Chang'an Galaxy

In the seventeenth year of Zhenyuan, a "white night" vision appeared in Chang'an. Sitiantai Li Yun pressed the copper button of his grandfather's relic, and the wall slid open to reveal a metal corridor. The official seal was heated and read: "Identity verification passed. Countdown: 100 days." He and his general supervisor, the female Prime Minister Chi Yan - a woman with a different blood who can control gold - discovered a shocking secret: Thirty-eight years ago, an alien scientific research ship crashed in the Qinling Mountains, and its technology was disguised as an armillary sphere, Feng Shui dragon veins and hexagrams from the "Book of Changes" and buried underground in Chang'an. Now the mothership has returned to start the "civilization assessment". If the Tang Dynasty cannot prove its independent wisdom, the entire civilization will be sealed and taken away. Before the countdown reaches zero, the leyline nodes extract life energy in reverse. Yu Chiyan uses his body to delay the disintegration of the lock, while Li Yun uses the evaluation process to witness the true power of human civilization: the ultimate ingenuity of farmers, the will of doctors to seek truth, and the weeping humanity described by poets. In the end, the universe left a verdict: "The experiment passed. Characteristics: blooming in bondage. Waiting for you to enter the sea of ​​​​stars." The alien stars left, and there was a self-propelled star track beside the Chang'an Armillary Sphere. A gentle watch star hung forever in the night sky - that was the first independent answer submitted by mankind to the galaxy.
