Zheng Guandong completely released the seal of the "Thirteen Constraints," fully unsealing the holy sword "Sword of Promised Victory" and allowing this divine weapon, an EX-rank Noble Phantasm, to shine with its rightful brilliance!
However, Zheng Guandong was not Artoria Pendragon, the King of Knights, nor was he the master of the "Sword of Promised Victory." Yet, by relying on the connection between his own holy sword projection and the original, he paid an enormous price to cross the boundary of not being the holy sword's owner and forcibly unsealed the "Sword of Promised Victory" beyond his rank. Once the original was unsealed, the holy sword projection that had been sleeping within his cosmos awakened as well!
And that was what Zheng Guandong had wanted!
The holy sword "Sword of Promised Victory" was a divine weapon crystallized from humanity's faith, so its power was naturally terrifying. The name EX signified surpassing limits—it transcended the limitations of Noble Phantasm ranks and stood alone as an overwhelmingly powerful existence. Thus, even Artoria Pendragon as Saber had to abide by the rules when using it. It had been sealed by the "Thirteen Constraints," reduced from an EX-rank Noble Phantasm to an A++-rank Noble Phantasm. To restore its full power, one had to remove the seal of the "Thirteen Constraints," just as Zheng Guandong had done.
But since this seal could suppress and restrict the power of the "Sword of Promised Victory," lowering it from EX rank to A++ rank, the "Thirteen Constraints" naturally could not be casually lifted. Zheng Guandong had been able to forcefully unseal it beyond his rank only by spending an immense price and receiving the Main God's assistance. If Saber Artoria Pendragon—the former King of Knights—wanted to release it herself, the difficulty would likewise not be low, perhaps even
