Qian Fei'er stood behind the large-caliber rifled gun, took it personally, wearing deerskin gloves on both hands, and opened the breech of the rifled gun from behind.

She shoved the cannonball into the barrel of the cannonball, picked up a slightly larger primer in one hand, and pushed it behind the cannonball.

Plugged, she closed the bomb bay in the breech and inserted a fuse in the fire hole above the barrel.

In addition to inserting the lead, there is also a slide next to it, which can cover the fire hole after lighting the lead, so that the space is sealed.

She lit the fuse, closed the slide, and pulled it on.

"Wow......!"

The sound of the fuses burning is audible even when you stand outside.

Followed by......

"Bang ——!"

The whole cannon shook violently backwards, and the two recoil-canceling brackets shook violently, and the whole cannon jumped upward, and the ground seemed to tremble violently.

The barrel of the cannon contracted violently, and a cloud of unsightly objects flew out, and a puff of smoke erupted from the mouth of the barrel.

The reason why the barrel is retracted is that Qian Feier has installed sliding air pressure pumps and brakes on both sides of the barrel, which can further reduce the recoil while preparing for the follow-up automatic shelling gun.

People always have to think about the distance and the future, and the external ignition artillery Qian Fei'er is not satisfied, she still wants to make shelled shells for electric primer fire.

"Woo......!"

There was a high-pitched and piercing sound in the air, and Qian Fei'er and Ge Long stood in place, raising their heads slightly and looking into the distance.

At great distances, the shells flew over a very long distance, and after some time, only "bangs" were heard——! There was an explosion, and a large cloud of smoke and fire exploded on the ground in the distance, and a large cloud of snow and fog exploded at the same time.

Ge Long took out a telescope from his soul guide and looked into the distance.

After reading it, he estimated the distance and was taken aback.

"Good guy, this distance, I'm afraid it's seventeen or eighteen miles, and before the enemy sees it, it's estimated that he has been blown up, Queen Mother, this cannon you made is simply too strong!"

The telescope used by Ge Long was actually made by Qian Fei'er.

Douluo Dalu has long been able to make glass, and it is simple to make concave lenses and convex lenses, Qian Fei'er only instructed craftsmen to make several different lenses, and after repeated assembly tests, they easily made a telescope.

As soon as the telescope was manufactured, Qian Fei'er used it for military use and sales, and at the same time, she had deep doubts about the so-called spiritual condensation wisdom soul bone that Tang San held.

In her mind, if Tang San was really an amazing genius and brilliant in wisdom, he wouldn't not even be able to build such a simple equipment as a telescope.

There is also artillery, you know, the first time the Tang Dynasty invented black powder, it followed closely after the development of artillery for strategic military siege.

If Tang San really had a smart mind, he would only need to think about it a little bit to understand the principle and manufacture it.

From this point of view, it is not a wisdom skull at all, but a real "essence insect on the brain" soul bone, since using it, Tang San has been on the brain all day long, obsessed with women, and has ambiguous affairs with all kinds of beauties, hmm......

Qian Fei'er was recalling, and next to her, Ge Long asked respectfully: "Your Highness?" Your Highness? ”

"Huh? Oh! What's up? ”

Qian Fei'er reacted and turned her head to ask.

Ge Long looked at it and reminded, "Queen Mother, it's time to test this armor-piercing cannon, look, can you let Weichen give it a try?" ”

Ge Long's eyes were a little fiery, this kind of military equipment had an irresistible attraction for him, or for all men.

Qian Fei'er smiled lightly and nodded.

"Yes, General Ge Long, the operation method is the same as what I did just now, remember to wear leather gloves, don't touch it directly with your hands, for fear of sweat."

"Yes, under orders!"

Ge Long responded respectfully, and then turned around excitedly to operate the small cannon that Qian Fei'er brought.

This smaller-caliber gun made by Qian Fei'er, because it is a smoothbore gun, can be loaded in both breech and breech, and it is very convenient to use one gun for two purposes.

Of course, because of the length of the barrel, if the elevation angle of the small-caliber armor-piercing gun is slightly larger, the breech loading will be very inconvenient, and in most cases, it is better to reload the breech.

What Ge Long used was to open the breech bomb bay according to the breech loading method demonstrated by Qian Fei'er in front, stuff the shell, and then stuff it into a cylindrical fixed primer, then close the gun chamber and insert a lead wire into the barrel fire hole.

Plugged in, he lit the fuse with a torch and closed the slide to seal the fire hole.

"Wow ......"

The smaller-caliber steel cannon emitted the same burning sound as Qian Fei'er's previous one, and after a moment......

"Bang ——!"

The barrel of the smaller-caliber steel cannon shrank violently, and the entire gun carriage jumped up and down violently from the ground, and then fell, and the two brackets behind supported the ground, causing the entire ground to shake violently. Courier

An invisible shadow erupted from the mouth of the barrel, followed by a thick puff of gunsmoke.

In the air, there was a burst of "woo......! After a while, only a soft sound was heard, and a large snowflake danced in the distance.

Ge Long took a telescope and looked at it, and it was estimated by visual inspection that it was also about seventeen or eighteen miles, and it was not farther than a large-caliber steel cannon.

