If Yi Yun had directly used the Purple Crystal to absorb a complete herb, it would easily gain the attention and arouse the suspicions of the Tai Ah Divine City alchemists.
But in the current situation, the Heaven Purple Yang Ginseng had suffered serious damages. Yi Yun was only absorbing the escaping herbal essence, which would not lead to any suspicion.
Of course, Yi Yun could only do this occasionally. He could not always bring back herbs that were seriously damaged. Besides, damaged herbs would greatly reduce their value, and the compensation in dragon scale runes paid out by the Tai Ah Divine City would be less.
In conclusion, it was not very beneficial to Yi Yun.
Under the Purple Crystal's control, none of the herbal essences of the Heaven Purple Yang Ginseng was wasted as it was all absorbed by Yi Yun. The energy that gathered into light dots were like dancing pixies.
