Shen Nong sat in the small cave, holding something that looked a lot like a spear launcher but was not a spear launcher.

It is one and a half meters long, cylindrical, six fingers wide, with a meniscus-shaped long board and a grip that can be grasped by the hand at the back end.

"I finally succeeded, and I don't know if it will be successful. Looking at the thing in his hand, Shen Nong said to himself, "Let's try it first." ”

I saw that he lifted the long board to the side, and a rectangular groove was suddenly revealed below, the structure of this groove was quite complicated, but three wooden hooks hanging the tendons of the beast could be clearly seen.

Shen Nong pressed the buckle installed on the grip lightly, and suddenly the first of the three wooden hooks in the groove fell vertically thirty degrees downward, and the beast tendon on the wooden hook also fell off immediately and bounced back.

"There was no problem with the first wooden hook. Shen Nong said secretly, covered the longboard back with his hand, and then pushed it in parallel, and immediately heard a 'click', as if something had been trampled.

Shen Nong pressed the buckle again, and the sound of beast tendons bursting sounded in the log cylinder.

"There is no problem with the second wooden hook either. Shen Nong nodded with satisfaction.

As concocted, with the second sliding of the long board, a very strong sound sounded after pressing the wrench.

"Perfect!" Shen Nong smiled and lifted the longboard, and he could see that there were no animal tendons on the three wooden hooks.

"This triple launcher, which I had been envisioning for a long time, was finally born. Shen Nong said excitedly.

The so-called triple burst launcher is a certain improvement on the original basic launcher.

The first thing to do with this improvement is to expand the original caliber of the launcher, after all, the inside of the triple burst launcher is to be equipped with three bone spears at the same time.

Then, compared with the basic version of the transmitter, the triple transmitter has to be equipped with a parallel structure inside, so that people can slide the longboard to make the lever between the three wooden hooks 1-3 control.

For example, after the stake makes the bone spear in position 3 shoot, you slide the longboard, and the parallel structure will automatically jump to position 1, and then you can press the shackle again to fire the bone spear that is fixed to position 1.

Once the Bone Spear in position 1 is fired, you can jump to position 2 by sliding the longboard to make the side by side structure and fire the Bone Spear in position 2.

Due to the limitation of materials and processes, this parallel structure Shen Nong can only barely achieve three parallels, and any more of this new type of transmitter will be unbearable, and forcibly adding new parallels will only cause serious damage to the inside of the launcher, and the gains outweigh the losses.

However, Shen Nong didn't ask for so much, and now the launcher has improved from only being able to fire one bone spear at a time to being able to launch three in a short period of time, which is already a great progress, and Shen Nong is very satisfied.

"An increase in caliber means an increase in body size, and an increase in body size means that it will become more bulky and inconvenient to carry, and the bone spear filling after three consecutive firing is also a more troublesome thing, or not good enough. Shen Nong said thoughtfully.

The improvement of a weapon is not so easy, first of all, Shen Nong was not a student of the mechanical department when he was in college, and he did not have so much relevant knowledge and professional ideas for transformation, and secondly, there was the problem of limited tools.

I think that when Shen Nong made a shoe cabinet at home, he had to use electric drills, cutting machines, wrenches, screwdrivers, vises, hammers and other tools. At present, in the primitive era, he can't do anything delicate if he wants to, because without tools is really similar to how a good woman can cook without rice.

Putting the dispenser aside, Shen Nong picked up the design he had drawn on the animal skin and looked at it carefully, generally speaking, if you want to reduce the size of a thing, then what you need to do is to streamline the internal structure of the thing.

But at present, Shen Nong really can't think of a way that can be streamlined correctly, because every part in the triple burst launcher is very important, and if it is removed, the triple burst will not be effective.

"Wu!"

Just as Shen Nong was pondering, Kupang suddenly walked in from outside the small cave.

Since the completion of the second district on that day, three days have quietly passed, and Kupang's injuries have also recovered a lot in these three days, mainly because Ao Gu did not cause much injury to him in the first place.

"What's wrong?" Shen Nong asked casually.

"When are we going to destroy that cannibal tribe? With them, it's going to be difficult for us to build a water pipeline for the Huatian tribe. Kupin said.

"Oh......" Shen Nong reacted at this time, mainly because he didn't subconsciously regard that cannibal tribe as a big deal at all, so he kept it in the back of his mind and didn't pay attention to it.

Looking at the windy and sunny sky outside, Shen Nong was too lazy to delay, and got up directly and said, "Then today, you go and call me the second-level warriors, first-level warriors and quasi-warriors in the tribe, I have a task to explain to them." ”

"Yes. Kubang had been waiting for Shen Nong to allow them to exterminate the cannibal tribe, and when he heard Shen Nong's agreement, he was naturally very happy, and quickly turned around and walked out of the cave.

"It just so happens that I'm short of spirits now, and if I can get the spirits in the bodies of all the people in that cannibal tribe, I should be able to completely control the gray gull. Shen Nong thought to himself.

......

On the grass.

All the men stood here, and after knowing that Shen Nong planned to lead people to exterminate a cannibal tribe, everyone was also curious, and every man wanted to join in this operation.

"Ahem, everyone should already know about the fact that we're going out this time, right? That cannibal tribe should be quite dangerous, so this time I'm going to bring some clansmen who can use spear launchers and a few warriors. Shen Nong looked at everyone and said.

"Wu, I'll use it! Take me there. ”

"I'll use it too, and I'll shoot it accurately, so let me go." ”

"Witch ......"

"Don't worry, I've already figured out who I'm going to take this time. Shen Nong pointed at Xiong Yao and said, "Xiong Yao, you stay in the tribe with Chi and Shaohao." ”

"Ahh Chi said in surprise, he was very puzzled at the moment, because in the past, there was such an action that required fighting, and Shen Nong would definitely take him.

Xiong Yao accepted Shen Nong's order with peace of mind, after all, in addition to being a second-level warrior, he also had an identity as the chief of the Huangqiu tribe.

"If you don't go, don't go, how can there be so many whys. Shen Nong said indifferently.

"......"

"Red, shaking the heavens, stopping...... Xing, and you, you, you ......" Shen Nong stretched out his hand and nodded a few more Huangqiu people: "You guys go with me this time." ”
