Fang Zhou, I'm just a farmer, not Shennong!

After Lu Yuan came to this world called Terra, he awakened a system called [Shennong Cultivation].
However, the condition for activating this system is that Lu Yuan must complete professional studies related to agriculture and own a field of at least five acres in a designated area, and this designated area is Longmen!
After graduating from Tianshi Temple with excellent grades, Lu Yuan arrived in Longmen and initially purchased a five-acre piece of land, officially starting his farming journey.
Congratulations! You have successfully harvested rice, increased basic attributes, strengthened Originium skills, and gained the water attribute ability [Water Array Wall].... Unlocked a new crop [Proliferation Rice]
Congratulations! You have successfully harvested potatoes and gained the ability....Unlock a new crop [King Potatoes] One potato can meet the calories you need for a whole day.
Congratulations! You have successfully fed everyone in Longmen! Upgrade your land and gain abilities...
Later, Lu Yuan's former teacher Shu heard that Longmen had produced a Shennong who provided food for the entire Longmen and even the refugees in the surrounding countries.
When I arrived at Longmen with a learning attitude, I fell into deep thought when I looked at the rice fields that were as tall as a forest, the wheat that was like a golden ocean, the potatoes that were sparkling with orange light, and the various colorful crops.
