Power Progression

Background / History

Earth’s Destruction and Captivity

Before Earth’s destruction, Leo exercised regularly and conducted business; he had just closed a two-million deal when the sky fractured. After the catastrophe, he was imprisoned with other Earth humans and watched captives disappear in daily selections. Determined to survive and find his family, he seized the safest corner of the cell and used weaker prisoners as shields 1 2.

Abigail eventually placed him on a sacrificial altar. As the ritual drained his vitality, a shadow enveloped him and restored his body with extraordinary strength. The power transmitted through the ritual’s spatial passage fundamentally changed him from an ordinary Earth human into a life-form capable of continued evolution 3 4 41.

Training at Purple Flame Academy

Purple Flame Academy placed Leo under Gru’s instruction, while the Purple Flame Stigmata Wizard took a concealed interest in his development. A consciousness within Leo offered to teach him bloodline control; Leo called it the “old grandpa” and kept its existence secret 5 6.

Leo became the academy’s unusual body-refinement apprentice in an institution devoted to elemental wizardry. He spent ten years at Jiafaqi’s tower, serving as a poison-test subject while studying and conducting experiments. Although the trials developed useful resistances, accumulated toxins badly damaged his body and left his overall strength stagnant 7 8 11.

Gru subsequently subjected him to tightly controlled beatings and gravity training. Leo combined this instruction with his own research into cellular adaptation, eventually adding electrical, thermal, and toxic stimulation to his regimen 15 35.

Apprentice Service and First Advancement

During his twenty-year garrison assignment, Leo helped select apprentices for Purple Flame Academy and developed a productive relationship with Tiyama City’s lord, Samatchi. He also hunted beasts to improve his combat instincts and unlock his physical potential through life-threatening encounters 29 35 37.

Alice accompanied and protected him during his apprentice years. Their tournament journey forced him to confront Abigail, whose mere presence revived his captivity trauma. Leo restrained his urge for revenge because Abigail still greatly outclassed him; he and Alice later survived an encirclement by thousands of apprentices 40 41 51.

After reaching the apprentice limit through nuclear-radiation-assisted evolution, Leo underwent a ten-year transformation into a Level One Hunter. He then brought Benji out of his consciousness under a Battle Partner Contract, securing control over the being who knew his secrets 55 57 60.

Hybrid Wizardry and Interworld Expeditions

Leo pursued elemental wizardry alongside body refinement, but progress demanded long periods of unsuccessful research. Forty years of experiments produced little immediate improvement beyond the passive benefits of his training arrays and radiation-assisted evolution 89.

In Black Tomb World, his reflection consumed part of his consciousness before returning and healing his soul. He later completed his Level One elemental advancement, gained Yaoyao as a soul companion, and developed increasingly efficient nuclear fission witchcraft 106 120 122.

Gru’s death devastated Leo. Alice recognized Gru as his irreplaceable guide—the teacher who had first made the unfamiliar Wizard World feel safe. Leo later learned that Alice had been investigating the murder rather than concealing the truth, repairing a serious misunderstanding between them 147 224.

Giant World, New Earth, and His Academy

In Giant World, Leo acted as an intermediary between the wizard army and the God of Giants, advanced to Level Two body refinement, and befriended Wakeda’s tribe. He taught the giants smelting, cooking, fishing, trapping, and basic writing, while also cultivating a lasting foothold among them 186 191 192 193.

After obtaining a First-Class Wizard Medal, he demanded information about Earth’s survivors from Green Cottage. Learning that the organization had gathered them on one planet and withheld knowledge of wizards enraged him 196.

Leo later treated New Earth as a source of talented recruits rather than a profit-making territory. His academy grew to more than thirty thousand apprentices, supported by hired teachers and resources from former Black Skull territory. Repeated disasters inflicted on him by New Earth’s World Consciousness eventually drove him back to the Wizard World 425 465 514.

Stigmata Ascension and the World Wars

Charlotte’s disclosure of a spatial rift nearly deprived Leo of an opportunity to advance to Stigmata. After confronting that betrayal and securing support from Undying Body, Leo organized his affairs and completed his Level Four ascension 490 492 501 504.

During the World Cluster War, Leo fought the Lords of Souls, created the independent soul clone Black Soluo, and developed close working relationships with Interstellar Wanderer and Heluoluo. He subsequently advanced to Level Five and obtained approval to lead his own world-war team 571 583 605 608 664.

