The Crown Prince's last words were worth pondering. From what he said, he didn't have many friends and their cultivation was high. The only person who could get the Heaven's Will Saint Soul Fruit from the Netherworld Ancient Insect was Yang Hongling.
A new doubt appeared. Why didn't he use the power of the Empress or the palace? The former was his mother, and the latter was his father. If it was really useful for his hidden illness, they would have to come forward.
There was only one possibility. The Crown Prince was hiding something and didn't want them to know.
Thinking of this…
Zhang Ronghua overturned his previous guess in the palace. It was true that the Crown Prince's vitality was damaged, but it was not left behind when he was young. What was hidden inside? He had a feeling that if he could figure this out, he would be able to unravel the mystery and obtain what he wanted.
