My Ten Thousand Souls Banner Gains a Ghost Every Minute, Keep Taunting Me

[If you don’t work hard at cultivation, you’ll become brothers inside the Human Emperor Banner] In the world of Blue Star, ferocious beasts have descended, and everyone can awaken a natal spirit weapon and become a powerful figure. But Gu Yu only awakened an E-rank banner spirit weapon. Fortunately, the Spirit Weapon Evolution System appeared, adding one ghost every second! Even more astonishing, he discovered that his E-rank banner spirit weapon could be upgraded without limit! 100 ghosts to upgrade it to a D-rank spirit weapon! 1,000 ghosts plus one D-rank powerhouse to upgrade it to a C-rank spirit weapon! 10,000 ghosts plus one C-rank powerhouse to upgrade it to a B-rank spirit weapon! Gu Yu was thrilled! A hundred million, a billion, ten billion: the Soul Banner evolved successfully. With a wave of his hand, strange creatures descended in a world-spanning tide! An invincible legend was born across all of Blue Star... Many years later, gods passed through the world of Blue Star. They looked down at its magnificent landscape, bared their fangs, and prepared to swallow the world whole. Gu Yu opened his eyes and rose to his feet. “Gods, I have already laid out the Myriad Ghosts Slaying Heaven Formation. Come and join me inside!” When the gods entered the formation, which blotted out the sky and seethed with chilling winds, ghostly wails, and howls, they were scared witless: “How are there more gods inside your formation than there are of us?” Gu Yu’s indifferent voice rang out: “No gods may set foot in Great Xia!”
