Background / History

Lan Sen was originally an unnamed, eighty-thousand-year-old Blue Silver King who had cultivated in the Blue Silver Ancestral Land for so long that he possessed no personal name. He was stunned when the newly arrived Lan Lingcang rose from ordinary Blue Silver Grass to Blue Silver King and then Blue Silver Emperor in less than a day. Confronted with Lan Lingcang's imperial bloodline, he submitted without resistance and explained that Ah Yin's continued existence prevented Lan Lingcang from becoming the clan's sole true Emperor 3.

After Lan Lingcang defeated the Titan Giant Ape and Azure Bull Python, he prepared to leave the ancestral land. Before departing, he established defensive energy around the site and bestowed the name Lan Sen upon the Old Blue Silver King. Lan Sen regarded receiving a name from the Emperor as an immense honor 9.

Lan Sen later acted as Lan Lingcang's chief representative within the ancestral land. He gathered the other Blue Silver Kings at Lan Lingcang's command when the clan anticipated a human-led crusade, then oversaw their defense preparations through the Plant Network 19 32.

Appearance

Lan Sen originally manifested an aged face through spiritual power, reflecting his long cultivation and seniority among the Blue Silver Kings 3. After his bloodline evolution, blue-gold patterns across his skin deepened and his life aura became markedly denser 62.

• Aged spiritual manifestation during his time as the Old Blue Silver King.
• Blue-gold Blue Silver Grass patterns that became more pronounced after his evolution.
• A powerful life aura characteristic of his emperor-grade bloodline.

Personality

Lan Sen is deeply reverent toward Lan Lingcang and treats the Emperor's commands as absolute. He accepted Lan Lingcang's authority immediately, received his name with visible excitement, and repeatedly volunteered for dangerous assignments before the other Blue Silver Kings could respond 3 9 24.

Despite his loyalty, he is a composed and capable administrator. During the defense of the ancestral land, he dismissed minor intruders as unworthy of direct action, ordered spirit beasts to ambush them along their routes, and coordinated the other Blue Silver Kings through the Plant Network 32.

He is also unwaveringly self-sacrificial. Lan Sen declared that he was willing to die for Lan Lingcang and Ah Yin, then followed through by sacrificing himself as Ah Yin's seventh Soul Ring after reaching 200,000 years of cultivation 31 83 88.
