Feng Zhongxiao and Zhu Meiyan respond to their orders. Li Si wandered around the city wall, and suddenly saw his iron-blooded mercenaries wearing a piece of diamond armor. He couldn't help but feel a sudden move in his heart. Yes, since he can make alchemy equipment, why can't he use alchemy on the defense of the city wall?
