In this era, the Northern Song Dynasty was the best at attacking cities, not only had excellent siege equipment, but also had a perfect siege system, but most of the attackers would use bows and arrows to cover the way, use the time difference, put the ladder up, and then send the outstanding body, risking the danger to climb the city, as long as people go to the city, it is possible to expand the advantage, more and more people climb up.

In this case, on the city wall, pushing to the ladder, you need to brave the rain of bullets, as well as the possible attacks around, and even the risk of being shot into a hedgehog, but here, just hide in the room, you can't attack inside, you can't hit the inside outside, and even 10 civilians with good strength can do all this, even if you can't push it, holding a spear and stabbing indiscriminately, it can also have an effect.

Correspondingly, there is no way to attack these people in the siege, on the one hand, these air holes are quite small, and long-range weapons such as bows and arrows are difficult to shoot even in the hands of a terrible archer like Sun Ji, let alone hit the people inside through the two or three meters long city wall.

This is naturally invincible, as for the ladder, it is even more impossible, on the ladder, it is impossible to carry a long weapon, the thickness of this thousands of heights, at least two meters, only a special wooden fork, can poke out, attack the ladder.

The rivers and lakes have a little trick, and if they are broken, it is simple, Zhao Xin broke it like this, and suddenly made Sun Ji understand the horror of these holes, which was simply easy, but the defense was extraordinary.

It's such a simple arrangement, why didn't the entire military of the Northern Song Dynasty think of it before?

Imagination is one aspect, the military of the Northern Song Dynasty is relatively solid, and does not use much new military technology, but more reason, it is still to focus on building materials.

In the previous building mode, the slightly wider city wall, there are some problems, too high and too big, easy to collapse, in this case, barely build a tall city wall, it is already good, how dare to dig holes in the city wall, these holes, may become the weak link of the entire city wall, used by the other party, perhaps with a sassal impact, or with other methods.

Cement and bricks, this is not the same, it is completely different, he can build very high, can be as strong as stone, in the stone, make a hole, and understand it in the brick wall, it is completely different, the strength will not be greatly reduced, this is also the original intention of this method.

Only the combination of cement and bricks, more than 40 meters, is not the limit of cement and bricks, in this case, there is a margin to build such a unique design.

No wonder Zhao Xin is not worried at all, the other party uses a ladder, this is a ladder that is very high compared to an ordinary ladder, and its weight is very large, so it is not easy to be pushed, but under the bottom of the kettle, it is more likely to suffer losses.

This kind of ladder can help the besieging army quickly cross the distance of dozens of meters between them and climb to the top of the city.

But they didn't expect that compared to ordinary ladders, at least 30 meters high, how many soldiers would be on it, according to each 3 meters apart, that is, more than a dozen, so that the city head, pushing them became heavy, you know, almost a thousand catties of strength, to be able to push this ladder.

But from the middle, or even the bottom, you don't have to push them away completely, as long as you let them balance it, they can be destroyed in the end.

You know, this is at a height of 40 meters, six or seven meters high, falling down, injured a lot, but after more than 20 meters, it can really fall to death, if below, in the potholes, uneven, even more so, it's just a Jedi, the person who fell, maybe just fell, fell to death.

After Sun Ji finished reading it, he stopped talking, to be honest, he didn't expect that this fortress would actually be arranged with so many killing machines, it can be said that the seemingly ordinary outer wall is all pits, even if you don't need to retreat, it is terrible enough to cut off the ladder with a saw blade or something, let alone retreat.

At this moment, Wei Gui and they didn't realize that they would encounter a kind of attack, they were still making engineering equipment, mainly for napping, the bow of the longbow had limited ability, and the face and foot armor could not shoot through, and the nap with iron and cowhide was almost 4 inches thick, enough to resist the attack of the longbow, and the thickness was to a certain extent, and it was also a kind of protective ability, and the production of the ladder was the most, since, to confirm that the opponent's defensive ability was limited, at least, it was overstretched, then, From four aspects, saturated attacks are the best way to take down this city defense, just like they did before,

Almost more than 300 meters in circumference, and eventually 70 ladders will be prepared, but when they made the ladder, they found that it was really difficult to make it so high, and the ladder made according to the previous experience was too fragile, and it was easy to assume that when the ladder was made, the ladder itself could not bear it, and after several failures, the final ladder was much heavier than before.

On the battlefield, there is a calm, everyone knows that this is the last calm before the storm, once the calm is broken, the next thing is a stormy attack.