His search for the Little Bookworms took him toward Dragon World and the Hundred-Page World. With Baturu and Black Soluo, he developed a three-headed, six-armed fusion form and pursued the shadows of universe-grade treasures through the Shadow World 752 773.

Break with the Wizard World

Leo’s relationship with the Wizard World collapsed amid political targeting, assassination attempts, and conflict over the Little Bookworms. After killing the Tower of Elements and the Eye of Destruction, he withdrew his forces and established himself in a demiplane outside Barbarian World 848 855 870.

Yaoyao relocated the young wizards to New Earth, moved the Gulu Beasts into the Shadow Plane, and removed the mothership’s tracking backdoor. Leo thereafter lived as a cosmic wanderer without a world whose will would bless him; the Wizard World Will actively regarded him as an enemy 855 896.

He evaded pursuing Supreme Lords through superior information and mobility, while waging a war intended in part to expose the Wizard World’s remaining reserves and Guardian Wizards. Bloodline Controller finally forced him to appear by threatening Alice’s soul 915 945 946.

Surrender and Supreme Lord Ascension

Leo surrendered in exchange for the promised return of Alice’s soul. He relinquished the Endless Pot and Eye of Destruction, entrusted his allies to Beast Blood Boiling and Undying Body, and accepted entry into the Land of Origin. The Supreme Lords partially healed him before restraining him and knocking him unconscious 946.

During his later ascension, Leo met the final remnant of his previous incarnation and learned that his existence extended beyond his current lifetime. After reaching Supreme Lord, he merged with his two soul avatars to attain Level Eight and announced that he would next demonstrate Level Nine; the supplied passage ends before that further advancement is shown 956 957 1007 1008.

In his latest documented battle, he effortlessly evaded the Emperor of Titans and the Insect Race Mother Nest’s coordinated attacks, stole Yalisi’s bronze crown, and struck him with the Godslaying Staff 1029.

Appearance

• Human form: Approximately 1.8 meters tall, with a muscular build developed through exercise. Black hair is restored when he abandons his Homo sapiens disguise 1 45 290.
• Apprentice combat state: Expands to roughly two meters as his muscles swell and his robe tightens around him 45.
• Hunter form: Initially reaches three meters, with dark, heavily knotted muscles and sharp nails; later reaches the four-meter limit of Level One body refinement 59 161.
• Homo sapiens disguise: Hairless head, elongated limbs, and six fingers 282.
• Vajra Giant form: A six-hundred-meter black metallic giant when combined with his Stigmata True Body 703.
• Soul-avatar fusion: Three heads and six arms, allowing him to wield several universe-grade treasures simultaneously 773 1007 1008.

Personality

Leo’s earliest defining trait is an extreme determination to survive. In captivity, he beats aside other prisoners and hides behind women, rationalizing his conduct through his desire to find his family. His fear of death remains so deeply rooted that it shapes his first bloodline transformation into the evasive, survival-oriented Hunter 1 2 57.

As a researcher, he is obsessive, skeptical, and methodical. He questions inherited knowledge, tests explanations against combat experience, and replaces meals with nutrient solution to save time. Even an intended holiday quickly becomes an opportunity to plan centuries of advancement 15 35 199.

He is calculating about both threats and relationships. Benji recognizes that Leo’s friendly negotiation conceals a willingness to kill him if he refuses a contract. Leo also maintains useful acquaintances, conceals his strength, and readily lowers his pride when dealing with stronger figures whose support he needs 60 123 144 492.

His ruthlessness coexists with strong personal attachments. He mourns Gru openly, cares about the survival and cultivation of his Gulu Beasts, and ultimately sacrifices his freedom for Alice’s soul. Despite his achievements, he remains homesick and admits that he would prefer his original Earth life to power without belonging 147 335 946 956.

Abilities & Skills

Adaptive Evolution and Body Refinement

Leo strengthens his body by forcing it to survive controlled stresses and replace vulnerable cells with better-adapted generations 15 23 35.

• Uses poison, gravity, electricity, heat, and cold to stimulate continued evolution 35 83.
• Develops resistance to deprivation, tougher skin, increased cellular energy storage, and substantial regenerative ability 23 35 434.
• Adapts to foreign-world conditions; in Jiefute World, he estimates that he can recover full combat effectiveness within three days 64.
• Can reshape his body within controlled limits, enabling his Homo sapiens infiltration 282.
• His tonsil modification permanently reduces maximum stamina by 5% and strength by 3% 513 661.

