From the Soul Energy Realm to the Snake-dragon Realm, the external change could be said to have changed from only being able to fly for a short period of time to being able to fly through the sky and travel through the earth.
The internal change was another qualitative change in the power of his body.
Michael speculated that in order to get the acknowledgement of the ring in his hand, it was very likely not performing a flying skill, but to make the power in his body undergo a qualitative change again.
What he needed to do was to let the true power in his body undergo a qualitative change and see if there would be any reaction from this ring.
At this moment, he was still far from the Snake-dragon Realm. Naturally, he couldn't rely on his realm to break through and undergo a qualitative change in his body's power.
Therefore, he was going to use another method.
