One Piece: The Old Guard's Powerhouse, Making Imu Panic!

[Invincible + Hilarious + A Senior’s Overwhelming Advantage + Pure Physical Basic Attacks]

Lei En transmigrates into the world of pirates, where he spends forty years sleeping on autopilot in Impel Down before awakening the [Extreme Stats System]!

No flashy Devil Fruit powers, just physical defense exceeding one billion and a max-level basic attack that shatters space with a single punch!

Now the living ancestor from the Rocks era has busted out of prison, and the brats of the New World are about to receive a true “physical send-off to the afterlife”!

…

The Paramount War takes an unexpected turn.

Magellan unleashes poison dragons? The old man downs them in one gulp. “Strawberry flavor. Could use a bit more kick.”

Blackbeard uses Black Vortex? The old man gives him a vicious slap. “I haven’t eaten a Devil Fruit. What the hell are you trying to suck out of me?”

Kizaru uses Flash Kick? The old man grabs the beam of light and crushes it. “Why are you using your high beams in broad daylight, young man? Can you afford to pay for my cataracts?”

Looking to claim an astronomical “retirement fund,” Lei En makes a surprise landing at Marineford.

The World's Strongest Man, Whitebeard, tears up and bows in front of everyone. “Big Brother Lei En!”

Fleet Admiral Sengoku breaks into a cold sweat, while the Five Elders’ secret scandals shatter their faith.

Faced with Akainu’s Meteor Volcano, capable of melting anything, Lei En grabs Blackbeard to use as an umbrella, then casually squeezes the magma into obsidian!

…

Then one day, the highest-level doomsday alarm sounds in Mary Geoise.

Imu looks terrified and is forced to activate the Ancient Weapon, Uranus.

But wearing nothing but flip-flops, Lei En kicks Uranus’s laser back into the atmosphere and strolls toward the Empty Throne.

“Imu, you little brat, that chair looks pretty comfy. Get up. The old man wants a turn!”
