It was highly possible that those ripples were coming from the Hellion Aether Flower!
That's why Tyrion had seized the opportunity to escape the grey-cloaked Elder by diving into the magma lake. This way, he could spend his time searching for the Hellion Aether Flower, instead.
"That old fart. The next time we meet, I'll give you a taste of my moves." Tyrion coldly snorted to himself. If there hadn't been other things holding him back, how could he have let himself be suppressed like that? If Tyrion had gone all out, then that old fart would either be dead, or have had a layer of his skin scraped off. However, the exchange would've been exhausting on Tyrion's part.
Tyrion didn't slow his search as these thoughts circulated through his heart. The deeper he dived into the magma lake, the stronger the heat became. The temperature at this depth was even starting to penetrate the defenses of his Hellfire Blackflame.
