In the Southern Song Dynasty, I competed with Mongolia for the world

Chapter 430 Your Majesty, please establish a prince as soon as possible

These two methods require many times to pull the rifling of a gun, and each time needs to be calibrated carefully, which is very time-consuming.

The second one is actually more practical than the first one, but the principle cannot be explained clearly by Zhao Yurui himself. After all, it all depends on his memory from reading the Internet in the past, and most people will not write in such detail.

Therefore, craftsmen have not developed the second type, and the first type also has many shortcomings.

The craftsmen's intention is to go all out to assemble the new Thundergon flintlock guns for now. After the entire army is equipped with at least 300,000 guns, they will then consider the issue of rifling.

Because it is enough to deal with the Mongolian army now.

Improvements can still be developed.

Zhao Yurui agreed with the craftsmen's ideas and praised and encouraged them: "You can brainstorm again and think of ways to pull out all the riflings at once."

If all the rifling can be pulled out at one time, there will be no need to worry about leveling or correcting it carefully, and both efficiency and performance will be greatly improved.

Of course there is such a method, but the craftsmen have not yet thought that they could research in this direction after Zhao Yurui reminded them.

This method of drawing out the rifling at one time is called the 'combined ring knife broaching method'.

The so-called 'combined ring tool broaching method' is to fix 25 to 30 carbide steel rings on a tie rod. The distance between each steel ring is equal, and each steel ring is processed with the same number of bore lines. For equidistant scrapers, each cutter can be connected to the cutter on the next ring along its winding angle, and the connection from beginning to end can be regarded as a spiral line.

The protrusion of the blade on each ring is slightly larger than that of the previous ring, forming a series of cutters. The grooves opened have stable width, depth and spacing. This combination of ring broaches passes through the gun bore once. Then all the bore lines can be cut, the working time is shortened, and the output and quality are improved.

This method is quite advanced. The width, depth, and spacing of the rifling are all fixed. There is no need to rely on manual proofreading, and there are no high requirements for the level of craftsmanship.

It was also the mainstream method later.

Of course, there are more advanced 'top cone (or rifling punch) extrusion JE method' and 'cold precision forging method' which cannot be realized in this era.

Combined ring tool broaching is possible.

Zhao Yurui's last scene was watching the so-called bullet.

But because the rifling cannot be determined, the development of bullets is relatively unimportant.

The Firearms Bureau made two types of bullets at Zhao Yurui's request last year, and then found that each has its own advantages and disadvantages.

The first type of bullet is like the historical Minie bullet. The shape is changed from a spherical shape to a cylindrical or pagoda shape. The bottom of the bullet is also added with a cork like the wooden cannonball. After the gunpowder is ignited, the cork expands due to pressure. , which makes the layers of the bullet expand and closely connect with the rifling, while increasing the air tightness and making the range longer.

The second type of bullet is to change the fixed-load ammunition into a paper-cased fixed-load bullet, which uses a paper tube to pack the excitation powder, propellant and warhead together to form an independent bullet shape.

Both types of bullets have their own merits. The former is more troublesome to make, consuming time, machinery, and materials, but it has good air tightness and a long range.

The latter is easy to make, but because the paper shell has poor airtightness and contains many impurities, it affects the range and accuracy. After firing about 20 rounds, the gun barrel must be cleaned thoroughly.

For flintlock guns that are loaded from the front, cleaning the bolt chamber is very troublesome.

After Zhao Yurui took a look around, he commended and rewarded each R&D team.

At the same time, because the rifling has not yet been determined, the requirements for bullets are not so urgent, which means that each team still has time to make modifications and upgrades.

In the words of craftsman Xu Li, it is best to change it to a rear installation.

There are many benefits to the rear mount. Firstly, it does not require a stabbing bar, which saves a lot of time in reloading. Secondly, it is easier to clean the bolt and it is also convenient for maintenance.

The problem that after-installation needs to solve is air tightness.

The Schneider rifle in the 19th century was fired by a flintlock and breech-loaded. His solution to the air tightness was to put the bullet and gunpowder in a small iron tube in advance, and then stuff it into the gun chamber from the back.

But Zhao Yurui didn't know the details, so he could only let the craftsmen continue to develop it.

At the same time, he decided in his mind that before the rifling standard came out, bullets would naturally not be mass-produced. If the standard rifling could be officially released and the bullets did not make progress, he might use minie bullets. Although it is more troublesome to manufacture, it is more airtight. Good, low maintenance and can hit farther.

That day, Zhao Yurui and their children stayed at the firearms bureau and craftsmanship bureau for another day. When they returned to the palace, it was time for dinner.

No matter how busy Zhao Yurui is, as long as he can make it in time, he will try his best to have dinner with his whole family at home every day.

He didn't have many concubines. After so many years since he ascended the throne, he was still married to the first few women, and there have been no more since then. There were less than ten wives and children, who could sit at the same table.

