Western.

Severus couldn't hold the city of Rome, so he had to retreat in the direction of Gaul with his troops, and entered the city of Masalia to garrison, and when he retreated, he also made gunpowder according to the technology deliberately sent by Yang Zhao, and also cast a simple cannon.

The Western army under the Taiping Dao was completely unaware that Severus also possessed firearms.

Zhang Ning was defenseless at all.

In the battle when Severus withdrew from Rome and entered Gaul, the Western army of Taiping Road was blown up by explosives and bombarded by simple artillery, and had to retreat.

Retreat all the way to the edge of Gaul.

Despite the possession of firearms, the entire eastern part of the Roman Empire became a occupied area and was occupied by the Taipingdao, but Severus was not worried at all and was still excited.

He saw hope in the firearms.

"Oriental stuff, it's really easy to use."

Severus said excitedly: "With those firearms, I finally defeated the Taiping Dao, we will fight back to Rome City, it is only a matter of time, you bring the gunpowder down, and study what kind of weapons can be made in addition to those explosives and artillery." ”

Gunpowder has long been brought to the West by the people of Taiping Dao, and it will be spread throughout the West in the future.

Yang Zhao has higher technology and is not worried about the impact of gunpowder in the West.

The people around Severus, after receiving the order, went to continue tossing the gunpowder.

"Next, we have to fight back against the enemy."

Severus was unwilling to say: "You guys come up with a plan for me as soon as possible, I will drive all the Taiping Dao out of Rome!" ”

Meanwhile.

Zhang Ning led his troops to retreat beyond Gaul.

Half a month ago, she led her troops to occupy the Apennine Peninsula, chased Severus, and came here all the way.

Originally, they wanted to kill Severus, but they would have thought that Severus also had firearms, and he set up an ambush on the way to retreat, blowing up nearly 80,000 of them.

"If I'm not mistaken, those gunpowder should have been sent in by Yang Zhao."

Sima Yi analyzed: "Yang Zhao has constantly arranged shadows to go deep into the West, and his people may come into contact with the Romans, so they will help the Romans resist us and delay our development." ”

Zhang Min said: "According to Zhongda, some of our things, in Yang Zhao's opinion, are no longer secrets? ”

Sima Yi nodded and said, "It should be like this." ”

There is such an enemy, and they feel a lot of pressure.

The Sima family wants to take revenge, but it is not easy.

"What Severu got was just the most ordinary firearms, and it was impossible for Yang Zhao to bring better technology to the West."

Zhang Ning said: "We just didn't have any defense, and we didn't think that Severus would have firearms, so we had this defeat, and then Severus couldn't stop my attack, and I could take the city of Masalia within half a month." ”

"The saint is right."

Sima Yi agreed: "It's not very difficult for us to take Masalia. ”

After a pause, he added: "It's just that it's not so easy to fight back the big Han, Yang Zhao's new weapons appear quickly and frequently." ”

Zhang Ning said confidently: "What Yang Zhao can have, we will have in the future." ”

The traverser inside their Taiping Road had already brought them too many surprises.

Sima Yi didn't know very well where Zhang Ning's confidence was, he was just looking forward to it, hoping that they could really fight back.

——

Yang Zhao returned to Luoyang and chatted with his family for a while, but before he knew it, it was already night.

"Why don't you light up tonight?"

He asked curiously when he saw that the sky was darkening and there was not even an oil lamp at home.

Xun Cai smiled: "Husband, we don't need oil lamps and candles now. ”

Yang Zhao asked curiously: "You don't need these, what kind of lighting is used at night?" When did you like this? ”

Listening to their husband's words, they smiled happily.

"My husband has been gone for too long, and I don't know how much we have changed."

Dong Bai came to the pillar next to him, there was something like a switch, she pulled it slightly, the top of the restaurant flickered, and the room was instantly covered with a pale yellow light.

Yang Zhao looked up and saw that it was a bulb similar to an incandescent lamp, and he noticed the existence of this thing.

Then I saw a wire coming in from the outside.

"In our house, there is electricity?"

Yang Zhao said in surprise.

Cai Jing nodded and said: "Ma Deheng said, this is electricity, as long as there is electricity, the thing called the light bulb will glow, and there will be no candles at home, electricity is made by the very tall dam outside the city, it looks amazing." ”

They didn't even know what electricity was.

When electricity was turned on in their homes, they were shocked at first.

Yang Zhao didn't expect that when he went out to fight, Ma Jun really made the power station and pulled the wires into the house, which was an unexpected surprise, and asked: "In addition to our family, who else can use electricity in the house?" ”

Zhen Jiang said: "The homes of many ministers in the DPRK and China can use electricity, and there is also the palace, but Ma Deheng said that ordinary people can't use it for the time being, and they don't have enough power storage technology." ”

At present, Ma Jun's electricity storage method only converts electrical energy into chemical energy.

This method, the loss of electricity is relatively large, and the efficiency of conversion is not high, so it can only be given priority to Yang Zhao and them to use, if you want to use e-commerce, you also need to continue to understand the knowledge brought by Yang Zhao to light up the technology tree, and continue to research and develop.

"That's pretty impressive."

Yang Zhao admired Ma Jun's ability very much, and asked: "Did Deheng say that in addition to electricity, what else did they make?" ”

Qiao Ying said: "There seems to be another thing, called iron or something." ”

Ma Yunlu echoed: "That thing is called a railroad track, which is used to walk the train, just east of Luoyang, we went out to see it once, a very long road, paved with iron, I don't know what kind of car can walk on it." ”

"Rails?"

Yang Zhao exclaimed.

Last year, Ma Jun came to Luoyang and only brought a semi-finished product of a steam engine.

Coming back from the war this year, they have already made the train?

The various data and technologies for making trains, which they researched so quickly, shocked Yang Zhao even more.

Ma Jun's ability is a bit against the sky!

"Husband, what is the railroad train?"

Elk Zhen asked incomprehensibly.

Yang Zhao said: "That is the kind of car that does not need to be pulled by horses, and it can travel day and night, and the speed is still very fast." For example, when we return to Donghai County from Luoyang, it may take a month for us to travel in a hurry, but by train, it will take a few days. ”

"So fast?"

Elk Zhen exclaimed.

Cai Yan said: "It must be very troublesome to manufacture such a fast thing, and the cost must be very high." ”

The cost is certainly not low.

With the current floating population of the Han Dynasty, there are not many people who can take the train, and it is not easy to build a railway and want to recoup the cost through the fare.

The current Han Dynasty needs to develop a sufficient population.
