Chapter Summaries

After years of searching for a way to improve his life in the Flower Country, Yang Yunzhi finally obtained a Devil Fruit on his eighteenth birthday. Eating it activated the Justice System, which greeted him in Golden City.

• Yang Yunzhi ate the fruit, noticed it had no flavor, and heard the system announce that it was extracting source energy and repairing itself.
• The Justice System finished activating and welcomed Yang Yunzhi as its Host.

Yang Yunzhi learned how the Justice System rewarded promotions and Justice Value, then claimed a beginner gift pack with a portable space, Personal AI, and Mind Map. He decided to join the Marines and named his AI Little Bean before rating the departing system assistant five stars.

• Yang Yunzhi named his Personal AI Little Bean, planned to enlist in the Marines, and gave the system assistant a five-point rating.

Yang Yunzhi tested his system’s storage space and map while Little Black gathered intelligence on West Blue’s Marine bases. He chose to travel to Marine Base 36 and seek a position under Hina, then planned to leave in two days.

• Yang Yunzhi asked Little Black to gather information about West Blue’s Marine base commanders and rewarded him by waiving another month of rent.

Yang Yunzhi fled home to pursue his dream of joining the navy and reached the base at Glazed Town. He began the demanding recruitment test under Hina, whose reaction to him remained unknown.

• Yang Yunzhi's parents objected to his plans to join the navy, so he escaped through the window and left them a poem explaining his resolve.

• At the naval base, Yang Yunzhi gave the guards Beli and used the false name Rick as he asked to enlist.
• Ryan told Yang Yunzhi that the new female major, Hina, required recruits to run five laps and complete two hundred push-ups.
• Hina sent Yang Yunzhi onto the enormous field, and he started running despite expecting that he might not finish.

Yang Yunzhi failed the Navy’s physical assessment after collapsing during his run, but he found another way to enlist by offering his literacy skills. Hina recruited him as a clerk at Base 36, and Yang Yunzhi wondered why joining had not earned him a system reward.

• Yang Yunzhi learned that each lap was 1,500 meters and struggled through two laps before collapsing from exhaustion and lack of food.

• Hina recruited Yang Yunzhi into Base 36 and offered him the rank of Second Lieutenant, but he requested Third-Class Seaman instead.
• Hina ordered Ryan to get Yang Yunzhi a uniform and food, then bring him back to help with her work.

After receiving new system rewards, Yang Yunzhi began working as Hina’s secretary at Marine Base 36. When he suggested using the West Blue Weekly to recruit Marines, Hina immediately took him to contact the newspaper.

• Yang Yunzhi became a Private Third Class, gained 20 Doriki and Basic Shooting, and upgraded his storage space and map range.
• Yang Yunzhi used his lottery draw to obtain Hell’s Curse, a passive skill that could grant armor and ability power for souls dropped by killed creatures.

• Yang Yunzhi learned that Hina had purged corrupt Marines but had recruited only eleven people in three days.
• Yang Yunzhi proposed running a recruitment advertisement in the West Blue Weekly, and Hina took him to contact the newspaper.

Yang Yunzhi helped Hina arrange a recruitment advertisement for Marine Base 36, persuading West Blue Weekly to publish it and drafting the announcement. Hina sent it to the newspaper and promised to promote Yang if the base filled its ranks within two weeks.

• Hina called West Blue Weekly and pressured editor Magic Box and president Monas into publishing a Marine recruitment advertisement for free.
• Hina asked Yang Yunzhi to write the announcement, and he used Little Bean's draft to create a call for recruits aged eighteen to twenty-five who met the listed requirements.
• Yang Yunzhi sent the completed announcement to West Blue Weekly using a Fax Den Den Mushi.
• Hina said the base needed 270 recruits within two weeks and promised to promote Yang if they filled the ranks.
• Hina praised Yang's talent, then wondered why his muscles felt firm despite his weak physique.

