Sun Keiyun encouraged Wu Guanglu to turn his art into comics and helped him begin The Adventures of Sanmao the Orphan. After Lina revealed that she would accompany Sun Keiyun until his identity was disclosed at Liu Xu’s birthday banquet, he worried that she would interfere with his plans.

Sun Keiyun used the Great Soul Shifting Technique from the Chat Group to awaken Observation Haki and overpower Lina’s will, turning her into a loyal ally. Lina revealed CP5’s plan to keep the Flower Country in civil strife, while Sun Keiyun decided to retrieve his gun and preserve his legal identity.

• Yitian Keiyun uploaded secret manuals to the Chat Group after befriending Yang Zhao and meeting his four-year-old daughter, Yang Xi, the Yellow-Clad Woman.

• Lina told Sun Keiyun that CP5 planned to support General Cai after the king’s death and provoke a war that would keep the Flower Country in civil strife.
• Sun Keiyun refused to leave without a legal identity and told Lina to help him retrieve his gun.

Sun Keiyun reclaimed his gun and convinced Li Huai not to give its technology to the World Government, arguing that mass-produced firearms could undermine the CP Organization and destabilize the government’s rule. After Lina arranged his upcoming schedule, Sun Keiyun chose to secretly visit Ohara as a prospector, leaving him curious about whether his Observation Haki might awaken a special trait.

• Li Huai returned Sun Keiyun’s gun, but first asked about how it worked and whether its technology could earn him merit.
• Sun Keiyun argued that the World Government’s widespread use of the gun could make CP5 redundant, invite political backlash, and strengthen other nations and Pirate Crews.
• Li Huai gave the gun back and ordered Lina to teach Sun Keiyun etiquette, then privately considered whether technology could put CP5 out of work.
• Lina told Sun Keiyun he would verify his identity at the Imperial Clan Office the next day and be formally introduced to the people in forty-two days.
• Sun Keiyun chose to travel secretly to Ohara disguised as a prospector, and Lina postponed his schedule by five days so he could make the trip.
• As they headed to his residence, Sun Keiyun wondered whether his Observation Haki could awaken a unique trait of its own.

Sun Keiyun left his temporary estate with Lina and boarded a prospecting ship bound for Ohara, disguising himself as a mute, impoverished man named Tim Cook. The ship’s crew mistook him for a potential recruit and planned to take him to Donquixote Doflamingo, leaving Sun Keiyun eager to meet him.

• Sun Keiyun toured the lavish estate Lina had arranged and resolved to contact Dragon after judging Flower Country’s nobles corrupt and careless.
• Lina woke Sun Keiyun and helped him sneak past the estate’s guards to reach a prospecting ship headed for Ohara.
• Sun Keiyun disguised himself as a destitute middle-aged man and used sign language to pass the ship’s crew’s questions as Tim Cook.
• The gangplank guard and a blond Tete family manager tried to recruit Sun Keiyun, then gave him a private room aboard the ship.
• The manager said he would ask the young master about Sun Keiyun, and Sun Keiyun realized he might meet Donquixote Doflamingo.

Sun Keiyun settled aboard Tete’s ship and discovered his Observation Haki could survey everything within nearly two kilometers. After seeing the gold prospectors’ dire condition, he resolved to remember the injustice without exposing his cover, then met Donquixote Doflamingo over a Den Den Mushi call.

• Tete gave Sun Keiyun a cramped hammock room and allowed him to go anywhere except the crew’s rooms and restricted decks.
• As Sun Keiyun slept, his subconscious refined its control by killing fleas and mosquitoes with increasingly precise bursts of force.
• Sun Keiyun woke at sea, awakened his unusual Observation Haki, and surveyed the ship and its four hundred gold prospectors.
• Sun Keiyun found dozens of prospectors near death from hunger and malnutrition, but restrained himself from intervening to protect his plans.
• Tete called Donquixote Doflamingo, who questioned the frail-looking Tim and ordered someone to bring Violet.

Doflamingo questioned Sun Keiyun, a mute gold prospector, about his origins and a West Blue assassination job, then grew impressed after learning Sun Keiyun had defeated Tete and was motivated by gratitude for three steamed buns. Sun Keiyun named Ryokugyu as his target, and Doflamingo promised to find him and recruit Sun Keiyun while supporting the sick gold prospectors aboard the ship.

• Doflamingo asked Violetta to read Sun Keiyun's thoughts, but she explained she could not use her ability through a Den Den Mushi, so Tete translated Sun Keiyun's gestures.
• Tete relayed that Sun Keiyun had forgotten his origins and was seeking someone he had been hired to kill, while Sun Keiyun concealed who had hired him and said the payment was three steamed buns.
• Doflamingo ordered Tete to fight Sun Keiyun, then learned that Sun Keiyun had defeated Tete in one move.
• After hearing that Sun Keiyun had accepted the job out of gratitude to someone who gave him their only food, Doflamingo offered to help him find his target in exchange for joining the Donquixote Family.
• Sun Keiyun wrote Ryokugyu's name on a board, and Doflamingo agreed to find and capture him while arranging food and medical care for the gold prospectors.
• Sun Keiyun revealed that he knew medical skills, and Doflamingo rewarded Tete with a promotion and told Violetta to ensure the Family welcomed promising fighters.

After reaching Ohara, Sun Keiyun discovered that the Tree of Knowledge had traces of a Spirit Tree and let Xingchen absorb its lingering Wood Qi. Xingchen’s power repeatedly ruptured and repaired Sun Keiyun’s meridians, leaving him unconscious as it prepared to help him retrieve the books from Paz Lake.

