"I hope so," Lin Ziyin replied with a subtle smile, "As long as their silver turns into mine, I don't mind."

"Forty percent, it's pure profit." Lin Ziyin answered with a faint smile, "Of course, the materials cost money; it's not like I'm asking for your iron for free."

A slight smirk tugged at the corners of Chu Suifeng's mouth, fortunately, he had several iron mines.
