Liu Tai's tactics are actually a step-tan synergy tactic from the twentieth century.

Relying on the protective power brought by the steel of the multi-purpose boxcar, it supports a space on the battlefield that is large enough for the Han army to move.

At this time, the heavy armor soldiers began to follow the chariot to clear the various defenses built by Zhao Guo on the battlefield.

They held heavy shields in their hands and steel armor on their bodies to resist damage, and they basically destroyed the defenses on the periphery of Tongguan.

After all, don't look at this kind of tactic as simple as it seems, but even in the meat grinder war of the 21st century's Da Mao Ermao Civil War, this simple and crude tactic is still used, at most, the equipment is more advanced.

And now Liu Tai is facing Zhao Guo, although this tactic is a simple beggar version, but this is a tactic of the twentieth century, and it is a tyrant tactic brought about by the scale and quality of his steel industry after surpassing Zhao Guo.

Of course, this is also a matter of course, think about how much money Liu Tai has spent on materials science, especially into a god old Ge Hong, who is almost the top chemist of this era.

If Ge Hong found all the characteristics of charcoal and iron, he would inevitably ignore these basic elements, especially transparent glass, an artifact exclusive to research, which had not yet been burned out by those guys who burned glass, and Ge Hong's progress would naturally be slow.

However, in the process of studying carbon and iron, Ge Hong naturally made many by-products like a lottery, especially high-strength steel, and made several kinds of them.

For ordinary researchers, they are the consumables on the road of the big guys, and their lifelong research is to prove that a certain material that they have worked hard to study is completely meaningless, which is a wrong route.

But for this kind of big guy who has luck and alchemy talent, as long as he is willing to do it, relying on his own one percent of inspiration, he can often make new material alloys as blessed.

And because Liu Tai attaches great importance to experimental records and procedures, especially Ge Hong's experiments need to be recorded.

After all, this is something researched by the big guy Ge Hong, the research product of a top chemist who has been out for hundreds of years or even thousands of years, even if the by-product is afraid that it will take a lifetime for a general consumable researcher.

In this process, whether Ge Hong found out all the basic properties of coal and iron, Liu Tai did not know.

However, with the help of the by-product steel alloy made by Ge Hong, not only the strength, hardness, and toughness have completely transformed from iron to steel, and it is so strong that it completely forms a generation difference!

In this way, Liu Tai's defense system to clean up Tongguan can be described as overwhelming, completing the destruction of various defense facilities in front of Tongguan at an incredible speed, ensuring the formation of a large open space not far in front of Tongguan, so that the siege weapon of the thunderbolt can be smoothly placed.

At this time, Liu Tai began to arrange for the army to start building camps and organizing defenses, instead of directly attacking Tongguan in one go, he chose to fight steadily and steadily, and the siege weapons and equipment in the rear should also be transported over and built first.

His own troops are clearing up obstacles on the battlefield, and they can still be on top with this beggar version of the coordinated combat method.

But the siege of the city, especially the dangerous level of the attack on Tongguan, requires siege weapons, not this kind of infantry and tan coordination tactics.

In particular, the shameless defender of the city, after seeing that the weather was cold, poured water on Tongguan every day, and made the surface of Tongguan smooth with the help of low temperature, especially in winter, this ice cube became stronger and stronger, and I am afraid that the defense of Tongguan will become stronger and stronger in the future.

Because of this, You Ziyuan didn't understand why Liu Tai would attack in winter, after all, no one had heard the story of the Ice City in one night, but here in Tongguan, it had not been more than a hundred years when Cao Cao beat Ma Chao to operate this move!

Therefore, You Ziyuan rushed to Tongguan with his troops, although the speed at which Liu Tai cleaned up the peripheral defense facilities was so fast that You Ziyuan felt incredible, but at least this tall and sturdy Tongguan brought You Ziyuan a little warmth.

At this time, there is only such a strong male pass, which will not live up to his expectations, which makes You Ziyuan relax a little.

It's just that soon Youziyuan couldn't laugh anymore, because by the time the camp was built, the engineering equipment was assembled, and the thunderbolt under Liu Tai's command began to wield, and when the throws were thrown at the city wall, Youziyuan had already found a good place to hide.

However, although the wanderer Ziyuan had a little doubt at this moment, he was not panicked.

