If it hadn't been for Su Chengyu bringing Gong Juechen, how could the poison in his body have been cleansed? How could his health have improved?
Su Chengjin was truly grateful to Su Chengyu.
However, Duke Tao didn't feel any gratitude at all, and even snorted, "You can know the face but not the heart. He seems to be good to you, but you must have also heard that having the doctor cure you has also made his reputation even better. His reputation was already good enough, and now it's even more so... He is really good at putting on a facade, something you could never compete with."
After a pause, Duke Tao added, "He's not only good at presenting a front but also excels in currying favor. Since your father favors Prince Yi, he just schemed his way in. Look at how he behaves toward Prince Yi, how lowly he places himself, but what's the purpose? It's nothing but to secure his position as the Crown Prince, to sit more firmly in that spot."
