From then on, he gathers the power of countless worlds within himself, conquering the world and becoming invincible. "Winged Azure Wolf, Wu Ku, the Bo City disaster? Hah! What a joke! Take this, Zeruel Beam!" "The Magic City Cataclysm, Cold Moon Eye, today you'll taste the fusion of Heavenly Flames: Buddha's Wrath Flame Lotus, burn the heavens and boil the seas!" "Angels of the Holy City? Scum of humanity! I can't be bothered to reason with you. You're not worthy of hearing it! Apollo, Corona Light!!" Mo Fan: "Whoa! He's got cheats! He's got cheats! I can't play this game, not at all!" Ye Xinxia, Mu Ningxue: "He is the only light we have." The Dark Kings: "Damn it! What the hell is that giant with two sunflowers on his shoulders, radiating such overwhelming light?" Many years later. Yu Yuan stands high in the sky, surrounded by the Twelve Talismans that make him immune to every spell. Emperor Flame floats in his hand, burning away evil. The divine beast Celestial Crystal raises its head beside him, while warriors of the Motorbike and Beast clans stand to either side alongside powerhouses like Apollo, Tiga, and the Five Spirits King. Looking down at the several Rooftop Emperors and countless demons, Yu Yuan's voice booms like thunder, shaking the world. "Now, I have everything I need!" "From this day forth, I will purge the world of demons!" Fight violence with violence, defend the Way with martial might, and wipe every evil spirit from the mortal world!
