They talked a long time, but naturally, they had to mention Mu Tongtong. This little girl was diagnosed with an Innate Poison shortly after she was born—a truly lethal poison, carried from the womb, ensuring she would not live past ten years old!
Therefore, after only a few years of eating plain rice, she was sealed by the Temporal Origin Liquid, waiting for the Creation King of the Elf Race to find a cure. Unfortunately, a great war in the Immortal Realm ensued, and the Creation King perished. Under the seal of Temporal Origin Liquid, the little girl traveled through a million years!
As for what the Elf Empress' bloodline was, little Tongtong was utterly clueless, and Huo Tian, who had initially mentioned it, forgot about it after saying it once and could not offer any explanation either.
Of course, that's not the point!
