"What's the use of the mechanism? The machine gun is pretty much the same! Xiao Zhen, you make me one! The kind that will clatter as soon as you fire!" Ruan Xiaomeng imagined the mighty and heroic posture of firing wildly with a machine gun in her hand.

Although the crossbow arrow is very good, it is obviously not powerful enough, and he didn't hit him so close to Nangong Muyun that day!

The rainstorm pear flower needle is not bad, but you can't always carry it with you every day, it's awkward to death, and the lethality is not good, you can't shoot people! Nangong Muyun has been shot into a hedgehog and can still run away calmly.

If it's a machine gun, rattle......

"I can't make that, I have to have steel, and the lathe is ......" Xiao Zhen said that it is difficult for me to cook without rice.

"Then it's okay to make me a grenade, just like in the game, you can blow people up if you throw it out!" Ruan Xiaomeng had no choice but to settle for the next best.

"Hmm...... This is theoretically possible, but real grenade eggs can't be made, but homegrown eggs can...... But it's a pity to be a fried egg with just a little fire demon. Jane said she could really make it.

In fact, fried eggs are similar to fireworks, and as long as there are ingredients, it is not difficult to make. But the big box that the boss brought back only had two packs of black fire demons, and Xiang Ze used a lot to make fireworks, and there were not many left.

"If there are enough fire demons, you can make rockets, that one is much more powerful than a grenade egg, at least the range is long enough......," Hong Haibo said suddenly.

"Rocket eggs?" Ruan Xiaomeng was overjoyed.

"He's talking about rockets, but there are no eggs, it's similar to fireworks made by the boss, but that one is really better than grenade eggs, I think. Jane explained.

"Cut! That's a fart! Are we going to set off fireworks to welcome the bad guys when they're coming?" Ruan Xiaomeng was disappointed.

Xiang Ze was moved in his heart, the rocket is really a good idea, although it may be due to limited conditions, and the production will be relatively rough, but it is very practical.

He probably knew what Hai Bo meant, the so-called rocket was actually the feathered arrow tied to the fire demon in ancient times, which had long been eliminated in modern warfare. However, if you can create a mechanism that can fire continuously, the power of this rocket will be very great.

The firing range is long, the coverage is wide, the lethality is also large, and the main thing is controllable. This is safer than creating traps, because traps are indeed as easy to injure innocents as Jane fears.

"This sounds feasible, Hong Bo and Xiao Zhen, you can try to discuss the production, what are the difficulties, what is lacking tell me, I will find a way." Xiang Ze is tantamount to agreeing with Hong Haibo's opinion.

As the saying goes, you can't have the heart to harm people, and you can't do without the heart of defending people, and the Burrow needs some protective measures and self-defense weapons.

"Fire demon!" Hong Haibo and Xiao Zhen shouted out almost in unison. The most needed thing is naturally the fire demon, with the fire demon, they can do all kinds of experiments, without the fire demon, everything is equal to nothing.

"Well, I'll figure this out. Xiang Ze agreed very happily.

"Boss, where are you going to get the fire demon from?" Xiao Zhen expressed doubt.

"The main thing is that I don't have any friends outside, otherwise I can let them think of a way......" Hong Haibo always thinks about cheating.

"We can make it ourselves. Xiang Ze said he was confident.

The fire demon is one of the four great inventions of our Huaxia, which has been around since the Spring and Autumn Period and the Warring States Period, guess who invented it first?

That's right, it's the people who make alchemy! And Xiang Ze knows alchemy, so it's still his profession......

Of course, the technology of modern fire demons has become much more mature and sophisticated, but the most primitive components of fire demons are actually very simple, there are only a few things: saltpeter, sulfur, and charcoal. These are the three elements of the fire demon, and with these three substances, the fire demon can be created.

Needless to say, there is charcoal, there is also sulfur, and don't forget that the volcano is surrounded by many yellow rocks that contain a lot of natural sulfur.

This sulphur can be taken directly, but it can also be purified by a simple procedure. There is also saltpeter, and there are a few blisters on the grass to the west of the burrow, and there are no fish or shrimp in them, and the water is extremely bitter, because there is a lot of natural nitrate precipitated in it.

The reason why Xiang Ze knew this was because he had a lot of this kind of blisters near his home when he was a child in his previous life, and I heard adults say that there was nitrate inside, and every time it was cold, the water dried up, and all those white flowers like saltpeter were exposed.

It's very crystal clear, it's a bit like rock candy, but the taste is called bitter!

Don't ask Xiang Ze how he knows, who hasn't done a few stupid things when he was a child......?

With all three elements, is it still difficult to make a fire demon?

"Boss, I know there is saltpeter in those blisters on the west side, charcoal is easy to get, and clay is there, but we don't have sulfur. "Xiao Ai majored in biology, and chemistry is also a strong point.

She knew how to make a fire demon, but she didn't have sulfur, the most important ingredient in it.

"There's a lot of them on the volcano side, I can get some back. There's no rush to create a fire demon, what we need to do now is build a house......"

Xiang Ze's thinking jump is really weird enough, the fire demon said it is good, why do you want to build a house again?

Xiang Ze decided to build two more houses on both sides of the burrow, so that Xiaomeng and the fat man could all come back to live, I didn't expect the situation on the island to be so complicated before, and now it seems that it is not very suitable to live in a scattered manner, and it must be gathered together to take care of it.

Not only did he have to build a house, but he also had to remove all the fences in front of the yard and replace it with a stone wall to form a real courtyard, which was also for safety reasons.

It's a bit of a hassle, but Xiang Ze feels that it's worth it, he feels that he has neglected the security issue before, and now he must pay attention to it, he decided to clear the wilderness!

The boss gave the order, and everyone immediately carried it out. The fat man is still the old business, doing logistics, and ensuring everyone's three meals a day.

Xiang Ze is the commander-in-chief, he just gave a general order, and the specific implementation was discussed by Hong Haibo and Xiaozhen.

For these people, building a house was like having fun, and even before breakfast was finished, they drew a simple drawing to calculate the approximate amount of stone and wood needed......

They decided that the houses on both sides were also built of stone, so that there would be no hassle of burning bricks, and they would be relatively stronger. The problem is that the stone walls are not very strong when built with clay, and Xiao Ai says that she can find a way to configure the cement, but it is a bit troublesome.

There was limestone in the stone forest where they lived, which could be used to make lime, and with lime, they could add clay powder and some stronger sand instead of iron filings to make a lower grade cement, although it was low, but it was also many times stronger than clay!

After discussion, several people decided that it would be better to use cement, so that the wall could be built taller and stronger.

According to Hong Haibo's idea, he is also going to build a watchtower, which must have cement, although it is easier to build wood, but it is not reliable enough, in case of thunder and fire, it will burn directly, and even affect the burrow......
