Chapter 470: Storm Mode, the Old Chief's Choice

Just as the frigate was about to harvest the giant monster's corpse, a loud bang suddenly rang out from below the frigate!

Boom!

"Oh, no! Retreat quickly!"

At this moment, the temporary commander on the frigate was stunned. Such a strong vibration and movement undoubtedly meant that the frigate had been attacked by the monsters at the bottom of the sea.

"How is this happening? Why didn't the nuclear submarine find them?"

Amid this confusing situation, the commander-in-chief, Niu Honggang, wasted no time in ordering a nuclear submarine to rush to the scene. He needed it to eliminate the monster that was threatening the frigate.

However, just five minutes later, the nuclear submarine issued a danger alert!