Whether he can resist this attack, Sun Ji is not worried at all, but how strong the defense strength of this fortress is, it needs to be tested.

Compared to the calm outside, the inside of the fortress is not calm at all, before, it was just a possibility, let more than 10,000 people, concentrated in this small place, but now, the rebels are really coming, the number of troops, far more than their total number, this kind of substantial threat, the pressure brought by it, is really unbearable.

caused a series of fluctuations, people's hearts are the most difficult thing to grasp, especially the hearts of the Jedi, if it weren't for the prestige of Miaojiazhuang in the past, as well as Zhao Xin's reputation, maybe he would have collapsed.

Fortunately, the team drills easily blocked the first wave of attacks, and when the team drills who participated in the war told their relatives and friends about the war, and spread it in the fortress, it was considered to stabilize the situation, otherwise, just internally, it was enough to make them anxious.

This also gave Sun Ji a certain feeling, the fortress is a professional military fortress, can not involve civilian, placed in the north, can be used in some other cities, instead of the role, but the simple fortress itself, or the military role.

This point, it doesn't matter in the northwest, the northwest is vast and sparsely populated, and it is not suitable for forcibly marching soldiers and civilians, but it is a simple military fortress, which is easier to arrange, not only the defense is strong, 1,000 people and 10,000 people, and the logistics supplies required are also completely different orders of magnitude.

A few days passed slowly, Wei Gui didn't even provoke, he couldn't be calm, but in the outside world, he wasn't calm at all.

The news of the Baozhou mutiny still spread, after all, the mutiny of a prefecture and a city of 100,000 people, even if it is deliberately controlled by Wei Gui, even if it is the potential influence of the Wang family, it is impossible to cut it off, this is a major event that shakes the entire north, not to mention, since the Wang family has instigated all this, on the bright side, it must do everything possible to clear up the relationship.

But when the news spread one by one, the whole north shook, this is Baozhou, the northern military state that is very close to the border of the Liao-Song Dynasty, and at the same time, it is also painstakingly managed by Renzong, and there is a mutiny here, which is simply an earth-shattering event.

In itself, it should be the first time to mobilize troops and go to the border pass to quell the rebellion, but the first thing to consider is the conspiracy of the Liao State.

That's right, between the Liao and Song Dynasties, although there has been no war for a long time, the battle between the two sides has not stopped, and on the secret front, I don't know how many swords and swords, and the two sides have millions of soldiers, and they are really not put out to see, once the two sides have any weaknesses and are grasped, the other side will drive straight in.

As far as the conspiracy is concerned, the first thing to guard is the border, and secondly, the mutiny in Baozhou.

Baozhou, at best, is a second-rate military state in the border area, at best a few thousand troops, and in northern China, which is full of heavy troops, these thousands of troops can't do anything big, as long as there are no loopholes in the border.

On the other hand, it was divided into several roads, and the news of the Baozhou mutiny, quickly passed through the canal and the Yi Road, and frantically marched to Beijing, and finally after the Baozhou mutiny, it was sent to the Privy Council, and then the entire Northern Song Dynasty political arena was shocked.

This is probably the most serious mutiny after the establishment of the Northern Song Dynasty, the forbidden army of a state capital was all in turmoil, and there was no news or movement before.

The time of the early dynasty is approaching, and almost all the high-level leaders have got the news about the mutiny, and everyone knows that above this early dynasty, the focus is on this mutiny, and they all need to adjust the movement and adapt to the situation.

In the deep palace, Renzong was sitting at the head of the bed, in the early hours of this morning, the secret channel was directly transmitted into the palace, and the news of the Baozhou mutiny was presented to him.

Sending Zhao Xin out of the palace is a last resort, even if he is the emperor, he can't do whatever he wants, let alone the court like a sieve, his safety can be guaranteed, and others, he can't put Zhao Xin under his nose.

Tigers have times when they take a nap, not to mention the emperor who is always in charge, and he doesn't know how to take care of a child of intellectual age.

Baozhou, who thought he was safe, was used by the other party to flip the table, he was familiar with the intelligence system of the Great Song Dynasty, and he knew very well that it had been two or three days after the mutiny, and the other party was scheming, and even the mutiny had come out.

A trace of tears of remorse dripped from his eyes, only in a person's time, he would show such a weak state, but soon, Renzong adjusted his mentality, his hands were clenched, his muscles were violent, anger filled his heart, and there was a voice outside the window urging inside, and the time had come.
