At first thought, Roland left the third border town and immediately went to the ammunition factory.

Although Anna is not in winter at the moment, if his vision is correct, this part of the transformation can be done with existing technology alone.

Or, in other words, it has the value of mass production.

In the guard's cluster into the factory, the unprepared workers suddenly fell to their knees, the scene was full of surprise and excitement.Looking at everyone's feverish eyes, Roland realized that his behavior may be too impulsive, but since he has come, he will be wrong, and turn the test into a condolence inspection trip.

It was hard to get the energetic workers back to work, and he immediately ordered the person in charge, "Call the most skilled director in the factory, I have something I want to try."

“Yes, your majesty!”

The principle of tracer is not complicated, in simple terms, it is to empty the solid warhead, and fill in the luminous agent, the combustion agent and the delay gunpowder, and then use the tailpipe and aluminum foil sealing.When the bullet is fired, the gas will break through the foil and ignite the delay gunpowder until the luminous agent is burned, and finally a bright trail is formed.

For the future generations of all kinds of chemical industry, this is just a problem of adding a production line, but replacing the industrial projects are extremely uneven Winterfell, which is obviously a headache.The luminous agent is generally a mixture of strontium nitrate, magnesium aluminum powder and barium peroxide, which means that if you want to mass produce tracer bullets, you must first conquer the industrial production line of these compounds.And at what level the chemical industry of his own territory is, Roland naturally knows - until now, the Ministry of Chemical Industry has not dared to say that it will meet the supply of machine gun ammunition for the First Army, let alone other.

The person in charge quickly found a craftsman - some to his surprise, the other party is not a gray hair, trembling old man, but a young adult of about twenty-five or six years old.He got down on one knee and saluted like a knight, “Your Majesty, what can I do for you?”

Roland then reacted, yes, the winter city has entered the era of mechanical production, the younger generation with more learning ability is becoming the main force of the industrialization wave, which is also a difficult sight to see in the handicraft workshop - the speed of technological progress beyond the advantages brought by age, in the face of new production tools, the past experience is no longer applicable.

Now think, most of the busy people in the factory are in their twenties and thirties, thinking that they have taken on key positions, the future of Grey Fort is really worth looking forward to.

Roland nodded with satisfaction, "I want to add something new to the bullet, and you can do as I say."

His idea is very simple, since the "stone monument" will emit a dazzling light when it is violently deformed, so as long as the impact of gunpowder gas, it may be possible to achieve the same tracer effect.

Its specific principle is similar to the stamping machine - in the warhead to cut a gradually tightened gourd mouth, the bottom filled with a thin stone tablet slice, when the bullet is fired, the expansion of gas will directly squeeze the slice into the gourd mouth.Due to the presence of the middle bayonet, even after the bullet is out of the chamber, the slice cannot be restored to its original state, which is equivalent to being in a shrinking state, so as to continuously emit light until the electrical potential is exhausted.

A few words were explained, for convenience fully understood his intentions, and took a sip to come down.

Just one day later, a verification report was delivered to Roland’s desk.

It turned out that the method was indeed feasible, and after many attempts, the 20 rounds of successful transformations could see obvious flashes, and the barrage left a clear visible light mark in front of everyone.

He couldn’t help but be excited!

For a long time, the night battle that does not see the landing point of the shooting has always been a major weakness of the fortressing tactics of the First Army, even if it is used with lighting bombs, it is still difficult to achieve the shooting level during the day under yellow light conditions.In addition, if the machine gun is put on the plane, the problem will only be more prominent - even on cloudless sunny days, the pilot may not know where he put the bullet.If the instructions can be achieved in such a simple way, it will undoubtedly be of great benefit to the upcoming battle of God's will.

Moreover, the traditional tracer bullet due to the continuous consumption of the luminous agent, the weight and center of gravity will change, and eventually lead to the deviation of the ballistics, so at the beginning of its appearance, there is also a "the tracer bullet hit, which means that other bullets are not hit" argument.The use of "stone" fragments that will not be consumed as an indicator light, the performance is better than traditional methods - as long as the body is slightly longer, the flight characteristics of the new tracer can be almost the same as the normal bullet.

The only question remains is how many “stone monuments” are available in the far south.

...

A week later, two of the discoverers of the desert ruins arrived at the shoal harbor.

In the living room, Roland re-inquired about the wonders they had found under the water hole.

The two men’s answers were broadly in line with what was in the report — they were only a few hundred meters away from their explorations before they encountered the iron-clad giant scorpion, and nothing was known about what was behind the so-called “stone wall.”

In other words, the “stone monuments” they see are probably only a small part of it.

After all, according to the murals to infer that the blood can be gathered into the river of the body, the number should not be in the minority.

In addition, Shamin Sinbadi's description makes him very concerned, that is, the environment in the cave is like Yinchuan Oasis, and even the rumored extinct gods make flowers.

If the vast grasslands of the past have really degenerated into deserts because of the departure of the three messengers, then the underground of the endless cape should be no exception.

Maybe there is a deviation in the rumor itself, or there is another hidden opportunity.

He couldn’t wait to dig up the desert and take a look.

After asking about the situation, Roland left the fjord man alone.

"Your diving attire is interesting, and the ruins you find are enough to remember the annals of history," he slowly took a sip of tea, "to be honest, it really surprised me to see that you can use the steam engine in the new invention - to know that most people buy it and use it is difficult to even use it, without the technical staff sent by the factory to guide, they can only stand on the side and make a change."With this ability alone, half your foot has set foot on the podium of a lifetime of honorary explorers.”

“Thank you so much,” Rex said excitedly, “it took me six months to figure out how to control it.”I can give you priority if you need it, and the price is no problem at all—”

"No, you misunderstand, I don't need your diving attire," Roland smiled slightly. "Actually, I can do better if I want to."

Rex blinked, not seeming to expect such a response.He grinned awkwardly, as if trying to squeeze out a smile, “Your Majesty...”

Roland interrupted him directly, “You may think I’m bragging, but it doesn’t matter.”What I really want is a wonder."

The other person couldn’t help but froze, “I... don’t understand what you mean...”

"I know what you want to prove, and I can help achieve that."Roland bluntly said, "There are two kinds of wise people in the world: stargazing and alchemy - let alone the former, I think there is no essential difference between what you do and alchemy, but create new things for human beings."So why not think of the strange object as the third kind of wiser learning, and establish a trade association with it?”

Rex's breathing suddenly rushed, and he suddenly realized the meaning of these words - if they were used by others, he would only feel nonsense or even ridicule.Compared with the famous alchemist association and stargazing association, the wonder club is not worth mentioning at all.But the king of the castle is different, and in his fame and voice, this is not a possibility.

He swallowed his mouth and felt his voice hustle, “So... what’s the cost?”

Since the other party intends to help the strange object to correct the name, it is impossible to not have the figure.

“All of this.”

“What...?”

"Cough, no, I mean, you're going to work for me."Roland cleared his throat, "relocating to Winter City and become part of the gray castle."All research results belong to me, including the right to sell and use.And you will receive honor and wealth, and a better environment for research.”

“I...” Rex didn’t know how to answer for a moment.Although the things they have created are despised and criticized, they are like their own children, so if they are handed over to others, most of them are afraid that most people will not agree.

"I know that you need to think seriously, and you should go back to the resting place and think about it."Roland stood up and pushed the book beside him, "Give me an answer in three days."

“Son, this is it...” Rex asked, lifting the book.

"The reward of your discovery."He raised his mouth and answered.
