Zuo Lu returned to his own room and sat cross-legged on the ground. He spoke to his mind's sea, "Master Deng, I've arrived in my room. I checked, and it appears no one nearby has noticed anything amiss here."
"Mm," Master Deng said, "Bring me paper and pen."
Deng then saw Master Deng controlling Zuo Lu's body as the Primordial Spirit's power was activated, and swiftly writing something on the white paper.
Zuo Lu realized that the content was all in secret code, which was indecipherable unless one knew how to interpret the hidden language.
It seemed that Master Deng knew his thoughts and said with a smile, "This is my understanding of the first to ninth levels of the Great Black Flame Fire Dragon Formation."
Seemingly in good spirits, Master Deng continued to write and added a few more words: "Do you know why I, as one of the thirty-six true Lords of the Combat Division and a proper Heavenly God, am still interested in the Taoist Skill of mortals?"
