I Am a Magic Gun, Helping Zhao Yun Fight the Three Kingdoms

[Time Travel + Alternate History + Black Humor] My name is Lao Tie, yes, a gun. A professional troll, a lifelong honorary member. A second ago, I was in the crunching mud of Ukraine, listening to Katyusha rocket launchers singing a duet to me. The sound of the shells falling to the ground was duang duang, louder than my grandfather's snoring. The next second, I was dug out of the ground. In front of me was a handsome young man who called riding a horse a "Gundam" and called my cold iron lump a "magic weapon descended from the sky." This guy's name is Zhao Yun. He has an upright face and a mind filled with benevolence, justice and morality. The look in his eyes when he looked at me was as bright as a searchlight, and he almost knocked me out. I wonder if this is nonsense? Divine weapon? Dude, I'm just a killing tool coming off the assembly line. My only superpower is that bullets don't cost money and I still care enough. Ever since, a silly Baitian with classical heroism, coupled with me, a modern veteran who always said "I'm crazy, just do it", our careers started flying like crazy in the troubled times of the Three Kingdoms. They all say that Zhao Zilong from Changbanpo (Yichang, Hubei Province) enters and exits seven times. That is a myth. Fart! It was the two of us who defeated KDA! But as I kept killing, I realized something was wrong. I watched these stupid roe deers, like moths rushing to the flame, risking their lives for the sake of that illusory "righteousness", one after another. I looked at that boy Zhao Yun, covered in blood, but there was still light in his eyes. He was protecting the crying baby in his arms and charging over and over again.
