Seeing that the routed troops of the Houli Dynasty fled into the city, Li Guo did not attack and did not besiege the city.

Li Guo didn't want to besiege Nantai Taiyuan City, that would turn the battle into a tough battle, because then his own people might suffer very severe losses, which Li Guo didn't want to see. Moreover, the siege will be a protracted war, and the consumption will be too great.

Therefore, Li Guo just stationed his soldiers and horses in one place to give Zheng Mian a chance to evacuate, and of course, ambushed soldiers at the place leading to Shenglong, the capital of Houli.

The next day, there was no movement in the city.

Li Guo looked at the city head of Nantaiyuan, frowned, and turned to look at his elephant. These elephants were encircled, and most of the elephant soldiers who were responsible for training the elephants were replaced by Li Guo's soldiers.

Li Guo took a look, and there was a person who noticed the elephant more than Li Guo, Song Yingxing.

Seeing that Song Yingxing couldn't put it down, Li Guo asked, "Yingxing, do you like this thing too?" ”

Song Yingxing nodded: "This thing is good!" I'm Pondering" novel. I want to bring them back to Guangxi, this thing has a lot of strength, and some projects can be used. ”

Li Guo smiled, "It's okay to give you a few, but it's not okay to have more!" They're still of great use. ”

And one after another, Liu Tichun, Li Twelve and others also came to see the rarity, these people had never seen an elephant before.

Li Guo had breakfast with everyone.

During the banquet, Song Yingxing said: "If these elephants are equipped with crossbows on the back of elephants, the effect should be good." ”

Li Guo nodded, "I want to load a cannon on the back of an elephant!" What do you think? ”

Everyone shook their heads and said that it must not work. As soon as the cannon is fired, let alone killing the enemy, the elephant goes crazy first.

Li Guo smiled and gave Song Yingxing a task. That is to make the elephant not afraid to fire the cannon.

Song Yingxing thought about it, smiled, and agreed, "Okay, it's a good idea, I'm sure to train you to be an elephant that is not afraid of the sound of cannons!" ”

Everyone was puzzled, and Song Yingxing explained, "Every day, firecrackers are set off in front of elephants, and a single small firecracker is set off first. After a while, small firecrackers are set off in a row, and the elephants get used to it. Slowly amplify the firecrackers, so that the elephants can adapt to the roaring cannons! ”

Everyone said it was a good idea, but it didn't always work.

Song Yingxing replied, you wait and see.

Song Yingxing's idea is also Li Guo's idea. The cannon at that time was heavy. It is also inconvenient to walk when there is a cart pulling a horse. If you can tame an elephant and attach a light cannon or a few small cannons to its back, then the elephant will become a mobile turret!

However, at the moment, it is not to train elephants, but to capture the South Taiyuan City in front of you.

Seeing that there was no intention of abandoning the city and running away in the city of South Taiyuan, Li Guo ordered Wang Si to take a part of the artillery wagons of the mixed brigade to fire a burst of artillery at the city of South Taiyuan. Luo Hu took a part of the cavalry and infantry to protect.

Li Guo's troops were only stationed at the north gate of South Taiyuan City, and the rest of the city gates were not blocked, but some rangers were sent to block them. Therefore, it was the north gate of South Taiyuan City that was shelled.

The north gate of South Taiyuan City was also the top priority of Zheng Mill's defense. Not only are there a large number of elite guards here, but the young and strong men in the city are also defended by rolling wood and stones. So there are a lot of people in the castle tower.

Wang Si stopped the gun cart and unloaded the red-coated cannon from the car. This is the only cannon in the entire mixed brigade that needs to be unloaded from the car, and this kind of cannon is so powerful that it makes a sound like a mountain shaking the ground.

The red-clothed cannon is also called the Hongyi cannon, which was originally aimed at the barbarian Jianzhou Jurchen outside the Guan, but it was called white and called the red-clothed cannon.

At that time, the largest red-coated cannon could even reach two tons, and the firing range could reach 2.5 kilometers.

