Saintly Flesh: Become Stronger by Beating Everything to a Pulp

Invincible Protagonists Who Stay Strong the Whole Time, No On-and-Off Power. Ideally Invincible from the Start

Campus Novels with a Huge, Muscular, Fierce-Looking Male Lead and One Female Lead

Hehe, I've run out of books to read.

System + Body Tempering + Creepy Monsters

A Physically Powerful Protagonist Who Wields a Heavy Hammer

Hard-Body Training, Muscles, Cold-Blooded Leads, and Body Cultivation. The Protagonist Is Built Like a Monster

No pretty boys, no handsome guys. The uglier and more vicious, the better. Crush the eldritch god with one hand.

A Golden Finger, Something Like the Demon Suppression Bureau

An ancient imperial setting, perhaps with the protagonist joining the Six Fan Gate, the Embroidered Uniform Guard, or the Demon Suppression Bureau. It should feature demons and monsters, a domineering protagonist who kills decisively. A villain protagonist is fine too.

Body-Tempering! Stat Points! Proficiency! Skills and Techniques!

Invincible Through Physical Strength Alone, With a Bigger Protagonist Being Better

Any kind of setting for fanfiction is fine, preferably one with a huge worldbuilding scope.

A Male Lead with an Invincible Body, Iron Body Training, and the Power to Smash Everything

Hard-body training. Body cultivation.

Body Tempering, Extreme Martial Arts, Martial Studies, and the Supernatural

Musclebound, Unstoppable Strength, and Brute Force in the Apocalypse

Smash Everything with Your Bare Hands
