Chapter Summaries

Qi Hai, Mia, and Su Hang used decoys and a dangerous maneuver to neutralize six of seven Seastone torpedoes targeting the fleet. The last torpedo locked onto Medical Ship Two, and a government agent challenged Su Hang to unleash Nika’s power if he wanted to save it.

• Qi Hai ordered the fleet to spread out as Mia tracked seven torpedoes closing in on the Dawnbringer.
• Su Hang, Qi Hai, and Mia used weighted barrels and changing sound signatures to lure the first five torpedoes into explosions or a reef.
• Su Hang stretched his arms around the mast while the crew shifted cargo, allowing the Dawnbringer to list and evade two more torpedoes at the cost of a cracked mast and his bleeding shoulder.
• Mia discovered that the final torpedo had changed its target to Medical Ship Two, which carried Brand’s fever medicine and had no room to turn.
• Brand revealed that a government agent controlled the last torpedo, and the agent demanded that Su Hang fully unleash Nika’s power to save the medical ship.

Su Hang saved Medical Ship No. 2 from the final torpedo without revealing Nika's complete form, but a Seastone fragment wounded his leg. The ships completed their passage safely, while Grave decided to use an island's people as a heavier bargaining chip in a future attempt to force Su Hang to reveal his power.

• Su Hang and Qi Hai used the Dawnbringer's anchor and chain to draw the final torpedo away from Medical Ship No. 2, despite pressure from an unfamiliar voice to reveal Su Hang's power.
• Su Hang drove the anchor into a reef, causing the torpedo to follow it and explode; he escaped the shattered Seastone net but was wounded by a Seastone fragment.
• Qi Hai pulled Su Hang back aboard the Dawnbringer, and Captain No. 2 reported that the medical workers and medicine were safe.
• Mia guided the medical ship and witness merchant ships through the route, completing the escort mission without losing a ship or medicine crate.
• Grave reported that Su Hang had refused to reveal his full power and chose to risk himself to save others, then proposed placing an island's people in danger next time.

Su Hang used the Nika Core to break through the lingering Seastone suppression in his leg, but the increased fusion rate triggered uncontrollable laughter, combat impulses, and autonomous ability use. Qi Hai and Mia subdued him with a seawater-soaked sail, and Su Hang was left shaken by how little control he had over his own body.

• Su Hang refused to rest despite his Seastone wound and raised the Nika Core's temporary fusion rate to 20%.
• Su Hang's leg recovered, but his heartbeat and strength surged as he began laughing and rubberizing the medical cabin and deck.
• Su Hang tried to leave to pursue the observation ship, and Qi Hai blocked him while Mia and Chopper tried to stop his rampage.
• Qi Hai dropped a sail over Su Hang, and Mia soaked it with seawater, weakening him before he could strike her again.
• Su Hang regained control and denied wanting to chase the observation ship, but his hand then attacked Qi Hai without his command.
• Chopper concluded that Su Hang's strength had recovered faster than his will could keep up, and Qi Hai warned he would use seawater to stop him next time.

After Su Hang’s Nika Core fusion caused him to lose control and endanger the Dawnbringer’s crew and medicine cargo, Qi Hai, Mia, and Lorne confronted him during a debrief. Su Hang accepted responsibility and agreed to strict limits on his authority and future fusion use, then was asked to sign the new rules.

• Lorne presented the damage report, and Mia’s Weather Wheel record showed that Su Hang had ignored stop orders and attacked Qi Hai during forty-seven breaths of abnormal behavior.
• Qi Hai challenged Su Hang’s claim that he had acted to protect the fleet, and Su Hang admitted that fear of losing his combat strength had driven him to fuse without fully explaining the risks.
• Su Hang acknowledged that he had used the lucky outcome to excuse his decision and agreed to create mandatory rules for interrupting fusion and transferring command.
• Su Hang set restrictions on fusion tests, accepted personal responsibility for the damage and injuries, and agreed that overseers could not be punished for imposing restrictions.
• The system displayed a prompt noting that Su Hang had voluntarily relinquished part of his authority, and Qi Hai asked him to sign the new rules first.

Su Hang received Luffy’s challenge and sent back his old ability records with a warning to prepare before fighting him. Luffy trained under Karp, grew stronger without relying on a Devil Fruit, and vowed to punch Su Hang first when he set sail.

• Su Hang received a challenge letter from Luffy, who claimed he could now beat the wild boars in the mountains.
• Karp trained Luffy in balance, rescue knots, fighting, tides, and currents as Luffy subdued a Blue-backed Boar without continuing to hurt it.
• Luffy told Karp he still wanted the Nika Fruit but would pursue what he wanted through his own speed and strength.
• Su Hang mailed Luffy copies of his old ability-testing records and warned him to learn how not to fall into the sea before their next fight.
• The system reported that Luffy had improved his physical skills, rescue abilities, and navigational knowledge, changing the predetermined fate loop.
• Luffy climbed a warship mast carrying two barrels of stones and told the mail-delivering seabird that Su Hang would be the first person he punched after setting sail.

