The gradual improvement of intelligence made Xia Qi's invasion war unhurried.

In the notebook of the military clerk, several pages of terrain information, troop allocation, and countermeasures about the dwarven civilization have been written.

All of these were recorded through Xia Qi's dictation.

It is worth mentioning that in the imperial palace of Great Xia, there are already some existences similar to historians.

Their daily task is to record Xia Qi's words and deeds, what they do and what they say every day, these will be recorded.

This is because, as time goes on, many things before will gradually become blurred in Xia Qi's memory.

Therefore, it is better to record some important things through paper documents.

Straight to the point.

This is just the beginning, because this side of the information alone is not enough.

When you meet a powerful opponent and want to make a formal move, you have to touch all the borders on all sides.

In this way, the invasion has been fought for the seventh day.

In seven days, he carried out three rounds of attacks, and neither of the offensive and defensive sides could take anything from the other, and the problem of casualties of the troops was completely under control.

Xia Qi estimated the system score in his mind, and it can only be said that it is more subtle, and it is really not accurate who wins and who loses.

However, Xia Qi, who had collected information, did not plan to continue fighting.

After a short period of thought, in the end, he chose to retreat.

【You have won this invasion】

You have earned 12,451 Civilization Points.

"Hoo ......"

Looking at the system prompt, Xia Qi exhaled.

It seems that this invasion war was won by itself.

However, judging from the civilization points obtained, the system score obtained by himself is actually not much more than that of the previous one.

Perhaps, it is a single-digit advantage.

The Romanov on the other side did not seem very happy after hearing the system prompt.

Although he was only deducted more than 10,000 civilization points, in his opinion, this was completely unwarranted.

"Forget it, the last invasion battle, this defensive battle, was won by that Huaxia player. I hope he can be self-aware and stop bothering me. ”

But it is clear that this is nothing more than wishful thinking on the part of the Romanovs.

At this time, he didn't know that he had been targeted by Xia Qi.

What Xia Qi wants is not just civilization points, and other special points, but an entire dwarven civilization!

[The Chinese player "Xia Qi" has launched an invasion against you]

A month later, Xia Qi launched another invasion of the Romanovs.

After hearing the system prompt, Romanov, who was smoking, didn't come up in one breath and almost choked to death.

"Shit!"

What does this mean?

It's completely up to him, isn't it?

Romanov's face instantly became cloudy.

Doesn't it mean that Chinese people value harmony?

Why did this guy fall into trouble with himself?

Just because of an invasion of your own?

At this moment, the Romanov scolded Xia Qiyi in his heart.

At the same time, it is also a grudge against Dunk Joseph.

However, Xia Qi didn't care what he thought, and continued to command the army under his command, while attacking the border cities of the dwarf civilization, while collecting intelligence.

Then, when the seven days came, they retreated decisively.

But this time, the loser was replaced by Xia Qi.

At the same time, he was also deducted Civilization Points in his early 20,000s.

During this time, Xia Qi's continuous invasion wars did not affect the development of Great Xia, and as the invaded side, the Romanovs did not seem to have any intention of fighting against the invasion.

Xia Qi knew that the other party was jealous of him, and to be more precise, he was jealous of his true purpose.

Romanov understood that if he mobilized troops without authorization and fought a counter-invasion war, he might be taken advantage of by Xia Qi.

In order to avoid this situation, in the face of Xia Qi's continuous invasions, the Romanovs began to hold on and began to defend the city. In the period that followed, Xia Qi launched a total of five invasions against the Romanovs.

The reason for the five is because one of them was teleported to the border of the duplicate side.

In these five invasion battles, Xia Qi won three and lost two, which can be regarded as winning less and winning more.

It took so much effort, but in the end the result was good, and he had completely figured out the borders of the Romanovs on all sides.

Looking at the notebook in his hand, which was already full of intelligence information, Xia Qi at this time was sorting out the thoughts in his head, and at the same time, he was arranging the next things.

At that moment, one of the guards who walked quickly into the temple brought him good news.

"The cannon has been improved?"

"Yes, Your Majesty. According to the news from the Ordnance Research Department, the new cannon is now being test-fired outside the city. ”

"Let's go, let's see!"

Regarding the progress of the improvement of the cannon, Xia Qi can be said to be quite concerned.

After all, he is familiar with the history of modern warfare, but he knows the position of future artillery in the battlefield.

It's been about three to four years since the cannon was built.

During this period, Xia Fox, as a master of ordnance, naturally knew the weakness of the cannon, but at the same time, she also saw the potential for development from the weapon of the cannon!

There was no need for Xia Qi to say anything at all, Xia Fox, who had keenly captured this, had already devoted himself to the follow-up improvement of the cannon.

Especially later, after learning that the cannons of the dwarf civilization were better than their cannons in Daxia in terms of range, power and accuracy, it seemed that they were competing with the other party, and Xia Fox suddenly became even harder.

During this period, Wang Jie, another deputy minister of the Ordnance Research Department, also assisted.

In the past two or three years, the cannon of Great Xia has been officially improved at least no less than ten times, and as for some small changes and experiments, it is really too many to count.

However, this field is unfamiliar to them after all, even Xia Qi, who is a modern person, does not know much about cannons.

Therefore, it is difficult for him to put forward any constructive suggestions on the improvement of the cannon.

Therefore, the improvement of the cannon was all based on Xia Fox and Wang Jie, who slowly explored it little by little.

Xia Fox and Wang Jie did not disappoint Xia Qi, from the initial effective range of only more than 100 meters, to the later effective range of more than 200 meters.

