Background

Li Weide is a transmigrator who possesses foreknowledge of Tom Riddle’s future, allowing him to read Tom’s ambitions and fears from their first meeting. He introduces himself according to local naming custom as “Weide Li,” though he prefers to be called Weide 3.

He tells Zhang San that he grew up in an orphanage, but exploits a fabricated connection to an ancient Chinese Li family when pure-blood society demands a lineage. The bluff earns him influence among British pure-blood families, who attribute unexplained knowledge and resources to his supposed family background 64 327 332. He later establishes an actual Li family on Wangwu Mountain, using cloned people implanted with souls and memories while seeking to enrich its library with other families’ inheritances 537.

Before entering Hogwarts, Li Weide studies extensively and develops unusually advanced Transfiguration. At Hogwarts, his Ancient Magic talent draws Dumbledore’s attention, while a trapped “senior female student,” later known as Miravia, teaches him in Dreamscapes and becomes central to his research into Ancient Magic and Residue 37 64 242.

Appearance

Li Weide is a young wizard with an Asian appearance. He usually wears a wizard robe or an outer robe designed to conceal the large amount of equipment he carries 303 554.

• His black robe can be transfigured into a fitted trench coat. 228
• The robe is unusually durable and contains numerous pockets enhanced with Undetectable Extension Charms. 228 554
• He can use Human Transfiguration to disguise himself as other people. 468
• A temporary Gender Transformation Potion once changed him into a female body during an Ancient Magic experiment. 472 473

Personality

Li Weide is intensely ambitious but unusually aware of his own capacity for corruption. When offered Ancient Magic by a stranger, he refuses because he fears that indulging his desire for power could make him become like the offerer 50. This caution remains a defining contradiction: he pursues power, conducts dangerous research, and plans to unify the world, yet repeatedly sets limits on himself and seeks ways to protect others from the consequences.

He is observant, manipulative, and highly skilled at presenting different faces to different people. He can appear to professors as a model student, to companions as a helpful friend, and to allies as a trustworthy leader, while privately judging relationships through usefulness and strategic value 358. Over time, Tom and Miravia force him to confront the fact that he does care for the people around him, even if he habitually denies it 358 361.

Li Weide is also relentlessly curious. He approaches unfamiliar magic, Daoist arts, alchemy, Muggle technology, magical creatures, and world laws as problems to be tested, understood, and repurposed. His confidence often borders on shamelessness, but he can recognize superior knowledge and actively seeks instruction from Dumbledore, the Four Founders, Miravia, and Nicolas Flamel 249 263 507 510.

Story Role / Major Arcs

Hogwarts and the Mutual Aid Club

Li Weide enters Hogwarts alongside Tom Riddle, quickly establishes himself as a highly capable student, and founds the Mutual Aid Club to provide practical help while gathering talented allies around himself 64 98. He publicly defeats hostile students, privately eliminates a goblin camp threatening Charlie and Annie, and personally trains the club’s core members 92 362.

Ancient Magic and Residue Research

After discovering the dangerous nature of Residue, Li Weide investigates how it affects personality and searches for a way to control it without being corrupted 62 107. His work culminates in freeing Miravia from her confinement by absorbing and transferring part of her Residue into the Hogyoku, though the process threatens his control and health 371.

Hydra and Expanding Influence

Li Weide transforms his school network into Hydra, a larger organization built around strength, research, commerce, and mutual dependence. While the public believes he is Hydra’s chief technical consultant, he is its real controller 362 486. He develops the Mobile Castle, strengthens followers with Pure Magic Power capsules, and delegates recruitment and training to Tom and Andrews 387.

Werewolf War and Public Fame

Li Weide attacks the Werewolf clan during a full-moon transformation ritual, defeats the Wolf King using Ancient Magic, the Hogyoku, magical plants, and the Equalizer of All Beings, then forces the surviving leader to surrender 430 431. Grindelwald publicizes the victory, making Li Weide famous throughout the wizarding world and attracting political and commercial attention 456 463.

Daoist Arts and Eastern Expansion

Seeking knowledge of his ancestral culture, Li Weide studies Daoist arts with Zhang San and adapts meditation, soul study, ritual techniques, and Yuangguang into his own system of magic 468 470 480. He later establishes the Li family on Wangwu Mountain and expands Hydra’s influence into the Eastern wizarding world 537 543.

Parallel Worlds and the False Death God

Li Weide learns that his system originated from another version of himself in a destroyed worldline and begins using Parallel Worlds to gather Merit Points, allies, and power 493 542. He later discovers the false Death God’s deception, receives aid from the real Death God, and prepares for a conflict with a fallen alternate Li Weide whose ambition threatens multiple worlds 575 578.

Awakening as an Ancient Sage

Through reflection on emotion, protection, and the nature of magic, Li Weide realizes that Ancient Magic is fundamentally the power to alter world laws 579. After fully awakening, he can modify rules directly, disguise this power through Ancient Magic, and understands himself as an “Ancient Sage” responsible for passing on that power and pursuing a better world 580 581.
