Eternal Dark Prison

"Revenge?" Jian Wushuang looked at Demon Monarch Ancient Night in surprise.

He could tell that Demon Monarch Ancient Night absolutely hated his enemy. Otherwise, he would not be so angry.

Moreover, he could tell that the reason why Demon Monarch Ancient Night hated him so much was not because he had killed some of his closest relatives, but because he had been captured alive in Eternal Dark Prison, and he had been in his hands for a billion years.

During that billion years, Demon Monarch Ancient Night must have been tortured by him.

However, since he was so powerful that he could capture Demon Monarch Ancient Night alive, how did he escape from him in the end?

Jian Wushuang was puzzled, but he did not ask further.

"Demon Monarch Ancient Night, who is your enemy?" Jian Wushuang asked.
