The dark mines are decorated like a starry night sky.

Looks stunning!

Zhang Yang stepped forward and observed carefully, it turned out that these colorful light spots were all large and small energy crystals exposed outside the rock wall.

Moreover, the mineral deposits were so rich that Zhang Yang was overjoyed.

Just when you first enter the mine, there are hundreds of energy crystals, large and small.

As the perceptual exploration of mental power continues to deepen.

The intricate and winding mine was also presented in Zhang Yang's mind bit by bit.

Conservative estimate.

The energy crystal contained in the entire natural mine is at least dozens of tons!

"Although this mine has been visited by several beast kings first, the mining efficiency of the ferocious beasts is so low that it is almost negligible. The energy crystals dug out in the past few days are less than one-tenth of the entire mine.

.”

"In other words, the remaining fifty or sixty tons of energy crystals are all mine!"
Chapter completed!
