"The keel is less than 5 meters from the seabed, and there are multiple terrain undulations ahead." The sonar team made a rare report.
"Keep course and don't question my experience!" said the captain calmly.
509 was diving at high speed near the pitch-black seabed. At a constant speed, no one could feel the submarine's movement. Only the occasional sound of water and the ever-changing holographic sea map reminded everyone that their kinetic energy was actually quite large.
At this speed, even the slightest collision could lead to devastating consequences. The helmsman's hands were covered in sweat. Even though the submarine was being operated by artificial intelligence, he felt very nervous.
25 minutes later, the head of the submarine touched the edge of the high-density water mass. The increased buoyancy caused the submarine to vibrate, and Jiang Ling felt the floor tilting backwards.
"Attention sonar room, immediately release the active sonar at the bow at a 30-degree angle forward, with a little more force, to scare it!" the captain suddenly ordered.
With a "boom" sound, high-frequency ultrasonic waves rushed around in the water mass, and a more precise model was quickly outlined on the holographic chart.
The Hollow was lying directly above and in front of them, and upon hearing the noise, it immediately reacted, attempting to move away from 509. Its inexperience was insufficient, and its erratic movements created a large amount of wake, which exposed its position to passive sonar detection.
"Target bearing 082, relative bearing 005, depth 250, speed 5 knots, accelerating, range 8 chains."
"Hold steady! Helmsman, aim at it! Don't let it get away." Captain Yu began counting down, and then at some point, he suddenly shouted, "Emergency drain the forward ballast tank, overload the engine room, prepare for impact!"
Almost immediately, the submarine tilted upwards by 50 degrees, and all those who had not secured themselves were tripped by the sudden acceleration, even though the ground was covered with non-slip layer. A few seconds later, a teeth-grinding crash was heard from the front lower part of the submarine, but the damage control team reported that the bow of F2 and F3 was slightly damaged.
After the vibration subsided, the captain ordered the ballast tank to balance automatically, the engine room was slowed down to 2 knots, the course was restored to the established route, and the depth was marked to about 200 meters underwater.
When everyone recovered, they saw a pitiful animal dissected open on the holographic chart. It was nearly bisected, its spine broken in two. A large amount of blood mixed with its internal organs spurted from the wound into the icy sea.
It was already unconscious at this time, and the huge wound made it unable to even wail, and it would soon face the eternal end.
The mutant never dreamed that the price of its playfulness would be a 65-meter-long blade! The "7"-shaped saber left it no chance, washing away the original filth with its blood, and then, in the noisy turbulence, it sped away.
