Zhang Caixin acknowledged Elder Yu's guess, but she had no intention of saying more. She merely stated that their cultivation was "not limited to" Thunder Talismans.
Yet even this limited admission gave the others quite a shock, along with... limitless room for speculation.
After a moment of silence, Elder Yu spoke again, gesturing with both hands. "Your cultivation can produce those... talismans that summon thunder out of thin air?"
Zhang Caixin first glanced at Feng Jun. Seeing no reaction from him, she shook her head. "Talismans are talismans. They can't be equated with cultivation. But at the very least, you need to cultivate before you can activate a talisman."
Elder Yu nodded slowly. After a while, he asked, "So even if someone else obtains one of your talismans, they still can't use it if they haven't cultivated?"
The question sounded somewhat ill-intentioned, but he asked it anyway. Zhang Caixin's answer was equally straightforward—she did not even need to look at Feng Jun's expression. "That's right. Without cultivated spiritual energy, holding a talisman is useless."
The words "spiritual energy" carried some risk of revealing too much, but Elder Yu had heard of far too many so-called masters. What was spiritual energy? Quite a few masters even called it "immortal energy."
What concerned him more was this. "Can't the talisman really be activated by other means? Lasers, electromagnetic fields, things like that. In the end, it's only a form of energy conversion, perhaps an energy field... Is there something wrong with my understanding?"
Zhang Caixin truly could not answer that question, because she genuinely did not know whether technology could replicate spiritual energy. She was inclined to believe it could not, but she could not give a definite answer.
So she could only turn to Feng Jun with a pleading look.
