It is more interesting to develop your bloodline than to use a bloodline that was created with someone else's Dao, but following the strongest direction, the Ancient Race. Another thing, the Five elements in their final phase become space-time, become anything, this is from Desolate Era that I read. He can make space-time become five elements and vice versa, that is, Chaos, Yin Yang and five elements encompass all things and are the principle of everything, another reason why I like the Dao of the Stars and that in many romances is using in conjunction with Dao of Foresight, Wisdom and Fate, so it could hinder any Dao of Fate user from knowing its details.
The five internal organs represent the five elements, so he can refine the five internal organs. The fusion of the five elements is the principle after Yin-yang and then Chaos, if he refines the five elements enough, he can create an Aura of Chaos, which he can use to refine his bones, muscles, blood and finally their divine soul, condensing their soul into a chaotic soul and fusing with their body as only, the Nunero 1 Ancient Race has a powerful physique that is completely fusing with the soul, thus they have great resistance to attacks from the Dao of the Soul.
Since you are using the stars to refine the cells, it would be interesting if you became an expert in the Dao of the Stars and the Five elements. Using the Dao of the Soul as a base, using the Dao of the Star and the Five elements to create a kind of giant Avatar that appears as if it were a martial soul to amplify techniques of the five elements and to use the Dao of the stars to imitate, the beasts Chinese divine powers, and prehistoric monsters with strange abilities such as Chaos, which devours everything.
