Demon realm
The men was Yan Luo, the ruler of Netherlands. He was kind enough to give Ah Xian a half pershied soul. The soul will disappear if Ah Xian's horn is shown.
Ah Xian was able to put the soul in to the egg. The dead body, eggs ashes and his horn with half perished soul transformed in to a egg.
It took the egg to cultivate it's human form more than millions years. But it was not able to age or have a normal human life.
In that moment, Ah Xian took the egg in his arm and lost consciousness, but when he woke up he didn't even recognise the egg or anything about Yun Ling.
It was nothing but an illusion to eyes.
"How long are you going to lie yourself, Ah Xian?"
"Fu Sheng…."
With red eyes, ashes of Fu Sheng in his hand are disappearing too. He lifted his head up.
"I won't forgive you, Yun Ling."
Yun Ling's eyes filled with tears, she forced herself to laugh.