Elemental Body Refinement

His elemental and physical cultivation paths reinforce each other rather than functioning as separate specialties 120 122 238.

• A stronger physique supports greater mana capacity and higher spiritual power during advancement 120 122.
• Simultaneous advancement produces unusually high starting attributes 366 513 661.
• The hybrid attack bonus rises from 23% after his Level Two body-refinement advancement to 32% at Level Three, 43% at Level Four, and 60% at Level Five 186 514 661.
• Mana consumption remains a major constraint even after substantial increases in capacity 238.

Shadow Talent and Shadow Walking

Leo’s shadow functions as a controllable, semisolid extension of his body 5 6.

• Forms tentacles, handles weapons, operates Gatling guns, and stores supplies 6 18.
• Enables rapid movement between shadows and escape from ordinary physical restraints 16 315.
• Creates mobile attack platforms carrying inscribed rune arrays; at Level Two, shadows can appear anywhere within a 4,800-meter range 186.
• Ordinary shadow weapon strikes initially have low offensive power, testing at only half his strength attribute 65.
• His Hunter shadows bear damage for him. A later configuration absorbs 50% of incoming damage, subject to a finite capacity 57 271 285.

Shadow World and Shadow Space

With Yaoyao’s assistance, Leo uses the Shadow World for travel, infiltration, and access to otherwise unreachable objects 369 515 517.

• Crosses a spatial barrier that he cannot break directly, though emergence can be dangerous and physically destabilizing 369.
• Uses Shadow Space and shadow ropes to retrieve the Black Metal Module 515.
• Accumulates enough energy through nuclear fusion for Shadow Space to wield the Power of Laws 519.
• Expands the Shadow Plane and sends more than ten thousand shadows into the universe 773.
• Regards Shadow Space as a major means of challenging opponents above his own level 580.

Nuclear Fission and Fusion Witchcraft

Leo incorporates nuclear materials and reactions into both combat and cultivation 55 122.

• Radiation absorbed through shadows accelerates cellular evolution 55.
• Yaoyao’s shadow can contain nuclear material, allowing Leo to sense radiation and initiate controlled fission 122.
• At Level Two, fission of 0.7 grams of material at 40% efficiency produces a fully enhanced attack of 15,493 points 263.
• Masters controlled fusion during Level Four and later uses Tritium-Deuterium Fusion Great Witchcraft to kill three Level-Five Lords of Souls 519 703.
• Uses atomic bombs to delay pursuit and hydrogen bombs for city destruction and battlefield traps 231 571 605.
• Maximum-output fusion depends on his body-refinement strength; sealing that side prevents him from using his strongest output 651.

Lightning Witchcraft

Lightning is Leo’s principal conventional elemental specialty, supported by the affinity gained from a body transformed with the God of Giants’ blood 61 234.

• Modifies existing lightning witchcraft to suit his own physiology 234.
• Defeats a Level Three Dragon-Winged Giant wizard through repeated electrical attacks 479.
• His spell knowledge initially lags behind his physical growth. Even at higher levels, highly skilled spellcasters can exploit gaps in his technical repertoire 234 818.

Domains and Defensive Combat

Leo builds his combat system around weakening opponents while maintaining layered protection 263.

• Uses a combined witchcraft effect that opponents estimate can reduce their strength by over 60% 484.
• Deploys thirteen domains against Yaliso and crushes nearby mechs with his Gravity Domain 537.
• Combines physical toughness, Indestructible Body, the Godslaying Wizard Robe, giant-form armor, damage-bearing shadows, and regeneration 434.
• His defenses have limits: a single tree-branch attack exceeding 70,000 points fills a 32,000-point shadow absorption capacity despite other protective layers 285.

Bloodline Transformations

Soul Avatars and Powers of Laws

Leo develops independent soul avatars and incorporates their accumulated power into his own advancement 519 583 770.

• Black Soluo possesses an independent consciousness and a markedly more belligerent personality than Leo 583.
• Fusion with Baturu and Black Soluo creates his three-headed, six-armed combat form 773.
• Draws on microscopic atomic laws, the Black Metal Module’s metal laws, the Endless Pot’s soul laws, and laws gained through his avatars 770.
• Reintegrating both avatars raises his Supreme Lord combat form from Level Seven to Level Eight 1007.

