[Transmigrated into a pirate world + 100x system + intense battles + using battle to sustain war]

Yun Ying, a martial arts grandmaster in her past life, died and transmigrated to the CP9 training camp, becoming the most dangerous cannon fodder. In her despair, the [100x Feedback System] activated! Training effects were amplified a hundredfold! Combat insights were accelerated a hundredfold!

While others toil for ten years, he progresses by leaps and bounds. Six styles? I casually modified them, transforming them into the [Ultimate Six Styles], without stiffness or weakness! Overbearing aura? I easily awakened it, fusing the three colors to forge the [Overbearing Armor]! A long spear, I created the [Nine Styles of Star Piercing], from "Meteor Piercing the Sun" to the ultimate "I Am the Heavenly Punishment," vowing to pierce through the stars!

* Core Secret Technique: "A flash of cold light arrives first, then the spear strikes like a dragon!" All the body's essence, energy, and spirit, along with the Overlord's aura, are concentrated at the tip of the spear, its penetrating power surpassing even the ocean!

Unable to tolerate the darkness of the World Government, he brazenly defected and began a reverse hunt for CP0! Aokiji's Ice Age? A hundredfold enlightenment, instantly unlocked! An attack by the Admirals? Perfect stepping stones to my ascent! This is the epic tale of a battle maniac who, with the hundredfold system, sweeps away everything with his spear, pursuing the ultimate in combat and freedom!

Xia Chen unexpectedly transmigrates to the world of One Piece, activating the story island check-in system right from the start.

"What? You get stronger just by clearing story islands? Doesn't that mean you're about to take off?"

Upon visiting the first island, Windmill Village, I obtained the Zoan-type Mythical Beast Fruit, the Great Sage Equal to Heaven form!

Is Nika the Sun God really that powerful?

Do you know that even if you become a god, you're just one of the 100,000 heavenly soldiers and generals who can stop me?

He then happens to meet Luffy, who is just about to set sail, and at Luffy's invitation, becomes the vice-captain of the Straw Hat crew.

Join the main characters as they explore story islands and grow stronger!

What you think this book is: "What? I still hit pretty well." "I'm the man who turns the impossible into the possible!" "Style! Invincible East!" "Mission accomplished, self-destruction begins!" "The moon is out!" "Are you going to start another war?!" "Happy birthday~" What this book is actually about: Actually, I want to be a good person! Trying to pilot a Gundam so quietly? Honestly, send watermelon ice cream one by one! It's just an orbital elevator, watch me push it back! If you escape from the cockpit, your pilot career is over! Leo's performance will vary greatly depending on the pilot's ability! The author was hit by a colony satellite… The End.
