In the novel, Ange stabbed Pearl, but it was not fatal. Later saved him, but left the root of the disease, which is also an important reason for Pearl's serious illness and death.
An Qingxu can promise Pearl two conditions, but only if she can't leave.
Therefore, Pearl first asked Brother An to let Shengfeng dress them, and then let him commit suicide.
An Qingxu can give up everything for Pearl, but he can't do everything. He doesn't have this ability in troubled times. He was trapped by his father. More than that, Dugu Jingyao took the pearl and he still had a chance to get it back, but it was also because of military needs.
The pearl died in his hands. Finally, the husband and wife reunited, and the children were killed by pearls and lived a better life. As a result, because of this serious injury, Aner took single dog's anger to get back at the man in advance, and he was destroyed a few years later.
