After tossing all night, Lu Wei and the big man just couldn't learn, so Lu Wei had to go to the equipment research room and the designers for a total of half a day, and designed a propeller that could be tied to the lower leg, with a cover around the leg in the middle, and eight small propellers around it, one tied to each leg, and the switch and speed could be controlled by hand.

After a day of rushing work to start the test of the new equipment, after the big man was tied, he went down to the water to turn on the switch, there were eight small white water columns behind his feet, the big man gradually began to accelerate, and when he was about to reach the pool, the big man's switch was not turned off in time, and he would not turn, and he saw a bubble in his mouth as if shouting: "Hey... Ay... Then he hit his head against the wall by the pool, and the group of people above was about to die laughing.

The big man experienced several more headbumps, and was able to swim crookedly under the water, and the trajectory also changed from irregular to smooth and free, and Lu Wei and several of them also began to train and quickly mastered the essentials.

After the trial, after summarizing and improving, equipped with a high-energy battery, which can continue to supply power for a month, and a special portable disposable inflatable bag, which will instantly fill the gas to make them surface when the valve is opened at a critical moment, each person is equipped with 3, fixed on the upper part of the military backpack, and the bionic body does not need additional oxygen, so it saves the bulky oxygen cylinder.

On the last night, Laura and Mickey also tied up their propellers, and everyone practiced underwater equipment and tactics, but because the pool was a bit small, it did not achieve the expected effect.

During the time when Shi Hao and they went to Uto City, the researchers of the carrier pigeon and the equipment research laboratory designed and developed a quantum communication headset, the size of a grain of rice, which can be implanted in the ear canal of the Lingshan-level bionic body, activated by the holographic watch and telephone all-in-one machine when used, and turned off directly when not in use, the distance of single or multi-person direct connection is about ten kilometers, ignoring obstacles, and it can be used without hindrance underwater.

In the past few days, they have also conducted an underwater call test on this communication headset, and the reception effect is very good, but when people are underwater, a mouth of water will pour in, there is no way to communicate, the carrier pigeon went back to find someone to modify the program, and the position of everyone is presented on the watch screen through the red dot, and the position of other team members can be judged by the red dot underwater.

Lu Wei observed and recorded on it, he will write an underwater training outline after he goes back, and in the past two days, the Panlong base has begun to plan to build a swimming pool, and the length and depth have been increased by more than three times.

On the morning of the sixth day, Shi Hao took Wang Ping's eight people and their respective combat pets to fly to Zhefu Province in a saucer-shaped aircraft, and after the sea level rose, most of the coastal areas were flooded, and the original Fu Province and Zhejiang Province were merged into Zhefu Province, and Huajin City was expanded into the provincial capital.

Joaquin City, Operations Command Room of the General Headquarters of the Southern Theater of Operations.

Zong Zeyu pointed to a large electronic map on the wall and explained: "These places marked with red dots have been attacked, there is no pattern, each attack is only a few minutes, and they retreat after the attack. ”

"Our people and boats are scattered in these areas and patrol non-stop, using the method of guarding the rabbit to prevent it, but the effect is very bad, and a lot of manpower is wasted."

"After all this period of tireless efforts, we found and tracked their submarine, but when we got to this place, we were nowhere to be found." Zong Zeyu pointed to a place in the sea near this country and said.

But judging by the maps, pictures and videos, there is only the vast ocean, and there are no islands or land in sight.

After many earthquakes, most of the land has slipped into the large trench next to it, and the area of the country that is now exposed to the sea is not even one-tenth of its original size.

Zong Zeyu saw Shi Hao's puzzled expressions, and said with a smile: "There was originally a big island in this location, but after the sea level rose, it was all submerged. ”

"We sent a fish-shaped reconnaissance robot to approach the reconnaissance, a few hundred meters away with sonar waves can scan the outline of the island, the entire island is surrounded by infrared, laser, magnetic and other monitors, the reconnaissance robot can not move forward, we have arranged some long-distance monitoring on the periphery, you can see that there are submarines in and out.

"Given the international implications, and we have no direct evidence, we can't use heavy weapons, we can only rely on you."

Shi Hao and the others raised some detailed questions for discussion, and then asked Zong Zeyu to arrange a speedboat, they were ready to go to sea for training, and they needed to conduct effective combat training as soon as possible.

After the speedboat took them ten kilometers into the sea, Shi Hao asked everyone to equip the propellers, activate the communication headset, and then start to launch.

After entering the water, the body began to sink, they just started to put their feet down, by controlling the speed of the propeller to stop the body from sinking, Mickey tried to turn the speed to the maximum, his body was pushed upward, and jumped high out of the water like a fish.

The bottom of the sea is not as flat as a swimming pool, there are aquatic plants, stones, and schools of fish, and they have to turn by swinging their hands and feet from time to time, floating and sinking, and after several hours of training, they become more and more proficient, and they swim farther and farther, and the distance between the nine people is getting bigger and bigger.

