'What is it that makes everyone want to get to the peak of the cultivation realm?'
[Host, the question you have asked has a pretty vague answer. Every cultivator has a motive. Just like how your motive is to annihilate God's Legion, all the cultivators would have a goal to achieve.]
[Some have their childhood sweetheart taken away, some want to get back to their family which abandoned them, some do it for revenge to destroy the supreme powers of the Multiverse, some do it just for universe domination.]
'What about after they achieve their goal? - scratch that - my main question is, What about me once I reach my goal? What if, by the luck of my last eighteen generations, I succeed in killing Wang Yao? What will I do after that? Won't I succeed in finishing my motive?'
'After all, Wang Yao is the only opponent who can stop me from getting to the Throne. Me killing him would also mean I will get the Throne. Once getting the Throne, what will be the motive?'
