Celestial General went to find the Celestial Crystals. Li Xiandao gave him two paths. He couldn't choose to be a slave, so he could only think of ways to acquire Celestial Crystals so he could exchange them for lifespan from Li Xiandao.
"If I was in the celestial world, a million low-grade Celestial Crystals would be like nothing. I could acquire so many just like that and I could bankrupt the Bank of the Universe from exchanging all of them." Celestial General thought about it helplessly.
Unfortunately, this was the Nine Skies and Ten Lands, not the Celestial World.
He could only go to someplace to search for Celestial Crystals.
...
Within the Bank of the Universe, after the Celestial General left, no more guests arrived.
Li Xiandao cultivated in peace. He absorbed spiritual energy, stored them in his dantian, and then injected them into the worlds.
