"City Lord, are you keeping Xie Rui alive because you want to exchange for more resources?" Chu Yun was a little puzzled. Based on Su Ying's actions in the past, Xie Rui's bones would have been chewed clean by the wild beasts by now.
What Su Ying wanted was not just that bit of resources.
"There's an iron-smelting technique in the Jin State which can make the best use of the mined iron ores." Although the Chu State also had iron-smelting skills, their know-how was still inferior to the Jin State's.
During this period, she had repeatedly made requests to Xie Rui's henchmen to test their bottom line. She wanted to know how far these people would go to save Xie Rui.
Thus, before that, Xie Rui had to stay alive.
If the guard was acting on someone's order, it meant that there was someone with ulterior motives hiding near her.
