From the day he was attacked by Cao's army, the entire Huaxia City was ready for war. Under Qing Cang's leadership, everyone continued to study science and technology and develop industry. Among them, the invention of armored vehicles brought them great confidence. However, the battery life of armored vehicles was very poor and needed a lot of coal to assist. Its mobility was not enough to cope with the ever-changing war.

Therefore, Qing Cangming's subordinates kept striving for excellence and made every effort to invent the internal combustion engine. At this time, the industrial level also reached the primary level, which was completely sufficient to produce the internal combustion engine.

From zero to existence, it took nearly ten years to complete the entire Huaxia City. Even if it started from scratch, nothing could stump Qing Cang's Chinese Legion. It already has knowledge far surpassed that of that era. The advanced concepts brought by Qing Cang have brought a qualitative leap to the entire Huaxia Legion.

And Qing Cang exchanged a book called "Modern Oil Exploration Points" from the system. Through it, we can roughly determine the location of oil, especially the location of the Southern Huns.

In this way, the book brought great convenience to their exploration. Yes. If there is oil, gasoline and diesel can be extracted from oil. Modern petroleum products will be more common, and everything that modern can do. In this era, he can also do it completely. With oil, internal combustion vehicles will begin to develop, and they will also develop internal combustion engines without stopping.

He had reason to believe that the black dragon must also develop in this regard. Because in ancient times, wars were mostly through horsepower or artificial movement. If it was only based on horsepower and artificial movement, then the difficulty of mobilizing the entire army was very huge. To achieve a quick battle and decisive decision, it had to develop transportation. The Chinese Legion did better than him. As long as Qing Cang developed a little, it would definitely bring a new change to the entire Huaxia City.

But how could the Black Dragon let him develop? He would definitely make trouble from it. Just like today, intelligence personnel have come up to report. "Commander, some of our train routes to the Southern Xiongnu were destroyed by Cao's army."

"What! Destruction! These guys are really annoying!"

For now, this kind of damage is very fatal. Because once it is destroyed, the transportation of coal will become extremely difficult. If the coal becomes less, the energy will be less, and the energy that survives there will be cut off by the black dragon.

He also has to spend a lot of effort to rebuild the railway, and the money, material resources and manpower are also huge.

At the same time, another news that shocked him even more came into her ears. That was the report from the intelligence officer.

"A huge steam train was lost on a railway near the Southern Xiongnu. Moreover, only the front of the car was lost."

Qing Cang suddenly felt that this matter was extraordinary. It must be that Heilong took Cao Jun and stole his steam train locomotive. You should know that the weight of a steam train locomotive weighs dozens of tons or hundreds of tons, and it is not very easy to pull it away.

"What! Lottery the locomotive! These guys! Who did it!"

"It is understood that it is Cao's army!"

Ten people in the Black Dragon assisted the Three Kingdoms respectively, and the Black Dragon brought four people to Cao's camp, among which Chen Shou was killed by him, and three others. The matter of Cao's army stealing the locomotive must have been done by Heilong.

"Black Dragon, can't you sit still?"

This surprised Qing Cang very much. They actually took action first. The Black Dragon is really here this time.

Guo Jia asked, "What do they want to do?"

Just a steamed car head, what can they do?

Xun Yu also said: "Yes, are they also short of trains?"

"No, they want to use our steam engine to study!"

Qing Cang's words made the two of them realize that research is right, just study.

Guo Jia said:

"Research? Does that mean they want to use weapons of war, too?"

"Yes, I think they want to build a chariot like us. These people are really unwilling to give up. There are nine people in them, and each of them is a cruel person. If they don't kill them, I'm afraid my Huaxia City will be in peace in the future."

Although Heilong and others were able to make muskets, it was because they had two weapons experts. Weapon experts did not mean that they could make steam engines, so they did this. They wanted to popularize steam cars by studying Qingcang's train steam engine. If they succeeded, the consequence would be that they would also be on the same level as Huaxia City, both in industry and in military terms.

