Great Ming National Teacher

Li Yunya's education is only at the level of junior high school. Although he is a top student, he has been the first in the township, but he only has the most basic level of chemistry. In addition to the knowledge he learned in books, he learned a little bit from some time-travel novels. , of course, and when he was a keyboard man, in order to debate with people, he specially checked some information.

The power of black powder is relatively limited. Of course, this is only compared with explosives. The Taiping Heavenly Kingdom relied on this thing to attack the city all the way, from Guangxi to Nanjing.

However, guns using black powder are very bulky, their power is limited, and the smoke is billowing, and a hundred guns firing together will soon cause a lot of smog... In Li Yunya's mail bag, there is a gift from Zhao Tiezhu, a big ginseng master in Xiaoerling His son who was in junior high school bought three test boxes. Among them, the chemical test box contains a balance scale, iron stand, beaker, measuring cylinder, test tube, crucible, etc. A full set of experimental equipment, the seller also provided gloves, filter paper, goggles , PH test strips, these small gadgets that consume a lot.

Li Yunya has been working hard to improve the formula of gunpowder since the establishment of the arsenal. First, he adjusted the proportion of the formula through trial and error, and then processed the gunpowder into granular gunpowder.

Li Yunya made sulfuric acid with green alum, nitric acid with saltpeter, and finally made smokeless gunpowder. Because the production process was complicated and dangerous, the output was very low. Li Yunya used smokeless gunpowder and black powder together to make the caliber of guns It is getting smaller and lighter, and the bullets are transitioning from fixed gunpowder to full metal casing.

After seeing the miraculous chemical experiment, the three academicians of the Academia Sinica regarded it as the alchemy of the heavens, and they were all obsessed with it. Sun Yuanhua, in particular, was working day and night, forgetting to eat and sleep. This set of tools was built separately, and Sun Yuanhua and Song Yingxing locked themselves in the experiment every day, happily conducting new experiments.

Soon, they also changed into the easier-to-wear bunt half-length suit. The top and trousers were separated. , Twice to improve the production process of gunpowder, once to increase the power of gunpowder, several times almost blow up the laboratory, leaving a scar on Sun Yuanhua's face.

Now the guns produced by Li Yunya are quite powerful, and the soldiers have also undergone training at all costs and day and night to form a combat effectiveness beyond the army of this era. The artillery is used to baptize the barrage in the distance. The range of the artillery is longer than that of the bow. The Eight Banners Army was unable to fire arrows on a large scale and suppressed the city with firepower, and those who rushed close used muskets and grenades.

Li Yunya saw a bunch of white flags waving, and a group of people were embracing them. He asked the leader of the fifth regiment: "Can you bomb that place for me!" The fifth regiment is the artillery regiment, and the leader is Qu Zhi Ming, he has a flexible mind, is quick to accept new things, and is especially good at shooting guns. He is honest and convincing, so Li Yunya made him the team leader.

According to the usual drill method, Qu Zhiming took a visual inspection first, then went to the back of a cannon and took aim with the scale on it: "It should be no problem!" He stopped the five gunners and told them not to rush to fire after loading the cannonballs. , Adjust the angle first, check and correct it yourself, aim all at the white flag, and then order to fire.

"Boom!" Five cannons shot out flames at the same time, and thick and choking black smoke spewed out from behind. Although everyone was far away and the gunner was wearing a mask, his eyes still felt hot.

Seeing that the place where the white flag is located has been hit by two shells, the powerful shells directly smashed the bones and tendons of the men and horses, and the blood was bloody, followed by a violent explosion, with shrapnel flying around and steel balls shooting all over the place. Erhachi's twelfth son, Azig, the future Prince Heshuo of the Qing Dynasty, saw with his own eyes that the guard beside him was smashed into the cavity by a shell, and was blown to pieces before he could howl, his flesh and blood mixed with shrapnel and steel balls. Azig's head and face were covered, and the 24-year-old Manchurian warrior was thrown off his horse and passed out.

With the help of binoculars, Li Yunya clearly saw the opponent's coach fall, and immediately ordered the fourth regiment to fight.

The fourth regiment is cavalry, a total of more than 1000 people. Each is equipped with muskets, grenades, and sabers. Cutting, the Eight Banners soldiers who rushed under the city wall were hit by grenades and muskets again, bombarding and exploding in their ears, thick smoke enveloped the battlefield, choking and coughing, like flies in the fog, being shot indiscriminately by cavalry guns, immediately Casualties were heavy, and at this time it was reported that the coach from the rear had fallen from his horse. Niu Lu'er really died several times, and the rout soon began.

Li Yunya did not go out of the city to pursue, but transferred the fourth regiment back, began to reorganize the team, and counted casualties.

Due to the fierce artillery fire, the archers of the Eight Banners Army were always suppressed, and did not cause a large-scale suppression of bows and arrows on Chengtou. Li Yunya distributed steel helmets to each soldier. When fighting, several people protected each other in groups. One gunner had two shieldmen to help cover, so after the battle, no one was killed, only 16 people were injured in different situations, some were shot by the stragglers outside the city, and some were injured when carrying the shells. He hit his foot in a panic.

