Little did anyone know, the Mecha War King System had activated! He's the ultimate pro at controlling his mech. Handling a Mecha Soul should be a piece of cake! Battle Souls are at their weakest on the night of the full moon? No problem, I've got the Thunderbolt Crescent Slash! Flying beasts are hard to hit? Take this, Skyfeather Dragon-Slaying Dance! Giant apes are incredibly strong? Try my Polar Sandstorm! Just when everyone thinks Luo Xiaoluo is a technical genius, sorry, but he's also got a Mecha Soul with insane stats! What do you mean, his Dragon-Shaped Mecha Soul takes out an enemy in one move?! Luo Xiaoluo: Oh, I forgot to tell you. It's called Dragon Emperor's Other Dimension! Controlling his Mecha Soul, Luo Xiaoluo overcomes every obstacle, reaches the peak, and becomes the youngest Divine-Rank Battle Soul Master.
