After experimenting with naval guns, Tong Yu tested field guns and city defense guns separately. Compared with the ultra-long range of naval guns, the range of field guns is much shorter, only three or four miles, which is also the requirement of field guns. Because it aims to destroy the enemy's vitality, the target of the attack is naturally within the range of vision.

??The range of the siege cannon is between the two, but its power is much greater. It is a good choice to install on the city gate or use it to attack the city.

?? "Your Highness, are you still satisfied with these three cannons?" Tong Yu asked Li Yin a little nervously after the test firing was over.

??Li Yin nodded approvingly, because Tong Yu has directly surpassed the most basic artillery, but raised the level of artillery to the rear-loading gun, "Good job, how did you think of the rear-loading ammunition now?"

Receiving Li Yin's approval, Tong Yu's eyes narrowed into a smile, and he said: "I decided to develop the aftermarket gun after discussing it with Guo Xianyuan, and the information provided by His Highness also included information about rear-mounted artillery. His Highness bought it. The advanced machine tool can produce the parts of the rear-mounted artillery, so I put my mind on the rear-mounted artillery, otherwise it would not have taken so long to get the artillery model out.”

Li Yin walked up to the cannon and picked up a cannonball from the wooden box next to the cannon. The top of the cannonball was a round solid bullet, and the bottom was a cylindrical shell shell. Although it was ugly, it was similar to the modern Li Yin asked: "You also invented this cannonball."

"Yes, Your Highness, this is made according to the principle of the percussion gun. I thought that since the percussion gun can be fired directly, why can't the artillery not? So I made the cannonball according to the bullet of the percussion gun, but the effect of paper is not good. Well, I replaced it with a copper shell later, and I didn't expect it to be successful." When Tong Yu said this, there was a hint of luck in Tong Yu's tone.

??Li Yin asked the craftsman to open the breech bolt. He took a look, and there was indeed a firing device inside. Although it was such a simple structure, it would greatly increase the loading speed of the artillery. And the cap inside the cannonball is also a necessary condition for firing. Generally speaking, Guo Xianyuan has half of the credit for this. The cap was discovered when he was refining alchemy.

Generally speaking, Li Yin is very appreciative of the three types of artillery developed by Tong Yu. It is a pity that the shells are all solid shells, not blooming shells, but the blooming shells need fuze technology. This high-end technology is based on Taoyuan’s The technical level cannot be developed for the time being, but this has already made Li Yin very satisfied. One cannot be too greedy.

?? Patting Tong Yu on the shoulder, Li Yin smiled and said to him: "In the future, you will be the first person in the history of artillery in the Tang Dynasty."

??Hearing this, Tong Yu immediately became excited. It is everyone's dream to be famous in history. But today he finally realized it, he is no longer a useless person who only knows how to do tricks and tricks in the eyes of others.

??Qin Huaiyu and Zhu Youzhi seemed to have just woken up from the shock of the artillery. Zhu Youzhi said: "Your Highness, if the artillery is installed in the army, it will greatly improve the combat capability of the army, and it will also greatly deter the surrounding Xiaoxiao."

"Don't worry, since the artillery has been finalized, it will be produced soon. At that time, a brand new unit, the artillery, will be added to the army!" Li Yin said loudly, and the successful development of the artillery also gave Li Yin a reassurance. The emergence of this sharp weapon will greatly make up for the shortcomings of the lack of troops in Shu.

??Qin Huaiyu looked stupid. The weapon of artillery has completely exceeded his imagination. If this cannonball goes down, even if you have the ability to beat the sky, you can be beaten to pieces. The era of personal bravery will soon be a thing of the past.

??Zhu Youzhi nodded, "His Royal Highness had thought of it a long time ago. Although Youzhi also saw some descriptions of artillery. But I didn't witness it until today. It is really shocking."

??Li Yin smiled and said nothing, he turned to Tong Yu and said, "These three types of artillery are all good, let the workshop start production!"

?? "Yes, Your Highness!" Tong Yu smiled, and Li Yin's words officially marked the birth of the first generation of artillery in Datang.

After appreciating the artillery experiment, the four of Li Yin stopped by to Taoyuan. Today, Taoyuan is filled with a strong academic atmosphere. The introduction of modern teaching has made it a state of contention. Every laboratory in the research institute is busy. Some are studying the application of steam engines in production, some are developing new chemical products, and some are trying to make machinery. Different courses are offered for different people with different interests. Now it has basically been realized in Taoyuan. Li Yin is also based on Tong Yu. The requirements of Taoyuan continue to provide items needed by Taoyuan, whether it is chemical raw materials or various experimental equipment.

Passing by a chemical laboratory, Li Yin smelled a special smell. He gently opened the door and looked inside. Inside was a young man in his twenties. At this time, he was stirring a pot of meat oil. There were already many white lumps of different shapes placed on one side, which turned out to be the most primitive soap.

