Chapter Summaries

Luo Yi began Zephyr's Black Body Flow training in the deep sea, where the crushing pressure would toughen his entire body. Zephyr ordered him to spend a month adapting, but Luo Yi decided to use his Fruit Encyclopedia for points to accelerate his progress.

• Luo Yi realized Zephyr's Black Body Flow trained the whole body and wondered why few people could learn it.
• Zephyr explained that Ability Users could not train in Black Body Flow and that most people could not endure its environment.
• Binz opened the training platform, and Zephyr sent Luo Yi through a coated pipe to a depth of five thousand meters.
• Zephyr kicked Luo Yi out of the pipe into the deep sea, where he endured intense water pressure and pain.
• Zephyr told Luo Yi to adapt to the pressure for a month before beginning formal training, while privately admiring his physical strength.
• Luo Yi complained that the training would take too long and called on the Fruit Encyclopedia to give him points.

Luo Yi adapted to the pressure five thousand meters beneath the sea after equipping the Slicing-Slicing Fruit, and Zephyr led him to the Marine Giant Gyre for formal training. Zephyr split one of its Black Snake currents with a powerful Haki technique, leaving Luo Yi eager to learn it.

• Luo Yi straightened under the deep-sea pressure, and Zephyr confirmed that he had adapted without injury.
• Luo Yi’s Light Screen revealed that the Slicing-Slicing Fruit had strengthened his body’s hardness to steel.
• Zephyr led Luo Yi deeper beneath Marineford, where they encountered the Black Snakes of the Marine Giant Gyre.
• Zephyr explained that Luo Yi’s training required him to resist and defeat the Black Snakes.
• Zephyr demonstrated his Black Body Flow Secret Technique: Mountain Collapse, punching a hole hundreds of meters wide through an undersea current.
• Luo Yi watched Zephyr’s technique in amazement and decided that he wanted to learn it.

Zephyr trained Luo Yi in Black Body Flow, pushing him to endure the deep-sea currents and control his body while revealing his great potential for Armament Haki. Luo Yi sensed his Haki for the first time, but Zephyr’s estimate that mastering it would take years left him wishing for a Haki Fruit.

• Zephyr demonstrated Black Body Flow’s ultimate technique and explained how it coordinated control of the body with Haki.
• Luo Yi trained in the deep-sea currents as Zephyr repeatedly rescued him and corrected his movements.
• Luo Yi grew stronger through the repeated strain and recovery, then sensed a power within his body that Zephyr identified as Haki.
• Zephyr explained that Luo Yi could draw out Haki in about half a year, use it proficiently in one or two years, and reach Zephyr’s level in about ten years.
• Luo Yi balked at the long timeline and wondered whether a Haki Fruit existed, while Zephyr ordered him to complete ten more training rounds.

A month after Crocodile’s defeat, Dragon reorganized Baroque Works and assigned its assassins to gather intelligence for the Twelve Zodiacs. MR.4’s account of finding Lassoo in a vanished laboratory led Dragon to suspect it belonged to Vegapunk, near Water 7, where the Devil Fruit he sought was also located.

• Dragon told the Baroque Works assassins that he was their new MR.0, that Crocodile was dead, and that their operations would change under the Twelve Zodiacs.
• MR.1 questioned Dragon’s story, but the assassins accepted the change in leadership, and MR.3 pledged his loyalty alongside Miss Golden Week.
• Dragon assigned the assassins sea regions and ordered them to gather intelligence on valuable items, including gold and Devil Fruits.
• Lassoo barked at a location on the Sea Chart, and MR.4 explained that he had found the weapon in a laboratory after surviving a shipwreck.
• MR.4 said the island had vanished when he and Lassoo returned, and Dragon recognized that its location was near Water 7.
• Dragon suspected the laboratory was one of Vegapunk’s early facilities and recalled that the Devil Fruit he needed was also in Water 7.

Luo Yi used a mission assigned to Fal and Hans as a chance to leave Marine Headquarters for Water 7. He joined the Detention Unit aboard a newly refurbished warship that the Marines had named after him, and ordered them to set sail.

• Luo Yi decided that traveling to Water 7 himself was the safest way to obtain the fruit he wanted and investigate the Vegapunk laboratory.
• Binz told Luo Yi that Zephyr was away testing the Crusher and that Fal and Hans had come to invite him on a mission assigned by Vice Admiral Billoss.
• Luo Yi agreed to go with Fal and Hans, seeing the mission as a convenient reason to leave Marine Headquarters.
• Luo Yi reunited with the Detention Unit Marines, who showed him a refurbished warship designed like a bottle of cola and named [Loy (Luo Yi Amos)].
• Luo Yi accepted the warship and ordered his crew to set sail.

