The production of grenades is not complicated, divided into two parts: flammable materials and ignition devices, the main core technology is ignition delay technology, for Zhao Zheng, who has drawings, manpower and material resources, it is not difficult to make simple grenades, the only disadvantage is the power and ignition rate, ** power or can not be compared with the smokeless gunpowder of later generations, but it is enough for this era, as for the ignition rate, at the beginning of the 20th century, it has not yet reached 100%, and the ignition rate of seventy percent in this era is already acceptable.

In addition to grenades, Zhao Zheng also made two artillery pieces, which were about the same power as the red-coated cannons of the Qing Dynasty. In fact, it is a large arquebus, the principle is the same, it is very troublesome to load, and there is no crosshair at all, but it is very powerful.

Artillery has appeared in the Ming Dynasty, and used in the Liaodong battlefield, the main technology is still in the barrel, for the craftsmen who have a certain amount of technical accumulation and experience, it is not easy to exceed the steelmaking level of the Ming Dynasty. These two cannons are models built by the top craftsmen in the country in the glass workshop, and they were pulled by Zhao Zheng to fight.

Although the firing range of these two guns reached seven miles, the cannon body was relatively heavy, with thousands of catties, which was only convenient for attacking and defending the city, and was not conducive to field warfare.

Of course, these two artillery pieces will not play a decisive role in this war, what Zhao Zheng needs is to give the officers and soldiers of the two Huai the impression of artillery might, and then they will exert pressure on the imperial court to speed up the development of artillery and firearms.

After this thing was demonstrated to San Zhao, the three of them were suddenly shocked, with this sharp weapon, it is possible to recover Shenzhou.

After handing over everything, except for Zhao Zheng occasionally going to the military camp to guide the operation, there was basically nothing to do with Zhao Zheng in Yangzhou, but Zhao Zheng did not sit idle.

Every day, the agricultural officials are told how to breed hybrid crops, which is as simple as planting three crops that need to be hybridized in one place at the same time, and pollinating them by insects or natural wind. If you want to explain the principle clearly, Zhao Zheng is a little dizzy, there are too many disciplines involved, and it will also be cutting-edge technology in later generations.

Sometimes when he encounters one or two agricultural officials with a strong desire for knowledge, Zhao Zheng is a little overwhelmed by the posture of breaking the casserole and asking the end, in order to maintain the image of a master, Zhao Zheng has to irresponsibly throw a few books to them.

It is a book compiled by Zhao Zheng from his hand and then deleted a large amount of sensitive information, which is of course written in vernacular for easy reading.

The national teacher gave the book from heaven, of course the agricultural official was ecstatic, although it was all white characters, but some places were still a little jerky, I don't know why, when I asked Zhao Zheng, Zhao Zheng asked him to understand by himself, no way, it involves the explanation of gene chromosomes, how do you let Zhao Zheng explain. At the end, I did not forget to remind them that they needed to return the original after the transcription of the agricultural book.

Gao Linmen didn't know that he had gone to that kiln to cause trouble, Yan Tianwu was in a state of retreat and cultivation, and Erlang ran to the barracks all day long to watch the soldiers practice like a day. So although the entire Yangzhou City was nervously preparing for the war, Zhao Zheng seemed to have nothing to do, sitting in his yard watching the sunset, and when he was extremely bored, he had to pull up Chengdao to help him copy books.

I read it in the back room, and Chengdao and several other Taoist priests in the Taoist temple were responsible for transcribing it.

Outside the city of Yangzhou, Li Quan looked at the thousand-year-old city in front of him, his heart was surging, and he had finally come to this point, seventeen years, he had changed from a poor boy who was not literate and no one cared about him to a big force between the Song, Jin and Mongolia, and no one in the world dared to underestimate him.

In his hand is an iron spear made by his beloved wife. There are beauties, how can the country be lacking?

Yang Miaozhen was standing beside him, at this moment Li Quan only had Yangzhou in his eyes, and she only had her husband in her eyes.

