"Well... how should I put it? You can understand it that way for now. It's convenient." Sister Mengmeng changed the subject. "Let's talk about something interesting. Tell me—what do you think happens when immortals fight?"
"Of course it'd be earth-shattering, heaven-destroying, plucking stars and grasping the moon, blasting planets into celestial bodies—no, wait. Maybe they'd be completely detached from the mortal world and impossible for ordinary people to observe at all." Shi Tiexin scratched his head. "I really can't imagine it."
Sister Mengmeng nodded. "Unless they do it deliberately, ordinary people truly cannot observe battles between immortals. Mortals can only capture a faint residual trace."
Shi Tiexin asked curiously, "What kind of residual trace?"
Sister Mengmeng spread her hands. "There are plenty. Let's start with the most obvious one. The energy released when immortals clash falls from Absolute Spacetime into normal spacetime. During that descent, normal spacetime absorbs the energy and creates matter in order to maintain stability. Thus, elements of every color burst forth from The Void."
"Under the effects of ultra-high energy levels, most elements cannot remain on their own."
"Only elements with exceptionally stable atomic structures, electronic structures, and chemical properties can endure."
"Guess which element it is."
Shi Tiexin's mental arts immediately listed numerous possibilities, then eliminated them one by one through simulations. In the end, he reached an almost unique answer. "Gold?"
"That's right. Gold." Sister Mengmeng recited, "It can turn the sky full of flying white jade, and make the great earth into gold. This is the residual trace left by immortals in battle—the Immortal Golden Seal."
"If you ever see an Immortal Golden Seal, get the hell out of there immediately. Start with a hundred thousand kilometers. Run as far as you possibly can."
Shi Tiexin gave a bitter smile. "A hundred thousand
