"This Wood Spirit Tree Root is far too valuable. Lu feels unworthy to accept it. May I ask if there is anything I can help you with, Senior, or if I might exchange some other Treasures for it?"
Lu Xuan knew perfectly well that the Profound Limit Tree Mother would not gift him such a rare Treasure without reason, so he asked of his own accord.
"I merely wish to use this Treasure in exchange for a promise from you, Daoist Lu."
The Profound Limit Tree Mother spoke gently.

"The Tree Realm is located within the Azure Wood Star Cave. Though its geographical position can already be considered excellent, it still is not safe enough."
"If a great crisis befalls the Tree Realm in the future, I hope Daoist Lu will take this Wood Spirit Tree Root into consideration and lend us a hand."

Lu Xuan pondered for a moment, then told the truth.
"That is no problem.
