How to evolve a dantian into a small world?
When Ye Xiao started to ponder over this matter, he became exceedingly confused. Since he could not understand how he can evolve his dantian into a small world so he asked the Celestial Poison Imperial Dragon about it.
The Celestial Poison Imperial Dragon replied, "Before trying to evolve your dantian into a world, you should merge with me. At that time, you will come to know on your own what to do in order to evolve your dantian!"
Although Ye Xiao wanted to know the answer right now, since the Celestial Poison Imperial Dragon told him to merge with him and he will know, he decided not to ask anymore.

After Zhao Yufei and Zhao Qing'er consolidated their foundation, Ye Xiao once again gave each of them one Water Spirit Herb and told them to continue cultivating.
