As the deep sound echoed, all the officers and sailors aboard the Wujiang, including Ran Wenqiang, were startled.
The sound came from the west, from the direction of the military port.
However, Ran Wenqiang quickly made an accurate judgment, that it was the irregular sound of explosions, not the thumping sound emitted by active submarine sonar.
Evidently, the troops left behind had already detonated the explosives, beginning to destroy the infrastructure inside the port.
As for the naval mines that had been laid, they were all activated via remote control, that is, by sending an electronic signal that enabled the fuses on the mines to enter working state.
Of course, this was also the signal to start the war.
