Although the elder of the Ning family owed Xiao Chen a favor, Xiao Chen had not set out specifically to save him and had paid him no attention throughout the ordeal.
Even when Yan Zun threatened him with the life of the Ning elder, Xiao Chen had said he did not care about the man's life or death, and still moved against Yan Zun, with Lei Ao ultimately saving the elder in the end.
So, to strictly categorize this as a life-saving grace, Xiao Chen would indeed feel ashamed to accept such acknowledgment.
Furthermore, he had previously pledged a promise of a fair exchange, and now that he had received what was due, he would not renege on what he owed the Ning family.
After all, it was merely a trivial effort on his part.
"Mr. Xiao, do you truly have a method to cure the Cold Syndrome?" the Ning elder asked in astonishment.
"Of course!" Xiao Chen's indifferent tone was full of certainty.
