Primordial Era: Starting with a sign-in reward of the Sun Star

Lin Yun transmigrated to the primordial world, becoming Lu Ya, the tenth son of the Demon Emperor Jun. Born with a god-level sign-in system, he received rewards for each sign-in. Signing in at the Sun Star yielded the top-grade innate spiritual treasure, the [Fire Source Pearl]; signing in at Buzhou Mountain, the Great Dao-level cultivation technique, the [Hongmeng Dao Scripture]; signing in at Zixiao Palace, the Chaos spiritual treasure, the [Twenty-Four Grade Chaos Purple-Gold Lotus]. The sign-in spree was endlessly enjoyable, and Lin Yun continued his journey of continuous sign-ins. When the Lich War erupted and the Twelve Ancestral Witches stormed the Demon Court, Lin Yun had already achieved the Great Luo Golden Immortal of the Primordial Chaos, wielding the supreme Chaos treasure. He annihilated Pangu's true form with a single palm strike and single-handedly fought against the saints. "The Demon Court reigns supreme above the Heavenly Dao, destined to be the eternal protagonist!"
