The Jesuits got the news they wanted, they just need to know that China's book ban is not aimed at the Holy See, and they can continue to preach, as for science and technology books, they don't care too much, and Jiang Tian's explanation to them is: In order to prevent China's atheist works from affecting foreign countries, and in order to maintain the stability and unity of friendly countries, China prohibits some things that excessively propagate science and deny religion from flowing out of the country. The two missionaries were simply moved by this, because in Europe it is precisely because the development of science has had a great impact on the Holy See, and the kings and lords of various countries have more support for science and technology because of the needs of reality, and the social atmosphere is also more fond of the progress of various knowledge, so even if the Holy See can still control some public opinion, it cannot stop this general trend. At the end of the day, when religious and secular interests conflict, God has no choice but to make way for his own lost lambs. However, Jiang Tian gave a solution, if the Holy See encounters some people who are more famous and difficult to start, but who despise the Inquisition, they might as well throw him on a merchant ship bound for China, and say to the outside world that this person has gone to the East to study......

Jiang Tian didn't expect the Holy See to really do this, it was just a casual remark, don't look at the great pioneers of Europe now who are eager to learn from China in their own countries, and also engage in the rule of literati and scientific examinations, that is, they have the same virtue as those elites on the Internet in later generations, but if they really let them travel thousands of miles to China to collect style, it is estimated that not everyone is willing to take risks such as piracy and shipwreck. Unless the spread of Chinese technology and culture to Europe has a huge impact on these people who ignore the danger and come here to make a pilgrimage, it will not be too attractive to European literati. And this possibility was also sealed by Jiang Tian. Of course, the later development did not follow Jiang Tian's script, he originally planned to let the Europeans continue to immerse themselves in the excitement of the Renaissance, but did not point out any direction for them, and after our development far exceeded their technological level, they would crush their colonies with powerful force and cheap goods, and finally complete the world domination. It was only later that as Chinese merchants began to widely participate in ocean trade, there were always some people who unconsciously took some books out, and finally a junior high school physics textbook attracted the attention of European scientists, who found that this book for the enlightenment of minors was far beyond their understanding of the world, and some people who came to China to study also copied some cutting-edge research results in their native language in disguise, and finally the Japanese and Koreans completed all the leakage work. The entire European scientific community was simply shocked when they learned of these contents, and they suddenly found that what they were studying had already been concluded, and the Chinese just disdained to share with these backward barbarian peoples, and since then a large number of pilgrims have flocked to China, many of them have started sects in another time and space, and most of them rarely return to Europe, according to a person who later became a lifelong member of the Royal Chinese Academy of Sciences, the reason why these foreign students did not return to their homeland, Even most people have sharpened their heads to join Chinese nationality, just because without this premise, they can't get access to real high-end content at all. Especially after being qualified to consult top-secret materials, I realized that the research I had done all my life was just to provide evidence for Jiang Tian's theory, and the huge amount of money allocated by China to the Academy of Sciences every year was simply unbelievable, not any country could spend 6% of its GDP on scientific research in this era!

Of course, this qiē only began to happen decades later, Jiang Tian did not know that there would be so many people who would rather commit treason than come to China to study, let alone that later generations would worship him as a god in the scientific community, as for how many people in later generations suspected that he was a traverser, there are countless research reports, and later the crime of banning the flow of Chinese scientific works to Europe was also logically detained on the head of the Holy See, anyway, he didn't have to worry about it. But he was still very excited, and before the first day of the Lunar New Year, he hurriedly changed his clothes to greet the emperor, so that Liu Baokai and Song Yi, who came to invite him in the morning, pounced. Why is Lord Jiang so excited? It was because he was holding the portrait of the Virgin as a greeting gift. Zhang Tao was not an uninformed Chinese literati, and after seeing this painting, he understood what Jiang Tian had in mind, so he agreed to introduce the mention of "Anatomy" without waiting for him to sell it. As for the accusation that the destruction of the body was caused by Gan Tianhe, he also found another solution. Since then, all condemned prisoners have been accepted by the Institute of Medicine, which is under the umbrella of the Academy of Sciences, which is responsible for perfecting forensic science and surgical techniques and studying the mysteries of the human body.

