Cheng Mo, a cultural relic restorer who suffered from brain cancer, was reborn in a parallel time and space as an ordinary high school student who had just completed the college entrance examination. Bound to the [Cultural Relics Returning Home] system, he discovered that every time he recovers a lost national treasure, he can exchange it for a piece of advanced technology. When he activated the quantum invisibility cloak under the Tower Bridge in London, when he hung upside down from the skylight of the Louvre to replace the "Yongle Dian", when he detonated a holographic smoke bomb in the Tokyo National Museum - there was a ghost codenamed "Blue and White Porcelain" in the files of the global spy organization. And as black technologies such as nano-mechas, quantum computers, and antimatter engines emerge one after another, the "three good students" who always smile shyly in the news are weaving a technological spider web that envelopes the world. ("I'm just an ordinary patriotic young man," Cheng Mo said, looking at the space-based weapons in satellite orbit)
