Zi said: "If you want to do a good job, you must first sharpen your tools."

Li Nan, who came from later generations, although he was not a politician or military strategist, knew early on that in addition to soldiers and commanders, logistics and equipment were also the top priorities in war.

The arsenal set up in Guangyuan Prefecture has been relocated here from Guangnan West Road for several years.

When this arsenal was first built, there were not many craftsmen, and they only relied on the "Book of Native Grenade Manufacturing" that Li Nan got from the system.

However, since Ashur brought back a large number of craftsmen from the city of Tokyo, thanks to the generous rewards and treatment of craftsmen and inventions in Jinnanguo, these humble craftsmen, who had been despised by the upper class, have shown unprecedented creativity.

Li Nan originally thought that the craftsmen of the Northern Song Dynasty used simple tools to work, but later he found that he underestimated this era and those skilled craftsmen.

Today's Guangyuanzhou Arsenal has thousands of rotary lathes of all kinds, and the hydraulic stamping machinery built by the river is also quite large-scale.

In fact, the most basic principles of gunpowder and firearms have not changed since ancient times.

All firearms use the barrel to close the gunpowder deflagration, and the volume is violently expanded to produce a high-temperature and high-pressure gas to erupt forward, pushing the projectile to move at high speed, and then relying on the projectile to hit and kill the target.

According to the history of the development of muskets, there were once muskets, arquebuses and flintlock pistols in terms of design and equipment; Distinguished by whether the barrel is rifled or not, it can be divided into smoothbore guns and rifles.

Since the Guangyuan Prefecture Arsenal, with a large number of machinery and enough manpower, now has begun to assemble line operations, and after continuous research and improvement, now the production here is not the first generation of firearms, but beyond the arquebus flintlock pistol.

The front-loading smoothbore rifle, named 'Southern Fire Snake', has a caliber of between 16-22 mm, weighs 4-6 kg, is about 1200-1600 mm long, and can reach a range of 140-200 meters.

Even though Ruiwen and others, who also came from later generations, introduced the role of barrel rifling and used AK rifles as models, the craftsmen of the arsenal were unable to make suitable barrels in large quantities.

After visiting the arsenal, Li Nan also tried to use this mass-produced smoothbore rifle, and a sense of pride rose in his heart.

Although this smoothbore gun is not very accurate, but with a design distance of more than 100 meters, if the soldiers are in a reasonable formation, it will be enough to deal with the powerful cavalry of those northern countries.

After leaving the Guangyuan Prefecture Arsenal, Li Nan inspected various schools in the five provinces of Zhennan.

In Li Nan's territory, the setting of the school is also completely different from Song Liao.

The main task of the primary school is to teach the people to read and write, but other schools do not have temporarily useless subjects such as the Four Books and the Five Classics, but add more practical knowledge such as mechanics, mathematics, physics and chemistry.

According to later generations, these schools were equivalent to technical schools.

Although there is something wrong with this teaching setting, it is in this stage where there are enemy countries on all sides, and it is the most important thing to be able to quickly cultivate students with a skill.

There are not many standing troops in Zhennan, and there are currently 10,000 elephant slaves and 50,000 war elephants, and 4,000 heavy armored infantry.

The main force was the First Infantry Regiment of the Zhennan Army led by Spartacus, with 20,000 divisions under its jurisdiction. Kress's 2nd Infantry Regiment of the Zhennan Army also had 20,000 divisions.

The Germanic brothers Juno and Elican were in charge of a special division of the Zhennan Army consisting of 3,000 archers, 5,000 projectile vehicles and eight-bull crossbow troops.

If Li Nan wants a full-scale northern expedition, then the 50,000 war elephant legions, which have the strongest combat effectiveness, must be excluded first.

These war elephants are indeed powerful, and when paired with enough firearms, they can be called the ancient version of mobile war fortresses, and 50,000 war elephants can sweep away any army if nothing else, but from the actual situation, this is not the case.

These war elephants have always lived in tropical climates, so if they go north, they will have to deal with the weather.

Secondly, elephants have to eat hundreds of catties of food every day, if there is no good care, it is difficult for elephants to survive in the north, the cost of raising an elephant in the north is higher than 100 cavalry, higher than 500 infantry, and it is not possible to fight in winter.

After removing the War Elephant Legion, Li Nan's available troops are only about 50,000, which is quite a lot in the Lingnan region, but thinking of the vast territory of Song Liao and other countries, these soldiers may not be enough to garrison the occupied cities.

It is not easy for those in power, they need to face too many problems, and since they report to Li Nan, they are basically difficult problems.

"It looks like we can only conscript!" Li Nan thought about it for a long time and finally made this decision.

After all these years of reproduction, Li Nan bought hundreds of thousands of homeless people from Fang La's hands, and now there are quite a few people in Zhennan.

Li Nan, a Song man in the territory, did not dare to use it, and it was probably not a good idea to let these people join the army to attack their motherland, so the scope of this conscription was Jiaozhi, Dali Bai and Lingnan, adult men between the ages of eighteen and thirty.

It will take more than ten years to train a qualified archer, but it will only take a few months to train a musketeer.

In just three months, Li Nan transferred the experienced grassroots officers of the First and Second Army Corps, recruited 60,000 recruits, and formed three other infantry corps.

Spartacus's position did not change, he was also the commander of the First Infantry Regiment of the Zhennan Army, and the adjutant general Dadao Guan Sheng was added.

In the Second Infantry Regiment of the Zhennan Army, Kress also joined the adjutant general.

King Leonidas from Sparta was the commander of the 3rd Infantry Regiment of the Zhennan Army, and Baroness Sienna was the lieutenant general.

Pang Wanchun, the king of the Divine Arrow, became the commander of the Fourth Infantry Regiment of the Zhennan Army, and Zhu Tong, the bearded prince, became his lieutenant.

The leopard head Lin Chong was appointed by Li Nan as the commander of the Imperial Forest Legion, and Huang Xin of Zhensanshan, Peng Yu, the general of Tianmu, and Mary the female fox all became the partial generals of this special army.

In addition to the regular 20,000 soldiers, the Royal Forest Legion also added a thousand armoured war elephants, dozens of terrifying giants, and hoplites with bullroar, which increased to 5,000.

After the establishment of these new legions, they were training hard every day, and what they lacked was the tempering of blood and fire, and this kind of thing could not be obtained at home, so Li Nan looked to the north.

Zhang Shuye in the Great Song Dynasty is also very busy now, because Zhennan has never attacked the border, so the Song army has lost its vigilance against the south, and the Song army is now focusing on encircling and suppressing the Fangla army.

Since Fang La was defeated in Hangzhou by the 150,000 western army led by Tong Guan and Tan Zhi, two eunuchs in charge of the army, he was defeated in even battles, but did not flee to Bangyuandong as recorded in history, but fled to the west of Sichuan after a false shot on the Fujian Road.
