I'll Just Catch a Fish, and You'll Send an Aircraft Carrier Formation to Chase Me?

Qin Yu, the time traveler, obtained a god-level fishing system. One day while fishing, I accidentally caught Yingjiang's sonar. "Sonar has no copper and is useless for fishing!" On the turbulent water, the furious foreigners shouted to Qin Yu through the loudspeaker. Congratulations to the host, you have caught a sonar and will be rewarded with the skill of crossing the river with a reed. "Haha, what I want is not copper!" "Hey, demon spirit? I caught..." Qin Yu called the police and turned it in, officially starting his career as a fisherman. Catching a foreign unmanned underwater vehicle will reward you with electromagnetic gun blueprints. Catch the foreign signal transmitter, reward: an island. Caught, eh? A foreign female officer? Reward... Seeing Qin Yu constantly fishing away marine equipment, the foreign navy could not bear it. "Let the aircraft carrier formation chase that kid for me!!" Looking at the menacing aircraft carrier fleet, Qin Yu said in shock: "I'll just catch a fish, and you'll send an aircraft carrier formation to chase me?"