"Remember the first iron gun I made for you?" Yang Miaozhen's tone was indifferent, he was not infected by Li Quan's ambition, although Li Quan gathered hundreds of thousands of people this time, he was actually isolated and desperate.

Hearing Yang Miaozhen's words, Li Quan thought that he was complaining that he had destroyed many iron guns made by her own hands in the battlefield over the years, so he put Yang Miaozhen into his arms and comforted: "Of course I remember, I remember all the affection of the lady in my heart." ”

Yang Miaozhen sighed secretly, just as Li Quan couldn't remember how many iron guns he had used, he had also forgotten how much of his original intention.

Husband, do you still remember why you didn't want to be the Shunmin of the Jin Kingdom back then, and rose up to resist, against this disgusting God! Since ancient times, there have been many heroes in Shandong, what a heroic boy he was when he avenged his mother and brother and killed the thief, but now he has become a cold and cruel hero, do you know all this?

Yang Miaozhen looked at Li Quan's knife-like face, and her heart turned a thousand times, and she didn't say these words after all.

"The king, aunt, but you are troubled by this thousand-year-old city?" Li Quan's military advisor Zong Xiongwu lupine scarf, with bamboo in his chest, talked eloquently.

This Xiongwu is one of the few scholars who have taken refuge in Li Quan, so he naturally has Li Quan's attention, although he is only a showman, but the whole army does not dare to despise it.

At that time, Zhang Yuanbu, the first strategist of Western Xia, was also the first scholar of the Song State, but the Han Qi people killed in Haoshuichuan turned on their backs, and more than 10,000 field elites were slaughtered, which directly led to the Song State changing from a strategic offensive to a defensive position.

When Li Quan heard Zong Xiongwu's words, he became interested: "Does the military advisor have a good strategy to break the enemy?" ”

"Although Yangzhou is a Xiongcheng, but the center of the two Huai is located, it needs to be supplied around, so the money and grain are almost borrowed from the nearby states and counties, our army only needs to be surrounded for a long time, and Yangzhou is self-defeating!"

Li Quan listened to Zong Xiongwu's words and immediately felt that the situation was beginning to become clearer, but Yang Miaozhen said coldly: "After a long-term siege, wouldn't you sit back and wait for the enemy's reinforcements to come!" ”

After hearing this, Li Quan also felt that this was the case, although Yang Miaozhen was short in strategy, he was careful and could always check and fill in the gaps.

Zong Xiongwu laughed: "My aunt only knows one of them but doesn't know the other, we are besieging Yangzhou, and we also have strong reinforcements." ”

Li Quan also understood the meaning at this time: "But our family's history is the same thing? After speaking, Li Quan and Zong Xiongwu looked at each other and smiled, and they completely figured out Shi Miyuan's context. I'm afraid that by now, Shi Xianggong still has the heart of Zhao'an, and will pull the reinforcements for them.

"Come on, go to Lin'an, and say that I, Li Quan, sent troops this time because of the lack of food in the army, as long as the court meets my requirements, I will withdraw immediately!"

Li Quan was conceited that he was dragging his knife and playing beautifully, and he had to drag Song Guo to death.

"Husband, that's a hot air balloon, our army also captured one in Taizhou, and there are two clairvoyant mirrors, you can also learn from the Song army and probe the enemy's reality on the hot air balloon!"

There is a hot air balloon floating at each gate on the city wall of Yangzhou to observe the enemy's situation.

But after Li Quan knew that this hot air balloon was refined by the demon Dao of the Song Kingdom, he refused to use anything, thinking of the last time he died for no reason, Li Quan's teeth itched with hatred, and he refused to use the hot air balloon: "No!" This thing is refined by the demon way, in case there is any secret door, we will not throw ourselves into the net! ”

Yang Miaozhen went to Lin'an, and saw that the merchants were looking for production and use, and understood the principle of this thing, but it was just a larger Kong Ming lantern, and there was no magic, so he immediately said: "You can find a warrior in the army to go up, in case of an accident, you can be appeased with a lot of money!" With this sharp weapon in hand, Yangzhou's military defense can be seen at a glance. ”

Zong Xiongwu also immediately said: "King, aunt's words can be tried." ”

Li Quan saw that Zong Xiongwu also had such an attitude, so he allowed it.

