It was a sunny day that night, there was basically no light pollution in Shennongjia, and the starry sky was bright.

This was Lin Shuo's second night in the vicinity of Dalongtan.

The reason why he didn't do it the night before was because the information was unknown.

The Lin family hunts, and the information on the ground is collected by the Lin family themselves, and the sky has to let the Lin family's black phoenix come.

The prey is a flying bird, so it depends on Hachi's efforts and gives the bird a night to prepare.

Presumably the same is true of the Gu Eagle, it didn't attack this team from the sky last night, and it was also observing.

This is the habit of the vast majority of beast xenomorphs at present, and humans will not attack immediately when they first break into their territory, but will first secretly observe and evaluate.

This habit is the result of the survival of the fittest.

Without this habit, the contradiction with humans is too fierce and the harm is too great, and it has long been hunted by the hunters.

The last Gu eagle on the land of China, hunted in the Qing Dynasty, more than two hundred years ago, is a kind of beast that has survived in China for a long time.

To survive for such a long time, it must be more cautious by nature.

If it was a murderous genre like the caracal, it was extinct in China as early as the Tang and Song dynasties.

So last night, Lin Shuo could sleep with peace of mind, recuperate, and at the same time set aside a night of time for Lin Xiaoba to make adequate preparations for tonight's hunting.

At this moment, the bonfire next to everyone was blazing, forcing back the chill of the mountain night, and also bringing a certain degree of light.

But with Xiao Ba's reminder in the sky, Wei Xingshan and Zhou Lingshi fought together, and the cold hair stood up all of a sudden.

Stuff out of the water.

Wei Xingshan hurriedly raised the *** in his hand and looked at the sky for a while.

It's a pity that in the high-powered scope at this time, Wei Xingshan can't see anything other than stars.

At this point, he finally remembered something, and quickly asked, "Lao Lin, how big is this Gu Eagle?"

"It depends on the variety. Lin Shuo sat still at this moment, and the Flying Yaksha was placed horizontally on his knees, "In the past, there was the largest Gu Eagle in the Hexi Corridor, named the Golden Beak Gu Eagle, with a wingspan of more than fifteen meters.

However, the strength of the Gu Eagle is not absolutely related to the size of the body.

That kind of golden-beaked eagle, on the contrary, is the weakest of the Gu eagles, without our hunters' hands, the Qin Dynasty army used Qin crossbows back then, and basically killed them all.

can occupy the mountain as the king in today's Shennongjia, this should be a sword feather Gu eagle, about the same size as an ordinary eagle, this is the strongest variety of Gu eagles. ”

"Sword Feather Gu Eagle?" Wei Xingshan asked, "What is this?"

"The reason why this sword feather Gu Eagle is so powerful is that in addition to its own extremely high level of strength and speed, the flying feathers on the wings of the male individual are extremely sharp.

Not only are the wings like a pair of machetes, which can kill prey in hand-to-hand combat, but the row of flying feathers can even shoot out of the body when necessary, and they are launched like hidden weapon throwing knives, which is difficult to guard. ”

"I'm going, so powerful?" Wei Xingshan was stupid.

"Of course it's amazing, back then, in order to compete with this thing, the hunters lost a lot of good hands, and they were helpless for a while. ”

"Then how did this thing become extinct in the land of China?" Wei Xingshan asked.

"There are two reasons, one is the constant hunting of our hunting door.

Later, we found out that this kind of Gu Eagle is dioecious, the male is not easy to deal with, and the female is not so powerful.

Therefore, my predecessors in the hunting sect focused on exterminating the female Gu eagle to restrict the reproduction of the population of this kind of thing.

However, the female of this sword feather Gu Eagle is slightly weaker than the male, and it is still a very powerful beast alien.

And don't look at this kind of thing, the male and female usually don't live together, but in fact they are monogamous, and once the female is attacked, she will use a special chirp to call the male out of the nearby waters.

Often, before the mother has been taken, the hunter will shoot the feathers from the back.

In short, for this kind of thing, we also suffered heavy losses back then.

Yunmengze was once one of the forbidden areas of Chinese civilization. ”

"Yun Mengze?" Wei Xingshan was stunned for a moment, "What kind of place is this, it sounds familiar." ”

"This is the ancient place name, in Chudi, which is now the Han River Plain.

Before the Qin and Han dynasties, there were still continuous lakes and swamps near the Hanjiang River Plain, and there were a large number of primeval forests around it, and this place was called Yunmengze.

This kind of environment is also extremely suitable for the survival of this kind of sword feather Gu eagle.

The male is in the water, and the female is in the forest.

This thing later disappeared in Huaxia, in addition to being taken care of by our hunting door, the second reason and the main reason is that the geographical environment of Yunmengze has gradually changed.

