From the Start, Alien Races Roast Me, but I Don't Give a Duck

Not a brainless power fantasy. The protagonist is not invincible. No transmigration, no being reborn, and the villains never get dumbed down. Two male leads. An ensemble story, where every star shines! The supporting characters deserve their own moments of glory! There will be plenty of emotional storylines. The supporting characters are flesh and blood, too! How do you fight villains who never get dumbed down? Become a mad dog and tear into them relentlessly. Male Lead One: Why does my golden finger System make me fight in World War II from the start? And why am I defending the last stronghold of Stalingrad? The System even wants to give me a split personality and create a second persona. This piece of junk is disgusting. Male Lead Two: I start with a crimson-red lump of iron to forge a sword. The whole blade is red, with five ears of wheat carved into it. Is this sword not a little too weird? Fate made the two of them children of destiny, but since they would bring misery to the world, they became children abandoned by heaven instead. Male Lead One: But why are beast-eared girls still coming near me? Look at the state I’m in! Male Lead Two: You have to keep your gun under control. Otherwise, you’ll betray humanity and blow us both up like firecrackers. Male Lead One: I’m a seriously cool fire mage! Male Lead Two: A sword cultivator who fights solely to let the crimson banner in his heart fly across the world. What do you do when you run into an enemy you can’t beat? Bite down like a mad dog and fight as if your life depends on it. The villains never get dumbed down! Important things should be said three times.
