Through the conversation with Golden Boy, Han Fei roughly confirmed the strength of Golden Boy. He should be the fake king of the human race. His words "If I die, the Immortal City will be finished" were enough to show his identity.
As for Golden Boy, he had already confirmed that Han Fei was on the path of becoming a king. Han Fei didn't know how he figured it out.
However, Golden Boy was right. Since he became an Explorer, he had been actually walking on the path of becoming a king, especially after he returned to the Yin-Yang World.
Besides, there was another reason: the human beings had struggled for too long in the cage. Now, they needed someone to break it!
Han Fei's appearance did give Golden Boy hope.
The strong had their own resolve. For example, Golden Boy knew that the dragon bones were good, but he still gave them to Han Fei.
Han Fei nodded and asked, "Between you and the Black Evil Conch King, who is stronger?"
