[Mecha] + [Firearms] + [Comedy] + [System] + [Dog of a protagonist] + [No heroine]
Lin Xiao, a military hardware enthusiast, transmigrates to a fantasy world full of cultivators.
The System comes along with him.
But who could have guessed?
The System stays stuck for ten whole years. With his unusual physique and glacial cultivation speed, Lin Xiao has no choice but to become an honorable manure-hauling disciple of the Qingyang Sect, resolving to haul manure and keep his head down for the rest of his life.
Until one day.
[Ding-dong~ The Invincible Mecha Weapon System is online.]
Lin Xiao looks at the weapon tech tree in the System and falls silent.
Anti-materiel sniper rifles, assault rifles, submachine guns, flamethrowers, uh... nuclear bombs?
Collect the materials, and he can unlock the corresponding weapons.
And that's not all. Besides all kinds of weapons and tactical gear, the System also provides incredibly powerful mecha as his cultivation improves.
From then on, while others cultivate immortality, Lin Xiao cultivates mecha.
While others project spiritual energy and unleash their Dharma forms, Lin Xiao points a giant cannon at their faces and overwhelms them with firepower.
Many years later.
“Lin Xiao, get over here and die!”
Looking at the densely packed cultivators across from him, Lin Xiao silently pulls out a cannon as big as a hill.
After one shot, every cultivator meets their dearly departed grandmother on the spot.
Faced with enemies as numerous as mountains and seas, fierce beyond measure,
“Lord Lin Xiao, how should we attack?”
Lin Xiao: “How should we attack? I'll sortie in Gundam mode.”
That night, his enemies, who had cultivated immortality their whole lives, got their first taste of beam sabers, funnels, and supercharged laser cannons.
Ten thousand years later, thunder rolls.
Lin Xiao pilots his mecha, pointing a beam saber at the heavens.
Flesh is weak!
Behold!
Mecha Ascension!
[Staring] Give yourself a thumbs up for your hard work.
At the beginning, the protagonist is marked as a slave. If you can watch it, watch it.
That's it. All without intelligence
I think it's still pretty good
