Feng Tingyin, a sweeping odd-job worker of the Heavenly Sound Sect, is actually an ancient supreme being experiencing mortal life, comprehending the way of Taisu without sound. The deacon Wei Gaoao bullies everyone relying on a magical treasure, and is elegantly slapped in the face by him using an old bristled brush with silent power. The young disciple Yinyin is enlightened and advances through his guidance. Facing the invasion of the Sound Demon Sect, the Taixu Sound Hall, and even the ancient arch-enemy Mieyin Zunzhe, Feng Tingyin resolves the catastrophe with the greatest sound being formless, passes down the soundless great Dao, and interprets the true meaning that heaven and earth are all musical scores through his sweeping practice.
