Unlike in the past, when the Democratic Alliance forces had to fire a shell before opening fire, this time, 144 122-mm guns opened fire at the same time, and the overwhelming spots of light were scattered on the opposite side.

"Oh, damn it, how can the Chinese be so crazy?" Sherman shouted: "Hide, take cover, try to save yourself in the shelling, I don't believe he doesn't send infantry to attack." “

In two or three days, the Northern Army also dug criss-crossing trenches, the depth was at least one and a half meters or more, people hid in the trenches and did not show their heads, even the damage caused by grenades was quite limited, because although the howitzer has a large curvature, it is not straight up and down after all, hitting in the soft soil in front of the trench, it seems to be amazing, but the fragmentation damage can be offset most of it, which is the natural advantage of the defending side.

So Sherman wasn't too worried, as he estimated that the NLD would fire 20,000 shells, which would cause a few thousand casualties at most, and then it was time for his brave and fearless soldiers to crush the invading enemy, fantasizing about the wonderful scene of the Gatling gun tearing the enemy's body to pieces.

"Your Excellency, look at it, it doesn't seem quite right." A staff officer shouted.

Sherman also noticed the anomaly, the cannonball landed, and the explosion exploded, but the force seemed to be very small, only emitting a yellowish smoke.

"What the hell are the Chinese doing?" Sherman's face was bewildered.

But there was a riot among the soldiers on the front line.

"Oh, what the hell, my chest is so stuffy, I'm having trouble breathing, I'm running out of breath, God. Help me, I'm dying. ”

"I'm so disgusting. I want to vomit, vomit~~"

"I'm dizzy. Weakness, God, why are my muscles contracting? Stop, stop, my leg is cramping! ”

"I embraced all the symptoms you mentioned, oh no, I really can't!"

We all have the instinct to avoid danger, especially in the face of unknown dangers. Many soldiers crawled out of the trenches, spread their feet and ran back, but as they ran, they fell to the ground and shrunk into a ball, with convulsions and convulsions, foaming at the corners of their mouths, and inhaling in large gulps, with expressions of despair and pain.

Sherman and the fighters in the rear were all stunned. I don't even know what's going on.

The Southern Army was also dumbfounded.

"Poison, poison for sure, oh my God. It must be that the Chinese put poison in the shells, really fucking poison, the pale yellow smoke is poison. Your Excellency, what should we do? "A staff officer seemed to have something in mind. His face changed dramatically and he yelled at Sherman.

The NLD used sarin, though not the most powerful chemical weapon. For example, Soman, his toxicity is three times that of sarin, poisoning fast and no special antidote, but it is difficult to produce, under the technical conditions at that time, only as an experimental study, and sarin production is extremely convenient, the biochemical research institute of the Democratic Alliance has mastered the mature sarin synthesis technology as early as a few years ago, and has a large number of sarin shells in reserve.

Although VX is far more toxic than sarin, its toxicity mechanism is similar to mustard gas, mainly in the form of liquid droplets to cause damage to the enemy, rather than sarin's aerosol, which is generally used on polluted water sources and soil.

The shells came in bursts, and the smoke became thicker and thicker, slowly blowing to the west under the easterly breeze, and in the foggy weather, the air had a large water content, and the poisonous fog combined with water vapor formed fine molecules, and the weight increased, which could be stably suspended in the air, and it was more difficult to disperse.

From Sherman's point of view, he saw a large pale yellow mist drifting slowly, and in the mist were stumbling soldiers, struggling and howling in despair, and the horses became frenzied, jumping and jumping with their hooves, and in the midst of a mournful neighing, many of them turned and fled.

Sherman's hands and feet grew cold, which completely upended his perception of weapons.

"I smell the fruit, oh, it's smelly, but how can my head be so dizzy? God, my eyes are starting to hurt! “

Although the yellow mist seemed to move slowly, in fact, the fine particles had already traveled far in the air, and even Sherman could smell the unique fruit aroma of sarin for a few minutes, and many people were already experiencing slight discomfort.

"Your Excellency General, hurry up and retreat!"

"If we don't leave, we'll all be poisoned."

The surrounding subordinates urged, "It's over, it's over, Your Excellency Lincoln is over, and the American Federation is over." Sherman, however, muttered to himself as if he had lost his soul, in fact he realized that the defeat of this battle would be extremely serious.

"Your Excellency, General, don't hesitate, retreat to the mountains to join General Grant first." Another man shoved Sherman.

Sherman came to his senses, looked left and right, and called with difficulty: "Retreat." ”

The soldiers of the Northern Army on the position fled back and forth frantically, and behind them was a wall of dark yellow smoke, as if death was chasing, yes, under the constant fire of the marines, the color of the smoke changed from pale yellow to dark yellow.

The speed of the first-class wind was about five kilometers per hour, coupled with the penetration of the diffusion agent and air carried by the shells, the speed of the pursuit was no slower than the speed of the northern army's rout.

The standard sarin shells of the Democratic Alliance Army, each containing 1,600 grams of sarin poison, fired a total of 12,000 rounds, a total of 19.2 tons of sarin poison, dumped on more than 20 square kilometers of land, and the human body will die within 1 to 15 minutes after inhaling 55~100 mg/min/cubic meter or 1.7 grams in skin contact.

When the yellow fog gradually dissipated, the ground in front of it was a dead silence, scattered corpses everywhere, people, horses, cats, sheep and livestock, cats, dogs and mice, squirrels, foxes and other small animals in nature, and some birds, it can be said that there is no living creature where Shalin passed.

Looking at the hellish scene, the Southern Army did not have the joy of easily destroying the Northern Army, but also felt a chill in his heart, and looked at the Chinese comrades-in-arms around him with some fear, this is simply killing people invisibly.

In fact, being killed by bullets and being poisoned by poison gas is a death, and being poisoned to death can also leave a whole corpse, but perhaps the soldiers have become accustomed to the noisy way of dying and enjoy the joy of killing the enemy with their own hands, for this kind of large-scale and quiet collective extermination caused by unknown poisons, it will be extremely uncomfortable, Wang Feng is also very puzzled by the reaction of the Southern Army.

At this time, Ewell asked in a trembling voice: "Your Majesty the Emperor of China, are you ...... All dead? Shall we send someone over and have a look? ”

Wang Feng waved his hand helplessly: "I can't go over now, at least I have to wait until the yellow fog dissipates, it seems to be raining this day, the wind will rise when it rains, and the fog will be blown away, and then I will let people monitor it at any time, tomorrow, tomorrow morning send someone to clean up the battlefield, there should be no problem." ”

"Good...... Good, good! Ewell stammered. (To be continued.) )
