Guo Peng knew that it didn't make much sense to make gunpowder now.

Without supporting steel production capacity and forging technology, gunpowder did not have much actual lethality to boast of.

But at this moment, what he really needed was not the lethality of gunpowder, but the sound and resonance of the explosion of gunpowder.

Horses are animals and can be frightened, people are also animals, and they can also be frightened, and suddenly a violent explosion that they have never seen before is happening around them, and a violent sound is sounding around them, how will they react?

However, this requires extremely precise calculations and training preparation.

The opponent is a light cavalry, good at cavalry archery, they will use cavalry archery to attack the Han army, not as easy to deal with as the Yellow Turban Army.

Although the core of the tactics has been prepared, it is obvious that there will be a lot of time to prepare for how to use gunpowder to achieve the final victory.

The thin iron shell and gunpowder of the earth-shattering thunder are ready, but there is still a lack of leads, and others can't get the leads, and Guo Peng really has a batch of paper made by himself around him.

It's not much, but it's enough to save a little.

Cut the paper into long strips, dip the stone powder with a stick, shake it, and the stone falls on the paper strip into a long strip, and then directly knead the paper into a thin strip, and then stain the rice milk with your hands, a hand, and then dry, it becomes the simplest lead.

When everything was ready, Guo Peng found an uninhabited valley west of Ning County and began experiments.

There were thirty earth-shaking thunderbolts in the first batch, and Guo Peng used these thirty earth-shaking thunderbolts to test the effect of the explosion, the sound, the speed of the fuse burning and the success rate of the explosion.

The first test began in January, followed by three more in February, and by the time the news of Kazuen's southward movement was learned in March, seven tests had been completed, and an attempt was made to tie the earth-shattering thunder to the arrow and shoot it out with a bow to achieve a long-range attack.

Anyway, Cheng Li definitely didn't expect Guo Peng to be working on this new weapon, and after seeing and hearing it with his own eyes, he was very surprised, and asked Guo Peng about the reason very pleasantly.

Guo Peng casually made up an excuse, and then explained his tactical ideas to Cheng Li, Cheng Li did not doubt that he had it, saying that with such a sharp weapon, this time the battle situation would have a chance of winning.

Nomads fight with bravery, and once they break up, they will break up like a rabble, and when they encounter something incomprehensible, they will think about ghosts and gods.

When the time comes, spreading some rumors will make the Xianbei Xiongnu and Karasuma people who don't know the truth scared to fight Guo Peng.

Cheng Li participated in the design of the earth-shattering thunder tactics, planned the essentials of use for Guo Peng in detail, and the two also calculated some distances, explosion times and counterattack points together.

The main force of the Han army maintained a full cavalry line-up, and the 2,000-foot army was responsible for forming a formation, and carrying a large number of bows and crossbows out of the fortress together, to meet Helian on the endless prairie, and set up a face-to-face formation with Helian on the vast prairie.

Guo Peng put on the Xuanjia, mobilized fifty of the most powerful soldiers and also equipped the Xuanjia, formed a stormtroopers, and decided to personally charge into battle and lead the whole army to defeat the enemy.

This is the battle of his own prestige, and if he wins this battle, it will be much more convenient to do things in the future.

This battle must be won!

On 11 March, all the sentries sent by Guo Peng to seek the enemy rushed back and reported to Guo Peng the movements of the cavalry of the company.

At the same time, the Xianbei leader and the company also knew that Guo Peng led the army out of the fortress to take the initiative to meet the battle, he found out Guo Peng's troops, and learned that Guo Peng only brought 5,000 soldiers and horses to challenge him, and the company and a group of generals laughed in unison.

"There is no one in the Han Kingdom! actually pulled out a boy who didn't know how to soldier, these 5,000 people wouldn't all be boys, right? Hahahaha! ”

Another burst of laughter.

After laughing, and Lian's face was full of bloodthirsty desire.

"Kill all these 5,000 Han people, and then loot them once!"

He Lian's words aroused the widespread approval of the generals around him.

In fact, Helian went south not only for looting, but also for his own purpose.

After the death of his father, the three major Xianbei tribes, which were originally united, showed signs of separation to varying degrees.

He did not have his father's great feat of defeating the 30,000 cavalry of the Han Chinese, and no one wanted to listen to him sincerely, so he tried his best to stop it, but he could not stop this trend.

Although he is still the leader of Xianbei, except for the royal court of Danhan Mountain and some forces belonging to the central Xianbei, most of the people are in a state of listening to the tune and not listening to the announcement.

So Helian desperately needs to prove himself.

He spent a lot of time in order to stabilize his position before, but now that his position is stable, he needs greater military exploits to pursue greater power.

Martial arts are always the best way, and prestige is gained through meritorious service, and prestige directly brings power, which is what Tan Shihuai said.

At this time, He Lian was pleasantly surprised to learn that the new Captain Gokarsuma sent by the Han Dynasty was a twenty-year-old young man, and he felt that he had found a way to success.

Guo Peng is the stepping stone on his road to success, destined to be killed by him in exchange for prestige.

So when he learned that Guo Peng took the initiative to lead his troops to challenge him, He Lian was very happy, and felt that he finally didn't have to spend time attacking the city, the Han city's city was really troublesome, and it was too difficult to attack.

Early in the morning of 13 March, there was an encounter between the Xiahou Yuan and the Helian forwards of Guo Peng's department, and the two sides fought for a while, each with casualties, and quickly retreated.

At noon, Guo Peng saw from a distance that a dense black pressure appeared on the skyline, and a large area of cavalry was pressed, and the array that was not so standard slowly came in the direction where Guo Peng was.

Guo Peng looked around and saw that it was a vast prairie, so he decided to use this place as a battlefield.

"Foot soldiers! The horsemen blocked the horse's ears with a cloth ball! ”

Guo Peng ordered the cavalry of the whole army to plug the ears of the war horses with cloth, and then a group of cavalry dismounted, holding bows and crossbows behind the shield soldiers and spearmen.

The foot soldiers lined up the cart brought by Guo Peng in a circle, the shield soldiers put the shield on it, and the spearmen set up the spear behind it, the body of the spear sticking out of the shield, and the tip of the spear flashed with a cold light.

It didn't take long for a complete defensive counterattack formation to be formed.

"Is that Guo Peng's army?"

"Yes, their banner is Captain Guo."

He Lian and his cronies confirmed the identity of the commander of the Han army opposite.

He Lian looked at the place where the Han army was arrayed from afar, and saw that the Han army had a complete lineup, a standard army formation composed of carts and shield pikemen, and there were cavalry in the military formation, but the number was too small, and it seemed that it was not enough to fight by himself, and he felt very happy.

This boy probably doesn't know what cruelty is, and he is not very good at fighting, and he dares to go out of the city to fight with fewer soldiers and horses than himself, and it seems that because he was not the one who was wiped out by the whole army back then, he was bold.

In recent years, the Han army has not dared to go out of the city to fight.

Teach him what cruelty is and what war is.

He Lian looked at the sky and said to the people around him: "Let's end it as soon as possible, tonight, we can stay in the Han city for the night!" ”

The cronies around him are very excited.
