Seafaring: Guarding Impel Down, I Emerge Invincible

Ron transmigrated into the world of pirates and spent eighteen years working his way up to become a Navy rear admiral.

He was hailed as the strongest of the Navy's younger generation.

But after killing a Celestial Dragon on a mission, he was demoted and thrown into Impel Down.

Fortunately, Ron successfully activated the System.

Imprison Golden Lion Shiki and receive the reward: Conqueror's Haki at max level.

Imprison Whitebeard Newgate and receive the reward: the Tremor-Tremor Fruit.

Behead Fire Fist Ace and receive the reward: Ryujin Jakka.

The moment Ron walked out of Impel Down, storms raged across the sea.

"Imu, you'll pay for all the crimes your Celestial Dragons have committed over the years!"

A massive hand descended, wiped the Celestial Dragons off the face of Mary Geoise, and snatched up Imu, who had only just woken up.
