The Deliveryman at the Civilization Experimental Site Saves Humanity

Takeaway boy Chen Kezheng received a strange order - the "cemetery" at the foot of the mountain. Other takeaways were scared to abandon the order, but he bravely came to the door. Unexpectedly, he actually activated the ancient mathematics problem on the sarcophagus, and opened a portal by the way, throwing him and two archaeological graduate students - a liberal arts man who specializes in ancient writing, and a material girl who specializes in testing carbon 14 - into the mysterious ruins. In the ruins, the trio of Shennong, Nuwa, Fuxi, Huangdi, and Cangjie... Gradually revealed the truth during a thrilling adventure: aliens had played a civilized experimental field, and they, ordinary people, had become the key to the fate of the earth.
