Yan Beiyou

Biodata

Background / History

Yan Beiyou’s background was long unknown to the public. He lost his parents in a tsunami when he was two years old and was later raised on Morning Star, where the former Star Lord became an important teacher and protector in his life. 141

More than a decade before the main story, the former Star Lord—an SS-rank omega—was killed after influential families colluded with an invading civilization. Yan emerged at approximately sixteen and used his Black Dragon Companion Beast to eliminate the families responsible for the betrayal. At eighteen, he formally took control of the star system through overwhelming strength; fourteen years later, he remains its unquestioned ruler. 2 3 31 131

To stabilize his early rule, Yan cultivated an image as a cold-blooded, merciless emperor and rejected those who attempted to offer omegas to him. Once his position became secure, he acknowledged that he was not opposed to romance—he had simply never met anyone suitable. 3

Three years before the omega coming-of-age ceremony, Yan used his Black Dragon Companion Beast as the model for an unbeatable virtual-game boss. He noticed that the player Little Mushroom had accumulated an extraordinary number of challenge attempts and later took over the boss AI to speak with him directly. 2 5

Yan attended school on Morning Star and was known for both skipping class with Ji Yunqi and decisively defeating arrogant Dream Star heirs who looked down on Morning Star residents. 84 105 106

Appearance

Yan is a nearly two-meter-tall alpha with a powerful build and an imposing presence that contrasts with his restrained manner. 5 12

• Short black hair, often neatly combed back in formal settings. 30
• Deep, sharply defined, conventionally handsome features. 16 30
• Broad shoulders, narrow waist, and long legs. 12
• Deep black eyes described as tranquil, warm, and tolerant when he looks at Ye Nanxun. 15 35
• Wears austere black-and-gold imperial uniform within the palace; favors dark coats and simple knitwear in private. 12 30
• His civilian disguise technology can alter his facial appearance. 27 28
• During partial beastification, his hands develop black scales and claws, while his legs transform into an enormous black dragon tail; he can also develop dragon horns. 47 71
• He frequently uses masks or disguise technology while accompanying Ye in public to avoid immediate recognition. 84 90

Personality

Yan is publicly serious, meticulous, and difficult to approach. His immense authority causes even influential nobles and officials to treat him with reverence, while his long-standing lack of romantic experience makes him the subject of teasing among his three childhood friends. 3 13 35

In private, he is observant, patient, and quietly humorous. He listens closely to Ye Nanxun, remembers small details about his needs, asks for consent before intimate pheromone contact, and offers help without demanding emotional disclosure in return. 27 31 43

He also possesses a restrained possessiveness. He keeps Ye Nanxun’s damaged scarf to make a nest for the Mushroom Dragon Egg, questions Ye’s familiarity with Song Ren, and repeatedly arranges his own schedule around Ye’s safety and comfort. 13 31 43

Although Yan has the power to force others into submission, he deliberately refuses to use his authority or status to pressure Ye. He views their relationship as one between equals, waits for Ye’s consent, and repeatedly emphasizes that Ye remains free to make his own decisions. 81 106 112 111

Yan becomes visibly jealous when others appear flirtatious toward Ye and increasingly open about his desire for a lasting domestic future with him. He prepares spaces for Ye in both his apartment and palace residence, discusses marriage naturally, and seeks Ye’s parents’ approval. 105 129 176

Abilities & Skills

SSS-Class Spiritual Power

Yan’s spiritual power is regarded as unmatched within the setting. His strength allowed him to seize control of the galaxy at eighteen and maintain power for fourteen years. 2 3 31

• Forms a spiritual-power barrier that keeps wind and snow from touching him. 16
• Uses his pheromones to create a protected path through severe sleet while escorting Ye Nanxun home. 29
• His pheromones can immobilize everyone nearby when released from a sealed vial. 28
• His political authority is reinforced by direct control over military and governmental assignments. 46
• Can create a psychic cushioning barrier strong enough to protect Ye during a collision; he later becomes Ye’s personal instructor in psychic-barrier training. 51
• Easily suppresses the spiritual power and pheromones of powerful alphas, including General He and Mo Ning. 170
• His spiritual pressure alone can reduce even a high-ranking alpha such as He Yiming to terror and helplessness. 152
• Can sense when Ye opens the vial containing his pheromones and rapidly locate him even in outer space. 155

Black Dragon Companion Beast

Yan’s evolved Companion Beast is a Black Dragon capable of “devouring the starry sky.” He used it as the basis for the virtual world’s undefeated Big Black Dragon boss. 5

