The news of the appearance of the demon and the defeat of the evil beast by Rafa's new weapon quickly spread in Icefield City, and for a while, there was no one in the entire Icefield City who did not talk about it, some people said how powerful the demon was, and others said that Rafa's firearms were even more powerful...... Although many people in the city saw the bright light and heard strange cries, the actual situation was still known only to the knights who were present at the time.

When they first learned the news, people were worried at first, they were afraid of the appearance of the demons that the knights said could move without heads, but after thinking about it, His Highness Rafa could solve any difficulty, and these demons should be nothing, so they gradually relaxed.

However, Rafa himself knows that with his current strength, I am afraid that there is no way to stop those demons without relying on the abilities of the witches.

"Alas, it looks like I'm going to hurry up my practice. ”

At the end of the day of wandering around Icefield with Freya, he began to sit on his bed, gradually entering a state of steady, after more than a month of deep sleep, he felt like he had to pull off a lot of homework.

"Mingtai, True Spirit, Body Flame, Dustless, Void Combination, True One, Return to the Ruins," after a while, a string of familiar words appeared in his mind.

"I didn't expect that the cultivation star would be hidden for more than three months, and this is just getting started. ”

"Seven major realms, five small realms on each floor, now I have just ...... on the first floor of Mingtai" Sitting on the bed, the window was closed, and the hair and clothes on his body fluttered without wind, "Fortunately, Xingyin is magical enough, and there is a never-ending sea of qi like a whirlpool, which is equivalent to allowing me to practice all the time, although it is not as fast as deliberate cultivation, but it is enough for me." ”

After three months of intermittent and unintentional cultivation, the whirlpool in his sea of qi had reached the width of a large well, and the spiritual power flowing in the limbs and hundreds of bones was gathering here in a steady stream.

"If the whirlpool of the sea of qi reaches the size of a storm, I should be able to single out a city, right?"

Rafa quickly condensed his spiritual power while thinking, because the memory of his previous life cultivation was still there, so he was also very handy in cultivating Xingyin Decision, and the spiritual power like a flowing cloud flowed obediently in his body, and he entered the realm very quickly.

It's strange to say, since he was shot in a coma for more than 20 days, and now after waking up, his cultivation has accelerated a lot, as if a certain obsession in his heart has been lifted, making his heart feel unprecedentedly open, just in the middle of the night, the effect is even better than the previous three months combined, is it a sleep and a sleep?

"Huh?"

Rafa, who has been in a state of concentration, has a very clear perception of his surroundings.

Not long after midnight, a slightly heavy footstep stopped at his door, as if it was a vigil for him.

As soon as he heard it, he could hear that it was Audrey.

He knew that Audrey was still haunted by the last attack he had been attacked, and that she was afraid that the Assassins would show up again, so she wished she had stayed by her side all day and all night.

"What a silly girl. ”

Rafa exited the settling mode, shook her head helplessly, and stepped out of bed.

In the silence of the night, he could clearly perceive that when Audrey appeared, Felicille next door also got out of bed, but when he got up, Feliciel seemed to be back under the covers.

"I didn't expect so many people to care about me. Rafa was suddenly moved.

"Your Highness!"

The door suddenly opened, and Audrey panicked.

"What are you doing?"

In the cold night, Audrey was wearing a simple knight's armor, and her hand was always pressed on the sword, although she was wearing a robe, but the cold air flowed through, and her face was still a little white from the cold.

"I ...... Feel free to wander around. Audair knew that if she had come to the vigil, Rafa would have let her go, so she had to make up a somewhat clumsy lie.

"......" stared at Audrey's dodgy eyes for a moment, and Rafa felt that she would not listen to her again, "Come in." ”

"Huh?" Audrey was taken aback.

"I'm already out of bed. Rafa explained.

"Oh. ”

Inside, Rafa sat down on his desk and pointed to the big bed, which didn't seem to have been touched at all, "Let's sleep for a while." ”

"I'm not sleepy. Audrey sat upright on the edge of the bed with her sword in her arms.

"Stubborn girl......" shook his head with a smile, he stopped looking at Audrey, turned his head and took out a clean drawing, and began to conceive of it with the bright moonlight that happened to shine on his desk.

Due to the appearance of evil beasts and demons, he had to seriously conceive of weapons more powerful than firearms.

"Now that gunpowder can be mass-produced, it shouldn't be difficult to make something as uncomplicated as mercury leilate. ”

Mercury thunderate is one of the indispensable key things for improving ammunition, and its role is to be used in the ignition device or detonator of new weapons, such as to make simple grenades, fire detonators, artillery, mines, mortar ammunition, and so on......

If the appearance of gunpowder brought a fire to the world, then the appearance of mercury thunderate made it easier for this fire to appear.

"Hydrochloric acid, nitric acid, and sulfuric acid are all equally important, but it's a pity that I gave them all to Fili, and she's probably too busy. Rafa pondered for a long time, and on the paper he listed only the materials necessary to make the initiating charge.

In fact, he understands that if you want to develop a large-scale industry, you can't just make a little bit of everything, but you need a large number, even an amazing quantity, but with the current situation of Icefield City, although the resources are quite complete, there is really no manpower, and the people who can be freed up can't understand these bottles and cans, so this plan obviously has to be postponed again.

"When spring begins, you can try to recruit some alchemists. ”

After thinking about it for a while, Rafa had unconsciously written many, many words on the paper, and many words were explanations for a certain material, which would have to be handed over to Phililisil sooner or later, and he was afraid that she would not be able to understand them, so he wrote a lot of explanations;

"The church says that God has enlightened people's wisdom?

After a long time of drawing, in addition to the necessary materials, he drew drawings of a wheeled 75-mm field gun, a mine, and an ovoid grenade.

None of these things are precise, as long as Lilith can understand what he means, she can "cut" out any shape for you, and he once drew a simple artillery drawing, but Felihill seemed to understand the actual role of the cannon, so she didn't let Lilith make it.

Mines and grenades are the easiest to make, and even the simple mechanical milling machines in the ironworks can make all the parts, although the handmade parts are probably not reliable, but for mines and grenades that only need to be stupid and thick, as long as they can be assembled, it is enough.

Looking excitedly at this drawing with cross-era significance, Rafa was in a good mood.

"Your Highness, I'm sorry ......"

In the midst of his excitement, Audele's apologetic voice startled him.

"Huh?" Rafa turned her head in confusion, and found that Audrey had fallen asleep on the bed at some point, and was now curled up in a ball, still holding her long sword in her hand.

"It turned out to be a dream talk. ”

Rafa smiled, stood up, walked gently to the bed, took off his coat, and covered Audrey.

Then he picked up the drawing that had taken him in the middle of the night and cautiously walked out of the room.

"Good morning, Fili. ”

As soon as he left the room, the well-dressed Felicille was leaving him with a back, and she didn't look back when she heard his greeting.

"Fili, come and see this!" Seeing that she ignored herself, Rafa didn't care, and quickly ran to Felihill's side and took out her own drawings.

"Today is a day off. ”

Felihill surprised not to take it, didn't even look at him, replied indifferently, and walked forward without stopping.

Rejected by Felicille, Rafa stayed where she was, somewhat bewildered, and watched as Felicille disappeared into the hallway.

He stood there for a while, until the cold wind blew the ends of his hair, and then he said, "I'm sorry." ”
