Background / History

Priesthood and Sacrificial Duty

Bo Saixi was selected as the Sea God’s High Priestess during childhood. Her life thereafter involved little contact outside the island’s senior figures, including the Sacred Pillar Douluos 68.

Her final duty as High Priestess is to sacrifice her life to open the Sea God Ninth Trial for the divine inheritance’s successor. Despite serving Poseidon, she wishes to survive. After witnessing Li Changsheng’s strength, she considers befriending him a possible way to escape that fate 26 62.

Defense of Sea God Island

During Martial Soul Hall’s invasion, Bo Saixi intervenes against Qian Daoliu and draws both him and the concealed Tang Chen away from the island to avoid harming innocents. When both men propose marriage, she encourages their rivalry by declaring that she will only seek an equally powerful partner 19.

Tang Chen narrowly wins their sparring match, but neither combatant exhausts himself as much as Bo Saixi had hoped. After learning that the island’s defenders have repelled the invading force, she challenges both men together. Sustained by the ocean’s Soul Power, she defeats them and obtains Martial Soul oaths that they will never offend Sea God Island again 20.

She then investigates a distant thunderous aura to ensure the island’s safety. There, she witnesses Li Changsheng overpowering the Deep Sea Demonic Whale King—an enemy she could not defeat herself. Although relieved at the prospect of its death, she obeys Poseidon’s decree to preserve it as a future successor’s soul ring and trial 20 21 22.

Hosting Li Changsheng

Bo Saixi invites Li Changsheng to Sea God Island and personally welcomes him with the island’s elders. Her hospitality combines respect for his power, a favorable personal impression, and hope that he can help her avoid her sacrificial destiny 23 26.

She arranges a banquet and instructs Hai Long Douluo to let Li Changsheng choose freely from the island’s treasury. When Hai Long objects to the potential losses, she explains that the arrangement fulfills both her promise and the Sea God’s wishes 27.

Recognizing Ye Han Yue’s exceptional talent, Bo Saixi offers to accept her as a direct disciple and appoint her as the next High Priestess. Ye Han Yue respectfully declines because she already follows Li Changsheng 37.

Relationship with Li Changsheng

Bo Saixi initially doubts that she is worthy of Li Changsheng, citing their age difference and his apparent potential to become a god. Ye Han Yue offers help in winning his affection in exchange for a future favor. Bo Saixi recognizes the disciple’s own feelings for him and agrees to cooperate 47 48.

She directly confesses her love in Chapter 48, and the two become intimate that night. Their subsequent relationship includes affection and teasing, but also an encounter in which Li Changsheng proceeds despite her requests to stop and let her rest 48 49 50.

Li Changsheng later visits the Sea God Temple partly to address her sacrificial duty. Bo Saixi waits there for three days without eating or sleeping after he disappears into Poseidon’s space. On his return, she embraces him before the Sacred Pillar Douluos, and he tells her that he raised the Ninth Trial sacrifice with Poseidon. Their public affection earns a rebuke from the Sea God; the provided account does not explicitly confirm that her obligation is canceled 62 63 67.

Cultivation and Later Events

After receiving cultivation methods and spear arts from Li Changsheng, Bo Saixi spends increasing amounts of time training at sea. She insists that growing stronger is necessary if she is to keep pace with him and remain by his side 70.

Her jealousy over his closeness with Hai Nv Douluo leads her to ignore him for several days. She eventually invites him to a banquet and accepts his apology. Later, she uses aged wine to intoxicate him and arranges an encounter involving Ye Han Yue and Hai Nv; Li Changsheng subsequently confronts her as the scheme’s instigator 76 77 78 80.

Following further seclusion, she reaches late-stage Level 99. When Li Changsheng eventually leaves Sea God Island, she and Hai Nv do not join the public farewell at the port. Instead, they watch his departure from a nearby mountain 103 121.

Appearance

• Apparent age: Her face appears no older than thirty; her actual age is not stated 19.
• Hair: Long, sea-blue hair flowing down her back 19.
• Eyes: Clear blue, deeper than the ocean, with an aged quality suggesting long experience 19.
• Clothing: Introduced in a bright red robe; later wears an elegant outfit gifted by Li Changsheng 19 54.
• Bearing: Noble, graceful, warm, and soothing, with an aura compared to the sea 19.

Personality

Bo Saixi combines a gentle public manner with tactical calculation. She redirects dangerous fighting away from innocents, exploits Qian Daoliu and Tang Chen’s attraction to make them compete, and uses her eventual victory to secure binding promises protecting Sea God Island 19 20.

Her devotion to Poseidon does not eliminate her desire for self-preservation. She obeys the order to save the Deep Sea Demonic Whale King despite wanting the island’s enemy removed, while privately seeking a way out of her own sacrificial duty 21 22 26.

Though revered by island residents as aloof and immaculate, she is inexperienced and easily embarrassed in romance. Her affection for Li Changsheng exposes insecurity, jealousy, and fear of losing him, but also motivates determined cultivation. She shows a gentler, nurturing side when holding and comforting the Mini Dragon 33 47 67 68 70 75 76.
