The two of them sat on the boat for about half an hour, and the swamp air boat suddenly stopped again. Qing Cang thought to himself, what happened again? And looking ahead, there seemed to be no more dams or other things, but the swamp air boat did stop.

Zhou Cang expressed his doubts about the sudden stop of the swamp air ship. He must have thought about what happened. At the same time, he expected that the more danger it would be greater. After all, behind it was Cao Cao's territory, and it was very normal for him to control heavy troops in his territory.

It was already a fact that the air boat stopped. Since this was the case, he changed the air boat's automatic driving mode to manual driving mode and drove down the Yellow River. After driving for less than five minutes, he saw a turning point. He quickly looked from a distance and seemed to have a new city appeared in front of them. After Qing Cang stopped the boat, he immediately picked up his telescope to watch. On the city tower in the distance, there were two words written in Tongguan.

Tongguan is located in the north of Tongguan County, Weinan City, Shaanxi Province, facing the Yellow River to the north and the mountainside in the south. "Shui Jingzhu" records: "The river flows south from the gate to Tongjiguan Mountain, so it is called Tongguan." It was built in the first year of Jian'an in the Eastern Han Dynasty (196). It was built last year, so all this is new.

Tongguan is the eastern gate of Guanzhong. It has always been a battleground for military strategists. It ranks second in the top ten famous passes in China. It is known as the "first pass". Emperor Qianlong traveled through the great rivers and mountains of the empire. When he walked here, he couldn't help but feel the steepness of Tongguan and left a gilded imperial book on the "first pass" on the banner outside the city tower.

Tongguan was occupied by Zhao Zilong some time ago. Now Zhao Zilong has returned, and Tongguan has returned to its original state. It has begun to inspect passing ships. This kind of inspection is very strict, and the strange shape of the air ship cannot be passed.

As for the reason why the embankment was already exposed, they must be afraid that there would be troops like Zhao Zilong to reach Tongguan through there. So they set up a dam as an obstacle and set up a large number of officers and soldiers downstream. If an army wants to reach Sishui Pass through water or a further place, they must pass through the dam, otherwise they will not be able to reach their destination. This is why the Cao army built an dam.

At the same time, why do we have to arrange so many troops on Tongguan? This is the reason for him.

Zhou Cang saw Qing Cang stopping the ship. At the same time, he also saw the place of Tongguan. He asked, "Commander, what should we do next?"

What to do? This is what Qing Cang thought.

There seem to be only two roads to walk at the moment. First, find a pier nearby to get ashore, and arrive at Guandu by land. However, the speed will be much slower by land. Second, force pass through. Qing Cang took out the map to watch. This place called Tongguan is located at a corner of the Yellow River and is in the shape of L. He is just a little above the turning point of L. At the same time, the shortest place at the intersection of the Yellow River here is only 170 meters.

If the Cao army set up a pass here to block 170 meters. They then concentrate their troops to 170 meters to defend. Then for Qing Cang, the difficulty will rise sharply. However, if you do not pass the level and walk on land, the arrival time of the two will be greatly affected. After all, the speed of the ship is still higher than the walking speed and the speed of riding a horse. The endurance of the horse is limited, so people will be tired.

Qing Cang immediately made a decision and faced Zhou Chang's question. He said, "Zhou Cang! Hold the handrail! We are ready to break through."

Zhou Cang was shocked when he heard this.

"What? Commander, don't you think about it carefully? This is not a dam. They don't know how many officers and soldiers are stationed here. And their weapons should be quite advanced. Just like our muskets. If they hit the air ship, that's not a good thing for us."

It has to be said that what Zhou Cang mentioned still has some reference value, but in a comprehensive assessment, they seem to have no other choice except for forcing the pass. Besides, Qing Cang also has numbers in his eyes. As long as the numbers in his eyes do not change, do not decrease. Then he may safely pass through the mouth of Tongguan.

So he said, "It's okay. Believe me."

Zhou Cang had no reason not to believe it, as things had come to this point. He had accepted Qing Cang's choice.

So he said, "Commander! I'm ready. His hands are tightly holding the handrail." This time it can't be like last time.

Qing Cang shouted, "Are you ready?"

Zhou Cang should have done so, so Qing Cang pressed down the accelerator. As soon as the accelerator was pressed, the engine roared. Just wait for him to put down the clutch, the ship could fly out. At this time, there was still more than 200 meters away from the guards of Cao's officers and soldiers.

The huge sound of the engine made the Cao army directly discover their place, so someone shouted: "Oh no, if there is an enemy, please quickly notify the soldiers guarding the city to come and support."

