However, Bailiyan also found a problem, these guns are still smoothbore guns, no rifling, but the accuracy of the bullets has been standardized, slightly smaller than the chamber of the rifle, because it is a smoothbore gun, so the accuracy will be worse, but it will not be much worse within one or two hundred meters.

This is because the metal material has an expansion coefficient, the bullet will expand at the moment of the deflagration of the propellant, and the expanded warhead is close to the wall of the tube, so it has a certain accuracy of ejection, and the accuracy in the short and medium distances is average, but it will also weaken the kinetic energy of the projectile, so the bullets of this gun are low-velocity kinetic energy bullets. So although it is a smoothbore gun, there are also guns that only have a front sight and a U-shaped notch for aiming, but there is no ruler.

In addition, it should be fortunate that there are no problems with automated weapons, or such discharging technology, in particular. The firing pin continues to be consumed, which has a great impact on automatic shooting, and it is impossible to shoot dozens of bullets and stop and return the firing pin, so the practicality of automation is very poor.

The above is limited to firearms, and other ammunition and weapons Bailiyan surveyed one by one.

In this naval battle, the Xianguo Navy was in a weak position in both quantity and tonnage, and rapid-fire artillery and ammunition balanced the disadvantage in tonnage and quantity, so at best it was a draw, and at this time the other magic weapon of the Xian army, the "grenade", played a great role.

The armpit people found that they could not overwhelm the Xian army with the density of fire in the fire and rate of fire of the ship's guns, so they turned to hand-to-hand combat in the middle and late stages, after all, they were immortal, but what awaited them was the end of the world.

The grenades of the Xian army were thrown in large quantities from a distance of thirty meters, which can almost be described as overwhelming, and they were also equipped with white phosphorus bombs, ammonium nitrate explosives, and even TNT. As soon as you come, I will greet you, so much so that most of the armpit warships were not sunk by naval guns, but were killed purely by close combat.

Of course, when the armpit men approached, they would shoot a row of guns, but the Xian army also had small steel cannon grenade launchers, and a ship could have as few as 20 guns and as many as 30 guns, specializing in white phosphorus bombs and incendiary bombs, and it could not wait for a close 200 meters to burn the upper deck of the enemy ship beyond recognition, and at the same time cause the gunpowder on the ship to detonate, and it was completely finished. When you're choking on enough, you can release a gun, and I can release a gun.

Therefore, the key to the victory of this naval battle was not the naval artillery, but the short-range fire attack within 200 meters, and the density of the firepower of the Xian army at close range overwhelmed the armpit people, even if a ship was faced with a flank attack from both sides, it still had more than enough to deal with, just because the Xian army had a faster rate of fire and more means of individual firepower.

Throughout the afternoon, Bai Liyan carefully interrogated all the details, and focused on searching the personal belongings of the armpit people, trying to find and deduce their technical level. If there are mirrorless glass products, whether there are photos, their eating utensils, etc., you can get industrial information related to it.

What relieved Bailiyan the most was precisely the clothes they were wearing, because it was not cotton, but an unknown fiber, but not hemp, it can be determined that it is a plant fiber that is not produced in the southern hemisphere, and the yield should be very high, otherwise it is impossible to mass-produce standard quilts.

If the fabric is not and there is none, it means that it is impossible for him to make it, and of course other fibers can be used instead, but at least the shortcut process of mass cheap and mass industrial manufacturing does not exist, and it will also delay the time for them to reverse study human gunpowder.

And without it, it is impossible to synthesize smokeless safety gunpowder, because it is a military strategic material. Without safe smokeless gunpowder, no better propellants and explosives can be produced.

Of course, it may be possible, but at least it is difficult to make a breakthrough in the short term in the technical path of safe smokeless gunpowder. Moreover, the invention of all chemicals is full of accidents, if the equipment that is now commonly installed has not yet used advanced gunpowder, it is unlikely that a large number of advanced gunpowder will appear in the short term, so now the principle of ammunition and gunpowder chemical industry, human beings occupy an absolute advantage.

After dark, Bai Liyan did not continue the unfinished work, observing the armpit man's every move outside the prisoner of war camp.

The photos provided by Jiang Jie have all been seen by Bailiyan. Of the 4,729 axillary men, there were 4,127 axillary giants who were between 2.3 and 2.5 meters tall. Armpit dwarves, who have the highest IQ among axillary people, have been arrested five hundred and ninety-seven, and there are a total of five new varieties with tentacles on their foreheads, and the number is pitiful.

After these prisoners of war were captured, they tried to use their immortal bodies and brute force to attack steel pillars and barbed wire, climb over trenches and nail thistles to resist, but they were driven back by the machine guns and grenades fired by the Xian army.

But in the end, only two people were killed, both of whom accidentally hit the head, and the other nearly 1,000 who were shot quickly eliminated from the warhead in their bodies, and they could jump randomly after half a month of cultivation.

Their diet is almost the same as that of humans, and they can eat what people can, but it seems that they prefer to eat human flesh and drink human blood, and they look at people with the same gaze that humans look at animals, cold and violent.

Walking around the periphery, Bailiyan observed the armpit people hiding in the shadows, the big eyes on their foreheads would open after dark, which was their infrared perception vision, and it was not known how far away it was for the time being.

Walking and walking, Wild Lan said darkly

"I've noticed an anomaly since the morning, and it's still going on so far."