At the same time, the stability, accuracy and power of the shells are becoming higher and higher, and Xia Qi can see the progress in this.

As for this time, there must have been a big breakthrough in the improvement of the cannon, otherwise they would not have come to inform Xia Qi.

For a while, Xia Qi also had a little more expectation in his heart.

Outside of Great Xia City, there was an area dedicated to the Ordnance Research Department for them to test weapons.

Xia Qi took a group of guards and arrived here quickly on horseback.

Led by Xia Fox and Wang Jie, the members of the Ordnance Research Department who had been waiting here for a long time hurriedly got up and saluted when they saw Xia Qi coming.

"We greet Your Majesty!"

"It's all excused."

Xia Qi waved his hand and signaled that everyone was not more polite.

He couldn't wait to see how powerful the improved cannon would be!

In this regard, Xia Fox did not hesitate at all, and directly took Xia Qi to run towards his latest achievements with an excited face.

In the vast test ground, a cannon was placed.

Judging from the appearance, there is nothing special about it.

However, the shape of the gun is not the point.

Xia Qi held the telescope and looked into the distance, only to see that in the test site, several thick metal plates had been piled up in turn according to a certain distance.

These metal plates look simple, but they are actually exquisite.

In actual combat, units that are too small do not need to be bombarded with cannons, but units that are too large cannot reflect the accuracy of cannons.

Therefore, in order to conduct a relatively accurate test of the range, power and accuracy of the cannon in this test, the size and hardness of the metal plate must reach a just right point.

This troublesome requirement also made the blacksmiths of the craftsman department spend a lot of work.

At the same time, the metal plates that were used as cannon targets were also marked with words such as 100 meters, 200 meters, 250 meters, and 300 meters.

Then, Xia Qi began to signal the professional artillerymen on the side to operate.

After all the preparations were completed, they turned to look at Xia Qi and asked him whether to open fire.

Seeing this, Xia Qi nodded, and then opened his mouth slightly while covering his ears.

Seeing this, the guards behind him also did the same.

Soon, a deafening roar resounded throughout the wilderness, and the cannonballs, carrying the smoke and firelight, first hit the metal plate at a distance of 100 meters.

Under the joint improvement of Xia Fox and Wang Jie, within 100 meters, the hit rate of the cannon is already quite high.

In the face of this powerful shelling, accompanied by another loud sound that almost caused cardiac arrest, the metal plate at a distance of 100 meters was blown away on the spot.

Although he hadn't stepped forward to make further careful confirmation, through the visual inspection at that moment, Xia Qi estimated that the destructive power of this cannon within a hundred meters was probably completely more than the Eight Bull Crossbow!

His Majesty the Emperor's presence in person made the members of the Ordnance Research Department feel extremely high.

In the test site outside Daxia City, the roaring sound of cannon fire continued to sound, blasting away the cannon targets set up in the distance one by one, showing the power and accuracy that Xia Qi was satisfied with.

Just now, the metal plate three hundred meters away had been blown away with considerable precision by a shell.

At that moment, all the members of the Ordnance Research Department who were present cheered uncontrollably.

This is a new breakthrough, which proves that the cannon of Great Xia, with ensuring power and hit, has officially extended its effective firing range to three hundred meters!

During the shelling test, the four metal plates that were blown away were quickly sent to Xia Qi in turn.

The surrounding members of the Ordnance Research Department, led by Xia Fox, also surrounded one after another, wanting to further confirm the power of the shelling.

These metal plates, when they looked at them from a distance, were not very large, and when they were delivered to the eyes, they found that they looked like small walls.

The metal plate that stood at a distance of 100 meters was undoubtedly the most damaged, and the entire metal plate had been pierced, and there were obvious cracks scattered around it.

The one at 200 meters penetrated a little.

The one at two hundred and fifty meters, although it was not pierced, but a whole metal plate was also twisted and deformed.

The last 300 meters were the most complete, but the surface had been clearly deformed by the shells.

Xia Qi exhaled a long breath, and then kicked the last piece of metal with his foot, feeling the hard and thick touch that came back.

He nodded in satisfaction.

For the power of the cannon this time, Xia Qi was satisfied.

The metal plate can be bombarded and deformed from 300 meters away, and the destructive power caused to the city wall is definitely considerable.

"How stable is this cannon and how much does it cost to produce?"

Faced with Xia Qi's question, Wang Jie hurriedly handed over a document in his hand respectfully.

After turning the two pages, although he was already prepared in his heart, Xia Qi's brows were still wrinkled uncontrollably.

This cost is really not cheap!

Although it can produce stably, the production cycle is also significantly longer than that of the eight-bull crossbow and catapult.

At the same time, gunpowder and cannonballs, which are consumables, are obviously more valuable than those of heavy crossbow arrows and catapults.

Comparing these three siege equipment as firepower output, the Eight Bull Crossbow undoubtedly has an advantage in range.

And the catapult is less advantageous, and the range is already half a catty.

At the same time, the attack trajectory of the catapult is with an obvious large arc parabola, which is inferior to the cannon in terms of accuracy, not to mention the power.

After thinking about it again, Xia Qi called Xia Fox over.

"How much time will it take to increase the effective range of the cannon to more than 400 meters under the premise of ensuring power and accuracy?"

Faced with this question, Xia Fox's two thin willow-like eyebrows suddenly wrinkled.

"Hmm...... I can't really say for sure. ”

In this regard, Xia Qi was not disappointed.

After all, this kind of thing doesn't mean that he can strengthen it if he wants to.
