The feathers of the dinosaur bird are quickly plucked after being shot down, and then carefully preserved, which is the material used to make arrow feathers. The purpose of the arrow feather is to make the arrow's trajectory more stable. A similar application can be seen in a rocket launched by North Korea, which has a ring of lattice at the tail that appears to increase drag. That's what increases stability. (The world-class aerospace technology of China, the United States and Russia has accumulated aeroscience very well, and there is no such design). Anti-tank missiles also have this seemingly useless lattice to increase drag, but it is necessary.

Without arrows, arrows are easy to shoot out of arc trajectories, (Lu An's first shot was a continuous dismissive hit, and he was amazed that the tracks of the three arrows were all curved, but they accurately pierced the target.) The women in the procession sharpened the bone arrows next to the campfire, drilled a smaller groove at the tip of the shaft, inserted the arrowheads, and tied them with fine straw thread. Then use a stone knife to make a cut in the tail of the shaft, insert the feather into it, and then glue it tightly.

Now the women in the team look different from the delicate ones at the beginning. They began to work making weapons, tending to fires, and carrying some of their luggage. At the same time, they began to pick up bows and arrows, and when the men used their javelins to block large prey, they used their bows and arrows to restrain their heads.

Under the suggestion of Li Sanxiang and the arrangement of Si Xuan and Zhao Chenggong, the team was on the right track. There are no fools in the whole team, and when Aunt Liu Lan died, the women gradually felt the crisis, which came both from the outside and from the inside, male humans.

The change of the women in the team was in the ten days that Lu An picked up the bow and arrows to shoot. It was also within a dozen days that Lu An determined that Li Sanxiang had given up the murder of another person in his plan. Start adjusting the goal of the calculation to another person.

Night soon fell, crackling in the fire, river water boiling in clay pots, and some fruits were boiling in the water.

Lu An sat on the ground with his knees crossed, trying to count the stars in the sky, and at the same time picked up a pen and named each star on a leaf, Lu An divided the sky into seventy-four constellations, of course, the names were all Lu An's own nonsense, there are aircraft constellations, squid constellations, mainly for his own memory. The starry sky of the age of dinosaurs is not the same as the starry sky of modern times.

Lu An knew that he might be bored by doing this, but he followed his boring thoughts and started to do it. Perhaps in the primitive era, the first people to study the star calendar were as boring as Lu An. Without the boredom of those people, the cultivation of primitive humans would never have been able to develop.

Because only when the astronomical calendar appears within the civilization can there be the concept of agricultural time. Africans are very skilled in hunting, and the Maasai are considered to be the most powerful hunting race in the world. But the whole of Africa, except for the ancient civilization of Egypt, had an astronomical calendar. Black Africans seem to be lacking in this regard.

Lu An, who was concentrating on counting the stars, spent all the rehearsals on counting the stars, the vast starry sky. Thousands of stars that followed a fixed trajectory immediately attracted Lu An's interest. Lu An carefully took out a blank piece of paper and recorded it against the sky. This night was a night for Lu An to feel at ease, and it was rare for him not to have a random rehearsal.

However, Lu An also paid attention to the situation in the team on the side, and Lu Buzhi, one of the adult males in the team, began to take reckless steps, and Lu Buzhi mixed with Zhao Chenggong in the past few days. There were now eight men in the team, two of whom were wounded by the dinosaur's claws in the shoulder when they were scolding the dinosaur, and now they were red and swollen, and they were in a very quiet state. Zhao Chenggong, the taxi driver, and Lu Buzhi and the two injured men have gradually formed a small circle.

This small circle is now very dissatisfied with the current situation of the team. That is, the manpower is not concentrated, there are eight men in the team, Si Xuan is nominally the leader, but the five-person group has increasingly disagreed with Si Xuan's leadership.

Luan walked into their coterie during the rehearsal and saw it in the rehearsal. These men welcomed their little brother affectionately. - It's an obvious pull.

