Chronicles of a Quantum Warrior

Zhang Xiao, a quantum physicist, is accidentally swept into a rift in space-time by a resonance signal from the 'Xuanming' quantum computer during an experiment, and transmigrates to the Qingli era of the Northern Song Dynasty. He meets Li Juan, a skilled swordswoman; Fang Yuan, a guardian who has protected a seal for a hundred years; and Wei Chong, whose obsession once warped history.

Deep in the Qinling Mountains lies a mysterious device called the 'Heavenly Mechanism Lock,' imbued with ancient quantum entanglement energy. Using modern quantum physics as his key and the spirit of chivalry as his foundation, Zhang Xiao joins forces with the others to avert a crisis that could overturn the timeline. They seal the Heavenly Mechanism Lock, then hide the knowledge and power spanning a thousand years in the mountains, written on bamboo slips for future generations to discover.

Nearly a year in the Northern Song changes his understanding of the quantum world: science is not merely equations, but a way of existing alongside the universe. After returning, he writes this extraordinary tale as a book titled Records of a Quantum Swordsman, dedicating it to those whose names have faded with time, yet who never ceased to protect others.
