Soon, the first weapon order of the scientific research institute was successfully completed under Yushu's gratitude.

A total of ten first-generation Shenwei cannons and a hundred shells, as well as three hundred first-generation arquebuses, and 10,000 rounds of ammunition, although it doesn't look like much, it should be able to fight a small-scale local war.

Yushu paid 200,000 taels of gold for it, and it was necessary to complete the installment payment within half a year.

Zhao Heng is naturally not afraid that the other party will repay the debt, just with the three thousand firearms battalion in Baiyucheng, he is absolutely sure, he can easily take a small Tu'an country, and if he dares to repay the debt, he must be ready to be destroyed, although this is a matter of time.

The reason why Zhao Heng asked Yushu to pay in gold was because he had to prepare for the gold reserves needed to open a bank in the future.

Moreover, he should implement the bank and the currency reform at the same time.

With the beginning of the use of steam engines and the emergence of various new lathes, the manufacturing speed of artillery and muskets has been accelerated several times.

In addition, the requirements for the craftsmanship of the first generation of Shenwei cannons and the first generation of arquebuses were not particularly high, so it only took half a month for the military factory in Baiyucheng to complete this order.

Almost at the same time, the 3,000 firearms battalion in Baiyucheng had basically been reloaded.

Each person has a rifle and 100 rounds of mini bullets, as well as the latest version of the Qi family knife, plus a hundred second-generation Shenwei cannons, as well as all kinds of shells, what sub-munitions, flowering bullets, etc.

It can be said that the three thousand firearms battalions in Baiyucheng now, in terms of lethality alone, are basically far beyond this era, even the elite crossbow array of the Qin army is difficult to compare.

As rifles and mini bullets continued to be manufactured, the Great Qin army would gradually reequip its entire staff until firearms were completely outlawed from cold weapons.

And at that time, Daqin's pace of conquering the whole world will be unstoppable.

……

At the beginning of August, one day.

Under the auspices of the Ministry of Rites, the first emperor Yingzheng offered sacrifices in the Taimiao, and then issued an order to send troops to Tu'anguo.

The battle order stamped with the seal of Yingzheng and Zhongshu Province was also sent to the Ministry of War and the Ministry of War.

Next, the military headquarters began to deploy logistics materials, and the military headquarters began to formulate battle plans and gather soldiers and horses from various battalions.

Although Zhao Heng has not completely implemented the military reform, in order to facilitate management, he still carried out some changes.

For example, all the current soldiers and horses of Great Qin are collectively called the army, and there are cavalry, foot soldiers, and crossbowmen.

Among them, the foot soldiers and crossbowmen were all in the army of five people, and the commander of the army was one man; The second army is what, and the chief is set up; Five tithes for the tun, set up a tun chief; Two tuns are hundreds, and one hundred generals are set up; five hundred, five hundred masters; A thousand, two or five hundred lords and one man, these have not changed.

However, in this establishment, 3,000 new personnel have been added to one battalion, with one lieutenant and two deputy lieutenants, which are the basic combat units.

The cavalry is five cavalry and one chief, ten cavalry and one officer, one hundred cavalry and one rate, two hundred cavalry and one general, and the new five hundred cavalry is a battalion, which is also a basic combat unit.

In order to strengthen the combat effectiveness of the cavalry, Zhao Heng also asked the manufacturing department of the scientific research institute to create enough horseshoes, stirrups, and saddles.

In the future, when the crossbow is fully reequipped, it can be directly transformed into artillery, or even a future long-range fire unit.

As for the cavalry, it can also be transformed into a tank unit of the future.

Although the dispatch of troops to Tu'an was nominally to help Tu'an resist the invasion of the Xiongnu, it was actually to take this as a starting point and begin to take the first step of Great Qin's conquest of the world.

The Xiongnu will definitely be destroyed, and as for Tu'an, I believe they will make a wise choice in the end.

……

On the 3rd, five infantry battalions, five crossbow battalions, and two cavalry battalions, totaling more than 30,000 people, were assembled outside Xianyang City.

In the afternoon of the same day, under the leadership of Wang Ben, the Marquis of Tongwu, the army accompanied Princess Yushu and her party and marched into Tu'anguo.

Two months later, the 3,000 firearms battalion led by Han Xin joined the army.

Three months later, with the sound of artillery, a major war broke out between the 50,000 combined forces of Daqin and Tu'an, and the 70,000 troops of the Xiongnu.

"Put!"

"Boom, boom......"

"Put!"

"Boom, boom......"

"Put!"

"Boom, boom......"

After three rounds of artillery bombardment, the Huns' cavalry battle formation was basically dispersed.

"Smack, smack, slap......"

This was followed by a queue to be shot.

At the West City Gate, under the command of Han Xin, the 3,000 firearms battalion stole almost all the limelight.

The 20,000 Huns who frantically attacked the city experienced first-hand what it means to suppress firepower.

Almost every cannon sounded, at least a dozen Hun soldiers were killed, and the death was extremely tragic.

In addition, 3,000 rifles, almost non-stop shooting, made it impossible for the Hun army to get close to the city gate for half a step, which can be described as a one-sided massacre.

And the other three city gates, although there are no firearms battalions, there are 30,000 Great Qin elites, plus more than 10,000 soldiers in Tu'an Kingdom itself, there is no problem at all to defend it.

Even, according to Wang Ben's idea, it was enough to go out of the city directly to defeat the Huns.

However, before the army marched out, Zhao Heng told him that he should focus on defending the city, and not end the battle too quickly, and it was best to make it a little more difficult to defend the city, or even a protracted battle.

Zhao Heng also said that war is a continuation of politics, and sometimes, it is not a good thing to fight too well.

Although Wang Ben didn't understand this sentence very well, he still kept it in mind and resolutely implemented it.

Zhao Heng actually knew very well that the Xiongnu in this era were far less fierce than those of later generations, and they had always been beaten by the Qin army to hide in Tibet, so to speak, even if there was no firearms battalion, the 30,000 Qin elites led by Wang Ben could easily repel the Xiongnu army.

But if he really did this, he wouldn't be able to let Daqin get the most benefits.

The divine might of the firearms battalion not only frightened the Xiongnu army, but also the soldiers of Tu'an.

Even the head of the Tu'an Kingdom, who was personally sitting at the head of the city, was so frightened that he couldn't speak.

Is this the power of the Heavenly Power Artifact?

It's horrible!

It's just that why do the Tianwei artifacts he bought from Anguo seem to be far less powerful than these?

"Father, we are saved!"

Yushu, who was standing behind Ba Yan, said with some joy and excitement.

"Are you really saved?"

Ba Yan was pale and muttered very unoptimistically.

Great Qin is so strong, and now with the help of the Heavenly Power Artifact, it can be called an invincible Heavenly Army.

After repelling the Xiongnu, where will Tuan go?

Ba Yan's gaze turned, and after carefully scanning Yu Shu, he didn't know what he thought, and his eyes became brighter and brighter.

According to Zhao Heng's protracted war policy, Wang Ben ordered the whole army to defend the four city gates, even if the Xiongnu army temporarily retreated, there was no intention to go out of the city to pursue, and even vaguely reminded Han Xin that firearms should be used in a restrained manner, so as not to waste ammunition.

As for the battle situation here, Zhao Heng, who was far away in Xianyang, was actually not very worried.

What he is most concerned about now is the construction of the railway.

Because if you want to move troops and supplies in a short time, you have to use trains.
