Background

Su Yu and his older brother, Su Xing, lost their parents in a car accident. The trauma left Su Yu hospitalized for several years before he recovered; Su Xing then focused on supporting him and giving him a stable life. 2 157

An exceptionally gifted student, Su Yu ranks among the best at Cang City High School. His academic excellence also conceals exceptional Sequence potential: Li Yu identifies him as the highest-ranked Sequence user the organization has seen and recruits him for a capital “study program” that is actually a lethal battle. Su Yu accepts because becoming stronger is the only way he believes he can protect Su Xing. 2 3

Initially, Su Yu treats Su Xing as an ordinary person in need of protection. That belief collapses when he witnesses Su Xing kill a third-tier Sequence user in one strike. Thereafter, Su Yu protects his brother’s secret identity, repeatedly attributing Su Xing’s interventions to a “mysterious expert.” 33 44

Appearance

Su Yu has black hair and a youthful face. A bright golden, hammer-shaped mark sits on his forehead; staring at it for too long can cause dizziness. 2

• Often dresses casually, including black short sleeves and brown jeans. 30
• His Sequence energy is unusually multicolored because he possesses multiple Sequences rather than only one. 200
• His mature expression becomes increasingly solemn as his responsibilities and the threats around Su Xing grow. 142 445

Personality

Su Yu is deeply devoted to Su Xing. His cultivation, decisions, and willingness to take risks are consistently motivated by his desire to protect his brother. He is initially frustrated by his own weakness, particularly after seeing Su Xing’s strength and the widening gap between Sequence tiers, but converts that insecurity into disciplined cultivation. 3 14 94

He is also discreet and resourceful. Rather than expose Su Xing after the latter saves him, Su Yu constructs believable cover stories for the Special Organization. Even after Su Xing’s identity becomes known, Su Yu remains alert to the political and personal risks surrounding his brother. 44 289

As a leader, Su Yu prioritizes others before himself. During the Siege of Windless Mountain, his first response to a mass bombing is to direct nearby fighters to take cover rather than protect himself. 445

Abilities & Skills

Judgment Sequence

Su Yu possesses a high-ranked Judgment Sequence and three Sequence Gates, making him one of the Special Organization’s most promising young members. 103

• Can destroy implanted Puppet White Worms within hostile targets with the command “Break.” 383
• Previously needed to sacrifice lifespan when using Judgment against powerful opponents; this cost no longer applies against relatively weak targets. 383
• Used his Sequence to kill a powerful opponent during the Siege of Windless Mountain at the cost of three years of his lifespan. 446

Voice Transmission Sequence

Su Yu can communicate telepathically with Su Xing, allowing the brothers to exchange information without drawing attention. 105 157

• Uses Voice Transmission to warn Su Xing of investigations, missions, and Organization decisions. 105 145
• Believes the communication cannot be intercepted so long as it operates within the Sequence’s rules. 205
• At sixth tier, the Sequence evolves so that Su Yu can hear Su Xing even when Su Xing speaks normally. 409

Crimson Energy Spear

Su Yu can condense red Sequence energy into a spear for direct combat. 10 32

• Uses the spear in close-quarters exchanges with Spirit Cult followers. 10
• Can form it while lying in ambush during Special Organization operations. 32
• His spearwork later becomes refined enough to deflect gunfire and disperse hostile mist. 383

Multiple Sequences

Unlike most Sequence users, whose energy reflects a single Sequence, Su Yu possesses several. 200

• His additional Sequences are generally lower-ranked than Judgment, limiting his overall combat performance despite his potential. 200
• His varied powers nevertheless give him unusual adaptability and make him difficult to assess through aura alone. 200

Equipment / Items

• Black Sword — Su Xing’s sword, temporarily wielded by Su Yu during the Spirit Sea incident. Its sword spirit offers to take control of Su Yu’s body to ensure his survival. 419
• Organization combat suit — Worn during Special Organization operations. 199

Relationships

• Su Xing — Older brother and Su Yu’s central motivation. Su Yu initially tries to protect him as an ordinary civilian, then protects Su Xing’s hidden identity after learning the truth. 3 33 44
• Li Yu — Organization senior who approaches Su Yu under the guise of a homeroom teacher, recruits him for the capital program, and pushes him to cultivate. 2 3
• Shen Ruyun — Personal bodyguard and frequent mission partner assigned to protect Su Yu. 12 13 32
• Lu Anning — Su Xing’s disciple and Su Yu’s ally. She protects Su Yu during the Windless Mountain bombardment, while the two later face seventh-tier enemies together. 445 446
• Li Longxuan — Senior leader whose strength intimidates Su Yu, but who recognizes Su Yu’s potential and later entrusts him with increasing responsibility. 205 577
• Black Sword’s sword spirit — Offers Su Yu temporary control of the Black Sword and his own body during a life-threatening confrontation. 419

Story Role / Major Arcs

Spirit Cult Campaign

Su Yu becomes involved in the Special Organization’s response to Spirit Cult activity across Cang City. He gathers intelligence from Liu Ming, works alongside Shen Ruyun, and repeatedly becomes a kidnapping target because of his rare Sequence potential. 7 22 25

His rage at the Spirit Cult’s threat to Su Xing triggers his advance to second tier. Later, when Su Xing saves him from a third-tier priest, Su Yu discovers that his supposedly ordinary brother is the mysterious swordsman protecting him. 30 32 33
