After the flare exploded in the air, a large amount of smoke from the violent burning of white phosphorus appeared in the sky like silver lightning. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Here, Lu Jiayu, the chief officer of the Fourth Army of the Praetorian Guard, who was on the way, was sitting on an ironclad four-wheeled carriage and looking at the sky in the distance with a monocular.

In this vast grassland, the field of vision is extremely wide, but it is also difficult to find landmarks, if it were not for the pre-agreed direction and compass, Lu Jiayu would really worry that his Fourth Army and the Third Army would lose contact on this grassland.

At this time, he also happened to see the white phosphorus smoke appearing in the sky, and he also understood that the Third Army was already retreating, and a large number of enemy cavalry was coming.

"The engineer battalion immediately set up barricades, the flying battalion prepared the incendiary packs, the cavalry battalion two battalions went to meet the third army, the artillery battalion was in position, and the four infantry battalions were ready to fight!"

Lu Jiayu immediately issued an order, his Fourth Army is a complete mixed infantry corps, the main force of 20,000 people, its combat effectiveness is only slightly worse than the first army of the same infantry corps, the reason for the poor is mainly because his grassroots officers are mainly the third phase of officers, but compared with other officers of the Ming Dynasty, they are still relatively strong, at least in terms of discipline and execution of orders, they are not comparable to other classical armies.

As soon as Lu Jiayu's order was issued, the engineer battalion immediately carried a large amount of glass shards to a hundred paces ahead, and began to place glass shards in an open area fifty paces in front and behind, and two hundred paces wide.

At the same time, yellow road signs were placed on both sides so that the withdrawal of the Third Army would not be hindered by glass barricades.

At the same time, the artillery battalion also began to adjust the artillery on the four-wheeled carriage and measure the position of the white phosphorus when it burned, but a quarter of an hour before the launch, the commander of the artillery battalion also fired a white phosphorus bomb to inform the Third Army of the Janissaries that the bombardment was about to begin, and that it should speed up to avoid being injured by its own artillery fire.

A large amount of methane gas produced by the Royal Academy of Sciences through microbial fermentation ignited in a special device, and a large number of violently burning flames were immediately produced after the explosion of hot air balloons and pedal aircraft, and a large amount of methane gas was also taken into the sky.

These flammable gases are mainly methane, but not only methane, but also a small amount of hydrogen sulfide and sulfur dioxide, etc., which are produced by fermentation of a large number of mixed bacteria in pig manure, that is, methane bacillus that can mainly be fermented and produced by fermentation of methane bacilli such as brewing grains and vinegar grains.

These gases are collected from the huge glass and porcelain jars that are fired (iron cans are not used to avoid gas explosions due to frictional sparks during transportation)

On the march, the gas is collected into a paraffin-coated cotton bag, which enhances the airtightness and can be used as an explosives pack.

The Flying Battalion took to space with incendiary explosives filled (not fully filled) with methane and other flammable gases, while foot-operated personal vehicles began to prepare to fly into space, armed with bows and arrows and ignition devices.

At this time, Mutar had gathered 20,000 elite cavalry and surrounded the 15,000 cavalry of the Third Army, and they had a great appetite and were ready to annihilate the Third Army of the Praetorian Guard by outflanking them left and right, so as to repay the hatred of their people for being slaughtered by the Third Army.

However, the Third Army escaped slippery like a loach, and as soon as they saw the same white smoke bombs, Ao Bai and the others immediately turned around and pulled out the Apocalypse three-style flintlock pistol at their waists, fired and loaded them, and in one go, they overturned the projectiles in the sky towards the pursuing Khalkha cavalry.

The Khalkha cavalry, who were caught off guard, did not expect that this Ming army, which had only known to escape, would suddenly stop and counterattack so quickly, and many Khalkha cavalry who rushed too fast fell directly to the ground.

But by the time Mutar reacted in time and outflanked him from both flanks with his cavalry, Ao Bai and his Third Army had already taken advantage of this gap to run a longer distance.

"Cunning Ming Dog!" Mutar couldn't help but be furious, brandishing his scimitar and speeding up, but who knew that at this time, suddenly there was a loud cannon sound, and he could see countless iron bullets like heavy rain pouring down.

These high-speed iron bullets were like plowshares, and they plowed the originally orderly Khalkha cavalry through several bloody paths, and countless men and horses were smashed into meat pies.

That's not all, when this Mutar and his cavalry braved the artillery fire to finally catch up with the Third Army, a large dark cloud suddenly appeared overhead, and when he looked up carefully, it was not a dark cloud, but a huge cotton bag.

Mutar didn't know what this guy was, so he directly ordered his cavalry to shoot a few arrows first.

The Khalkha cavalry had a strong archery ability, and the height of the arrows reached was no less than the height of firing rifled guns at the height of white phosphorus bullets, but Mutal and his cavalry were surprised to find that these cotton bags were too soft, and when the bow and arrows came, he was easily and quickly ejected into a nest, because the impulse of the bow and arrows reached this height was severely reduced due to air resistance, so that the cotton bag was not only not punctured, but also naturally flew up.

At this time, the soldiers on the hot air balloon will throw a large amount of water at these cotton bags, and the cotton bags will increase the gravity because they are soaked, and they will quickly fall, and as soon as they get close to the head of the Mutar cavalry, the soldiers on the pedal aircraft will decisively shoot the rockets up.

At this time, the airtightness of the paraffin wax decreased due to the wetting of the cotton cloth, and the flame on the rocket instantly detonated the gas in the cotton bag, and a large amount of methane gas quickly burned into a fireball and sprayed everywhere.

The heads of a large number of Khalkha cavalry were burned directly to charcoals, and even the horses were burned, and the people and horses were very painful.

The Khalkha cavalry were stunned, they had never expected to be attacked from the head, and many of them were already frightened, although there were still cavalry rushing towards the forward positions of the Fourth Army, but most of them were only inertia.

Mutar endured the burning pain on his face (burned) and rushed towards the Fourth Army with the remaining more than 10,000 cavalry, in his opinion, since he couldn't clean up the Ming cavalry that ran faster than a rabbit, it was not more than enough to clean up this infantry.

But he soon realized that he was wrong, for as soon as his cavalry rushed in, he heard the fierce wailing of the horses, and many of them began to retreat consciously.

Mutar was surprised to find that the cavalry horses on his side were stained with blood, he naturally didn't understand what was going on, so he could only whip the horse vigorously to make the horse attack quickly, but the horse was not really without intelligence, and the things that had just pierced their horse's paw or horse's foot made them dare not venture forward.

At this time, seeing that the cavalry formation of the Khalkha Department had been greatly disorganized, and even the horses were cramped because of broken glass, Ao Bai led two cavalry battalions of the Third Army and the Fourth Army to outflank from the left and right.