With the continuous impact of the Yangtze River and the Han River, Yunmengze gradually disappeared and became the Jianghan Plain today.

This has caused the vast majority of sword feather Gu eagles to gradually migrate south, and the existing populations today are basically in Southeast Asia.

I estimate that the current Gu Eagle in Shennongjia is the cub that Ma Yixian caught in Southeast Asia, and it has grown up at this time. ”

"Then how powerful is the flying feather of this thing?" Zhou Lingshi asked at this time.

"I don't know exactly how powerful it is. Lin Shuo said, "However, on the list of the dead of the Hunting Gate that year, there were several Su family inheritance hunters, and those seniors were all from the Nine Realms.

The hunters of the Su family, once they enter the Nine Realms of their own inheritance, their swiftness and vigor of their body will inevitably crown the hunting gate.

They will all die under the feathers of the sword, and you can see how powerful this thing is.

Anyway, now this black light is blinding, this Gu eagle's flying feathers, I don't want to take it hard, do you two have this interest?"

"Absolutely not!" Wei Xingshan and Zhou Lingshi shook their heads like rattles.

Among them, Zhou Lingshi asked: "Master, now that this Gu Eagle is flying in the sky nearby, aren't you worried at all?

"The flying feather of the sword feather Gu Eagle, this is the life-saving skill of this beast.

Once the feathers are ejected, it can't fly and has to stay in the water for a year or two before it can slowly grow new feathers.

If it was left in the previous Yunmengze, it didn't have to worry about this matter, because there were fish in the water, and the mother would also send it food.

Now this Gu eagle is surviving in the Great Dragon Pond, and the little aquatic product near the Great Dragon Pond is definitely not enough for it to stuff its teeth.

Moreover, the beast aliens in the entire Shennongjia forest area are now in famine, and once it loses its ability to fly, it is very likely to be fatal.

So as a last resort, it won't shoot down its feathers.

Moreover, this kind of heavenly beast is proud by nature, as long as it flies in the sky, it will not pay too much attention to the things on the earth.

As long as you don't look at the sky, go to it, and at most it will observe you silently, and it won't fight with you.

All we have to do now is keep chatting and pretend it's okay.

So Lao Wei, if you use this gun to aim at the sky again, our door may really be extinct. ”

"I'll go!" Wei Xingshan shrank his neck and quickly put down the gun in his hand, "Why didn't you say such a big thing earlier!"

"If I don't explain the reason to you, how can you, an apprentice, learn the ability?" Lin Shuo asked rhetorically, "Besides, using a pole to pestle the sky is not a fatal threat to the Sword Feather Gu Eagle, so it won't quickly summon its flying feathers down." ”

"Master. Zhou Lingshi asked, "Then we're just talking like this now, and we don't look up at the sky, so how are you going to hunt that Gu eagle?"

I know, the eighth master is staring at the sky at this moment, but how can you two cooperate?

There is also the eighth master's 'night stargazing and positioning and locking the enemy', what kind of lock method is it?"

Lin Shuo glanced at his second apprentice: "Zhou Lingshi, what level is your cultural class?"

"I didn't go to school. Zhou Lingshi scratched his head, "But my former master Wu Tiannan taught me for a few years." ”

"How about mathematics, physics and chemistry?" Lin Shuo asked.

"I haven't studied much. Zhou Lingshi shook his head, "But I know a little bit about arithmetic." ”

"Do you know the coordinates?"

"I know. Zhou Lingshi nodded.

"Then I'll be able to explain it to you. Lin Shuo nodded and said, "I'll talk about positioning first." If we want to determine the location of an east and west, we often need specific geographical coordinates, which are east longitude and north latitude when resting on the ground. ”

"That's right. ”

"Then if we want to determine the position in the sky, do we also need coordinates?"

"Hmm. ”

"So the coordinates in the sky, do we have a ready-made system called astrology?"

"Oh. Zhou Lingshi's eyes lit up.

"No, it's like you get it. Lin Shuo said lightly, "The coordinate system of the stars is not fixed.

The stars in the sky, the three walls and the four elephants and twenty-eight constellations, are roughly centered on the North Star, and they continue to rotate with the change of seasons.

And the closest star to the North Star is the Big Dipper.

Therefore, the stars in the sky are in the Beidou.

At the same time, because of the change of the Earth's axis of rotation, the position of the North Star has also changed from ancient times to the present, which is called precession.

This is a dynamic coordinate system, and if you want to determine the fixed position in the sky, you need to combine it with the calendar.

Every moment, the position of every star in the sky, we, the Lin family hunters, ask to know without looking up.

Because we humans can't see the stars during the day, we must remember it in our minds.

