Runeterra: the Sword Demon Possesses Me and Becomes My Little Brother!

Nu Yan traveled to Rune Land and unexpectedly obtained the inheritance of the Star-casting Dragon King on the top of the starry sky of Mount Targon, but he also signed a three-year contract with the Dragon King. Three years later, Nuyan left Targon and entered the first region of Runeterra, Shurima. As soon as he set foot in Shurima, he was chased by the dark sword demon Aatrox. He tried to plunder Nuyan's demigod body, but was unexpectedly pressured by the Starforged Dragon King and was completely sealed in Nuyan's body... So the sword demon reluctantly became Nu Yan's younger brother and followed him to travel across the Rune Continent. Of course, he was inevitably ridiculed by Orn and Pan Sen... "Hey! Mortal, you said you wanted to find a true god-level body for me!" "Don't worry! I have plenty of body! But first, you teach me how to seduce Kasha!" "Hmph! That's not easy. I thought back then, in order to chase the Twilight Star Spirit, Zoe, I volunteered to be her licker..." "Shut up, you!" This novel and its characters are purely fictitious.
