"You look better than Grava Chaina!"

After Ariana finished speaking, she quietly looked at Charles, observing his further reaction, although she had recognized this when she was in Greencastle, but now she was still somehow a little apprehensive.

Will he admit it? Should he admit it?

Ariana was actually conflicted.

"You think I'm better looking than Grava Chaina, I'm a god, hehe!" Charr chuckled, kicking Ariana's ball crookedly without a trace.

"On the surface, it's better, but it's ....... in essence It's the same. Charles didn't answer her words, and Ariana was a little disappointed, but she wanted to keep trying.

"Ariana, how did you remember to associate me with Lord Grava, I've seen his portrait, and he doesn't look like me at all!"

Ariana's expression became warm as water, and her eyes fluttered as she recalled: "When I first met Lord Grava, I had a very bad attitude towards him, but when I was about to be killed by the priests of the Moorish Church, it was he who saved me........."

"Lord Grava has revealed the true body of the Divine Servant, and I will never forget the dazzling and pure light, which made me feel the power of God........."

"Later, I found an opportunity to be promoted to the middle rank through painting, and at the moment of promotion, I seemed to feel that His Excellency Grava was beside me, but I looked carefully but could not see him........."

"Since then, His Excellency Grava has disappeared, and I have quietly searched all over the Radel district, but there is no news of him, I think......... I'll never see him again........."

"But ........."

Ariana's misty eyes were in focus again, focusing on Charles's face, "Just the other night at Fort Greensen, I felt the breath of Lord Grava again, and the breath imprint in my body will not deceive me............"

"That's when I remembered that when I was promoted, and when I was in Castle Green, there was the same person who was with me, and I kept missing ........."

"Ariana, do you think there really is such a coincidence? I can tell you for sure that the stories of coincidences are all lies. ”

Charles still has no change in his face, there are some things that he can't admit even to death, the things in the Dawn Sanctuary were indeed stolen by me, but even if you all believe that it is me, I am just hard-mouthed, what can you do with me?

But Charles looked at Ariana's unmoved eyes, obviously identifying him.

"Ariana, there are some things that are difficult to explain, maybe you and I have some special talent for compatibility, so we only cooperate very well when we are in Castle Greensen, so I can't be Grava Chaina. ”

"Can't you?"

Ariana's eyes darkened slightly, and then suddenly they lit up again? Isn't it impossible?

"Well, whatever you want! By the way, how are you doing in your search for Grava Chaina?

Ariana suddenly smiled, very happy, very beautiful, like the beauty of the moment when the snowdrops on the iceberg bloomed.

"If Lord Grava is unwilling to let us find him, I don't think we will find him, and it will be in vain to continue looking!"

Ariana stood up, bowed deeply to Charles, and said, "I should take my leave of the Marquis, and I will explain all the questions of the Church, and you will not be disturbed in any way." ”

“..........”

Charles looked at Ariana as she drifted away, and didn't know whether to say that she was smart or stubborn!

..........

..........

After Ariana leaves, Charles goes with him to the collaborative research lab he has built with Prus.

On the western outskirts of Nancy City, on an unobstructed plain, the cooperative research laboratory has chosen the most central area to fence off the fence, and the large open space around it forms a "safe zone"? All those who try to sneak close to the research room will be exposed to the wilderness, unless they are transcendents like assassins or middle-rank hunters?

After Charles entered the wilderness, the cavalry squad in charge of the perimeter guard raised the signal flag corresponding to today's date, and the sentry Marquis Marquis at the asana lookout post arrived.

"Boom!"

"Boom!"

Before Charles could reach the door of the research room, he heard a continuous explosion from inside the research room.

"Two dead women? I dare to test it casually before I arrived? Be careful to blow up you two goblins.......

Charles cursed hatefully with hatred on his lips, and the horsewhip in his hand slapped the big black horse's buttocks, and the aggrieved big black horse didn't dare to squeak, and ran wildly with his hooves out, eager to turn this seemingly thin but heavy guy on his back.