Qing Cang really has no way to do them. The train tracks are fixed on the ground and can drive off the track like cars. At this time, the importance of internal combustion engines is revealed. The invention of internal combustion engines is imminent.

The news just now was not the most terrifying. What was terrifying was that another intelligence officer came up to report: "Report to the commander, we, Yu Lishi, found the traces of Cao's army. They used a carriage to pull something, please instruct."

Guo Jia said: "Lishi? What are they doing when they are near the Yellow River?"

Xun Yu guessed: "I think they want to take the steam engine downstream through the Yellow River ferry."

Guo Jia said again: "Well! It is possible that they want to pass through the Yellow River and take the steam engine along the Yellow River to Sishui Pass, which is the closest city to Xuchang."

Xuchang was the capital of the Han emperor and Cao Cao's old nest. To put it this way, it must be the Black Dragon instructed these Cao troops to do this.

After hearing this, Qing Cang felt it was very reasonable and said, "In this way, they will intercept their ships and not let them take our steam engine to Xuchang. That will be a fatal injury for us."

Guo Jia said: "Yes, Commander, I think it's only if you ask Chief Zhao to lead troops to intercept them immediately."

At this time, they must be intercepted and the steamed car head cannot be allowed to fall into their hands, otherwise they will develop to support the train, so for them, this consequence is unbearable. They must not be allowed to develop. Otherwise, the battle will be quite difficult to fight.

He recommended Zhao Zilong because of his trust in him, and probably only Zhao Zilong has this ability.

Xun Yu added: "Captain Zhang can also go with him!"

Zhang Liao's strength cannot be underestimated. These two men have gained the trust of the two major staff members, so they strongly recommend that they fight.

Qing Cang agreed, and he said, "You two have very good opinions. Come and ask Commander Zhao and Commander Zhang to come and see me."

"yes!"

Then the guards informed the two commanders of the army and asked them to come here.

Zhao Zilong and Zhang Liao quickly arrived at the meeting hall, and they said, "Commander!"

"Captain Zhao, you bring 30,000 knights, take the muskets and board the train to Jinyang, and flow down the Yellow River to intercept a group of Cao's army. They stole our things. Don't let them take the steamed car head away. Commander Zhao, your 30,000 troops can only reach Tongguan at most. If you can't chase Cao's army before that, you must return!

And Commander Zhang, you also brought 30,000 knights to Hangu Pass directly. If you don’t meet Cao’s army after you arrive, you will return. Remember, you must not fight with Cao’s army!”

Zhao Zilong asked, "Commander, why is this?"

Qing Cang said: "Our railway was attacked by Cao's army, and our locomotive was stolen by them, so I want you to help intercept the locomotive and not let the locomotive arrive in Xuchang. But if they have arrived, you must return, because their strength is no longer the strength they used to be. There are still a few terrible people in Xuchang!"

The people Qing Cang refers to were Heilong and others.

Guo Jia added: "We are stolen by them. We are going to stop them from stealing the fruits of our labor and prevent them from studying our locomotives. Do you understand so?"

After hearing this, the two of them said straight: "Yes, yes, we know, let's do it now."

Before the two of them left, Qing Cang stopped them.

"etc"

The two turned around, wondering what he was going to do.

"You bring the lamp source with you. In this way, you can still travel overnight. In this way, you can quickly reach your destination. Because this matter is extraordinary, you must not let the steamed car head fall into the hands of the black dragon, otherwise the consequences will be unimaginable."

If you really fall into their base, it is equivalent to making wedding clothes for others. Giving up the six years of hard work to others. They robbers don’t care about you. As long as they have the skills, they will snatch them and become their own.

Qing Cang was still thinking about a question. That is how did the Black Dragon know that he owned a steam train? And the location he chose was extremely accurate. The place he chose was the Southern Xiongnu, which was far away from Huaxia City.

And they wanted to transport the machine through the Yellow River, all of this was planned. It was not on a whim, and it might have been arranged long ago. Fortunately, they had not gone far, and it might be possible to intercept them, but Qing Cang also made plans. If there was no way to intercept them, he could only let it go. Anyway, he would also accelerate the development of internal combustion engines and focus on the development of new guns. This time, he must protect bullets and other secrets as secrets, and must not let the Black Dragon send people to infiltrate them.

