The Savior from the Well

Modern engineer Shen Feng travels through time to Heishicheng. He encounters matchmaking and chooses two weakest 'burdens' that no one dares to take. The crowd laughs, but Shen Feng uses limestone, cement, iron, and steel to build city walls. While others fight for rice, he leverages Silk Road trade with glass mirrors and steel blades, building an industrial city in this barren land.
