After Controlling the Most Powerful Element, I Am Invincible!

[National job transfer + no heroine + upgrade + passionate invincibility + defending the home and country + not hiding + tactics] Chen Yi traveled to a world where everyone changed their profession and became an intermediate professional elemental mage at the beginning. System: "What? Only intermediate level?" "Congratulations to the host for completing the mission, and the reward is the only hidden profession, the elemental mage plllllllus version - the elemental ruler!" "The fire element was upgraded to Sky Fire, the thunder element was upgraded to Nine Heavens Divine Thunder, and the ice element was upgraded to Ultimate Ice..." From then on, sky fire, thunder and lightning, ice, light, darkness... Countless elemental powers capable of destroying the world slowly flowed through Chen Yi's fingertips. The gods above the sky panicked: "Please quickly withdraw your magical powers!" The devil from hell regretted: "I shouldn't have invaded Daxia at this time!" The Queen of the Abyss turned pale: "As long as you spare my life, I am willing to work as a cow and a horse for you!" Whatever weird things, whatever ferocious beasts, were all destroyed by Chen Yi in one blow! The fragmented human race once again saw the light of hope and stood up from the ruins. "Who said there is no great emperor in the human race?!" "The sword points to the gods, God bless Daxia!" Chen Yi stood on the abyss: "Everyone, starting from today, the offensive and defensive positions will change!" The power of the elements in the world is controlled by me alone, since I am eternal!
