Huo Hai found it strange. This was the first time he had seen a hand seal accompanied by such a phenomenon. Then his heart grew cautious, because he knew that this signified a truly secret inherited spell.
The true power of spells was completely different from what Huo Hai usually used. Normally, he merely used spellcasting techniques to forcibly empower them with his own spirit energy. This was an extremely crude method. If Huo Hai's Spirit Insects had not been inherently powerful, then with ordinary spellcasting materials, the result might not even have been as powerful as attacking with his own hands.
True secret inherited spells, forged through countless refinements, usually came with all kinds of phenomena. This was because, when such spells were used, one's spirit energy resonated with some unknown law between heaven and earth, producing such manifestations.
Before reaching the Earth Grade, using these secret arts could faintly draw upon a trace of the Power of Heaven and Earth for reinforcement. This was one reason spells were far more powerful than a Battle Spirit Master's Battle Spirit Art. When Earth Grade experts used spells, the Power of Heaven and Earth they could communicate with could even far surpass their own strength. Back in the Divine Mystery Sect, Huo Hai had encountered a secret inherited spell once—the Frost Dragon.
Unfortunately, one had not been cultivated to mastery, while the other was purely for assistance, so neither had produced such a phenomenon. As the hand seals were released, the flames around Huo Hai suddenly began to gather in a bizarre fashion.
In but a moment, countless fine threads of flame appeared around Huo Hai. Coordinating with Red Sparrow's spell, these fiery threads continuously attacked his entire body from every direction. Even Huo Hai found such an assault extremely troublesome.
