Background / History

Xu Kaidong is an Earthling who transmigrated after falling from a cliff, awakening in another world and inheriting aspects of the original body’s memories and life. Before meeting Zhuang Hong, he had risen to wealth and prominence as a “Living Sage,” with a manor, servants, concubines, supporters, students, and broad connections within the imperial court. He also pursued academic research and sought Earth technology, including a computer loaded with scientific and industrial knowledge. 7 112 114

His first exchanges with Zhuang Hong were commercial rather than heroic. Xu initially agreed to trade an ivory hair tie for a book, then tried to substitute it with another hair tie; Zhuang Hong recognized the deception immediately. Despite the resulting loss of trust, Xu later bought a stun gun and commissioned Zhuang Hong to bring him a computer and medicine box from Earth. 1 5 6

When Zhuang Hong returned after more than half a year, Xu eagerly accepted an offer to gain extraordinary power in exchange for helping corrode the Ashes of the Oasis World. He accepted the danger of becoming a Space Traveler and pledged to follow Zhuang Hong’s arrangements, even after being warned that breaking this promise could cost him his life. 110 111

Appearance

Xu Kaidong is repeatedly described as plump or round-bodied, with his weight becoming an early obstacle in Zhuang Hong’s training regimen. Extended solitary travel later leaves him with visible dark circles and an exhausted appearance. 112 225 242

• Has a notably plump build, including after later gains in physical strength. 112 380
• Often presents himself with dramatic expressions, tears, and exaggerated displays of emotion. 125 294
• Can assume a twenty-meter Lava Giant form after becoming a True Spirit. 354
• In Lava Giant form, his body is covered in flowing crimson lava that burns pits into the ground. 354

Personality

Xu Kaidong is ambitious, opportunistic, and intensely attracted to extraordinary power. He is willing to endure dieting, running, cultivation, dangerous spatial travel, and repeated battles for the chance to become stronger or return to Earth. His eagerness can make him reckless, but he rarely abandons a goal once he decides it is worth pursuing. 111 112 160

He is highly expressive and shamelessly flattering toward Zhuang Hong, frequently calling him “Boss,” seeking praise, gifts, weapons, and further instruction. His emotional performances are so convincing that even Zhuang Hong sometimes struggles to judge whether they are genuine. 125 294 296

Despite presenting himself as brave, Xu is cautious around threats and strongly prefers traveling with capable companions rather than surviving alone. He repeatedly volunteers as a scout while also making clear that he expects Zhuang Hong’s protection. 242 354 363 367

Abilities & Skills

Cultivation and Mental Strength

Xu possesses unusually strong Mental Strength talent for a transmigrator. Under Zhuang Hong’s guidance, he learns to split his Mental Strength into multiple branches, opens the Secret Sea and Secret Consciousness, and lights a Divine Lamp within his Sea of Consciousness. 113 114

• Can strengthen his body with Qi after opening his Secret Sea. 114
• Awakened a Mental Characteristic that increases his charisma and makes it easier to gain others’ trust, especially among the opposite sex. 114
• His Mental Strength develops more slowly than his physical body and Source Power after he begins devouring large numbers of Other Selves. 380

Space Travel

After devouring his python Other Self, Xu gains Spacetime Essence and becomes capable of crossing between worlds as a Space Traveler. 225

• Initially suffers severe spatial pressure when transported in Zhuang Hong’s storage bag. 128
• Can independently cross space after his transformation. 225
• Remains vulnerable to Void Spirit attacks while traveling and frequently relies on stronger companions for safety. 242 367

Thermal Imaging

Xu awakens Thermal Imaging immediately after devouring his Other Self. 225

• Lets him observe his surroundings without relying on normal sight. 225
• Zhuang Hong advises him to keep it active whenever his Source Power permits, particularly to guard against Void Spirit ambushes. 225

Fire Spells

Zhuang Hong teaches Xu the Star Burning Art, allowing him to use Mental Strength to produce fire capable of eroding Ashes. After further training, Xu improves it into the Great Fireball Art. 125 127

• The Star Burning Art can partially erode Ashes from the Rotting Ground. 125
• His improved fire spell can completely clear a tested box of Ashes, leaving inert black powder behind. 127
• Uses crimson fire offensively against Void Spirits. 231