"Anomaly, what anomaly?"

"I found five oscillators, five wireless communication sources, to be exact."

"What!" Bailiyan was incredulous, and then asked again, "Where is it?" ”

"According to my repeated calculations and measurements, among the prisoners of war is the location of the five men with tentacles and armpits on their foreheads."

"Shhh...... You're trying to tell me that they can transmit information wirelessly! ”

"It cannot be ruled out that they are wireless communication creatures evolved by axillary people, but the signal is not strong and the diffusion range is limited. They should not yet know that their fleet has been defeated, so they hope that their nearby counterparts will pick up their signals. ”

"Hell, tell me, how big the communication range is."

"It shouldn't be very big, it's only twenty or thirty miles, after all, it relies on biological energy to provide energy, and the power is very limited, if the power is too large, the biological energy consumption will also be very large, and the strength of their communication organs also restricts the power. However, if such a person is installed in twenty or thirty miles, long-distance relay communication can be realized, and the efficiency is definitely much more efficient than that of humans without wired and wireless communication.

In addition, from the density and number of prisoners of war, it can be inferred that there are not many axillary people with wireless communication organs, and the mutation rate is low. Their vision is also severely degraded, which is supposed to be the result of functional compensation. Based on my information now, they should be the liaison officers of the various detachments in the fleet.

However, if it continues to evolve and develop, it cannot be ruled out that long-distance wireless communication organisms with larger bodies and stronger organs will evolve in the future. ”

"Can you decipher the contents of their wireless communications?"

"No, it's not just telegram and binary communication, it's language communication. They can send linguistic messages directly, so to decipher their communications, it is necessary to gather their linguistic logic as soon as possible. ”

"How long will it take?"

"It depends on the density of their linguistic logic and the amount of information they have."

"Okay, I'll have people dig tunnels tomorrow and put equipment under them."

Ranch can learn the language of the species through accumulation, but it takes long-term observation and the accumulation of linguistic logic to continuously improve the target language. Bai Liyan carried a stick computer and used its own audio collection system to collect the linguistic logic of the armpit people in the prisoner of war camp.

After thinking for a while, Bai Liyan had something else to think, so she asked again

"You see, they look the same, but inside they are from different countries. If there is a civil war between them, will they not intercept this kind of wireless communication in plain language? ”

"I don't think so, you can encrypt it by implementing a combination of agreed creatures."

"What do you mean?"

"How can I say it, but all organisms with wireless communication organs can change the communication frequency by adjusting their own physiological functions, and use the band of pulse frequency to encrypt. As long as other people of the same kind remember the band of this pulse frequency, they can communicate internally with encryption.

And this pulse band, depending on the total number of cells in the communication organ, should allow that organ to be partially dormant, thus changing the pulse. ”

"Then can't you intercept this band?"

"This is different from the definition of the band frequency and encryption measures of the radio, but in general, since they belong to different countries, there must be a mechanism for encrypting internal communications. I suggest that they be tested immediately tomorrow in order to obtain their core solutions, and only then can I further analyze their properties. ”

"Well, I was thinking about it too. There is another thing I have never understood, you help me to staff the staff. ”

"What's the matter?"

"I found that the armpit dwarves have a high IQ, and the average intelligence of their scientists is definitely higher than that of humans, with this intelligence, why haven't rifled guns been developed, and so far they have been smoothbore guns, don't you think it's strange?"

The rifling first appeared in the sixteenth and seventeenth centuries, but it was not a yang line, but a yin line, that is, a rifling wire recessed into the barrel, because the technical conditions of industrial processing at that time could only process the yin line. It was not until the nineteenth century that there was a yang line, the prototype of modern rifling.

Regardless of the technological breakthroughs in a single field, the overall quality and scale of the industrial technology of the axillary people are much greater than that of the Xianguo industry, and the intelligence of the dwarves is higher than that of human beings.

After thinking for a moment, he said

"Well, it should be related to black powder, the propellant of the axillary people is black powder, and the loading of the cartridge case in the breech solves the problem of bullet loading efficiency and the reliability of gunpowder, but the problem is that black powder is easy to leave residues, and the residual residues will adhere to the barrel to produce corrosion and carbon deposits, and acid will be formed when encountering water vapor.

The axillary man's warhead has a large diameter and a larger barrel, which is equivalent to a human fourteen or fifteen mm anti-aircraft machine gun bullet, because the black powder is too large, so the residue of the residue is much more. It is several times the amount of black powder guns left in humans, so the barrel is more susceptible to corrosion and carbon deposits.

The reason why the bullets are so huge is that they are not originally used against humans, but they fight each other for civil war, but they are more than enough to deal with humans in cold weapons. The rifle is more likely to be blocked due to the accumulation of charcoal in the barrel and the residue of gunpowder, so it is not as good as the smoothbore.

Therefore, it is still a question of propellant and technical concept, for the sake of practicality and convenience of production, smoothbore guns are more suitable for the current combat conditions. And to deal with humans who are still indigenous, breech cartridge cartridge guns are already very advanced.

However, if the caliber continues to increase, if the gun is used, the redundancy of the design and the structural improvement, such as the addition of the slag removal mechanism, rifling can also be used for black powder artillery. So the fact that the guns are not rifled does not mean that their guns will not be rifled. ”

Bai Liyan agreed with Wild Land's explanation, and in the final analysis, it was the thinking concept and technical path that misled him.
