Guo Shoujing, the secretary of the Tongzhi Taishi Academy, likes to study the astronomical calendar the most in his life, and the vast night sky is his favorite------- everything and mundane things in the world are really not worth mentioning compared with those stars, the sun and the moon!

No matter what the Great Jin Dynasty, the Great Yuan Dynasty or the Great Song Dynasty, as long as he can study the astronomical calendar that he likes the most, whoever is in power can ------ what makes the difference? ?

But the pirates are the most hateful!

They influenced their own research!!

Guo Shoujing carefully studied the fire and medicine paid tribute by the Great Song Dynasty, and observed the gunpowder craftsmen offered by the Great Song Dynasty------ and slowly he discovered the mystery!

He was far more invested than the craftsmen who knew it but did not know why, and soon, he wrote a booklet "The Art of Gunpowder", which immediately improved the processing technology of high-quality black fire and medicine.

He also devoted considerable energy to the study of arquebuses and artillery, as well as grenades and bullets.

He put all the effort he put into designing all kinds of elaborate astronomical observation instruments, and after he modified them, they were more dexterous and accurate.

He can even design it himself based on some rumors!

For example, rockets, and sliding rocket torpedoes used on the water------ which he once tested in calm pools on the surface:

He found a craftsman to carve a fish-shaped wooden plank, installed a few spikes at the fish's mouth, mounted the rocket on the plank, and after igniting, the plank slid forward quickly------ of course, some of them slipped and slid and deviated, and even the boats dozens of paces away could not be touched.

But there are always successful ------- who glide correctly, plunge headlong into the boat, and in a short time blow it to pieces!

This alarmed the great leader Kublai Khan, who sent someone to ask: "Can all the sea ships begging pirates be burned?" ”

When it came to the Liuqiu pirates, Guo Shoujing, who knew the Taishi Academy, showed hatred, but shook his head and said: "No, the sea is huge------ this thing can be used on the surface of the lake, at most the river!" ”

His reply was pragmatic, for he had tried, and even a foot of wave would have swept away the plank.

Kublai Khan, the big boss, ignored him anymore------ middle-aged science and engineering man Guo Shoujing also missed an opportunity to improve.

But he didn't realize that this was an opportunity------, and he was still developing his design.

When he heard that the Liuqiu pirates actually had weapons that exploded underground------- he thought about it for a long time, and suddenly remembered that it was just burying grenades and bullets in the ground, but the weapons were several times larger than grenades and bullets, and they were buried in the ground, and they didn't need to be thrown by manpower anyway!

Science and engineering men often think of it and have to do it with their own hands, he tried it out a few times, and sure enough, it was made!

Originally, he also wanted to develop a type that could automatically explode as soon as a man stepped on it, so that there would be no need for an ambush person to pull the rope------- but Lord Xu Heng personally came to him to introduce him to the same Hanchen talent.

He originally wanted not to participate in the dispute between Han Chen and the Hui ministers, but he was attracted by Lord Xu Heng's personal promise that all the weapons he had developed might be usable------- by then.

Therefore, Guo Shoujing, the secretary of the Tongzhi Taishi Academy, finally met the deputy general Zhang Hongfan, and after the two talked a few words, they immediately introduced each other as confidants.

However, their acquaintance was not the focus of this gathering.

The Hanchen were talking about adding points to themselves in the operation to suppress the bandits in the southern part of the Central Plains, and those beggars sent by the big families let them see the opportunity!

How to persuade the big boss Kublai Khan to allow troops to be sent, this is not difficult, they can conscript the militia!

Speaking of militias, a word must be inserted here.

The militia organization played an important role during the confrontation between the Great Song and the Great Yuan.

Let's talk about the militia system of the Great Song Dynasty first.

The role of the Great Song Dynasty in recruiting militia was to mobilize the entire population as a tool to fight the Tatar bandits.

Therefore, the militia organization of the Great Song Dynasty is a kind of organization that arms the people.

Previously, due to the reality of the military threat, the Great Song Dynasty had built a number of local militia armies in almost every administrative region, exterminating bandits in peacetime to maintain law and order, and supporting the front line in wartime------- and there was no longer an era in which the militia system was more important than the Great Song Dynasty in the entire period.

Judging from the history that has not yet happened, in the later period of the fall of Xiangyang, due to the destruction of the regular army, the militia almost became the main army to resist the Tatar bandits, such as Zhang Shun, Zhang Gui brothers broke through the encirclement of the Tatar bandits, and rescuing Xiangyang was the main merit of the militia organization.

At the same time, due to the existence of militia organizations, there were basically no large-scale peasant uprisings in the entire Great Song Dynasty, and militias also participated in several other large-scale battles.

However, they are also different from the box soldiers, the Great Song Dynasty government does not issue their military funds, everything must be provided by themselves------ of course, if there is a certain war need, there will still be some material rewards.

The Han people in the north also have a militia organization, and they have been there since the Dajin period, but it is at the level of a family member belonging to a large family, just to take care of the family------- there are few people, and it completely depends on the strength of the family.

Back then, Zhang Hongfan's father was a Tatar bandit group with thousands of his own families.

In fact, like the Great Jin Dynasty, the Great Yuan Dynasty did not like the big families to have their own armed organizations------- they were different from the Great Song Dynasty, the attitude of support, but not support, they were completely suppressed!

For example, as mentioned above, it is stipulated that only ten households and twenty households can have a kitchen knife, which is mainly to suppress the strength of large families.

Therefore, the big families in the north try their best to make their families small and fine, and basically belong to the good sticks that know how to handle one hand!

In fact, the Great Song Dynasty also banned weapons, but it was only for people who were not allowed to carry them at will when they were in social mobility; Dajin Dayuan's forbidden weapons are forbidden to the bones, and they are the basic national policy that has always been implemented.

The two militias cannot be confused.

Lord Xu Heng knows this very well.

Eventually, after discussing with the Hanchens, he began his own persuasion plan.

First of all, he was looking for the crown prince Zhenjin.

Prince Zhenjin is no longer a teenager at this time, and he still respects his teacher Xu Heng.

Xu Heng hopes to be recruited by the prince himself.

The first is that the bandits, different from the pirates, should be a rabble, and when the army arrives, it will be successful.

The second is that the crown prince Zhenjin is inclined to Hanchen, and hates the Hui ministers, especially Pingzhang Ahma, so this military feat will definitely increase the weight of the prince Zhenjin in the heart of the big leader Kublai Khan.

The third is to take this opportunity to integrate the power of Hanchen, borrow the militia of the big families and clans, rely on the prince's real gold------- and when the prince ascends to the throne, he will definitely be able to expel those lustful people from the Dayuan court!

The Hanchens' abacus was extremely fine------13110
