The night was deep, the north wind blew slightly, and the wilderness was gray and mottled. Except for the slight sound of wind and the sound of swaying plants, there was no other movement in the wilderness. Several Goguryeo soldiers curled up in the crypt, poked their heads slightly out of the ground from time to time, looking at the darkness outside.

More than a hundred steps south is the camp, and there are wilderness on three sides, without trees to block the wind, and the cold wind is blowing unscrupulously. Although the soldiers hid in the big pit they dug out, and a piece of cloth spread above their heads to block the wind and snow, the effect of keeping cold is better than nothing.

Although they were wearing cold clothes, several soldiers felt cold and leaned against each other to survive the long night together.

As secret sentries outside the camp, they were on guard in the cold and cold wilderness and had to perform their vigilance duties, so they could not sleep even if they were sleepy. Once they were discovered by the generals who were temporarily interested in checking the police, they would have to eat a whip.

In the middle of the night, the enemy camp in the south was yelling and making a big noise. Although there was no follow-up movement, no one could guarantee that the other party would not launch a sneak attack in the middle of the night.

Maybe it is not certain to come from south to north, or to go around in a big circle, and launch an attack from the back.

At night, people's sight range became smaller, and they only relied on the sentries on the arrow tower to keep watch. When they found that the enemy was touching, the time left for the camp to react was basically the same as none, so secret sentries were needed to set up outside the military camp to extend the alert range.

The secret sentries arranged around the camp are dozens of steps to hundreds of steps away from the camp. Once an enemy really attacks, the sentries' situation will be very dangerous, but no matter how dangerous it is, you have to warn them to gain valuable time for the camp to organize defense.

That's it, being sent out to the camp as a secret whistle and blowing cold wind is usually a job that is unlucky. If it weren't for the fear of being caught by someone, many soldiers would have really planned to go to bed.

If you fall asleep and feel someone touched it, you will die. If you are slashed when you are awake, you will try your best to warn you when you find something wrong. Then you will die. Anyway, it is better to be lazy?

However, being hung up and beaten by the general will make you beat your life worse than death. Although the generals are actually unlikely to come out to check in the middle of the night, no one dares to take risks, so they still dare not be lazy.

The north wind blew, making the whistles tremble. The night became thicker and darker. I don’t know when it would take until dawn. At this moment, there was a different movement in the wilderness, which shocked the whistles everywhere.

The movement came from the north, and the north wind brought a little smell, which was very familiar to the secret whistle: it was the smell of a horse.

There are herds of horses on the upper wind direction, not one or two, but one group, otherwise the taste will not be so obvious.

Soon, a sudden sound of gong sounded in the wilderness, and then gong sounded elsewhere.

The sound of gongs suddenly alarmed the camp in the south. The sentries on the arrow tower woke up from their sleepiness, then knocked on the gong and whipped the horn, and the camp gradually became boiling.

The Goguryeo soldiers who were waiting for battle in the middle of the night were originally waiting for the battle. Now some soldiers rushed out of the tent with weapons and arrived at the camp gate under the command of the generals to prepare to defend the enemy, while the other people remained in the tent, listening quietly to the movement outside.

In order to prevent the enemy from using tired soldiers, the troops from all the troops of the Goguryeo Army camp were divided up. Even if they had to fight, they would take turns to defend themselves, so as not to rest when there was any disturbance.

The movement in the north of the camp was no longer the enemy's bluff. The rapid sound of horse hooves were mixed with fighting and screams, indicating that an enemy had broken through the secret whistle and attacked the camp.

The Goguryeo soldiers gathered at the camp in the north, each preparing to give the attacking enemy a headache, but the sound of horse hooves stopped a hundred steps away.

There were many dark shadows in the wilderness, and it was obvious that many people were gathering, but the other party did not rush to attack. Perhaps it was because he saw his whereabouts were exposed too early, so he did not intend to attack hard; it might be because he reorganized his formation and then suddenly exerted force.

More and more Goguryeo soldiers in the camp were mobilized. In addition to the north, they were also ready to fight behind the camp gates in the southeast, south and west directions, preparing to welcome the Zhou army's attack.

However, the opponent did not attack.

The invading enemy still stopped at about a hundred steps north of the camp, and seemed to be just lined up and had no intention of attacking.

It is not a solution to keep going like this. Maybe the Zhou army is laying out long-distance attack weapons such as large crossbows and catapults. Once the other party has finished laying it out, Goguryeo will have to be beaten.