The courtiers now respect Emperor Zhao Yurui because he has not married a new person in the more than ten years since he ascended the throne. He lives a frugal and self-disciplined life and has the style of Ningzong.

But having said that, as an emperor, the courtiers also hope that the emperor has as many sons as possible, so over the years some people have been advising the emperor to have more children.

Currently, Queen Xie and Jia Yuhua are pregnant again, and it won't be long before Zhao Yurui will have another pair of children.

The next day, Zhao Yurui slept in and then came to Chui Gong Hall.

Today is the morning rest day. Except for those on duty, most officials in Beijing are on vacation.

Chui Gong Hall is where Zhao and Rui review memorials. There will be two to three people on duty in the cabinet today.

It was close to nine o'clock in the morning when Zhao and Rui came in, and others had arrived a long time ago.

"See your Majesty." Three cabinet members greeted Zhao and Rui.

"Good morning, dear friends." Zhao Yurui said with a smile.

The three of them also smiled bitterly, it was getting late.

Among these three people, only Deng Ruoshui is an old comrade, and the other two have already changed.

The former deputy prime ministers Ge Hong and Yang Changru died successively, and Zhao Rushu and Liang Chengda abdicated due to their old age.

Last year and this year, Zhao and Rui replaced a total of four cabinet members.

They are Cheng Gongxu, Li Pleiying, Liu Kezhuang and Huang Zhen.

Among them, Liu Kezhuang has served as a local envoy, and the youngest, Huang Zhen, was the top scholar in the new department last year and is currently the cabinet secretary.

Today there are Deng Ruoshui, Cheng Gongxu and Huang Zhen present.

Cheng Gongxu was a Jinshi for the fourth year of Jiading. He was quite young now, fifty-six years old. The year before last, he replaced the seventy-year-old Ge Hong in the cabinet.

Zhao Yurui has an age limit for cabinet members. Generally, the deputy prime minister or above must retire at the age of sixty-five, and the deputy prime minister or below must retire at the age of sixty.

Ge Hong and Yang Changru were members of the first cabinet, and they were always in good spirits. Zhao and Rui did not let them retire at that time, but both of them died in office.

After both of them died in office, Zhao and Rui reiterated that except for members of the first cabinet, all subsequent ones would have to retire.

At this age, Cheng Gongxu can still work for several years. He has served as a professor, county magistrate, and magistrate in the local area. In the capital, he has served as the director of Dali Temple, Dr. Taichang, and the minister of the Ministry of Rites. He is also experienced, both locally and in the capital.

This person also has a virtuous name in history. It is said in history that he had few desires and was only a child servant in his later years. His food was not rich in taste. It was not easy to get a fur for more than ten years. His family had no enviable savings. He respected and loved his relatives. He was also one of the talents recommended by Cui Yu and entered the cabinet after being reused by Zhao Yu Rui for more than ten years.

Huang Zhen was from Cixian County, Qingyuan Prefecture, Zhejiang Province. When Zhao and Rui were outsourcing in Qingyuan Prefecture, they recruited many young people, and Huang Zhen participated at that time.

This man was originally a late bloomer, and he was not awarded Jinshi until he was in his forties.

But after Zhao Yurui recruited him, he found that he was literate, polite, and upright, so he began to focus on training Huang Zhen among many teenagers, asking him not to join the army but to study literature.

Most of the young people recruited by Zhao Yurui in Qingyuan Mansion later joined the army. Huang Zhen was one of the few young people who studied in literature.

During the Yuanzhen period, Huang Zhen indeed won the first prize. He was only twenty-four or five years old at the time, nearly twenty years earlier than in history.

After Zhao and Rui met the three people, they began to read the memorial on the imperial case.

After his restructuring, the General Affairs Department arranged the memorials into categories, and then cabinet members previewed them first, sorting them from bottom to top.

Zhao Yurui read the military section of the Ministry of War first, as before.

At this moment, he was launching several armies to attack Mongolia. Many soldiers and horses were outside, and the news might not be sent back in time, so after a brief look, there was nothing important.

The only thing of any value is the Song army's conquest and occupation of Hanzhou (Feilubin).

In the second year of Yuanzhen, Zhao and Rui Kaikai conquered Feilubin and named it Hanzhou.

The first wave passed through 17,000 households, totaling 60,000 people.

The Song army was similar to the Spanish. It was easier to conquer the north but had greater resistance when attacking the south.

It took less than a year for the Spanish to conquer the north, and it took more than two hundred years to conquer the south.

There are many mountains in the south and there are many indigenous people, so the resistance is fierce.

Fortunately, the Song army's soldiers were more powerful than the Spanish. They were covered in iron armor and were almost invulnerable to the natives. They also brought a large number of dogs to explore the road, making progress much faster than the Spanish.

The biggest difficulty for the Song army there was the diseases in the mountains and forests, dysentery and other acclimatization.

