Chapter 664: Chapter 378: Start the Bombing Plan_1

```

Boom boom boom!

Huge boulders fell from the sky at high speed, smashing into the midst of the Mutated Creature Army below.

This scene was like a missile unit suddenly joining the battlefield.

And even if a real missile unit were to join, it wouldn't have as many continuous missiles as this.

It took Ye Feng 10 minutes to conclude the battle above, which meant that the bombardment lasted for a full 10 hours.

Eventually, the bombardment directly thwarted the offensive.

Of course, in the process, it was difficult for Ye Feng to prevent these Mutated Flying Beasts from crossing the Thunder Pool by even a step.

Out of the 3,000+ Mutated Flying Beasts, still 12 managed to scatter and, taking advantage of Ye Feng's inattention, crossed the Air Domain of the city wall.

In other words, even if they were killed, it was impossible to stop these boulders from falling onto the camp below.
