"Is it done?" asked Zhou Kai from the side.
"Of course!" Lin Chuan nodded and said, "This is a signal bomb."
"But there's no fuse!" Lu Dapao looked at the bomb suspiciously, tightly sealed to prevent water leakage, wrapped with several layers of waterproof material.
"How can an underwater bomb have a fuse?" Zhou Kai laughed, "Chuanzi Ge can definitely find a way to detonate it."
"This bomb is detonated via mobile signal," Lin Chuan smiled.
"Wow!" Zhou Kai and the others exclaimed in admiration.
"Leave it to Huo Di to find a few people," Lin Chuan smiled. "There's a strong magnet inside, when their boat comes, let the frogmen attach it to the bottom of their boat."
"Alright!" Zhou Kai was thrilled.
Huo Di found five or six people with good water skills, but there were only four bombs. So, in the end, only four frogmen could execute the mission. These four frogmen sat on the speedboat at night, guarding the entrance of the necessary channel to the dock.
