Why Are There Spiritual Stones on the Ground?

When the old cow was plowing in the blue farmland, Lu Chen asked in a daze: "Why... All the ground is made of spiritual stones?" The old cow stopped, tilted his head and looked at Lu Chen in confusion, and then kicked the old farmer behind him: "Plow the land well! Why are you so stunned?" He had to continue working hard. "Why?" The old farmer heard Lu Chen's question, "If the ground can't be made of spiritual stone, what else can it be made of? Is it possible to use you to make it?" After that, he continued to operate the plow and cultivated hard.
