Go, of course I have to go, this is the treasure that I have been thinking about for a year!
In the scientific research institute next to the city lord's palace, Song Liyun first saw the palm thunder that had been successfully developed in advance!
The cast iron barrel was made of leather, oval in shape, and equipped with a pressure ring and safety pin, exactly like the grenade she remembered.
Mr. Yu said happily: "Young madam, as long as these palm thunders are thrown out, they can explode in five breaths.
We have already tried it, and half a foot around the explosion point will be scratched by iron pieces!"
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 cut by iron pieces, and it was dripping with blood. In the end, it died after all the blood flowed out.
Song Liyun silently calculated in his mind, with a smile on his face: "Thank you for your hard work, Mr. Yu. At the current speed, how many 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 foot in radius, which is the distance between two horses.
Moreover, the human-powered throw was only ten meters and still resulted in scratches.
The shooting range of the bow and arrow is ten feet, which is thirty meters, which is three times that of the grenade. Coupled with the speed of the horse, it can reach almost instantly.
Moreover, the grenade has a ten-second delay, so one-on-one, the grenade may not be able to win.
However, a ruler is shorter and an inch is longer, 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, no matter what, he has to be one of the best.
A qualified thrower only needs three trainings, and he can even hit anyone who is brave.
The rest is just a matter of production costs.
As long as there are enough of them, even if you let children throw grenades and blast them randomly, they can also be used as elite soldiers.
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 was a little small, but as long as it was used well, it could still be invincible.
Since the discovery of iron ore and coal mines three years ago, Zhao Tinlei has sent a large amount of gunpowder to blast mountains and open mines.
Song Liyun's eyes also fell on these gunpowders.
In this era, gunpowder was used in fireworks, fire bombs and mountain explosions.
When blasting rocks, first let the masons use chisels to dig out the holes, fill them with gunpowder, and then light the fuse.
There is no standardized construction and everything is based on experience. It is very dangerous and can hurt people if you are not careful. Therefore, it should not be used unless it is absolutely necessary.
Song Liyun asked people to develop better gunpowder and grenades.
As for guns... that won't work. Without refined iron and precision machinery, the chambers would have to explode even if they were produced. That would be fire sticks.
This time Yu Lao Wan Youyou asked her to see the experiment not with grenades, but with two landmines.
Made of porcelain, with celadon glaze on the outside and gunpowder inside, the bamboo tube can detonate explosions.
Because it looks like a thorn fruit, it is also called fire tribulus.
The cart that Lin Qingyuan came over this time contained several carts of specially made clay pots and gunpowder bamboo tubes, except for some basic living supplies.
After a month of repeated configuration, it is now complete.
In a depression outside Mida City, Mr. Yu asked people to carefully bury the ceramic jars in the pit and cover them with soil and stones.
The sheep were driven and trampled over, but there was no movement where the pots were buried.
Song Liyun looked at Mr. Yu with a solemn expression.
Mr. Yu explained: "The sheep are not heavy enough, these mines are aimed at people and horses!"
Next, a group of irritated bulls ran past, making two "boom boom" sounds.
Hundreds of meters away, Song Liyun clearly saw the results through the telescope. The scene was bloody and meant success.
Mr. Yu's men 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 mines do every day?"
Mr. Yu blinked and said nothing, while Wan Youyou, who was hiding in the trench with her son in her arms, said, "I have no problem there!"
Mr. Yu said firmly: "There are ready-made clay pots and bamboo tubes. As long as Wan Niangzi's gunpowder ingredients can keep up, we can make dozens of them a day!"
"good!"
Song Liyun was convinced that with these things, his stable life would be more secure.
Most of the merchants returned to their hometowns, and the city suddenly became quiet, with only a few scattered horses running by.
The only lively thing is the big windmill by the river.
Now that the river surface has begun to freeze, the non-stop wheel axle, driven by the strong wind, hits the water surface more powerfully, pouring the water into the trough buried deep underground and flowing into the city.
Snowflakes and splashing water mist condensed into ice shells on the surface of the tall windmill, gathering into ice hangings and ice edges. Under the sunlight, they became colorful and gorgeous.
Compared with Hongqiao in summer, it is a grand scene that attracts people from various tribes to come again to worship.
Wan Youyou was busy in the scientific research institute, while Song Liyun was playing chess and studying with the maids in the Nuan Pavilion.
Lady Yun and Yuquan took care of Lady Wan's children while making undergarments for Song Liyun.
Everything seemed stable and peaceful, but Song Liyun was a little absent-minded.
Zhao Tingduo has not replied yet.
Although it is said that sometimes having no faith is a good thing, but on the battlefield, the sword has no eyes, and there is something strange about those Di people.
"Madam, you lose!"
Xiao Yezi's face turned red, she won another game of chess.
Song Liyun lowered his head and saw that he had accidentally surrounded a field of white stones into a dead end.
"Haha, little Ye Zi is getting more and more powerful now. I'm sleepy. I'll play again tomorrow!" Song Liyun put down the chess pieces and said.
"Yes, young madam, rest first!"
Xiao Yezi put away the chessboard, and Yuquan next to him put down his embroidery and came over: "Young lady, do you want to lie down for a while?"
"No, Yuquan, come here with your cloak and I'll go for a walk on the street!" Song Liyun wanted to get up.
Yuquan supported her: "Young madam, it's snowing heavily today, so you'd better not go. If anything happens, just let Shitou go over and tell you!"
Yuquan didn't lie to her. Ever since Lin Qingyuan's caravan left, it had been gloomy and occasionally snowy, and it had gotten worse in the past two days. The walls on the ground were piled white, and the cold wind made the bricks and stones whimper.
Song Liyun opened the curtain, took a look, and whispered, "Has there been any news about the caravan? Where are they?"
The large caravan has already left Mida City for five days. As usual, it should have crossed the Zabu River and only needs two more days to reach Hecheng.
However, the weather was not so good after we set off, and the heavy traffic was moving slowly. Crossing the pontoon bridge on the Zabu River might not be too smooth.
Yuquan shook his head: "Shitou didn't send a letter!"
Song Liyun had something on her mind. She still wanted to go to the scientific research institute, otherwise she would always feel overwhelmed.
Yuquan did not dissuade her this time, but took a large lamb's hair cloak and put it on her, and wrapped it with a hand-warming copper stove, and then walked around the verandah and walked out.
Unexpectedly, as soon as he walked out of the second door, he saw Shi Shi, who was responsible for breaking the news, running in with his clothes hanging. He was obviously in a hurry and didn't even 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, Shitou stopped suddenly and almost fell down. He turned around and saw that the young lady was really there, and hurriedly climbed over the corridor and ran over.
"Madam, something happened to the caravan!" His voice was urgent.
Song Liyun's heart sank, but she still said calmly: "Don't panic, go to the study with me to talk!"
