Li Weiguo designed and manufactured the first rifle in the real sense, because he himself played with guns and knew the structure of the gun very well, so it was relatively easy to catch it.

However, for artillery, Li Weiguo is not so good, compared to him has never played with artillery, and it is impossible to disassemble and assemble cannons like disassembling guns, and he does not understand the various parts inside the cannon, and only stays at the level of ordinary people's basic understanding of artillery.

In this way, it is very difficult for Li Weiguo to design and manufacture an advanced artillery gun in the modern sense.

Fortunately, Li Weiguo is not the kind of person who is eager for quick success, he is very patient, since he cannot design and manufacture an advanced artillery in a short period of time, and there is a lack of professionals who are proficient in artillery structure, he can only put it for a while, and then start developing new artillery when he is ready.

However, Li Weiguo was always a little unwilling, he couldn't design advanced artillery for the time being, but the advanced gun carriage was relatively simple.

At present, Li Jiajun uses British-made front-loading smoothbore guns, and there is only a simple brake and retreat machine on the supporting gun carriage, which is a spring-type structure, and in actual combat, this kind of brake and retreat machine does not work at all, and as soon as the cannon is fired, the gun carriage still jumps up or is shaken back by recoil, which makes it difficult for the artillery to accurately hit the target.

Li Weiguo obviously understood the hydraulic structure, so he converted the spring-type brake and retreat machine on the gun carriage into a hydraulic brake and retreat machine, and such a small improvement made the gun instantly become much more stable when firing. At the same time, Li Weiguo installed two support arms on the gun carriage to fix the gun and prevent the gun from jumping when firing.

It was these two inconspicuous and simple improvements that greatly increased the firing speed of Li Jiajun's artillery. In the past, the position of the gun had to be re-fixed every time a shot was fired, but now there is a hydraulic brake and two iron support arms, so that the gun does not need to fix the position of the center of gravity after firing, which saves a lot of time and greatly improves the firing speed and efficiency.

In the Jiangnan Manufacturing Bureau, which was responsible for the production of weapons and ammunition, Li Weiguo made improvements to guns, bullets, and artillery, and then began to improve the gunpowder formula.

At present, the armies of all countries use **, although in the gunpowder formula, the armies of all countries are different, but they are all the same, and the difference is not big.

The first thing Li Weiguo had to do was to replace it with smokeless gunpowder, because a large amount of black smoke was produced after shooting on the battlefield, which affected the observation and aiming of soldiers and was not conducive to combat.

Smokeless gunpowder is nitrocellulose, which has long been invented abroad, but because it is unstable, the armies of the great powers of various countries are not equipped.

However, for Li Weiguo, this is not a problem, only need to dissolve the nitrocellulose in ** and ethanol, and then add an appropriate amount of stabilizer to it to make it a gelatinous substance, which can be made into smokeless gunpowder by pressing it into sheets, cutting strips, drying and hardening.

Smokeless gunpowder in history first appeared in 1884, and after 1895, it began to be widely used in armies around the world.

The basic ingredient of smokeless gunpowder is nitrified nitrogen, and its industrial raw material comes from nitrate, which is basically imported from Chile in South America, and will continue until after World War I according to the historical development trend.

This is because the technology of large-scale industrial nitrogen extraction has not yet been mastered by the great powers of various countries, Li Weiguo knows that the best way to extract nitrogen directly from the air is the best way, but at the moment he also needs some nitrogen production equipment, and at the same time large-scale cheap extraction of nitrogen from the air, if this is known by the great powers of various countries, it will have an indefatigable huge impact on the historical process of the whole world, because it will accelerate the military industry of various countries, especially Germany, if Britain, France and the United States did not blockade Germany's import of nitrate from Chile in World War I, Germany itself will be able to extract cheap nitrogen on a large scale, and the course of the war will be very different.

Therefore, Li Weiguo is very careful, he knows that every time he allows advanced technology and equipment to appear in this era in advance, it will change the course of history, with the current national strength of China, it is simply impossible to compete with the European and American powers in industry, once these advanced technologies are mastered by the European and American powers, the benefits they get are obviously far greater than the benefits Li Weiguo gets, which is not allowed.

Because Li Weiguo is not a person who is willing to suffer losses at all!

Secrecy has become something that Li Weiguo must do with great effort.

To this end, Li Weiguo must first set aside an industrial zone and implement militarized management, and the personnel inside must ensure that no news is disseminated, which requires considerable time and energy.

Therefore, although Li Weiguo has developed smokeless gunpowder, he did not immediately start large-scale production, but first prepared a highly secret military base similar to the 51st Area of the United States in the future, which is not only a secret for the technology of large-scale production of industrial nitrogen, but also more advanced technology and equipment that need to be kept secret in the future, and will be arranged in this secret military base.

To build such a military base, it is necessary to keep it secret and be able to carry out industrial production, Li Weiguo has not come up with it for a long time.

