Yu Ziqing had long wanted to emulate the similar dharma methods of the Three Divine Dynasties.
But these things have always been exclusively enjoyed by the emperor of the Divine Dynasty; even if others obtain them, they cannot practice them.
In a Divine Dynasty's power structure, what the emperor possesses is tantamount to the source code.
Whether it be courtiers or magical treasures, the authority and power derived from the Divine Dynasty are far inferior to the emperor.
Within the Divine Dynasty, this is forbidden, even the Crown Prince cannot access it.
Yu Ziqing naturally couldn't ask Emperor Zhen; regardless of whether he agrees or not, asking means you're not aware of your own standing.
Even if Emperor Zhen agrees, the favor you'd owe would be enormous.
It's the same with Dali, no need to even think about it.
As for Daqian, asking for it previously would be akin to turning against them.
Yu Ziqing had never considered borrowing it in the past.