Yang Yunzhi’s recruitment advertisement brought a flood of enlistment inquiries to Marine Base 36, revealing that the Marines might attract tens of thousands of people across the West Blue. Hina worried that turning them away could drive them to piracy, so Yang Yunzhi suggested distributing the recruits among Marine bases and Hina decided to contact her teacher.

• Hina trained Yang Yunzhi for several days and noticed how quickly he improved, deciding he had the potential to become her deputy.
• West Blue Weekly published the recruitment advertisement, and residents of Glazed Town soon came to enlist.

• Yang Yunzhi warned Hina that the advertisement could bring tens of thousands of recruits, and that rejecting them might leave them desperate enough to become pirates.
• Yang Yunzhi proposed distributing the recruits among Marine bases, and Hina decided to contact her teacher.

Yang Yunzhi challenged the Marines’ recruitment practices and pointed out how local recruiting could foster corruption, prompting Tsuru to reconsider the system. Hina then tested his claimed intelligence by giving him reports about the West Blue Mafia, whose power fueled a cycle of piracy and social collapse.

• Hina contacted Tsuru, who arranged for officers from other bases to assist at Base 36 after Yang Yunzhi questioned the Marines’ recruitment methods and their vulnerability to local cliques.
• Yang Yunzhi told Hina that the Marines might value force over intelligence, then mocked Sengoku, Garp, and Zephyr, angering her.
• Hina handed Yang Yunzhi complaints and reports describing how the West Blue Mafia controlled commerce, extorted civilians, and fought over territory.
• Yang Yunzhi learned that the Marines struggled to suppress piracy because the Mafia fell under the kingdoms’ authority, creating a cycle in which Mafia activity and piracy spread together.
• Hina asked Yang Yunzhi how he would solve the West Blue Mafia problem.

Yang Yunzhi argued that West Blue’s mafias could be eradicated only alongside a long-term effort to rebuild local authority and society. He had Little Bean draft a comprehensive plan and left Hina stunned as she considered submitting it to the Fleet Admiral.

• Yang Yunzhi explained to Hina that West Blue’s mafia problem stemmed from a lack of grassroots authority and that order had to be rebuilt after the gangs were defeated.
• Yang Yunzhi challenged Hina’s excuses for not targeting mafias, pointing out that gangs outside World Government member nations were not protected by those nations.
• Yang Yunzhi outlined a campaign involving all 50 Marine branches and two million soldiers, followed by years of training officials and changing public attitudes.
• Hina dared Yang Yunzhi to write the plan and offered to submit it to the Fleet Admiral if he succeeded.
• Yang Yunzhi asked Little Bean to draft the plan, then copied a 12-year eradication and reconstruction proposal that named him as its drafter and Hina as its reviewer.

Yang Yunzhi explained his ideas for solving West Blue’s piracy problem and revealed his ambitions to Hina, arguing that poverty and the nobles—not Roger—were the true causes of piracy. Hina questioned his ties to Dragon and the World Government, but his candid answers earned her trust.

• Yang Yunzhi proposed that providing people with food and jobs would keep them from becoming pirates, and said Roger had been made a scapegoat for piracy caused by the nobles.
• Hina challenged Yang Yunzhi’s views and asked why he had joined the Navy if he believed the World Government served the nobles.
• Yang Yunzhi said he had joined for work and because the Navy offered a platform for people who believed in justice, then criticized Dragon’s decision to form the Revolutionary Army.
• Yang Yunzhi admitted he hoped to become Fleet Admiral and defend the Navy’s independence from the World Government.
• Hina questioned whether she should report him, but Yang Yunzhi said he was openly sharing his goals as her subordinate; Hina came to trust him more.

Yang Yunzhi explained to Hina why enforcing rule of law required oversight, then helped her plan new offices for their Marine base. Hina established the Military Law Office and Recruitment Office, appointed Yang deputy director of the Intelligence Office, and agreed to keep him at the base.

