Fu Chen came out of the cave and noticed that the main portal of the Secret Realm was already closed. But, he didn't panic. He rushed toward the exact place where he was before and released his Infinite Eyes' purple light.
This purple light was energy itself so when it struck the barrier, it condensed a portal in that exact place and sucked them inside. Fu Chen came out of the barrier and floated for a moment.
He took out the orb from his spatial ring and released his spiritual sense. After sensing that everything was fine, he decided to put the orb inside his inventory and go for the search Eternal Dragon Reverse Scale.
However, this piece of the scale was located at the Holy Paradise of Cultivation. That means he had to visit the Divine Star Kingdom before he could get his hands on the Eternal Dragon Reverse Scale.
