Qin Huaidao thought that if this matter was personally agreed by His Majesty the Emperor, it would have nothing to do with him.

Asking to see the emperor to ask about such a thing, Qin Huaidao did not have such qualifications, so he thought of Du He.

Flying Tiger Command.

When Du He saw Qin Huaidao, he asked a little curiously, "Minister Qin, why are you free to come to me today?" ”

Qin Huaidao's personality is a little dull, not sociable, and rarely goes out and about. Duhe asked.

Qin Huaidao said his intention, and Du He smiled: "This is nothing. There are more people who have seen artillery firing, and it is not a leak to let him see the artillery firing. The technology of artillery manufacturing, as well as the recipe for gunpowder, is kept secret.

You don't need to ask the emperor for this, you can arrange it. When I meet with the emperor, I will mention it by the way. ”

Qin Huaidao took the reassuring pill, let go of his thoughts, and told Qin Huaiyu when he went back.

Qin Huaiyu couldn't wait to find Harold, and said happily: "Big brother, my brother agreed, and it will be arranged in a few days." ”

In order to train artillery backbones, there is an artillery officer training team under the department.

On this day, the artillery training team conducted live-fire training. Harold and others were arranged to visit.

At the shooting range, the officers and soldiers of the Tang Army launched six Shenwei cannons, each cannon was operated by nine soldiers, each soldier had his own responsibilities and positions, and the soldiers operated in an orderly manner with the password.

When the soldiers were ready, they reported in turn: "One is ready." "The second door is ready." ……

The artillery commander took a small red flag in his hand, waved it down, and shouted: "Fire!" ”

The soldiers lit the cannon twists at the end of the cannon, then opened their mouths and covered their ears with their hands.

"Boom!" "Boom!"

There was a deafening sound that shook the ear bones of Harold and the others, and they almost fell to the ground.

Qin Huaiyu knew that before shooting, he had to cover his ears in advance, he deliberately didn't tell Harold, he wanted to see him laugh. So, he set his sights on Harold.

Harold was engrossed, staring at the movement on the shooting range, completely ignoring Qin Huaiyu's movements, which made Qin Huaiyu a little disappointed.

The artillerymen conducted shooting training in turn, and fought for more than an hour, and Harold watched with relish and carefully observed every movement of the artillerymen.

After the live firing, Harold was invited to see the cannon.

Harold took a closer look and saw that the Shenwei cannon had a thick body, more than two meters long, and the muzzle was the size of a bowl. The barrel of the gun rests on a bracket with wheels more than a meter high on either side. There is also a hook at the back of the bracket for easy dragging.

Behind the cannon, there is a box of shells, which contains various types of shells, such as solid shells, flowering shells, and scattered shells.

Then, Harold and the others came to the target to watch the effect of the shelling.

Harold saw that the one-foot-thick plank, at a distance of several hundred meters, was shattered by the impact of solid bullets, and the flowering bullets even exploded a foot-deep crater in the ground.

The artillerymen did not fire shotshots, and Harold did not see the shooting effect, but listening to the artillerymen, the shotshots hit thousands of grains of iron sand, and hitting the infantry or cavalry was definitely a nightmare for the soldiers.

Harold imagined that he seemed to see the warriors of the Arab Empire being knocked down piece by piece!

Harold asked the officers who accompanied them how the gunpowder used to fire the shells was made. The officer said: "This villain doesn't know, we artillerymen only know how to use it, as for how the cannon and ammunition are made, we don't know." ”

Harold said regretfully: "Oh, how great the people who have mastered these secrets must be, I'm afraid there are few people in the entire Tang Dynasty who know about it." “

Qin Huaiyu said proudly: "That is, there are very few people in the entire Datang who know, and the formula of gunpowder, even those workers who make it, only know a part of it, and the people who can finally synthesize it are no more than five people in the whole Datang."

My brother is one of them. ”

Harold was very depressed when he heard it, but when he heard Qin Huaiyu's last sentence, he couldn't help but light up.

Returning to his lodgings, Harold wrote a recital to the caliph, in which he described in detail the situation of the artillery of the Don army, and was extremely shocked by the power of the artillery.

In his reply, the caliph said that he must try to fully grasp the secrets of the Tang army's artillery, and he had sent a general of the "Holy Defenders", the most elite army of the Arab Empire, to Chang'an with an elite detachment, and if necessary, to kidnap Qin Huaidao.

The Royal Bureau of Home Affairs was established on the basis of the original Li Shimin Shadow Organization, and is responsible for the investigation of domestic anti-subversion affairs.

Zhou Pan was originally the deputy head of operations in the Shadow Organization, but since he took the position of director of the Royal Home Investigation, he found that this job was too difficult and he was not very competent.

The object of the investigation of the Royal Home Affairs Investigation Bureau is mainly the activities of various major forces in the country, in fact, it is to investigate the influential figures between the government and the opposition in the domestic political situation.

Zhou Pan found that this was a chore, and if it was just a problem and then sent someone to investigate, this would be easy to do.

However, one of the major tasks of the Royal Interior Investigation Bureau is to prevent the formation of anti-government forces in the country, which requires the monitoring of important ministers and court dignitaries, and this is difficult to grasp.

The various forces in the country are intertwined and extremely complex. Zhou Pan used to work under Ma Xuanliang and was responsible for some specific things, but he was still competent.

Now that it was his turn to take charge of himself, he realized that he lacked the ability to control this important position.

On this day, Zhou Pan came to the Royal Military Academy and found Ma Xuanliang, who served as the deputy director of the martial arts teaching and research department at the Military Academy.

Zhou Pan said: "Manager Ma, junior brother, after I became the director of the Royal Home Affairs Investigation Bureau, I found that I was unable to do things, I used to follow you to do things easily, how can I do this well, please give me some advice." ”

The relationship between Ma Xuanliang and Zhou Pan has always been very good, and he knows that what Zhou Pan said is from his heart.

Ma Xuanliang said: "We are brothers, let me tell you the truth, after the new emperor comes up, you will be replaced by the governor, it is the emperor's trust in you." It was also a relief for me.

When I followed Emperor Taizong, I mastered a lot of things that were not on the table, and I also offended many people. The emperor's arrangement of this position for me to provide for my old age is the emperor's grace to me.

Otherwise, it's hard for me to have a good death.

It's a complicated matter, and if you really want to listen to my advice, it's best to quit this job and continue as deputy director.

You are an honest person, and the position of Director of Investigation must be a quick-thinking and ruthless person to be competent. Your personality doesn't quite fit. ”

Regarding Ma Xuanliang's words, Zhou Pan is still very convinced.

Back at home, Zhou Pan thought about it repeatedly and decided to resign to Li Su.

Zhou Pan was a person trusted by Li Su, and he thought that Zhou Pan's reasons were more sufficient, so he agreed with him and let him continue to serve as the deputy director of the Royal Home Office in charge of operations, with the same rank.

The most important thing for any feudal emperor is to guard against some people plotting to rebel and keep abreast of the movements of important political forces in the country, which is an important preventive measure.

Who will be the director? Li Su has never had a suitable candidate.

On this day, Li Su returned to the East Palace from work and met Wu Cong who was smiling and groaning, and she said, "Big brother, you are back." ”
