Chapter Summaries

Lu Yuan entered Nuoding City with little money and explored its unequal districts while searching for affordable knowledge and lodging. The next day, he found the public library barred to him, endured mockery from academy students, and left as a thoughtful young woman watched him go.

• Lu Yuan passed the city guards’ inspection and entered Nuoding City with his bundle and seventeen Copper Soul Coins.
• He explored the wealthy main road and poorer side street, but could not afford books he wanted to study.
• Lu Yuan paid four Copper Soul Coins for a shared sleeping platform and recorded his observations and remaining thirteen coins in his notes.
• The next afternoon, Lu Yuan found that the public library required proof of Soul Master rank or an academy recommendation, neither of which he had.
• Three academy boys mocked Lu Yuan and one deliberately bumped his shoulder as they passed; he stayed quiet and left.
• A young woman carrying old books watched Lu Yuan leave, then studied a manuscript about abnormal low-level Soul Power circulation.

Lu Yuan gained entry to the library with Shen Moxin’s help and researched Soul Power, Martial Soul mutations, and Soul Beast ecology. While examining discarded research notes, he identified a flaw in an energy-decay model, leaving Shen Moxin astonished by his knowledge.

• Shen Moxin remembered Lu Yuan’s unusual behavior and later found him observing the library from an alley.
• Lu Yuan told Shen Moxin he wanted to research Soul Power theory, Martial Soul mutations, and low-level Soul Beasts, and she brought him inside under her responsibility.
• Lu Yuan rapidly reviewed basic Soul Power texts and recorded observations about mutation cases and Soul Beast habits.
• Shen Moxin secretly watched Lu Yuan’s focused research and noted his unusual behavior in her notebook.
• Lu Yuan found a fragmentary manuscript on Martial Soul energy fluctuations and concluded that its decay model wrongly treated the decay constant as fixed.
• Shen Moxin overheard Lu Yuan’s analysis and was genuinely astonished.

Lu Yuan explained to Shen Moxin how fluctuations in ambient Soul Power could alter Martial Soul energy decay, and she recognized the model’s potential. Their discussion ended when the librarian ordered Shen Moxin to meet the head librarian, while Lu Yuan slipped out through a side door.

• Lu Yuan described a model in which ambient Soul Power fluctuations changed the decay constant of released Martial Soul energy.
• Shen Moxin questioned Lu Yuan about how to measure the interference factor and coupling coefficient, then considered how his approach could affect other Soul Master assessments.
• The librarian ended Lu Yuan’s time in the restricted research area and warned Shen Moxin that she had brought in an unauthorized visitor.
• Shen Moxin took responsibility for Lu Yuan’s visit and told him to leave through the side door.
• Shen Moxin asked who had taught Lu Yuan his ideas, but the librarian returned and summoned her to see the head librarian immediately.
• Lu Yuan left through the side door, while Shen Moxin remained unsettled by his model and unusual knowledge.

Ning Zhishou reprimanded Shen Moxin for bringing Lu Yuan into the library, warning that the incident could hurt her upcoming evaluation. Shen Moxin secretly gave Lu Yuan notes, a map, and an address to meet her, and he left the academy for the old city.

• Ning Zhishou confronted Shen Moxin about letting Lu Yuan consult materials in the library’s inner section and warned her to follow the rules.
• Ning Zhishou reminded Shen Moxin that her teaching assistant evaluation was approaching and that her controversial course proposal had already damaged her standing.
• Lu Yuan left the library and spotted academy duty staff watching the entrance, so he hurried toward the academy’s outer fence.
• Shen Moxin caught up with Lu Yuan and told him to leave the grounds and avoid the library for now.
• Shen Moxin gave Lu Yuan handwritten notes, a map, and an address where he could meet her the next afternoon.
• Lu Yuan read her warning, then left the academy and headed toward the old city.

Lu Yuan and Shen Moxin explored theories about Soul Power and Martial Souls, with Shen Moxin realizing their ideas might help explain and even guide mutations. After hours of discussion, she invited Lu Yuan to enroll at Nuoding Junior Soul Master Academy as a work-study student, giving him a way to stay in the city and continue their research.

• Lu Yuan explained that his ideas about Soul Power’s environmental effects came from observation, then challenged Shen Moxin to consider what Soul Power really was.
• Lu Yuan proposed that Soul Power could behave as both particles and waves and described Martial Souls as intertwined structures of matter, energy, and spirit.
• Shen Moxin connected the theory to beneficial and harmful Martial Soul mutations and suggested that environmental Soul Power might shape Martial Soul structures during awakening or cultivation.
• Lu Yuan and Shen Moxin spent hours sketching their theories and discussing possible tests, recognizing each other as fellow researchers.
• Shen Moxin invited Lu Yuan to enroll at Nuoding Junior Soul Master Academy as a work-study student so he could remain in Nuoding City and access basic education and facilities.