• Sun Keiyun left the Donquixote Family ship at Ohara, then traveled to Paz Lake beside the fallen Tree of Knowledge.
• Sun Keiyun found that Paz Lake was extraordinarily deep and asked Xingchen for help retrieving the books at its bottom.
• Xingchen sensed abundant Wood Qi around the Tree of Knowledge and explained that the tree’s growth had been interrupted after someone hollowed it out from within.
• Sun Keiyun placed his hand on the tree root, and Xingchen began absorbing its Wood Qi to gain the power to retrieve the books.
• Xingchen sent surging energy through Sun Keiyun’s meridians, repeatedly rupturing and repairing them until Sun Keiyun passed out.
• Xingchen realized that Ohara and the One Piece world’s unusual trees could help it grow far beyond its previous limits.

After absorbing the Tree of Knowledge’s Wood Qi, Sun Keiyun awakened powerful green Armament Haki that could heal wounds, then returned to the gold-panning ship and told Tete he had found a Devil Fruit. The Keiyun counterparts discussed power, governance, and the possibility that Daoist ideas could inspire a new path to artificial intelligence, while Yitian Keiyun remained in the Ancient Tomb.

• Sun Keiyun awoke with heightened senses and discovered his Armament Haki could cover half his body and rapidly heal his wounds.
• Sun Keiyun found the Tree of Knowledge withered after he absorbed its Wood Qi, then returned to the ship and healed Tete’s arm.
• Sun Keiyun told Tete he had found a Devil Fruit and learned that Tete had cut the gold-panners’ work short to avoid delaying him.
• Sun Keiyun asked True Person Keiyun how he resisted the temptations of power, and True Person Keiyun described using Haotian to monitor the ninja world.
• Biochemical Keiyun described plans to use Red Queen to oversee a future society, while Yitian Keiyun asked for advice on governing a country he had not yet begun to conquer.
• True Person Keiyun proposed linking Daoist thought with science, prompting the Keiyun counterparts to consider whether Yin Yang Bagua could lead to a different form of artificial intelligence.

Yitian Keiyun resolved to use Taoist principles to develop a new path of computer science that might help True Person Keiyun overcome his cognitive bias. Meanwhile, Pirate Keiyun recovered the Tree of Knowledge’s scanned collection, but its books contained no natural science; Sun Keiyun began organizing them and considered other sources of lost knowledge in the One Piece World.

• True Person Keiyun explained that his binary-based thinking limited his attempts to deduce laws and asked Yitian Keiyun to guide Taoists toward studying nature through the Five Elements, Yin Yang, and Bagua.
• Yitian Keiyun accepted the challenge, and True Person Keiyun encouraged him that perspectives from another world might help break his cognitive bias.
• True Person Keiyun asked Pirate Keiyun about the books from Ohara, and Pirate Keiyun had Xingchen confirm that it had scanned the Tree of Knowledge’s collection.

Sun Keiyun left Tete’s ship after telling him to stop the low-paying gold prospector business and arranging to speak with Donquixote Doflamingo. He reaffirmed their deal to find Ryokugyu, then proposed replacing the Donquixote Family’s low-margin crimes with a more profitable business, leaving Doflamingo intrigued by his mention of milk tea.

• Sun Keiyun told Tete that the gold prospector trips earned too little to support the crew and asked him to call Donquixote Doflamingo.
• Sun Keiyun assured Doflamingo that their agreement to find Ryokugyu and join the Donquixote Family still stood.
• Doflamingo welcomed Sun Keiyun, recognizing the value of his healing ability and Devil Fruit powers.
• Sun Keiyun explained that weapon smuggling and human trafficking produced limited profits after costs, bribes, and agents’ fees.
• Sun Keiyun offered to cooperate with Doflamingo using his knowledge of highly profitable businesses, then asked whether Doflamingo had heard of milk tea.

Sun Keiyun persuaded Doflamingo to test milk tea as a profitable business, and Doflamingo decided the Donquixote Family should transform and leave its criminal ventures behind. His plans stalled when Marines Vice Admiral Akainu arrived with a summons threatening Doflamingo’s Seven Warlords title.

• Sun Keiyun explained how milk tea could be produced cheaply and sold at high prices, then taught Doflamingo how to make it.
• Doflamingo tested the drink with Diamante, Violetta, and other people, discovering that women valued it far more than men did.
• Doflamingo concluded that milk tea could dominate a vast market and earn more than arms dealing or human trafficking, so he called a meeting to transform the Donquixote Family.
• A servant reported that Marines Vice Admiral Akainu’s warship was approaching Dressrosa’s harbor.
• Doflamingo learned that refusing the Seven Warlords Summons could cost him his title.

• Sun Keiyun entered Liu Xu’s secluded residence alone and openly told him he had been chosen by CP to infiltrate the Marines.

• Sun Keiyun listed Flower Country as his birthplace and said he rejected the Eighth Treasures Navy because it had become a source of turmoil.
• Sofan registered Sun Keiyun and told him to board the recruit ship, which would leave for Marine Headquarters that afternoon.

Sun Keiyun used his Observation Haki and the Great Soul Shifting Technique to slip unnoticed from a transport into Marine Headquarters, where he joined a wager duel with Boshu. He defeated Boshu with one blow, drawing the attention of the nearby Marines.

• Sun Keiyun planted the thought of ignoring him in a recruit's mind, then used his altered Observation Haki to move unseen through the transport and into Marine Headquarters.