Fu Shanxiang saw that Li Weiguo was worried and stumped by things, so he proposed to accompany him to walk around, maybe he would come up with a way as soon as inspiration came.

Li Weiguo knew that his wife had good intentions, so he nodded in agreement, and the two didn't go far, Yu Garden itself covers an area of more than 70 acres, with dozens of beautiful scenery. As Fu Shanxiang became the hostess here, she changed the Yu Garden every day, decorating her home more and more beautifully, with both the palace-like magnificence and the natural beauty of the Jiangnan garden, which can be described as a fairyland on earth.

The two came to Yuyuan Lake Island, Fu Shanxiang renamed the Lake Island Penglai Yaochi, she didn't know where to get a design drawing of Pengdao Yaotai in the Old Summer Palace, so she invited craftsmen to imitate.

Li Weiguo saw that Fu Shanxiang was so bold that he dared to imitate the royal garden, it can be seen that what is called a husband and a wife, the husband wants to be the emperor, the wife builds the royal garden, and works together in everything, this is the real husband and wife.

Li Weiguo was happy in his heart, and suddenly an inspiration came, inspired by the island in the middle of the lake, and being isolated from the world is not exactly a prerequisite for building a secret military base.

Li Weiguo immediately ordered someone to get a map and look for the island in the middle of the lake in his own territory.

Soon, Li Weiguo found that there was an island in the middle of the lake in Taihu Lake - Baoshan Island (now Xishan Island in Taihu Lake), the area was large enough, the island was surrounded by mountains on all sides, the mountains were not high or short, it was suitable for building fortresses and fortifications, and there was a large piece of flat land in the east, which was more than enough for the construction of twenty or thirty large factories. The island is surrounded by water on all sides, which can block external contact, and Taihu Lake is directly connected to the Huangpu River to the core of Shanghai, which can deploy a naval army to block the island in the middle of the lake, and at the same time facilitate the transportation of various materials produced in the industrial area on the island.

This is really a godsend, and Li Weiguo immediately decided to use Baoshan Island as a secret military base.

Li Weiguo found Wu Yong and Fu Xuexian, told them his ideas, and got the approval of the two, so he immediately began to implement them.

There is a small town and six villages on Baoshan Island, with a population of about 3,000, and Li Weiguo ordered the Suzhou government to complete the land acquisition work on the entire island within a month.

The efficiency of the Suzhou government was not bad, and the population of the entire Baoshan Island was quickly moved, and then Li Weiguo sent 10,000 land and water troops to Baoshan Island and began to build fortresses and military bases.

Li Weiguo renamed Baoshan Island as Alcatraz Island, in addition to his personal little bad taste, but also to warn the nearby residents that residents will generally not approach when they hear the three words Alcatraz, plus military control, those who approach without permission will be killed, and over time, no one will dare to approach Alcatraz Island again, so as to ensure the secrets of the island to the greatest extent.

There are more than a dozen satellite islands near Alcatraz Island, and Li Weiguo sent his navy to build watchtowers on these small islands, which are high enough to overlook the surrounding water for dozens of miles. At the same time, a water village was set up on the island, and a naval army was stationed for a long time to patrol Taihu Lake and expel ships and personnel who tried to approach Alcatraz Island.

After his investigation, Li Weiguo built forts and placed 22 32-pounder fortress guns in the east of the island, Jushan and Xie Gu Mountains, Maohuding and Duzhu Mountains in the north, Baiyun Mountain, Shetou Mountain, and Mawang Mountain in the west, and Maoshan, Turtle Mountain, and Nanwan Mountain in the south. The central main fortress fortifications were built on the central Dakun Mountain, four 64-pounder heavy fortress guns were placed, and a military camp was built at the bottom of the mountain, with 2,000 troops stationed all year round, to protect the security of the Alcatraz military base.

Construction of the entire Alcatraz military base began in three phases, which is expected to take two years to complete. At the same time, Li Weiguo also first placed a nitrogen factory, a sulfur and nitric acid factory, and a smokeless gunpowder factory on Alcatraz Island, right under the nose of the military base. In addition to the ready-made industrial equipment for the nitric acid and sulphuric acid plants, the machinery and equipment for the nitrogen plant and the smokeless powder plant are under development and production, and it is expected that it will take one year to put into production and use.

Just when Li Weiguo was planning the Alcatraz military base, Xiaohe, the personal maid of Shen Ziyan, the Shen family's young lady who had not seen him for more than half a year, suddenly came to Yu Garden to find Li Weiguo.

Li Weiguo was very disgusted with this little girl who was loyal to the Lord at first, but now he admires her very much, and the more he looks at her, the more pleasing it is, and immediately calls her in.

"Young Master Li, my young lady is in trouble, please save her!"

As soon as Xiaohe came in, he cried when he saw Li Weiguo, and he was suddenly frightened by Li Weiguo's spirit, and his heart suddenly sudden, and he hurriedly asked, "What's wrong?" What's wrong with your lady? ”
