Slay the Gods: There's a Primordial World Inside Me!

My name is Chu Chen, and I've arrived in the world of Slay the Gods. The good news: I got a golden finger. The bad news: this golden finger took three years to load! The System is recreating the entire primordial world inside me, the most glorious era of all! Three thousand gods and demons! The Twelve Ancestral Witches! The First Kirin, the Phoenix, and the Ancestral Dragon, all gathered together! According to the System, once the recreation is complete, it will leave. As for me, I can use incantations to summon these gods, demons, and immortals into reality! [Primordial Deity: Donghuang Taiyi] "The radiant sun, source of all flames! Your disciple offers the Nine Heavens' lightning sigils as a pledge, and the mountains and rivers of the Ten Directions as a sacrifice. I humbly beseech Donghuang to manifest in the mortal realm! Let the bell ring through the cosmos and subdue the Eight Wastes; let the Golden Crow burn away the evils of every heaven! Taiyi above, let all gods stand aside!" [Great Sage of the Demon Tribe: Kunpeng of the Northern Sea] "In the Northern Sea swims a fish, whose wings hang from the sky! It drinks the starry sea and soars through the Great Void, bearing the weight of Heaven and Earth! Now, with a hundred thousand demon souls as my guide, I call your true name: Ancestor Kunpeng, swiftly transform yin and yang, and tear this chaos apart for me!" [Ancestral Witch of the Witch Tribe: Houtu, Empress of the Earth] "Murk of the Nine Hells, heed my command! Lady Houtu bears the weight of the earth's veins and holds the pivot of reincarnation. Let the Yellow Springs surge into the netherworld; let the lotus of the Six Paths bloom to ferry the dead! With my blood, I draw a blood-sha totem. I beseech the Ancestral Witch to enter this world and guard the dragon veins of the Nine Provinces!" The Outer Gods invading Daxia looked at the lineup behind Chu Chen and trembled. What the hell? How are we supposed to fight this?