Lu Yuan enrolled as a working student at Nuoding Academy, recorded and critically annotated a lecture on Soul Power, and discovered Wang Shuo being bullied over his allowance. The chapter ended with Lu Yuan stepping out of the shadows to intervene.

• Shen Moxin signed Lu Yuan's working-student application and told him to report to the academy office with his certificate.
• Lu Yuan received a place in Room C, met his roommate Wang Shuo, and recorded details about his living conditions and new acquaintance.
• During Lecturer Wu's evening lesson, Lu Yuan took careful notes and added his own critiques of the standard Soul Power method.
• Lu Yuan lent his notes to Wang Shuo, who went to collect his allowance after class.
• Three regular students cornered Wang Shuo behind the warehouse and took his pouch of Copper Soul Coins.
• Lu Yuan assessed the discarded objects nearby, then stepped out of the shadows.

Lu Yuan rescued Wang Shuo from three students trying to take his Copper Soul Coins, then used an old Soul Guidance Recorder to prove what had happened to the stewards. The students were punished, while Lu Yuan and Wang Shuo were ordered to clean the area, and Lu Yuan left wondering whether someone might remember the recorder.

• Lu Yuan used a burst of grain dust and Blue Silver Grass to disrupt the three students and make enough noise to summon the stewards.
• The freckled student accused Lu Yuan and Wang Shuo of starting the fight, but Lu Yuan pointed out an old Soul Guidance Recorder in the warehouse corner.
• The younger steward activated the recorder, which played fragments exposing the students' extortion and false accusations.
• The older steward docked the three students' allowances and assigned them a month of warehouse cleanup, while ordering Lu Yuan and Wang Shuo to tidy the area that day.
• After cleaning up, Lu Yuan told Wang Shuo he had guessed how the recorder worked, though he had actually recognized its design from his previous life, and the two returned to the academy.

Lu Yuan and Wang Shuo returned to their punishment work, where the deacons explained that the damaged recorder could no longer provide complete evidence and ended the dispute with a warning. Lu Yuan examined the recorder and considered its possible use as he continued sorting parts.

• Lu Yuan warned Wang Shuo that Zhang Hao and the others might retaliate later and advised him to stay cautious.
• The young deacon told Lu Yuan and Wang Shuo that the recorder had stopped working again and asked about analyzing its residual Soul Power traces.
• Lu Yuan explained how the traces might be analyzed and suggested a way to stimulate the recorder's sensitive nodes while warning that its data would remain incomplete.
• The young deacon said the academy could not punish Zhang Hao and the others without conclusive evidence, ended the matter, and warned both sides against further fighting.
• Lu Yuan examined the recorder's residual fluctuations and judged its design crude, then considered whether it could serve another purpose.

Wang Shuo brought Lu Yuan to Mo Chen’s scrap-filled workshop, where Lu Yuan recognized flaws in Mo Chen’s Soul Tool designs and proposed a simpler, more efficient circuit. Mo Chen realized the circuit could work and looked at Lu Yuan with renewed intensity, leaving their collaboration poised to begin.

• Wang Shuo took Lu Yuan to Mo Chen’s workshop and introduced him to the drunken, distrustful Soul Tool tinkerer.
• Lu Yuan identified the faulty connections in Mo Chen’s metal disc and explained the design flaws in a discarded Soul Power lamp core.
• Lu Yuan sketched improvements to the lamp core and described a simplified buffer circuit that could improve its efficiency.
• Mo Chen questioned Lu Yuan about the circuit’s parameters, and Lu Yuan claimed he had developed them through observation and trial and error.
• Mo Chen gave Lu Yuan a metal plate and asked him to draw the complete circuit, then declared that it would work.

Lu Yuan and Mo Chen tested Lu Yuan’s simplified Soul Power circuit by building a crude lamp, which shone brighter and more steadily than Mo Chen’s old design. Mo Chen recognized the circuit’s value and warned Lu Yuan that Spirit Hall’s technical department might imprison him to control it.

• Lu Yuan explained how the circuit’s curved channels and three-way split reduced energy loss and improved stability.
• Mo Chen etched Lu Yuan’s design onto a metal plate, filled its grooves with Soul Power adhesive, and assembled it with salvaged parts.
• Mo Chen injected Soul Power into the new lamp, which lit with a steady glow and grew more than thirty percent brighter than the old lamp.
• Mo Chen broke down after seeing the lamp work, then told Lu Yuan that Spirit Hall’s technical department might drag him back and lock him up for ten years.