If you remember this set of things, you can cooperate with the Lin family's Heifeng. ”

"Lao Lin, then why do you and the Eighth Master want to set the position of the heavens?" Wei Xingshan asked.

"Well, that must be a way to determine the enemy's position in the sky. Zhou Lingshi said.

"It's not. Lin Shuo shook his head, "Old Wei is a sniper, he can realize this, you can't realize it when you are Zhou Lingshi." I'm not the enemy's position. ”

"What's that?" Zhou Lingshi asked.

"Direction and elevation angles of ballistics. Lin Shuo said, "This system is applicable to the time period, not only at night, but also during the day.

The prey targeted is not only flying in the sky, but also running on the ground.

The core of the system is not me, nor Lin Xiaoba, but Chaye.

In modern military terms, this is an over-the-horizon combat system.

I don't need to see the prey, I first use the Lin family's 'smell the wind to identify the position' to roughly know the location of the prey, and open the bow in advance.

Lin Xiaoba observed the position of me and my prey in the sky, fixed the trajectory, and then notified me with the name of the constellation.

After I fine-tuned it, I shot an arrow into the sky, and the hunt was over. ”

"Oh, I see. Wei Xingshan suddenly realized, "This is the same reason as the cooperation of anti-aircraft guns and unmanned reconnaissance aircraft." ”

That's what it means. Lin Shuo nodded, "But today, it's a little troublesome." ”

"What's wrong?"

"The core of this system is chasing the master, chasing the master after the meticulous maintenance of the He family's blacksmith, the force of each bow is constant, so the landing point of this trajectory, as long as there is a direction and elevation angle, I add a little bit of error caused by the wind direction, then it can be determined.

What Lin Xiaoba mastered was this system.

After all, it is a starling, no matter how smart it is, it has limits, and it is not easy to make it remember the changing stars and the elevation angle of the shot under a fixed force.

Then let it learn the ballistic function and calculate various ballistic trajectories under different forces on the spot, which is impossible.

Don't talk about it, if you change someone in the sky, you don't have any calculation tools at hand, if you are not a genius in mental arithmetic, it will be no fun.

Therefore, the force of this beast fork shooting out cannot be changed, it has to be the same as the shooting power of chasing the master.

This trip to chase the master is not around, so the strength of its old man's bow, I have to use the way of throwing to simulate.

Once there is a deviation in the strength of the hand, it will be a thousand miles away.

And the angle of this shot is also a difficult point, so it is not as easy to grasp as it is to open the bow directly.

So I'll say it first, and if I go back and go up, you're not allowed to laugh at me. ”

"Then what if we can't hold back and laugh out loud?" Wei Xingshan asked.

"Expelled from the division on the spot. Lin Shuo said lightly.

There was silence around the campfire.

Lin Shuo then said: "But if I fail this time, I shouldn't have to expel you from the division. ”

"Why?"

"The Gu Eagle is not stupid, if I miss this time, it must have counterattacked with flying feathers. It has eighteen flying feathers on one wing and a pair of wings, which is a flying knife array composed of thirty-six flying knives. Lin Shuo said, "When the time comes, the two of you will be gone, why should I bother with that effort." ”

"Master, I have confidence in you, you will definitely be able to shoot!" Zhou Lingshi hurriedly said.

"Senior brother, don't listen to him scare people, tonight's prey is in the sky and not on the ground, the entire trajectory is short, and there is only the upper half, and the allowable error value is much larger. Don't be afraid, you should not be far from ten. ”

Wei Xingshan said calmly as he took out a steel helmet from his bag and buckled it on his head.

"Senior brother, your helmet is good, is there anything else?"

"No, that's it. Wei Xingshan straightened the steel helmet and quickly fastened the buckle.

"Senior brother, I'm junior brother, you have to let me, why don't you put it on for me first?"

"Get out of here, I'm ten years younger than you. ”

"This doesn't look at age, it depends on the entry sooner or later. Zhou Lingshi turned his head to Lin Shuo and asked for help, "Master, you take care of it." ”

"Let him wear it, anyway, the steel helmet of the Gu Eagle's Flying Feather can't stop it. Lin Shuo finished laughing, and then finally figured out the taste, his face stiffened, "What do you two mean?"

At this moment, Lin Xiaobayi's voice in the sky came from afar.

"Brother Shuo! ”

Lin Shuo didn't have time to worry about these two apprentices, and slowly stood up.

He shook his shoulders and changed the "Flying Yaksha" in his hand from holding it flat with both hands to holding it backwards with his right hand.

Ready to make a gesture, Lin Shuo said, "Old Wei, who told you that tonight's prey is only in the sky?"

"Huh?"

"On the ground, too. ”
