Chen Miao checked how much yin energy and soul power he had expended.
This single mirror had consumed a third of the yin energy in his body, but only a tenth of his soul power!
According to the Mirror Condensation Technique, the ratio of yin energy to soul power should have been one to two: one portion of yin energy to two portions of soul power. This uneven expenditure did not mean Chen Miao had practiced it incorrectly. Rather, his soul body was already far stronger than his current cultivation level warranted. A tenth of his soul power was enough to match that third of his yin energy.
The reason it required more soul power than yin energy was that the condensed mirror itself connected to the mirror space.
Previously, Mirror Pillar had brought the Ninja into the world within the mirrors not through an existing mirror, but through the mirrors condensed within the Mirror Realm. The soul power and yin energy needed to create mirrors with the Mirror Condensation Technique were a one-time expense.
As long as Chen Miao wished it, he could allow anyone to enter the world within the mirrors through a mirror he had condensed, expending only a small amount of yin energy. Of course, if he grew strong enough, he could also pull someone through an ordinary mirror.
But every entry and exit through an ordinary mirror consumed a large amount of soul power and yin energy.
In the long run, condensing mirrors was better.
Besides, the condensed mirrors could be hidden in the mirror space and summoned directly whenever needed.
That way, he would not have to start condensing them on the spot every time he fought.
However, this method had the same drawback as the mirrors Chen Miao had marked before: these condensed
