" Young Lord is right. Especially the farmers of the villages near the Nanhai Mountain. The solid soil and rocky terrain damage their tool often."
" Hmm, Interesting…" Jia Hao thought for a moment before looking at Old Yang.
" Old Yang, go and purchase some limestones. You know, those white rocks?"
" Ah, Yes…" Old Yang's expression turned odd, but he nodded. " I shall fetch someone to get them here."
" Meanwhile…" Jia Hao looked at Tong Yuan. " Prepare a big furnace, and cut a hole like this."
Jia Hao instantly drew a blast furnace and showed it to Tong Yuan. All the blacksmiths were curious when they saw that.
" Young Master, What's this?"
" This is a new method of smelting. It's called the blast furnace." Jia Hao replied. " With this, you can turn these rough and cracked iron into superior carbon steel."
" Carbon steel?"
The blacksmiths felt skeptical when they heard Jia Hao's method. However, looking at his enthusiasm, Tong Yuan nodded.
