Nowadays, the "Diash" gunpowder produced and used by the Armament Institute has far exceeded the black powder produced under the supervision of the Gunpowder Bureau of the Ministry of Industry. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Speaking of which, the raw material formula is basically the same as the raw material and formula used by the Gunpowder Factory of the Gunpowder Bureau of the Ministry of Industry of the Ming Dynasty, but it is more careful in terms of process, ratio and purity.

At this time, the craftsmen and craftsmen of the Ming Dynasty were not much worse than the colonial powers such as Portugal, Spain and the Netherlands, in fact, the difference was the excellence in craftsmanship, and the strict management and sense of responsibility of each link.

For example, in the production of gunpowder, the use of higher purity nitrate and sulfur is, of course, more explosive energy can be produced than the use of nitrate mixed with soil and sulfur containing countless impurities, and the power of black powder has increased exponentially.

Although it is not as powerful as the various types of explosives in later generations, the explosive power generated by high-performance black powder is also not to be underestimated.

At this moment, the thief army in Shimen Pass was suffering from the ruthless killing of such a grenade made of black powder.

After all, the thieves who were directly hit by the explosive iron pieces and died were a minority, and more were injured and screamed by concentrating on non-vital parts.

Therefore, after Li Bei and others lit and threw four rounds of a total of 200 grenades on the top of the north peak of Shimen Pass, the thief army above the gate of Shimen Pass had already fallen, rolling, dodging, and howling.

Li Bei, who was high above, only heard the chaotic shouts, and watched the thief army below scurrying around like ants on the city, for a general like him who was used to fighting and seeing the dead, he had already trained a hard-hearted heart, and what he wanted was only victory, only merit, and only a wife who could be seen and touched, so he had no mercy for the tragic situation of the thief army at the head of the city below.

After throwing a few rounds of grenades, Li Bei gave an order: "The grenadiers come forward!" I took aim and dropped a fire bomb! ”

Li Bei has been in the army for many years, and of course he has seen such a thing as fierce fire oil, so he is still not used to the new name of the incendiary bomb, and always calls the incendiary bomb a fierce fire oil bomb.

However, this did not affect the choice of the mine grenadiers, who all knew what a fire bomb was.

Soon, dozens of black clay pots were thrown down from the top of the north peak of Shimen Pass, some smashed on the top of the thief army's head, and the thief army who was smashed was killed on the spot, and then fell on the stone slab of the Guancheng, which was immediately shattered, and a pool of black silk viscous liquid flowed out, exuding a pungent and choking smell.

Of course, more fierce oil clay pots fell directly on the stone slabs of the castle and shattered.

The black long-handled iron ball that was supposed to explode was gone, and suddenly so many clay pots fell from the sky and shattered when they landed, Liu Guocheng, who was standing on the other side of Guancheng and commanding, was a little dazed and didn't know what was going on.

However, he soon knew what to do, because as soon as the torches that fell from the sky landed, the part of the city that was stained with those black sticky things immediately burst into flames, burning and spreading, emitting a pungent black smoke.

There was no wood, no firewood, and the black liquid flowed slowly on the stone slabs, pushing the fire towards the city.

Those thieves who were splashed with fire oil quickly turned into fire men, and those thieves who were originally injured by shrapnel and containment from grenades, as well as people who were too close to dodge, also quickly fell into the flames, and many people desperately moved down the city in order to avoid the flames, but the outcome was the same, but the difference between burning to death and falling to death was the same.

Taking advantage of the chaos when the stone gate was closed, Lu Xiangguan, who was ordered to command the thief soldiers in the camp to push the siege tower cart to advance slowly, immediately led his men and horses forward, and kept whipping the thieves who were cowering and not working hard enough, driving them to push hard.

The siege carts were very tall, and they were all newly cut logs, and there were ten or even twelve musketeers standing in the watchtowers above each cart, so each cart was very heavy.

Although it was equipped with four huge wooden wheels, it was very difficult to move forward, and the creaking sound, accompanied by the howl of the city, and the explosion of grenades, enveloped every place above and below the stone gate.

The chaos at the head of the city had been going on for most of the hour, and the twenty-four siege carts had finally advanced with difficulty to within the range of the bandits at the head of the city.

