At the age of six, Lila Voss was sent down the mountain by her master to gain cultivation experience, and to search for her five long-lost senior brothers. She originally thought her senior brothers were ordinary cultivators living a modest life. But as she searched along the way, she found that Senior Brother Orion was the supreme immortal who rules the world, Senior Brother Jasper was the demon emperor who governs the netherworld, and Senior Brother Cain was the alchemy sage. The little girl carried a tattered black iron greatsword, traveled across the immortal cultivation world with an ancient divine beast, and easily brought all five peerless powerful senior brothers back home.
