Background / History

Lin Yu is a transmigrator whose main body is restricted by the Main Universe, though even under suppression he is described as far beyond ordinary intelligent beings and comparable to a Dimensional Demon God 5.

Before joining the chat group, he had already begun researching a cultivation path for humans in the Frieren world. Because humans there are eroded by magic power, he concluded that cultivators must be protected from magic power from infancy until their meridians mature enough to receive implanted Spiritual Roots. His earliest test subjects were the old village chief's newborn twins 29.

He developed artificial Spiritual Roots and an Element Reaction Furnace capable of implanting them. He used this research to guide Su Haoming and Yun Ye after determining that neither possessed Magic Aptitude 27.

Personality

Lin Yu is curious, resourceful, and strongly driven by the pursuit of knowledge. He studies unfamiliar power systems, develops techniques for others, and seeks ways around cross-world restrictions rather than accepting them 27 208 252.

Despite his overwhelming strength, he generally avoids harming innocents and acts with deliberate self-awareness rather than merely following habit 63. He can be playful, indulgent toward children and trusted companions, and willing to entertain harmless pretenses, such as performing a staged compatibility divination for Yun Ye and Xin Yue 101 208.

He is also calculating when necessary. Lin Yu fabricates identities, possesses substitute bodies, uses contracts to establish soul connections, and conceals himself from the Heavenly Dao to obtain knowledge and laws 33 329 347.