With this order, someone immediately took action. A large number of soldiers gathered on the edge of the Yellow River. People were everywhere on both sides of the Yellow River. They not only held muskets, but also set up cannons. At this moment, Zhou Cang was so scared that he was trembling all over. Such an attack was much more powerful than a dike. If he was hit by a large number of cannons, he would either die or be injured. The people here were too terrifying, and three or four hundred cannons were parked on both sides of the Yellow River.

Perhaps it was Zhao Zilong's appearance that made them feel very stressed. It can be said that if Zhao Zilong came again, he might not be able to escape the pass. The scene was too terrible.

"The commander is not good, they have a cannon."

Zhou Cang shouted in a hurry.

Qing Cang just smiled and had a playful expression. He said, "It's okay! You held the handrail tightly."

As soon as he finished speaking, he directly released the clutch. The swamp air ship flew out quickly. A large number of splashes burst out from behind the ship, which was very beautiful. However, Cao's army, who guarded the Yellow River left and right, did not have the heart to watch these splashes.

Facing this uninvited guest, they picked up the guy, turned the gun head, aimed the muzzle and gun at the place of the air swamp ship. They heard the strange sound of the air ship coming to the engine, which made them afraid. They had never heard this sound, nor had they seen this unique air ship. In their opinion, the ship must be made of wood. However, the air ship of this shape was painted with a lot of strange colors, and it was not made of wood.

Someone shouted: "The army obeys the order and fires."

With this order, three or four hundred cannons were bombarded at the same time. A large number of shells hit the air ship, and the shells fell on the water surface, causing bursts of water. But I don’t know what to do, their cannons could not attack the air ship.

You know, the movement speed of the air ship alone cannot escape the attack of cannons. However, the strange air ship can avoid the bombardment of cannons in time at critical moments, which made them puzzled. If they knew, it was caused by the numbers in Qing Cang's eyes.

If the value in front of Qing Cang decreases sharply, it will turn left or right. It can react several seconds or milliseconds in advance, so the scene just now appears. This is why Qing Cang dares to break through, because he has a powerful tool, and there is a number similar to a plug-in. It can be said that with this number, he can be undefeated.

The air ship was still shuttled on the Yellow River and was constantly approaching the pass. Speaking of this pass, Cao's army gathered a large number of people and used a large number of ships. They were connected together, leaving only a small mouth in the middle. All those who had been inspected must pass through the small mouth until the inspection was passed before they were released. With such a small hole, it is difficult for the swamp air ship to pass through such a small hole. However, with Qing Cang here, everything would not be possible. Faced with this pass, the air ship was getting closer and faster. It was so fast that people's eyes could not keep up with its existence.

But Cao's army would not sit and wait for death. Someone here ordered: "Listen to everyone! Take out the musket, reload the shells, and aim the cannon at the ship. You must not let the ship leave here, otherwise you will be killed without mercy."

It has to be said that this order has played a certain role. Everyone put away their contempt. They thought they could kill the strange ship soon, but now it seems impossible. Because it is too fast, so fast that they can't find the target of attack, and it rushes left and right, with no rules at all.

But there are still people in Cao's army who understand. He is a general-level figure. He shouted: "The ship will inevitably pass through the pass. As long as we block that passage, the ship will definitely not be able to pass. All ships are connected together at a speed!"

After ordering, the soldiers downstream moved immediately, and they would pass the ship across the small pass through ropes. Qing Cang would definitely pass through this path, closing it little by little.

They are trying hard to close them, and Qing Cang takes all this in his eyes. If they are closed, it will be very unfavorable for the breakthrough.

He wanted to speed up, but it was slower because the pass not far ahead had been completely closed, a large number of ships were crossing it, and there were a large number of cannons on the ship, aiming at them. Once he dared to fly over and before he could rush over, he would inevitably be smashed to pieces.

Zhou Cang saw all this, but in fact he didn't know what to do. But he wanted to know what to do with Qing Cang, so he asked him again: "Commander, what should we do next?" During the entire mission, Zhou Cang only played a bodyguard role. Qing Cang could only do the decision. He didn't know so much, but he was unwilling to be told the result, so he wanted to participate.

Qing Cang said, hold on, you'll know in a while! Qing Cang still didn't tell him what he was going to do, because there was no time to say it now.

"Hmph. Don't try to keep me."

In Qing Cang's eyes, these ships wanted to trap him. Is it very huge? Because it has an ultra-modern swamp air ship.

Qing Cang looked at the places on both sides of the pass, and there was most of the mud. So he thought about it and shouted quickly.

"You're going to pull it off on Wednesday! We're leaving."

After saying this, I immediately pulled the accelerator and the huge engine sounded again. The huge fan blew the wind backwards, and a large amount of water splashed, clattering. A large number of water splashed behind the frost of the empty ship, and the scene was very spectacular.

