The plank road was built openly to secretly travel to Chencang. When the Republican Army decided to enter the Northeast, it also used the two-line strategy. On August 11, 1704, Hai Song's army had completely occupied Chenyang, the most important city of the Wu family. During the first fourteen days, Hai Song did not encounter the imagined enemy. Xiao Xuan, as the commander of the Northeast Hai Land, and Hai Song's entire army seemed to feel victory and go back again.

But at this time, the Republican army in the Beiping region began to move towards Shanhaiguan, which immediately made Hai Song nervous. Faced with the Republican army's posture of kicking the door, even though Hai Song understood that he was very firm in guarding this strategic channel, he was ready and mobilized a large number of troops. A fleet of eight warships began to berth in the Bohai Bay.

Although it is defined as a secondary battlefield, today's battle will surely be recorded in history. On a runway composed of small stones in the western part of Qinhuangdao, a large group of crew members were wearing protective suits to conduct final inspections on the fighter planes.

On the land twenty kilometers away, the soldiers of the Republican Army moved on the ground. It seemed that they were moved by the artillery of the Song Hai Fleet in Hai for two weeks. The Republican Army's troops were a small team of reconnaissance approaching the defensive land acquisition laid by the Song army in Shanhaiguan.

Here we can show the heroic spirit of an industrial power. The barbed wire mesh is continuous with barbed wire mesh and cement-cast fortress. A stronghold is surrounded by a stronghold. This stronghold cannot be broken through if it is a traditional attack.

In Beijing, Ren Di has left at this time and is not here. However, Ren Di’s retaliation plan is being implemented in an orderly manner.

The sea breeze is very cool and the sun hangs down from the sky, which makes people fascinated. The soldiers on Hai Song's warship are busy. Two of the eight warships are heavy patrols of 9,000 tons, three are destroyers of 5,000 tons, and the remaining three are destroyers of 3,000 tons. This is the era of ironclad ships. Only Hai Song in the world can make large quantities of ironclad ships, and even the lightest destroyers' firepower is not something that the fleet on the road can look up. As for the aircraft's ammunition load so far, the aircraft's ammunition capacity is still Hovering around 200 kilograms, cutting wooden structures cannot make the aircraft dive bombing under full load. It cannot pose a physical threat to the warships. As for fish #thunder, this thing is too technological. Fish #thunder technology. The technology exposed to Haisong is now the international technology of fish #thunder powered by compressed air. The range is between 150 meters and 600 meters, and the launch route is still affected by the water flow. To solve this problem, it actually requires adding a gyroscope.

However, the problem of fish # thunder range and safe throwing into the water and then starting is basically the Republic, two five-year plans. It is basically impossible to use small planes to sink warships these days.

But in theory, the ironclad ship can only be destroyed in the sea except for ironclad ships. Today, I encountered something disgusting. When the black plane arrived above the fleet, the crew of the Haisong fleet hurriedly started shooting in the machine gun array position, and were welcoming rockets with tail flames.

Warships are not afraid of low-energy explosions, because the explosion energy exists very shortly, and the stress of steel can catch the explosion's shock wave. Therefore, if the rocket is loaded with explosives, it will not pose an ideal threat to the warship structure. However, this time it is not loaded with explosives.

It is a mixture of mustard gas and Louis's gas (called Dew of Death in this plane). The rockets hit the superstructure of the warship and "Peng" sputtered out. The main gun turret of the warship in this era may have been closed, but rapid-fire firepower, especially air firepower, is not closed. As one rocket after another hits the warship, it is like spraying insecticide on it. From the plane, people as big as insects on the warship suddenly become quiet. Don't mention the cannons that fired in the air.

Chemical raid warships are something that industrial countries don’t bother to do in the 21st century, but almost all naval powers have practiced the countermeasures of warships being raided by chemical weapons. Obviously, Hai Song’s fleet did not expect that such sudden situations would occur today. Poisons permeate the entire superstructure, and it was poisonous gas with very fast force. The entire deck was already terrible. Like hell, the people on the deck were frantically scratching their flesh and blood, and their whole body was covered in blood and eroded in large areas, their hair fell off, and then they were desperate to fall into the sea. As for the damage team, the team could not do this situation, because the warships were poisonous gas, not fire, and the gas mask could not cover it at all.

The Republican air force raid was divided into three waves. When the first wave solved the deck's defense force, the second wave began to lower the height and tried to fire poisonous gas rockets on the battleship building. As long as a poisonous gas ejected into the house, the task will be completed.

When the huge weapons of steel warfare are no longer activated, then this is not a contest between the steel warships and the tiny wooden planes, but the Republican air force, and then uses chemicals to clean up protein organisms in steel buildings.

When the fighter jets pulled across the sea and began to launch precisely the possible entrances of the battleship, the windows and hatched doors of the rocket iron railings allowed a trace of poison gas to leak in. The members of the battleship retreated frantically to the watertight room on the lower floor, and firmly closed the door with only one circular glass window. It is expected that after this battle, these warships will be disinfected alone. The trouble is no less than repairs.

