Such a formation, was so remarkable that Lu Yan had never heard of any force possessing it. If word of it got out, other forces would discover that Zuo Yun had this capability, they would surely find a way to abduct him.
Therefore, it needed to be kept secret for now.
The location, quickly selected, was an area in the center of Lingdong City. The official statement was that it would be a new series of practice rooms, specifically for the elite forces to cultivate, just like in the Hidden Dragon Camp of the Mansion of King Ming.
Zuo Yun clearly stated that with his current cultivation level, the range of this array was only five hundred meters.
Anyone cultivating within this range would speed up their refining of Martial Food and Martial Pills.
Once his cultivation level improved in the future, the range of the array would inevitably increase.
Five hundred meters, was already more than enough, allowing many people to cultivate within.
