Background

After being laid off, Lin Chen began using the Daddy System's rewards from household labor and time spent teaching Lin Xiaoqian. Cleaning improved his Physique, while storytelling steadily raised his Fairy Tale Creation ability. The System's skill framework—from ordinary through Mythical—was based on terms Lin Chen proposed himself 2 4.

Determined to provide for Xiaoqian without relying on others, he registered Lin Yu as a pen name and began publishing original fairy tales on the Childlike Heart Network. His work gained immediate attention, leading to a contract and a 300,000-yuan signing bonus 11 12. He later confirms to his parents that Xiaoqian is his daughter and prioritizes integrating her into the Lin family 14.

Lin Chen and Xu Mengyao legally marry after she brings Xiaoqian into his life. Though their relationship begins with uncertainty and practical concerns, they gradually become a genuine family, publicly marrying in a formal wedding ceremony later on 21 129 355.

Appearance

Lin Chen is 1.8 meters tall and appears lean despite his unusually dense muscles and bones. His continual Physique growth improves his skin, facial features, charisma, and overall attractiveness 35 119 127.

• Clearly defined eight-pack abs and a physique that surprises those who initially judge him as thin 70 125.
• Weighs close to 160 pounds despite maintaining a slim outward build, due to increased bone and muscle density 127.
• His appearance becomes increasingly refined as his Physique improves and bodily toxins decrease 35.

Personality

Lin Chen is family-centered above all else. He repeatedly chooses time with his children over licenses, fame, political status, or professional expansion, and he considers being a stay-at-home father his primary role 174 246. His teaching is patient and playful, whether he is telling Xiaoqian stories, practicing Tai Chi with his family, or teaching Lin Dongyao with model airplanes 26 313 553.

He is confident but deliberately low-key. Lin Chen initially conceals his identity as Lin Yu, declines opportunities for publicity, and avoids selling artworks merely for money or fame 35 41 180. Even after becoming internationally influential, he frames his pursuits as self-improvement, invincibility, and longevity rather than worldly authority 451 551.

When threatened, he is calm, strategic, and uncompromising. He refuses Zhao Tianyou's attempt to buy him off, withstands public-opinion attacks without panic, and retaliates against hostile organizations through information, financial pressure, technology, and overwhelming force when necessary 64 340 405.