Even if there is no rehearsal, Zhao Chenggong's mind is like Sima Zhao's heart. In the small circle, several other men openly called him big brother. It's obvious that it's like he's the head. And Zhao Chenggong also recognized this title. It's a big brother's style.

Every time Lu An saw Zhao Chenggong like this, he lamented in his heart that Zhao Chenggong was such a big person, how could he be so easy to expand? You can pretend to be a big brother in front of social gangsters, but can you pretend to be a big brother in front of some people? The gangsters are black in their hands, and in the officialdom, they are black-bellied.

When Zhao Chenggong was inflated, Lu An observed Li Sanxiang with a rehearsal at the same time, and Li Sanxiang still had the smile of a good gentleman. But how Lu Ann looked and felt that there was something underneath that smile. And Zhao Chenggong didn't seem to notice what the smile on Li Sanxiang's face meant.

Now Lu Buzhi is just in Zhao Chenggong's small circle, and he has just talked about some meat jokes, and his heart is itchy. The color is born to the side of the gall. Moved to the lady with frivolous steps.

Under the disgusted gaze of many women, he stared cheekily at the bare shoulders of the women (for six months, the fabric on everyone's body barely covered the vital parts). whistled at the female white-collar worker: "Sister Cha, are you lonely these days?" My brother is a little restless here. ”

The female white-collar worker surnamed Cha thought of the painful experience a few months ago, and couldn't help but shrink back into the team.

At this time, Yan Yun protected Cha Hong and said, "You get out of here, you are not welcome here." ”

However, Lu Buzhi did not give up, but continued to laugh at Yan Yun: "Why don't you come and accompany me?" ”

And then he couldn't speak, Yan Yun pulled up his bow and arrow with his backhand and pointed it at him. Lu Buzhi, whose face turned purple, immediately fled. And at this time, Si Xuan rushed over. looked at the direction in which Lu Buzhi left, and asked Yan Yun, "What happened?" ”

Yan Yun didn't make a sound, while the other women talked nonsense. But in a few seconds. Zhao Chenggong came with a few people.

Lu An heard the reason why Zhao Chenggong came over in the rehearsal, Yan Yun pointed at Lu Buzhi with a bow and arrow, and Lu Buzhi was Zhao Chenggong's younger brother, Zhao Chenggong felt a big loss of face and decided to come back to the field.

And the next thing is that Zhao Chenggong and the three of them confronted Si Xuan, who was holding a knife. And behind Si Xuan, Yan Yun and Bai Lu pulled up their bows and arrows. Lu An, who was counting the stars more than ten meters away, moved his position outward, indicating that he did not want to get involved in this matter.

Lu An looked at the future rehearsal and sighed in his heart: "It's really noisy." ”

It was a standoff, and the team began to split into two parts for a standoff. Li Sanxiang walked to Yan Yun and Bai Lu at this time, pressed Bai Lu and Yan Yun's bows and arrows with his hands, and at the same time glanced at the two behind Zhao Chenggong with his meaningful eyes. The two of them couldn't help but have the intention of retreating.

At the same time, Li Sanxiang said to Zhao Chenggong: "Success, brute force can't solve the problem, why can't you talk to everyone well, but you have to be so aggressive?" ”

In the distance, Lu An heard Li Sanxiang speak like this, his eyes closed, and he said silently in his heart: "It's going to start." ”

The so-called bystander is clear.

Li Sanxiang let the women's side be led by Yan Yun, and let Zhao Chenggong's side also form a small circle, which is why a confrontation can be formed now.

People have such a problem, after forming an alliance, they feel that they are backed by a big tree, they want to rely on this big tree, and they mentally estimate that they have formed an alliance, and the risk level of their actions for themselves has been reduced, and they think that their own code of conduct can be bolder. And the other side has also formed an alliance and will think so. So the contradiction detonates directly.

