Condensing a Golden Core

Half a month later, the sacrificial exercise was completed.

The eyes of the two skeletons ignited with cold blue soul flames, and their bodies constantly emitted bone-piercing cold air.

The white bones were like ice crystals, like a work of art.

When they were alive, they were at the sixth and fourth level of Foundation Establishment, respectively. However, after being refined into bone slaves, they could only unleash the strength of the first level of Foundation Establishment.

"Kakakakakaka…"

Under Zhang Chen's control, the two skeletons moved and attacked a big tree outside the cave.

"Boom!"

With a loud bang, wood chips flew and the tree fell to the ground. The entire tree was covered in frost, and the leaves were all frozen into ice.

In terms of attack and defense, the two skeletons were far inferior to the White Bone True Body. The only thing worthy of praise was the ice attribute.
