You Say I’m Obsessed with Music? I Signed In as an Earthly Immortal!

[A prince exiled overseas + sign-in to the Land Immortal realm + the struggle for the throne among nine princes + an unstoppable rise and thrilling victories + Wei Wu keeps swinging his whip] There is no one like me in this world. I hold the sun and moon and pluck the stars! I carry an unyielding fury that can open the Heavenly Gate and sever the Three Realms! Transmigrated into the body of a prince? Don't celebrate just yet! He's a useless wastrel who only knows how to listen to music, and right now a kidnapper has a sword at his throat! Luckily, at this critical moment, he awakens the Super Martial God Sign-in System. As long as he checks in at designated locations, he can keep growing stronger. He also gains a training arena, the Bronze Sparrow Terrace, the ability to summon famous ministers and fierce generals, an incredible illustrated guide that grants him the power of its subjects, and other heaven-defying features! If listening to music can make him stronger, then this prince won't hold back. Let the music play and the dancing continue! See how Zhou Yi rises from Bibo Island in Borneo overseas, then opens the Heavenly Gate with a single sword strike, reaches the Land Immortal realm, and returns home to seize the dragon throne, stunning the world!
