Is there any hope for this nation's future? "In short, the Three Clans Conference has decided that you will be the first Speaker of the Kjerag National Assembly." Ernst Shivaash sighed deeply at his brother, Silver, who has always been a misfit.

I'm on Terra, newly appointed Prime Minister. How do I govern this strange little nation?"

He used all the treasures in the world that could enhance power, including the Divine Seal Praise and the Heavenly Seed, on the water element.

"Why is it that Young Master Mingzhu's water weapon is different from ours?" someone asked.

When the Ocean God Clan invaded China, Hua Yu stepped forward, pointed into the void, and laughed loudly, "You think you can compete with me in controlling water?"

......

PS: I won't steal Mo Fan's opportunities, and I won't break up the original couple.

Rune, a mediocre wizarding apprentice whose future hangs in the balance, suddenly finds himself transported to another world… “Transportation by horse? Duels by sword?” “So-called noble knights… are nothing more than a bunch of muscular, weak-willed brutes?” A sly smile crept across Rune’s lips. “In the wizarding world, you call me apprentice, and I won’t argue…” “But in this ignorant Middle Ages, what should you call me?”