Luo Yi considered taking his Marine warship to Water 7 when his crew spotted the battered Spadille, carrying the injured Spade Pirates. He ordered his ship alongside, while Ace launched a fiery attack, convinced he could deal with the Marines in one strike.

• Luo Yi contemplated using ship repairs as an excuse to visit Water 7, but Hans had already completed maintenance on the warship.
• A lookout spotted a pirate ship, and Hans and Fal identified it as the Spadille, the ship of Portgas D. Ace’s Spade Pirates.
• Fal and Hans urged Luo Yi to withdraw and report the pirates, but Luo Yi ordered the warship to come alongside.
• Deuce worried that the injured Spade Pirates might have to fight the approaching Marines after escaping Hanafuda’s pursuit.
• Ace told Deuce he could handle the warship with one strike, then leaped into the air and launched Fire Fist.

Luo Yi, newly strengthened to Great Buddha Form LV3, faced Ace’s Fire Fist and answered with a devastating Wave Fist that split the sea and battered the Spade Pirates’ ship. Ace protected his crew from the attack, but the ship was left wrecked as Deuce realized how dangerous Luo Yi was.

• Ace’s Fire Fist met Luo Yi’s shock wave, and Luo Yi held the flames back from the warship.
• Luo Yi’s fruit enhancement advanced his Great Buddha Form from LV1 to LV3, and he shattered Ace’s flames with a stronger punch.
• Luo Yi used Wave Fist: Infinite Light, splitting the sea as Ace abandoned Elementalization to shield the Spade Pirates’ ship.
• Ace countered with Mirror Flame, but Luo Yi’s shock wave dispersed the fire wall and severely damaged the Spade Pirates’ ship.
• Deuce obeyed Ace’s warning to get down, then saw the ship’s bow figure, masts, and rear cabin had been destroyed.

Luo Yi struck Ace and the Spade Pirates with a devastating shock wave, but Ace chose to flee rather than risk his crew in a prolonged fight. As Luo Yi prepared to pursue, Hanafuda’s fleet arrived and attacked the Marines’ warship.

• Luo Yi’s punch overwhelmed Ace’s flames and devastated the Spade Pirates’ deck, leaving Ace injured and his crew alarmed.
• Deuce urged Ace to escape because Hanafuda was still pursuing them, and Ace agreed to protect his companions.
• Ace used the Spade Pirates’ ship’s machinery and his flames to propel it away like a rocket.
• Luo Yi reflected on his growing strength and began preparing to pursue the fleeing pirates.
• Hanafuda’s seven-ship fleet appeared, fired on the Spade Pirates, and blasted the Marines’ warship from behind.

Luo Yi’s Marines were injured when Hanafuda’s fleet accidentally struck their warship, and Luo Yi decided to retaliate. As Hanafuda’s ships bore down on them, Luo Yi unleashed a freezing Wave Fist, leaving the blow’s impact unresolved.

• The Detention Unit learned that Hanafuda’s stray shots had damaged their ship and left Morr and Lanster injured or missing.
• Luo Yi ordered his men to search for the injured Marines and repair the ship, then said he was calm enough to beat Hanafuda to a pulp.
• Luo Yi noticed that Hanafuda’s Giant Dinosaur Fleet was heading straight toward their warship, while Hanafuda focused on pursuing Ace and dismissed the Detention Unit as weaklings.
• Hanafuda’s ships struck ice that formed across the sea, and he recognized Luo Yi leaping toward them with Geppo.
• Luo Yi attacked Hanafuda’s fleet with Ice Wave Fist: Eternal Frost.

Luo Yi froze the sea and destroyed most of Hanafuda’s fleet with a second, fiery Wave Fist attack, then explained his powers to the Detention Unit as new forms of Fish-Man Karate-inspired Wave Fist. As Luo Yi’s crew returned to the wrecked flagship, a monstrous figure emerged from the smoke and roared at the Marines.

• Luo Yi froze the sea around Hanafuda’s fleet, trapping its ships and stopping the Tyrannosaurus.
• Luo Yi launched Flame Wave Fist: Boil Sea, engulfing Hanafuda’s fleet in flames and a shock wave as Ace and the Spade Pirates watched from afar.
• Ace and Deuce recognized Luo Yi’s attack and concluded that Hanafuda’s fleet had been destroyed.
• Luo Yi returned to the warship and told Hans and Fal that his ice and flame attacks were new branches of Wave Fist inspired by Fish-Man Karate and other techniques.
• Luo Yi clarified that defeating Hanafuda in one strike would still be difficult, then a huge monster emerged from the smoke and roared at the Marines.