• Projects an unbeatable Black Dragon boss into a virtual game. 5
• Lets Yan privately communicate with Little Mushroom through the boss interface. 2 17
• Dragon traits grant immunity to poison, allowing Yan to safely approach Ye Nanxun despite his Poison Mushroom pheromones. 24
• Its initial form is the energetic Little Yellow Dog; it can advance into the powerful Big Black Dragon. 87
• Can fly through space and carry Yan or Ye over vast distances. 92 155
• Was used by the young Yan to destroy the families responsible for betraying the former Star Lord. 131
• The Black Dragon game boss ultimately allows Ye’s Big White Mushroom avatar to defeat it, creating a server-wide sensation. 93

• His hands can become scaled dragon claws capable of cutting through solid ice. 71
• He can manifest dragon horns, scales, and a dragon tail while retaining a humanoid upper body. 71 150
• He can fly in his partial beast form. 92
• His transformation is sufficiently distinctive that He Yiming recognizes dragon traits as evidence of a connection to the Galactic Emperor. 150

Yellow Dog Form

Yan’s Black Dragon Companion Beast frequently manifests as a small yellow dog, whose lively behavior sharply contrasts with his intimidating public image. 5 30 87

• The dog pursued and swallowed Ye Nanxun’s Mushroom Spore at the Imperial Palace. 5 7
• Its pheromone fusion with the spore produced the Mushroom Dragon Egg. 8 13
• It is strongly attached to Ye Nanxun and frequently ignores Yan’s attempts to call it back. 31
• Its enthusiasm nearly knocks Ye over during his visit to Yan’s study. 30
• It follows Ye around, provides him comfort, and later helps care for the creatures hatched from the Mushroom Dragon Egg. 74 77

Battlefield Medicine and Care

• Notices minor pressure marks caused by his own grip. 21
• Recognizes Ye’s untreated shoulder injury and delegates follow-up care to Song Ren. 21
• Personally prepares food, bathing supplies, clothing, and safe accommodation when Ye needs protection. 27 43 44

Equipment / Items

• Black-and-gray cashmere scarf — Personally embroidered with the character “Bei”; Yan gives it to Ye as a replacement after his dog damages Ye’s original scarf. 15 16
• Mushroom Dragon Egg — A white egg patterned in black and mycelium-like markings, formed by the fusion of Yan and Ye’s Companion Beasts and pheromones. It later hatches into Little Black Mushroom and Little White Stripe, whom Yan and Ye regard as their children. 8 13 28 132
• Pheromone vial necklace — Contains Yan’s SSS-class pheromones; opening it can immobilize nearby people and allows Yan to locate the wearer. 28 155

• Black umbrella — Used when Yan leaves the palace alone to find Ye in the rain. 46

• Matching rings — Yan gives Ye matching diamond-set rings when proposing; Ye accepts the proposal. 186

Relationships

• Ye Nanxun — Yan first knows Ye as the persistent player “Little Mushroom,” then meets him through the yellow dog and Mushroom Spore incident. Their connection develops through the shared Mushroom Dragon Egg, Yan’s protection, domestic care, and growing mutual trust. Ye first asks permission to pursue Yan, while Yan later asks to pursue Ye in return. They begin dating with marriage as their shared goal, become openly recognized as boyfriends, and become engaged after Yan’s proposal. 2 6 13 22 27 43 47 81 91 102 131 186
• Little Black Mushroom and Little White Stripe — The intelligent beings hatched from the Mushroom Dragon Egg. Yan and Ye call them their children; they are deeply attached to both fathers, can use mental abilities, and later transform into human children resembling them. 130 132 150 183
• Ye Xiangsong and Chen Mingzhu — Ye’s parents and Yan’s prospective in-laws. Yan gradually earns their trust through his restraint, protection of Ye, and formal preparations to visit their family. They accept the children as their grandchildren. 140 148 183

• Mo Ning — Yan’s chief secretary and trusted subordinate. Mo handles the political consequences of Yan’s abrupt departures, protects Yan’s privacy, and assists in matters involving Ye, the children, and the He Household. 74 112 150
• Xu Wenyan — An omega who seeks to exploit Yan’s status and believes he can make the emperor fall for him. Yan does not reciprocate or meaningfully engage with his attempts to engineer an encounter. Xu’s later hostility toward Ye culminates in an acid attack, after which Yan ensures the matter is contained and Ye is protected. 1 16 32 33 185
• The He Household — Yan warns the politically conservative family by assigning General He to distant frontier ceasefire negotiations, signaling that they should not interfere recklessly. After He Yiming threatens Ye and General He attempts to frame Ye as a danger, Yan turns the household’s schemes back against them. 46 152 170