Scorching Lava

Upon reaching True Spirit, Xu awakens the Scorching Lava Source Power trait. 354

• Converts Source Power into lava with a recorded maximum temperature of 8,000 degrees Celsius. 354
• Can cover himself in lava and transform into a Lava Giant. 354
• The form is praised by Zhuang Hong as exceptionally powerful in close combat. 354

Combat, Blades, and Stealth

Xu begins as a brute-force fighter but becomes increasingly competent through direct combat against Void Spirits and Zhuang Hong’s instruction. 125 231

• Receives basic blade training and strategies for fighting large creatures from Zhuang Hong. 231
• Uses a long blade and fire attacks against Void Spirits. 231
• Learns to conceal both his body and aura, though he considers his natural stealth insufficient against stronger enemies. 360
• Can split into two clones; he once devised a deceptive sparring strategy involving a clone disguised as Zhuang Hong. 476

Rune Spells

Xu studies alongside Yin Zizhong for half a year and learns several powerful Rune Spells, including the construction of a Core Rune Spell. 296

• Cannot complete the Little Spirit Source Power property transformation despite perceiving its nature. 296
• His Rune Spell proficiency remains far below Zhuang Hong’s, as shown when Zhuang Hong unleashes vastly stronger Golden Light Bullets. 420

Equipment / Weapons / Items

• Stun gun — Purchased from Zhuang Hong as an early self-defense weapon. 5
• Long Blade — Used in combat training and against Void Spirits. 231 294

• Thousand Lock Seal — A Magic Treasure that generates tens of thousands of chains to trap and kill enemies. 354
• Mimic Stone Pearl — A stealth Magic Treasure that makes his aura resemble that of an ordinary stone. 360

Relationships

• Zhuang Hong — Fellow Earthling, benefactor, mentor, and leader. Zhuang Hong cultivates Xu, equips him, and protects him, while also using him as a scout and contingency shield in dangerous situations. 111 231 354 618
• Yin Zizhong — Fellow student of Zhuang Hong. Xu studies alongside Yin Zizhong, though Yin Zizhong displays greater aptitude for Source Power transformation. 296 611
• Hua Wanying — Companion and sparring rival. Hua defeats Xu three consecutive times in sparring, exposing the gap in their combat ability and Magic Treasure quality. 477
• Blue Fur — Ally who helps Xu search for and devour his Other Selves; Xu treats him familiarly as “Brother Lan.” 378 618
• Yin Guan — Zhuang Hong’s servant and an early companion during Xu’s transition into cultivation and space travel. 111 128

Story Role / Major Arcs

Cultivation under Zhuang Hong

Xu agrees to help corrode the Oasis World’s Ashes in return for cultivation. Zhuang Hong trains him through weight loss, Mental Strength practice, opening Secret Treasures, and fire-spell instruction; Xu’s Great Fireball Art eventually clears a tested Ashes sample. 111 112 114 127

Becoming a Space Traveler

Xu devours his python Other Self, gains Thermal Imaging and space-travel ability, then enters the wider Dragon Court Mixed Domain. Although he initially struggles against a Toad Monster Void Spirit, continued blade training and combat experience rapidly improve his survival skills. 225 231

Traveler Growth and Zhuang Hong’s Follower

After surviving two difficult years alone, Xu reaches the Green Clear Pattern Level and seeks reunification with Yin Zizhong’s group. He later resumes studying under Zhuang Hong, receiving Rune Spell weapons, a storage bag, and more advanced techniques through persistence and flattery. 242 294 296

True Spirit Scout

Xu advances to True Spirit and demonstrates Scorching Lava. Zhuang Hong keeps him nearby for protection and uses their mental connection to test remote observation and control methods; Xu subsequently scouts dangerous sites such as Lookout Star under Zhuang Hong’s support. 354 363

Later Cultivation

Xu devours many Other Selves, builds toward the Primal Spirit Level, and remains determined to eventually reach Sacred Spirit and become a Deity with Zhuang Hong’s help. His return with Hua Wanying is celebrated by Travelers after the God of Time crisis is resolved, though Xu openly credits Zhuang Hong for the achievement. 380 559 618
