Between the vast and vast world like the sea of stars, there is a mysterious and fantastic world hidden - the world of weapon spirits. This is a fantasy land where high martial arts and aura blend with each other and sparkle. Here, all living things are favored by the aura and all have spiritual connections. Those magical weapons forged by skilled craftsmen with painstaking efforts, under the baptism of the long years, constantly absorb the spiritual energy between heaven and earth, and then nourished with the user's essence and blood, miraculously gave birth to extraordinary spiritual weapon spirits. These weapon spirits have various appearances, some are like the delicate flowers blooming on the branches in spring, as cute and cute as a cardamom girl, with lively and playful eyebrows; some are like battle-hardened generals, cold and majestic, exuding a chilling aura of chilling. They not only possess extraordinary wisdom, but also possess the powerful power to destroy the world. They form a life-and-death bond with their contractors, ride side by side in this magnificent world, and embark on a series of thrilling adventures.
