Chapter 59: Mother-child Stone

With each strike of the alloy chisel, layers of the outer stone skin peeled off.

Gradually, a dark color appeared in Lin Zhen's eyes.

"Mother-child Stone! It's actually a Mother-child Stone!" Even with Lin Zhen's vast knowledge, he couldn't help but get excited at this moment.

A Mother-child Stone is a stone that contains two Dark Energy Stones, one large and one small, hence the name Mother-child Stone.

These stones are extremely rare. Compared to the child stone, the energy in the mother stone is more pure, and much larger.

Based on the size of the stone just now and the part exposed now, there's no doubt that the previously revealed one was the child stone, while this one is the mother stone.

Lin Zhen carefully spent about three hours before finally revealing the true face of the mother stone.

If the previous one was the size of a goose egg, then this one was almost the size of a small ball, more than seven or eight times larger!
