Chu Yun selected a total of 20 core technical staff.
When everyone saw Su Ying, they stepped forward to pay their respects.
Su Ying didn't allow them to rise immediately.
"I have summoned all of you here today because I have something very important to tell you."
Those people looked at each other, wondering what Su Ying was going to tell them.
Su Ying instructed the Green Guardian to carry the iron smelting technique in.
"I know that all of you are good at iron smelting, but you can't raise the iron you produce to a level of excellence by yourself. Therefore, I found an even more powerful iron-smelting technique for you to refer to and learn."
