There is simply no chance to fight back! The Japanese soldiers who were blocked by Lu Yuan in the street invariably had such a thought in their hearts, and the corpse at the corner of the street was the best proof of this. The Japanese army had no way to fight back, or there was no way to form a counterattack that threatened Lu Yuan, but Lu Yuan didn't want to let go of these Japanese soldiers who didn't dare to show their heads so easily. After a short pause, Lu Yuan took out an American M2 heavy machine gun from the storage space and pointed the muzzle of the heavy machine gun at the street corner over there.

After a long time, no more gunshots were heard, and the Japanese soldiers who were cowering in the street began to move a little, and two Japanese soldiers, at the signal of a Japanese second lieutenant officer, rushed out of the street with rifles. The appearance of two Japanese soldiers, Lu Yuan on the roof of the building had already noticed, but he did not react immediately, he was waiting for more Japanese troops to appear. The two Japanese soldiers who were exploring the way passed through the street one after the other, Xu felt that the danger had been lifted, and after more than ten breaths, a large number of Japanese soldiers finally appeared in the street corner that Lu Yuan had been looking at.

Seeing a large number of targets appearing, Lu Yuan, who had never had any big Zuo, stretched out his hands, and the M2 heavy machine gun was a two-handed grip with a push-button trigger. Although the design of the M2 heavy machine gun is light, due to the large caliber of the ammunition, once the continuous firing starts, the muzzle shake is a bit large, so Lu Yuan uses three or four bursts of fire at the moment, and can always maintain a relatively good accuracy.

"Da Da" Lu Yuan first shot at the machine gunners in the Japanese army, and then began to pursue those officers, and if someone in the whole street moved a little bigger, or was shouting, Lu Yuan would unceremoniously greet him with a bullet. The large-caliber bullets used in the M2 heavy machine gun can even penetrate the bean chariots of the Japanese army, let alone these mortal Japanese soldiers.

Lu Yuan's side didn't even finish the first bullet chain, and there were no Japanese soldiers still standing in the middle of the street, except for those who were dead and wounded, the other Japanese soldiers had already shrunk back into the street over there. Seeing this, Lu Yuan just smiled, then withdrew the heavy machine gun, and then slipped along the rope hanging from the roof of the building. Attacking the enemy on advantageous terrain and inflicting a large number of casualties on the opponent has become a habitual tactic of Lu Yuan, but the Japanese army does not know this.

Lu Yuan had already left the roof of the building, but the Japanese troops in the street on the other side did not know that the attackers had left until the Japanese troops from the other direction rushed over to meet them. "Eight Geyalu, you must find him, find him." The Japanese army was furious, especially Sato Usuke Osa, who took over Sasaki's command, and he was even more furious, because he and Sasaki, who had died in battle, were not only fellow villagers, but the two of them were still world friends.

The entire Hongkou District has been completely blocked by the Japanese army, and even the Japanese expatriates who originally lived here and want to leave the Hongkou District have to be sent to a barracks for temporary residence after being inspected by the Japanese gendarmerie. Until the attackers were identified, they had to be closely monitored by the Japanese army. As the gunfire in Hongkou District intensified and explosions rang out from time to time, a large number of Hongkou residents had already flocked to the Japanese checkpoint, and they were in a hurry to get out of here.

A street away from a Japanese checkpoint, Lu Yuan, who had just come out of the tunnel, was now squatting on the roof platform of a building, and in front of him was a homemade crossbow catapult. Lu Yuan originally wanted to use oil drums as projectile weapons, and use the * he brought into Hongkou District to make flying thunders to teach the Japanese army in Shanghai a hard lesson. It's just that the oil drum is too big, and if the angle is not enough, Lei Fei can't reach the bombardment distance that Lu Yuan needs.

And Lu Yuan's self-made crossbow catapult, not only small size, but also not small, Lu Yuan personally did experiments, such a crossbow catapult, can weigh more than 3 kilograms of crossbow * projectile to a distance of 400 meters, and the accuracy is much higher than the flying thunder. Before the plan began, Lu Yuan had been busy processing parts in the hardware factory that Xu Huanshan had helped find, and he knew that there were two types of crossbow arrows*, one was conventional* and the other was*.

Lu Yuan's self-made crossbow arrow* is similar to the explosive crossbow arrow that Lu Yuan used before, but the size is much larger, and the arrow shaft is also iron, and the bullet head at the arrow position also increases the charge. With a "whoosh" sound, Lu Yuan's first crossbow arrow* flew out, and the red lines painted on the warhead indicated that it was a burning *. Lu Yuan, who came from later generations, knew that compared with how bullets and even shells could be attacked, there was almost no chance of a fish that could slip through the net.

* There are two killing modes, one is that the highly viscous burning oil adheres to the human body, which cannot be removed, unless it is immediately covered with blanket and sand to isolate the fire, but it is also ironclad and deeply burned, which is more in line with the principle that the wounded are more troublesome than the corpse. The other is the most deadly, because combustion requires oxygen, and the addition of chemical ingredients to support combustion* will instantly deplete the oxygen around the explosion point, and the target in this area will suffocate to death.

