Wang Feng nodded and had just found out Qin Yu had obtained a vast amount of spiritual essence.
These spiritual essences signified endless spiritual energy, and as long as there was enough spiritual essence, he could set up various powerful formations.
Some terrifying formations would consume tremendous spiritual energy each time they were activated.
For example, the Immortal Eradication Formation had to accumulate energy for a hundred years before it could be used again.
"Ji Yue, I have something to tell you."
Qin Yu turned his head to look at Ji Yue, and Sumeru qi enveloped Ji Yue. The two entered the Sumeru ring together.
"These are all things from your Jee family's ancestral space. I've already absorbed all the vital energy from dozens of spiritual energy Mystic Realms. These things should be returned to you, and you should leave a portion of your spiritual essence stones for Wang Feng to set up the formation."
