Second Sister Nongmen has space

Chapter 500 Secret Weapon
Go, of course I want to go, this is the treasure I have been thinking about for a year!

In the scientific research institute next to the city lord's mansion, Song Liyun first saw the palm thunder that was successfully developed earlier!

The pig iron cylinder is made of leather, oval in shape, with a pressure ring and safety lock, exactly the same as the grenade in her memory.

Mr. Yu said happily: "Young Madam, as long as these palm mines are thrown, they can explode in five breaths.

We have tried it, and it will be scratched by iron sheets half a foot around the fried point! "

He tried it with a sheep tied to the side, and the grenade exploded. Although the sheep was still alive, its body was covered with wounds from iron plates, dripping with blood, and finally died after bleeding out.

Song Liyun calculated silently in his heart, and smiled on his face: "Mr. Yu has worked hard. With the current speed, how many pieces can you make in a day?"

Speaking of which, these grenades are not as lethal as arrows.

The explosion range of the grenade is half a zhang, which is the distance between two horses.

Moreover, the human throw is only ten meters, and it still scratches.

The range of the bow and arrow is ten feet, which is 30 meters, which is three times that of the grenade. Coupled with the speed of the horse, it is almost instantaneous.

Moreover, the grenade has a ten-second delay, one-on-one, the grenade may not be able to win.

However, the ruler is short and the inch is long, and each has its own splendor.

The advantage of thermal weapons is that they have low technical requirements for users.

A mature archer needs ten years of training, coupled with superb riding skills, he must be one in a million.

A qualified thrower only needs three training sessions, and he can even grab a bold one and hit the top.

The rest is just a matter of production costs.

As long as there are enough of them, it can be used as an elite teacher even if children throw grenades to bombard them.

Mr. Yu stretched out five fingers: "Young Madam, we can make five pieces a day, and right now, there are fifty pieces in the warehouse!"

Song Liyun clicked his tongue, the number is a bit small, but as long as he uses it well, he can still be invincible.

Since the discovery of iron ore and coal mines three years ago, Zhao Tinglei sent a large amount of gunpowder to blast the mountain to open mines.

Song Liyun's eyes also fell on the gunpowder.

In this era, the use of gunpowder is in fireworks, fire clips and explosives.

When blasting mountains and rocks, first let the stonemason use a chisel to open a cave, fill it with gunpowder, and then ignite the fuse.

There is no standardized construction, everything is based on experience, it is very dangerous, and it will hurt people if you are not careful, so it is not used unless it is a last resort.

Song Liyun asked people to develop better gunpowder and grenades.

As for the guns...that's impossible, without fine iron and precision machinery, even if they are produced, they will explode, that is, fire sticks.

This time Yu Lao Wan Youyou asked her to watch the experiment not a grenade, but two landmines.

Made of porcelain, green glaze is applied on the outside, gunpowder is inside, and the bamboo tube can detonate the explosion.

Because of its shape like the fruit of terrestris, it is also called fire terrier.

In the cart that Lin Qingyuan came over this time, except for some basic living supplies, there were several carts of specially made pottery pots and gunpowder bamboo tubes.

After a month or so of repeated configuration, it has now been completed.

In a depression outside Mida City, Mr. Yu had someone carefully bury the ceramic pot in the pit, and cover it with soil and stones.

The sheep were driven and trampled over, and there was no movement at the place where the clay pots were buried.

Song Liyun looked at Mr. Yu with a solemn expression.

Mr. Yu explained: "The flock is not heavy enough, these mines are aimed at people and horses!"

Next, a group of enraged bulls ran past, making two bangs.

Hundreds of meters away, Song Liyun clearly saw the result through the telescope. The scene was very bloody, which also meant success.

The people under Mr. Yu rushed over quickly to inspect the two cows that had been blown into a pile of rotten meat.

Song Liyun asked Mr. Yu: "How much can landmines make every day?"

Elder Yu blinked and didn't speak, Wan Youyou, who was hiding in the ditch with his son in his arms, said, "I'm fine!"

Mr. Yu said decisively: "There are ready-made clay pots and bamboo tubes, as long as Wan Niangzi's gunpowder ingredients can keep up, dozens of them can be made in a day!"

"it is good!"

Song Liyun's heart was settled, and with these things, his stable life would be more secure.

Most of the merchants returned to their hometowns, and the city was quite quiet, only a few sporadic horses ran past.

The only thing that is lively is the big windmill by the river.

Now the surface of the river has begun to freeze, and under the impetus of the strong wind, the non-stop axles hit the water surface more forcefully, pouring water into the deep underground tanks and flowing into the city.

Snowflakes and splashing water mist condense into ice shells on the surface of the tall windmills, gather into ice hangings and ice edges, and under the reflection of the sun, they are colorful and extremely gorgeous.

Compared with Hongqiao in summer, it is a magnificent scene, attracting people from all tribes to come to worship again.

Wan Youyou was so busy in the scientific research institute that he never touched the ground, while Song Liyun was playing chess and studying with the maids in the Nuan Pavilion.

Mrs. Yun and Yuquan took care of Mrs. Wan's child while making underwear for Song Liyun.

Everything looked stable and peaceful, but Song Liyun was a little absent-minded.

Zhao Tingduo hasn't replied yet.

Although sometimes it is a good thing not to have faith, but swords have no eyes on the battlefield, and those Di people also have strange things.

"Ma'am, you lost!"

Xiao Ye Zi blushed, and she won another game of chess.

Song Liyun looked down and saw that he had accidentally surrounded a piece of white stones to form a deadlock.

"Haha, Xiao Yezi is getting better and better now, I'm sleepy, I'll play again tomorrow!" Song Liyun put down the chess pieces and said.

"Yes, young lady rest first!"

Xiao Ye Zi cleaned up the chessboard, and Yu Quan next to him put down his embroidery and came over: "Young Madam, do you want to lie down for a while?"

"No, Yuquan, get your cloak here, I'll go for a walk on the street!" Song Liyun wanted to get up.

Yuquan helped her up: "Young madam, it's snowing heavily today, so don't go, if anything happens, let the stone pass the message!"

Yuquan didn't lie to her. Ever since Lin Qingyuan's caravan left, it has been gloomy with occasional snowfall, and it has become even worse in the past two days.

Song Liyun lifted the curtain to look, and said in a low voice: "There is news from the caravan, where are they?"

The big caravan has left Mida City for five days, and it should have crossed the Zhabu River as usual, and it only takes two more days to reach Hecheng.

It's just that the weather is not good after departure, and heavy vehicles are slowing down. When crossing the pontoon bridge of the Zhabu River, I'm afraid it will not be too smooth.

Yuquan shook his head: "Shishi didn't send the letter!"

Song Liyun had things on her mind, she still wanted to go to the scientific research institute, otherwise she would always be in a panic.

Yuquan didn't dissuade her this time, but took a lamb's wool cloak and put it on her, wrapped a copper stove for warming her hands, and then walked around the veranda.

Unexpectedly, as soon as he left the second door, he saw Shi Shi, who was in charge of reporting the news, running in with his clothes scattered. He was obviously in a hurry, and he didn't see Song Liyun standing in the corner.

"Brother Shitou, why are you panicking? The young lady is here!" Yuquan called out to him.

Hearing the sound, Shi Shi made a sudden stop and nearly fell down. When he turned around and saw that the young lady was really there, he quickly climbed over the corridor and ran over.

"Young Madam, something happened to the caravan!" His voice was urgent.

Song Liyun's heart sank, but she still said calmly: "Don't panic, talk to me in the study!"