Su Hang and his crew entered Rogue Town under Smoker’s supervision and used the weather observatory’s records to pinpoint the next Rising Current, which could lead them toward Sky Island. As they prepared to leave, they learned that the sky route had been put up for auction at an underground venue.

• Smoker confronted Su Hang at Rogue Town’s harbor, but verified the crew’s documents and allowed Dawnbringer to enter port for four hours.
• Mia found an old weather chart and a Cloudstone at the observatory, linking a reverse thunderstorm to a route toward Sky Island.
• Su Hang’s bronze compass pointed skyward, and Mia calculated that the next Rising Current would occur in twenty-one days near the East Blue–Grand Line border.
• Smoker warned Su Hang that the World Government might pursue them if they found Sky Island, then let them complete their purchases before leaving port.
• A broker delivered an underground auction token and told Su Hang that the sky route was already up for bidding.

At Rogue Town’s underground auction, Su Hang and Lorne exposed that Belloc’s High-Altitude Imaging Shell contained only half a sky route, disrupting Donquixote Doflamingo’s attempt to obtain evidence against the Navy and Arlong. As they left, a masked figure offered the other half in exchange for Nika’s secret.

• Lorne used the auction rules to secure a public projection of the shell after the guild could not afford Belloc’s bid.
• Su Hang and Lorne showed that the shell recorded only the route to the thunderstorm layer, without the directions needed to cross it safely.
• The bidders erupted in anger, and Su Hang accused Belloc of trying to trade the incomplete route for evidence against the Navy and Arlong.
• Su Hang and Lorne left the auction hall after the bidders forced Belloc to stand down, while Lorne kept the copied first half of the route.
• A white-bone-masked figure waiting in the rain offered Su Hang the other half of the route in exchange for Nika’s secret.

Su Hang traded verified information about Nika’s weakness to seawater for the second half of a sky route, then forced the seller to reveal that the route’s measurements had been falsified. As the Dawnbringer set sail, Grave launched a trap using genuine weather data with a false date, and Mia received an urgent notice claiming the Rising Current had arrived early.

• Su Hang verified the gray-cloaked figure’s recording shell with the Bronze Compass and offered seawater test data about Nika in exchange for the route.
• Lorne and Mia examined the projected route and discovered that the gray-cloaked figure had altered its altitude measurements.
• Su Hang seized Belloc and forced the gray-cloaked figure to reveal the original route data, which pointed the Bronze Compass toward the passage.
• The gray-cloaked figure turned out to be a mechanical Den Den Mushi, while Grave ordered agents to lure the Dawnbringer into White Tower Strait with a false early-current date.
• Mia received an emergency message claiming the Rising Current had arrived early and that the crew had three hours to catch it.

Su Hang exposed Grave’s trap at White Tower Strait and glided into the tower, where he discovered a World Government causality experiment. Grave triggered the tower’s flooding and escape sequence, leaving Su Hang to choose between pursuing him and saving the trapped researchers.

• Su Hang rejected the forged Rising Current report but took the Dawnbringer to White Tower Strait and exposed the Seastone net and hidden wires.
• Grave claimed Su Hang had missed the current and revealed that he knew about Opportunity Interception Determination; Su Hang identified the tower as a World Government research facility.
• Su Hang glided in from the northwest while Mia used balloons and white ash to reveal the wires, then he evaded a cannon and entered the observation room.
• Su Hang fought past the guards and confronted Grave, who activated the tower’s self-destruct sequence and fled down the escape ladder.
• Su Hang found researchers trapped in flooding watertight chambers as Grave warned that the tower would sink in ten minutes, forcing Su Hang to choose whether to pursue him or save them.

Su Hang and the Dawnbringer crew rescued the researchers, brought down White Tower without hitting their fleet, and captured Grave with the help of Qi Hai’s escape-route trap. They assembled the route to Vika, where Su Hang set out to intercept the Rumble-Rumble Fruit as its original recipient approached.

• Su Hang broke through White Tower’s compartment, evacuated the researchers, and shifted the collapsing tower away from the Dawnbringer.
• Qi Hai trapped Grave’s speedboat with buoys, captured him, and recovered the surviving fragments of the file case.
• Mia combined the recovered documents and navigation records to confirm the complete route to Vika and the Rumble-Rumble Fruit.
• Su Hang ordered the route archived for guild members under confidentiality rules, and the system reported increased Cause-and-Effect Lighthouse brightness.
• Imu rejected the Five Elders’ proposal to seal the Rising Current and allowed Su Hang to continue toward Vika.
• The Dawnbringer prepared to sail for Vika as the system warned Su Hang that the Rumble-Rumble Fruit’s original recipient was approaching it.
