The residence wasn't too big, but an astounding amount of spiritual energy had gathered in the area. With just a glance, Zhang Xuan could tell that there was a Spirit Gathering Formation set up in the area. It was of a fairly high grade, grade-6 pinnacle at the minimum.
Due to the presence of the Spirit Gathering Formation, the spiritual energy in the residence was several times more concentrated than that outside. The entire courtyard was densely filled with rare medicinal herbs, those which one would hardly see on the market.
"Not bad!" Sweeping a glance at the surroundings, Zhang Xuan saw at least ten stalks of Saint herbs, and his eyes lit up in amazement.
Even You Xu didn't have that many saint herbs in his garden back then.
Jiya!
While Zhang Xuan was still looking around, the doors to one of the rooms opened, and a haggard-looking old man appeared. Looking at Zhang Xuan and the others, he bellowed, "Who let you all in? How brazen!"
Phew, not late by too long