Because not many people know about this matter, and no one cares about the human rights of death row prisoners, and there are a large number of corpses on the battlefield to provide materials, the originally slow development of Chinese medicine has begun to speed up, and the revival of surgery has gradually perfected medicine, and finally developed another modern medicine. The progress of medicine led to the increase in the life expectancy of the population, followed by a substantial increase in the population base, a sharp decrease in the battlefield casualty rate, and an exponential increase in comprehensive national strength, so that China had enough population to fill the vast territory, avoiding the embarrassing situation of the British who controlled a large number of colonies with a few hundred soldiers. It also avoided the defection of the colonies after the decline of the British national power. Therefore, in the future, even if the descendants lose the throne of the world hegemon, they will not be reduced to a second-rate country.

Children and grandchildren have their own children and grandchildren, Jiang Tian can't manage the things in a few hundred years, although he is now on winter vacation, but because he is a student, no matter where he is from, except for some people whose ancestral home is Hebei, most of them stay in the capital for the New Year, so every day just the students who come to visit the New Year in groups can't cope with it. Fortunately, no one made it difficult for him at this year's Spring Festival group meeting, and last year's two poems by him and Zhang Tao shocked the Sauke community, and no one dared to challenge him this year. However, Jiang Mansion's fireworks and firecrackers this year are particularly different, Jiang Tian modified some rockets that failed to test, and the fire @ explosives @ medicine of the warhead were replaced with fireworks bombs, and as a result, the fireworks of Jiang Mansion went straight to Xiao Han and exploded The fireball can be seen throughout the capital. Such a windy fireworks simply covered the royal family, and some people held back to impeach him for overstepping the system, who asked you to put the fireworks higher than the palace? But Zhang Tao just raised his eyes to look at the beautiful sparks, and did not pursue his public and private use too much, but just reminded him not to do this in a densely populated city next time, in case a dumb fire falls down and it is easy to cause a fire. And the punishment for Jiang Tian is...... Originally, the private dinner of the Lantern Festival was cancelled, and you were limited to completely finalize the design of individual bazooka and small-caliber mortar before the end of the winter vacation, otherwise you will be fined for half a year!

This is simply not a punishment, who doesn't know that since the glass factory started, Jiang Tian's account is simply a daily income, even if the investment in expanding reproduction is deducted, he can be regarded as a wealthy man. What's more, the original chicken ribs of the lead movable type began to shine, the new version of the lead printing book in the quality completely exceeded the watermark wooden movable type, the printing efficiency is doubled, so that many large study halls, printing halls have begun to use the lead movable type printing line, here alone the patent fee is more than the imperial court. If he, Jiang Tian, still cares about that little money, he will be the number one scientist in the world in vain. However, from Zhang Tao's order, many people sniffed out some differences, first of all, Jiang Tian has developed some kind of new weapon, and it seems to have reached the point where it has been basically completed. Many people are already thinking about how to rebuild their efforts in the shipping industry. Then there are those Japanese and Koreans who came to study abroad, they also saw Jiang Tian's fireworks, at first it was a limited edition customized by their teacher in order to show the style, and later they realized that these were just waste utilization of failed products, and the fireworks that exploded in the sky @ made some knowledgeable people feel cold. This thing can hit so high just by firing it into the sky, how many shots will it take at the enemy if it is flat? The idle army may collapse directly.