What's more, the last wave of pilots hung on the fire bomb. By the way, a fire was set on the warship. No one dared to come out to rescue him. The fleet that was ordered to stop him was received so grandly as soon as it arrived at the sea near Shanhaiguan. Two hundred aircraft were treated with four special rockets, and a raging flame was lit above the eight warships.

Huge columns of smoke emerged on the sea, just like a fleet was about to sink, but in fact they were just smoke.

This time, when the Republican Army arrived outside Shanhaiguan, it was actually not intended to seize this position. It was precisely what Hai Song's Xiao Xuan thought about here for a moment, and wanted Ren Di to fail here once. After all, the reputation of victory is also very important in Hai Song.

When a large number of troops gathered in Shanhaiguan, the Republican army also gave the best chance to carry out a poisonous gas war.

The wind here in Qinhuangdao is popular in the southeast all year round, and it is sea and land terrain, so it blows to land during the day and to the ocean at night. It is used to fight poison gas wars on land, especially to use industrialization to release a large amount of suffocating poison gas. If the wind direction and terrain are well coordinated, chemical poison gas will accumulate in a zone and remain concentrated and spread, and the lethality of chemical weapons is no less than that of nuclear bombs. The key to poison gas war is to master the microclimate characteristics of the battlefield. This is also Ren Di’s professionalism before crossing, but he never thought of using it like this in the past.

However, the wind direction in this Shanhaiguan area is stable during the day. And when the sea breeze blows gas two or three times heavier than the air to the land, it will be blocked by the Yanshan Mountains and move northward along the mountains, forming a narrow tube effect of the wind blowing of the mountains and the sea surface. Now it is time to inject poison gas into this narrow terrain.

Since we are going to fight a poison gas war, we will fight a poison gas war that is recorded in textbooks and recorded in history. We must do whatever we do.

When the contaminated poison gas bombs of the warship Republic Army on the sea were driven away, Xiao Xuan learned through telegram that the firepower support could not be provided on the sea, and he suddenly thought of the lack of such a large area of ​​firepower support on the combat front.

The cup full of red wine on the floor was mercilessly broken. Xiao Xuan, who knew that his fleet was attacked by a large-scale chemical weapon airdrop, showed anger and flushed on his face. He was so angry that he was angry. A week ago, his boss, Beiliang, of the Northeast Asia Command, criticized him for wantonly starting a chemical war. As a result, he was suppressed by his family. For so many days, as the Liaoning area was controlled by himself. The poison gas storm also retreated with the Republican Army without any sign of attack.

Just after Hai Song's observers believed that the Republican army seemed to weigh the pros and cons and suffered this secret loss, Ning Shixi people did not expect that such a fierce revenge would be waiting for. Thirty percent of the carrier-based personnel died, and more than 90% of the surviving personnel received poison gas injuries of different severity. When the fleet heard the news, Xiao Xuan's whole body was like thunder. This was not Ning Shixi people, it was simply sharpening his knife these days.

However, the situation forced Xiao Xuan to return to the present. Considering that the Republican Army suddenly drove away the fleet on the sea surface and gathered on the Qinhuangdao generation on a large scale. It was very likely to be a sign of a large-scale raid on the Haisong defense line, Xiao Xuan thought about it and immediately asked the 15th Army to take a train to reinforce. However, this order was wrong.

The Republican army's items loaded with skulls quickly arrived at the front line under the escort of soldiers, wearing pig's nose gas masks one by one. When the train arrived at its destination, soldiers wearing plastic gloves quickly put the cylinders down from the carriage. Since they were going to fight a big poison gas battle, the amount of shells dropped far less than the amount of poison gas directly using the cylinders to discharge poison gas.

Under the cover of large smog of straw burning, the barrels were transported to a fixed line of several kilometers. The first generation of poison gas used in the battlefield since the chlorine gas industry has been particularly thick. As the unified time arrives, a row of yellow-green fog walls appear on the ground, slowly drifting along the north ground along the sea breeze. Under the blue and blue smoke screen, this strange yellow-green lies on the ground very lowly and moves with the wind.

Later, Hai Song estimated that at least 3,000 tons of chlorine gas were released in this battle. However, in all the databases of the Republican Army during the war, it was recorded that only 200 tons of chlorine gas were released. On the land, chlorine gas was arranged in a row and advancing with the wind was despairing. The green was filled with gas that was blown by the entire respiratory tract by a knife. In the first battle of the Southern Hai Song troops, who had just arrived in this land, saw unprecedented cruelty. During the large area of ​​green smoke, a large number of soldiers breathed and were stirred by the knife before their death. As the fog advanced continuously, it seemed like ghost fog, and the pursuit could not be shaken away. The poison gas advanced at least forty kilometers. Many soldiers were tired from running and then submerged in the poison gas green. The green smoke passed through the sky and there was no insect chirping on the ground.

The front of the 16th Army was exposed to the strongest fog of death, with the most severe damage. When the wind direction changed after entering the night, the wind direction of the sea blew land during the day and turned to the ocean at night. The poisonous smoke along the coast finally retreated towards the sea, leaving behind a corpse-ridden land everywhere.

Hai Song realized the cruelty of the poisonous gas war for the first time.
