Lu Qingshan ran out of the back door of the house, just in time for the flares fired by the Japanese army to fall from the sky, he suddenly found himself in a huge light, and the huge figure under his feet stretched dozens of meters away.

There was no time to wait for darkness to fall, he had to cross the open area again, return to the place where he had just landed, the oxygen cylinders hidden on the bank of the river had to be taken away, he could not just find a safe place to enter the water, which of course meant a huge risk.

Sure enough, the Japanese saw a dark shadow running away. The quick hands began to shoot at him. The bullets grazed his ears, getting closer and closer, and he quickly crossed the highway and ran past a series of burnt cars that left only black wreckage. The flares landed in time, allowing him to take refuge in the darkness and run for a distance again, and the Japanese gunfire stopped. He re-entered Qin Xiaosu's cover, and he didn't know whether to be happy or worried.

The second batch of flares of the Japanese army was launched into the air, and this time there were many of them, and they were very chaotic, and the time of their fall was also in different order. Lu Qingshan hid in Artemisia Grass, but the Japanese machine guns followed closely and fired at the violently shaking Artemisia Grass. An armored car crossed the road and immediately joined the fire.

Qin Xiaosu turned his gun and fired at the armored car. This time it was not so easy, he was facing a moving vehicle, and the advance calculation was not available for intelligent fire control. He shot continuously, correcting quickly based on the point of impact (he could see the trajectory in his night vision goggles), and felt like his shoulders were almost falling apart. Shot out *, the armored car was finally stopped. The anti-materiel gun left a 12.7 mm bullet hole in the side of the armored vehicle, as if a heavy machine gun had strafed.

Lu Qingshan walked through the artemisia meadow, listening to the dog barking behind him, the Japanese military dog had good night vision, followed all the way, listened to the movement and ran very fast, obviously no soldiers followed. Of course, he was not afraid of wolf dogs, but this barking of dogs would definitely attract the attention of the Japanese soldiers. He paused to catch his breath and waited for the wolfdog.

A military dog pounced on him through the grass and raised his hand to kill the wolfdog with a single shot. Then he quickly got up and ran again, the last obstacle in front was the enemy's trench along the river, and when he crossed just now, it was naturally Qin Xiaosu who broke the generator. Drone observation, there are still a lot of soldiers guarding here, but the * that was deployed here before can be useful.

Lu Qingshan ignored the approaching of the pursuers behind him, waited for the last flare to fall, pushed on the night vision goggles, and rushed out of the grass and ran towards the trench. He could see the Japanese soldiers in the trenches and on the watchtowers, they were already dizzy, shooting at the motorboats on the river for a while, and the explosions were behind him again, and the battlefield was even darker and brighter for a while, and the orders from their superiors never came, and they couldn't figure out what was going on. It's all up to personal judgment.

A signal flare behind Lu Qingshan screamed and flew into the sky, before it flew above his head and shone on the earth, he rushed to the trench with all his strength, and through the night vision device, he could see the dazed Japanese army looking at him, of course the Japanese army saw a black shadow rushing over, but he really couldn't figure out whether it was his own person. Lu picked up a kick and lifted it in the face of the Japanese, crossed the trench with a scream, jumped over a barbed wire fence in depth, and quickly rolled to a low-lying place where he knew that the * behind him was about to explode. The Japanese soldiers who had chased Artemisia had arrived, and under the light of the flares, they saw the direction in which Lu's back had disappeared over the barbed wire, and shouted and chased after him. The Japanese troops in the trenches continued to be in a daze.

In an instant, the drone operator gave the detonation command to all*, and two pillboxes at each end of the trench and two towers with machine guns and searchlights exploded at the same time. The Japanese troops gathered around were caught in a sea of fire. The fallen tower smashed right on the trench, smashing the two machine guns deployed there.

Lu Qingshan ran to the reeds by the river, and quickly found an oxygen cylinder and carried it on his back. Qin Xiaosu's reminder came from the earphones, and there was an enemy motorboat approaching on the lake.

Behind him, enemy flares rose one after another, and the river was in front of him, Lu Qingshan decided not to delay any longer, biting the breathing apparatus and rushing towards the river. 40 meters away on the river, enemy motorboats rushed towards them. Knowing that there was no way out, he had to gamble his luck and jumped into the lake in the face of enemy gun-machine gun fire, where the enemy's light machine gun continued to strafe at the place where he had disappeared. Soon a second motorboat arrived.

Qin Xiaosu hurriedly aimed, his fire control that automatically calculated the trajectory was completely ineffective against such a fast-moving target. Just as he was catching the blind, someone arrived and pushed him aside. The person who came was Lin Xiuxuan. He quickly snatched the anti-materiel gun, and as he took aim, he turned off the nasty light point indicator.

"Distance, wind speed!" Lin shouted. He's back to the old days, and he needs experience to mix cold numbers.

“1550，4.5。”

Lin Xiuxuan quickly judged the average displacement of the enemy's motorboat in the direction of movement, and the enemy was not moving vertically in his firing line, so it was very difficult to calculate the amount of advance and comprehensively evaluate, which was not possible with ordinary simple disturbance fire control, only complex tank stable image fire control could do it, but sometimes, the human brain could make accurate estimates with experience, which was really amazing.

