Xue Ning finally understood it, but it was because she understood it that she found it hard to believe.
In common sense, merging two souls into one was absolutely impossible, even if it was mergeable, the new soul would still break down and perish not long after.
Every being's soul had the same structure, but the elements in each soul were completely different, thereby making it impossible for two souls to become one.
Put it in a simpler term, it was like mixing vodka with gasoline. The two could be mixed together, but after mixing, the liquid could never be consumable nor usable.
But the situation before in front of her seemed to be telling her that nothing was impossible in this world. Just because she had never seen it, it did not mean that what she had never seen did not exist.
After understanding this simple fact, she calmed down completely.

Yang Song stayed still and looked at Xiang Lige's body.
Creation is hard, cheer me up!
