The strength of the fortress lies in the cement, in the reinforced concrete, but also in its mechanical principles, the more perfect mechanical balance, and the hardness of the reinforced concrete structure, which constitutes an impregnable fortress, which is not something that can be shaken by the primary gunpowder of black powder.

The fortress has set up 2-3 floors underground, not for fun, it is a whole, completely brick and reinforced concrete, which eliminates the use of tunnels as a siege method, at most digging under the fortress, and it is impossible to enter the fortress at all.

Can't dig it out, anywhere in the fortress, it's at least 1 meter thick masonry and steel and concrete structure, this hard defense, in this era, is almost incomprehensible, especially underground, it can't be broken, gunpowder can't work, and manual work can't do it.

The power of gunpowder, that is related to the strength, the destruction of the city wall of Baozhou, because the power of gunpowder is greater, it is pushed by a hard object, and all the power is attacked in one place, and all the power is concentrated, and finally it is terrible to the extreme.

Just like a flashlight, a simple light bulb has a small brightness, but when it concentrates all the light, when it is projected into one place, it eventually forms a very bright light.

The strength of reinforced concrete is far above the ordinary city wall, almost three or five times more than the ordinary city wall, plus the structure and many aspects, at least 10 times more gunpowder, but also to seal well.

The coffin is not good, when the force acts towards the city wall, the wall blocks this force, and the power will bounce out, but it will attack the coffin itself and those layers of soil.

If you want to attack the reinforced concrete structure, you must use high-intensity explosives, the kind that can open the mountain and rubble, ordinary black powder, even if you use a lot of force, it is difficult to blast the rock, and even if you use that kind of high-spirited one, you need to make a lot of arrangements, when the force is concentrated to a certain extent, exceeding the huge strength that the fortress can bear, you can.

With Sun Ji's introduction, especially the bottom layout, and the example of the explosion, his own soldiers once went to the tunnel below after the explosion, and some of them were blown down, but the rest of the part, the temporary pile of brick walls still existed, and the huge explosion could not even destroy the brick walls that were close at hand, not to mention, the fortress, most of which were terrible fortifications with a thickness of two or three meters.

After knowing that the fortress would not be affected by the power of this gunpowder, Han Qi breathed a sigh of relief, the super weapon that was easy to fancy would not be stillborn before it appeared.

But after that, a greater sense of urgency also appeared, before, Han Qi was only from the military aspect, absolutely this fortress can be used, for military purposes only in the northwest, but now, seeing the results of Baozhou City, he has a sense of urgency, that is, for the safety of the Great Song Dynasty.

In case, the formula of this gunpowder falls into the hands of the enemy, and the Liao State and the Western Xia, under the premise of mastering such a powerful weapon, what kind of concept will it be, the powerful defense that the Northern Song Dynasty is proud of, in the destruction of this gunpowder, is almost like paper paste, coupled with the mobility of the Liao State and the Western Xia, the entire Central Plains are prostrate under their soldiers.

The Baozhou Mutiny is over, most of the people who know about the Wang family have died, and among the rebels, those who stayed behind are some who were wrapped up, or joined later, and they don't even know much about Miaojiazhuang, let alone know about the Wang family.

In fact, it is already a good thing to be able to conquer Baozhou, the casualties are very small, and the final time is a little longer, from the third year of Qingli to the fourth year of Qingli, after all, it is successful, clean up the rebels, count the losses, and do a good job of pacifying.

Han Qi didn't expect that in this Baozhou mutiny, how many deep-seated things there were, he didn't even investigate, before there were fewer family members, the whole Baozhou was in turmoil, and later there were more people who joined the rebels, there were local ruffians, and even bandits, etc., these numbers were already untestable, less than three or five thousand people, which almost everyone noticed.

Han Qi was filled with gunpowder, longbow and fortress, the three new weapons, especially the longbow, this weapon showed a different brilliance when it entered the forbidden army.

Elite archers are indeed elite archers, after taking Baozhou and handing over the affairs of civil affairs to Ouyang Xiu, Han Qi focused on the training of longbows.

These 30,000 troops did not belong to Han Qi, and before the imperial court finally determined that the Baozhou Mutiny was finally over, they were still under the command of Han Qi.

