After a moment.
In the highest building of Medicine King Valley.
"Master Wang, what is this!" Lu Qingshan looked at Wang Jin, then at Jiang Ning, showing an inquisitive expression.
Jiang Ning said: "My master was harmed by villains and is seriously injured, so I came here to seek medical treatment."
"No problem, since Commander Jiang has asked, I will surely do everything I can to heal him!" Lu Qingshan responded without hesitation.
Jiang Ning subtly observed Lu Qingshan's expression but still couldn't discern anything.
Then he once again cupped his hands and said: "Sect Master Lu, if you can heal my master back to his original state, I will owe you a favor!"
"Is that true?" Lu Qingshan suddenly looked at Jiang Ning seriously.
"It is true!" Jiang Ning nodded firmly.
"Good!" Lu Qingshan said: "With your word, no matter the cost, I will heal all hidden injuries on your master, leaving no aftereffects."
"Thank you very much!!" Jiang Ning cupped his hands in salute.