After all, the thunderbolt is not a strange thing, at most it is the difficulty of this craftsman's skill, but how many years has this thing been out, with his own operation of Tongguan, the stones on the catapult can smash the ice on the city wall, but if you want to smash the city wall together, it is too underestimated to strengthen Tongguan.

"Soldiers, don't be afraid, find a good cover, raise the shield on the side, and try to guide the direction of the falling stone if there is a stone falling!"

You Ziyuan also knew that if he really smashed it down, he wanted to resist it in this way, and it would depend on whether his fate was good or not.

But I can't say it, and then everyone will resign themselves to fate and see if this stone will hit themselves.

In an instant, falling rocks rained down, and these stones were thrown towards the city wall, and those soldiers standing on the city wall, if they were really hit, they would naturally die, and they might not even want a whole corpse.

But as these implementations fell on the city wall, we saw that the wall continued to shake, and it was inevitable that it would be damaged in early summer.

"I always feel that the opponent's siege weapons are so strong!" At this time, it was said that Youziyuan's face couldn't help but be ugly.

Liu Tai didn't pay much attention to it, because the first wave of Liu Tai's army was just a simple test shot.

As soon as the first wave of test firing was completed, Liu Tai immediately asked the thunderbolt to adjust the throwing angle and throw it around the gate.

In contrast, when building a barracks, the tent gate is often the strongest place to defend it, but this is not the case when attacking a city.

Especially in cities such as Xiongguan and Dacheng, their walls are often strengthened and strengthened with rammed earth for many years, and it is too difficult to directly collapse the city walls with a thunderbolt.

However, the city gates are generally made of solid wood, which is much more convenient for the attacker.

Of course, even after breaking the first gate, there is often an urn city inside, and you still need to continue to attack the mansion.

But even if it is an urn city, it is much more convenient than if you need to feint on your own, after all, under normal circumstances, the effect of the urn city is only used once, and if you can occupy the commanding heights steadily, it is not easy to give full play to the effect of the urn city.

At this moment, You Ziyuan looked at Liu Tai's thunderbolt cars directly lined up, throwing stones continuously, and couldn't help gritting his teeth.

This stone-throwing rain lasted for almost half an hour, even the wanderer couldn't help but be a little puzzled, Liu Tai took so many stone-throwings, don't you need money when these stone-throwing!?

And under this rain of stones, basically the defenses on the city wall were simply swept away, and even the city gate of Tongguan itself was in tatters.

However, Zhao Guo obviously did not cut corners on this city gate, at this moment the decoration on it was smashed by stones a lot, and the gate looked tattered, in the end this gate was not collapsed.

"Start the siege!" Liu Tai saw that today's stone throwing was almost over, so he began to give orders to the soldiers and officially attack the city.

It is said to be a siege, but more precisely, it is not the kind of direct climb of the city wall for a full-scale siege.

Instead, an engineering team was formed with siege weapons such as well fences, rushing cars, and boxcars to carry out key attacks on the city gates.

At this moment, on the top floor of the well railing, there are Changshui soldiers who carry out as much archery rain as possible, and shoot covering the city wall.

On the second floor of the well fence, there are soldiers with the sound of shooting, and the operator has a strong crossbow in his hand, carefully peeking at the battlefield.

For the shooters, they operate strong crossbows, and the target is those centurions or tun commanders on the battlefield who show a command posture, and accurately block them, or play the role of point shooting.

Obviously, You Ziyuan didn't expect that Liu Tai's attack on the first day would be such an all-round suppression.

Generally speaking, Liu Tai's offensive rhythm is abnormal.

Normally, when the army comes under the city wall, it needs to be delayed for a month or two, after all, it is necessary to build a camp, it is necessary to build siege weapons, and it is necessary to boost morale.

All in all, this kind of sneak attack with a ladder or a barb is normal, but this kind of direct siege weapon attack, you Ziyuan has really never seen it, and he is naturally not well prepared to deal with it at this moment.

After all, in Youziyuan's original thoughts, the outer defense facilities of Tongguan held back Liu Tai's march.

At the same time, Liu Tai also needed to rest on the spot, collect timber from a distance to build siege weapons, and use this time to carry all kinds of garrison materials to the city wall, and the two sides had a dignified battle between spears and shields.

But Youzi was far from expecting that Liu Tai's speed of cleaning up the peripheral defense facilities he had arranged far exceeded his expectations.

At least by the time I came, these had been cleaned up.

The tactics of the chariot with thick armor, after the wanderer heard it from his own men, there was only an indescribable incredibleness.

