"Have all three of these crops been found?"
Li Xuan became excited in an instant, "This is the spell message from two days ago, they should have arrived in Tongzhou by now, right? Have them come to the capital as quickly as possible, and bring the items to my mansion for me to see."
Yu Hongchang, however, looked at him puzzled, "They're just some foreign items, not some kind of immortal grass or miraculous treasures. Xuan, do you really need to be so excited about this?"
Li Xuan replied with a smile, "What if the yield per mu for these potatoes and sweet potatoes could reach three to five thousand jin? What if this corn could increase the yield per mu of the northern lands by three to five stones? Moreover, these potatoes and corn can also serve as staple food, right?"
In the world Li Xuan came from, potatoes were introduced to Middle Earth by sea merchants during the mid-Qing Dynasty.
This was a high-yield crop that could easily produce one to two thousand jin per mu.
