Three Fire Prison Realms Cauldron

The Three Fire Prison Realms Cauldron is a training prison refined by Yuan and hidden in Monarch Nine Cloud's treasure cove. Its three nested worlds hold the Myriad Tentacles Dragon Son, an innate Chaotic Origin creature whose overwhelming attacks and body inscriptions give peak Cosmos Gods a protected opportunity to temper their combat techniques. (Chapters 1145–1148 and 1156)

History

Monarch Nine Cloud's hidden cauldron

Xue Ying finds the cauldron while investigating Monarch Nine Cloud's treasure cove, motivated by the Sacred Master's intense desire for an object whose secrets even Monarch Nine Cloud could not unveil. Xue Ying can penetrate the cove's concealment because his Dao of Void has surpassed its creator's hiding method, but discovery does not give him control of the treasure itself. (Chapters 1145–1146)

Entering the prison worlds

Inside, Xue Ying perceives three spherical worlds nested one within another. The outer and inner layers appear empty, while the core contains a terrifying distant aura; a gale he encounters reaches approximately level-three Cosmos God power. He cannot clearly sense or activate the interior because the cauldron is not meant to become his possession. When his avatar approaches death, a cheerful red-robed treasure spirit sends him out and identifies itself as the spirit of the cauldron. (Chapters 1147–1148)

Yuan's training prison

The treasure spirit explains that Yuan refined the cauldron specifically to imprison the Myriad Tentacles Dragon Son. Local cultivators cannot control it because releasing the creature would allow it to destroy every living being in the Origin World. Instead, peak Cosmos Gods with sufficient comprehension of Chaotic Origin Energy can enter to fight the prisoner while the spirit watches and ejects them immediately before death. Xue Ying activates the opportunity early because of his supreme secret impartation, and the spirit warns him not to let the creature's profound mysteries distract him from reaching the final realm. (Chapter 1148)

Repeated tempering

Xue Ying subsequently sends avatars into the cauldron frequently. The Dragon Son's tentacles combine mysteries of the Void, Flames, Lightning, Mirage and Illusory Realm, and other Daos, while each casual strike rivals an unparalleled existence's full-powered attack. These battles expose weaknesses in Xue Ying's defense and technique, giving him a rare opponent capable of pressuring him without permanently endangering his other avatars. (Chapters 1147–1148 and 1156)

Abilities and properties

• Three nested worlds: The interior consists of three spherical layers, creating a prison structure far larger and more complex than the exterior vessel. (Chapter 1147)
• Lethal environment: A gale reaches roughly level-three Cosmos God power, and the core radiates enough danger to frighten Xue Ying from a great distance. (Chapter 1147)
• Chaotic Origin confinement: The cauldron holds Myriad Tentacles Dragon Son, preventing an innate Chaotic Origin creature from escaping into the Origin World while still permitting controlled combat against it. (Chapters 1147–1148 and 1156)
• Independent treasure spirit: A red-robed spirit serving Yuan observes every visitor, controls entry and exit, and ejects a cultivator immediately before a fatal blow. This safeguard makes otherwise lethal training repeatable. (Chapter 1148)
• Combat and comprehension training: The Dragon Son's body manifests multiple Daos in a unified natural form. Studying its movements and enduring its attacks helps qualified cultivators discover weaknesses, refine defenses, and deepen their realm through battle. (Chapters 1147–1148)
• Control limitation: Physical access is not ownership. Yuan prevents local cultivators from mastering the cauldron because control could release the prisoner and doom the Origin World. (Chapter 1148)
