Su Qing's expression turned serious when she took it over. Xiaoying, watching her sister from the side, also became nervous.
"Sister, What is this?"
Su Qing studied the stone closely. The weathered surface was grayish-black, and iron oxide could be seen. The fresh surface was dark green, uneven like a human brain.
"Iron ore."
Su Qing wasn't sure, so she asked Xiao Qi to check it out and concluded that it was iron ore.
"Iron ore? What's that?"
It was Xiaoying's first time hearing this term, and she was very curious.
"Let me see."
Ji Shuisheng had just finished teaching Zhong Yong martial arts and walked over to ask Su Qing if there was enough firewood to use. When he heard their conversation, Ji Shuisheng was instantly interested.
"Here."
Su Qing passed the iron ore to him. Ji Shuisheng looked at it carefully and said to Su Qing,
"I'll go to Yongkang to take a look."
"Alright," she said.
