Zhang Ronghua's expression remained unchanged as he thought to himself, The wine was tampered with?
With their relationship, the Crown Prince had no reason to do this.
Moreover…
His external medical and alchemy skills had already reached the sixth realm of skill. Even if the Crown Prince had a strong foundation, he would not be able to hide it if he wanted to do something.
Once the truth was revealed, the two sides would completely fall out. With his current power, if he were to stand on his own or support a prince to govern the country and secretly control him as a puppet, coupled with his terrifying ability, even if the three dukes, the empress, the crown prince, and the imperial family all joined forces, they would not be able to resist.
It was impossible for the Crown Prince to not see such a simple question.
Out of caution, he was about to use his Spiritual Eyes to check if the wine had been tampered with.
