It did not take long for Tang Yin to make up his mind. In the end, he decided to use the Spirit Qi devoured from the Heaven Ascension Peak to refine his body.
Technically he had already done this when his body went through a refining process after he devoured the eye of an ancient cultivator. However, back then, he had only done it subconsciously in a hurry so he could avoid wasting the energy and vitality contained inside the eye.
Now he was going to try using the Spirit Qi to refine his body, this time he was going to put full effort into it.
As the endless Spirit Qi surged into his body, Tang Yin controlled the Heaven Devouring Abyss to channel the Spirit Qi throughout his body. This was similar to how a cultivator advanced their cultivation in the Physique Transformation Realm.
The feeling of having Spirit Qi channel throughout his whole body was invigorating. However, this feeling did not last long as the Spirit Qi seeped into his flesh and bones.
