Back in the Beast Realm

After coming back, Alex had done a few testing on himself. 

After merging with the yin orb, he needed to know if his body was still capable of doing what it used to do before.

The first thing he tested was if he could create Yin and Yang separately now that they were coming out in a fused form.

Alex realized that he could easily pull out yang and quickly fill his whole body with it if required. 

As for Yin, it wouldn't come out unless he started circulating the Winter Moon technique. 

He found his yin to be much better than before, and his only Yin technique, the Flickering Shadows technique had a much wider range and accuracy.

As such, Alex was sure that his Yin root had improved much more than he could have hoped for. However, like his Metal Qi and Yang Qi, he couldn't freely control Yin Qi outside of his body.
