Yi Xiaochuan has lived for two thousand years. He was once Meng Yi, once a Jin Yiwei, and now he is just a specially appointed expert. His descendant Meng Yu is a heroic policewoman and amateur archeology live broadcast blogger. During a live broadcast exploring the ruins of the Qin Dynasty, Meng Yu was trapped and experts were helpless. Yi Xiaochuan appeared in the live broadcast room and gave casual instructions: "Turn three steps to the left. That is the birthplace of the crossbow mechanism. The craftsman back then was my buddy."
The entire internet ridiculed him, but Meng Yu did as he was told and miraculously survived! Later, Yi Xiaochuan casually threw a pulp-coated bead string (disguised as a tiger charm) to Meng Yu to ensure his safety, but was recognized by a transnational predator who knew the goods as the Great Qin Tiger Talisman that had disappeared for thousands of years, causing a global shock.
