[Traditional fantasy + multiple heroines + no system + upgrade flow] Traveling through this world, Lin Yuan became a lowly slave of the Lin family. Until that day, the eldest lady kicked Lin Yuan seriously and knocked him unconscious. Little did she know that this blow was a blessing in disguise for him, allowing an ancient demonic empress to awaken from Lin Yuan's body! Since then, Lin Yuan has started a double life. During the day, he was still the eldest lady's house slave. Late at night, the arrogant eldest lady, possessed by the empress, took the initiative to push open his door again and again... From an ordinary slave to the master of all heavens, he controls the yin and yang of creation, breaks eternal taboos, and makes all living beings tremble wherever he passes! Until that day, Lin Yuan stood at the top of the era. The once unattainable Holy Land Fairy, the Godly Empress, and the eldest lady with a bad personality all bowed their eyebrows and surrendered at his feet. Lin Yuan swept through the eight wastelands, killing all the gods and demons in the sky, and carved an invincible path.
