Double Helix of Dajian Doujin

Davis coefficient, a dimensionless number representing the ratio of the range to the size of the launcher, is one of the weapon development standards in the era of visual range weapons, which is equal to the range divided by the signal radius of the launcher.The signal radius is generally taken as half of the distance between the farthest two points of the transmitter itself.

The Davis coefficient first appeared in the literature on the history of weapon development, and was used to classify the types of weapons with different ranges for similar users, and to analyze the development trend of long-range weapons.However, later weapon makers tried to increase the range of weapons as much as possible, and generally rarely used this factor.Only the researchers of the optical stealth system are still using the dimensionless evolution of the Davis coefficient - the environmental Davis coefficient, that is, the minimum value of the range and the expected distance of the environment divided by the signal radius.It is used as an important parameter for the difficulty of stealth.

For example, although the Titan battleship is 31 kilometers long, its environmental Davis coefficient is very large.Therefore, the optical stealth system of the Titan battleship is much better than the infantry on the ground whose signal radius is only more than 1 meter.

The small town called Pieta in front of me looks similar to a small town with a defense level of E in Huayu Plain.The only difference is that in the Eminole Continent, no matter which country it is, any residence called a town has defense facilities, even if it is just a few meters high earth wall; if it is a residence called a village , regardless of the ethnic group, the biggest feature is that wooden houses are in the majority.Although the small town in front of me has masonry structures, there are no fortifications around it.

"When did the taste of demons become so good?" (Elvish language)" Although the optical cloaking system was turned on, Lin Yushang was still hiding behind the pillars on the top of the clock tower and secretly observing the entire square. What about the beautiful girl. (Elvish)" Through the display screen, Lin Yushang could clearly see the faces of everyone in the square.Undoubtedly, those tall women in the square wearing tights and carrying big swords - really big enough, the length of the blade alone is more than 1.5 meters, and the thickness is more than 5 centimeters - Almost all fighters have outstanding appearances, and it is not too much to describe them with angel faces and devil figures.It's just that the uniform blond hair and silver eyes are different from the ordinary people around.

Looking at it, Lin Yushang said another sentence: "Those swords, aren't they all magnesium-aluminum alloys?" It looks very muscular, like someone who uses this kind of heavy weapon. As long as other people change their clothes, you will definitely think that this is a weak woman rather than a warrior.Lin Yushang is very familiar with warriors who use two-handed swords. When he served in the small mercenary regiment in his early years, the entire small mercenary regiment basically used two-handed swords.It's not that there are no women among them, but no swordsman with a big sword who mainly uses force to attack will grow up like this.Even the girls in the Demon Sword Battalion, it is extremely rare to see such frail people.After all, even magic swordsmen rely on their swords for food.Magic is only to contain the enemy, killing people is still a sword.

However, this suspicion did not last long.Soon, Cortana reported that the main constituent element of these weapons is iron element.In other words, such a big sword weighs at least 20 kilograms.Lin Yushang was even more surprised by the rude way of greeting between the two soldiers on the side of the square.A short-haired warrior took advantage of another short-haired warrior who was talking to other people and didn't pay attention to himself. He suddenly drew his sword and looked over with a jump.The level of ease is like holding a thin bamboo pole instead of a big sword in his hand.The performance of the short-haired warrior who was cut off was even more surprising. After all, the cut-off warrior still held the sword with both hands, and the cut-off warrior held the sword with one hand when he felt the danger, and blocked the jump. .

Lin Yushang has seen a lot of similar greetings. Residents of the Northern Federation of the Amy Empire often greet each other like this, especially the soldiers of the Xueyue Legion stationed in the Northern Federation. This kind of violent greeting is very common.However, Lin Yushang has never seen a sword that weighs more than 20 kilograms so easily with one hand.Although the ability to enhance physical fitness with magic or energy assistance is very common, even the top priest (best at all kinds of auxiliary magic), release the most powerful auxiliary magic, and bless any human being in the top ten of the battle spirit list , cannot achieve this effect.If possible, it must be a race like dwarves or berserkers that are known for their strength.