The Koreans are no strangers to gunpowder weapons because they have used a large number of Ming-made rockets, while the Japanese are because the chaotic era has just ended, and the samurai are quite sensitive to any military changes, so these two groups of people are salivating when they look at the rockets that are about to be finalized. Neither Jiang Tian nor Zhang Tao actually planned to keep the rocket secret, if some friendly countries want to buy it, it is not negotiable, provided that you can afford the high purchase price. Jiang Tian calculated that the production cost of an 80-mm individual rocket was nearly five taels of silver, and the external price was at least ten taels, mainly because the production of galvanized sheets was not large-scale, and the conditions for large-scale equipment were not yet available. Anyone who hears this price is prohibitive enough. This is not counting the maintenance cost of one or two taels of silver per year after buying it back, to put it bluntly, as long as you don't buy it and use it immediately, the money still has to be spent like a stream.

However, the rocket artillery finalization test still attracted a lot of people to visit, including military representatives, political bigwigs, and some potential buyers and spies. Jiang Tian dared to openly test, in addition to the stability of the system, he was also more sure of the difficulty of replicating the manufacturing technology. Imagine who in this era can make ultra-thin galvanized sheets, passivated propellants, fire@explosives@charges, and the most basic aerodynamics? Except that China does not make a second choice. Even if the enemy gets a sample, it can't reverse copy something with the same performance. This is the same as the police of a certain world in another time and space often revealing some of their own cutting-edge weapons, that is, they are not afraid that you will steal the master, and you will not be able to build them anyway.

This time, two types of rocket artillery were mainly finalized, one is a single soldier bazooka appointed by Zhang Tao, this thing uses a reusable launch canister, and a super-caliber charge, the shape looks very much like an alternative RPG, a huge warhead exceeds the diameter of the rocket, so the final direct shooting distance is only 100 meters. The shooter team is divided into two parts, the rocket bearer and the ammo man, who is not only responsible for carrying spare rockets, but also for igniting after the rocketeer has taken aim. This time, the bazooka was placed on a sturdy tripod for safety, and the ammunition operator took refuge in a nearby blast pit after igniting it. I saw that suddenly a thick smoke burst out, and the rocket went straight to a low wall 100 meters away with a unique scream, and at the moment when the warhead hit the wall, the fire cap ignited, and after a loud bang, the brick chips flew sideways, and the blue brick wall that originally looked very solid was blown out of a big gap.

"Ladies and gentlemen, I wonder what you think about this?" Jiang Tian deliberately showed off and said to the civil and military officials who came to watch: "The power is not bad, but this thing is a little expensive." ”

Unlike the generals who were excitedly gearing up, Zhang Tao nodded expressionlessly in recognition of this design. On the civilian side, especially the Confucian scholars led by Ning Jiao's diehards, they looked at each other one by one, none of them thought that this thing was a half-baked work that Jiang Tian was not satisfied with. Although the power will not make a big hole in the city wall, it is no problem to blow up the city gate or suppress the city head. If Jiang Tian and the emperor were not satisfied with this thing, then what did they want to make?

Before their heads could turn the corner, a new test began at the test site over there, this time a twelve-tube launcher, and the shooter responsible for connecting the lead was busy for a long time, checking the firing angle and timing the fuse. This kind of large-area covered rocket artillery, Jiang Tian didn't dare to have the luxury of replacing it with a **trigger fuse, and that thing was not complete. So he used a fixed time-delay fuse, to put it bluntly, it is a fuse of different lengths, and it is bound according to the approximate distance before launching, although it is troublesome but saves costs. Immediately after the ignition, twelve rockets were fired out one after another, needless to say, the shocking effect of the momentum, and the dense smoke could not be dissipated for a long time. Zhang Tao's eyebrows jumped slightly, and he finally had the feeling of returning to the original time and space to operate the rocket artillery. Although this kind of normally charged rocket is not as powerful as the previous one, it is better than the salvo effect, and a dummy a kilometer away is instantly obscured by the smoke of the explosion, and you don't need to look to know that the group of dummies imitating the enemy's formation is absolutely wiped out. This time, not to mention the civilian officials, even the military generals were silent, and in the face of scientific power, personal martial arts have become very small. After a while, several soldiers retrieved a tattered armor from a distant target, this standard Ming army iron armor obviously has a few eye-catching holes, at first glance it was caused by the flying shrapnel, just when everyone was amazed by the power, Jiang Tian shook his head slightly, the charge is still a little less, and the shrapnel fragmentation is not satisfactory, if it is not for the pre-loaded lead bullet in the warhead, the hard target against the armor will definitely not have the current lethality.

