There were many things that he did not understand. One of them was why she decided to answer his question. This was her personal matter and also the humiliation that she endured for the past ten thousand years. How can a girl tell such things to a boy whom she just met?
Although it was Ye Xiao who asked her this question, if she wanted, she would not have answered him. But she did tell him everything and it was in detail.
Now, Ye Xiao wanted to know "why?", and he need not to as Xue Xiaofei once again started to say, "Well, the time does not exist inside the coffin and one can use it to preserve their lives for countless years. No matter how one sleeps inside, whenever they wake up, they will find themselves in the same condition when they went to sleep inside the coffin. It is indeed a very rare treasure but to use it, one has to pay a certain price."
