On the wall of Chang'an City, Ma Chao looked at the Li Jun camp about three miles outside the city in a daze, his expression was full of surprise and panic, "What is that?!" Could it be a new type of siege machine? How can it be that big? ”

"It's so high, it must be for the convenience of climbing the city! Your Majesty, the concubine thinks that you should immediately prepare fire oil and other things, and once that thing gets close, immediately attack it with fire! Otherwise, if you let the enemy easily climb the city wall, I'm afraid it will ......," Wang Yi said quickly.

"That's it! Weizhang! Righteous Mountain! I'll leave this to the two of you! Gather all the fire oil in the city! Zihua, you go and transport more stones and wood! When Ma Chao heard this, he immediately gave an order. And his eyes were still staring at the behemoth in Li Jun's camp.

As far as his eyes could see, pieces of wood or wooden materials were being assembled by countless soldiers. That is the building car developed by Li Yirang's Ministry of Industry.

"Finally able to see the power of this thing, will you capture Chang'an City in one go?" Looking at the behemoth in front of him, Li Yi's tone was full of expectation.

Although it has also been tested in Luoyang, the experiment is only an experiment after all, and no matter how simulated it is, it cannot compare to the real city battle. So up to now, Li Yi can only rely on the data obtained from the experiment to infer the power of the building car.

"This ...... Can this thing really push? Li Yi's side, Lu Bu and others showed the same shocked expression as Ma Chao, because the development of the building car was only known to Lu Wen and a few people except for the people from the Ministry of Industry. Not to mention Zuo Fengyi, Lu Bu and Gao Shun who were far away in Hongnong, and even many people in Luoyang didn't know very well.

"Yes, yes, but it's very slow," Li Yi said with some emotion......

"That'...... If the enemy kills out of the city......" When Lu Bu and the others heard this, they suddenly thought of a possibility.

In this era, there were no siege equipment similar to building cars, such as the well is one of them, which is higher than the city wall, which can easily allow the archers to condescendingly shoot at the soldiers in the city, and is one of the three major siege pieces alongside the ladder car and the rushing car.

It's just that a well can usually carry about ten soldiers, but today's building car ...... Or it should be said that this building car, the volume is obviously not comparable to the well. If the well is close to the enemy, it has no ability to counterattack independently, and it will not be able to run away at all.

"Yes, this thing can't run away from the enemy at all, and can only rely on friendly forces for protection. However, with its size, I am afraid it basically can't protect anything. Li Yi shrugged his shoulders and said lightly.

Hearing Li Yi's words, Lu Bu and the others didn't know what to say for a while. If you can't protect it, isn't that a live target? And it is also a live target that has been built with countless manpower, material and financial resources!

"Don't worry, you will wrap your outer body with mud and so on later, Ziliang has already tested it, ordinary fire arrows and fire oil can't easily burn it, and there will also be buckets and other things inside...... Li Yi explained with a smile. Then, he turned his head to look at everyone and smiled again, "As for if the enemy kills out of the city, this time I will test it first, and then I will let the Promise and Zigang lead the flying cavalry camp and trap the camp to protect it, but when you get to the city, you have to rely on others." ”

Hearing Li Yi's slightly playful tone, Lu Bu and the others really felt powerless, and the atmosphere of slaughter that was originally around them disappeared without a trace in an instant. But then, they suddenly reacted, "Lord...... Lord...... This building car ...... To the city? They asked, stammering, incredulous looks on their faces.

"Yes, I'll install something like a grappling hook at the top later......," Li Yi briefly explained the function of the building car. It's just that after listening to Li Yi's explanation, Lu Bu and the others were even more speechless.

The reason why the well is still able to become a siege weapon despite various shortcomings such as inconvenient movement and incompetence in close quarters is because the function of the well is only to carry archers to shoot at a long distance, and then cooperate with the siege troops, unless there are very strong troops in the city that can break through the siege infantry and kill the side of the well, otherwise the well is actually very safe.

