"I choose... Yin and Yang."
Chen Yun said softly.
This was not just intuition, but also involved some judgments he made on his own.
Although unsure if this was the correct decision, he felt that the balance and harmony between Yin and Yang might align more closely with the essential nature of the strength he sought.
After all, in 'Journey to the West,' the Roc was more skilled in wielding the Yin and Yang Qi, equipped with the protective Magic Treasure of the Yin Yang Qi Bottle.
The Five Elements were not abilities that should be associated with the concept of "Roc," but rather, they were the specialty of its relative, Mahākāla.
Clearly, a powerful evolutionary ability was leading him toward the concept of "Roc," incidentally adding a few additional patches along the way.
So, after careful consideration,
he wanted to choose Yin and Yang.
