The huge team of 300 people, including many senior officials such as the governor and the cabinet secretary, can be said unceremoniously, almost all over the fields of the Northern Song Dynasty, almost the Northern Song Dynasty came out, the largest scale, and all aspects are also the most complete group, the most important thing is that he only has senior officials, and no ordinary staff.

In order to determine the closeness between the navy and the Northern Song Dynasty, especially the Northern Song Dynasty secretly laid a telegraph line, unlike other things, as long as the telegraph has a small office, after the telegraph line, it can be connected with the distant Shenyang, and the news of the high-ranking official groups of the Northern Song Dynasty was reported to the Ding Navy at the first time.

At that time, there was a certain disagreement about letting Han Qi go back, but some preparations were made, mainly the various influences that Han Qi could have, but no one thought that such a huge delegation would be ushered in, which almost represented the essence of the Northern Song Dynasty.

When the news was reported to Zhao Xin, Zhao Xin was very calm, and the huge power could always have a very terrible effect, and now, the Dinghai was stronger than the Northern Song Dynasty, but it was not a little bit, not to mention the financial strength, just the population, the territory, these in the feudal society, the most basic, but also enough to crush.

Why, Mongolia could easily take the Northern Song Dynasty, especially in the early days, Mongolia was even frustrated, the defense line of the Northern Song Dynasty gave Mongolia great casualties, and even Meng Ge died under the siege battle.

But in the later period, why did Mongolia get stronger and stronger, Mongolia has the world's largest territory, population, and various advantages, for example, the return cannon to conquer the city of the Northern Song Dynasty was obtained from Central Asia, if there is no return artillery, perhaps, the Southern Song Dynasty will still be broken, but in terms of time, it will definitely be delayed a lot.

The Dinghai Navy is far stronger than Mongolia, whether it is the army or the territory, the most important thing is that the Dinghai Navy controls things that Mongolia cannot control, thermal weapons and various technological products.

Compared with the Liao State in the past, the only advantage of the Northern Song Dynasty was the financial revenue, the various scientific and technological levels, as long as it developed slowly, it was possible to overtake, but when it met the Dinghai, it was not only an all-round crush, but also a lot of crushing, under such a premise, as long as you figured it out, anyone could make a choice.

This time, Zhao Xin gave the main tone, that is, deterrence, a comprehensive display, the military strength of the entire Ding Navy, on the contrary, the economy and construction capabilities, can be placed on the other side, the basic data, Han Qi already knows, to a certain extent, this is a naked show of muscles.

The whole expedition lasted for a total of one month, and the entire expedition group was very tightly arranged, and they almost traveled through most of the military projects of the navy, from the army, to the navy, and even the air force that had just entered the military sequence.

Speaking of this air force, because of Zhao Xin's vigorous investment, including filling a large number of technical personnel in the aircraft research institute, under reasonable guidance and almost unlimited investment, fruitful results have been produced.

The horsepower of the aircraft engine has increased rapidly from 25 to 120, and at the same time, the development of twin engines is basically in place, the emergence of aluminum alloy, as well as various coatings, itself, the strength of the wing, are far more than that of ordinary wooden aircraft.

Power is the core of an aircraft, and a more powerful engine can bring strong power to the aircraft, and the performance in all aspects will also rise.

At present, the performance of the aircraft has reached a flight speed of up to 250 kilometers per hour, and the take-off weight of the aircraft has also increased greatly, and after a certain reinforcement of the cabin, it can carry about 800 kilograms.

800 kilograms, in later generations, may be the weight of an aerial bomb, large aerial bombs, 1000 kilograms, 1500 kilograms, is not enough, but for this era, it is enough.

The Dinghai Navy even opened up an arsenal to conduct research on aerial bombs, and aerial bombs, compared with artillery shells, are very similar, and some of the early aerial bombs are simply replaced by mortar shells.

Touch leads, as well as timing leads, both of which are very important for the bomb, are installed on the bomb to ensure the effect of the bomb.

At present, of course, there are no protective targets, and the targets of aerial bombs are also lethal, mostly 5 to 20 kilograms, unlike artillery shells, because aerial bombs can be thrown from the sky, they do not have to take into account the shape of the aerodynamic force, at most they take into account the amount of charge and lethality.

