Chapter 130 Slap Yang Bao in the Face

It is possible that they may not see such beautiful operating skills as Xu Feng once in their lifetime.

In fact, these operations are not difficult.

Moreover, when an artist is excellent, he or she does not need a ruler at all. He or she can produce a finished product based solely on experience.

Looking back at the thousands of years of history of our motherland, there have been many skilled craftsmen and even emperors...

In fact, the most difficult part of cannon manufacturing is the barrel, which is of course one of the most important components of a cannon.

After all, after the gunpowder inside is ignited, the high heat generated by the burning gunpowder and the high-pressure airflow push it forward.

However, when the shell leaves the barrel, it will gain an initial velocity of several hundred meters per second, or even more than a thousand meters per second.

Therefore, in order to ensure the stability and integrity of the artillery shells, the traction coordination between the inside of the barrel and the rifling is very important.

In general, the most ingenious step in designing a cannon is probably to make the shell rotate inside.

In this way, the initial velocity of the impact force can be increased, and of course the opponent can be hit more accurately.

However, these are all modern knowledge. In an era like ancient times when productivity was relatively weak, it was extremely difficult to truly realize them.

Fortunately, Xu Feng's early preparations were quite sufficient, so all these important preparations were naturally completed.

When we think about the war era in modern society, although there were many traditional methods to make cannons, such as the famous Type 81 cannon, which was made of blue steel rails and steel pipes made by the simple method of sharpening scissors and kitchen knives, the lethality of this type of cannon was not very strong.

Xu Feng used the foundation of modern science, combined it with the actual productivity of ancient times, and added his own improvements to design such a perfect design plan.

Of course, most of these can only be used for emergency situations, and they will need to be improved after the initial prototype is seen.

However, Xu Feng had a long-term vision and was always thinking ahead. He had already formed plans for future improvements.

The material of the steel pipe used to manufacture cannons must meet the characteristics of being hard, pressure-resistant and high-temperature resistant.

Fortunately, the blast furnace that Xu Feng had improved before was fully capable of processing steel materials that met these characteristics.

In fact, making cannons is a complicated project, but due to the conditions in ancient times, Xu Feng omitted many tedious steps.

In a word, you just need to fire the shells safely and let them explode instantly in the enemy camp, causing certain damage.

While Xu Feng continued to operate, he kept thinking about the most advanced technology for monopolizing the manufacture of gun barrels in later generations.

"Ugh!"

He sighed heavily. If the current conditions did not allow it, he would really like to introduce this technology into ancient times.

Then Xu Feng put all the prepared parts into cold water to cool them down, and then transferred the elasticity and springs into another lock core through the pores.

"Actually, this isn't difficult. If you've heard of the Luban Lock, you'll understand the principle."

Xu Feng spoke lightly.

"Our Luban lock is a large, stable lock formed by its ingenious internal structure. The same principle can be applied to the production of cannons, which is naturally foolproof."

As soon as Xu Feng finished speaking, he immediately demonstrated it to everyone present.

"We are trying to increase the diameter of the cannon muzzle and the length of the barrel to increase the deterrent effect of the ammunition. However, due to the immaturity of current technology, any rash increase may pose certain safety risks."

Xu Feng planned to put the improvement of the cannon at a later stage.

After working for three hours, a wooden cannon model suddenly appeared in front of everyone.

"Master Xu, please stop joking. How can a piece of wood like this really do any harm?"

Yang Bao looked at Xu Feng disapprovingly.

"Have you all learned the skills the master craftsmen just taught you? Now, I'd like to trouble you all to show our Master Yang your skills."

After hearing this, everyone present came to their senses.

The operation just now was just a teaching method. If these craftsmen could make real cannons according to the process taught by Xu Feng, that would be an amazing skill.

"As ordered."

Xu Feng walked outside leisurely with Mr. Zhuge.

"Master Xu, if you don't keep an eye on it, aren't you afraid that if something unexpected happens, that guy surnamed Yang will give you trouble?"

Mr. Zhuge felt a little worried for Xu Feng.

"What's so difficult about it?"

Just now, Xu Feng obviously used the simplest method to teach, and those present were all veterans with a certain foundation, so it was easy for them to learn this skill.

As the sun gradually set, the craftsmen walked out of the room pulling a cannon.

"Master Xu, it's done."

Xu Feng turned his head and looked at the finished product. "Then why are you still standing there? Let's start the test firing now."

"As ordered."

Finally, under Xu Feng's command, the workers filled the cannon with shells, and then aimed the cannon at a sword handle made of steel in the distance.

"All of you get out of the way. I'll fire the first cannon."

Following Xu Feng's order, everyone present made way for him.

Zhao Feng walked forward calmly, slowly turned the handle of the cannon, and aimed the cannon at a more precise position.

Then he immediately pulled the trigger.

"Rumble..."

A loud bang came from the barrel of the gun, and the whole mountain shook.

"Amazing."

"Master Xu, this new weapon has never appeared in our Dashun!"

Mr. Zhuge also looked at Xu Feng in shock. He did not expect that the new weapon developed by Xu Feng would have such great destructive power.

"The lethality of this cannon is enough to instantly kill dozens of top Kailong masters."

Looking at the mountain in the distance that had already been blown to pieces, Mr. Zhuge couldn't help but sigh in his heart.

The firearms of this era are much more lethal than cold weapons.

"The cannon's caliber is 16,552 millimeters, and the shells are made of two kilograms of explosives. Its power is immense."

"With such firearms, we in Dashun will have an advantage in the future, not only against the Japanese pirates, but even against the entire world."

"Yes!"

"Master Xu is truly a blessing to us."

"..."

Xu Feng listened to the cheers coming from the crowd and looked at the shocked people around him, a slight smile appeared on the corner of his mouth.

He turned around and looked at Yang Bao, who was already stunned, with a smug look on his face.

"Master Yang, do you have anything else to say?"

Yang Bao looked at Zhao Feng in shock. His old face flushed red. He hurriedly found an excuse and turned around to leave.
