There were countless buildings and defensive facilities of the ancient Dragon Empire, and many of them were things that Li Cheng had seen before.
However, the buildings here were clearly usable. Within this strange building, there was a surging and terrifying energy.
Li Cheng did not hesitate. He immediately ordered all the troops to focus their fire to destroy these defensive facilities.
Immediately, countless terrifying explosions were heard. A dazzling light illuminated the entire underground space.
Roar!!!
Roar!!!
Countless furious dragon roars resounded throughout the entire cave. Those Black Dragons clearly did not expect that Li Cheng would actually be able to ignore their defensive line and enter the deepest part of the lair.
At the same time, the system's voice continuously rang in Li Cheng's ears.