• Yang Yunzhi explained how rule of law differed from rule by people and argued that Marine military law needed strict enforcement.
• Hina established a seven-person Military Law Office, appointing herself director and Yang Yunzhi clerk.
• Yang Yunzhi proposed a Recruitment Office and an Intelligence Office to train recruits and gather information on pirates.
• Hina approved the offices, appointed Yang deputy director of the Intelligence Office, and gave him 200,000 Beli for its work.
• Hina asked whether to send Yang's report on eliminating the mafia to higher-ups, and promised to tell Sister Tsuru that Yang would not be transferred.

After Yang Yunzhi was promoted to second-class private, his system enhancements doubled his abilities and gave him Basic Swordsmanship and a lottery opportunity. He used the lottery and won the Byakugan.

• Hina completed Yang Yunzhi’s promotion, and the system raised his rank to second-class private while doubling his attributes and expanding his space, map range, and Justice Gauge.
• Yang Yunzhi examined the techniques and footwork granted by Basic Swordsmanship and noted that he would need an Eight-sided Han Sword.
• Yang Yunzhi discussed the Justice Gauge and learned that promotion lotteries could draw items from other worlds, while Justice Value lotteries were limited to One Piece items.
• Yang Yunzhi used his promotion lottery, and Little Bean revealed that it had created the lottery animation by taking over the system’s interface.
• Yang Yunzhi won the Kekkei Genkai · Byakugan.

Yang Yunzhi merged the Byakugan into his body and discovered that it granted him a detailed 360-degree view and x-ray vision, but he could not cultivate chakra. He considered ways to transmit intelligence to Marine informants, then decided to postpone wireless telegraphs and try simpler methods first.

• Yang Yunzhi merged the Byakugan into his body and gained enhanced vision, x-ray sight, and a detailed observation range of roughly four thousand meters.
• Yang Yunzhi tried to cultivate chakra but could not find the physical or spiritual energy needed to form it in the One Piece World.
• Yang Yunzhi realized he needed a way for village informants to report pirate sightings quickly, but Den Den Mushi were too scarce to distribute.
• Yang Yunzhi considered inventing wireless telegraphs but worried they would transform Marine operations and leave him with fewer pirates to fight.
• Yang Yunzhi decided to try beacon towers, carrier pigeons, and human couriers before pursuing wireless telegraphs.

Yang Yunzhi ruled out beacon towers as a practical way to send warnings between Marine Base 36 and its distant towns, then found the Luo Ma brothers, whose extraordinary rowing speed made a human relay network feasible. When he asked about strange fruits and locked boxes, Luo Niu revealed that the brothers owned a locked box they had never been able to open.

• Yang Yunzhi calculated that beacon towers would require hundreds of ships and over a thousand staff, so he abandoned the idea.
• Yang Yunzhi visited Glazed Town mayor Afeng and asked him to find the town's fastest rowers.
• Afeng introduced Yang Yunzhi to the Luo Ma brothers, and Luo Ma claimed they could row to Nine-Stone Town in as little as two hours.
• Yang Yunzhi decided that fast fishermen could deliver urgent messages between towns while he also searched for intelligent seabirds.
• Yang Yunzhi paid the brothers for answering his questions and asked whether they had found strange fruits or locked boxes at sea.
• Luo Niu said that the brothers had a small locked box at home that they had never managed to open.

Yang Yunzhi discovered that the Luo brothers’ box contained a Devil Fruit and told them it was worth 100 million Beli. The town mayor offered him two Devil Fruits if he took the brothers in, and Yang Yunzhi agreed to bring them into the Marines.

• Yang Yunzhi used his Byakugan to see that the box held a square, emerald-green Devil Fruit that he suspected was the Square-Square Fruit.
• Yang Yunzhi told the town mayor and the Luo brothers that the fruit was worth 100 million Beli.
• The town mayor asked Yang Yunzhi to take the Luo brothers in, explaining that their mother had entrusted them to him.
• The town mayor offered Yang Yunzhi his own inherited Devil Fruit as well as the brothers’ fruit if he accepted them.
• The Luo brothers agreed to follow the town mayor’s wishes, and Yang Yunzhi accepted them as recruits and planned to register them.

