Crystal

Even if the crystal that had fallen into the planet's core was ancient and warped by its surroundings, Hao Ren was very sure that the crystals were the very same ones he saw in that illusion.

It was not too long after Vivian managed to control the power of the Crimson Moon either. Hao Ren had embarked on a search on the moon itself and found an enormous stash of mysterious crystals at the bottom of the Crimson Moon ocean. After he came into contact with the crystal, he fell into another illusion left behind by the goddess of creation. In that world, Hao Ren saw a mysterious planet covered in a storm of lightning, and the planet's surface was filled with a bluish-white crystal...

Lily was the first to react to what Hao Ren said. "Whoaaa!! Mr. Landlord, you sure it's the same thing?"
