In 2157 AD, Shen Yuanzhi, chief quantum architect of the Post-Era Civilization Reconstruction Bureau, was accidentally thrown into Luoyang City in 689 AD during a space-time resonance experiment. When he woke up, he found that he was penniless except for the quantum computing chip implanted in the cerebral cortex and the future technological knowledge base carried in the nanomemory.
Faced with the turmoil on the eve of the Wu Zhou Dynasty and the Tang Dynasty, Shen Yuan knew that directly throwing out technology that was beyond the times would only lead to death. He chose to start from the most basic level - using improved abacus and accounting methods to gain a foothold in Luoyang West Market, but unexpectedly attracted the attention of Xie Qingshang, the daughter of a merchant. Xie Qingshang was keenly aware that this young man of unknown origin possessed mathematical logic far beyond that of the current world, and the two formed an alliance.
