Compared with the bow and arrow that suffered from frustration in research and development, the research and development of new weapons here was much smoother, and it was so smooth that in less than an hour, Luo Ji made the first sample.

That's right, after Luo Ji took a step back, the new weapon he chose to make was the sling! To put it simply, it's a slinger, which is probably the oldest long-range class of human civilization, right?

In ancient times, he didn't know how to make a sling, and he hadn't studied it, but the structure and production of the slings were obviously much simpler than the bow and arrow, he asked someone to find a piece of tough animal skin the size of a palm and four animal tendons used to act as ropes, considering the problem of strength, he braided the two animal tendons into one in a spiral weaving way, and then forcibly pierced four small holes with a stone spear at the edge of the animal skin, one on each side, and passed the woven animal tendons through the small holes, and tied the knot and buckled, a simple slingling was completed.

System Prompt: Congratulations to the player 'Luo Ji' for successfully crafting the 'Sling' to gain 30 Civilization Points and 3 Military Points.

The system's reminder made Luo Ji more confident, and with the newly completed sling, he walked towards the outside of the tribe with great interest, whether the new weapon is good or not, he has to try it to know.

The five members of the Ordnance Department followed one after another, and they were obviously very curious about this new weapon in the hands of their patriarch with a simple shape, but they had never seen before.

On the way to the experimental site, Luo Ji didn't let the five of them idle, and collected a lot of stones of suitable size along the way as ammunition for the catapult, and also called Luo Yong, Zhao Pan and others who were training.

After all, he made this sling, which was for these warriors in the tribe, however, their tribe is now short of manpower, and it is impossible for Luo Ji to increase the number of warriors in the tribe in a short period of time.

In this way, the candidates for this slinger can only be selected from the existing tribal warriors, but four of the wolf warriors are on the side of the Black Rock tribe, so there are only fourteen warriors on the side of the Spiegel tribe at present.

After some period of rigorous training, the fourteen tribal warriors finally had a somewhat disciplined and well-trained feeling, standing there in a neat row, giving people a much more reliable feeling.

No nonsense, Luo Ji personally went into battle to demonstrate, who called this group of people, and he had a little research on this newly made sling?

Carrying one end of the slingling in his hand, and then putting a round stone about the size of a tennis ball on the animal skin, to be honest, Luo Ji was quite nervous in his heart, he hadn't really used this sling, in case he missed and injured himself by mistake, wouldn't he, the patriarch, be very faceless?

"Calm." After comforting himself in his heart and adjusting his breathing at will, Luo Ji's mood quickly calmed down, "It should be the same principle as turning the pen, anyway, it is to use the centrifugal force that rotates up......"

As soon as he thought of this, Luo Ji grabbed the hand of the slinging rope and shook it lightly twice, looking for a feeling, and then with a force, the slinging rope in his hand suddenly spun rapidly, making a whistling sound.

Luo Ji's movements caused a burst of exclamations from everyone behind him, and a pair of eyes full of curiosity suddenly focused on the constantly spinning sling.

didn't do much grinding, with a feeling of dying early and surviving early, and losing people, Luo Ji saw an opportunity and threw the slingling that was quickly spinning in his hand into the distance! The stone placed on the animal skin flew out with a thud.

His strength is okay, coupled with the blessing of centrifugal force, the stone flew far away, Luo Ji saw this, he finally breathed a sigh of relief, and at the same time secretly glad in his heart that he had not died before to put a target on the opposite side, otherwise according to his accuracy, it would be enough to make him burst into tears.

"Uh-huh!" With a heavy dry cough, Luo Ji turned around solemnly, feeling the eyes full of surprise, excitement and admiration, and his self-esteem was suddenly greatly satisfied, "Anyway, that's it, who wants to try it?" ”

"I, me!" As soon as he heard this, Luo Yong, who had long been eager to try, hurriedly said that he wanted to try.

Luo Ji didn't care, he directly handed over the slingling in his hand to Luo Yong's hand, and after explaining the key points of the operation to him, he asked him to try it himself.

The difficulty of the slings itself lies in how to control the accuracy so as to hit the target relatively accurately, and it is not too difficult to just throw the stone projectiles.

I saw that after Luo Yong put the stone, he smoothly let the slingling spin, he was very strong, just waving and spinning, there was a feeling of amazing momentum, however, before Luo Ji sighed for a second, at that time, only heard a muffled sound of 'bang', the stone bullet carried an amazing power, smashed heavily on the ground, and directly smashed out a small pit the size of the bowl, and the visual range was about ...... Well, five meters......

"Poof!" At that moment, Luo Ji couldn't hold back at all, and accidentally laughed.

And Luo Yong's face turned red on the spot, although Luo Ji did not explain the standard, but looking at the distance of the stone projectile flying out of Luo Ji's previous demonstration, and then looking at him, anyone can see how bad his hand was just now.

As a long-range weapon, what kind of fuss do you want to make trouble with a range of about five meters? It's better to rush up with a stone spear and fight for Lisuo in close combat.

The smile on his face was slightly retracted, Luo Ji stepped forward in two steps and patted Luo Yong's shoulder, "Okay, replace the next one, everyone come over and get acquainted with it, and then I will pick four or five of the best people among you to specialize in practicing this sling." ”

Rayong's problem at that time was obviously that he was too strong, and he hadn't seen the timing yet, so he would throw that ridiculous range, but it didn't matter, as a fierce general who could charge in the front row, Luo Ji didn't plan to let Rayong turn into a slinger at all, but it was obviously unreasonable to try not to let him try, just take advantage of the moment just now, let him dispel that idea.

After appeasing Luo Yong a little bit, and publicly stating that both slingers and melee fighters have their own advantages, and there is no difference between strength and weakness, Luo Ji turned his head and asked the people of the Ordnance Department to make a few more slings according to this style, and then let them practice first, although the recent development of the tribe has been on the right track, his daily work is still not easy.

After such a long time, the fortifications on the outskirts of the Spiegel tribe are almost half built, and it's time for him, the patriarch, to go back and continue to fight against his 'pulley group', and at the same time, the design of the entire city gate must be drawn quickly.
