"Good! Daoist Lu, this way!"
Mu Yuanshan led the way in front, while Lu Xuan and Zhang Jingxian entered an area shrouded by a Sky-Reaching Giant Tree.
Only when they reached its base could they truly feel the astonishing appearance of the Ten Thousand Year Spirit Wood.
The trunk was unknown how many zhang in diameter, with branches of varying lengths spreading out and piling together like a small mountain. The surroundings were filled with incomparably dense and pure vitality.
Only, at present, its condition did not look very good. Countless Gray Spots of all sizes marked the massive trunk, each Gray Spot exuding an aura of deathly stillness.
"Daoist Lu, please wait a moment."
Zhang Jingxian stopped, and Mu Yuanshan at the very front took out several Emerald Green Array Flags. With a casual wave, the array flags silently merged into the restriction beneath the Spirit Wood.
"In addition to the two Nascent Soul Fellow Disciples guarding the grotto-heaven, a powerful restriction has also been arranged beneath every divine tree. Ordinary Nascent Soul True Lords cannot break through them."
Lin Jiangyuan at the side transmitted his voice to Lu Xuan.
After a dozen breaths, layer upon layer of emerald-green curtains rippled up beneath the Spirit Wood, and a gate of light that only allowed one person through appeared before everyone.
Everyone filed in one after another.
After entering, Lu Xuan flew up and stopped before a Gray Spot roughly a zhang square.
"Daoist Mu, when exactly did these Gray Spots appear?"
He softly asked Mu Yuanshan, who had also flown up.
"The larger the area, the longer it has been there. The biggest one has existed for nearly two years already."
Mu Yuanshan knew every change on the Ten Thousand Year Spirit Wood like the back of his hand