But just as Li Quan's hot air balloon was raised, a stone from outside the sky fell into the army and immediately exploded.

In ancient times, warfare paid attention to formations, and infantry gathered together to form power, so the troop arrangement was very dense. It is precisely because of this that bombs flying from outside the sky can kill dozens of people in an instant.

Li Quan's army was six miles away from Yangzhou, and trebuchets could not throw stones so far, and then there was another loud bang, and more than a dozen people were killed.

The army immediately began to panic, and at the same time, the scouts in front fired signal flares, the gates of Yangzhou were opened, and a cavalry went out of the city, and the dragon and tiger roared.

"Archers come forward, pikemen prepare!" Li Quan was also a little flustered when he saw that the enemy took the initiative to attack, coupled with the unknown sound just now, but after many years of marching career, he made a quick decision.

"The shield hand is on standby! Hou Hu and Xue Wei each led a battalion of cavalry to outflank them on the left and right, and they must disrupt the enemy's position! ”

――

"Senator Zhao, General Hu, Xiaodao has a reluctant request! I, the guards who also practice martial arts, also know the truth of protecting the family and defending the country, so please take them out of the city with the senator to kill the enemy and protect the people! ”

Zhao Kui was the chief officer in charge of the raid, but the leader was led by a battle-hardened military general Hu Xian. Zhao Zheng's escort team was well-equipped, even the horses were armored, and they were real heavy cavalry, so they naturally couldn't ask for it. But I was a little worried that the escort team was a group of young master soldiers, and I heard that these guards could not live in the barracks, but lived in an inn, and they were served with good fish and meat. This weak combat strength is secondary, and if you don't listen to orders and delay military aircraft, it will be difficult to do.

Therefore, Zhao Kui gave Zhao Zheng a preventive injection in advance: "The national teacher can have such a belly, and the lower officials naturally can't ask for it, but the army has its own law, I'm afraid there will be some offense!" ”

"They're soldiers! It is their duty to obey orders! Senator Zhao and General Hu don't have any concerns! Zhao Zheng's face was solemn, and it was time to test the true combat power of his guard.

"Report! Li Quan's army is approaching, six miles away from Yangzhou! ”

"Wait! Let's talk about it close to five miles! How is the artillery loaded? Zhao Kui asked, although he is a civilian official, the heroic spirit on his body can deter the whole army, and it was Zhao Kui who beheaded Li Quan in history.

On the city wall, Zhao Kun observed the enemy situation with his glasses in his hand, and there was no distraction in his heart, even if the national teacher was beside him on the spot!

"Report! The other side seems to be preparing to raise the hot air balloon! ”

When Zhao Kui heard this, he waved his hand, not allowing the enemy army to see the garrison dispatch in Yangzhou City.

"Hu Xian! Lead the elite to ride out of the city, kill in the direction of Shuai Qi, just sweep the formation, and kill back and forth! ”

"The last general commands!"

"Wang Jian, you led the crossbowmen out of the city with the army to cover Hu Xian's retreat. This sortie is only to disturb the other party's arrangement of hot air balloons, and you can't fight! ”

"The last general commands!"

……

Outside Yangzhou City, five hundred elite horsemen rode out of the city, and Zhao Zheng's escort team rushed to the front, and their armor was the best, which meant that they needed to block the opponent's arrows first.

The effective killing distance of an arrow is 150 meters, and a good horse can run in just ten breaths. And Zhao Zheng's guards wore plate armor, which was much stronger than the armor and chain mail commonly used in the Song Dynasty, and it was impossible for arrows to penetrate the plate armor fifty meters away.

And the killing distance of the guns in their hands is 100 meters.

The iron riding mountain is coming with a tsunami.

"Get on the bayonet!"

The convoy uniformly loaded the guns with bayonets.

Just as the stirrup changed the cavalry, the bayonet is a gadget that will change the world forever!
