Chapter 290: Evolution Cube Transformation 1

With the addition of the mechanical overlord, the southern city wall was stabilized.

Within the city, Tracy was currently killing the beasts. He believed that it wouldn't be long before he would be able to kill all the beasts in the city.

So far, the camp's defense was barely stable.

At this moment, a terrifying roar came from the sky, followed by a wail.

Everyone's expression changed as they looked up at the sky.

A huge lizard fell from the sky and landed heavily on the hill outside the southern city wall, smashing a deep pit in the hill.

Lu Yuan and Si Tingxue looked warily in the direction of the deep pit. They only heaved a sigh of relief after confirming that they could not sense any aura.

At this moment, Lu Yuan's expression changed. He felt a powerful and unknown aura merge into his body. His body felt cool, as if every cell in his body was jumping for joy.

Meanwhile, the evolution cube flickered with a dark blue light.
