Although the Jianmu Divine Needle includes the character "wood," it is not actually a true tree.
It is more like a super-giant structure made of top-tier Wood Dao Spiritual Materials, and thus the inside of the Jianmu Divine Needle is not solid but has a different kind of space.
For example, the internal space Su Yuan is now entering.
After stepping through the wooden door, there is still another door ahead of Su Yuan, one resembling a bank vault door.
Although it's unclear what material this door is made of, it is certain that any power below Nascent Soul cannot budge it in the slightest.
Behind the door lies Su Yuan's intended destination, the Storage Chambers of the Power of Celestial Spirits and Earthly Fiends within the Jianmu Divine Needle.
According to the instructor, there are a total of one hundred and eight storage chambers inside the Jianmu Divine Needle.
Different numbered storage chambers vary in their reserves of the Power of Celestial Spirits and Earthly Fiends.
