Near midnight, on an aviation aircraft carrier of the advance fleet of country A, in the control room of the unmanned submarine, only three or four sailors were sitting in the seats of more than a dozen people, controlling the three unmanned submarines, and several other people were gathering around the coffee machine next to them to celebrate their major's birthday and cut the cake. A large display shows the latest analysis data and sonar simulation environment map from the flagship carrier's datalink, a 'school of small fish' and some large fish are cruising below the fleet, the submarine's detection equipment and high-definition cameras with spotlights have not found any suspicious objects, and the sailors, who have been working intensely for many days, have decided to seize the time to relax in order to adjust their highly tense nerves and have a late night snack by the way.

As soon as the major put a piece of cut cake in his mouth, one of the operators of the unmanned submarine suddenly shouted: "Major, come here, I don't know what the fault is, my submarine suddenly lost control, the pressure in the cabin rose sharply, it seemed to be leaking, as if it had been sinking." Immediately after the operators of the other two unmanned submarines also said that the same problem occurred, the major immediately panicked, hurriedly spit out the half cake in his mouth back to his plate, staring at several sets of constantly scrolling data on the screen to look for possible problems, but except for the constantly updated submarine depth, there was no other problem in the data and the picture transmitted back by the submarine. The major knows that the average sea depth in this sea area is 1,200 meters, and if it sinks at this speed, the unmanned submarine will soon be out of control, and the equipment will be scrapped because it exceeds the design depth, because these unmanned reconnaissance submarines are not designed for deep-sea exploration, but only for shallow sea escort patrols. The major came to the console of an operator, tapped the keyboard a few times very skillfully, and adjusted a few operating knobs, but the unmanned submarine still did not respond and plunged into the deep sea without hesitation.

Looking at the submarine signal that gradually disappeared from the screen, beads of sweat the size of soybean grains oozed from the door of the major's head, and he knew that there must be an emergency, and decided to report the matter to the commander of the advance fleet immediately.

************************************************************

Gong Qingguo and his Hummingbird commando team quietly stopped on a solid seabed, watching the progress of the various teams that started the operation from the screen, and when several modified MSI Hummingbird A-20s responsible for clearing the unmanned submarines successfully cut the three unmanned submarines apart, Gong Qingguo knew that he was only a stone's throw away from the final goal.

The "schools of fish" began to disperse, splitting into two smaller "schools of fish" and swimming towards their respective huge carrier targets.

The advance fleet is composed of two new aircraft carrier battle groups, in order to strengthen the defense of the surrounding waters and facilitate maneuvering, the fleet adopts a battle formation that is often used, the two aircraft carriers are basically neck to neck, all kinds of combat ships and supply ships are covering around, there is only a distance of one nautical mile between the two aircraft carriers, several unmanned aerial vehicles are constantly patrolling over the aircraft carrier, and a new type of early warning aircraft at high altitude provides long-range air warning and combat command for the fleet under the cover of three escorted F-48B, The four military satellites in orbit are also operating in the bottom orbit of space overhead at this time, monitoring all the movements around them, and the layout of the integrated battle of sea, air and space can be said to have been evolved to the extreme.

The twenty Hummingbird A-20s of the first attack group have approached the huge bottom of one aircraft carrier, and the other twenty Hummingbird A-30s have formed a protective barrier around them, because they have reached the bottom of the aircraft carrier, and the hummingbirds no longer need to worry about the possibility of detection, because the aircraft carrier itself is now the largest shield.

The forty hummingbirds of the second attack group were also rapidly approaching the target, Gong Qingguo was still nervously staring at the positions of each group displayed on the screen, and Ouyang Rongguang next to him reminded him that he should also pay attention to the situation of the opponent's fleet, because the unmanned submarines had all sunk, and the other party should have response measures soon.

Sure enough, the fleet's advance suddenly slowed down, and the escort combat ships were gradually approaching the aircraft carrier, and at this time, the hummingbirds of the attack group had all reached the predetermined position, and were walking with the aircraft carrier at the bottom of the aircraft carrier at the same speed. Gong Qingguo decisively gave the order to start the 'Mole Operation', and the various hummingbirds began to act. The Hummingbird A-20 is close to the bottom of the aircraft carrier, and when it is only ten centimeters away from the bottom of the ship, it begins to release a controllable bubble wrapped in liquid gel from the top of the hummingbird, which will continue to expand as the bubble is inflated at high pressure and will finally attach to the bottom of the ship, forming a cavity between the bottom of the ship and the high-energy laser of the hummingbird, and then the laser will perform efficient metal cutting operations.

According to Gong Qingguo's plan, each hummingbird will carry out six cutting operations to form a hole 600 millimeters deep and 1,000 millimeters in diameter, so that even if the bottom of the aircraft carrier is thick, it cannot be half a meter thick, and no matter how many isolation cabins there are, it will not be able to isolate all the 120 large holes, even if it is a double-layer bottom, as long as the hummingbird does not see the light, it will always be cut, and all the holes will be opened on the side of the bottom of the ship, even if the design of the aircraft carrier is as strong as a beehive, it will capsize due to loss of balance, Even if the aircraft carrier urgently fills the other side with water to adjust the hull balance, it will sink because it exceeds the limit. In order to prevent the huge suction caused by the sudden inflow of seawater, each hummingbird is supported around the bottom of the ship by three mechanical arms converted from the original missile compartment to ensure that the hummingbird can safely move to the next operating position. The overall action time of the plan was one hour, and Gong Qingguo asked 'Superstring' to calculate that if everything went well, all the punching operations would be completed in forty minutes.

In order to be safe, Gong Qingguo also formulated two sets of backup plans, in the above situation, if the aircraft carrier is still not sunk, the Hummingbird attack group will continue to punch holes in the side hull below the waterline, and the final plan is for the Hummingbird A-30 to launch all the carried proton torpedoes to attack the bottom of the aircraft carrier, Gong Qingguo is determined to complete the mole plan.

Time passed minute by minute, as the hummingbird kept moving its position, there were more and more big holes in the bottom of the aircraft carrier, and some big fish were even sucked into these holes, and Gong Qingguo breathed a sigh of relief when the plan was more than half a year old, because according to the calculation, the current holes are already the number of holes that can sink the aircraft carrier.

The distress message sent by the aircraft carrier of the advance fleet shocked General McVeigh, who was about to go to bed, and the two aircraft carriers at the front reported at the same time that there were many huge holes in the bottom of the ship for unknown reasons, and the sea water was pouring in in large quantities, and the rescue measures must be too late, and all the isolation hatches had been urgently closed and the emergency drainage system had been activated, but the speed of the sea water influx was extremely fast, and the hull of the ship had begun to tilt, asking for assistance and instructions. McVeigh stared at the display screen in the general's cabin in a daze, on the screen, the advance fleet had stopped advancing, this was the first time since departure that it had stopped advancing towards its destination, and before he knew it, the model of the sail battleship that McVeigh had just put on the bedside table had been knocked to the ground, and many delicate parts of the delicate sails and hull had been shattered on the thick carpet.
