Since Zhang Wei has already informed the Demon Lord about the prince's revolt there was nothing much to do in the realm.
Therefore, he walked around the capitals in the hope to find some rare ingredients to forge the elixir.
From the marketplace, he bought the rarest demon spider grass, the demon beast core and went straight to the spirit stones shop.
The shop was selling various kinds of stones and crystals with spiritual energy in them. Some contain thousands of years worth of spiritual energy while some have ten thousand years worth of spiritual energy in it.
The Demon seller thrilled upon seeing the new customer welcomed him excitedly, "Mister...! These are my latest collection of the spiritual stones. If you are a cultivator, I am sure you will like it. These spiritual stones will help you a lot in your cultivation"
Zhang Wei smile at it. He then glowed his eyes and opened up his spiritual sense to sense the energy of those crystals stones.