"Sir, maybe this is a new type of enemy's experiment. It's not unheard of to use energy to assist physical attacks, but it's the first time I've seen one that can achieve this kind of utilization efficiency. (Elvish language)"

"Just now I was going to knock out a single person, and then ask about the situation. Fortunately, I watched it for a while. (Elvish language)"

"Sir, isn't this a violation of combat regulations? Without knowing the enemy's capabilities, even if you want to collect intelligence, you should use a rifle to break the neck and extract the memory. (Elvish language)"

"Um, it's just a whim, it's just a whim... (elven language)"

"..."

Just as Lin Yushang and Cortana were laughing, the soldiers in the square gathered together, led by a beautiful woman with long hair and a prickly hair (Author: Why does this word sound so twisted? Everyone: Shoot Fei, thank you for claiming to like Miss Mi.) Standing on the high platform in the square, I don’t know what to announce, causing a row of riots below.At this time, another beautiful woman with long wavy hair stood up and put her hand on the hilt behind her back. Suddenly, a whirlwind was generated, and the snow under her feet was blown away.The riot was stopped immediately.

"Damn, Cortana, change the triggering rules of the automatic escape system. Now it is set so that as long as they approach or even find us, we will immediately teleport to the nearest safe point. It seems that we must never get close to them. Just now What did she do? Could it be that she cast some magic? Could it be that she drew her sword and swung it? (Elvish language)" From the headset, Lin Yushang understood that the soldier just swung his sword, It's just that Lin Yushang thought it was too incredible, so there was still doubt in his tone.Such a fast speed is obviously very dangerous if you come into close contact with it.Therefore, Lin Yushang immediately asked Cortana to change the trigger rules of the automatic dodge system.The system can force the user to be sent to a set safe place without the user's consent after the trigger condition is met.Generally speaking, the trigger rule is that the shield value is less than a certain value, or a certain layer of shield is completely broken.Unless it is extremely dangerous, it is rare to escape when it is detected.

"Sir, I changed this setting just after I saw the two short-haired warriors greeting each other. These people are very powerful in melee combat, and we'd better keep a distance. (Elvish language)" Obviously, the artificial intelligence In terms of safety, he is more conservative than Lin Yushang.

"Your hand is really fast...By the way, what is the word 'awakened'?" (Elf language)" For the information helmet worn by Lin Yushang, when hearing this kind of proper noun, it should be Information about such things will be displayed in front of your eyes.But when it comes to the word, it doesn't show.

"I don't know, there is no such word in the thesaurus just extracted. It may be that the local residents don't know what it is. (Elvish language)"

"Okay, let's observe for a while and listen to their conversations. It seems that we will come into contact with this kind of thing in a while, and we will see when the time comes. Now, continue to monitor and get more information. (Elvish language) "Lin Yushang's eyes turned to the square again: "They are taking roll calls, remembering everyone's name, voice, appearance and other information. Also record the number with the same ranking, as well as the symbols on their swords and clothes. Possibly looking for logic. It might help later if we need to hack into their chain of command. (Elvish)"

"Okay, sir, this is on the record. I suggest that we keep a low profile for the next few hours. Do not engage with them, and, I think, even if they are powered by the Burning Legion The demons in the world can't explain who they are from the Burning Legion. In the past, the orcs of Draenor also used the energy of demons. Although most of them were controlled by demons, there were also some People can successfully use demon energy against demons. We may have encountered a similar situation here. They did not attack ordinary local civilians, which is very strong evidence. (Elvish)”

"I understand, so now I really want to know what are the enemies of them. If possible, these people may be our potential allies, not to mention, you also know the country's expansion plan Right? Maybe here is an opportunity, since the higher authorities have given me the right to deal with it on the fly, we should try our best to fight for the interests of the country. (Elvish language)”

"Understood, sir... um... I don't know if I can participate in expressing political opinions... Do you think that plan is feasible? (Elvish)"

"Cortana, in my mind, you are now one of us, so feel free to speak up. Regarding the feasibility of the territorial expansion plan, I am actually not sure, but because of this, we are going to try Well. (Elvish)"

"Okay, I understand. They're disbanded now. Uh... there are 3...not 4 people left the city. Everyone else went back to the room to rest, the drone is trying to approach, please wait a moment. (Elvish )”
