Back when we first occupied Qingzhou, Chen Xi initiated a round of iron smelting. Although Chen Xi didn't know much about iron smelting, he did understand high temperatures and hydraulic casting.
Besides, the Lub Central Iron Mine is one of the few in China with reserves exceeding a billion tons. Even though Chen Xi didn't know the exact location, he just drew an approximate area and asked people to search for it.
In the past, Chen Xi even made a batch of high-quality refined iron weapons to impress Liu Bei, but they ended up being cut down by Liu Bei's standard weapons, dealing quite a blow to him.
However, this didn't shake Chen Xi's enthusiasm. After all, the small steel plant was already built, and abandoning it would be a waste of resources. So, Chen Xi put great effort into researching nurturing techniques.
