Delivery boy Wang Lei (Famous King Lightning of the Yuan Dynasty) travels through Dadu in the Yuan Dynasty with his body and an incubator. Relying on the "miraculous" preservation of the insulator to make milk tea and white sugar, he founded "Khan Bali Speedy", dealt with Kublai Khan, the treacherous minister Ahema, and the emperor's master Pasiba, and was even awarded the title of "Queen's Food Delivery Messenger". The incubator is actually a quantum device for the "interstellar express" of higher civilizations. It was annihilated by using up energy to send Wang Lei home.
Wang Lei, who woke up in modern times, discovered that the Yuan Dynasty experience was true, but was hunted down by the mysterious organization "Entropy Shadow". The fragments of the incubator reveal its true nature: a container for the ignition of civilization. He was forced to take over as the "Earth Webmaster" to repair the historical cracks tampered with by Entropy Shadow, but he fell into a closed loop of cause and effect - the kangaroo pattern on the blue and white porcelain of the Yuan Dynasty, the water-suppressing beast of the Yellow River, and the blood edict of Kublai Khan were all interrelated with his intertwined actions of ancient and modern times.
In order to end the heat death crisis, Wang Lei led the Multi-civilization Alliance (Silicon Tribe, Dinosaur Logistics, Tar Civilization) to send the twin universes into the singularity to restart the Big Bang. In the end, he turned into a cosmic rider, using an incubator as a boat to deliver the fire of civilization forever. The aroma of milk tea becomes the first taste of the new universe.
