We're Already in Duel City, Who's Still Summoning Me Normally?

Bad news: Traveling through Duel City, you were beaten to death by the national champion at the beginning! Good news: Awaken the [Duel King System] and unlock the modern forbidden card construction! Zhao Jun traveled through the world of Yu-Gi-Oh!, This world—— The summoning of sacrifices is as slow as a turtle crawling! Mortal bone monsters fight each other to become king! With three thousand attack power, you dare to claim to be invincible! Holding a mortal bone in his hand, he was laughed at by everyone until the system prompts: [Ding! Activate True Red Eye Fusion to summon 2800 points of Black Blade Dragon with one card! [Ding! The Pot of Desire draws cards at no cost, and the True Red Eye Triumphantly resurrects infinitely! "You don't even have to summon a monster, and you still want to win?" The champion laughed wildly, but he didn't know... The next second, Zhao Jun backhand shot the Dark Steel Dragon with an attack power of 4600, clearing 4,000 health bars in one blow! When Kaiba's blue-eyed white dragon was instantly crushed, all the duelists in the audience collapsed completely, but little did they know... Zhao Jun sneered and took out the ultra-modern black magic card deck. The magic array radiated light across three thousand states and suppressed one hundred thousand gods! They're all in Duel City, but who's still doing normal summons? !
