Background / History

Early Life in the Cao Clan

Cao Yu is a reincarnated person with memories of another world and access to a system—not the reincarnated deity some observers believe him to be. Born into the Cao Clan of Star Luo City, he is raised by Cao Xiang and Luo Lingyun and doted on by his grandfather, Cao Yanjun 8 11 18.

Ten black-clad protectors accompany him during infancy. Although his family treats them as powerful independent seniors, they are actually his Shadow Clones. Their presence helps draw the attention of the Star Luo Imperial Family, Tang Sect, and Nine Treasures Glazed Tile Sect 7 10 11.

His childhood friendships with Tang Ya, Xu Jiujiu, and Ning Tian become the foundation of marriage arrangements between their families. Ning Tian is already his fiancée when he is approximately three years old. At six, he undergoes his formal Martial Soul Awakening at the imperial residence before obtaining his first Soul Ring 17 18 22.

Shrek Academy and Research

Cao Yu enters Shrek Academy after his Martial Soul mutation. Together with Wang Dong and Xiao Xiao, he wins the freshman assessment tournament and receives core disciple status 36 37 83.

Alongside his studies, he expands his businesses and establishes a Soul Tool research operation. He teaches students mathematics, physics, chemistry, and biology, then purchases permanent knowledge cards for Shadow Clones to provide additional instructors. Xu Jiawei supports the project by arranging imperial purchases of its Soul Tools and sending more people to study there 97 100.

Tournaments and Conflict

While traveling with the Shrek Inspection Corps, Cao Yu demonstrates his modified Flying Soul Tool by destroying a group of Evil Soul Masters with three missiles. During the ensuing tournament, a bracelet he gives Ma Xiaotao protects her against the Sword of Judgment, helping Shrek secure the championship. He later steals the Sun Moon team’s Storage Soul Tools 113 115 127.

In a subsequent tournament, he uses Electrolux’s soul-control legacy against a Holy Spirit Sect contestant, bombards Yue Guling with multiplying golden projectiles, and transforms into a Level 8 Soul Tool Turret against the Heavenly Dragon Sect 226 227 234.

Family and the Heavenly Realm

After his school years, Cao Yu’s relationships develop into a large household. He promises Luo Yan’s parents that he will marry her after graduation, and later selects January of the following year for his wedding with Xu Jiujiu. By the time his wives are pregnant, he is personally caring for them and preparing supplies for their children 249 254 265.

Later, he completes divine investitures and brings his friends and relatives to the Heavenly Realm. He explains that this realm is independent of the traditional Divine Realm and follows the path of immortality. He also establishes trials through which ordinary people can earn heavenly soldier positions and advance through merit, strength, and influence 288.

Appearance

• Childhood: Chubby cheeks, fair skin, and fine, delicate features; adults repeatedly remark on his good looks 8 11.
• Growth: At eleven, he is already nearly as tall as his mother. At Shrek, he stands two heads taller than Xiao Xiao 26 56.
• Build: Develops a firm, muscular physique and broad, warm hands 56 204.
• Ability-related changes: His eyes turn gray when Elder Yi’s power or inherited necromancy is active 131 226.

Personality

Cao Yu is playful, calculating, and skilled at appearing innocent. Even as a child, his internal thoughts reveal an awareness far beyond his apparent age. He uses charm and acting to navigate awkward situations, while his wives later tease him for his shameless courtship tactics 12 15 267.

His spending habits are driven by the system rather than conventional thrift. He resents losing access to money that could generate Tenfold Cashback and prefers buying ore to accepting free mining areas. He also applies knowledge from his original world to teaching and technological development 10 97 100.

He is affectionate toward his family and protective of his household. As a child, he promises to protect his mother; later, he personally cares for his pregnant wives and worries about spies threatening their safety. His concern for others also extends beyond his immediate circle: when Xu Jiujiu asks whether the empire’s people are happy, he acknowledges that suffering may remain hidden beneath visible prosperity 26 254 265.

In combat, he can be ruthless toward hostile Evil Soul Masters, but he restrains his strength during training and stops his duel with Wu Ming once he has secured victory 108 115 209.
