The Black Armor Army was lucky and escaped the catastrophe, but Yang Wenli didn't know all this, he was developing mortar shells at this time.

He has always been like this, the grenade was developed, and he let Wang Rucheng design the mass production method, there is an essential difference between experiment and mass production, the experiment is relatively easy, but it requires rich theoretical knowledge, and mass production is very time-consuming, and you can patrol the regulations.

Even though he has a full stomach of modern scientific and technological knowledge, he is only one person after all, so he has to spend his limited time on scientific research.

Ever since he developed smokeless explosives and grenades, he has already had a great ambition in his heart, and he wants to use the knowledge he has mastered to modernize China hundreds of years earlier.

This project is very big, and he may have to devote his whole life to scientific research, but people have dreams, and only when they have dreams can they be motivated, and he believes that this is where he embodies the value of life, and it is even stronger than the temptation of reunifying China.

Although mortar shells and grenades are cast from pig iron, the difference between the two is very large, and in terms of scientific and technological content, they are not at the same level at all.

Anyone who has watched the anti-Japanese drama knows that the mortar shell is a spindle shape with a stable tail, which involves mechanics and fluid mechanics.

The reason why it is a top-heavy spindle shape is because the mortar shell is detonated by a rambling fuse, and the stumbling fuse is in the front of the warhead, and the heavy head ensures that after the shell is fired, the head always hits the ground first.

The reason is simple, but what is the ratio of head to tail? What is the size ratio of mortar shells? What shape should the rear wing take? How big should it be?

To tell the truth, let alone mortar shells, ordinary people can't even make a simple kite, and Yang Wenli had only seen mortar shells on TV in his previous life, let alone made them.

Without it, except for experiments and experiments, he doesn't know advanced mathematics, and he can't calculate them with a pen, so he can only use stupid methods.

After having a grenade, Yang Wenli directly denied the previous grenadier program, the power of the grenade is too small, similar to the grenade, although the range is a little farther, in the Ming Dynasty, this advantage is not very useful.

Yang Wenli plans to develop the 60 mortar, he has a projectile and explosives that are not weaker than the level of World War II, as long as the design is reasonable, it can also achieve an effective firing distance of several miles, and the power is several times greater than that of a grenade, which is regarded as a firepower upgrade, not repeated development.

……

In the first few months of the first year of Chongzhen, Siye was peaceful, and even Jiannu, a militant element, was busy recruiting Mongolian tribes and had no time to make trouble for the Ming army.

The rebellion within the Ming Dynasty was also temporarily extinguished, for a while, it seemed that the world was too peaceful, Emperor Chongzhen because of the execution of Wei Zhongxian's faction of the eunuchs a year ago, the government and the opposition sang praises of virtue, Emperor Chongzhen suddenly had a sense of Yao Shunyu soup, he was ambitious, wanted to make a career, hoping to be comparable to Taizu (Zhu Yuanzhang) Chengzu (Zhu Di) of the merits.

Since there is no worry about the inside and outside for the time being, Emperor Chongzhen can't help but think of the Black Armor Army, a force that does not obey the king's law.

Last year, he went to the military department and Youji to find the whereabouts of the Black Armor Army, but there was no news, as if the army of several thousand people had disappeared like this, he knew that this was impossible, no one had found it yet, hiding in a hidden place, and secretly developing.

"Cao Daban" After Chongzhen figured it out, he called Cao Huachun, who was on the left and right.

"The slave is in" Cao Huachun took the dust in his right hand, hung it on his left arm, walked to the front of Chongzhen and bowed his waist.

"Xuan Luo's nourishing majesty!" Chongzhen made an order.

"Minion Honor!" After Cao Huachun bowed again, after taking three steps back, he turned around and went out to arrange for the little eunuch to pass on the decree.

Chongzhen's study room has many military secrets, and only a limited number of confidants such as Cao Huachun, Wang Chengen and Wang Dehua can accompany them, and sometimes help Chongzhen review and fold.

At this time, Wang Chengen was still Cao Huachun's subordinate, this is the difference in the background of the two, to be honest, Wang Chengen and Chongzhen have a closer relationship, because Chongzhen was brought up by Wang Chengen.

Cao Huachun was slightly cold when he was young, he became a eunuch at the age of twelve or thirteen, he was gifted and intelligent, diligent and studious, and was greatly appreciated by the great eunuch Wang An at that time.

Later, Wang An fell, he was designated by Wei Zhongxian as Wang An's party was excluded, and was demoted to Nanjing to sit on the cold bench for seven years.

It can be seen that his ability is extraordinary, far from being comparable to Wang Chengen, so he is now the chief eunuch of the official eunuch, and Wang Chengen is only his deputy.

Jin Yiwei, just outside the imperial city, soon Luo Yangxing entered the Shang study, he bowed and said: "Minister, Jin Yiwei commanded Luo Yangxing, knock on the emperor, long live my emperor!" ”

Chongzhen, who was criticizing the folding, stopped the royal pen and opened the golden mouth and said: "Flat!" ”

"Emperor Xie!" Luo Yangxing swallowed again before getting up and standing in front of the emperor.

"Luo Aiqing, last October, Lone ordered you to send someone to lurk in the lair of the Black Armor Army, how is the progress now?" Emperor Chongzhen was a diligent king, and he didn't have time to chat, so he asked directly.

"Please forgive your majesty! To this day, the lurking little flag officer still hasn't really entered the bandits' lair, and is still working as a tenant farmer in the outer valley.

The minister listened to what he reported, the old nest of the black armor army, he was honest and tight, basically did not go out of the cottage, and did not recruit minions, so the little flag officer could not find a way to enter the cottage. ”

Although Emperor Chongzhen's words were not loud, they scared Luo Yangxing, which lasted so long, but he did not have an inch, and the king's anger was not a joke, so he immediately knelt down and begged for mercy.

Although the commander of the Jinyi Guard is beautiful in front of people, he is only a dog of the emperor, and all his power comes from the emperor.

"Really? According to what you said, the Black Armor Army has not developed its power, but it is worry-free, have you found the whereabouts of the thousands of Black Armor Army's troops? ”

When Chongzhen heard this explanation, he didn't get angry, he was afraid that the Black Armor Army would continue to grow and develop, and when he learned that the Black Armor Army was closed, he was relieved, so he asked another question about the Black Armor Army.

"I'm sorry! Wechen is not effective, and has not found the whereabouts of the Black Armor Army, since the Black Armor Army went to sea from Songjiang, it is nowhere to be found, Wechen judged that it was to Liaodong, but Liaodong and I Ming stand across the sea, and the territory is vast, Weichen is really powerless to investigate the truth, please Your Majesty to surrender! ”

At this point, Luo Yangxing does have a hard time, Liaodong is the territory of Dongjiang Town, and Mao Wenlong has become a warlord, only his ministry does not have a supervising army, not to mention, send Jinyi Guard, it is a meat bun to beat a dog, and there is no return.

It's not that they were all killed, but they couldn't pass on information at all, and that faction was the same whether they were sent or not, which Mao Wenlong managed very strictly, because there were many illegal things in Dongjiang Town, such as private trading, reselling Liaodong's life, Dongzhu, leather goods, etc., each of which was a capital crime of collaborating with the enemy, and it would be strange that he could let people pass information casually.

Chongzhen was still a little Zhengtai at this time, and his knowledge was shallow, he thought that it was really difficult to investigate across the sea, so he didn't blame Luo Yangxing, but he didn't see his work, and he was not in a good mood, so he didn't say a word, and waved his hand to let him retire.
