Jiang Ming was very surprised, extremely surprised at that.
He knew that Tai Yuan had three avatars. One was the Heavenly Emperor, who had fallen. As for the other two he didn't even know anything about them.
Never did he expect to see one in the Abyss and was a woman at that. No, she shouldn't be considered as a woman but should be called the body of the Saint Spirit.
Back then, Tai Yi extracted some power of origins from the Extreme Yin Stellar. He wanted to refine it into an avatar and harness the power of Taiyin, but he died on his way towards sanctifying Dao. Hence, he left the legacy to Tai Yuan.
Later on, Tai Yuan quietly condensed his avatars, and taking the origin of the stellar as the framework, he directly settled in the Extreme Yin Stellar, becoming the innate lunar spirit. He introduced it into the stellar's origin to protect himself, and comprehend the great cycle of Dao.
