Sure enough, under the continuous bombardment of the Source City, fragments of the Source Principle were sensed by Ding Huan's Dao thoughts and intentions.
This time, Ding Huan did not rely on the Great Universe Technique, but instead sensed the Source Principle through his own understanding of the Great Dao.
Every time the sensing weakened, the Source City would blast out fragments of the Source Principle.
In just one year, Ding Huan completely understood what the Source Principle was, even effortlessly deriving his first personal Source Principle, the Life Source Principle.
Logically, the Life Source Principle is relatively difficult to derive, but Ding Huan possesses the Life Tree, and there is also a Life Source Principle here.
Thus, the first Source Principle he derived was not an attribute Source Principle, but a Life Source Principle.
At this step, if Ding Huan wills, he could easily refine the process of deriving Source Principles to his Great Universe Technique.
