Prehistoric: a Song Cuts Off the Soul, and I Prove the Hunyuan with the Suona

Traveling through the ancient world, Gu Changqing found that he had become a mutated spiritual bamboo rooted in the ancient battlefield of gods and demons, sucking endless evil energy. In order to suppress the evil spirit, he broke off the main body, put a piece of broken bronze on it, and made the king of musical instruments, suona! Coinciding with the sanctification of the Sanqing Dynasty, the gate of Yuxu Palace was opened. Gu Changqing was repulsed by the assessment formation because of his evil aura. He blew the suona in anger, shattering the illusion formation with a wild sound, and threw ideas to Yuanshi Tianzun. "The Sanskrit sound of the Great Dao teaches the gentleman, and the soul of the underworld restrains the villain. To explain the teaching, you need light, and you also need a ruler to measure the bottom line of the rules." These words went straight to the core of the teachings of Chanjiao, and Yuanshi Tianzun, who valued the most discipline, was greatly appreciated. He immediately made an exception and accepted him as his personal successor, and gave him the Dark Blade of Chanjiao that is independent of the Twelve Golden Immortals! Internally, if the Twelve Golden Immortals are arrogant or trapped in inner demons, he will forcibly cleanse their Taoist hearts with a voice of great joy, beating them to the point of shutting up and thinking about their mistakes. Externally, the big demon who dared to run wild in the Kunlun Mountains because of his deep heel was buried with a sad song, which directly destroyed his soul. The God-Measurement Tribulation has begun, murderous intent surges into the sky in front of the Ten Thousand Immortals Formation, and the immortals of the Chan Sect are locked in a bitter battle. Gu Changqing was dressed in neat Yuxu Taoist robes and strolled into the formation holding a black and green suona. The shrill sound of the suona resounded throughout the world, and hundreds of ghosts marched at night to summon endless Yin soldiers. The violent sound waves ignored all magical defenses and directly tore apart the peerless killing array, shocking the saints in the sky. Facing the Western Cult's attempt to take advantage of the Duhua Sanskrit, Gu Changqing played the most outrageous soul-breaking song, causing eight hundred disciples of the Western Cult to have their Qi and blood flow backwards on the spot, causing their Taoist hearts to collapse. A song of underworld crosses the gods and demons, a sigh of confusion over the years.