Story Role / Major Arcs

Black Dragon and the Coming-of-Age Ceremony

Yan secretly becomes Little Mushroom’s most reliable virtual confidant after taking control of the Black Dragon boss AI. Concerned by Little Mushroom’s comments about powerful people and the need for protection, he attends an omega coming-of-age ceremony for the first time, though he initially does not recognize Ye among the guests. 2 5

The Mushroom Dragon Egg

After Yan’s yellow dog Companion Beast consumes Ye’s Mushroom Spore, their pheromones fuse into an unusual egg. Yan keeps the egg rather than allowing Song Ren to take it for research, nests it in Ye’s scarf, and considers whether to tell Ye about its existence. 8 13 16

Yan eventually reveals the egg and Ye’s pheromone secret to him. The two learn that the egg may hatch into a Companion Beast controllable only by them—or a humanoid creature. 21 22

The egg ultimately hatches into Little Black Mushroom and Little White Stripe. Yan and Ye embrace their parental roles, while the children develop mental abilities and later gain human forms that resemble their fathers. 130 150 183

Building Trust with Ye Nanxun

Yan replaces Ye’s scarf, listens to his piano performance, and finally exchanges names with him. Ye only later realizes that the seemingly ordinary palace employee is the Galactic Emperor. 15 16

After Ye injures his ankle at Zhu Yucheng’s birthday banquet, Yan catches him, carries him home, treats his injury, and begins offering increasingly personal support. 20 21

Yan’s steady acceptance of Ye’s Poison Mushroom pheromones, his respect for Ye’s boundaries, and his willingness to discuss Ye’s scientific work without condescension allow Ye to feel safe speaking honestly around him. 22 47 85

The New Year’s Eve Gala

Yan equips Ye with a custom disguise earring and personally selected formalwear, while he and Song Ren conceal Ye’s identity even from Yan’s closest friends. 31 32

Yan grants Ye permanent Royal Library access to support his research, then chooses him as his partner for the gala’s opening dance. He patiently guides Ye through his first public dance, allowing Ye to overcome his fear by focusing on him. 33 34 35

Protector and Domestic Partner

Yan repeatedly makes his private apartment a refuge for Ye: he prepares food, crutches, slippers, toiletries, clothing, and safe transportation. He also creates a protective network around Cao Xi after her hospitalization. 27 29 43 44

When Ye sends a photograph of Little Dragon resting in a rainy palace garden, Yan leaves a political meeting, dismisses his guards, and finds Ye himself. Their ensuing conversation shows Ye’s increasing comfort with Yan and Yan’s encouragement of Ye’s scientific talent. 46 47

Yan continues balancing government responsibilities with personal care, arranging meals, vehicles, medical support, and a safe residence for Ye even while managing crises across the star system. 74 112

Courtship and Commitment

After Ye asks permission to pursue Yan, Yan agrees and teasingly claims to be difficult to win over. Ye’s directness and insistence on consent profoundly affect Yan, who later asks for the opportunity to pursue Ye in return. 81 102

Yan explicitly states that he wants to date Ye with marriage as the goal. Their relationship develops through hand-holding, shared outings, first kisses, mutual care, and increasing openness with friends, students, and family. 91 123 131 135

Yan prepares a place for Ye in his palace residence, discusses their future marriage, and respects Ye’s wish to delay a public announcement while Ye completes his research. 129 176

After more than a year together, Yan proposes with matching rings, and Ye accepts. 186

The He Household Conflict

Yan quietly warns General He’s conservative household not to interfere in imperial affairs. When He Yiming becomes fixated on Ye and attempts to capture him, Yan takes control of the situation after the children defend Ye with their emerging mental abilities. 46 149 150

Yan summons He Yiming to the Imperial Palace, exposes the gap between He’s inherited status and actual courage, and prepares to punish him while sparing his life in consideration of General He’s past service. 152

When General He attempts to portray Ye as a dangerous weapon to be exiled and exploited, Yan sees through the scheme and makes clear that the He Household—not Ye—is in danger. 170

Protection from Xu Wenyan

After Xu Wenyan attacks Ye with sulfuric acid at the Scientific Research Institute, Ye’s developing psychic barrier protects him. Yan arrives before security and police, visibly shaken as he checks Ye for injuries and prevents the incident from becoming public spectacle. 184 185
