Su Zijin and Gu Xiyan, while they were speaking, each took out a jade pendant that had been hanging from their necks.
The jade was Green Emperor Jadeite, exquisite and translucent with abundant water content, and had a rim of gold both along the interior and exterior parts.
This was Gold Inlaid with Jade.
Beforehand, Mu Jinyu had refurbished the Order of Slaughter for Xiang Mantang, elevating its defensive formation to a higher level. Feeling quite proud of his own knowledge in formations, he impulsively bought a large quantity of Green Emperor Jadeite.
Jade naturally contains a significant amount of spiritual energy, although it's far less than the lowest grade spirit stone. However, since Mu Jinyu couldn't get his hands on any spirit stones on Earth, he had to make do with Green Emperor Jadeite.
