Yu Kaiping wasn't foolish, he immediately realized that Qi Dingjiang's reaction was somewhat strange.
Speaking of which, the illness his son, Yu Chenglong, had contracted was very mysterious in itself; he had consulted numerous Divine Doctors, yet none could give a clear explanation.
Only Qi Dingjiang, who had barely examined him, quickly determined his son's condition and was able to stabilize it every time.
Moreover, when he inquired about him, it turned out that Qi Dingjiang had never shown any medical skills in the first half of his life, yet he alone could treat his son's illness.
Wasn't that very strange?
Yu Kaiping had people investigate for several years, but they found nothing suspicious.
Later, as his son's illness recurred, only Qi Dingjiang proved able to stabilize it, so he had no choice but to rely on Qi Dingjiang.
Now, suddenly hearing Zhou Yu raise doubts, the suspicions buried in his heart surged forth again.
