, but they all experience the heartbreaking pain of losing their "father". Su Mingyue volunteered to be erased from history in order to protect the anchor of time and space. The modern daughter discovers that her father is an "antique-turned-spirit" and still gives him a warm embrace. The "quantum dialogue" between Mozi and alien civilization is shockingly unearthed. Final decision: When the third-tier civilization breaks through the dimensions, the protagonists say goodbye in their respective time and space (sword burial in the late Ming Dynasty, modern photos, and ancient bones). The bronze sacred tree blossoms, and they turn into the basic particles that maintain time and space. Only the birthday card of the modern daughter on the treetop is left, shining with the glimmer of immortal family love in the quantum foam. "The best time-space story is one that allows readers to see their own reflections in quantum foam." - A space-time symphony that uses bronze as its veins, quantum as its bones, and family love as its soul, exploring memory, protection, and the essence of civilization.