The power of the longbow in this battle is obvious to all, all those who have used the longbow are full of praise for the longbow, for the officer, the strength of the soldiers under his command is the strength of his troops, this good opportunity, how can you give up,

Miaojiazhuang also knows this, according to the number of 30,000 people out of 10,000 archers, in the next period of time, more than 6,000 longbows were made, basically, all archers, almost one each,

The elite archers themselves are very fast at mastering the longbow, and with the experience of others, the training of the longbow is also very smooth under the premise of going all out.

Zhao Xin also wanted to leave a strong army to the Northern Song Dynasty, and there was no hiding of private interests, the strength of the militia was not enough, the establishment time was relatively short, and there was no training in various professions, at most it was attacking, so that a group of peasants who didn't know anything could learn archery and routines in a short period of time, which was already very good, and if you wanted to complete more training, it would not work at all.

Zhao Xin has been preparing for the defense of the city since he obtained the fortress, and he has not prepared for field battles, but the training of the forbidden army, all kinds of shooting skills, have long been MAX, at most from short bow to long bow, these are difficult things for ordinary militia groups, and it is not very difficult for these elite marksmen.

After the initial training, after mastering some basic means of the longbow, they were no longer interested in these low-level skills, and it just so happened that Sun Ji was taught by Zhao Xin and began to teach some real English longbow techniques.

Individual skills, small-scale cooperation, large-scale cooperation, cooperation for armies alone, jungle operations, plain operations, as a mature combat system, the English longbow can exist in a separate formation, many situations take into account, he is not closer than cavalry or infantry, there is no way, or even can only hold his head to run around, he has a complete set of combat methods.

There are so many such methods, even elite archers can't master them in a short time, but some officers, even at the level of sharpshooters, see the essence from the middle.

Ordinary longbowmen, there is no way to fight alone, he must have cover, or a certain defensive force, longbows in this regard, also need, but not so urgent, there are some cavalry and spearmen, press the flanks, help them support the attack distance, this is the best, if not, longbowmen also have a unique method of combat, with a method similar to kites, with other troops.

The secret of this is in the training, different routines, different methods of coping, these army commanders and envoys, and then realized the power of the longbow, before they only felt that this could be a weapon to replace the short bow, and after that, more and more found that this thing simply changed the military system of the Great Song Dynasty.

With a longbow, many types of troops can be collected, not to mention the short bow, the advantage of the longbow for the crushing of the short bow, and even the blocking archer, can also be replaced by a longbow, at most, is to increase the strength of the bow, with a stronger bow, instead of a softer longbow.

If it is said that the only use of the short bow is probably used by the cavalry, but the cavalry of the Northern Song Dynasty is the most lacking.

In addition to the short bow, heavy infantry, light infantry, and some other types of troops can be reduced as appropriate, and when the number and proportion of archers are greatly increased, the attack power of the whole unit increases, but the survivability does not decrease much.

Attack is the best defense, but in the vast majority of cold weapon warfare, it is not reflected, the reason is very simple, defense is easy to pile up, this is an objective law, under the premise of the same attack power and equipment level, defense is always easier than attack, it is the same for siege, and the same is true for field warfare.

However, the longbowmen, with sharp attacks, faster steel delivery speeds, and displayed attacks, the same number of cavalry, even if they are heavy cavalry, are difficult to break through in the face of longbowmen with armor-piercing bows, not to mention other troops, it may take three or four times as many people to rush over.

This is just a comparison of the data, in fact, the war, far from being as simple as the data, the reason is very simple, why is it said that in the era of cold weapons, a team, the loss of 3 percent, has collapsed, on the one hand, these 30 percent, is definitely the elite force of this army, less 30 percent of the elite, the strength of this army, will be greatly reduced.

On the other hand, in feudal society, in the era of cold weapons, medical capacity and logistical supplies are not up to par, and once the casualties are too large, the psychological pressure is enough to crush everyone.

It's not that there are no battles to the last soldier, but these battles basically have no way to retreat, why the siege is missing one, is because to dispel their idea of stubborn resistance, in the face of a large number of casualties, facing the premise of death, they will almost certainly retreat.

That is to say, the previous short bow did not reach this limit, and the current longbow, on the premise of strengthening the attack power, has exceeded this limit, as long as it is not a fully armored cavalry or infantry, even under the premise of a single longbow, it is impossible to enter the attack camp with less than half of the loss under the premise that the longbow man does not react.

Not to mention, a small number of heavy infantry and cavalry, no more, each can achieve one achievement, such an army is incomprehensible.
