After considering the situation, he said to himself, "How did they manage it, though? What kind of power is it? Is every divine transformation cultivator capable of such a thing, or only the best of them are capable of it?"
"And this is only the power of a divine transformation cultivator. What kind of power will they have after they are done transforming into the divine? Will I ever have the chance to experience such a profound power?"
He asked himself many questions beyond this. He is an innately curious person, so his questions were endless. The fact that he had so many questions on his mind also caused him to be frustrated because he didn't have a good way to find answers to them.
He can find the answers to his questions by asking the spirit of the tower. He can also ask the spirit of the tower to sell a cultivation technique to him or even ask it to create a new one for him.
So the information he wants is readily available. But the information is not cheap.
