A Fierce Battle

Normally, a regular soul pet's second stage of evolution would allow them to reach the rare level.

Every time it evolved, its vital structure would morph, and its species potential would be boosted.

The stronger a young soul pet's starting point was, the more durable it would be after evolution; its upper limit would be even higher.

After a soul pet hatched, it could achieve a second and third stage of evolution. Under normal circumstances, a soul pet could evolve twice.

Once it completed the second phase, its strength would definitely be enhanced greatly.

The Triangular Hard Rock.

After it underwent its second stage of evolution, its surface was covered in a layer of silver that gleamed, and its originally uneven rocky exterior became much smoother.

At the same time, there were still many edges and corners, but they looked more aggressive now.

Other than its body being enlarged, the biggest change was its shape.
