Sidaozhenguixu: There Is a Ruins in My Body

The four ancient ancestors joined forces to seal "Guixu" and left a prophecy: The day when the nine swords are reunited, the nine formations appear together, and the nine thoughts return to the origin, it is the day when the ruins are destroyed and the heavens are overthrown. Yun Tianyan is the only person in the prophecy who can carry the four inheritances at the same time. Sword Dao, Battle Body Dao, Formation Dao, and Divine Thought Dao—the four paths of Gui Yuan can suppress Guixu. He has fought all the way from the lone son of the exterminated clan to the ninth level. He has gathered the nine swords, realized the nine formations, and understood the nine thoughts. Everyone thought he would be the savior. Until he broke through the realm of creation, a dark will was born in the small world inside his body. That thing looked exactly like him. It called itself "Xu" and its first words were: "This world sucks, I'm here to help you destroy it." The Savior and the Destroyer live in the same body. The fate of the Nine Realms hangs in the heart of one person.