Charles rushed into the door of the research room, and rushed directly to the edge of the test field, just in time to see Olive and Linar in high spirits.

And that latest horse-drawn artillery is the Shire's greatest military achievement in recent days.

Artillery has existed on the mainland for a long time, but its rapid development is still a matter of recent decades, especially the Hundred Years War between Ference and Engelo and the large and small battles in the process of the unification of Prussia, which gave birth to a very high level of artillery on the mainland.

More than 20 years ago, His Majesty King Roself of Florence pioneered the tactic of "centralized use of artillery" and unified the basic standard of artillery formation of "artillery company", and a series of reforms played a huge role in the defeat of the Engru at the end of the Hundred Years' War.

From then on, each of the main armies of Florence would be equipped with several artillery batteries, and each artillery company would have three to five guns, and the density of fire from dozens of guns was among the highest on the mainland.

However, after learning about the ration of artillery in the Flensian army, Charles still pointed out the shortcomings and shortcomings of one kind or another, and in his opinion these artillery were still far from the artillery level of Napoleon's time, and there was a lot of room for improvement.

However, when Charles was really preparing to change the artillery, he knew how far the distance was between the "dreamers" and the "doers", and also understood why so many inventors in history were apprentices with no higher education but strong hands-on ability.

Charles knew that the best material for artillery in this era was bronze, and even knew that the optimal ratio of copper to tin was about ten to one, but when he actually started casting cannons, it was not like that, and he tried countless times, and wasted many precious metals copper to barely get a satisfactory result.

Since then, Charles has decided to cooperate with Cousin Linar for a limited degree of in-depth cooperation, after all, a big thing like an artillery can't be hidden in terms of structure, you can make a finished product on the front foot, and the cousin on the back foot can see the details clearly at a glance!

What? You don't want to show her? Hehe! The defense industrial base of the Lorraine region is still counting on the Prussian people's vigorous and selfless assistance! Who is more stupid than whom?

With the rich experience of seeing many "mouth-moving elites" in the unit in his previous life, Charles quickly turned around a dozen excellent craftsmen, and he also earned the image of a "master".

"Olive come back to me, I warned you not to shoot the cannon casually, what if it blows up and collapses?" said Charles, jumping off his horse and shouting angrily at the two women.

Olive glanced at Charles, and left the aiming position unhappily, moving to Charles' side with an unhappy expression.

And Cousin Linar had already smoothed out her hair and dress, and walked over with a graceful demeanor, as if she was not the one who was dragging the arquebus to shoot the cannon just now.

This is the difference between having no distractions and having intentions.

..........

..........

"Boom!"

"Measure the distance, calculate the time, calculate the velocity of the cannon!"

With the sound of a cannon, both Linar and Olive with their precise stopwatches bowed their heads to record something on the paper, but Olive then began a quick calculation, on which Linar drew an unfinished sketch.

She does not understand the so-called "formula of acceleration motion", let alone the fact that the distance between the rising and falling processes of the parabola of the projectile motion is nearly equal, so naturally she cannot calculate what the muzzle velocity of the shell is.

But Linar has learned to be at peace, and she is willing to use this time to paint a picture of a man's most handsome moments.

"The firing angle of elevation is five degrees, the distance is 1480 meters, the flight time of the shell is about 4.5 seconds, the muzzle velocity of the shell is ...... 476 m/s. ”

Olive recorded a value in her notebook, comparing it with the previous ones, and wondering where the error was.

"Raise the elevation angle to ten degrees and measure ten times in a row!"

Charles reissued the test order, then slowly paced behind Linar to see what she was drawing.

Linar didn't shy away from Charles, and even asked lightly: "Did I paint a portrait?"

"Oh...... You look like you're drawing me?"

Linar smiled at first, and then said solemnly, "I'm drawing a stupid pig!"

“.........”

"Boom!"

"The firing angle was ten degrees, the distance was 1900 meters, the time was about 6.5 seconds, and the muzzle velocity was 465 meters / second. ”

"Shoot at an elevation angle of ten degrees, at a distance of 1860 meters........"