Can this building car ...... It was actually used to climb the city? It may sound wonderful, but with such a bulky and huge siege machine, wouldn't the enemy be able to attack it with a single raise of his hand?

"Hehe, you don't have to be like this, whether it's good or not, just try it. Even if it fails, you can ask the people in the Ministry of Engineering to study why it failed. Keep trying, and there will always be a day when you succeed. After all, whether it is a catapult or other siege equipment, or even the various martial arts we have read and learned from the sages, isn't it also perfected little by little? Li Yi looked at everyone and chuckled.

Hearing this, the generals' expressions were solemn, and they said in unison, "What the lord said is very true, and his subordinates are taught!" ”

As Li Yi said, how much of a role can a siege equipment like a building car, which has never appeared before, play a role? He doesn't have much bottom in his own heart, but this does not prevent him from testing it through actual combat. Although there may be casualties, where can there be no casualties in war? Even in later times of peace, many experiments were actually done at the risk of their lives.

Well...... Well, in fact, the most critical reason is that Li Yi can bear the loss of the failure of the building car.

Under the watchful eye, the building car was finally built, after all, the huge volume of more than five zhang high and ten zhang long and wide made it difficult for others to ignore it.

Then, Li Yi waved his hand, and the attack officially began. Countless soldiers escorted this huge building car and slowly advanced towards Chang'an City, and after a short time, they came to the moat of Chang'an City.

"Ready to go into the water!" Lu Bu and the others watched this scene nervously, and they didn't seem to see the soldiers who were already pushing ladder trucks and other siege equipment across the pontoon bridge next to the building car, ready to start the siege.

However, this can't be blamed on Lu Bu, because in addition to them, there are many other people whose eyes are also focused on the body of this huge building. There were even some soldiers who were shot to death because they were distracted and did not take precautions.

With a "whoo~", the building car entered the moat. And after completely pushing it into the river, countless soldiers climbed into the building car, began to pick up the wood pulp on the side and began to paddle forward, and behind the building car, there were still countless soldiers helping to push. This is due to the fact that at the bottom of the cart, above the wheels, there are a large number of ship-like structures to help the cart float underwater.

When it was first designed, Ma Ming and Li Yi obviously took these issues into account, and not just how to cross the moat, but many other issues were considered. For example, the width of the moat varies from place to place, some of the moats are directly connected to the city wall, while others have a little land between the city wall and the moat. In this case, if the building car wants to play a role, it obviously needs some special devices.

As the distance got closer, Ma Chaoyue felt the kind of threat that the building car brought to him, because the building car was too tall...... It is almost level with the walls of Chang'an City.

"Wencai! You personally lead the men to defend the direction that the thing is coming from! In addition, Ziping, you take the archers to shoot it with fire arrows! What about Weizhang and Yishan? Send someone to urge them! Ma Chao kept giving orders.

Although he had never seen the building car, even if he didn't have Wang Yi's reminder just now, now that he saw him act like this, he could guess the role of the building car. And this is exactly what the defenders of the city are most afraid of. After all, if the besieging side can easily climb the city wall, the defender side will be very troublesome.

However, even without Ma Chao's order, many archers on the city wall who were adjacent to the building car now began to target this behemoth, but these arrows could not cause much damage to the building car at all, and they were all shot on the wood.

At the same time, dozens of soldiers who had already crossed the pontoon bridge were hiding under the carts, digging into the land adjacent to the river. In a short time, the slice was dug out of a slope.

"Push! Push hard! When the building truck docked, the soldiers behind it were pushing with all their strength, and there were people on the side to help cheer up. And under the city walls, dozens of soldiers also dragged the rope and kept pulling upwards.

By the way, at the bottom of the front of the building car, there is a slope arc similar to the bow of the ship, which Li Yi did not expect at first. Strictly speaking, though, many of the things that are part of today's building cars are the result of being added later.

Finally, the building car was dragged ashore and leaned towards the city wall little by little. The rain-like arrows on the city wall could not stop the approach of the building car at all. In a short time, only about ten steps away from the city wall, several huge wooden planks with grooves smashed on the city wall, revealing more than 100 soldiers hiding behind.