At this time, there was still one or two hundred meters away from the pass. He drove a swamp air boat and rushed towards the pass.

At this time, the soldiers on the mouth were dazed because the speed was too fast. The one who ordered just now came to react first.

He shouted, "Pull the cannon barrel at the ship, don't let him run away!"

So all the cannons were aimed at Qing Cang's ship. When they approached one hundred meters, the man suddenly shouted and fired the cannon. They immediately lit the fuse. The fuse club was burning quickly.

boom

The shell flew out in a direction where Qing Cang was.

Qing Cang then saw their cannons clearly. It turned out that the caliber was also small-caliber, so they could shoot them at a short distance. He thought to himself, it must be the small-caliber cannons made by Chen Shou, who had sent back the message, the Heilong and the others?

There are weapons in Huaxia City, and Black Dragon. The two sides have steam engines. If the steam engine is also invented by them, once they build steam engines, their power will be even greater. After all, they have people from the Three Kingdoms. The people from these Three Kingdoms have gone to Huaxia City several times as many times.

If they were asked to build trains, the railway would be very easy to be paved. If the railway was released, then the Three Kingdoms would connect and form a railway network, which would not be good news for Huaxia City.

Therefore, the purpose of this trip became very important. He must destroy their steam engines and not let them build the steam train, which would be fatal to them. If he had the chance to encounter a black dragon on this trip, he would definitely kill the black dragon to avoid future troubles. However, there were nine of them. He also asked Yang Xiaomei to check the locations of these people, but there was still no such thing.

Their anti-reconnaissance ability is very strong. Qing Cang remembered that when he found the black dragon, he still spent a lot of effort to find out where they were. With his reconnaissance ability, it was very difficult to find them. Moreover, with the intelligence departments of the Chinese Legion, because those intelligence departments were also taught by him.

All this depends on luck. If you are lucky, then the black dragon will die. If you are lucky, then you can only wait for the black dragon and the others to come. He believes that with his grudges with him and the black dragon, the black dragon will definitely come to Huaxia City again to inquire.

Let me talk about one thing here. That is the internal combustion engine. Some people may think that when the internal combustion engine is invented, will the Black Dragon steal their achievements? But what I want to say here is that the times are gradual. If they cannot enter the steam era, then they will enter the electrical era at once. Is it difficult to do anything to go to the sky? The instruments and components required for the internal combustion engine are more refined, and it is very difficult to mass production.

Once you have a steam engine, you can continue to improve through the industrial assembly line and successfully enter the invention of the internal combustion engine, and continuously produce the internal combustion engine on the assembly line, and apply it to war. This is why Qing Cang was very anxious after the steam engine was stolen.

Judging from the value of the steam engine alone, it is indeed much worse than the internal combustion engine. But from a long-term perspective, if the Black Dragon also enters the steam era, then it will not be long before he defeats Qing Cang.

Having said that, Qing Cang asked Zhou Cang to help him. Zhou Cang was already scared and shivered at this time. A large number of cannons had been released, and the target was them. At this moment, Qing Cang suddenly turned a corner. Just one hundred meters away, he turned the air ship to a 30-degree angle in time. His target was not to break through the pass now, nor was it the center of the pass. After the shells flew out soon, they failed to hit the swamp air ship, so this time Qing Cang escaped again.

Just when Cao's army was puzzled, Qing Cang was already rushing towards their edge. There was a lot of mud there. After closer inspection, there was a raised triangle.

Zhou Cang will only know what to do next. Because the air boat can walk on the swamp in the morning, the triangle area in front of him is equivalent to the swamp, so his boat will not sink into the mud, on the contrary, it will walk quite quickly.

Cao Jun shouted, "Look, that guy is going there."

The general of Cao's army was distracted: "It's just a matter of death. If the boat is gone, how can she walk? Everyone will follow me and keep me in the mud for a while. They will definitely be trapped in it. It's time to clean up them!"

But when the general finished speaking, the air ship flew over in front of him, yes, it flew over. It existed on the mud and did not appear to be sagging, but instead walked very fast.

The air ship finally broke through the gate of Tongguan. This scared them very much and shouted: "What the hell is this? Why is it so magical?"

After a while, the swamp air boat had disappeared from their sight. They realized that they wanted to notify the people downstream.

The general said, "I'm sure you can't let her pass through Hangu Pass. I think they must go to Guandu. Those two are from the Chinese Army."

At this time, Tongguan quickly ignited wolf smoke. This kind of wolf smoke can be seen clearly within a radius of dozens of miles, and it has specific signals, so Hangu Pass basically knew that someone had rushed to Tongguan, and they also started to get busy and must stop the passers-by.
