Armor Hero: I Become Homelander with a Superman Template

Armor Heroes 1, 2, and 3 + Silver Superman + invincible + Homelander + Dark Emperor Armor + comedy + multiple heroines

Lu Dong transmigrates into the Armor Heroes world and becomes Feng Ying's cousin. Thinking he'd lead an uneventful life, he encounters the Nether Demons and gains the God-Tier Choice System. From the start, he gets the Silver Superman template and becomes a reality-warping superhero.

He can do whatever he wants, and no one can stop him. Mutant Beasts, Nether Demons, and Oukesers appear one after another.

With his super-intellect, he cracks Ares technology and develops even more powerful standard-issue armor. An army of a million armored warriors takes the field, Daxia rises to become a Level Seven civilization, and it ascends to become a universal hegemon.

When the Cosmic Bug Beast appears,

Lu Dong arrives in a Homelander suit and looks at the Oukeser God. “Since when do bugs get to butt in?”

General Duan Muyan steps forward. “Standing before you is the God of the mortal world, the wielder of Heavenly Dao Armor, the master of the Shadow Realm, the King of Ares, and Director Lu of our 749 Bureau. But you won't get the chance to face him. Netherworld Shura, merge!”

Bei Miao: “A rotten orange is still a rotten orange. The captain uses his ultimate move like a basic attack, and a little bug thinks it can challenge him? Earth couldn't withstand his power.”

Xiao Gang: “Director, I gave away every summoner in the whole regiment.”

An invincible story with multiple heroines. The protagonist isn't impotent, so don't read if that's not your thing.
