The locomotive spewed steam and plunged headlong into a deep pit full of water, the water poured into the boiler, and a cloud of steam was raised, and the locomotive hit the pit wall, and the carriages behind did not stop, but were still rushing forward, and the first carriage fell into the pit, and the carriages behind rushed out of the tracks, and suddenly lost their balance and fell to one side. The carriage slid on the ground and knocked over a large tree before stopping, and the violent impact detonated the explosives on the car, and the violent explosion tore ten carriages to pieces!

Russia has not built many railways in Northeast China, and ten anti-runway bombs have almost paralyzed the entire Russian railway network in Northeast China, and the Russian army has only two choices, one is to walk along the country road, and the other is to rush to repair the railway...... This set will take the Russian army fifteen days.

The Russian army in Changtu heard that the support was blocked, so they sent a note to Japan, postponed the march, and then made later historians laugh that something happened: the Russian army did not think that these deep pits were caused by Lin Yuan's bombing, they thought that this was a geological phenomenon, so they organized geologists to study, but they had no clue for half a month, until the chemical element analysis of the soil in the crater was carried out, and a large amount of iron was found in it, and Russia concluded that the crater may have been caused by a meteorite.

The Russian Allied forces that Dashan Yan was looking forward to were blocked hundreds of kilometers away, and the reinforcements were still trudging the post road, they found that there were several deep pits on the post road, which meant that the process of moving ammunition and carrying the carriage had to be repeated several times, Lin Yuan sent the marines to form a special operations team, specifically harassing the Japanese army along the post road and destroying the post road.

Lin Yuan very much hoped to be able to see Dashanyan again, tell Dashanyan about his plan, and then tell him that the final victory was still his own, but he did not do so, he ordered the Dingwu army stationed in the eastern city to give up the east gate, so that the Japanese army could enter and exit freely at the east gate.

If a city is completely surrounded, then the enemy will fight to the death with all his strength knowing that there is no way to escape, and when a gap is left, the will of the defenders will be dispersed. However, Liu Dart, the co-commander of the Dingwu Army, disagreed, and he persuaded: "Lin Shuai, the little devil will definitely resist to the end!" Moreover, the inner city wall of Mukden is very thick, and the cannonball hits it is a small pit, and after the lessons of the outer city, it must be difficult for us to seize the city gate, so it is better for us to completely surround the inner city. ”

Lin Yuan said with a smile: "The Japanese army has hoarded enough food in the inner city, and there is enough groundwater in it, and we can't cut off their water source, so besieging the city is definitely not a good way?" ”

Wu Yuankai then asked: "Then Lin Shuai has a good strategy to break the enemy?" ”

Lin Yuan said: "Of course, order the troops to wait outside the west of the city, and when the time comes, I will find a way to blow up the city wall, and then you will rush in with all your might!" ”

The Japanese defensive position outside the city was 800 meters from the city wall, and on the night of April 6, the Qing army launched an attack on the western outer defensive line in five directions, and soon took the western defensive position.

Then the Qing army stood by in place, waiting for Lin Yuan to blow up the city wall, many veterans had no bottom in their hearts, because they knew that they needed at least explosives to blow up the city wall, but Lin Yuan did not have the slightest intention of mobilizing explosives.

And what makes everyone curious is: in the trenches, there is a bunker, which was personally ordered by Lin Shuai, and no one is allowed to approach!

Inside the bunker, Deng Hong and several Marines were operating a laser designator, a laser beam hit the city wall, and then reflected into space, and a few minutes later, a carrier-based aircraft flew over the target with laser-guided bombs.

The J-25 dropped a 200-kilogram laser-guided bomb, and when the bomb left the carrier aircraft, the laser gyroscope inside the missile body began to work, guiding the bomb to glide in a predetermined direction.

At the same time as gliding, the laser receiver located in the head of the bomb began to search for the laser sent by the indicator, the bomb quickly locked onto the target, the motor in the missile body began to adjust the control rudder surface on the missile according to the orientation of the target, and under the impetus of the air, the gliding direction of the bomb pointed to the city wall. Deng Hong and they aimed at the root of the city wall, when the bomb exploded in this position, they could destroy the city wall as much as possible, the bomb carried the sound of the wind, like a lightning bolt hit the root of the city wall, and after a muffled sound, a thick smoke rose.

When the smoke subsided, Deng Hong and the others were surprised to find that the city wall did not collapse, but opened a big gap in the position of the wall root, so Deng Hong and they decided to put another bomb in the position of the gap.

Laser guidance has one of the biggest drawbacks, that is, the laser is unusable in rainy and snowy weather and in the presence of smoke, so if you want to use the laser to indicate the location again, you must wait until the smoke clears, they did not wait too long, when the smoke dissipated, a bomb from the position of the gap into the city wall, a huge explosion, the city wall opened a hole more than ten meters wide!

To everyone's surprise, there were loud cheers in the city!

It turned out that after the Japanese army lost its outer defensive positions, in order to prevent the Qing army from burying explosives under the base of the wall and blowing up the city wall, they gathered the people of the whole city and took sandbags.

And the Japanese army also has a sinister intention, that is, after the Qing army blows up the city wall, it will definitely rush into the city through the gap, so that the common people who are blocked in the gap will become the first barrier, and when the time comes, the Japanese army in the city can shoot out, and the Qing army outside the city will not dare to shoot!

The common people were bullied by the Japanese army, and now they saw that the city wall was blown up, and the day of liberation was coming, so they cheered!

The Qing soldiers didn't care where the cheers came from, they picked up their guns and rushed up, and the masonry on the city wall was blown apart, so they entered the city without much effort, and to their surprise: there was only a group of ordinary people carrying sandbags in the city, and they did not even see the shadow of the Japanese army.

It turned out that according to past experience, if the besieging party wants to blow up the city wall, it must first send people close to the city wall, and at this time, it is difficult not to be discovered by the defenders, and the defenders will immediately counterattack, so in the attack and defense of the city wall, blowing up the city wall is an extremely dangerous thing, but this time Lin Yuan designed the wall bombing operation, but it came from the sky, and the Japanese army was defenseless, so there were not many defenders in the gap at all.

The reaction speed of the Japanese army was still very fast, and their rapid reaction cavalry immediately rushed towards the gap, but halfway through the run, they were surprised to find that there were suddenly a lot of sandbag piles on the road, and those sandbag piles were so high and chaotic that the war horses really couldn't pass, and the Japanese army began to figure it out.
