Emperor Demon Underground Palace, is the burial place for emperors and empresses of the Emperor Demon Clan over countless millennia.
The emperors before Emperor Demon Wu Ya were all buried here.
Emperor Demon Wu Ya perished by destroying his Primordial Spirit. Yue Jinghua needed to enter the underground palace to find the Emperor Coffin sealing Ying Wuyou, but before that, she had to enter the underground palace.
The entrance to the underground palace is right beside the Chaos Well.
Following Hong Lei's directions, Yue Jinghua found the Chaos Well deep within the Emperor Demon Palace. She placed Emperor Demon Wuyou's body into Mo Xi's Sea of Consciousness, using the spirit power of the Star Sea to nourish the Emperor Demon body.
To enter the Chaos Well smoothly, Emperor Demon Blood is needed as a guide.
In Yue Jinghua's hand was the jade token left to her by Ying Wuyou, containing a drop of mixed heart blood from Emperor Demon Wu Ya and Ying Wuyou.
