A Heng, a cultivator with useless spiritual roots, accidentally obtained the mysterious "Unknown Sword Art" and an ancient sword in the dark jungle, but was involved in the shocking conspiracy of the Netherworld force "Netherworld Terrace". In order to protect the common people, he went deep into the Jedi with his sword, and with the help of the elders of the Qinglan Sect, he found out the truth - the ancient seal "Eye of the New Moon" was on the verge of collapse. Faced with powerful enemies and world-destroying disasters, he chose the most decisive retrograde path with only the fifth level of Qi refining. He combined his body with his sword and his soul as a contract to cast his will into the eternal seal and forever suppress the rift in the netherworld. Going against heaven does not mean betraying the Tao, even a dead spirit can keep one's heart. A bloody legend that began in humble beginnings and ended in sacrifice was lost in time, leaving only the echo of the sword.
