Eternity Pearl(定颜珠):
In Chinese, it is pronounced as: dìng yán zhū，Written as:

The Eternity Pearl is a magical bead that preserves the deceased’s appearance unchanged. It is a treasure found in “Journey to the West” and has appeared twice in the original text:
1. The King of Wuji Country was thrown into a well by a Guai, and it was the Dragon King of the Crystal Palace who used the Eternity Pearl to fix the king’s appearance.
2. When the Dragon King at Hongjiang encountered the corpse of Guangrui, he used the Eternity Pearl to preserve it, maintaining the body for future resurrection.
In the video game “Black Myth: Wukong,” the Eternity Pearl has a special function that ensures the deceased’s body does not decay. Users include Zhu Bajie’s lover, Violet Spider. After Violet Spider’s death, Zhu Bajie placed the Eternity Pearl beside her to preserve her body, facilitating future resurrection. Thus, players in “Black Myth: Wukong” are advised not to take this Eternity Pearl, as it might disrupt the preservation of Violet Spider’s body, preventing her resurrection and causing players to feel guilty.
Additionally, the Eternity Pearl has historical records. For instance, inside the tomb of Empress Dowager Cixi, there was an Eternity Pearl, referred to as the Night Illuminating Pearl, valued at 10.8 million taels of silver. The TV series “The Great Tomb Robbers” meticulously depicted the value of this pearl and its theft from the Eastern Mausoleum.