Two major advisers:

"I saw that the time was ripe. It would be better for us to go south and catch Cao's army off guard."

"Yes. Rather than developing, it's better to take the initiative to attack."

Qing Cang had his own considerations, and he said, "The whole world is extremely wide. If you move rashly, you may not be able to eradicate the roots. I believe that it won't take long to attack my Huaxia City again. Because his group of hatred has reached the level of insolvency. I am waiting for him in Huaxia City. This time, he must make sure to go back and forth!"

His thinking is not without basis. Now the black dragon is in the dark and he is in the light. It is difficult to catch the nine people. If they do not rely on the Three Kingdoms, then there are more choices. This is a world, not only the Eastern Han Dynasty exists, but also the three empires of Eurasia, which is really a giant existence. If they are allowed to penetrate the three empires, it will be difficult to fight to the sky. It is equivalent to killing all the three empires.

Since he wanted to fight, he had to kill them all, and he could not leave any possibility. So he chose to develop weapons, wait for 10% of the weapons to induce Heilong and others to come and attack the city. At that time, they would be defeated in one place. As long as they died, the Three Kingdoms would be directly unified by him. At that time, his mission would be completed.

Sometimes he is thinking about a question, whether to stay or go back. Since he owned this system, he has tasted the sweetness of power, and he has tried to ask about the system, but the system has not responded to this question. Or from his observation, unifying the Three Kingdoms is just one step, and the real difficulty is that it is not important to take the whole world in this way. Even if he goes back, it will be a change of things and people. It is better to dominate the world here, think about what he wants, and be the king of the world. Everything about women, treasures, territory, etc. will belong to him. This is his real pursuit.

Guo Jia echoed:

"If this is the case, it seems very reasonable. To be external, you must first do your internal strength. If you have strong internal strength, what will the enemy fight against us?"

Xun Yu also said: "The commander is right. We are really too eager for success. It is a question whether they can survive when everything is well."

"As long as you two assist me and manage the entire Huaxia City, my Huaxia City will be indestructible."

There are many things that the two major staff officers have to do, from internal affairs to diplomacy. Facts have proved that with the existence of the two, Huaxia City has indeed become better. This is better than Qing Cang's management, and Qing Cang doesn't have much time to manage the entire city. After all, the scale of this city is moving towards five million people.

The two of them dare not be greedy for merit. "The commander and leader are good at all!"

"Hahaha!"

Qing Cang suddenly remembered something and asked, "Staff General Guo, how old are you now?"

“Twenty-six!”

Qing Cang said: "Well, you should be getting married long ago at this age."

He has mentioned this more than once. It would be a waste if Guo Jia, who has such a high IQ, does not leave a son or half of his children. Of course, he also thought about Guo Jia. In ancient times, it was too late to get married at this age.

"Commander... I will devote my life to Huaxia City. The marriage can be done slowly."

"Slow down? No, no, I think it's faster. Which one do you like in the Women's Army? Just mention it directly. If you don't say it's far away, just Bai Yu. He has already formed a bond with Leng Wanjun, but you literati and poets are not in a hurry."

Two years ago, he had already tried the policy of intermarriage among soldiers. Basically, generals had found a suitable wife. Guo Jia made him very anxious and talked to him several times, but he never succeeded.

Xun Yu got married early and came out to persuade him: "Yes, the commander is right, you should find a companion."

"This... I really didn't think about it."

Guo Jia's circle is small, so he didn't know many people, so Qing Cang was worried about him.

"It's so big!"

Qing Cangyu said earnestly.

"Commander, don't talk anymore. I have something to do, so I'll take my leave first!"

Guo Jia left in a hurry, which made Qing Cang and the others laugh. However, he also took Guo Jia's affairs to heart. As for Qing Cang, he had not found a woman who could touch him, he had been committed to development over the years, and he really thought less about that.
