Chapter 691: Large Shadow Under The Water

Grey could only grit his teeth as he jumped back into the battle. 

Klaus followed behind him as well. 

Boom! Bang! Bam! 

They continued fighting against the Bunny, and as usual, Grey and Klaus were beaten brutally by it. 

Two minutes later. 

Thud! 

Grey and Klaus could barely stand after crashing into the wall once again. They've created so many craters in the wall that it almost looked like they were following a certain pattern. One thing that was worth mentioning was that they never slammed into any position twice. The Bunny also knew the dangers of causing a hole in the tunnel, so it made sure not to send them flying in the same direction. 

Grey and Klaus were on their knees panting for air. They exchanged looks and they could see the frustration and terror in each others' eyes. 

They've managed to at least cause the Bunny some harm, but compared to their current state, it didn't seem worth it.