Lu Yuan urged Mo Chen not to destroy his affordable Soul Power lamp design, but to hide his work and wait for an opportunity to challenge the monopoly on Soul Tool technology. Days later, Teacher Sun publicly condemned a work-study student for questioning a textbook circuit, while Lu Yuan continued sketching in secret.

• Mo Chen told Lu Yuan and Wang Shuo how the Spirit Hall Technical Department punished him for designing cheaper Soul Power lamps and forced him to abandon his work.
• Lu Yuan explained that Mo Chen's invention could help ordinary families, but powerful merchants and monopolies would try to suppress it.
• Lu Yuan encouraged Mo Chen to stay safe, keep developing his skills discreetly, and wait for an opportunity to spread the technology.
• A rumor spread through Nuoding Academy that Teacher Sun had torn up a work-study student's sketch proposing a simpler parallel circuit and scolded him in front of the class.
• Teacher Sun noticed Lu Yuan drawing circuit-like lines with a twig behind the library, but dismissed him as an overconfident child.

Lu Yuan challenged Teacher Sun’s lesson on the triangular buffer array, explaining its resonance risk and proposing a feedback node to improve it. After Teacher Sun ordered him to copy a textbook chapter, a quiet girl told Lu Yuan that an old family notebook described a similar device called the “Moonlight Stabilization Ring.”

• Lu Yuan identified a resonance flaw in the triangular buffer array Teacher Sun presented as a proven classic.
• Lu Yuan raised the risk in class and proposed adding a sensing node and reverse capacitor to disrupt dangerous fluctuations.
• Teacher Sun rejected the proposal, berated Lu Yuan, and ordered him to copy chapter three of the textbook ten times.
• After class, Lu Yuan wrote down his improved design while the other students left without speaking to him.
• A girl wearing a bracelet of dark brown seeds told Lu Yuan that an old family notebook described a similar device called the “Moonlight Stabilization Ring.”

Lu Yuan learned that Bai Zhi’s family Moonlight Ring method used the Moonlight Orchid’s gentle nourishment to stabilize energy, a principle related to his Soul Tool feedback-node theory. He enlisted Bai Zhi to help test the method, then learned that Teacher Sun might alert hostile interests at the Hundred Refinements Pavilion to his ideas.

• Bai Zhi showed Lu Yuan her great-grandmother’s notebook describing the Moonlight Ring method and its energy-stabilizing field.
• Lu Yuan recognized that the method’s self-regulating principles resembled his proposed Soul Tool feedback nodes.
• After reading the notebook, Lu Yuan explained the connection between the Moonlight Orchid’s natural properties and artificial circuits, and Bai Zhi agreed to help record data from her practice.
• Lu Yuan and Bai Zhi discussed the Moonlight Ring’s Soul Power use and stability, and he gave her a table for recording test results.
• Before leaving, Bai Zhi warned Lu Yuan that Teacher Sun was close to the proprietor of the Hundred Refinements Pavilion and might pass along his ideas.

Jin Rui investigated Lu Yuan’s Soul Tool ideas and his connection to Mo Chen, prompting Lu Yuan to recognize the Hundred Refinements Pavilion’s interest in their research. After persuading Mo Chen to continue developing his circuit, Lu Yuan returned to the academy and was summoned for questioning over a storeroom robbery.

• Jin Rui questioned Teacher Sun about Lu Yuan’s ideas and mentioned that a shop assistant would investigate around the academy.
• Mo Chen told Lu Yuan that a stranger had been asking about him and feared the Spirit Hall Technical Department was repeating its old surveillance tactics.
• Lu Yuan deduced that the Hundred Refinements Pavilion was probing their research and used a Moonlight Orchid stabilization design to convince Mo Chen not to destroy his sketches.
• Lu Yuan advised Mo Chen to hide his records and act as though he had stopped researching, while Lu Yuan planned to present himself as an ignorant student.
• When Lu Yuan and Wang Shuo returned to the academy, deacons accused Lu Yuan of being near the storeroom and ordered him to come to the deacons’ office for questioning about stolen Soul Beast materials.

Lu Yuan challenged the evidence against him by explaining how fluorescent powder could reveal the thief, and Shen Moxin helped secure an inspection. The examination cleared Lu Yuan and Wang Shuo while exposing fluorescent powder on Zhang Hao's clothes and shoes.

• Lu Yuan argued that fragments found under his bed had been planted and proposed checking everyone’s clothes and shoes for fluorescent powder.
• Shen Moxin arrived, supported Lu Yuan’s method, and persuaded the older deacon to examine the accusers as well.
• The deacons brought Zhang Hao, Li Wei, and Zhao Kun to a dark room for the inspection.
• The examination found no unusual fluorescence on Lu Yuan’s or Wang Shuo’s belongings.
• The older deacon discovered glowing powder on Zhang Hao’s cuff and shoe, and Zhang Hao blurted out that he had washed his hands.