He observed here, Qian Fei'er also had a telescope in his hand, and he also observed, and at the same time, Qian Fei'er still had some ideas in her heart.

This smaller-caliber steel cannon reduced the caliber, the shells became more elongated, but the firing range did not increase significantly, it seems, it should be the rifling.

The threads and rifling of rifled shells are perfectly closed, so that the thrust generated by the primer is fully applied to the bottom of the shell, allowing it to fly farther.

The smoothbore gun has more or less gaps and some waste of thrust, so compared with the rifled gun, the flight range can not be effectively improved even if the initial velocity is significantly increased.

Well, in addition to the need for close-range armor piercing, the barrel of future firearms must be rifled.

Qian Fei'er thought so in her heart and made a decision.

And just as she was making her decision, next to her, Ge Long sent a proposal.

Ge Long looked at Qian Fei'er and bowed respectfully.

"Queen Mother, since large-caliber high-explosive cannons and small-caliber armor-piercing cannons have been manufactured, and the rate of fire and firing cost are far less than the three-bow bed crossbow, can you directly replace the three-bow bed crossbow troops?"

Qian Fei'er also joined the three-bow bed crossbow unit by the way in the reform of the military class, and the training was specially used to snipe the enemy Title Douluo.

She heard Ge Long's suggestion, thought about it for a while, and felt right, so she nodded.

"Okay, General Ge Long, pass on my order, from now on, the Three-Bow Bed Crossbow Force will keep a part of the Three-Bow Bed Crossbow for commemorative and cultural heritage, and the rest will be dismantled and replaced with armor-piercing guns.

In addition, each infantry team is equipped with seven vehicles per 100 people, including four large-caliber guns and three small-caliber armor-piercing guns.

With the exception of the artillery operator, the rest of the men remained the same, still crossbowmen, longbowmen, and hoplites, in a four-to-three-to-three ratio. ”

When Ge Long heard this, he frowned slightly and asked suspiciously.

"Queen Mother, don't you make these firearms miniaturized? If we make these miniaturized firearms, we can greatly reduce the physical fitness requirements of soldiers, so as to obtain more soldiers, and greatly improve combat effectiveness in a short period of time. ”

Miniaturization of firearms, that is, muskets? It's not that Qian Fei'er didn't think about it.

She also thought about modifying the arquebus, making its projectile into a similar cone, rifling, and at the same time loading from the breech, and the primer gunpowder was fixed in advance for rapid fire.

However, even if the bullet fired by the musket is a conical bullet, its mass is smaller than that of the arrow, and the penetration power is reduced.

In the current Douluo Continent, whether it is heavy infantry or cavalry, they are wearing heavy plate armor with a thickness of more than one centimeter.

This kind of plate armor, relying solely on the penetrating power of bullets, is difficult to cause effective damage at a distance of 450 meters, and only a divine arm crossbow can hurt its life.

So she shook her head.

"No, Marshal Goron, it remains the same, these small firearms are difficult to effectively kill heavily armored targets at long distances, and we still need the Divine Arm Crossbow, the Yew Longbow, and the Recurve Compound Bow."

When Ge Long heard it, he bowed respectfully and responded.

"Yes, follow the Queen's orders."

After that, Qian Fei'er ordered Ge Long to manufacture and install two kinds of artillery on a large scale, and then returned to the harem of the Heaven Dou Palace, Xuelin Palace.

Back in the Xue Lin Palace, Qian Fei'er entered the front hall of the main hall of her palace.

Next to the kotatsu in the front hall, there was a large circle of traversers, including Qian Linjue, Qian Na Wei, Hua Ning, Zi Jin and others.

After Qian Fei'er entered, she smiled lightly, sat upright in her place, crossed her legs, closed her eyes slightly, and began to cultivate.

Linglu, who had a dull hair on her head, saw it, blinked her eyes twice, and asked suspiciously: "Sister Fei'er, why do you cultivate so early, it's only morning." ”

Normally, people's cultivation is carried out at night, which can be used as a substitute for sleep, and the night time is very long and quiet, which is the best time for cultivation.

If it was usual, when Qian Fei'er heard it, she would inevitably respond to Linglu with a smile and explain the reason.

But today, she didn't do this, but still closed her eyes slightly, as if she was about to enter a state of steady.

Qian Linjue sat next to Ling Lu and found that Qian Fei'er ignored her wife, and immediately frowned.

He wanted to ask his sister Fei'er why he ignored Linglu, but he was afraid of shocking Qianfei'er, so he finally had to snort angrily, turn his face to the side, and vent his dissatisfaction in his heart.

Qian Fei'er heard the snort, and the optimistic willow eyebrows frowned slightly.

This snort, was it sent by Lin Jue, is she dissatisfied with my attitude just now?

With this thought in her heart, she opened a trace of squinting eyes, let go of her cultivation posture, turned her head to Ling Lu, and smiled lightly.

"Linglu, I have a little problem with my psychological condition, so I need to borrow cultivation to divert my attention, and I don't mean to neglect you, I'm sorry."

In fact, Ling Lu was not angry, nor did she feel that Qian Fei'er was snub to herself, but when Qian Fei'er said this, it was obviously not for Ling Lu, but for Qian Linjue.