Fortunately, Song Jun first stayed in Taiyuan Province for nearly ten years, and learned various experiences while fighting with the natives of Taiyuan, and was able to handle and adapt perfectly.

In addition, the Song army did not mainly focus on killing, but also used various goods such as iron pots and sugar to lure and try to build relationships with the indigenous leaders. This made it impossible for the indigenous people in southern Hanzhou to unite as one.

According to the latest memorial report from Zhizhou Chu Youcai, after nearly four years of continuous conquest, the southern natives finally decided to surrender to the Song people in March this year and expressed their surrender. Chu Youcai briefly counted the local population and reported in June, Now we have arrived at Zhao Yurui's desk.

Zhao Yurui was overjoyed when he saw this. He quickly got up, ran to the map behind him, and drew a lot of Hanzhou.

From now on, the entire Hanzhou belongs to the Song Dynasty.

Obtaining Hanzhou will be of great benefit to the next step of entering Malacca.

Hanzhou is used as a springboard. The next step is to attack and conquer Bo Ni (Wen Lai), and then it will be too late to be close to Singapore, Malaysia and Thailand.

Zhao Yurui returned to his seat and immediately wrote a reply.

First, he commended the soldiers and civilians of the Song Dynasty in Hanzhou and promised to give them material rewards.

Then let Chu Youcai build a new shipyard in the southern part of the area, mainly hiring local indigenous people to complete the work, and trading in their favorite iron pots and white sugar.

The naval forces in Hanzhou all came from Dayuan and Hainan during the Song Dynasty, and they had to go back to Dayuan for repairs.

Because there was no time to build a shipyard in the past few years, now that the indigenous people have been pacified, a new shipyard can be built, and new ships can be repaired and built on the spot in the future.

After Zhao Yurui finished writing the reply, he went to the map to look at it again.

In fact, he really wanted to attack Annan and Champa and other countries on the left, but these places are now far larger than Balni.

After the Yuan Dynasty destroyed the Song Dynasty, they conquered Annan in all directions, but all ended in failure. Although the Ming Dynasty briefly conquered Annan, they had to give up in the end.

Now that Zhao and Rui are in full-scale war with Mongolia, there is really no need, and they do not have the energy and strength to conquer Annan at the same time.

Bo Ni in Hanzhou was the training ground for the Song army. The combined population of these two places was not as large as that of a Champa city, let alone Annan.

Chu Youcai counted the indigenous people in Hanzhou. Currently, they can count about 30,000 households and 150,000 people.

Considering that there are still those hiding in the mountains deeper in the south or north who have not come out, the total number of natives in Hanzhou will not exceed 200,000.

The population of Balni is smaller, with less than 100,000 people in the whole country, of which 10,000 are concentrated in the capital. As long as their capital is broken, Balni will be doomed. Of course, there are indigenous people in the Balni Mountains, but there will definitely be no Han people in total. There are many people in the state.

To attack a small country like this, you can mobilize hundreds of ships and thousands of people. There is really no need to attack Annam Champa first.

The number of indigenous people in Hanzhou is quite surprising.

There are several types of data available online. One is that during the Ming Dynasty, there were about 900,000 people in Hanzhou.

Another data is that during the medieval period, Hanzhou and the Innis Islands were about two million.

The Middle Ages also included the Song, Yuan and Ming dynasties.

Comparing it with the current statistics of about 150,000 people by Chu Youcai, it is difficult to say whether it is accurate or not.

But what is certain is that after the Song Army conquered the south, there are still large areas in the south that the Song Army cannot reach.

The next moment, Zhao Yurui planned to lure the natives out and let them work in the fields, grow sugar cane, and produce sugar, so that there would be fewer and fewer natives in the mountains, and the population statistics would become more and more accurate.

Returning to the imperial court again, Zhao Yurui wrote another letter to the local navy general Ruan Heng, indicating that he could recruit 5,000 troops from the local natives and train them for one or two years to prepare for the next attack on Bo Ni.

Zhao Yurui wrote something very quickly. In just a few words, the secretary Lang Huangzhen immediately took it and sealed it. Then the servant outside the palace and the sergeant of the Imperial City Department took it out and handed it to the General Affairs Department.

Huang Zhen will also write two copies of the content, one is kept in the General Affairs Department, and the other is kept in the Chui Gong Hall of the Cabinet.

Otherwise, if someone replaces him in the middle, it may be another story when it reaches Hanzhou, and the general on the opposite side will be in trouble.

If Ruan Heng returns to Beijing in the future, he will bring back all the letters he received from the emperor and the court during his several years in Hanzhou, and then compare the copies one by one to see if there are any errors or omissions.

Ruan Heng, after receiving the original copy, will also make a copy and keep it as a backup.

After Zhao Yurui finished handling the military memorials, he came to the memorials about the Ministry of Rites and Miscellaneous Affairs. He originally arranged this category at the end, but the first one was too conspicuous.

"Your Majesty, please establish a prince as soon as possible." I saw a few words at a glance.
