Yuki closed his eyes and connected his perception with the sonar. He could feel the three supercavitating torpedoes getting closer. Xiang Shan had told him about such situations before.
In the worst-case scenario, the enemy would entangle him and then launch torpedoes at Yuki and the others.
Xiang Shan could shoot down the torpedoes heading towards him with bullets, but he couldn't do anything about the torpedoes targeting others. Xiang Shan's bullets were kinetic weapons, and even though they were equipped with propellant, the amount that could be installed into a single bullet was extremely limited. In such an environment, they simply couldn't catch up with torpedoes aimed elsewhere.
In these circumstances, they could only rely on themselves.
Yuki had already pushed the speed to its maximum. However, there was a speed difference of over 140 knots between the vehicle and the supercavitating torpedoes.
