Now that he had made a decision, Wang Wei needed to think how to approach her. He could try to hide in the Source Qi Space and send a projection, but since he can navigate that thing, he did not think that a Half-Step Transcendence could not do the same.
'Should I use the plan I have for Supreme Unity? No, this plan requires a lot of preparation, and I need more information to determine whether it can even succeed,' Wang Wei thought. In the end, he decided to take the risk. The power difference was too vast, and his cultivation was weak, limiting much of his options. So, he must take the risk and enter the lion's den.
As for how he will meet Maitreya? The answer was simple: he only needed to find a Buddhist Temple and say her name. Wang Wei did not believe for a second these two did not have ways to contact or influence the world during their fight; that's why he stayed away from Taoism and left them as the last piece to dispose of.