"Kill!" Seeing the city wall in front of them, these soldiers shouted excitedly, brandished their spears and rushed towards the enemy, and seeing this, Bao Chu hurriedly led the soldiers to meet them. At the same time, under the building car on the opposite bank, more than 100 soldiers were constantly climbing up the building car, ready to rush to support.

"My lord! It worked! Lu Wen shouted excitedly when she saw this. Although the soldiers in the building car have not been able to rush to the city wall today, they have clearly made a good start. And Lu Bu and the others on the side are also like this, and even many people are gearing up, as if they plan to take someone up to try it in person.

When attacking a city, the first to climb is often rewarded heavily, and the reason for this is because it is very difficult for the besieging party to climb the wall. To put it simply, although the ladder car can also rush to the city wall, because of the design of the ladder car, there are basically only two people who can step forward at the same time, and there is not much room to play, while the defenders can use various weapons to attack these two people at the same time.

But the building car solves this problem, and the width of about ten zhang makes it completely like a walled city. Even Lu Bu and the others can get the support of the soldiers at the same time when they have enough room to exert themselves.

"Let's take a look at the situation first, don't worry." Li Yi said in a deep voice, his expression was not as excited as Lu Bu and the others. Moody and invisible? That's not true, it's just that Li Yi still wants to see more, after all, this is just the beginning.

The war continued, and as the building car officially showed its power, the war began to enter a white-hot stage. Maybe it's because one of the Li soldiers in the building car can rush to the city wall from time to time? The morale of the Li army became more and more high, while the morale of the Taiping army, on the contrary, declined somewhat.

At this moment, Zhao Ang and Yang Fu rushed back with a large amount of fire oil and other materials. Seeing the current situation, there was no need for Ma Chao to say much, so they spontaneously led people to attack the building.

It's just that......

"Your Majesty, the enemy army should be wrapped in wet mud on the outside of the wood......" Looking at the fire oil and fire arrows that barely worked, Yang Fu said with an ugly face.

"Then burn people!" Ma Chao ordered without any hesitation. Although this thing was very unexpected, he quickly thought of some ways to deal with it, after all, this thing was just a platform to climb the wall.

After ......receiving Ma Chao's order, countless fire arrows and oil began to vent to the soldiers who tried to enter the city. In the face of the attacking fire arrows and fire oil, although the soldiers of Li Jun tried to resist with shields, but if they could block the fire arrows, how could they block the fire oil? Soon, the oil turned into a raging flame, spreading through the soldiers' bodies.

They shouted in panic and fled in all directions in a panic, suddenly throwing the original attacking formation into chaos. Seeing this, the tun commander who was in charge of leading the team hurriedly shouted for him to jump into the moat, and some even had to directly order him to be killed to prevent the fire from continuing to spread.

"Shoot!"

It was another round of fire arrows, and because of the chaos of the formation, many fire arrows shot directly into the building car.

"Throw!"

At the sound of an order, countless powerful soldiers threw the jars filled with fire oil into the building cart.

The top floor of the building car is also protected with wet mud, but the flame with oil is obviously not so easy to extinguish. Although the flames could not threaten the building car itself for a while, the soldiers could not resist the growing flames. They also tried to extinguish the fire, but they could not continue to attack, let alone fend off the countless arrows.

"Failed...... It seems that it is still too simple. Seeing the fire on the car, Li Yi shook his head helplessly and sighed.

"This ......" Lu Bu and the others looked at Li Yi, and then at the increasingly strong flames on the top floor of the building, and they didn't know what to say for a while.

"Mingjin." Seeing this, Li Yi said lightly, "If the building car is burned, the morale of our army will definitely plummet, and there is no need to continue fighting." ”

"The lord doesn't have to be discouraged, now he has seen the shortcomings of the building car, and he only needs to improve it, and it will definitely become a weapon for siege." Seeing this, Lu Wen hurriedly comforted.

"Hehe, that's nature." Li Yi chuckled when he heard this.
