A quartet of modern agricultural doctors traveled to an imaginary dynasty:
No vegetables? Impossible, high yield cucumbers can be grown without pollination
No staple food? Impossible, potatoes are being promoted as a staple food
Soil salinization, soil correction with organic fertilizers
An optimistic and half-baked doctor of agriculture traveled to Sichuan and North Korea. After a series of hardships and obstacles, he realized the true meaning of the agricultural major, which also led to the development of crop cultivation in the dynasty.
Mission: Stay optimistic and God will reward those who work hard
