"Oh, and how do you know this?" Di Tian raised a brow.
Yi Rui turned to Imperial Preceptor Xi, who brought out a beast skin with sketchings all over it and said, "The Dynasty has a Cosmic Observatory Unit which has some of the best diviners on the planet. Unfortunately, they didn't give us anything concrete to work with when we discovered the problem and tasked them to decipher a solution. But we recently received this from them." Imperial Preceptor Xi handed the beast skin to Di Tian. "You may see for yourself."
Di Tian collected the beast skin and looked at it. His eyes twitched, "Oh?"
On the goatskin, there was a sketched pictogram, split into three parts.
The first one showed a scene in which Royal Burial Grounds was burning with black flames and had undead creatures crawling out of it. The second was a close-up scene of someone entering it, and the third was another sketch of the Royal Burial Ground, now back to normal.
