Upon seeing the Mother of Sun's reaction, Ji Changsheng knew that it was a done deal.
A good position is like AIDS, shared only through mother-child, blood, and yin-and-yang union.
Demon Emperor is not an easy position, you have to fight for it, that's why Di Jun is relentless, Tai Yi is strong, and Emperor Fuxi and Empress Nuwa are the apex predators on the food chain.
But Demon Queen is a good position, which requires not capability, but a combination of yin and yang.
The Golden Crow Prince is also a desirable position, requiring maternal-child connection rather than ability.
So, the Golden Crow Prince died cleanly and neatly.
And the Mother of Sun completely believed in her best friend's words.
In the end they did not ascend to their positions on their own strengths.
The real skill is on the part of Di Jun who, even after losing nine sons, could still think calmly.
