The tunnel in the cave extended diagonally into the depths of the Earth.

Chu Zhou quickly flew down with Dragon.

Chu Zhou appeared in a huge underground space with the Dragon about 100 meters deep.

Almost instantly, Chu Zhou was attracted by a ball of metal the size of a water tank.

The ball of metal was chaos-colored and looked like a huge heart.

On the surface, there were countless mysterious universe engravings circulating.

Most importantly, this heart-shaped metal seemed to be alive. It beat like a heart, causing the Void to tremble.

Chu Zhou seemed to see all kinds of Metal Law Profound the moment he saw the heart-shaped metal.

These Metal Law Profound were usually very difficult to comprehend.

But now, it seemed to be placed in front of him and all his secrets were revealed.
