According to Xiao Xuan's previous understanding, through many costly means such as inner iron, medium copper, and outer bread steel, the body tube of about twenty-five kilograms finally had the momentum pendulum estimated to be about 40,000 joules when firing, and it could launch a heavy bullet of about 400 grams at the limit speed of black powder about one and a half times the speed of semisonic speed. Among them, the core of about 300 grams, like a short arrow-like "armor-piercing body", reached a power of about 30,000 joules. The brick wall or earthen rampart with a thickness of about one meter almost a hundred steps away seemed to be unable to withstand the power of the eight taels of steel arrows, and it was completely penetrated, and then the wooden targets wearing iron armor seemed to have suffered a lot of trauma. It is obviously a weapon fired by a single soldier, but the actual penetration and power seem to be the projectiles of some medium and heavy army artillery, and it is difficult to compare with it in some aspects.

"With a range of about 200 paces, at least one time can penetrate the ascent of five heavily armored and heavy shield officers and soldiers or ten human targets, which is undoubtedly the combat effectiveness of a heavy artillery. Such a cannon can now be operated and aimed with precision and dexterity on the shoulders of a soldier. The two gunners worked together to reload and fire, and in almost two minutes they could fire at least seven rounds of ammunition from a single loaded ammunition, taking into account the tension of the battlefield and possible training errors. It is easy for two people to kill and wound thirty or forty people in a short period of time on the battlefield, so that two hundred artillery groups can kill and injure seven or eight thousand people in a short period of time, and even if it is an army of tens of thousands of troops, there is no certainty that it can do so. Moreover, if some officers and men on the battlefield are obviously brave, they can also adopt the method of filling the ground with the majority of the people and the firing of a small number of people in a concentrated manner. In this way, the whole tactical system will be greatly innovated... ”

A middle-aged craftsman who had spent at least seven or eight years on this project seemed to be a little excited. Many of the people who participated in this project were not too old, because only those who were not too old and had a certain level of skill and physical strength were able to have enough awareness to accept the long-term training under the new system, and finally put into practical use some things that were impossible to put into practical use and manufacture.

Xiao Xuan also did not expect that some ideas for simulating smoothbore armor-piercing shells in later generations would be successful in this plane. Of course, today's machining capabilities are not enough to meet the machining accuracy of metal projectile smoothbore guns, and it is easy to have the life problem caused by deformation.

Of course, Xiao Xuan also knew that the opponent on the battlefield might not necessarily be able to attack in a dense formation according to the expected requirements, and this kind of armor-piercing projectile seemed to be slightly upgraded to the times compared to history, and it could not adapt to all situations. So, there is also an arrow shotgun shell weighing about eight hundred grams. It is about 800 grams of cartridges, and when the shells fly out, about 100 small arrows about 5 grams will fly, and each arrow has a weight of about 5 grams. Although it is very light, it still has the ability to threaten armored targets at a distance of about 100 paces, and the threat ability is higher than that of traditional shotguns. According to the firepower test and deduction, the comprehensive combat effectiveness and effectiveness have also begun to have the ability to enable firearms units to kill and injure opponents more than 10 times their own strength in a very short period of time, and to confront dozens or hundreds of times the opponents.

In this way, even if you don't let the people around you specially select strong elite soldiers and smell the chickens dancing every day, you can start to be able to use a battalion of battle groups or so to fight against a strong enemy with a size of at least tens of thousands.

Of course, the effect of this is not first of all reflected in foreign wars, but also in the internal deterrence of this era. When the monarch has the resources of violence, which can be controlled at a low cost and risk, and can be effectively separated from the economic base provided by certain social classes, he has power that is truly unshakable.

It was also at this time that the reorganization of the new guard battalion began. Considering that "flowing water is not corrupt", the term of office of the troops around Xiao Xuan also began to be limited, and he still appointed officers and soldiers who began to serve at the age of thirteen or fourteen and served at the age of twenty or seven years. After retirement, these people become a group with certain interests and special treatment, but in general, because these people are selected without a specific source of interest groups, the monarch's influence and control over them is much easier. Especially when the strength of the entire team comes more from sophisticated firearms and equipment, rather than its own martial arts.

In addition to sophisticated firearms, with a lot of new talents and minerals acquired since the expedition, the technology of making plate armor has also begun to become much more sophisticated. In the case of the use of the finest plate armor, only a dozen kilograms are needed to reach the load, so that the entire soldier can be armed with hands, faces, and also has considerable protective ability, and the whole team is not equipped with too many carriages and only relies on a small number of pack horses to have strong combat effectiveness.

These technological changes have begun to reduce the political risks of "micro-service private interview" tours, which did not seem too reliable in the past.

Therefore, when the New Guards Battalion was established, Xiao Xuan also felt an unprecedented burst of excitement, and said to the team that was also excited and seemed to have some energetic young recruits: "Now that the enemy on the surface of the country seems to have been defeated, there are not many of the strongest opponents overseas. Many people may feel that they are born ten or several years late, and have not caught up with the era when military merit is easiest to attain, but I want to say that many things are not too late, and the responsibility on your shoulders is not lower than that of the elite volunteers who made great contributions back then. Because the strength of a country lies not only in its external military merits, but also in its internal transformation. However, there are many people in this world who are still obsessed with the habitual authority and interests of the past, and they are very uncomfortable with the fact that the emperor of the mountain is far away and suddenly becomes a new era in which no matter how high the mountain is and how far the road is, the Son of Heaven can also understand the people's feelings anytime and anywhere. Therefore, henceforth you must always be vigilant and be ready to go out with me at any time to patrol and fight. Previous foreign wars were largely just to make the conditions for change more relaxed, and you will be the real foundation for me to truly lead the change and defend fairness and justice! ”

Because there had been some briefing and preparation before, the teenagers in the new guard camp all understood what Xiao Xuan's words meant.
