Vault Sheath

The Vault Sheath is a former Li Palace treasure whose interior holds an ocean of sword intents and Chen Changsheng's collection of famous swords. It serves simultaneously as sheath, spatial store, weapon, and cultivation environment. (Chapters 489–495, 620–621, 774, and 915)

History

A Li Palace treasure becomes a sword vault

Once kept in the Li Palace, the Vault Sheath comes to Chen Changsheng as a gift from Shang Xingzhou. By its public identification, Chen has already filled its internal sea with sword intents and the famous swords recovered from the Garden of Zhou. Continued residence within the sheath nourishes those weapons and restores their edges, allowing Chen to develop a many-sword arsenal whose attacks can emerge even when his Stainless Sword is pinned. (Chapters 489–495, 518, 553, and 620–621)

A reclaimed gift returns to war

The sheath remains Chen's constant companion, serving as weapon, training environment, and storage through successive campaigns. Shang later seizes it into his sleeve during their confrontation, forcing Chen to improvise while trying to take it back with his spiritual sense. It falls at Shang's feet after his defeat and is again in Chen's use during the final northern war, when its swords illuminate the dark grassland. (Chapters 674–807, 908–1028, 1073, 1101–1114, and 1126)

Abilities and properties

• Its interior contains an ocean of sword intents and can store hundreds or thousands of physical swords, which Chen can launch together or individually. Controlling many simultaneously requires sufficient spiritual sense and calculation. (Chapters 495, 518, 620–621, 674, and 1021)
• Swords resting within it are nourished, regaining sharpness and forming a close mental coordination with Chen over time. The original ten-thousand-sword dragon formation cannot be reproduced after the Garden's swords return to their mountains. (Chapters 620, 715, and 774)
• The sheath can join the Stainless Sword or another blade as a composite long weapon, increasing reach, sharpness, or killing intent, and its body can directly block a spear. (Chapters 896, 908, 926–988, and 1025–1028)
• It also functions as practical spatial storage for small tools and clothing, but the evidence does not make its capacity or access unconditional. (Chapters 807 and 915)
