Arc 1The Fragment and the Abyssal Corridor
Ling uncovered Root’s experiments, allied with Tsunade to bring down Danzo, and joined the Anbu as Crow. During a mission in Amegakure, Pain’s trap separated him from his team and led him to Xi, whose clan contract and the Ryūmyaku powered the Abyssal Corridor.
- At Hiruzen Sarutobi’s funeral, Ling sensed Root watching him, then accepted a mission to investigate a sleeping town and left Konoha with Aoi and Inuzuka Gaku.
- Ling and his teammates traced the town’s affliction to a maple tree and a root-bound corpse, then fought Root operatives over a damaged scroll and its Yin Release core.
- Ling absorbed a fragment of the scroll, awakened unusual scarlet eyes, killed two Root attackers, and returned to Konoha with the injured Inuzuka Gaku and Kuromaru.
- Ling met Tsunade in secret, gave her evidence of Root’s actions, and accepted protection in the Anbu training program while sharing intelligence about Danzo’s hidden laboratory.
- Ling discovered signs of forbidden experiments beneath the Forest of Death and survived a shadow monster’s attack, prompting Tsunade to increase his protection and move against Danzo.
- Ling warned Tsunade of a possible Orochimaru-Akatsuki transaction and helped bait Danzo’s attempt to seize his ocular power, allowing Tsunade’s forces to destroy the laboratory and defeat Danzo.
- Tsunade killed Danzo, disbanded Root, and appointed Ling Special Jōnin and an Anbu under Fox, who gave him the codename Crow.
- Fox sent Ling and Azure Phoenix to Amegakure to investigate Akatsuki activity, but Pain and Konan ambushed the team and Ling escaped through an underground fissure.
- After being swept down an underground river, Ling found Xi chained to Six Binding Pillars and learned that Pain was twisting her clan’s contract with the Ryūmyaku to power the Abyssal Corridor.
- As Pain accelerated the contract’s erosion, Xi directed Ling to damaged runes on a pillar, and Ling struck them with the Fragment’s power using “Purifying Erosion: Barrier Break!”
