Du Shi Qing was going to treat the Iron Cloud Nation's emperor's sickness while Tie Shi Cheng was going through his most difficult time.
"Senior Du, not only did you save my father's life, you even offered treatment free of charge to we poor peasants. Furthermore, you even gave us a tael of silver before you left! My family is greatly indebted to your kindness!"
When the young man saw that Du Shi Qing still trying to recall the event, his eyes lit up and he grew even more excited. "My parents were not very well off back then. The future of our family was grim. Our lives depended entirely on the tael of silver you gave us. Senior Du, your kindness is greater than the Heaven and Earth. You are our saviour!"
