Jingwen encouraged the gunpowder technicians to try a few more times, but he didn't want them to risk it, and they had to take safety measures before they did it. Because they are all Jingwen spent several years before they were like gunpowder technicians trained by crossing the river by feeling the stones. If something goes wrong with them, it will be very difficult for the next gunpowder research, and the losses will be very huge. So Jingwen persuaded them not to take too many risks, and would rather spend more money than take risks.

And I have to say that the ability of these gunpowder technicians is quite good, and they quickly tested the new amount of medicine in a new barrel. And Jingwen is also going to start a second experiment, that is, to make a real ancient cannon. And although the flying thunder cannon just now is very powerful, the short range is a problem that has to be said. The development potential of the Flying Thunder Cannon is actually not too large, and this is actually explained by history. Although the Flying Thunder Cannon is powerful, it is only something that can be supplemented in the short term, and it will eventually return to ordinary conventional artillery.

Jingwen also has to get the conventional artillery out, after all, if everyone goes to the Flying Thunder Cannon in the future, then I'm afraid that nothing will be studied in the end. So get the conventional artillery out, and then those armorers can continue to study other artillery, so as not to get into the dead end of the flying thunder cannon.

"Master, you help me draw this blueprint, and then we can make a new type of artillery!" Jingwen said.

"Okay!" Immediately, a technician from the Armament Supervisor replied.

Next, Jingwen began to draw drawings of the new artillery. And this cannon is actually cast by the casting method, first of all, it is necessary to make a mold, and then make some materials into a cannon-like mold, and then put it into some mixed material soil, and then burn the soil to become a mold. And this mold made of clay can also pour the melted bronze water into it, and when it cools, it can be preliminarily turned into a cannon blank.

Finally, the so-called polishing of the barrel is done, and there is some other work. This kind of casting method Jingwen studied a lot when he wrote online novels in his previous life. So he knows a lot about this. These methods have actually accumulated nearly a thousand years of technology, and under normal circumstances, it takes thousands of years to be able to research, but Jingwen uses them so casually, so Jingwen is really very unkind.

These craftsmen of the Ordnance Prison are indeed worthy of mastery, and two hours after Jingwen had just finished drawing the drawings, they had made the model and were ready to start casting the cannon mold from yellow clay. And what earrings on the gun mold, as well as various things, have been left in advance, indicating that these are reserved parts. Then, after the yellow mud is dry, you can start to prepare it to be fired in the mouth of the ceramic kiln. Once the mold is fired, it can be used to cast the cannon.

"My lord, we have melted the bronze copper, and we should pour this copper water into it next, so that when it is cold, it will become a cannon." The technician said.

"Okay, let's start infusion! However, you must be careful not to go wrong! Once this copper water touches a person, it will kill a person! Jingwen still didn't forget to tell them about the issue of safe production.

"Don't worry, sir. We've been doing this for a long time, and we've been familiar with it for a long time. We won't have a problem! The technician replied.

Soon, the copper water was poured into the cannon, and when the copper water was gradually filled. Jingwen waited for it to cool down on its own. However, this process took a long time. After it cooled down, the day passed, and Jingwen could finally see if this cannon could be successful.

"Let's check if the bore of this cannon is smooth. The smoother this breech, the better. Don't be uneven, if there is a slight unevenness, then polish it smooth. If not a smooth cannon. That's very dangerous, when you go to the battlefield, it's not about killing the enemy, it's about pitting your teammates and selling your teammates! Jingwen shouted.

The technician quickly checked the smoothness of the breech again, and made sure that it was still very smooth, and Jingwen was much more relieved. As for the end, Jingwen also asked everyone to check it to see if there is any so-called trachoma, if there is, it is very easy to blow up.

And this cannon is made of bronze, so the cost is very high. The reason why Jingwen does not use steel is because it is still possible to use steel to make flying thunder cannons, but it is not good to use it to make traditional artillery. The projectile of the Flying Thunder Cannon is small and burns slowly, so it can be made from the steel of this era. Although Jingwen has figured out a way to make steel, the quality of steel is probably not as good as that of later generations of cannon steel, so don't risk using steel to make this traditional cannon.

The traditional cannon uses an instantaneous explosive force and then shoots the ammunition out, unlike the Flying Thunder Cannon, which pushes out the shells, so this is the difference. This kind of explosive artillery must be very strong, if it is not strong enough, I am afraid it is also very dangerous, in case it is blown up, it will be a pit teammate.

"My lord, we've polished it so smooth that we can use it as a mirror. But what do we do next? The technician asked.

Because the people of this era didn't know how the artillery should be cast and how to use it, they couldn't do without Jingwen's guidance, and now they all came to ask Jingwen about the production of this artillery. And when Jingwen saw this situation, he didn't have anything to do, that is, he started to make cannonballs. However, the shells of this era were still very simple, just make the steel into a ball just enough to fit into the breech, and nothing else was needed. And this kind of thing, many technicians can make zuò.

Soon, the shells were ready, and several were made, so that several shells could be fired. When Jingwen pulled the cannon again to the test site, he was ready to start testing the bronze cannon. And this bronze cannon is made by Jingwen according to a well-known artillery cannon in later generations! And this cannon can be said to have been made a high starting point by Jingwen at the beginning, so his advantage is very huge, and the development time of artillery in the future will definitely be very fast.
