"The Crystal Great Demon Emperor's own strength is truly too immense," said Tang San, "And so, even a copy cannot endure all her original power; therefore, she must seal away her power. Gradually releasing it, whenever the copy's tolerance grows stronger, she releases some more. Eventually, once the copy is fully grown, she can truly be reborn. Am I right?"
"In the end, she did not choose you but chose Jingjing instead. She realized that in order for the copy to fully bear her power, its body couldn't be formed as a whole at once but needed the ability to grow. Thus, it had to start from an egg, just like she was born three thousand years ago. This is the reason why Jingjing followed me, silently absorbing the energy I provided. What she absorbed wasn't much, not meant to enhance herself but just for bodily growth, to withstand the sealed power. Am I right?"
