As soon as Chen Fan left the plantation, he went straight back to the Yin Dragon Pond.
It would take a normal person about two to three days to get to the pond from the foothill; however, it took the three of them less than four hours to complete the journey. As soon as Chen Fan was back, he cast a huge Mist Array and concealed the pond from the people following him.
He copied the Mountain Defensive Array that he used at the Yun Wu Mountain to the Yin Dragon Pond.
Fortunately, he had abundant Yin Crystals at the pond and with the Jade stones that he had acquired from members of the Yin Ghost Sect, he had enough material to construct seven consecutive arrays over seven peaks of the mountain. The seven arrays then formed a larger array that centered around the Yin Dragon Pond.
On the day that the Array was finally completed, not only were Master Wu and A'Xiu astonished by the feat, but also the members of the Yin Ghost Sect.
