Chapter 38 Cannon

After leaving for another hour, Fang Yiai couldn't help it and pointed at the object and asked, "Your Highness, I'm sorry, I'm too polite. What exactly is the back of this car? It's so heavy?"

However, the food truck he was riding in was different from other cars. It only had a few bags of food and grass on it, and the weight was very light. Even if he and Du He added, it was only more than 200 kilograms. However, such a light car was heavier than the other cars that escorted hundreds of kilograms of food and grass while walking. The only thing that dragged the speed of the car was that was that weird thing.

It turns out that although the car is not equipped with many, there is a strange thing behind it. It looks black and should be cast from steel. It has two wheels under it and a long pipe in front, which is thicker than the thighs and looks like a big chimney. Judging from the rut marks on the ground, it is half a foot deep, so it is no wonder that it cannot walk fast.

"This thing is not simple. It is called cannon, nicknamed the God of War. As for power, you will know when you go to the battlefield." Li Zhen kept it a secret and did not introduce it in detail. It is impossible for the introduction of cannon to be convincing. If you want to take a walk on the battlefield, they will know it when they are.

Speaking of which, this cannon is not simple. It is a breech gun and a rifled cannon, which is much more advanced than the early front-mounted smoothbore cannon. Li Zhen also spent a lot of effort to finally get one.

In fact, this kind of cannon is not very troublesome in design. Li Zhen is a top student in science and engineering. Although he cannot design the most advanced cannon, there is no problem with the breech guns in the late 19th century.

There was only one thing that bothered him from the beginning to the end, that was the material. Although Li Zhen had already had a blast furnace and successfully refined steel, the steel made from the blast furnace was just ordinary crude steel. It was okay to make some good weapons, but it would definitely not work for making cannons.

More advanced alloy steels are not impossible to be refined. The question is whether there are other elements at this time? At this time, even aluminum cannot be refined, let alone tungsten, manganese, vanadium, titanium, zinc. At this time, the metals are generally only gold, silver, copper, iron, tin, and lead. Among them, lead and mercury are mainly provided for Taoist priests to make alchemy. Who would use it in general?

This is why Li Zhen was too focused on mechanical design in his previous life and was not very proficient in materials science. In fact, it is not his fault. In the later years, society was so developed, and each person had different divisions of labor. Those who study machinery only need to memorize the properties of various materials. Who would specifically learn how these materials were smelted?

So Li Zhen only knows a little bit of steel smelting, and is not very proficient in the later process of steel. He is still an old craftsman who sees the cannons he always explodes, so he suggests that he do some heat treatment processes, such as quenching, etc.

Only then did Li Zhen remember that steel is not just smelting, but later heat treatment is the key to increasing material strength.

However, Li Zhen was not very clear about the post-processing. He only knew that heat treatment was roughly divided into normalized annealing, back-tempering, etc. As for how to make qualified cannon steel, he didn't know.

After handing over what he knew to the craftsmen, Li Zhen ignored it. He thought that the craftsmen might take several years to make qualified steel. Who knew that just ten days before Li Zhen set out, Qianchaifang (the name of the steel workshop run by Li Zhen himself) came to tell Li Zhen that he had actually refined qualified steel.

Li Zhen was very excited and rewarded the craftsmen with great rewards, and then began to cast cannons. Because the accessories had been made long ago, even the molds in important parts such as the blasting bolts and barrels were made with the loss of wax method, waiting for the steel. So after the steel was passed, Li Zhen successfully assembled the cannons together and gave a majestic name - Thor One.

Unfortunately, Li Zhen had just built the cannons, and it was time for him to go to war. He didn't even give him the time to test the cannons. Li Zhen, who was worried, had to bring the cannons with him, and he directly tested the performance of the cannons on the battlefield.

However, I think the performance should not be too bad. When designing, Li Zhen drew on the design of many classic famous cannons in later generations and added his own understanding. Even if the cannons were in one battle, the ones they made were enough, and now they were worried about whether the materials were good or not.

There is also security, which is what Li Zhen is most worried about. However, when facing his friends, Li Zhen would not admit defeat and directly gave the cannon the title of God of War.

"The God of War? Is it so exaggerated?" Fang Yiai didn't believe it, and Du He and Xue Rengui didn't believe it very much.

"Yes, if an object can be called the God of War, then what should our General Manager Li be called?" Du He still respects Li Jing very much. In his heart, only Li Jing is worthy of being called the God of War. What qualifications does an object have?

Li Zhen was unwilling to say too much: "Don't believe it. This cannon is a magical artifact that can dominate future wars. It's not an exaggeration to call it the God of War. Forget it, just telling you that it's incomprehensible. Then you'll know it when you show it to you on the battlefield. Not to mention this, there's still some time left before Jinyang, so I'll sleep for a while."

"It's a pity." After saying this, Li Zhen closed the window.

"Oh, getting out the four-wheeled carriage is indeed the greatest invention of my arrival in the Tang Dynasty. I'll give myself a thumbs up." Lying on the sofa, Li Zhen stretched comfortably and gave himself a thumbs up happily.

The specifications of Li Zhen's carriage are the same as those of Li Shimin and Changsun (Since Li Shimin got a new car, Changsun also took away one from Li Zhen, followed by Concubine Yan, and then Li Yuan...). The carvings are the same, but they are slightly smaller, and the carvings are different, and the rest are the same.

This four-wheeled carriage is good. Not only is it stable far more than the second wheel, but it also has a huge space. With its own figure, even somersaults are enough. The interior of the carriage is gorgeous. Not only does it have a whole set of sofas, but it also has a separate small bed, and a separate bathroom is designed.

There are two mezzanines on the wall of the carriage. The outermost mezzanine is placed in steel plates, so although the carriage is made of wooden, its defense ability is actually not bad at all. The second mezzanine is hollow. Ice can be placed in summer to cool down, and in winter it can be changed to a fireplace to keep warm. This is simply an ancient version of the RV. In fact, Li Zhen designed his own carriage according to the functions of later generations.

Lying on the sofa, Li Zhen slept beautifully in a fox fur. When he woke up, the sun was about to set, and the team had already arrived outside Jinyang City. Officials of all sizes and big and small have been waiting for a long time.

After meeting a few officials casually, greeting them for a few words, and having another reception banquet, Li Zhen moved into the Jinyang Palace (Li Zhen is a prince and is qualified to live in the palace, as long as she does not live in the main hall).
