Magical Beast Troubles, Part I
Wu Jian soon discovered that helping Youmei reach the Deva Realm wasn’t going to be as simple as he originally thought. They had fed her the magical cores of the Blaze Lions, which he had expected to boost her all the way to the Deva Realm, since they were the spirit cores of Deva Realm beasts, but his expectations were met with disappointment.
Youmei barely grew at all.
She had consumed twenty spirit cores and only reached the fifth Subrealm of the Human Limit Realm.
According to Huǒ Shuchang, it was a matter of compatibility. Youmei wasn’t compatible with the Blaze Lions because they had a strong yang chi and her chi was composed primarily of yin. She only took in the yin chi and expelled most of the yang chi from her body. Of course, if that was the only problem, they could solve it by constantly feeding her more spirit cores. Wu Jian had tried to do just that.
And Youmei had gotten sick.
