Zhang Mingde, a 70-year-old retired man from Shanghai, accidentally gets bound to the "Myriad Realms Heavenly Screen Livestream System," but mistakes it for rogue software. He goes about his usual routine: scanning QR codes while shopping for groceries, cooking meals and watching TV dramas, taking his granddaughter to and from school, and riding the subway for medical checkups. Little does he know that his ordinary retirement is being livestreamed in real time to people from the Qin, Han, Tang, Song, Ming, and other dynasties. A smartphone, a meal of braised pork, a short drama, and a routine medical examination are enough to shatter the understanding of people across countless dynasties, sending emperors and ministers into a frenzy of research, reflection, and reform. Discoveries such as the Haihunhou Tomb, the Mawangdui Tombs, and the Oriental Pearl Tower further spark collisions between civilizations and deep feelings of national pride. Completely unaware of what is happening, the protagonist uses the simple, everyday warmth of ordinary life to shake the very fabric of time across the ages.
