"I don't know either." Jialan shook her head. As one of the top five outstanding disciples of the Yuhua Sect, she didn't know the origin of the Heavenly Emperor's Mirror, and Fang Qingxue also indicated that she didn't know.
As for Long Xuan and the rest of the true legacy female disciples, it was even less likely that they would know.
"The Heavenly Emperor's Mirror is one of the three treasures of the Ancient Three Emperors. In ancient times, when the World Tree still existed, there were three emperors in the Profound Yellow Great World. The first one was the Heavenly Emperor, the second was the Earth Emperor, and the third was the Human Emperor. They were all extremely powerful beings who each held a magical treasure respectively - the Heavenly Emperor's Mirror, the Earth Emperor's Book, and the Human Emperor's Pen. They were incredibly powerful and were Immortal Tools!" Yan spoke at this moment.