Lu Yuan's self-made* was relatively simple, and he only added sugar, rubber crumbs, and white phosphorus to the oil, but even so, after three consecutive crossbow arrows* exploded, there was already a wail around the explosion point. Lu Yuan eliminated three spells in a row*, and the checkpoints that were originally strictly controlled by the Japanese army were already submerged in the fire, and the Japanese expatriates who had not yet been affected by the fire could only shout helplessly and scatter and flee, or watch the Japanese soldiers who were screaming and convulsing in the fire from a distance.

Lu Yuan on the platform just looked at it coldly, the tragic situation of those Japanese soldiers on the checkpoint, in Lu Yuan's opinion, was just the retribution they deserved, if it weren't for the Japanese army burning, killing and looting on the land of China, Lu Yuan might not have used such means to deal with them. Outside Hongkou District, Xu Huanshan, who had been paying close attention to the situation, also saw the fire, this kind of maggot like a tarsal bone maggot was terrifying to watch, and he couldn't think of how Lu Yuan could only get along with this means.

Xu Huanshan was surprised by this, and a large number of Japanese soldiers who rushed in after hearing the news were also terrified, this kind of fire that could not be extinguished with water, and could even melt copper coat buttons, was really too strange and cruel. Three * shots, Lu Yuan on the platform immediately evacuated, before the brigade of Japanese troops arrived, Lu Yuan, who had changed his outfit, had already mixed into the flow of people and disappeared without a trace. The fire did not stop the Japanese expatriates in Hongkou District from staying out of danger, after all, there was not only one way in and out of Hongkou District, and Lu Yuan quickly approached in front of another Japanese checkpoint with the flow of people.

This time, Lu Yuan did not continue to use *, but directly set up the M2 heavy machine gun on the roof of the building close to the Japanese checkpoint. After more than a dozen breaths, the heavy machine gun in front of Lu Yuan began to roar, and with the rapid sound of gunfire, the bullet casings kept being thrown into the sky, and a lot of dust was immediately stirred up by the barrage around the Japanese level. The barrage of destructive power began to harvest lives, and Lu Yuan on the roof of the building could clearly see that the lives were so fragile in the face of the metal bullet stream, and a human body could be torn apart as easily as a piece of paper.

In just a few seconds, a tragic scene appeared in Lu Yuan's field of vision, some flesh was torn alive by bullets, and blood from internal organs was sprinkled everywhere. Even the three-wheeled motorcycles and military trucks parked by the Japanese army at the checkpoint caught fire and exploded under the strong blow of the airtight barrage, and the Japanese expatriates who were originally congested here had to scream again and turn around and flee, but fortunately, the barrage shot by Lu Yuan did not soar towards them.

Lu Yuan has no idea of shooting bullets at Japanese civilians at the moment, after all, he has almost enough killing points, but if the situation changes, Lu Yuan will not mind turning his gun to deal with the Japanese civilians who are relatively easy to deal with. Lu Yuan, who has a full-view map and storage space, is like a monkey who jumped into the belly of the princess of the iron fan, flickering and tossing in the Hongkou District with great energy, and in the hour after dawn, more than 300 Japanese soldiers were wounded and killed by him.

Lu Yuan, who had succeeded continuously, temporarily shrank in one of the tunnels, while recovering his strength, Lu Yuan took out the prepared water from the storage space, and then opened the light curtain to check the total number of kill points he had accumulated while filling his stomach. "Hehe, it seems to be pretty good, if it keeps going like this, maybe you only need to hold on for three days and you will be able to save enough points." Lu Yuan needs to accumulate enough 100,000 kill points to return to his family, the non-stop fighting in the past few years and two consecutive sabotage attacks on the Japanese mainland have brought more than 90,000 kill points to Lu Yuan, so far, Lu Yuan only needs to earn less than 1,000 kill points, and he is about to complete the ultimate task of 100,000 points.

Hongkou District is the main gathering place for Japanese in Shanghai, and there are hundreds of thousands of Japanese living here, while Lu Yuan only needs less than 1,000 killing points, which is a sure thing for Lu Yuan. Lu Yuan hid in the tunnel to recover his strength, but the Japanese troops who blocked the entire Hongkou District were headless like flies, searching for Lu Yuan's shadow everywhere. More than half an hour later, Lu Yuan drilled out of the tunnel, but was immediately discovered by a Japanese military monitoring point arranged at a high height.

"Boom" Lu Yuan's vigorous throwing of * landed and exploded, taking advantage of the panic of the Japanese army at the entrance of the street, Lu Yuan, who was intercepted by the Japanese army before and after, had to rush into a shop on the side of the street quickly. "Boom" Lu Yuan, who didn't plan to stay here at all, immediately blew up the back wall of the store with *, and then moved quickly along the alley behind the store towards the three-story building closest to him.