Equipment / Weapons / Items

• Early short blades — Apprentice weapons used alongside shadow-controlled firearms. His initial low-end blade costs 100 wizard coins 6 18.
• Gru’s greatsword — Three-meter graduation gift; adds approximately 50 points to his early physical attack power 35 36.
• Thunder-forged stone spear — Six meters long and weighing one ton. Provides a 15% attack bonus, capped at 300 points, and a 25% lightning bonus, capped at 500 points; initially requires Hunter form to wield 61.
• Godslaying Staff — Enhances elemental attacks and Shadow Talent, changes length, stores energy for mana recovery, and serves as a heavy physical weapon. Its original physical bonus ranges from 1,000 to 20,000 points, depending on extension and Leo’s ability to bear its weight 131.
• Godslaying Wizard Robe — Major defensive and shadow-enhancement equipment. Its upgraded form provides 20,000 defense at his then-current strength, short-range Shadow World jumps, and three anchored travel locations within a world 434 465.
• Wizard Medals — His Third-Class Medal grants substantial command privileges; obtaining a First-Class Medal fulfills Green Cottage’s condition for releasing information about Earth’s humans 103 196.
• Fate Wizard Book — Displays his attributes and provides information, including warning of the planned blood sacrifices intended to locate him 513 917.
• Black Metal Module — Universe-grade, shape-changing black cube retrieved as Yaoyao’s thousand-year gift. Gives access to a second power of laws beyond Leo’s own microscopic-world laws 515 661.
• Endless Pot and Eye of Destruction — Universe-grade treasures he relinquishes to Beast Blood Boiling and Undying Body during his surrender. Both appear again with his later Supreme Lord fusion form 946 1008.
• Book of Origin, black longsword, and broken black saber — Among the seven universe-grade treasures displayed by his Level Eight fusion form 1008.

Relationships

• Alice — Protector, close friend, and eventual lover. Their relationship grows from her secret assignment to guard him; her soul later becomes the leverage used to force his surrender 79 235 946.
• Yaoyao — Soul companion and indispensable partner in shadow travel, nuclear-material handling, intelligence gathering, and treasure retrieval. Leo considers Yaoyao his strongest ability 120 122 369 517.
• Benji — Initially the hidden “old grandpa” offering bloodline guidance in exchange for help finding Liquid of Origin. Becomes Leo’s contracted battle partner and frequently carries, guards, and assists him 5 7 60 106.
• Gru — Body-refinement teacher and Leo’s most important early guide. His death leaves Leo grief-stricken and determined to pursue the truth 15 147 224.
• Jiafaqi — Experimenter and instructor whose tower houses Leo for ten years. The relationship combines severe poison trials with access to a laboratory and extensive knowledge 8 11.
• Purple Flame Stigmata Wizard — Powerful early patron who monitors Leo’s development and assigns Alice to protect him. Leo later seeks revenge against him 5 57 79 434.
• Abigail — The apprentice who placed Leo on the sacrificial altar. Becomes the focus of Leo’s trauma and hatred, only to find himself outclassed once Leo reaches Level Two 40 41 204.
• Samatchi — Tiyama City’s lord and a useful friend, trading partner, and source of experimental discussion 29 30 35.
• Nigel — Samatchi’s son, whom Leo allows to study at his side and assist with knowledge-related work 205 208.
• Wakeda — Giant friend and trading partner. Leo supports his tribe’s development while also seeking influence among the giants 191 193 196.

• Undying Body and Beast Blood Boiling — Senior supporters and long-term allies. Their friendship survives manipulation, political conflict, and a private challenge, though both become openly skeptical of Leo’s claims of innocence 492 775 946 971.
• Interstellar Wanderer and Heluoluo — Wartime allies who come to treat Level Four Leo as an equal and establish trade ties with his academy 571 608 664.
• Baturu and Black Soluo — Independent soul avatars and partners in his fused combat form 583 773 1007.
• Little Bookworms — Allies whose recovery and reunion become central to his later expeditions and conflict with the Wizard World. No. 007’s unexplained knowledge of Leo’s secrets also makes him wary 664 752 848 855.
• Bloodline Controller — Supreme Lord adversary who uses Alice’s soul to secure Leo’s surrender 945 946.