"Charles, the artillery is overheated, 19 rounds in a row!"

Olive finished her work and looked back to see Charles glaring at Linal, who was writing and drawing on the paper with her head down, a smug smile on her lips.

"Charles, the artillery is too hot, it's going to explode!"

"Got it, go test the grenade, but I warn you, you are not allowed to test it yourself until it is ripe. ”

Olive pouted again, but this time she didn't dare to scold Charles again, as she was well aware of the dangers of this new throwing weapon.

The grenade is not the first weapon of the Charles, but because the disadvantages of the dud rate and the open flame fuse have not been solved, it has not been popularized in the field troops, so they will only appear in the castle attack and defense battles, and the Charles this time is to say the principle of the improved fuse of the fuse, so that the technical craftsmen of Pruss and Lorraine can concentrate on tackling the problem.

Because of the appearance of thundermercury gunpowder, the conditions for the realization of the pull fuse have been met, and the experienced technical craftsmen quickly improved several new grenades, but the accidental explosion rate in the early experiments was a little high, which made Charles very depressed.

If there is even one case of accidental bombing in the army, the soldiers will resist the use of it, which will seriously affect the improvement and development of infantry tactics.

In desperation, Charles had no choice but to turn to Linar and ask her to find an alchemist to try out a suitable time-delay powder, and it was not until yesterday that there was an update.

"Your Excellency, are you ready, do you want to start?"

The craftsman prepared the grenade and asked the charr for instructions, and after receiving the charr's nod, the warrior in heavy armor walked up.

"The first shot, the estimated delay is ten seconds!"

"Whoosh!"

A grenade was thrown, and it fell far away seventy meters, and it was clear that this fighter was not an ordinary fighter.

Twelve seconds later, the grenade exploded, and the technicians watching from the sidelines were very excited.

"The second method, the estimated delay is six seconds!"

"Boom!"

"Boom!"

After a series of throwing tests, both Charles and Linar were very satisfied, but in the end, they all wanted to set the fuse delay time at about four seconds, which was a bit different from Charles's suggestion of six seconds.

"We can't keep the time-delay fuse to four seconds, and if one or two seconds happens, it will blow up our own people!" said Charles, worried about the level of craftsmanship in the world.

But Olive disagreed, "Charles, if the delay is too long, the enemy will throw it back, so four seconds is already a safe time." ”

"But how many people would be so brave? I think they're more likely to choose to dodge!"

"No, you're wrong Charles, I don't know what the Flens soldiers are like, but the elite Prussian soldiers are brave enough. ”

Seeing that both women showed their "brave" nature, Charles couldn't say anything more, and if he said it, he would be cowardly.

Although there are too many scenes of picking up grenades and throwing them back in the anti-Japanese drama, Charles knows that this situation is only a very small minority, and after understanding the power of grenades, most people will be afraid of death to hide, and only those fools will play with fire to death.

In Shire's previous life, there was a large-scale war at the peak of the infantry of the East and the West, a large number of soldiers of the Great Celestial Empire attacked the positions of the Citi Nation at night, and at the beginning, there were brave Citi soldiers who sapped grenades flying in the air with sapper shovels, but after a few times they knew what the price of bravery was.

It's basically a death.

Since then, as long as the soldiers of the Great Celestial Empire rush to the throwing distance of the grenades, basically the GIs of the Citigroup will retreat and dodge, because the hail grenades will make the GIs who are born to play baseball despair.

Do you think anyone can hit a home run? One mistake is the cost of life, and how many times can those so-called Warriors get lucky?

Despite the slight differences, the experiment was largely satisfactory, and Charles and Linar agreed on a suitable technology transfer fee before returning to Sunset Castle together to discuss new infantry tactics.

However, as soon as they returned to Sunset Castle, Roy, the butler, came to inform Charles that the envoy of the Duchy of Lucerne had entered the border of Lorraine this morning and was hurrying towards Nancy.