The reason why Li Yunya didn't go out of the city to pursue the attack was because he had too few soldiers and horses in his hands, only a little over [-] at full strength, while Huang Taiji had more than [-] troops, and Yuan Chonghuan refused to make a move. He didn't pay any attention to it, and continued to follow Huang Taiji to the west. There was no hope at all. If he faced the main force of the Eight Banners outside and in the open field, the Eight Banners would come to charge a few times regardless of the cost. He worked hard to form it. This cross-age army is sure to be wiped out, and we must look for opportunities.

Li Yunya sent a scout company to the north to keep a close eye on Huang Taiji's movements. In the city, all soldiers were required to maintain a first-level readiness state and be ready to attack at any time. Everyone checked their weapons, every gun, every cannon, Every part must be confirmed intact, and an unprecedented dignified atmosphere enveloped the entire military academy city.

At the end of November, here is the lunar calendar, it is about to enter the twelfth lunar month, the sky is freezing, Huang Taiji and 10,000+ people are burning, killing, looting and playing around the city of Beijing. .

Huang Taiji didn't pay attention to the army of the Ming Dynasty at all. Although Azig exploded into a bloody man in front of a strange military academy city in the southern suburbs and lost more than 5000 Manchu and Mongolian warriors, the opponent could only rely on the city wall to defend passively. , Didn't you dare to chase it out afterwards?If he went back at this time, it would be considered a rewarding experience, but he still wanted to give it a try, what if he took down the capital of Daming?

The vast majority of people in the Ming Dynasty thought that he would leave after robbing enough. They never expected that he would dare to attack the high-walled Beijing city, including Yuan Chonghuan. Immediately a little flustered.

Huang Taiji divided the army into two parts. He personally led [-] of the most elite Eight Banners soldiers to storm Deshengmen in the north of the city, and then let Sanbeile Mang Gurtai lead Dorgon, Duoduo and others to lead [-] elite soldiers to attack Guangxi from the east. Qumen.

On the side of the Ming army, Yuan Chonghuan guarded the Guangqu Gate, and Man Gui led the army to guard the Desheng Gate. After the battle started, the fierce and tall Manchurian warriors, full of gold, silver and beauties, were completely mad, but they all rushed towards the city of Beijing. The Ming army resisted fiercely. They were the most elite troops of the Ming Dynasty at this time. At this time, they leaned against the city wall and fought bloody battles with these alien barbarians under the cover of the red cannons on the top of the city.

Yuan Chonghuan's Guan Ning cavalry is not weaker than the Guan Ning cavalry of the Eight Banners soldiers!It's just that the number is far smaller than that of the Eight Banners Army. They wield steel knives and spears in the bitter cold wind. When the knife saw blood, the spear pierced into the flesh. The blood stained the snow that had accumulated on the ground a few days ago. It will freeze and condense into bright red blood.

The two sides fought fiercely for a long time. Seeing that they could not attack, the Eight Banners Army finally began to retreat. He was not injured, because he was wearing four layers of heavy armor, and his personal guards also parried several fatal attacks for him.

But Man Gui was not so lucky. He was accidentally bombed by the gunner on the city wall and was almost killed.

Man Gui and Yuan Chonghuan had been at odds for a long time, and even because of Yuan Chonghuan, he was transferred to Shanhaiguan and left the front line of Liaodong. In the civil society, Du compiled that Yuan Chonghuan fired the cannon himself, how to ignite the fire, how to aim, and how to kill Man Gui. Huang Taiji colluded, especially those whose homes were destroyed in the Gyeonggi area.

That afternoon, Zhu Youjian asked Yuan Chonghuan to enter the city, and Man Gui and Zu Dashou also entered the city at the same time.

At this time, Zhu Youjian had already confirmed that Yuan Chonghuan was not available. You told me that Liaodong could be settled in five years. The military affairs in Denglai and Tianjin give you Shangfang sword... How did you repay me in the end?In Liaodong for such a long time, the biggest thing I did was to kill Mao Wenlong who was holding Jiannu in the rear, and put Huang Taiji into the pass for me. Now that you are asked to retreat from the enemy, you just follow him around in circles .

Now many people suspect that Yuan Chonghuan is collaborating with the enemy and betraying the country, and cooperates with Huang Taiji to take Beijing City together. Zhu Youjian is half-believed. This time, Yuan Chonghuan is called to enter the city to test it out. Yuan Chonghuan can come to prove the possibility of his collaborating with the enemy. Sex is small, do not immediately remove him.

Zhu Youjian suppressed his anger in his chest, took off his cloak, and put it on Yuan Chonghuan's body. There was not a word of reproach in his words, except for encouragement.

Yuan Chonghuan was flattered, but Wen Tiren saw the emperor's intentions. When Zhu Youjian wanted to kill Wei Zhongxian, he also kept appointing officials to the eunuchs, and even gave him the iron scroll to avoid death.

Yuan Chonghuan opened his mouth to fool Zhu Youjian, saying that Huang Taiji had brought all the elites of the Eight Banners of Manchuria and Mongolia with him this time, in order to bring down the city of Beijing in one fell swoop and rob half of the Ming Dynasty. There were a lot of them, and finally he proposed to Zhu Youjian that he had soldiers to go into Beijing to repair and defend against the enemy.

According to the regulations, the frontier troops are not allowed to repair under the city of Beijing without orders, let alone entering the city. Zhu Youjian naturally forbade it.Is he really teaming up with Huang Taiji to take over me?

Zhu Youjian's answer was only two words: "No!"
