Lin Wu The Senior's Plan?

When Wang Xiong had heard Lin Wu's plan, he had thought that it was not something that could be possible. It was so absurd, according to all he had learned till now, that he had a hard time believing it.

But he finally did believe it because it was his senior speaking it. He had personally seen the Taiji Celestials tomb and the murals in it. He had also taken part in the trials and knew to make something like that would be incredibly difficult if not impossible for anyone in this world.

Not to mention the Cultivation inheritance that he had received, which was the biggest proof. 

With all these things combined, Wang Xiong just realized that his scope of understanding of this world was much less and he should just do as Lin Wu was instructing him to do.

It was Lin Wu's plan for him to use the communicating jade slip and break it. The jade slip had a part of Lin Wu's power contained in it, which Lin Wu had secretly added without telling Wang Xiong.
