Before the trip to the Southern Wilderness, Meng Qi decided to bring the Supreme-wisdom Tree that had engulfed a single layer of the Immortal Realm including Three-life Temple, considering that it had an integral relationship with the issue of reincarnation. He hoped that clues could be found based on its reactions and it did come in handy in critical moments!
The branches and green leaves of Supreme-wisdom Tree swayed, allowing the vague feeling around the Supreme Deity Mirror to spread like water waves, touching itself.
Even though Blood Sea Rakshasa did not know the Supreme-wisdom Tree and its functions, Meng Qi's acts made him uncomfortable. Both his realm and his experience as a Dharmakaya master tell him that he must not let the tree touch the Supreme Deity Mirror, or his years of efforts would reduce to nothing.