??Li Yin didn't bother him, closed the door gently, and said to Tong Yu: "We must encourage craftsmen to research and develop new technologies, especially the projects that I have listed as key projects. We must not slack off."

??Tong Yu walked beside Li Yin, and he said: "Yes, Your Highness, I listed the industrial equipment drawings you provided as key research projects, and gave the greatest financial and technical support."

Once the steam engine is developed, many industrial equipment that needs to be driven by the steam engine can be developed and produced. Once these equipments are developed, it will greatly increase the production capacity of Li Yin's fiefdom. This is what Li Yin focuses on. Of course, other science Technology is not left alone, it is also going on at the same time.

?? "Well, what has Guo Xianyuan been doing recently? Why haven't you seen him?" Turning around, Li Yin didn't see Guo Xianyuan, a fake Taoist, so he asked.

??Tong Yu smiled proudly: "Guo Xianyuan is competing with me! Now he is probably going to pester Ou Yewang again in the iron and steel workshop."

?? "What's going on?" Li Yin asked with interest.

Tong Yu said as he walked, "It's because of the case of the shell. He saw that my shell case was made, and he was not reconciled. He said he wanted to make the bullet like this. I said that the shell case is too small and there is no such condition. He If you don’t believe me, you will pull Ou Yewang to make bullet casings, but you have failed after several attempts.”

Li Yin has black hair, this Guo Xianyuan is really a scientific madman, but Li Yin is already very satisfied with the paper shell bullets, but it is good for Guo Xianyuan to have this idea, maybe he can really realize the manufacture of copper shell bullets .

After walking around the research institute, Li Yin went to the opposite military camp. After walking around for a long time, the three of them were a little tired, so they sat down to rest in the military office, and Zhu Youzhi frowned after leaving the artillery testing ground. At this time, he pondered for a while and said: "Your Highness, this research institute is very important, and the confidentiality of artillery and other technologies cannot be ignored. If someone else gets it, it will be extremely detrimental to His Highness and Datang. I suggest that His Highness establish An agency is used to control and prevent secret agents from stealing technology."

??Qin Huaiyu took a sip of water and said: "I agree with the words. Nowadays, Shu is changing rapidly. Tuyuhun attacked Songzhou because of Yizhou's prosperity. Maybe there will be other people plotting against Yizhou in the future, so we have to guard against it."

The fact that the two of them made such a proposal shows that they are really thinking about Li Yin. Li Yin said: "This king has already thought of it. The new household registration system is to prevent the intrusion of secret workers. The work permit and pass are also to ensure that the research institute and other places will not be suspected by some people. Unscrupulous people mix in, and no one can fake these three things, so this risk can be greatly reduced."

?? "But what if some people are bribed? For example, the ratio of gunpowder, you only need to say something verbally." Zhu Youzhi asked again.

Li Yin chuckled and said, "So, Guo Xianyuan didn't invent gunpowder. Now many Taoist priests can refine gunpowder, so there's no need to hide anything about it. Now, this king is considering reorganizing the Wuhou Pavilion."

?? "Reorganize the Wuhou Pavilion? Didn't His Highness hand over the Wuhou Pavilion to Cui Zhang?" Zhu Youzhi said.

"This is different. Cui Zhang represents the legal institution, while Wuhou Pavilion is the institution that enforces the law. The right I gave to Cui Zhang is to supervise Wuhou Pavilion to implement legal judgments, but Wuhou Pavilion still needs special people to manage it." Li said. What Yan was talking about was actually the relationship between the modern procuratorate and the Public Security Bureau.

??Zhu Youzhi nodded, "I see, how does His Highness plan to reorganize the Wuhou Pavilion?"

"Establish the Wuhou Mansion to manage all Wuhou Pavilions in Bashu in a unified manner, and at the same time set up a special security agency to monitor important personnel and arrest detailed operations." In doing this, Li Yin actually changed the shadow guard from dark to bright, and turned it into a formal organization. From now on, Su Morer will be officially in charge of investigation and counter-investigation work, and Su Morer will become a regular official, responsible for collecting all kinds of intelligence.

??With soldiers in hand, Su Morer can use the collected intelligence to swiftly deal with hidden threats, including businessmen, secret agents, officials and soldiers who have different intentions, to ensure the stability of Li Yin's ruling group.

When Li Yin said this, Zhu Youzhi and Qin Huaiyu both nodded. It seems that Li Yin is more thoughtful than they think, but Li Yin's words about monitoring important people also made them feel surprised. Does this important person include them? ?

Leaving this topic aside, Li Yin simply pretended to be the three of them and had a short meeting this time. He said to Zhu Youzhi, "By the way, you can't relax about the military affairs. All available students are assigned to various military departments. Go, set up the army's management system, take some time, let's go to the academy together, and assign these available students!"

?? "Yes, Your Highness!"

??The two responded in unison. From the various measures Li Yin successively promulgated, they faintly felt that Li Yin was strengthening his rule over the fief, and this is what a vassal should do.
