Twin Realm Blade

The Twin Realm Blade is the top-graded secret treasure that reverses Southern Cloud King's desperate early fortunes and becomes the foundation of his later combat standing. Its acquisition also binds him by oath to the Undying Underworld Emperor, turning the apparent rescue into a lasting obligation. (Chapters 1074, 1122, and 1193)

History

A treasure planted in an ancient remnant

While pursued and exhausted by enemies, Southern Cloud King enters an ancient remnant and discovers the blade. The remnant was deliberately arranged by the Undying Underworld Emperor: claiming the weapon requires the finder to swear an oath, accept its owner as teacher, and serve him. Southern Cloud King accepts while believing that the owner is dead. (Chapters 1122, 1133, and 1193)

Mastery, status, and inheritance

After fully mastering the blade, Southern Cloud King turns his fate and secures his later position. Study of the treasure does more than raise his immediate output: he creates a personal killing move from it, extrapolates Spectacular Painting and Arch Destruction, and develops the Southern Cloud Sacred Body so weaker cultivators can execute related techniques. The blade therefore becomes both a weapon and a source from which a broader inheritance is derived. (Chapters 1074 and 1139)

When the Undying Underworld Emperor returns, the blade's oath becomes an active burden. Southern Cloud King still holds the weapon, but the surviving passages do not show its direct attack mechanics, a transfer, destruction, or later loss. (Chapter 1193)

Abilities and properties

• Combat amplification: The blade raises Southern Cloud King's stated output from at most ninth-level power without the treasure to tenth-level power with it. This is item-assisted strength, not an intrinsic realm advancement. (Chapter 1074)
• Top-graded rarity: Other Cosmos Gods envy such treasures, which are exceptionally difficult to acquire without the aid or scheme of an unparalleled existence. (Chapter 1133)
• Comprehension medium: Thorough study lets the king form a personal killing move and derive multiple Southern Cloud techniques. The brief does not preserve the blade's activation, range, damage type, energy cost, or counters. (Chapter 1139)
• Oath condition: Acquisition is inseparable from an oath of discipleship and service to the blade's owner, creating a spiritual and political cost beyond combat use. (Chapters 1122 and 1193)
