After Jun Rushuang came in, she saw Su Rui without makeup, as delicate and beautiful as a hibiscus out of the water.

After a busy day, seeing her, the mood seems to be better.

His furrowed brow furrowed slightly.

"I heard that you did a great job today." Jun Rushuang put the helmet under her armpit on the desk, and then removed her long sword and put it on the side of the helmet.

Su Rui hurriedly poured a cup of hot water for Jun Rushuang, the corners of his lips were slightly dry, and his face was covered with wind and frost, looking like he had just come back from outside.

Through the carved wooden cup, the heat of the water penetrated into Jun Rushuang's palm, and seemed to dispel some of the chill on his body.

"Have you eaten?" Su Rui pushed the two sweet potatoes in his bowl in front of Jun Rushuang, "I only have this here for the time being." "This is dinner from the head of the medical camp, two sweet potatoes and a little pickled vegetables.

Jun Rushuang's face was slightly pale, "Today's camp is busy, so there is nothing to eat." Are you still used to eating? I'll have someone bring something else in a moment. ”

"Don't." Su Rui immediately waved his hand and refused, "I don't want to make anything special, other soldiers can eat it, I can eat it, you don't have to worry about me." By the way, why did we lose so badly today? Is it because we have fewer people? ”

When Su Rui was treating his injuries, he listened to them one after another about the battle situation on the front line.

"Not less. It's just that our Dajin has always relied on city defense, mainly infantry, supplemented by cavalry, and our cavalry is also light cavalry, and Rouran is heavy cavalry. Jun Rushuang sighed when she said this, "It's not that our soldiers are not brave in battle, but that we are not as good as others in terms of weapons or other things." ”

"Weapons?" Su Rui's brows furrowed slightly, and his gaze fell on Jun Rushuang's long sword.

"Our weapons will be brittle in such bitter cold places." Jun Rushuang frowned and said, he drew his long sword, and flicked it with his fingers, and the sword body made a metallic buzzing sound.

"Are our weapons made of pig iron?" Suri asked.

Jun Rushuang nodded, "Our Dajin's weapons have always been like this. "Although Daikin's craftsman skills are unique in the world, he has always emphasized literature over martial arts, and all the skills of craftsmen have been used in the production of handicrafts, and as for weapons, they have never been developed. Suri is clear about that.

"Then it's no wonder." Su Rui nodded suddenly, she pointed to Jun Rushuang's weapon and said, "Pig iron contains a lot of carbon, although pig iron is relatively hard, but it is very brittle and easy to break. This is especially true in cold places. ”

"That can be solved?" Jun Rushuang's eyes lit up and asked.

"Yes, yes, but it's very troublesome." Su Rui scratched his head, "If we want to make the weapon not damaged, we must improve the material, and we can no longer use pig iron to forge the sword, but use steel to forge the blade to increase the strength and toughness of the blade." ”

Although Jun Rushuang doesn't understand the concept of toughness, he is a very smart person, what Su Rui said is exactly the same, the swords here are cast, not forged, although there is only one word difference, the essence is very different.

"Your consciousness says you want to make the blade like the Shining?" Jun Rushuang's eyes lit up immediately and asked.

"Yes." Su Rui patted his head, "That's what it means." Do you know the person who forged the Shining? "I don't know who forged the Shining, but the thin, resilient blade was clearly made of a good steel.

"But the man who forged the Shining is no longer alive." Jun Rushuang's eyes dimmed again, and the flame of hope that had just been ignited was forcibly extinguished. "He only created a shining spirit in his lifetime."

In this way, Su Rui was also a little discouraged, she saw that Jun Rushuang was slightly lost, and she couldn't bear it, she comforted her, "It's okay, as long as we can make one, we can make countless ones." Even if you can't reach the realm of Shining, you can at least create the kind of weapon that should not be broken. ”

"Really?" Jun Rushuang asked.

"Why not?" Su Rui raised his eyebrows, "It's also all about making weapons, and if someone else makes it, we will make it!" ”

Jun Rushuang was also slightly heated by the confident Su Rui, yes, the former can be made, there is no reason why they can't make it. It's just that time is tight now, and I don't have time to study it.

"Do we have a blacksmith in our barracks?" Suri asked.

"Of course, there are, a lot of blacksmiths." Jun Rushuang nodded, when the army marches and fights, there will naturally be craftsmen accompanying him.

"Okay, I'll go find some paper and pen in a while, I probably remember a little bit of the process flow chart of steelmaking, I'll write it down, you find some good masters to study it, I believe there is no difficulty that we can't overcome." Suri laughed.

When she was sick, there was a university professor in the next room who was engaged in steel research, and that professor had told Suri some simple tips on steelmaking.

Suri has a good memory, and sometimes he would go over to help the professor transcribe his autobiography, so he came into contact with some. She learned it in a mess and was very miscellaneous, and she thought it was useless, but she didn't expect it to be used here.

Jun Rushuang and Su Rui are both mothers-in-law, the two discussed for a while, hit it off, that night, after Jun Rushuang left, he ordered someone to send pen, ink, paper and inkstone.

Su Rui did not procrastinate, and immediately relied on his memory to write down the process of steelmaking.

There are places where she also remembers vaguely, she can only honestly mark out, many things need to be explored step by step, as long as there are old craftsmen, the efficiency of doing things will be improved a lot, after all, Su Rui's knowledge is only in books, it is dead, and what they have mastered is real technology and practice.

Although they don't have a theory, they have been with iron all their lives, and I believe that as long as they have someone to dial it, it is not difficult to make steel, and it is definitely not as good as the high-quality steel of the Shining, but it should still be possible to deal with the Rouran people.

However, the ideal is always far from the reality, and Su Rui handed over a complete set of flow charts, only to find that most of those craftsmen were illiterate and could not read at all.

Su Rui was embarrassed in an instant, she wanted to explain it herself, but Jun Rushuang was afraid that Su Rui would always be seen to be a woman's identity if she always came into contact with those rough people, so she was not allowed to go. She could only wait for Jun Rushuang to find her when she was free, she explained them to Jun Rushuang one by one, and then Jun Rushuang went to tell those craftsmen.

~~~~ The dividing line ~~~~~

Take a leave of absence, I'm busy today, I really can't write more, I'll make up for it tomorrow.
