Yuan Shao is worthy of being the third prince of the fourth world, his cultivation is still very good, after doing a night of psychological construction, he did not directly let the army ants attach to the siege of the city, but cut down trees and build ordnance.

This made the inside and outside of Yecheng appear calm before the war.

Outside Yecheng, Yuan Shao looked at the sergeants who were building ordnance with axes, saws and hammers, and said to the people behind him, "This time, our army will mobilize 150,000 or 60,000 to attack Yecheng, all the soldiers must work hard, if you can kill Ma Qiang, I am willing to reward Jizhou to him!"

Even if the horse thief escapes, I will not hesitate to pay homage to the general. ”

Yuan Shao sprinkled a lot of wishes to stimulate the soldiers' fighting spirit, and at the same time sent people to constantly rush into Taihang Mountain, urging the follow-up grain, grass and gunpowder to be sent quickly.

Yuan Shao's upper lips and lower lips were ready to dispatch a large number of Montenegrin troops and horses to attack Ye, Chun Yuqiong in Shexian County and Xun Chen, who coordinated the transportation of grain and grass in Bingzhou, almost vomited blood angrily.

This grain and grass transportation is calculated everywhere, where can the demand suddenly double, not to mention that there is not enough food in the state, even if it is enough, it will not be played like this.

If you don't have food, you can see if we have a lot of meat, and if you have too much, you can pull it out and sell it.

Chun Yuqiong didn't dare to complain directly, anyway, as soon as he transferred to the station, he sold Xun Chen in Bingzhou, saying that it was because Xun Chen couldn't send enough food, which made it difficult for him to complete the task.

Yuan Shao understood what was going on at a glance, he thought about it, too, this grain and grass problem is a big problem.

All parts of Jizhou have been fortified and cleared, and Yuan Shao also sent troops to search everywhere, and the return was that it would be difficult to find food unless those county towns were attacked.

After Yuan Shao knew that Ma Qiang had a cavalry in his hand, he didn't dare to divide his troops, so he could only send someone to Hanoi and ask Fang Yue to come to help with soldiers, horses, grain and grass.

What Yuan Shao didn't know was that the two armies, with a total of 20,000 soldiers and horses, were ambushing at the junction of Hanoi and Wei County, and if it weren't for Yuan Shao coming up with such a big scene, they would have already entered Hanoi.

All in all, after Yuan Shao was busy coordinating the grain and grass, ten days had passed.

In the past ten days, Ma Qiang has not been idle.

He's designing a new weapon.

Looking at the two-basewood prototype made of bamboo as the main raw material in front of him, Ma Qiang nodded with satisfaction.

Well.... It's a little shabby, but it seems like this.

Of course, the design of a rocket is actually a complex work involving many disciplines, and even if the design and layout of the propellant are not mentioned, the shape and layout of the outer body of the rocket will affect the flight trajectory of the rocket after it flies out.

You don't see, the missile Brownian of the largest civilian cooking country next door is moving.

The shape of the rocket in later generations needs to be modified countless times after entering the wind tunnel test, and the one in front of Ma Qiang was drawn by Ma Qiang.

But fortunately, Ma Qiang now only needs this thing to fly out and explode in the crowd, as for the accuracy....

As long as you don't fly back.

Ma Qiang's rocket is designed to be about 1.5 meters long, and the gunpowder inside is divided into two layers, the inner layer is the warhead, and the outer layer is the propulsion department.

As for why black powder can be used as both a warhead and a propulsion part, one is that if there is a subtle change in the ratio of the three main components of black powder, its performance will change.

For example, if the content of nitrate increases, then the power and burning speed of gunpowder will increase, and when the content of potassium is constant, the less the proportion of charcoal, the less energy of gunpowder, and vice versa.

All in all, the chemical equation of gunpowder is indeed the same, but it does not mean that all gunpowder equipment needs to be matched according to the optimal ratio.

The second is that when the gunpowder is burned, as long as a large enough gas outlet is given, he will discharge a large amount of gas from the gas outlet to form a reaction force, which is also the principle of the two kicking firecrackers.

"This thing is much more convenient to build than artillery, and if there are enough of them and the enemy is very dense, a single attack can completely crush the morale of the enemy army." Ma Qiang asked Huang Xu, who was standing aside, "How is the situation with Yuan Jun?" ”

"Judging from the hot air balloon, Yuan Jun has built a large number of Lu Gong cars, rushing cars, rushing cars, ladders and throwing cars, and the attack should be in these two days."

"I'm not worried about what's on the ground, but what about the underground?"

"No tunnels have been excavated."

"That's good, you build thirty rounds of this rocket, and you can use it after the war."

The group of craftsmen agreed in unison and began to divide the work to build.

"Report! Ming Gong and Yuan Jun seem to have moved. ”

"What's the change?"

"Reinforcements came from the west, there were a lot of them, and they were in a steady stream, waving the banner of the Montenegrin Army."

"The Montenegrin Army? Wow, I'm afraid that the Black Mountain Army will not come out of the mountain, Huang Xu, you go and meet with Commander Xianyu, I think Yuan Shao is about to start attacking the city. ”

The news of Yuan's arrival soon spread throughout the city, and many of the people in the city began to worry.

"Pavilion Chief, although we are all from other places, this Wei County is now our Wei County, can you talk to the general and the envoy, let us also help."

"yes, it's good to help throw stones!"

Most of the people of Yecheng were immigrants, so it was clear that as long as Yuan's army occupied Yecheng, they would lose all their land.

After all, the original owners of these lands are all on the other side.

"That's right! Yuan's army has reinforcements, and our northern army also has it! We are the reinforcements of the Northern Army, and it is not a matter of sitting here every day to receive food and food, and everyone below will go with me! Go to the envoy and ask for battle! ”

Han Fu was coordinating with Wang Xiu the distribution of materials and grain and grass in the treasury when he suddenly heard a commotion, and when he asked, he realized that it was the people who had come to the city to take refuge and hoped to help defend the city.

"The hearts of the people are available! The people's hearts are available!! Wang Xiu patted his thigh and smiled, and although Han Fu's face was also smiling, there was also a hint of embarrassment.

When he was captured by Yuan Shao, he didn't see the people of Jizhou so willing to stand up for themselves.

Though... I surrendered on my own initiative.

But it's still delicious!

Wang Xiu, as the county guard of Wei County, immediately came forward and began to organize the people who were willing to help defend the city into a civilian team, thanks to the military training of the people in Wei County all the time, and the people adapted quickly.

Ma Qiang's judgment was correct, the next day, with the sound of earth-shattering drums and horns, a group of soldiers and horses came out of the camp of the Yuan army, pulling huge siege equipment with oxen and horses, and came to the west and north cities of Yecheng, officially announcing that they were going to fight.

Ma Qiang and Han Fu came to Xichengtou, and when they saw that Yuan Shao's handsome banner was also opposite, they knew that this direction was right.

Yuan Shao was on the opposite side.

Ma Qiang and Yuan Shao were both holding binoculars, and although they couldn't see where the other party was, they could both feel that the other party was looking at them.

Decisive battle! Let's go!!