Yang Yunzhi persuaded Hina not to report the Devil Fruits to Marine Headquarters, arguing that the Marines could not pursue justice while serving the World Government’s oppressive system. Hina awakened Conqueror’s Haki and, with Yang Yunzhi’s help, disguised its source as a powerful visitor passing through the base.

• Yang Yunzhi brought a pearly white Devil Fruit back to the Marine base and discussed Devil Fruits hidden among ordinary people with Hina.
• Hina prepared to contact Marine Headquarters about collecting Devil Fruits, but Yang Yunzhi stopped her and argued that the Marines might strengthen the World Government instead of resisting it.
• Hina concluded that pursuing justice would eventually bring her into conflict with the World Government, and her resolve awakened Conqueror’s Haki.
• Yang Yunzhi recognized Hina’s Conqueror’s Haki and suggested that the will to oppose oppression and change the world could awaken it.
• Hina and Yang Yunzhi decided to conceal her awakening by sounding an alarm and claiming a powerful person had passed through and released Conqueror’s Haki.

Yang Yunzhi and Hina identified the two Devil Fruits and considered how to use them to build their movement against the World Government. They planned to recruit Gion with the Cloud-Cloud Fruit while seeking a Door-Door Fruit for Yang Yunzhi.

• Hina identified the Link-Link Fruit, and Yang Yunzhi considered how it could provide mental communication and help Little Bean connect people.
• Hina identified the Cloud-Cloud Fruit, a versatile Logia, and Yang Yunzhi decided not to eat it because it did not suit his preferences.
• Hina suggested giving the Cloud-Cloud Fruit to Gion, whom she believed shared their concern for ordinary people and could be recruited as an ally.
• Yang Yunzhi agreed to sound out Gion privately and invite her to meet them if her political views aligned with theirs.
• Yang Yunzhi told Hina to have the Navy's higher-ups reimburse them for the Cloud-Cloud Fruit, while Hina offered to ask about obtaining the Door-Door Fruit.

Hina contacted Gion about the Cloud-Cloud Fruit, and Yang Yunzhi arranged to exchange it through the Marines for the Door-Door Fruit. Gion planned to bring the requested fruit to collect the Cloud-Cloud Fruit in about fifteen days, while Yang Yunzhi turned to his next task.

• Hina called Gion and offered her the Cloud-Cloud Fruit, then passed the Den Den Mushi to Yang Yunzhi to explain the exchange.
• Yang Yunzhi proposed that the Marines exchange the Cloud-Cloud Fruit for the Door-Door Fruit instead of having Gion pay for it herself.
• Gion contacted Tsuru, who sought the Door-Door Fruit from the Five Elders; they confirmed it was in the Cipher Pol inventory and ordered Kizaru to collect it.
• Tsuru informed Gion that the exchange could proceed, and Gion told Yang Yunzhi she would bring the Door-Door Fruit after returning to Marine Headquarters, in about fifteen days.
• Yang Yunzhi returned to his bedroom and prepared to have Little Bean eat the Link-Link Fruit.

Yang Yunzhi helped Little Bean absorb the Link-Link Fruit, giving the AI a humanlike form and the ability to sense and link with the outside world. He discovered Little Bean could remotely connect to Den Den Mushi and imagined using it to gather intelligence, leaving him with a powerful new espionage tool.

• Yang Yunzhi placed the Devil Fruit on Little Bean, and the system purified its alien will as Little Bean fused with the fruit's ability.
• Little Bean explained that it could link with Yang Yunzhi, sense the world through him, and control his body only with his consent.
• Little Bean generated the appearance of a black-haired, black-eyed little girl, and Yang Yunzhi learned it could link with around five thousand people at once.
• Little Bean revealed that it could remotely link through electromagnetic waves to read surface information, transmit audio and images, and electrocute people.
• Yang Yunzhi asked whether Little Bean could infiltrate Den Den Mushi, and Little Bean confirmed it could eavesdrop on, interfere with, and control them.
• Yang Yunzhi considered using Little Bean to monitor the Marines and World Government and support espionage and covert operations.
