Yu Jingrong wanted nothing more than the Mining Mountain; the other two were just a ruse, a disguise to avoid arousing Su Luo's suspicion.
Su Xin was indeed not suspicious, and she was shocked by Yu Jingrong's words, truly taken aback.
From her dealings with Su Luo, Su Xin felt she understood Yu Jingrong - she didn't see her as a greedy woman. Yet now, here she was, demanding her business properties using Su Xin's daughter as a bargaining chip. If these were her own to give, there wouldn't be much of an issue offering something of little value for the sake of her daughter. But the fact was, they weren't hers at all – they all belonged to Li Fengnian.
If Li Fengnian found out she was using his properties to save Su Luo, he would certainly not spare her!
But in truth, even if the properties were hers, she wouldn't have easily parted with them. Yu Jingrong was despicable – it seemed she had also deceived her daughter, Luoluo.
