After returning, Jiang Cheng stayed in the Quiet Chamber refining the Speed's Profound Pattern for more than a month.
When the Speed's Profound Pattern was cultivated to the Fifth Layer, the Azure Dragon pattern on the Profound Pattern could already detach from the Profound Essence and act on its own.
This gave Cang Ling an alternative 'activity carrier'.
Although this carrier looked like a two-dimensional paper dragon...
And when the Profound Pattern reached the Sixth Layer, this former Empress could already wield a part of the Power of Speed.
But because Brother Cheng's Profound Power Realm was low, and the power of his Profound Essence was too weak, this power was also very feeble.
When the Seventh Layer was finally achieved, an image of the Heart of Speed from the Immortal Realm unexpectedly appeared in Jiang Cheng's mind.
That image was not an illusion, but actually existed.
