BOOM, BOOM, BOOM.
The sounds of cannon fire and officers clashing reverberated across the heavens and earth.
Wang Yan, after chatting briefly with the general, also joined the battle. His Spirit spread into every corner, ready to react to any danger instantaneously. For some Fourth Rank Mutant Beasts, he even intentionally left them with a breath of life, allowing the officers behind him to enhance their combat skills.
"Everyone, fall back."
After felling a Fifth Rank Mutant Beast with a few punches and sensing something from the tunnel, Wang Yan suddenly spoke gravely.
Upon hearing the command, the officers behind him quickly retreated, creating a large, clear area. Cannons were aimed at the tunnel entrance, missiles at the ready.
"BOOM!"
A sound of rending air echoed from the tunnel.
A terrifying aura, breaking the sound barrier.
A missile fired instantly, heading straight for the Sixth Rank Mutant Beast that burst out.
"RUMBLE."
