Background

Lan Yiyi is the daughter of Lan Ya, the current Blue Silver Emperor of the Sun Moon Empire, and Wei Kurong, the Poison Douluo. Her family descends from soul masters who originated from a transformed 100,000-year Blue Silver Emperor and has served the Sun Moon Empire’s royal family for generations. Unlike her mother, Yiyi cannot inherit the singular “Blue Silver” title while Lan Ya remains the current Blue Silver Emperor, despite possessing the same martial soul. 10

She grew up alongside Xu Zhao and openly treats him with affection and attachment. Xu Zhao regards her as his future empress, while Lan Ya and Wei Kurong intended to petition for her recognition as Crown Princess once she reached the Title Douluo realm. 11 37 45

Her cultivation accelerated dramatically after Xu Zhao gave her several 100,000-year resources: Ah Yin’s Blue Silver Emperor Right Leg Bone, the Sky Azure Bull Python’s soul ring and right arm bone, and the Soft Bone Rabbit External Soul Bone. These gains elevated her from Soul Douluo to a level 93 peak Title Douluo within days. 45 55 109 114

Later, she activated the Vast Sea Cosmic Shroud, gained the Sea God’s favor, and began the Sea God Nine Trials on Sea God Island. After reaching level 95 and cultivating her Blue Silver Domain to its third stage, she inherited the Sea God Divinity. 167 172

Appearance

Lan Yiyi resembles her mother, Lan Ya, but carries a youthful, lively presence rather than Lan Ya’s gentle maturity. Following her later soul-bone absorption, her appearance gains a more sacred and noble quality. 11 51

• Fair, snow-white skin and water-blue eyes. 11 48
• Soft blue hair; her facial features are said to be seventy percent similar to Lan Ya’s. 11
• Often wears a light-blue dress. 111 167
• Develops fluffy white rabbit ears after absorbing the Soft Bone Rabbit External Soul Bone. 109
• Her Blue Silver Emperor manifestation is crystalline, with gold and silver light flowing through its veins. 112

Personality

Lan Yiyi is affectionate, lively, and unabashedly devoted to Xu Zhao. She regularly addresses him as “Brother Zhao,” seeks his approval, and readily follows his instructions, including standing guard during his seclusion or assisting in dangerous hunts. 11 52 53

Her devotion is paired with clear ambition. She intensely desired the Blue Silver Emperor Right Leg Bone because of its compatibility with her martial soul and viewed becoming a Title Douluo as the path to securing her position as Crown Princess. 45

In battle, she becomes cold, composed, and confident. She treats opponents who threaten Xu Zhao without mercy and regards captured soul beasts such as Xiao Wu as cultivation resources rather than objects of sympathy. 65 106 111
