Everyone Else Levels Up by Killing Monsters, but You Speedrun the High Martial World with a Gun?

【Invincible + Leveling + Stat Monster + Adults Eat Shit】(Enter at your own risk if you don't like it) "My sword is swift as the wind and fast as lightning. One stroke can even open the gates of heaven!" "But Lin Yan just shot the gates of heaven to pieces with a Gatling gun." "My blade is as heavy as a mountain and fierce as the tide. One strike can split rivers and mountains!" "But Lin Yan blew up a planet with a sniper rifle just yesterday." Spiritual qi revival transforms Blue Star, ushering humanity into a high-martial-arts age of class awakenings! Some awaken the S-rank Mage God class and can destroy a nation with a single forbidden spell! Others awaken the A-rank Mechanic class and can build a Gundam with their bare hands! But Lin Yan awakens an unprecedented, lowest-tier E-rank class: Asura Walker. His teacher sighs. "You may not be fit for the battlefield, but you're still worth studying. You can go to the research institute and serve as a test subject." His classmates laugh. "Your class isn't even enough to get stuck between a ferocious beast's teeth." But no one could have imagined it. Lin Yan's class talent isn't E-rank. It's the beyond-the-system EX rank! His class also comes with an outrageously powerful skill! 【Unerring Accuracy】: Attacks automatically track enemies! If attacks can track their targets on their own, who needs a bicycle? I don't eat beef anyway! While his classmates are still fighting mutated beasts with swords, fists, and kicks, Lin Yan has already quietly hoisted a Gatling gun from afar. Have you ever seen a Gatling gun that never misses? Have you ever seen a sniper rifle that can hit its target with pinpoint accuracy from ten thousand miles away? Lin Yan: As long as I can see you, even if you're a god, you'll be on your knees!
