Before leaving, Zhou Wen had asked Moon Goddess what the medicine mortar looked like, but she told him that he would identify it at a glance after leaving the osmanthus forest. It would be easy to recognize it.
Now, Zhou Wen knew why he could recognize it at a glance. The white object was clearly a huge ring-shaped mountain. Moon Goddess had actually called it a medicine mortar.
Zhou Wen knew that he wasn't mistaken because the surrounding ring-shaped mountains were all gray. Only this one was white and looked especially striking.
According to what Zhou Wen knew, many of the ring-shaped mountains on the moon were formed from meteorites, but this white ring-shaped mountain looked somewhat special.
As the mountain wall of the ring-shaped mountain wasn't very tall—only about two to three hundred meters—the Great Might Vajra Bull leaped up and arrived at the edge of the ring-shaped mountain, allowing him to look inside.
