Chapter 432 Underwater Plaza

Yan Fei controlled the Drone slowly approaching the giant bubble-like object, and during this process, he discovered through the Quantum Radar that US naval submarines and destroyers occasionally passed overhead through the sea water. Submarines below the sea surface, coordinated with the towed sonar released by the destroyers above the surface, formed a perfect anti-submarine network on the seabed, preventing other countries' submarines from approaching this area.

The military strength of the United States Navy was formidable, capable of outclassing the navies of the entire world on their own, so they easily drove away other countries' warships and submarines from these territorial waters. However, the US Forces' expulsion efforts had no effect on China and Russia, whose submarines remained in these waters, determined not to leave.
