The heavy artillery of the Great Xia army continued to bombard the city walls, and the light artillery began to fire flat, bombarding the cavalry of the Western Army.

However, instead of raising his gun to aim, the musketeers took out a special firing crossbow. This is the same kind of crossbow that fired tear gas, but this time, instead of tear gas, the Great Xia Army shot Molotov cocktails.

It is also a fragile bottle, and when it is ejected, it will shatter when it encounters something, and then the gasoline and ignition device that are separated inside will meet, and then a violent flame will ignite.

This is the latest weapon developed by Chen Mu after getting gasoline, which is very useful against cavalry, or very useful against war horses.

Burning gasoline is difficult to extinguish, and can not only burn enemy soldiers, but also frighten horses.

Under the combined attack of artillery fire and Molotov cocktails, the cavalry of the Western Army was in disarray, the war horses ran everywhere, and the soldiers fled while undressing.

The Western Army, which was outside the range of flames, was also scattered by its own people and fell into a dilemma.

Chen Mu saw this situation and decisively ordered the musketeers to outflank them from both sides.

The musketeers of Bactria rode in electric tracked vehicles and fired at the Western Army, and occasionally the Western Army soldiers returned fire, which would also be blocked by the armor plates of the chariots.

The Great Xia Army was like a big broom, sweeping the Western Army in the direction of the city.

Seeing that the general situation was gone, the western generals in the city directly abandoned the Slavs and fled with the king.

An hour later, the day was bright, and the Bactrian army successfully occupied the Slavic seaside city.

The Westerners fled, which was also expected by Chen Mu, because the ships of Great Xia could not sail here, and they could not pursue them at all.

It is possible to bypass the continent from the north or south, but the distance is too far. As a lone army, the fleet cannot survive in the sea for a long time, and the slightest accident will be completely wiped out.

Moreover, Chen Mu was also worried that the fleet would encounter people from other countries in the process of driving, causing unnecessary trouble.

Therefore, in this battle, the only way to drive the Westerners away is to drive them away, and then slowly pursue them from the land.

Chen Mu ordered someone to clean up the battlefield, and then led someone to check the situation in the city. Chen Mu took people around and found that the city was very large, with more than 100,000 people living in it.

There is nothing of value left in the western country, just some backward equipment and materials.

Chen Mu asked the interpreter Urila to publicize the policies of Bactria and appease the masses, and then elected an elderly Slav as the king, established the Slavic kingdom, and then became a vassal state of Bactria .

Due to the damage of the war, the Slavic kingdom did not need to pay tribute to Bactria for three years, but only needed to worship according to the rituals.

And Great Xia would give a large amount of food to the Slavs, as well as other food, seeds, and daily necessities to help the Slavs tide over the difficulties.

But Great Xia is not a loss, the black soil here is the best arable land in the world, and it can be paid to Great Xia when the harvest is harvested in the future, and there are many iron mines here, which can build fortresses and factories here to defend against the Westerners.

Chen Mu arranged some more Xiongnu spies to publicize the benefits of becoming a subject state of Great Xia.

After doing these things, Chen Mu returned to the court, and the matter of building the fortress was handed over to others to do.

During the final general attack, the Great Xia army lost several electric tracked vehicles, but because Great Xia won the battle and had the power to clean up the battlefield, all the fragments were recovered.

What they don't know is that they didn't clean up.

Just after the Great Xia retreated, a Slav dug an engine out of a ditch.

He was very happy, because he knew that if he gave this to the people of the West, he would definitely get a great reward. He looked left and right, and quietly buried it again.

At night, he drove a wagon, dug things out and put them on the cart, and galloped away toward the west.

……

After Chen Mu returned to Great Xia, he began scientific research again.

While guiding the Academy of Engineering to research weapons, he and Long Xueyao studied trains.

In the laboratory, Long Xueyao asked, "Chen Mu, now that the oil supply is sufficient, why do you want to develop a steam train?" ”

Chen Mu explained: "Because the current engine is too simple and needs to be used with a generator, the horsepower cannot be too large. It is possible to drive a tracked car, but the train needs carrying capacity, not speed. ”

"Actually, Great Xia should have developed a train a long time ago, but it was delayed by the Westerners."

"You see, this train only needs one locomotive to pull more than a dozen carriages, and such a transportation volume is worth it."

Long Xueyao asked curiously, "To pull so many carriages, how big a locomotive does it have to be?" ”

Chen Mu smiled, "It's about the same size as the carriage." Because this train does not run on the ground, but on the tracks, there is very little resistance. ”

Chen Mu carefully explained the operating principle of the train to Long Xueyao, and Long Xueyao admired it very much.

"Chen Mu, you are so smart!"

Chen Mu said with a smile: "But I, a smart person, also need your help, how to connect the wheels of this steam engine, you should have more ways than me." ”

Chen Mu's understanding of the train power system is mainly the wheels outside, which is very exquisite, but Chen Mu knows the correct appearance, and it is easy to restore.

But for how to connect the boiler, steam engine, and axle, you need to consult Long Xueyao.

Long Xueyao happily agreed, and then studied trains with Chen Mu, and they were inseparable in the College of Engineering.

Studying trains here, Chen Mu also proposed to build a railway at the same time.

Chen Xingtian listened to Chen Mu's proposal, but he was a little hesitant.

"Although the railway is good, isn't the gallop road repaired in vain?"

Chen Mu shook his head, "How can it be cultivated in vain?" It will be much more efficient to build a railway next to the gallop road. Moreover, the railway cannot meet all the transportation needs of Daxia, and it still needs to be galloped. ”

Chen Xingtian frowned and said, "However, it cost a lot of money to build the Chi Road before. Later, the cost of building guns, cannons, and vehicles was also very huge. ”

"The railroad requires a lot of iron and wood, which is more expensive than the gallop."

Chen Mu said with a smile: "It's okay, we can ask neighboring countries to pay for it to help us repair it." ”

Chen Xingtian was stunned for a moment, "This is not very good, although there are many subject countries around, but it can't be too bullying." ”

Chen Mu: "Where did you go?" Of course, it is not for their money for nothing. Whichever country pays for it, it can build the railway to their country. ”

"Transportation is convenient, trade volume has gone up, and everyone has money to make."

Chen Xingtian was stunned, "Is this okay?" ”

For Chen Xingtian, international trade is already unthinkable, and now it is unthinkable to build railways to neighboring countries.
