King Arthur's Thirteen Seals were Shen Fei's trump card against Goetia. Goetia, who had incinerated humanity, wanted to return to the moment before the planet's birth. He was truly an enemy of the world, enough to let the Star-Forged Holy Sword display its power.
Combined with Lion King's holy lance, which was also a star-forged armament to some extent, even if the two of them could not lift all thirteen seals, it should still be enough to destroy the Time Temple. Even temporary destruction would be enough for Shen Fei's plan to succeed.
It was just that releasing all Thirteen Constraints was extremely difficult. Otherwise, they absolutely could have shattered the Time Temple. However, accomplishing that was very hard, because some of the constraints opposed one another. Fulfilling one meant failing another.

No one in the Moon World could withstand the power of two star-forged armaments head-on, not even Tiamat, the Mother Goddess of Creation, let alone Goetia. The only reason he survived was because this was the Time Temple, which was one with him. Without destroying the Time Temple, there was no way to kill Goetia. Otherwise, this single strike would have marked the successful restoration of humanity.