The big man's swimming in the original army was his shortcoming, and as he became more and more proficient in controlling the propeller, he was like a fish in water, and the rise of play, before he knew it, the red dots on his watch disappeared.

Just when he was chasing a big fish, he suddenly felt a pain in his back, and without looking back, he directly turned the propeller to the maximum, rushed out, and then swung his right leg back to the right and rotated his body, and found that four black people were chasing him with long knives shining silver.

He thought that he should have been slashed just now, and the big man was wearing a protective suit specially made for the Panlong team, and the knife was not cut through.

The big man wanted to call for support in a hurry, his mouth was open, and he poured a mouthful of seawater, and immediately turned on the watch screen when he reacted, it was pitch black, and he couldn't find his teammates and couldn't figure out the enemy's reality, so he quickly turned around and accelerated to swim forward.

After running for a while, he found that if he accelerated to a certain speed, the other party would be slowly thrown away, and his heart was much more stable, so he deliberately slowed down and hung the four people behind.

Changed a few directions, swam a few kilometers in each direction, but the watch screen was still dark, he also dizzy, and finally opened the compass that came with the watch, found a general direction and swam all the way, he didn't locate the starting place when he came out, so it was useless to rely on the compass alone.

Shi Hao and Wang Ping all returned to the speedboat, but they couldn't wait for the big man to come up, thinking that something should be wrong, and they couldn't find it on the watch screen, so they asked the carrier pigeon to turn on the quantum communication switch, and then they saw that the big man was thirty kilometers away, at an angle of 15 degrees to them, moving quickly towards them in a straight line.

When the switch was turned on, the big man's watch also sounded, and at the same time he saw the other eight red dots, and began to control the speed and hung the four people behind him towards Shi Hao and them.

The big man brought the watch to his mouth at this time, opened his mouth and said loudly: "Enemy attack... Four... After saying these four words, he drank more than four sips of water.

What Shi Hao and they heard was: "Enemy, goo dong, attack, goo dong... Four, goo-dong, one, goo-dong... Although I didn't know, I also understood, Shi Hao began to deploy the battle, the carrier pigeon and Wufeng were on standby on the speedboat, Shi Hao and Lao Hei met from the front, Wang Ping and Mickey were outflanked from the left, and Laura and Hei Yu were outflanked from the right.

Three groups adjust the speed and angle according to the position of the big man and spread the net.

The big man looked at the distribution of the six red dots, understood Shi Hao's intentions, and cut in from the middle of the opening, and the four people were unaware.

These four people are liquid metal robots released by this day, the target of this attack is a town more than ten kilometers away from here, they are ejected from the submarine torpedo tube, before the ejection, the attack program is activated, and the target will be attacked indiscriminately, so after encountering the big man, it will be in hot pursuit.

When the big man swam in, the three groups of people began to quickly move closer to the big man, the big man came to a sudden brake, stopped and turned around with a dagger in his hand and rushed towards one of them, the man held a knife to make a straight stab, the big man turned off the propeller switch, his body sank quickly, and then opened again, and rushed over diagonally, the dagger was like piercing into dense rubber, and hit the man in the abdomen.

Shi Hao drove the propeller speed to the maximum, and when he swept over a person's head, he grabbed the long knife with his bare hands, the person let go of the handle under Shi Hao's strong pull, and his body was rolled backwards, Shi Hao did not slow down, and quickly rushed to the person who was rolling towards him, the hand that did not hold the knife grabbed the person's ankle this time, the man tried his best to break free, the liquid metal robot was not very heavy, so it was very flexible in the water, Shi Hao's body rotated and dragged the person upwards to the surface, and came to the side of the speedboatHe threw it up and shouted at the carrier pigeon and Wufeng, "Tie it up strongly." ”

After saying that, Shi Hao sank quickly again, and at this time, the big man, Mickey, and Laura all stabbed a certain part of the remaining three people, but it was useless.

Wang Ping, Lao Hei and Hei Yu also made up for it immediately afterwards, and they were still the same, useless.

Seeing this, a few of them worked in pairs, grabbed knives like Shi Hao, pulled their arms or legs, and dragged these three people out of the water.

Everyone got into the patrol boat and tied the four men with a cable knot.

Shi Hao came to a person, lifted his clothes, and saw that the exposed skin was silvery-white, confirming that it was a liquid metal robot, and then used a dagger to pull a slit in the chest position, broke it hard, and finally found the electronic control core in the abdomen, but he did not take out the core rashly, worried that the submarine would find an abnormality after the robot was destroyed and become vigilant.

When Shi Hao pulled out the dagger, the slit that had been opened completely disappeared after ten minutes, and the robot was back to its original state.