Lin pulled the trigger, and a bullet flew 1.5 kilometers away, in fact, there was a lake where there was nothing, and any advance shooting, in essence, required a precise calculation of the timing of the bullet and the target colliding.

Qin Xiaosu observed with a thermal imaging telescope, and he saw the machine gunner lying on the bow of the ship flying into the air, and then the motorboat capsized to one side, and the power of this gun was really not small.

Lin then aimed at the second motorboat, which was much easier, and the enemy was heading in the direction of the island in a panic, almost on the firing line, so that there was no need to think about the amount of advance. But Lin lowered the muzzle of the gun, and he wanted the bullet to pass below the waterline.

The bullet pierced through the slim hull and at the same time broke the leg of a Japanese soldier. Qin Xiaosu watched as the motorboat sank into the lake in 10 seconds, and a Japanese soldier was lucky enough to float up and hug a piece of the boat, but Lin didn't waste a bullet to kill him.

"Team leader, what's next?"

"Next, of course, we wait, I hope you have fired so many tracer bullets and not let this place be exposed, otherwise our enemy will pounce, and we will not be able to respond to Lu Qingshan." He already knew from the drone that there was a possibility of exposure here.

They hid on the island, watching the chaos in the enemy camp, which did not seem to be paying attention. The intelligence of the drones is consistent with their observations, the enemy does not have spare ships to search the water, and at the same time, they should not have the courage to attack, and it can be seen that they are constantly increasing their forces and preparing for the second round of attacks. Soon the third and fourth armored vehicles arrived and deployed towards the surface. It seems that they panicked and feared that a landing fleet would appear.

Lin Xiuxuan anxiously waited for Lu Qingshan to appear, he couldn't carry out communication at the bottom of the river, as long as he surfaced, it would be no problem, if he was okay, he should immediately surface to resume communication, but after waiting for a long time, he didn't wait for Lu Qingshan's signal. Lin thought, maybe he didn't want to take the risk, and hid at the bottom of the river. He comforted himself: Lu Qingshan is his most powerful subordinate, and his abilities in all aspects are very strong, and he will definitely be fine.

Thirty minutes have passed, the lake is unusually calm, and Lu has not yet appeared. The Japanese camp on the other side was much calmer, and the drones saw that they were constantly coming out of the dead bodies everywhere, and this attack was successful in all respects, except for Lu Qingshan, who had not yet appeared.

The boatswain reminded them that it would soon be dawn and that they would have to wait another 50 minutes at most and must leave. Lin was anxious, nodded haphazardly and agreed.

An hour passed, and Lu still didn't show up. Counting his oxygen, he has long since run out, so he should be on the surface anyway, as soon as he is on the surface, the drone will be able to track the location, whether he uses communication or not, unless the communication device is broken. Now it seems that only one worst-case scenario is left - he did not float.

The whole of 419 was in an unprecedented state of fear that they might be losing a teammate, something that had never happened in 15 months now. Lin asked the boatswain to immediately conduct a survey of the velocity of the water and concluded that if Lu Qingshan was wounded, he would drift to the depths of Hubo.

There was a dead silence in the command room of 419, everyone waited silently for a long time, and finally Cheng Dayang broke and sank, it was time for someone to break this matter. He grabbed the intercom.

"Team Leader Lin, it's dawn soon, and the enemy is bound to conduct a close search. I ask you to retreat immediately, and our drones will continue to monitor this place. Once Xiao Lu has information, we will rescue him. ”

"Captain Cheng, I want to stay, the reeds here are enough to cover me from the enemy's search during the day."

"Lao Lin," Cheng Dayang said leisurely, this was the first time he had used Lao Lin's title, "give up, we observed that the enemy was mobilizing troops from the city...... In a few hours, at least 2,000 people and dozens of sampans will search the place. Don't be pretentious. ”

Lin pondered for a long time, and he realized that Cheng Dayang's reminder was reasonable, Lu Qingshan was probably sacrificed, but he was unwilling to face it.

"Okay, let's withdraw."

He finally made up his mind, took his equipment and got on the motorboat, and soon there would be a large number of enemies here, and he couldn't stay nearby, so he could only go back to the submarine first, as for Lu Qingshan, if he died, it meant that he and his equipment would sink to the bottom of the lake forever, and the enemy would not be able to find out. As for the possibility that he did not sacrifice, Lin Xiuxuan and Cheng Dayang couldn't think of it for the time being.

The drone observed that the small flotilla a few kilometers away, also delayed for a long time and did not leave, and it is not known why. Whoever supposedly had already received it. The guerrillas stayed there, as if to keep an eye out for the unusual situation that had occurred after their attack, and after they left, the Japanese fought on their own for a while, and a large number of cars were blown up, and even lost equipment such as armored vehicles and motorboats, and one of the other side's small boats even drove out of the reeds to observe for a while.

As Lin Xiuxuan's group began to withdraw, the guerrilla flotilla also began to retreat, heading west, where numerous rivers lead to Baiyangdian Lake to the west, the largest freshwater Hubo in Hebei Province and part of the anti-Japanese base area in central Hebei that the Japanese could not control.
