Zhang Yan sat cross-legged on the rock, True Fire blazing within his Qi Sea, its brilliance akin to the noonday sun. He slowly moved the fire, guiding it toward an acupoint to burn through.
In just a moment, he felt the acupoint pulse as though breaking free from some constraint, like a sluice gate opening wide. A strand of yang energy, golden like silk threads, was cautiously drawn out by him and merged with the True Fire.
The True Fire, nourished by Essence Qi, now burned dazzlingly bright, illuminating the entire Qi Sea. Even with the added Star Fire-like speck, it seemed unchanged in appearance.
Zhang Yan gave it no further thought, focusing intently on the spell, turning the flames methodically but steadily. Not long after, his body trembled softly, and in that instant, another acupoint was burned through.
