"The memory scene mentioned the four great treasure trees. Could it be that a treasure tree exists within Violet Spirit Heaven?"
Mu Qing stroked his chin in thought.
In truth, Mu Qing had already investigated most of the clues regarding the four great treasure trees.
First, he had already obtained both the Thunder Treasure Tree and the Reincarnation Treasure Tree, with both ancient secret arts firmly in his grasp.
The third ancient secret art was the Sealing Secret Art. The Sealing Treasure Tree had once been controlled by the Lord of Jade Mystery Heaven, but later, that mysterious powerhouse had broken in and seized the Lord of Jade Mystery Heaven's True Meaning of Sealing.
However, Xuan Qing's guardian body, transformed into a stone statue, should still possess the True Meaning of Sealing. Once he grew strong enough in the future, he could find a way to seize it.
As for the final ancient secret art, Mu Qing currently had two guesses.
His first guess was that the mysterious powerhouse who had killed the Lord of Jade Mystery Heaven possessed the fourth ancient secret art and was gathering the remaining ones.
However, it could not be said with certainty that the mysterious powerhouse possessed the fourth ancient secret art.
After all, the matter of the four great treasure trees could be learned through all manner of surviving clues, which meant that the four great treasure trees had not been much of a secret at the time.
That Jade Mystery Heaven possessed one of the treasure trees, the Sealing Treasure Tree, was most likely known to the majority of people as well.
It was also possible that the mysterious powerhouse did not possess the fourth ancient secret art at all, and had simply sought out and killed the Lord of Jade Mystery
