Flames suddenly rose from the dense flock of birds, and a huge sound swept down. Wang Xiao instantly realized that something was wrong, but it was already too late when he wanted to remind them.
The first red bird that exploded was like a fuse. Before the flames it ignited were extinguished, the second red bird also exploded!
Boom! Boom! Boom!
Huge explosions continuously sounded, especially in this sealed environment. Countless echoes overlapped, simply deafening!
Wang Xiao had already blocked his ears with all his might, but his eardrums were still hurting from the explosion. Everything around him was shaking violently. He even suspected that this fortress would collapse and directly bury them alive!
Fortunately, this fortress was stronger than Wang Xiao had imagined.
