This was the fourth level of the Core Formation Tier, Core Formation.
The so-called core formation was the liquefying of the Celestial Core.. This was a very long process, and could not possibly be accomplished overnight. However, he only had to take the first small step, and his strength would soar greatly.
Come on then.
Ling Han used his mystical power to grind the Celestial Core, trying his best to liquefy it.
However, the Celestial Core was the sturdiest existence in a cultivator's body in the first place. If it really came to it, it could still be thrown out as a Spiritual Power Celestial Tool, and Ling Han's Celestial Core was formed based on the primitive Celestial Gate, so it was even sturdier.
The Celestial Cauldrons could still crash into each other and have them self-destruct each other, but there was only one Celestial Core, so what could he do?
The level of mystical power was too low, so attacking it would have no effect at all.