Zhao Xin proposed the practice of steel balls, which has also been applied, with the addition of a large number of steel balls and the input of many high explosives, to a certain extent, the power of this aerial bomb is greater.

Surface ships, armored cruisers are powerful, they represent the largest artificiality that the entire human race can make, and it can move.

However, the Northern Song Dynasty was a traditional land country, and it was not very cold about sea power and sea power, but things like airplanes were exceptions.

Flying in the sky, the minimum is generally more than 500 meters, this distance, for the current Northern Song Dynasty, is unattainable, even before, a strange person like Sun Ji, he can open a 10-stone strong bow, and can also shoot at least 1000 meters away from the enemy, but if he shoots an arrow in the sky, the maximum range is only a little more than 300 meters, almost two-thirds less.

At the same time, even if there are some arrows, barely past 500 meters, at high altitude, he is definitely the end of the crossbow, and there is no lethality at all.

This point can not only be applied to archery, but also to some air defense weapons in later generations, the ultimate range of six or seven kilometers of artillery, if the anti-aircraft modification, its effective range, will be greatly reduced, to maintain sufficient attack, even on the basis of the maximum range, but also to add an effective range.

At present, although the aircraft has such and such shortcomings, there is no problem with the exercise, and in a relatively dense area, a large number of dummies and targets are installed, as well as some living animals, cattle, sheep and pigs.

A total of 3 planes carried out the mission together, projecting 2.4 tons of aerial bombs, 5 kilograms of aerial bombs, the charge is at least 2 kilograms, and there are at least 1500 steel balls in it, once they explode in the air, these steel balls will become a killing weapon, crazy shooting, maybe most of them can not hit the effect of bullets, but in terms of coverage and lethality, it is terrible.

The previous cruiser's naval guns, one shot down, almost cleared an area, at that time to the Northern Song delegation was very impressed, but later, in the face of the flying things in the sky, they were even more unable to talk about it, they could only be beaten passively without resisting, and the killing efficiency was also very terrible.

The three planes almost completely plowed the surrounding area and the area that could be seen by the line of sight, and everywhere they went, not to mention that there was not a single grass, most of them were killed and injured.

This taught the officials of the Northern Song Dynasty a hard lesson, human beings have the desire to fly to the sky since they recognized the birds, but from ancient times to today, that is, in myths and legends, there are animal beasts about Luban, and some people even think that he is suspicious of the village, and it is more likely to be a kite.

But now, the plane is such a thing that can't see what it is, it can fly smoothly into the air, and it can attack, it is very terrifying, just like the body of a bird, equipped with a bow and arrow, it is absolute suppression, only passive defense.

The plane is more powerful than that, one by one like a hen laying eggs, but it is dying, the army of the Northern Song Dynasty, if it is under the premise of a field battle, it is difficult to resist, even if it is a defensive battle, these will have a huge lethality to the Northern Song Dynasty.

In the face of the plane, the only thing that those military generals can think of is the problem of running fast, running fast, and being able to quickly get out of those bomb-covered areas.

However, the technical officials of the Ding Navy directly blocked their idea, the speed of the aircraft, at present, the aircraft of the Ding Navy, has reached 250 kilometers, and in the future, when the new generation of aircraft engines is developed, it may reach a speed of 350, or even 400 per hour.

Speaking of a speed of 250 kilometers, maybe the officials of the Northern Song Dynasty did not have an intuitive understanding, but it was twice as fast as the fastest speed of the train, and these officials understood it in an instant.

Train, is currently the fastest means of transportation in the Northern Song Dynasty, it can be said that it has brought great changes to the Northern Song Dynasty, originally, maybe a month or two, or even more journeys, now, can be changed into a thoroughfare, shortened to 10 times, or even 20 times the extent, thousands of miles of trekking, is not a difficulty, as long as there is a railway, it may take a day, it can be reached.

But this plane, his speed, is even twice as fast as the train, let alone the galloping horse, the speed of the train is 3 times that of the galloping horse, this already knows, under the speed of the plane, 6 times the speed of the galloping horse, even if it runs, how far can it run.