The struggle for hegemony in the Greek Staba is like this, and it is a war between two small city-states that induces two alliances. And the same was true of the First World War, when Britain and Germany began to form an alliance to form two major military blocs to confront each other, coupled with the fact that the fools in the Balkans thought they had backers and began to provoke each other. Straight to the fight. Those small countries in the Balkans in World War I did not dare to directly provoke the two giants of Britain and Germany, but directly relied on their allies to provoke opponents of the same level.

There can be no world war without a military alliance, just like in the 21 st century, the two countries of Northeast Asia and Japan are very rational in the face of China, and they will not move. The Japanese know that even if the U.S.-Japan security agreement is reached. If it wants to provoke too much, the United States will not be able to cover itself. But in the face of North Korea, Japan fanned the flames with all kinds of excitement. I can't wait for the two military allies, the United States and South Korea, to fight directly in North Korea.

And now looking back on the current contradiction, Lu Buzhi only had the courage to go to the women's camp to flirt with Zhao Chenggong and others after calling him brothers. As for how did he get his guts? - Borrowed.

And why is Zhao Chenggong standing here now, but out of face, just like why did Germany rush to war without being prepared for World War I? For the sake of the Covenant, for the sake of Germany, not to lose Austria-Hungary as an ally.

And now if Li Sanxiang really wants to stop the contradiction, he should give Zhao Chenggong a face-saving step, but Li Sanxiang didn't. Rather, it is "persuasion". It seemed to show a high posture, but he pressed the bows and arrows of the two women. creates a posture that seems to take the initiative to ease the situation, but gives the other party a chance to learn.

Zhao Chenggong's face was blue and white, he looked at Li Sanxiang, and then at Si Xuan. Suddenly smiled and seemed to give up, but suddenly his footsteps rushed forward. Stabbed towards Si Xuan. In Zhao Chenggong's opinion, when he gets to Si Xuan, he is the strongest person in the team, and at that time, Li Sanxiang, a good gentleman, must swallow back his words. He was carried away by a moment of rage.

"Er Dare" shouted when Zhao Chenggong was in trouble. With one hand, he first pushed the wooden gun to prevent the wooden gun from hitting Si Xuan's vital point, and then held the wooden gun in Chao Chenggong's hand to prevent the wooden gun from continuing to advance, while the other hand pulled out the wooden dagger and plunged towards Zhao Chenggong's vital point. Blood splattered out.

Zhao Chenggong died, and when he was dying, his eyes were filled with disbelief, as if he had met Li Sanxiang, a seemingly amiable person, for the first time. He miscalculated Li Sanxiang, Li Sanxiang's role in the team has always been very gentle, but at this time, this person whose face was covered with his own blood and did not hesitate to stab the wooden thorn into his neck, Zhao Chenggong felt very unfamiliar.

"Why don't you hurry up and get the herbs?" Li Sanxiang ordered Lu Buzhi and another driver, and the two of them, who were in a state of confusion, immediately ran over to rebuild the medicine, (a kind of palm mashed leaf pulp). Li Sanxiang's order was very effective. It is far more clever than Wang Yun killing Dong Zhuo and then forcing Li Dao and Guo Yan to rebel, and it is also more clever than Chongzhen killing Wei Zhongxian and suppressing the eunuch class to the end.

Since it was a bone spur, if it was a metal spur, Si Xuan was already finished. Rao is so, Si Xuan's shoulder blade is also injured. In Yan Yun's cry, Si Xuan solemnly handed over the metal knife in his hand to Li Sanxiang.

Lu An, on the other hand, was rummaging around with the dinosaur's skull.

Dinosaurs had very small brain volumes. Even the smartest dinosaur in the Cretaceous was only able to compete with ostriches at that level. The human brain seems to be too much to deal with the beasts of this era, and it seems to be calculating the same kind of people a lot, Zhao Chenggong is calculating the same kind, and he is being calculated by another guy after all.
