His studio is just across the street from the Moston studio, but his studio has large floor-to-ceiling windows that allow the sun's rays to shine completely on his desk, and a chaise longue next to the floor-to-ceiling windows, on which he can lie down and think when he is not thinking.

"Alas~"

From time to time there were sighs in the room, and the old Longtuo, who was sitting on the side, looked at him with disdain, and his young age was like dying.

Of course, there is a reason why he has become like this, and now he has encountered a bottleneck, the design has been drawn, and I think that when he was weak, his mother wanted him to have another way out, and he also learned a lot of things, including learning to paint for a few years.

With his mental strength and muscle control improving now, it is relatively easy to draw a blueprint.

But in order to make a barrel, it is necessary to have a place that can reach 1535 °C, that is, a temperature that can melt wrought iron, and the mold for making the barrel is ready, but there is no place where the wrought iron, that is, wrought iron, can be melted.

"Lord Guardian, it's time for dinner. ”

The old Longnuo on the side stood up and urged him.

He nodded, he had no clue now, so he could only give up first.

The good meat steak on the table, exuding a unique aroma, and the black pepper on top of it is very fond of this person with a heavy taste, and this prince still prefers fruit juice in addition to tea, so there are few drinks such as red wine here.

"How's it going, my guardian knight, how did you sleep last night?"

He sighed, he had been working on the arquebus since he had arrived, and he hadn't had time to rest.

"Your Highness, do you know of anything that can produce high temperatures?"

With the mentality of giving it a try, he asked the prince, who liked to study strange things.

"Hmmm......"

The prince stopped eating, grabbed his chin with his hand and groaned for a while.

"Do you have to be outside?"

Morston looked up and suddenly asked.

"What does that mean, if you don't rely on external forces, can you use your own body to generate high temperatures?"

He looked at him with a smile, and suddenly felt that this guy was talking very interestingly.

"Don't you know?"

Morston looked confused.

"Under the control of spiritual power, the blood source can condense friction and then produce an extremely high temperature, otherwise what do you think the laborers here use to light the fire? But not everyone can afford to use the spirit stone. ”

Boom!

He startled the prince, who was putting food in his mouth, but with his excitement, Morston didn't pursue anything.

"I see!"

He touched his nose, he had never thought or thought about it since he came here.

I didn't expect that the solution to this problem was on me.

"Aha......"

Laughing maniacally, this is fantastic, the arquebus, as the prototype of the rifle, is definitely a milestone in the history of firearms, but what is its biggest drawback.

Is the operation complicated, no, no, no, its biggest drawback is the hemp rope, the hemp rope used to ignite the black powder, I heard that the soldiers in the past, they also had to carry two or three meters long, soaked in potassium nitrate or grease hemp rope, and once it rained, it was still a question whether the arquebus could be used.

Now that everything is settled, if the blood source can produce high temperatures, then even if the hemp rope is not needed, it can still ignite the black powder.

"How high can the temperature of this blood source be, Your Highness?"

"It varies from person to person, the high temperature of the blood source is related to the spiritual power and the upper limit of the blood source, in other words, the stronger the person, the higher the temperature generated, but ordinary people can also ignite dry wood, and the real ones who can melt the metal have to be those craftsmen, they have special techniques. ”

"Your Highness, can you please help me get a craftsman first, the craftsmanship doesn't need to be very high, just be able to melt wrought iron. ”

"There's a craftsman here, a friend of mine, who lives on the east side of the village, and that's a quirky fellow, and I can't necessarily call him over. ”

"Thank you so much, Your Highness, then please hurry up!"

"Do you want to go now? ...... now."

"Yes, that's right! Your Highness woke him up for me even when he was sleeping. ”

He was extremely excited, this new discovery was enough to keep him awake for a few days, and now it was only the beginning, and the ratio of materials was not clear, so it was enough to make a rough display.

His arquebus no longer needed arquebus, although it was not based on the wheel of flint and steel, but this discovery had completely eliminated a large part of the ills of arquebus.

He touched the sweat on his forehead, but he didn't expect that from the beginning of his gun-making business, the technology tree had begun to deviate.

However, as a person in this world, there is no need to imitate the predecessors to restore those retro firearms again, now he just needs to combine all the advantages that can be used.

The production of the arquebus was progressing by leaps and bounds, and with the help of the prince, the preparation of black powder had been completed, and it was made according to the perfect ratio of 10% sulfur, 15% charcoal, and 75% saltpeter in his memory.

Just as he was sitting at the workbench and thinking about how to change the arquebus, the door was violently kicked open.

A tall, muscular man walked in from outside the door, hesitated too well, and knocked his forehead on the door frame.

"I heard you kid has good things, and if I'm not satisfied, I'll screw your heads off. ”

The man rubbed his forehead, nearly three meters tall and strong muscles, causing him to squeeze in what he once thought was a Kodiak brown bear.

He glanced up at him, then lowered his head.

"Maybe I'm too tired and hallucinating. ”

He rubbed his eyebrows as he spoke.

"Boom!"

The man slapped the table in the face, nearly breaking the solid wooden table in half.

"Murston kid, say you have something fresh to play, hurry up and take it out. ”

The man's fleshy face really couldn't associate him with those elegant and lazy craftsmen, he looked more like a hooligan.

He shuddered in fright, and with trembling hands, he handed the structural diagram he had drawn in front of his eyes.

The man stretched out his big fan-like hand and took the parchment roll, cold sweat running down his head, for fear that he would accidentally tear this fragile thing to pieces.

At first, there was a sneer and mockery on the man's face, but when he saw the annotations and details behind him, his expression changed to surprise.

"Boy, you drew this?"

"Hmmm......"