However, the most shocking thing and the last straw that broke the camel's back was an air show after the aircraft exercise, this time, the Dinghai Navy took out all the planes, and anyway, at an altitude of one or two thousand meters, it could not be seen.

When the dense airplanes appeared in the air, everyone was stunned, and after seeing the strength of the airplanes, many officials in the Northern Song Dynasty pinned the concept of survival on the small number of airplanes.

That's right, he is still very weak compared to the navy, the army, and the newly established air force, but this weakness, you see who it compares to.

After determining the model of the aircraft, the navy only needs to use a small number of factories and build a small number of factories, and then build a few factories, it will be able to show the effect, which is vividly displayed in the aircraft, in just three months, the navy has built 120 aircraft, and at the same time, the agricultural aircraft built in the past, even for transportation, for sowing and pesticide use, have also been taken out.

It doesn't matter if it's wood, it's metal, it doesn't matter how fast it is, the last time it's showed, it's flying slowly, and everybody's speed will be slowed down, so quantity becomes the key.

At least 800 planes were densely packed and flew slowly in the sky, and the planes were connected together, almost covering the sky, including the most powerful and radical officials and generals of the Northern Song Dynasty, all of whom did not speak, and in such a situation, even with 200,000 or 300,000 troops, how could they bomb them.

The appearance of the plane completely announced the collapse of the armed forces, and the plane and the train cannon, also showed the ability to siege the city, the 500 kg of aerial bombs on the plane, fell at an altitude of more than 2,000 meters, the impact force generated, almost devastated, if added high explosives, the power is stronger.

Not to mention the fortresses of the Northern Song Dynasty, even if it is a high-standard fortification made of completely reinforced concrete structure, it can be easily destroyed.

Field warfare is impossible, not to mention aircraft and artillery, even if it is an ordinary army with a navy, under 10 times the number, the Northern Song Dynasty does not dare to win, plus train artillery and aircraft, it is the icing on the cake, and there is no chance of victory in field warfare.

As for the defense of the city, it is even more not, artillery, train guns, airplanes, all have lethality to fixed defenses, how can people fight.

An exercise to show muscles, just like that, in the silence of the Northern Song Dynasty officials, the dust settled, and the muscles of the Navy were displayed very well, and the Northern Song Dynasty officials, who may have been tendentious, have already made a choice, and those who have not begun to consider this matter.

When this group of high-ranking officials of the Northern Song Dynasty returned to the Northern Song Dynasty, after at least half a month of quarrels, they finally ended under the clap of Renzong, first stabilized the Northern Song Dynasty, and he took the initiative to propose to the Ding Navy and wanted to visit the Ding Navy.

This visit, in fact, every year, Zhao Xin will invite, the invitation to Renzong is only incidental, the main purpose is the concubine, the concubine has a stable status in the Northern Song Dynasty Palace, and Renzong is also very good to her, but the children are in the navy, he must be lonely.

Of course, it is impossible for Zhao Xin to go to the Dinghai Navy, as far as security is concerned, the officials of the entire Dinghai Navy will definitely not be allowed to bring troops to go, then it is not a visit, it is a war, and it is Princess Fukang, she has no problem, she has an identity in both countries, and she will go to see the concubine every year.

Now, Renzong agreed to this invitation, not the concubine went, but Renzong took the concubine and went together, which not only made Zhao Xin very happy, but also caused a shock in the Northern Song Dynasty.

The low-level officials didn't know what to do, and they wrote to block it, but surprisingly, most of the high-ranking officials, who participated in political affairs, didn't say much, in the past half a month, similar quarrels and arguments have appeared countless times, everyone knows the result, either go to war or surrender, and no matter which one, Renzong can only make a decision alone, even if this decision is shocking, but he still has to do it.

Renzong's visit represents a certain attitude, and Dingjun is already clear, but Renzong's identity, whether as Zhao Xin's father or the emperor of the Northern Song Dynasty, is the same, Dinghaijun has been well prepared, and this is the official invitation, probably in March of the 21st year of Qingli, Renzong traveled.