Li Guo carried only an ordinary cannon of more than half a ton, and the effective range of this cannon was about 1,200 meters, and it could fire several kilograms of ammunition. The projectile is a spherical solid bullet made of stone, iron, lead and other materials, which is ingenious, has a variety of shapes and methods, and plays a destructive role by directly hitting the target, and can also occur chain bullets, etc., and has greater lethality.

But such a cannon is already quite powerful for the Houli Dynasty, because the Houli Dynasty has no artillery.

Therefore, the officers and soldiers of the Houli Dynasty watched in the city with a blank look at Wang Si commanding the erection of the fort. However, the soldiers of the Later Li Dynasty were not worried, because there were only eight of these guns in Li Guo's mixed brigade.

Wang Si raised the order flag and shouted, "Release!" ”

The eight cannons rang out almost at the same time, shaking Wang Si's ears on the side with a roar.

Eight huge pills roared past, swept past the city, and entered the city of South Taiyuan. A few houses and some pedestrians were directly destroyed, but they did not even touch the city wall.

Li Guo, who was watching the battle from a distance, scolded angrily, "Little Four, this little rabbit cub, how many times have I rehearsed, but I still can't tell you how to fight." Ying Xing, you go teach them! ”

Song Yingxing ran over and said to Wang Si, "Aim and fight!" ”

Wang Si's face turned red, and he hurriedly re-brushed the cannon chamber, reloaded the ammunition, and aimed at the city wall, and eight loud noises passed, and this time it was low, and it didn't even hit the root of the city wall.

It's no wonder that this kind of cannon has always been really combated, and it was basically done with some tiger squat cannons to fight Zheng Milling and Zheng Yu, when the enemy was close and the number of people was dense, one hit was accurate.

Seeing that he hadn't hit yet, Li Guo jumped up and scolded, "Even Song Yingxing is a stupid person, don't you know the principle of parabola?" Li Guo also smiled after speaking, how could they know the parabola.

Seeing Li Guo and the others coming on horseback, Wang Si began to hurry.

Li Guo jumped off his horse and said to Wang Si, "Don't pretend to be from there, come over with the gunners!" Song Yingxing also came over! ”

Everyone gathered around Li Guo, and Li Guo drew on the ground, a straight line, an arc, and talked about the principle of parabola with these uneducated people.

In fact, the cannon is equipped with a front sight and a light door, which calculates the trajectory according to the parabola, and the accuracy is very high. It's just that Wang Si and these guys are all born in the mountains, and Song Yingxing hasn't really gone through artillery battles, so the two rounds of artillery are crooked.

Li Guo didn't tell them anything about the focal chord length of the parabola, and explained to them the trajectory of the shell in the simplest and most popular language.

Fortunately, these people are not stupid, and they can understand it at all.

Wang Si volunteered to adjust the height of the muzzle of the cannon himself.

Li Guo scolded on the side, "Little Si, if you hit this round of cannons crookedly, Lao Tzu will stuff you into the barrel of the cannon!" ”

Wang Si also knew that Li Guo was joking, and while he was having fun, he was seriously adjusting the crosshairs. After confirming that it was correct, Wang Si ordered the cannon to be fired again!

At the head of the city, the soldiers of the Houli Dynasty were watching the excitement, and the soldiers of the Houli Dynasty all thought that these things of the Ming Army were very bluffing, but they were useless at all!

At this moment, a roar came, and the people at the head of the city suddenly realized that the cannonballs had been fired at them! The crowd panicked. In order to avoid the cannonballs, there was a soldier in the back who was dexterous and jumped from the city, and he jumped badly, so he fell to his death.

Listening only to the loud bang and boom, eight shells accurately hit the head of the city, and suddenly, shrapnel and stones flew wildly, stumps and broken arms were all there, and two of them were directly hit by the shells and smashed into meat sauce.

Eight shells killed dozens of people, all of whom were blurred in flesh and blood.

More people were injured, and from time to time there were screams!

Li Guo laughed and praised, "Little four, play well, keep fighting!" Fight slowly, don't let the barrel heat up too much, let's not rush! (To be continued......)
