The 111 plant of the Third Academy of Aerospace Science and Industry developed a 4.7-meter bionic robot whale shark. If you can minimize metal materials, disguise as real sharks, plus biofuel cells, that is, you can really eat marine organisms and use marine organisms to generate electricity, which is equivalent to permanent endurance. Get hundreds of thousands, millions of or even more of these artificial fish, disguise themselves as schools of fish, and put them in the sea, spread throughout the four oceans, especially around certain empires. It can not only detect sea conditions and draw topographic maps of the seabed, but also study the marine climate, ocean currents, marine life, and marine garbage, but also detect enemy situations, track ships and submarines, pull out other people's seabed detection equipment and torpedoes, and can also be used as a communication relay. That sour, I dare not imagine.
