"Is this the legendary cannon?" Mo Bai stared at the painting on the paper for a long time, looking at McGonagall with a slightly strange expression, no matter how he thought about it, he felt that this thing didn't look serious, and he couldn't imagine how to use this thing to throw it out.

McGonagall also stared at the paper for a while, she hadn't picked up a drawing for many years, and had degenerated into a soul painter...... It's hard to say.

"This is a sketch, I'll draw you a detailed schematic." McGonagall calmly flipped the page, sat upright, and drew carefully on the paper with the pencil in her hand.

McGonagall painted Mo Bai with the simplest artillery, almost the level of the red-coated cannon in the late Qing Dynasty, the cannon barrel, the front-loading loading method, the principle is simple, and the manufacturing is relatively easy.

Of course, the most important thing is that McGonagall, a more advanced gunner, doesn't know much either, and it is really difficult for him to draw schematics.

If it wasn't a problem for him to draw a schematic diagram of a firearm, he was familiar with it.

However, the difficulty of manufacturing firearms is not comparable to ordinary artillery, and the requirements for various processes are extremely high, and it is much more difficult to make a lethal firearm than to make a simple artillery.

After all, he was born in a professional class, and a man who could draw drawings of internal combustion engines with his bare hands back then, when he got serious, it was naturally not a problem to draw a schematic diagram of a simple artillery.

"The principle of artillery is actually very simple, but the lethality mainly depends on the explosives enclosed in a closed iron ball, and the energy released at the moment of explosion determines whether the bomb can kill a dragon, if the specific principle is ......" McGonagall drew while explaining the principle of the artillery throwing the shell out in simple terms.

Mo Bai also gradually became convinced from being skeptical at the beginning, his eyes became brighter and brighter, and his expression became more and more adoring, as if he had been opened the door to a new world.

"The specific principle is probably like this, the core and most critical thing in making artillery is the strength of the gun body, which determines the effective range of this artillery, you are a blacksmith, you should know more about this than me." McGonagall put down the pen in her hand, and three standard fire** sheets of paper had appeared on the paper, and even the manufacturing process was marked in detail.

"Boss Mai, you must be a genius." Mo Bai stared at the drawings for a moment, then looked up at McGonagall, her eyes full of admiration.

McGonagall's cooking skills had conquered his stomach, and he was completely impressed by the genius he had now revealed.

If the explosives he had inadvertently experimented with were a novel discovery, McGonagall's idea was to make a feasible use of this novelty.

What a genius idea to use the huge energy generated when the gunpowder burns violently to push the projectile-shaped explosive to fly out, and to create a confined space with a semi-enclosed long tubular barrel and at the same time to make the shell have a controllable direction!

"I'm not a genius, I just know a little bit more." McGonagall smiled and shook her head, it seemed that Mo Bai should understand what he meant, as for what level of artillery he could make, it was not for McGonagall to worry about, how to make a cannon barrel that met the standards estimated to waste a lot of time.

And until the problem of gunpowder stability is solved, everything cannot be carried out.

As a man who can make her own bullets, McGonagall actually has a lot of research on the ratio of gunpowder, but Mo Bai's method of adding Warcraft crystal nucleus powder to gunpowder to increase the power of explosives is simply black technology.

This made McGonagall stop the urge to make suggestions, and without the constraints of fixed thinking, he might really be able to make a terrifying explosive.

After all, this is a different world, and it is difficult for bullets made of ordinary gunpowder to even break through ordinary demonic beasts, which is why McGonagall feels that even if thermal weapons appear in this world, it will be difficult to change the world pattern, after all, a powerful fire mage is better than a cannon.

But the magic crystal gunpowder that Mo Bai had made before made McGonagall see a certain possibility, whether it was a powerful bomb, or using them in a firearm, after the huge energy concentration exploded, maybe it could really pose a threat to the dragon.

"Cast as a whole, and it needs to be able to withstand the previous level of explosion, it is really not an easy thing to make such a cannon body, but I will study it carefully." Mo Bai put away the two pieces of paper on the table, got up and looked at McGonagall and said solemnly.

"You're welcome, but I still hope that the explosion test will not be done at home in the future, otherwise it will be a little insecure to live next to it." McGonagall smiled and shook her head, not forgetting to remind her again.

According to the principle of gradual death, the degree of death will gradually increase with each death, and McGonagall does not want to be blown up in her sleep one day.

"Not anymore, not anymore." Mo Bai hurriedly waved his hand.

"Boss Mobai? Are you still alive? At that moment, a hearty call came from outside.

"The person who repaired the house is here, Boss Mai, I'll go first, I'm really sorry for today's incident." Mo Bai glanced towards the door and said a little apologetically.

"Okay." McGonagall nodded, and didn't say anything more, anyway, he was also a neighbor, and Mo Bai was still the first customer in the restaurant.

"The magic cannon might be fun." McGonagall looked at Mo Bai's back as he went out, the corners of her mouth slightly raised, and she suddenly looked forward to the scene where Mo Bai pulled a cannon and blasted the dragon in the sky down with one shot.

Putting away the notebook and cups on the table, McGonagall turned and headed towards the kitchen, fastened her apron, and began to prepare the ingredients for breakfast.

When she held the kitchen knife, McGonagall felt a little numb in her entire right hand from between her fingers to her shoulder, and the high-intensity exercise last night still had a little effect on her body, but the benefits were obvious, and her body's agility and reflexes improved.

After slashing twice, McGonagall suddenly stopped, looked at the kitchen knife in her hand, and then looked at the chicken leg on the cutting board, and thought to herself: "Now the most repeated thing every day is to chop vegetables and cook, and each action is repeated thousands of times. ”

"Chop." McGonagall took a half-step back, and with a soft mutter, the kitchen knife in her hand slashed down, and the chicken leg broke off at the knife, and the cut was flat, leaving only a shallow knife mark on the cutting board.

"It's okay, but the control of the force needs to be strengthened a little." McGonagall nodded slightly, and the kitchen knife in her hand slashed out again, faster and faster, and the chicken turned into small diamond-shaped squares under the knife.

The angle and strength of the knife are a little different from before, but as time passes, the deliberate beginning slowly becomes more proficient, and the speed is getting faster and faster, and you can almost only see a golden light flashing, and the whole chicken leg becomes an even small piece.
