According to Xuanwu's records and the blind man's explanation, this was the Night Emperor's personal token, similar to a personal seal.
It did not contain any special energy or inheritances, nor could it issue orders for factions; it was merely used by the Ancient Xuanwu in charge of casting swords. Possessing this token allowed the other Four Symbols to cooperate with Xuanwu in their actions, and after the token was melted down, it could also serve as a material for sword casting.
Perhaps in the eyes of the Ancient Azure Dragon, White Tiger, and others, this token did not hold much significance. Aside from matters related to sword casting, it could not command them to act, nor could it speak on behalf of the Night Emperor.
But for believers of this epoch who were unaware of the inside story, perhaps its meaning was even more significant than an "official seal."
A personal token, huh? Doesn't that count as the meaning of "seeing this as if seeing his Majesty in person"?