Because I never thought that there would be such a local tyrant's tactics.

And before he even had time to reflect, he needed to face Liu Tai's attack like a tide, focusing on the thunderbolt throwing of the Dian clan at the beginning, and now being suppressed by Liu Tai in all directions, not giving himself a chance to breathe at all.

This city gate, which has been smashed by catapults, can no longer support it in the face of the continuous impact of the rushing car, and the entire gate directly collapses.

The city gate of Tongguan, under Liu Tai's all-round attack, collapsed without even holding out for a day!

As the gate was opened, the soldiers in front naturally continued to charge forward, for this, even if Liu Tai knew that this was only the gate of the urn city, it was easy for the soldiers to close the door and beat the dog after entering, but Liu Tai did not stop it.

Because in some places, even if there is a clear card pit, it also needs soldiers to step on it with their lives, and love soldiers like sons, and use soldiers like mud.

Only by letting the other party use the Broken Dragon Stone can he completely relax his mind in the next attack.

And for veterans, they naturally know that as the first to arrive, this is a risk they need to take.

However, the soldiers with siege weapons such as rushing cars remained at the gates of the city, preparing for the Broken Dragon Stone that might appear at any time.

At the same time, two Xu boxcars drove directly to the gate of this gate, blocking both sides of the city gate with their own cars.

Liu Tai was very calm, and when he saw that the city gate was breached, he immediately ordered the soldiers to start pushing the ladders, double-headed flying ladders, hitchhikers, etc., which were specially used for climbing the city wall, and began to climb Tongguan, in order to completely take the outer urn city first.

And You Ziyuan saw that Liu Tai did not rush into Tongguan because of the risk, but chose to completely seize the urn city steadily, knowing that he could not wait for Liu Tai's main force to enter the urn city.

If it was any later, it would have been terrible if the city had really been captured by Liu Tai's army.

So at this time, You Ziyuan directly ordered to put down the broken dragon stone, but saw a loud bang at the gate of the urn city, and the huge broken dragon stone fell down, although the two Xu boxcars resisted slightly, but they also inevitably made a creaking sound, at a speed visible to the naked eye, the iron sheet and stone wood outside, and the filled stone inside could not resist this broken dragon stone.

Liu Tai's pupils shrank when he saw this scene, although he had expected it a long time ago, but seeing his soldiers sacrifice because of his own decision, he was absolutely uncomfortable in his heart.

"What about the ladder, what about the double-headed flying ladder, and what about the sky car! Climb to the city of the urn for me, and take the warriors home! Liu Tai said loudly.

Liu Tai knew very well that his order was just to make up for the loss, but at this moment, an ironclad soldier wearing iron armor on the front line put down the weapon in his hand, stretched out his hands, and half-squatted as a support to carry the broken dragon stone.

They are all Liu Tai's thousands of selected wrestlers, although one person is naturally not like Confucius's father who directly carries the thousand-pound city gate alone, but one two, three wrestlers...... A small team of wrestlers worked together to finally stop the fall of the city gate!

"Let's go! Let's go! The wrestlers shouted: "The king has an order, take you home!" ”

Those soldiers who rushed into the urn city, and the soldiers who were already desperate did not hesitate, but they were also ready to retreat.

At this time, a military historian stood up and said loudly, "You retreat in an orderly manner, and I will write straight and write about your heroic posture today!" ”

Hearing this, the veterans, who had been in some turmoil, quickly came back to their senses.

While maintaining the military formation, the soldiers retreated in an orderly manner, and the rockets prepared by Youziyuan in advance did not have time to play a role.

A group of people finally fought while retreating, exiting this desperate situation, and at this moment the military history turned back happily and said:

"Ladies and gentlemen, today's merits, I will definitely write straight to show your merits!"

However, at this time, the military history saw that the blood that kept gushing out of the mouths of these wrestlers had stained their armor red.

Even if they create miracles in military history, in the end they are just mortal wombs!

However, as they watched their comrades-in-arms evacuate smoothly at this moment, the corners of their mouths also showed a somewhat relieved smile.

"The army of tigers, with one enemy of five!" This wrestler finally let out a shout, and this broken dragon stone could no longer support it.

These people were directly read as meat puree, and they were crushed into two pieces like those boxcars!

Blood splashed on the face of the military history, and the only thing he could do was to truthfully record today's events, in order to prove that Zeng Lili sacrificed to save his comrades!
