Coiling Dragon's "Mental Energy=Spiritual Energy"

The old man smiled and nodded. “Linley, you must know that when most people die, their spirits will enter the Nether Realm! But because I was a Saint-level Grand Magus at the time of my death, my mental energy had obtained physical form. That was the only reason why I could temporarily resist the call of the Nether Realm and seal myself within the Coiling Dragon Ring. Right now, there is only one way for me to leave this ring – exhaust all of my remaining mental energy.”

“Exhaust all your remaining mental energy?” Linley didn’t quite understand.

“What men called mental energy, ghosts might call ‘spiritual energy’. When a person’s mental energy was utterly exhausted, his soul would naturally dissipate. In other words…when my soul dissipates, it will leave the confines of this Coiling Dragon Ring.” The old man said calmly. “But the current situation is fine also. Although I am confined by the Coiling Dragon Ring, preventing me from ranging more than three meters away from it, this isn’t too bad.”

Unlike in the past, Linley had now soulbound the ring with his own blood, giving him a deeper level of understanding.

“Linley, no need to speak aloud. Just speak to me mentally. As the master of the Coiling Dragon Ring, you can directly engage in spiritual communication with me, as I am a spirit within the ring.” Doehring Cowart’s voice rang out in Linley’s mind.

“Grandpa Doehring, why didn’t Uncle Hiri see you just then?” Linley mentally asked Doehring Cowart.

“Linley, I must inform you that aside from you, nobody can see me. Because right now, I’m just a spiritual projection, which has no matter. I’m invisible to the eye. Only you, as the master of the Coiling Dragon Ring, can see me.” Doehring Cowart explained in detail.

“There’s still some people who can sense my presence. Those whose spiritual presence are on par with me can feel my presence. But naturally…if I hide within the Coiling Dragon Ring, they definitely won’t be able to sense me.” Doehring Cowart’s voice sounded within Linley’s head.

“On the same spiritual level as Grandpa Doehring?” Linley chewed and thought at Doehring Cowart at the same time.

“Those who have the same spiritual power as me are most likely Saint-level combatants. Only Saint-level combatants can sense my presence, if barely. But of course, the prerequisite is that I appear outside the Coiling Dragon Ring. Once I enter the ring, there is no way they can find me.” Doehring Cowart smiled as he spoke.
