Hearing Mei Feng's words, Alberg smiled slightly, as if he was not surprised by his performance, but his refusal was very clean: "No."

"As I told you before, this Franc cannon is not only the pride of our royal firearms research and development, but also an important secret firearm that we now possess, and its sophistication is among the best in the world."

"It's already an exception to put it out for you to see today, so how can I sell it to you again? It's a no-go."

When Mei Feng heard this, the hope in his eyes was instantly extinguished, but Gu Yunji still didn't give up: "It's really impossible? Of course, we know the importance of such a delicate firearm, and how can Mr. Eberg know that the conditions we have set will not tempt you?"

Alberg was adamant: "It's really impossible. The Fran cannon is in a special position in my royal family, and we will not agree to sell it on any of the best terms you offer."

Hearing him say this, Gu Yunji had no choice but to give up, but in his heart he was still unwilling to let the imperial court lag behind others in firearms technology, and he was eager to grow ten pairs of eyes at the moment, see the internal and external structure of the Franc cannon clearly, and go back so that the craftsmen of the government could imitate it.

Alberg was not worried about this at all, and the people accompanying him this time were basically officials of the imperial court or official servants, and they were all laymen along with firearms. Firearms manufacturing requires a great deal of expertise, and even if a layman can see the difference, he will not understand the subtle difference.

Anyone with eyes knows that the advanced point of the Franc cannon lies in the design of the "child and mother gun", but it is one thing to know that imitation is another.

Even if the level of firearms manufacturing technology in Huaxia is very high, based on the eyes and words of Gu Yunji and a few people, if the craftsmen of the government want to imitate, they will not be able to achieve anything without three or five years.

Therefore, at this moment, Gu Yunji and the others observed this Franc cannon carefully, but in Eberg's opinion, it was all useless. In order to show the magnanimity of the royal family, he even called in a few retinues to push the Franc cannon onto the deck for a simple firing demonstration, so that they could understand it more clearly.

「…… In addition to continuous firing, the Franc cannon also has the advantage of a long range. A cannon like this usually has an effective range of more than one mile, and the maximum range is nearly three miles!"

In the face of Alberg's gushing introduction, Gu Yunji was secretly frightened when he heard it.

The effective range of more than one mile is quite remarkable for naval warfare at a time when broadside warfare was still popular. In the broadside battle, the throwing distance of dart guns and lime bullets is generally tens of meters, and the maximum is not more than 100 meters.

Gu Yunji didn't know how credible Eberg's words were, whether he was deliberately exaggerating the facts to deter them, but since the other party could say this, he must have a certain amount of confidence.

It is said that Huaxia is the kingdom of the Celestial Empire, which is not only the opinion of the Chinese people themselves, but also the general understanding of the rest of the countries. In recent years, Westerners have made great geographical discoveries, developed navigation technology by leaps and bounds, and traveled all over the world, which began to slowly breed the idea of challenging the authority of the Chinese Celestial Empire.

Obviously it is a crucial advanced firearm, but he is still willing to show it to Gu Yunji and others, Eberg's move is not only to win the trust of his partners, but also to show off his military strength - what about the Celestial Empire, such advanced firearms, you don't have them?

Gu Yunji is still okay, mainly Mei Feng and a few people, who have been confident in the face of foreign envoys for many years, and have never felt suppressed in all directions, and they felt a little aggrieved and uncomfortable for a while.

Shen Baiyi is good at theoretical research, and he is also involved in firearms, and he is not a layman who knows nothing. Hearing this, he couldn't help but doubt Alberg's words:

"More than a mile of effective range? I'm afraid I'm talking big. Not to mention whether your Franc cannon can hit that far, the key is how do you aim? At a distance of several miles, no matter how big the ship looks like a small black dot, who dares to say that they will be able to hit it?"

Seeing Shen Baiyi's questioning, Alberg seemed to be a little dissatisfied: "With the naked eye of a human being, a distance of several miles will naturally not be missed, but our Franc cannon is different, and there is a special aiming device on it."

Shen Baiyi's eyes widened when he heard this: "A special aiming device?"

In this era, firearms were basically aimed at by the naked eye, and the more important and large the artillery, the more experienced veterans were needed to operate it. The naval divisions of the imperial court not only lagged behind in the lack of advanced naval combat firearms, but also lacked soldiers who could operate firearms.

And before that, Shen Baiyi had never heard of any special aiming device.

"Yes, a device for aiming, which is of course the only invention of our royal family!" Seeing Shen Baiyi's reaction like this, Albert's expression was faintly complacent, and he casually pointed to an attendant and said, "You, go and show Lord Shen how our aiming device is used."

This attendant is an East Asian face, maybe even of Chinese blood, with dark skin, and he has experienced many years of wind and rain at sea, and his face looks very honest.

Hearing Alberg's words, he seemed to be a little restrained, glanced at Gu Yunji and his party a few times with a slight stagger, and then demonstrated it in the stumbling official dialect of Daxia while introducing Shen Baiyi.

"Your Excellency, please see, the sighting device is here, this is called the front sight, this is called the door, it should be used like this......

After the acolyte's demonstration, Shen Baiyi briefly got started, and when he saw a reef in the distance through the scope, his eyes instantly widened, and he couldn't help but exclaim: "This, this...... It's amazing!"

"That reef is more than a mile away from us, and we can't see anything but the vast sea, but through this aiming mirror, it is so delicate that even a seabird above it can be seen clearly!"

Telescopes are still quite scarce in this era, and Rao is Mei Feng and others have never seen such a good aiming device with telescopic ability. Hearing Shen Baiyi say this, he couldn't help but arouse his curiosity, and they all wanted to try it.

As for Gu Yunji, he had never heard of any telescopes in his previous life, and compared to this so-called "exquisite" aiming device, he was now more concerned about another matter.

Zhao Jinbao, as a gunsmith in the Franc machine caravan, his main business on weekdays is to tinker with firearms, but the status of the Chinese in the caravan is very low, and most of the time they stay in the rear and do not see outsiders.

If it weren't for the people from the government to visit today, and someone who knew the official dialect of Great Xia needed to serve by his side, he probably wouldn't have had the opportunity to go on deck.

Seeing that Shen Baiyi and the others had gradually mastered the essentials of using the aiming device, Zhao Jinbao knew that his task was completed, so he retreated quite knowingly and waited silently to the side.

At this time, he saw the Shaoxing prefect in a scarlet official uniform walking towards him, with a kind smile on his face: "I just heard Brother Tai speak official language, with a somewhat familiar accent, calling me very kind, I don't know if it's a person from Shaoxing Mansion?"
