The Sixth Sage: I Am Yuxu's Junior Brother

Modern teenagers brought the system to counterattack the ancient times and became a disciple of Yuxu. Carrying the holy body of Dao Yun, he obtained the Daluo cultivation level at the beginning, but he hid his skills for a hundred years, hiding behind the twelve golden immortals in the disguise of a heavenly immortal. When the Tribulation of the Gods arose, he used the system to foresee the flaws in all methods, beheaded the Ten Heavenly Lords in front of the Ten Jue Formation, defeated Sanxiao in the Yellow River Formation, and used the wisdom of a mortal to break through the Jie Jiao Killing Bureau. Joining forces with the saints in the Immortal-Zhuan Formation, they sweep through the immortals in the Ten Thousand Immortals Formation, and finally become a saint with immeasurable merits and virtues, becoming the sixth heavenly saint in the ancient world, taking charge of the way of humanity and redefining the world. When a time traveler who is familiar with the script of the Conferred Gods develops the Heaven-defying System in a low-key manner, the fate of the entire prehistoric era will be rewritten because of him.
