Pastoral lucky girl's counterattack

Chapter 427 Experiment
With saltpeter and sulfur, Qiu Laifu's homemade gunpowder plan also began.

The original formula for gunpowder was saltpeter and sulfur, plus charcoal.The most rare of these three raw materials is saltpeter. Sulfur is very common, almost available in drugstores. As for charcoal, Qiu Laifu processed it on the spot, and had someone burn some charcoal in the village and sell it to her.By purchasing charcoal from the villagers, on the one hand, it can also replenish these villagers and give them a little extra income.

In the following days, Qiu Laifu handed over the affairs of the river course to Cao Zhiyang, and she took Xia Houyu to experiment with the preparation of gunpowder.Xia Houmo was assigned by him to assist Lin Zidan again.Qiu Laifu didn't want too many people to know about gunpowder.So only Xia Houyu was left to help her.

Homemade gunpowder is a very dangerous thing. Although he knows the recipe, he has never made it himself, so Qiu Laifu is not worried about moving this thing to the Qiu family's yard, but rents this remote and dilapidated big yard.

Now she is experimenting with gunpowder in this yard every day, and Xia Houyu helps him. Anyway, Xia Houyu knows many of his secrets, and doesn't care if he knows more about it.

After several failures, the formula ratio of gunpowder was finally tested.However, its bursting strength is another big problem. If it is made of ordinary bamboo tubes, the bursting strength will definitely not be great. Nowadays, the best material can only be iron cans.

Qiu Laifu drew two iron cans for Xia Houyu, and asked him to send them to the workshop in the courtyard of the Qiu family, and asked the blacksmith to make three sets for him.

Xia Houyu took back two samples that afternoon.One tubular and one spherical.The diameter of the tube is about three centimeters and the length is ten centimeters.Spherical, about eight centimeters in diameter.These two shapes, Qiu Laifu refer to modern primitive grenades and grenades.

On the second day, Qiu Laifu found the steep slope of the river in Changku Town, which is now dry again.

As long as the water level in front drops a little, the river will dry up. The reason is that the slope of this section is too high, so that the river bed is high and the water cannot flow.

This sloping land is full of stones, exposed stones, so there are no crops and no one lives in this area.

Qiu Laifu chose to do experiments here, it couldn't be better.

After nightfall, the two came to the selected place, took out their daggers and dug up on the hard stone of the river bed.

She needs to dig a hole first, and then bury the grenade or grenade in it.

Xia Houyu watched her stabbing the stone with a dagger, and felt very distressed by that dagger. What did she use this good thing for?It's just a waste of a good thing.

Qiu Laifu dug for a while and only managed to dig a foot deep.Watching this progress feels decadent and tiring.So he handed the dagger to Xia Houyu and asked him to continue digging.

Xia Houyu held the gleaming dagger, really reluctant to do it.But Qiu Laifu's eyes kept urging him, and he couldn't harden his heart and use the dagger to stab the stone hard.

Unexpectedly, without much effort, he poked the stone a few inches deep.It turned out that this dagger was so sharp, no wonder Qiu Laifu was able to poke stones with it smoothly.

But Xia Houyu was very sad in his heart, he was reluctant to give him such a good thing, and it was a pity to spoil it like this.

Xia Houyu felt sorry for the dagger in his hand, but Qiu Laifu didn't know it.At this time, I feel that I have enough rest.Picking up another dagger, he started digging a hole a foot away from Xia Houyu.

Xia Houyu was so greedy when he saw it, he said to Qiu Laifu, "You are really handy than your hands. Give me a hand!"

Qiu Laifu didn't even lift his head, and said generously, "If you like it, I'll give you the one in your hand, and just dig a hole this deep." Qiu Laifu made a distance of one meter with his hands.

Xia Houyu looked at it and nodded.Now he is more motivated, this dagger is so easy to use.The master gave it as he said.If he didn't have something to do, he would definitely want to jump up right now to vent his joy.

The two dug for about an hour before it was considered complete.Qiu Laifu carefully buried the homemade grenade in the deep pit.The grenade has a long fuse, which is specially left so long for the convenience of ignition.

Xia Houyu also followed what Qiu Laifu did, and buried the grenade in his hand in the hole he dug.Worried that the fuse would be broken, some sand was directly covered on it, and the grenade and grenade were buried, and the fuse was still exposed to the ground about a foot.

Both of them retreated more than ten meters away.Qiu Laifu scanned the surroundings with his consciousness again, and there were indeed no living creatures in this area. Qiu Laifu attacked with a fire attack, and a small fireball flew towards the two fuses. The fireball rolled past, and the two fuses sizzled It burned up.

Because it was the first experiment, Qiu Laifu didn't know how wide the coverage of this effect was, so he took Xia Houyu and quickly flew away from the scene with light work. He flew hundreds of meters away before hearing "Boom!" "Boom!" !” Two loud bangs.Accompanied by the loud noise, there was a burst of shaking.

After the ground shook and the mountains shook, Qiu Laifu looked back and saw that the place where they buried the explosives had been blown away, and many rocks were still rolling down the slope.

When the rocks stopped rolling, the two came to the blasted place again. Qiuqiu Laifu looked at the blasted hole and shook his head, not very satisfied with the result.

However, Xia Houyu who was beside her was pale and pale with shock.There was a storm in my heart.too terrifying.The effect is horrible.

The place where it was blasted was fully dented more than two meters deep.The diameter of the exploded area is more than three feet.

Now he is very confident that this master can open this ramp!To be able to make such a powerful thing.It only takes a few cannon shots to complete.He can even believe that this steep slope can probably be flattened, right?
There is no such a steep slope.The river water did not flow smoothly into the original river channel.

If it's just for circulation, then just blow up this steep slope.

But she didn't do this, but first repaired those rivers in order, and then came here.

As long as you think about it for a while, you can understand the purpose of these. On the one hand, a large piece of wasteland on the edge of the river has been developed, turning this piece of wasteland into a treasure land.On the other hand, the opening of this river channel has driven the economy of the entire Zhaoyang Prefecture.

These actions are entirely for the benefit of the people.His little master is not simple.People are not small to be careful, this is righteousness!

Qiu Laifu is not as sentimental as Xia Houyu, she only sees that the effect is not ideal, but there is no need to strengthen it, because the effect is already shocking, if it is strengthened.Maybe it will attract someone's attention, and she doesn't want to be in trouble.