Lu Yuan exposed Zhang Hao as the student who planted evidence to frame him, but the stolen materials and the masked sponsor remained unknown. Shen Moxin warned that the Hundred Refinements Pavilion might be behind the plot and that Lu Yuan could face a hostile annual assessment.

• Lu Yuan used fluorescent powder on Zhang Hao’s cuff and shoe to show that Zhang Hao had handled the stolen materials and planted the wrapping under Lu Yuan’s bed.
• Zhang Hao confessed that a masked person paid him five Gold Soul Coins to frame Lu Yuan, while denying knowledge of the stolen materials.
• The older deacon cleared Lu Yuan of the frame-up and said Zhang Hao would be disciplined, but noted that the actual theft remained unsolved.
• Shen Moxin warned Lu Yuan that the Hundred Refinements Pavilion might see his ideas as a threat and that a friend of Teacher Sun could target him during the annual assessment.
• Lu Yuan returned to the dormitory with Wang Shuo and decided he would take the assessment despite the risk of expulsion and reduced resources.

Lu Yuan’s unconventional answers earned him a disputed score, and Shen Moxin challenged Director Ning Zhishou’s decision to withhold it. After Lu Yuan said he had invented his method himself and offered to test it, Ning called an Assessment Committee meeting for the next morning.

• Lu Yuan saw that his ninety-seven-point theory score was marked for review, while students nearby accused him of cheating.
• Shen Moxin questioned Ning Zhishou in his office about why Lu Yuan’s answers had been rejected as improperly formatted.
• Ning explained that Lu Yuan’s notes and unfamiliar mathematical method seemed suspicious, while Shen defended their rigor.
• Lu Yuan told Ning he had devised the method himself and offered to verify its predictions through measurement.
• Ning agreed to convene the Assessment Committee the next morning and ordered Lu Yuan to explain where his ideas came from.

Lu Yuan defended his unconventional Soul Power calculations before the assessment committee and received 97 points on his theory assessment. Teacher Zhou invited him to help investigate Soul Beast sample decay, while Shen Moxin warned that Director Ning would watch him more closely.

• Lu Yuan explained his formulas for terrain slopes and Soul Power output, arguing that his methods could improve retreat speed by fifteen percent.
• Shen Moxin and Teacher Zhou supported Lu Yuan's reasoning, and Ning Zhishou ended the review by awarding him 97 points.
• Teacher Zhou invited Lu Yuan to visit his laboratory and examine his research into Soul Power decay in removed Soul Beast samples.
• Shen Moxin warned Lu Yuan that Director Ning would scrutinize him more closely, and Lu Yuan accepted the risk of working with Teacher Zhou.
• Lu Yuan left the meeting room and found Wang Shuo waiting anxiously at the edge of the training ground.

Lu Yuan investigated strange Soul Power fluctuations in low-level Soul Beast materials and earned access to Zhou Chun's laboratory. After learning that Wu Gang and a biased referee awaited him in the practical assessment, he considered the rules and quietly prepared for the confrontation.

• Wang Shuo told Lu Yuan that he had been matched against the powerful Wu Gang and that Instructor Chen would referee the assessment.
• Lu Yuan identified anomalies in eight years of material data, proposed experiments to Zhou Chun, and was given a laboratory key and a research assistant role.
• Lu Yuan tested Bristle Rat quills in different containers and found that their Soul Power fluctuations peaked regularly at midnight and noon.
• Wang Shuo urged Lu Yuan to avoid the assessment, but Lu Yuan gathered his research and confirmed the assessment was the morning after tomorrow.
• That night, Lu Yuan considered the Soul Power tides and the assessment rules, then clenched his fist as he resolved to face the challenge.

Lu Yuan prepared for his practical combat assessment against the stronger Wu Gang by studying his habits, the rules, and the platform while gathering low-level materials for a tactical plan. The match began with Wu Gang activating his Iron-Arm Ape Martial Soul, and Lu Yuan faced him as his final strategy came together.

• Wang Shuo warned Lu Yuan that Wu Gang was a powerful opponent and that Instructor Chen was likely to favor him, but Lu Yuan stayed calm.
• Shen Moxin gave Lu Yuan past assessment rulings and information about Wu Gang’s temper and fighting style, while Bai Zhi supplied herbs and noted Wu Gang’s shoulder movement before using a Soul Skill.
• Lu Yuan inspected the platform’s worn granite edges and studied how its features and the referee’s viewpoint could affect the assessment.
• Lu Yuan tested low-level Soul Beast materials and Blue Silver Grass, then worked out a tactical plan before the assessment day.
• Instructor Chen announced the rules, and Wu Gang and Lu Yuan began their match with Wu Gang activating his Iron-Arm Ape Martial Soul.
