Sharingan

Awakening and perception

The Sharingan is explicitly identified as the Uchiha Clan's Kekkei Genkai. A fully developed Three-Tomoe Sharingan at age ten is described as unprecedented in Uchiha history, making Liuyun's early awakening politically dangerous if exposed. 1 4

• Its dynamic vision can follow movements faster than an ordinary jōnin's Body Flicker Technique and predict an opponent's landing point. 271
• Sharingan genjutsu is particularly effective against Tailed Beasts and enormous summoned creatures; Liuyun repeatedly subdues the Black Dragon through eye contact. 133
• Emotional upheaval can trigger awakening. Uchiha Kazuhiko awakens his Sharingan amid an argument, while Liuyun awakens his Mangekyō during overwhelming pain and anger. 68 222
• The Three-Tomoe Sharingan is considered standard equipment for Uchiha jōnin, emphasizing how abnormal Liuyun's childhood awakening is. 4

Eye power and inheritance

Liuyun distinguishes ocular power from ordinary chakra, identifying the essence of Sharingan eye power as Yin Release. 194

• The Uchiha Clan preserves the eyes of deceased members because Sharingan from direct blood relatives possess high transplant compatibility. 194
• A compatible transplanted eye can restore sight and may provide power greater than the recipient's former eye. 194
• Liuyun theorizes that Eternal Mangekyō Sharingan is created by merging the ocular power of two related Mangekyō pairs rather than merely exchanging physical eyes. 194
• The blindness associated with excessive Mangekyō use is attributed to depletion of ocular power; Liuyun believes fusion of two Mangekyō eye powers can remove this burden. 194
• Liuyun's left eye remains blind after he uses Izanagi. Neither his Mangekyō awakening nor the initial awakening of his Sage Body restores its sight. 356

Advanced ocular techniques

• Black Sun — After absorbing Shisui Uchiha's right Mangekyō power, Liuyun's left eye awakens an ability that deprives an area of light, blocks vision, and interferes with enemy eye techniques. 362
• Eternal Night — Liuyun uses this Mangekyō dōjutsu to seal Hagoromo Ōtsutsuki's ocular abilities. It specifically seals Yin Release, preventing opponents from using techniques dependent on it. 458 580
• Nine-Tomoe Rinnegan genjutsu — Eye contact with Ōtsutsuki Shenxu's Nine-Tomoe Rinnegan directly controls Sasuke and Madara, despite both being Rinnegan users. 573
• Rinnegan absorption — Liuyun demonstrates that Rinnegan-type power can absorb energy-based ninjutsu and chakra, a trait he identifies as shared by the Ōtsutsuki Clan's Karma. 487

Bloodline Interactions

Liuyun possesses Uchiha and Senju ancestry. Tsunade and Mito Uzumaki consider the possibility that this combination contributed to his unusually strong eyes and chakra reserves comparable to a jōnin while still an academy student. 39 47

• This dual heritage is treated as an abnormal “mutation” rather than a common result of Uchiha–Senju intermarriage. 47
• Mito considers knowledge of Liuyun's suspected Sharingan and immense chakra a potential fatal danger, ordering Tsunade to keep it secret. 47
• When Liuyun awakens his Mangekyō and Senju bloodline, his chakra natures expand from Fire, Lightning, and Water to all five basic elements, with Yin and Yang also manifesting. 250
• Liuyun's later Sage Blood is identified by Orochimaru as Yang Release blood and is potent enough to revive Asuka through transfusion. 431

Research and Preservation

Kekkei Genkai are valuable enough that both clans and laboratories preserve their users' bodies or eyes for future use and study.

• The Uchiha Clan maintains a long-standing system for preserving deceased members' Sharingan, originally associated with the era when Izanagi was abused. 194
• Orochimaru's laboratory stores numerous Kekkei Genkai users' corpses in preservation tanks for research. 607
• Liuyun considers maintaining entire corpses impractical, preferring to retain smaller genetic and ability records instead. 607
• The preservation and study of bloodline abilities consumes enormous resources, making Orochimaru's research facility one of the world's most expensive operations. 607