Although Jiang Tian was not satisfied with this rocket, who would dare to question that this was a defective product? If such sharp weapons had appeared a few years earlier, what if there were such things on the front line of the Yangtze River? If the armies of the Northern Expedition had the individual rockets that opened the mountains and cracked the rocks? Or a little earlier, the first-line defenders of Guanning will rely not on red-coated artillery, but on this kind of rocket artillery...... Zhang Tao didn't bother to explain anything to these group of hindsight, he was born in the revolutionary army, he absolutely believed that people are the key to war, although technical weapons can improve efficiency, but what is the use if they are as afraid of the enemy as the Guan Ning army. The civil servants were then invited out of the testing ground, and the generals stayed behind to continue to accompany the emperor in reviewing the new weapons. When the idlers and others all left the weapons test site directly under the Academy of Sciences, Jiang Tian took out today's protagonist. If the rocket is the crystallization of high technology, although the utility is extraordinary, due to the high price, it cannot form a quantitative advantage. So a kind of alternative weapon that can be widely equipped but affordable is much more important than the seemingly tall rocket, and this kind of thing is Jiang Tian's improvement based on the new artillery of the old man Song, there are a total of three products: hand cannon, squat cannon, no conscience cannon!

When Zhang Tao heard this name, he almost didn't laugh out loud at that time, and said in his heart, you are a half-military fan, and you dare to get an axe, I don't know Lao Tzu, I was born in Huaye in my last life? When you played the No Conscience Cannon, you kid wasn't born yet! But this is just the words in his heart that he didn't say it, since he knows Jiang Tian's improvement ideas, he can wait for him to introduce them. But after listening to it a little, he felt that he still underestimated this fellow, if he was playing an ancestor without a conscience cannon, then after being improved by Jiang Tian, two kinds of apprentices and grandchildren appeared.

The so-called hand cannon, this is a hand-held steel made of steel with a caliber of about 60 mm, the bottom of the steel pipe is sealed with a fire door, you can place a standard thunder @ mercury fire cap or red phosphorus fire cap, the tail sticks out of a wooden butt, which can be used to cover the shoulder, the overall shape looks very similar to the grenadier barrel of the devil back then, but because of the lack of brass, so it is still used to set the cartridge with a paper shell, and when the bullet is loaded, it must be compacted with a whole strip, and the protrusion in the chamber squeezes through the bullet shell to expose the propellant, and finally knocks the fire cap to complete the firing. The warhead completely adopts a simple timed delay fuse, which requires high training of operators. The advantage is that the rear-seat can shoot in the trench, forming a kill within 50 to 100 meters, similar to the individual grenade launcher of later generations.

As for the squat gun, it is actually an enlarged version of the grenadier canister, but the caliber has become 80 mm, and then people can't carry it, so it was replaced with a disc-shaped base, with a simple fixed-height tripod, the shape is similar to the mortar of later generations, the use of iron shell ammunition with bullet wings, with a qiē characteristic of modern mortars, the only drawback is that the firing rate is low when using the red phosphorus fire cap, and the shooter is often responsible for eliminating the dud, and does not have the ability to fire flat. The maximum firing range does not exceed 600 meters

Finally, and most importantly, Jiang Tian named the thing that has no conscience, so that Zhang Tao gasped when he saw it, this is a thing that is biased towards a 120 mm heavy mortar in shape, because of the practical steel barrel, so the weight is lower than that of a bronze cannon, and the most important thing is that Jiang Tian gave this gun the ability to fire flat, and it was inspired by individual rockets, this gun can fire super-caliber heavy shells, the diameter of the shell is greater than 160 mm, and the maximum range of ordinary shells is only one kilometer, as for the power...... The generals present did not dare to think much about it.
