When the jade pendant experiment of Li Yang, a doctor of quantum physics, caused a space-time vortex, he was forced to travel to Handan in the late Warring States Period. In a ruined temple on a rainy night, he rescued Ying Zheng, a young man with a royal seal engraved on his wrist, but found that the jade pendant he was carrying actually contained the DNA of the future emperor.
From making a compass to decipher Zhao Jun's conspiracy, to using magnesium powder to forge heavenly punishment to frighten the Yin and Yang family; from improving Qin Nu to create a three-stage attack tactic, to discovering the alien starship murals in the Lishan underground palace - Li Yang had to use the technology tree of the 22nd century to carve out a path of survival in the bronze civilization. However, the lemon juice secret message on the bamboo slips of "Han Feizi", the Baiyue quantum totem at the bottom of Yunmengze, and the illusion of burning books and entrapping Confucianism that flashed when he coughed up blood all hint that this time travel is no accident.
When the cracks in the jade pendant produce quantum resonance with the Jiuding star map, when Ying Zheng's blood detects extraterrestrial metal elements, and when the figure of the modern archaeological team appears in the holographic projection of the ashes of burning books - Li Yang finally realizes that he is both a tamperer of history and the 7294th experimental subject of the Interstellar Civilization Observation Project.
This is a civilizational leap spanning three thousand years:
Use a magnetic levitation chariot to crush the cavalry of the Six Nations, use a blockchain ledger to reconstruct the Qin economy, and start a quantum computer under the Epang Palace.
When the electromagnetic pulse tears apart the dimensions of time and space, Li Yang, who is holding the jade pendant tightly, must choose - to let Ying Zheng become the 001 observer of the Interstellar Federation, or to protect the most primitive civilization fire of mankind in closed-loop space and time?