Not long after, the camp gate opened, the first group of soldiers rushed out of the camp and galloped towards the enemy in the north. The second group of soldiers then gathered in the camp and prepared to attack afterwards.

The soldiers who attacked first did not take torches to avoid illuminating themselves and becoming targets. They rushed towards the heavy black shadows ahead without fear, and the distance between the two sides became closer and closer.

Gradually, they saw the approximate outline of the enemy. It was a row of carriages, and from a distance they looked like a wall, a wall stretching for hundreds of steps.

Such a large-scale car formation made the Goguryeo soldiers a little surprised. Before they could adjust their formation, they could smell the smell of the north wind suddenly became pungent.

The wind was heard loudly at the gust of the carriages, and the carriages seemed to be spraying outwards. The fog became thicker and thicker. As the north wind spread south, the Goguryeo army crashed into the thick fog head-on.

After inhaling the pungent gas, I feel uncomfortable with my mouth and nose, and my chest feels stuffy, which makes people cough. At the same time, my eyes feel uncomfortable and I can't help crying.

This is true for people and horses. The Goguryeo army that crashed into the thick fog soon fell over and fell on the soldiers on the ground. After coughing violently, they felt stuffy in their chests and began to breathe.

Breathing becomes increasingly difficult. Many people keep rolling around while pinching their necks, twitching all over their bodies, feeling gradually suffocating, as if they fall into a river and drowning.

However, now he is clearly on land and has not fallen into the water, but the feeling of drowning and suffocation is becoming more and more real. Many Goguryeo soldiers have lost consciousness in the suffocation.

The sound of horse hooves was heard, and the second wave of Goguryeo cavalry roared. At the same time, some archers in the camp tried hard to shoot out fire arrows, trying to light up the battlefield ahead and "show the road" for these cavalry.

The cavalry attacking also crashed into the thick fog that was heading south with the wind. They also felt uncomfortable when they breathed, but they thought it was thick smoke produced by the enemy's burning spicy things, so they just rushed over.

They vaguely saw the chariot array in front of them, but a short distance of dozens of steps became an insurmountable obstacle. More and more cavalrymen fell to the ground, and only a few people endured their chest tightness and forced their horses to rush forward.

As the feeling of suffocation became stronger and stronger, these cavalrymen used the faint lighting of the fire arrow to see the scene in front of them clearly, making them feel terrifying.

After continuously spraying thick fog, more than ten steps away, many pig-headed men stood, with their empty eye sockets and mouths protruding like pig's mouths, which looked very cunning.

This is the demon army from hell, releasing poisonous gas from the human world.

As consciousness remained, such thoughts flashed by, and the last few Goguryeo cavalry fell to the ground, struggling and twitching, suffocating to death on the land.

People wearing gas masks watched all this happen quietly, watching the attacking Goguryeo army collapsed in the thick fog, and watched the increasingly thick fog drifting towards the camp in the downward direction with the north wind.

The wind was moderate, and the thick fog was quickly blown to the Goguryeo Camp by the north wind. The thick fog that was constantly released by the long chariot array soon enveloped the Goguryeo Camp.

In the thick fog, screams and coughs were endless. The whole camp was boiling, like a pot of boiled water, noisy, lively, but very strange.

The people who released the thick fog listened to the screams, as if they were enjoying a wonderful music, which was quite enjoyable.

The experimental unit, codenamed "Cobalt", is dedicated to experimenting with various strange weapons on the battlefield. He once participated in the Battle of Jiankang, but now he appears again and also uses strange weapons.

The experimental troops only served the emperor and were ordered to join the war this time, and the experimental weapons invested were gas.

This gas is usually stored in high-pressure gas cylinders. After the upwind direction is released, it can poison any human and animal within a certain range of the downwind direction. The symptoms of poisoning are similar to drowning. The anatomical results show that the deceased's lung edema should be suffocating.

The gas that can produce the effect of "drought drought" is actually a murderous poisonous gas. Because the gas is yellow-green, it is called "chlorine".

The technicians of the experimental unit had dealt with this poisonous gas. At this time, they looked at their "masterpiece" and the enemy camp shrouded in poisonous fog, and couldn't help but look forward to it.

Chlorine is very expensive and it is troublesome to produce. This time, it was put into actual combat. It only took one dose to almost all the reserves for several years. I don’t know how many years I can save for the next actual combat.

So they cherish this practical opportunity and collect experimental data as much as possible.

According to previous experimental data, if chlorine is released at such a close distance, there will definitely be no ten in the Goguryeo military camp, and the main camp with a downward direction of several miles away will inevitably be affected. How many living creatures will be there at that time?
