His Past With the Heavenly Emperor (End of Vol. 8)
"So the Mirror of Darkness belonged to that dog for the Heavenly Emperor, huh."
Su Yang calmly digested all of this information after listening to Tang Lingxi's explanation.
"It's no wonder why it looked so familiar to me. I have seen it before."
"You have finally recalled?" Tang Lingxi asked him.
He nodded and spoke, "The Mirror of Darkness is actually called the Silver Dimension Gate, and it is a Divine-grade treasure that has the ability to transport one to anywhere they have been to before. For example, if I use the Silver Dimension Gate, I can return to the Eastern Continent instantly, but I cannot go to the Western Continent, as I have never been to that place."
"How do you know about something like this?" Tang Lingxi raised her eyebrows.
"I have been to the Celestial Palace before, and I was even inside the treasury briefly." Su Yang said with a nostalgic expression.
