The metal brain

After seeing this scene, Tang Zhen immediately kept the remains of the mechanical creature and quickly rushed toward the tunnel in front.

As he got closer, the sound of fighting could be heard, mixed with the screams of humans.

They had already reached the end of the tunnel. A brightly lit underground hall suddenly appeared before Tang Zhen's eyes!

After slowly walking into the hall, Tang Zhen saw the giant origin stone floating in the middle with a glance. His face also revealed an expression that said "as expected."

Upon closer inspection, one would realize that the giant origin stone was not complete. It was made up of many small origin stones, but under the constraint of a special force field, the many origin stones were always condensed together.

However, in that case, its value would be greatly reduced.
