Chapter 478: Portal Management Bureau

After Liu Wenbo left, Chen Mobai began reading the Full Volume of Guiyuan Secret Technique that Luo Yixuan had sent over.

There was no difference in the first two layers, but on the most critical third layer, there finally came a detailed Cultivation Method.

"So, it's using Void Stones!"

After reading it, Chen Mobai couldn't help but be slightly surprised.

According to his understanding, the difficulty of the third layer was how to create a small external world without the aid of a Portal, a Supreme Treasure that could open up the Void. The method used by the Guiyuan Sect was to extract the Power of Void from within the Void Stones.

This was something inconceivable to the Immortal Gates.

The Void Dark Stone Vein on Di Yuan Star had already run out. Each remaining piece was treasured by the Immortal Gate, and even Nascent Soul Superiors had to apply for permission if they wanted to use it for research purposes.
