Great Seal
The Great Seal is the greatest secret in Ancestral Master Archean Eon's inheritance: a gray seal refined by an Eternal existence. It is both a weapon of overwhelming destruction and a second system of laws against which Meng Chuan can compare the River of Spacetime.
History
A hidden weapon becomes a cultivation cornerstone
Ancestral Master Archean Eon obtains the seal by chance and hides it in his homeworld rather than risk attracting Eighth Tribulation Eminences. After Meng Chuan survives his sixth Heavenly Tribulation, the treasure-vault guardian reveals the secret and places him in charge. Meng accepts the conditions that he neither disclose the seal nor remove it from Archean Eon Realm before reaching the Eighth Tribulation realm. He leaves an Essence Soul avatar beside it to study its structure. (Chapters 635–637)
The seal thereafter becomes a persistent reference for Meng Chuan's cultivation. He compares its destructive laws with the universe's balanced spacetime laws while studying space and Heaven Splitting. Once he grasps the complete spacetime law, he can fully restrain the seal's emissions and perceive far more of its true horror, but he still keeps it concealed in Heaven and Earth Great Hall. (Chapters 648, 675, and 744–746)
Abilities and properties
Eternal construction and destructive law
Even without an owner, the seal continually destroys the nearby void; a homeworld array restricts that emission to roughly one hundred feet. Its interior is a vast structure of interlocking laws comparable in scope to the laws of spacetime but oriented toward destruction. Contact also reveals a residual image of its bald, towering Eternal creator wielding it across an immeasurably large region. (Chapter 636)
Activation, limits, and current state
An Origins law is the minimum requirement to drive even a sliver of the seal's power. Ancestral Master Archean Eon believed that doing so let him contend with a half-step Eighth Tribulation Eminence, while Meng Chuan's later spacetime-law mastery exposes substantially more of the treasure's potential. Its greatest practical limitation is secrecy: using it outside the homeworld could draw Eighth Tribulation competitors, so it must remain inside Archean Eon Realm. A lake of dead Eighth Tribulation blood found wrapped around the seal shares that restriction but is not part of the seal itself. The Great Seal remains intact and under Meng Chuan's control at the end of the supplied corpus. (Chapters 636–637 and 744–746)
Owners and wielders
| Holder | Capacity | Source-grounded relationship to the seal |
|---|---|---|
| Unnamed Eternal existence | Creator | A residual imprint shows the Eternal wielding the gray seal and displaying its destructive reach. (Chapter 636) |
| Ancestral Master Archean Eon | Finder and former wielder | He finds the seal, conceals it in his homeworld, and uses it strongly enough to compare himself with a half-step Eighth Tribulation Eminence. (Chapters 635–636) |
| Archean Eon Realm | Custodial location | Its arrays suppress and conceal the treasure inside Heaven and Earth Great Hall. (Chapters 635–637) |
| Meng Chuan | Current controller and student | He accepts custody, studies the seal with an Essence Soul avatar, and later controls it with the complete spacetime law. (Chapters 636–637 and 744) |