However, only a part of the thieves at the head of the city could still play a role near the southern section, and the arrows shot down, and the thieves who were dragging the building cart in front fell instantly, making many of the soldiers stop quickly, and many of the building carts finally stopped moving.

Lu Xiangguan waved his knife and scolded in the back, but there were constantly chaotic bows and arrows shooting down at the head of the city, allowing Lu Xiangguan to scold, and the people walking in front just didn't dare to step forward, hiding behind the building car, avoiding the rain of arrows.

Lu Xiang was in a hurry to see it, and rushed forward with the left and right guards, but suddenly a rain of stones fell from the sky and hit his helmet and knocked him to the ground.

None of the soldiers who were behind him with shields did not follow, which caused such a consequence, and several people hurriedly stepped forward, covered him with shields, and carried him back against the rain of arrows and falling rocks.

This rain of falling rocks and arrows came from the camp of the thief army on the south peak of Shimen Pass.

As the siege carts of the official army entered the range of the thieves at Shimen Pass, the camp of the thieves on the south peak of Shimen Pass finally began to play a role, and the rain of arrows and falling rocks kept moving towards the siege carts in front of Shimen Pass, as well as the people in front of the carts, that is, the thieves who were only captured by the thieves who were incorporated into the camp of the baggage craftsmen in the past few days.

The dozen or so siege wagons near the south side of Shimen Pass finally stopped their wheels that were moving slowly forward before with a creak, because the hundreds of thieves and prisoners in charge of the carts suddenly shouted and ran back.

More than a dozen building cars were left standing on the open ground in front of the pass, bearing the rain of arrows and falling rocks from the top of the south peak of Shimen Pass.

Fortunately, these siege engines were equipped with wooden planks to cover the musketeers hidden inside, so as long as they were not hit by boulders, they would have to die in a short time.

The offensive and defensive battles of Shimen Pass soon became less relevant to the people inside and outside the pass, and the key to everything depended on how to better play their role in the two heads of the north and south of Shimen Pass.

Li Banghua stood in front of the official army camp, holding a monocular clairvoyant and looking at the smoky mountain peak on the south side of Shimen Pass.

Although the hill on the south side is lower than the one on the north side, if there is a cannon erected on the north side of the hill, then everything is easy to say, you can use the Chongzhen rear-loading smoothbore mother cannon with a long range to suppress it, but unfortunately, the weight of such a gun improved by the Fran machine is still too large, each weighing 800 catties, in the current situation, the difficulty of transporting it to the top of the north peak is not less than simply sending people to attack the south peak.

While Li Banghua was playing the idea of the southern peak of Shimen Pass, Liu Guoneng was also on the other side of the city, looking at the north peak of Shimen Pass in a daze, and he must not let the officials and soldiers throw firearms down from it anymore, or at least they can't be allowed to throw firearms down so unscrupulously and unscrupulously.

Li Banghua was still pondering and meditating on countermeasures, and Liu Guoneng had already begun to dispatch troops to attack the top position of the North Peak of Shimen Pass.

This time it was Liu Wengui, who was supposed to be in charge of this direction.

As Liu Wengui led a large number of men and horses to attack the top of the northern peak of Shimen Pass from the gentle slope on the west side, Li Bei and his grenadiers, as well as the musketeers who stayed behind to protect the grenadiers, soon felt the tremendous pressure from the bandit army on the western slope, and they all turned around and began to surrender grenades and incendiary bombs into groups, surging like a tide of thieves.

As soon as Li Bei and others on the north peak of Shimen Pass stopped attacking the thief army in Shimen Pass, Liu Guocheng on the gate regained his vitality and soon ordered the defenders of Guancheng to push down the thief army who had been killed and injured, burned to death, burned, or even trampled to death and injured because of crowding and stampede, from the top of the city, and then made room for extinguishing the fire.

Because there was no follow-up fierce fire oil, there were no other easily burning objects on the castle except people, so it didn't take long for the fire at the head of the city to become smaller, and after more than an hour, it finally burned out and extinguished.

The thief army who was once again caught up by Liu Guoneng in Guancheng cheered, and then picked up their bows and arrows and began to shoot arrows at the nearest siege tower car.

Naturally, the officers and soldiers in the building car were not to be outdone, and they shot back one after another.

The battle in front of the Shimen Pass, just like that, once again fell into a stalemate.
