Chapter 639: Spiritual Stone

Guo Yuyun said, "The former Sect Leader of Heavenly City Sect used spiritual stones to deal with demons and ended up blowing himself up with no remains left because he lost control."

Cold sweat broke out all over Ye Chen.

Guo Yuyun gave a cold smile, looked at him, and said, "And you called me impulsive, I think you are more impulsive than me. You weren't so hotheaded before. I think you drank yourself silly, and you accuse me of being drunk."

Ye Chen gave a faint smile.

Rong'er said, "What should we do, it's so hard to deal with, it might explode, and we might end up blowing ourselves to pieces."

Guo Yuyun asked in confusion, "When did the spiritual stones of the Central Plains come to the Wastelands?"

Ye Chen suddenly started to wonder and asked, "Is there a difference between the spiritual stone and the heart stone?"
