After Qin Shihuang wiped out Liuhe and suppressed eight wastelands, he smashed the falling "immortal and demon meteorite" in Dongjun and obtained the core of chaos and interstellar blueprints contained in it. This meteorite is the remains of the "Three Realms Bridge" that broke during the ancient immortal and demon war. The core contains the ultimate secret of space folding and energy sustainability. With the ambition of "I am the Son of Heaven, I shall unify the three realms", the First Emperor recruited skilled craftsmen, alchemists and strangers from all over the world. Using the meteorite core as the center, he built a super hub spanning the realms of immortals and demons on the Nine Heavens. He named it "Xuanqiong Palace". It not only inherited the shape of the ancient immortal palace, but also contained the ultimate technology of future civilization, becoming the absolute core to control the three races of humans, immortals and demons. The protagonist, Lu Xinghe, is a villager in a remote town. When he was fishing by the river when he was a child, he picked up a fairyland artifact and started a cheating version of his life.
