The materials have been prepared, although Wang Rong's heart is still very worried, but he did not flinch and stabilized his mind. Then the ingredients begin. The ratio of nitrate, sulfur, and charcoal in the dream is 6:1:1 and 15:2:3, and Wang Rong is not very clear about which one it is, so he matched two kinds, each of which was about one catty.

After making it, Wang Rong put two parts of gunpowder into two clay pots. He took Wang Mao and other guards to a clearing place, which was prepared for the expansion of the wounded soldiers.

Wang Rong placed the two clay pots behind the two stones that had been moved and lit them one after the other as a contrast. The question of how to light a clay pot from a distance is a problem. However, Wang Rong quickly found a solution.

He spread the sulfur evenly on the ends of several hemostatic bandages, about a foot each. One end is inserted into the clay pot and the other end is placed in the hand, so that several bandages form two ropes several meters long.

Wang Rong personally lit the rope with a fire breaker, and after waiting patiently for half an hour or so, two explosions finally came from behind the stone, and then smoke rose.

"Protect the Captain!" Wang Mo was so startled by the explosion that he hurriedly blocked in front of Wang Rong. Several guards armed with swords and shields formed a circle around Wang Wei and Wang Mao.

"Don't be nervous, come with me." Wang Rong pushed aside Wang Hao, who was blocking in front of him, and walked forward with a calm face. It was his first experiment, and he was really nervous, but he couldn't show it.

Wang Wei followed Wang Wei with a team of guards and came behind the stone. The stone is quite intact from the front, but it is different at the back, with large and small cracks all over the back of the stone, and several ceramic fragments inserted inside.

Wang Mo couldn't close his mouth in surprise: "Du Wei... This... Is this thing so powerful? ”

Wang Rong looked at this power, shook his head, and thought in his heart: The amount of gunpowder is too small, and the power is not enough. But it doesn't matter, you can add gunpowder. But how do you ignite it? It is definitely not possible to use fire directly, it is suicide.

Then his eyes looked at the bandages that had been burned beyond recognition on the ground, and an idea immediately came to mind.

"Wang Mao, arrange for someone to recycle everything here. Let's go back. After giving the order, Wang Rong took Wang Hao back to the tent where the gunpowder was made.

Since it is not possible to use a fire breaker, it is like igniting a clay pot with a rope. Wang Rong asked Wang Mo to find a lot of hemp rope, he cut the hemp rope into sections, and then found oil and soaked the hemp rope in it. The oil does not go out when it is exposed to water, so that on rainy days, it can also ignite the hemp rope soaked in oil.

Wang Rong hung the hemp rope soaked in fire oil on a long bamboo pole to dry, Wang Hao and his guards followed the work, and then everyone's hands, faces and clothes were rubbed with fire oil, one in the east and one in the west, like a beggar.

Wang Rong carefully advised: "Don't go near the fire, otherwise you will set your clothes on fire and go to get the spare clothes." Take off this shirt and put it away, maybe it will be useful. "In this era, there was no light oil, and clothes with fire oil stuck to it could not be worn at all.

Wang Rong then instructed: "We will continue to make this kind of clay pot, which must contain not only gunpowder, but also nails and something." ”

Wang Mo nodded, and quickly led someone to take the thistle terrestris, which is available in the military camp. Wang Rong changed to a larger clay pot, and put three catties of gunpowder and two catties of iron nails in it. Then seal it with wax, as long as the fire rope is dry, and plug the small hole left in the wax seal, and an earthen grenade is made.

"Captain, can this thing work?" Wang Mo asked suspiciously.

Wang Rong didn't know the bottom of his heart, but he couldn't show a trace of hesitation, and said: "If you can do it, you have to try to know." ”

Wang Rong took the guards to make gunpowder for a day, and made three or four hundred gunpowder clay pots, basically two for each of the guards.

When Wang Rong was lying on the bed in the tent of the Chinese army, he finally remembered that he was a wounded man. He did not lie down, but sat up, looked at Wang Wei standing in front of him, and said, "This gunpowder clay pot is top secret, let the brothers of the guards guard the tent." No one is allowed to approach it, and no torches or other sources of fire are allowed to enter the tent when entering to take it. ”

Wang Mo nodded, bowed and said, "I understand, Captain." He can see it, not to mention whether this gunpowder clay pot can kill the enemy, but there is so much gunpowder in the tent, and when it encounters a fire source, it is more ferocious than fire oil.

The night was fine, and the next day, before Wang Bian got up, he heard the rumbling drum in the distance. Wang Rong sat up with a brush, "Someone!" Armor! ”

Wang Mo walked in with two guards and removed the armor from the wooden frame. The damaged nail leaf has long been repaired by craftsmen, and a nail leaf has been added to the gap between the waist ribs.

Wang Rong quickly put on his armor, removed the "Ten Thousand Enemies" from the weapon rack, and carried the bear-pattern winch crossbow on his back, so that the quiver was no longer needed, and wooden barrels full of arrows were placed everywhere on the wall, which could be used at any time.

Wang Rong took the guards out of the Chinese military tent, and rushed to the wall, if someone looked closely, they would find that the guards had two or three more clay pots on their bodies.

Li Sujie stood at the head of the wall and said to Wang Rong, who came up: "Duwei, the Bearded people have launched an attack, and it seems that they are busy with a lot of work yesterday." ”

At this moment, Wang Rong looked out of the wall, and there were obviously a lot more siege equipment of the Bearded People, and there were hundreds of the most common flying ladders. They also built a very crude ladder truck, made of natural logs, with large gaps between the woods. In addition to flying ladders and cloud ladders, siege rams were also pushed out.

As for the large siege tower vehicles, due to the complexity of the technology, the manpower was too long, and the Bearded Man did not have the time to build it. It's not that it hasn't been made, it's just that it's not finished yet.

At this moment, in the big tent of the head coach of the beard, Yu Sheshi and An were holding a silk book tightly with both hands, this was Eagle Letter. The mane man disdains to use carrier pigeons to pass the letter, and the wolf and eagle on the grassland are the best companions.

After reading the contents of the silk book, Yu Sheshi and An stood up and paced back and forth in the tent, their faces looking very nervous.

How could he not be nervous? His own sister Kedun severely reprimanded him in a silk book, and expressed strong dissatisfaction with his delay in achieving results in the city. He also told him that the Khan's anger against him was close to a critical point. If Khan's anger value is off the charts, even if he is Kedun's own brother, Kedun will not be able to protect him.

Yu Sheshi and An had their own information channels, and when he was fighting with Guang Mucheng, the battle situation in the northern border of the entire Yongguo had changed. The troops of the Khan of the Qiang, who attacked Linwo County, were stopped outside the border wall by the Northern Army and the Pingbei Army. The Yongjun army relied on the fortifications of the side wall to block the army of 120,000 men. And the attack of the Bearded Khan was repulsed several times, and he also lost a lot of people.

The 100,000 troops attacking Yunzhong County were blocked by the Zhenbei Army and the Anbei Army on the front line of the barren water. They wanted to go west to copy the back route of the Northern Army and the Northern Army, but they couldn't. The Zhenbei Army and the Anbei Army gathered 30,000 cavalry, and as long as there was any change in the Bearded People, these 30,000 cavalry would be dispatched, like enough dog skin plaster, and they couldn't get rid of it.
