During this time, Luo Ji's continuous invasion wars obviously did not affect the development of the civilization of the Ten Thousand Worlds.

As the side that was invaded, John Sal did not seem to have any intention of fighting against the invasion.

Luo Ji knew that the other party was jealous of him.

To be more precise, it was jealousy of his true purpose.

If he mobilizes troops without authorization and fights a war against the invasion, he may take advantage of it.

In order to avoid this situation, in the face of Luo Ji's continuous invasions, John Sal completely seriously fought a battle to defend the city.

By the way, it is worth mentioning that until now, there have been six invasion battles between Luo Ji and John Saar.

Probably because of his luck lately, several of them have invaded the border of the repeat.

This made him fight six times before he finally figured out all the borders on the other side.

As for the victory and defeat of these six invasions, Luo Ji won two games and lost four, obviously losing more and winning less.

But for this win-loss ratio, Luo Ji himself is not much depressed, and John Saar is not happy at all.

Because for Luo Ji, although he lost the invasion battle, he did not suffer much substantial loss, and he also achieved his goal.

As for John Sal, although he won, he didn't make much benefit at all, and in comparison, his own information was about to be figured out by the Celestial Empire player on the other side!

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

At this moment, Zhou Cang, who walked quickly into the hall, brought this news that made Luo Ji's expression obviously lifted.

"The cannon has been improved?"

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

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

As for the progress of the improvement of the cannon, Luo Ji is undoubtedly quite concerned.

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

During this period, Ye Xuan, 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 cannon as a weapon!

There was no need for Luo Ji to say anything, Ye Xuan, 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 the cannons of their Ten Thousand Worlds civilization in terms of range, power and accuracy, it seemed that they were competing with the other party, and Ye Xuan suddenly became even harder.

During this period, Zhang Ze (the chief ordnance engineer of the goblin), who was another deputy director of the Ordnance Research Department, naturally also assisted from the side.

In the past two or three years, the cannon of the Ten Thousand Worlds Civilization has been officially improved at least no less than ten times, and as for the number of small changes and experiments in private, it is estimated that there are too many to count.

However, this area is unfamiliar to them after all.

Even Luo Ji, who is a modern person, doesn't know much about cannons, so it is difficult for him to put forward any constructive opinions on the improvement of cannons.

Little by little, it all had to rely on Ye Xuan and Zhang Ze to slowly explore little by little.

In other words, it's time to fight for talent.

And Ye Xuan and Zhang Ze did not disappoint Luo Ji, from the initial effective range of only a little more than 100 meters, to the later effective range of more than 200 meters, and at the same time, the stability, accuracy and power of the shells have become higher and higher, and Luo Ji can see the progress in this.

As for this time, the improvement of the cannon seems to have made a big breakthrough, otherwise, just a small improvement would not alarm Luo Ji's side.

For a while, Luo Ji also had a little more expectation in his heart.

Outside of Spiegel, there is an area dedicated to the Ordnance Research Department, allowing them to experiment with some threatening weapons.

Luo Ji took a group of guards and rode a fast horse to arrive here.

Led by Ye Xuan, Zhang Ze, and Zhao Lei, the members of the Ordnance Research Department, who had been waiting here for a long time, hurriedly got up and saluted when they saw Luo Ji coming......

"We greet Your Majesty!"

"It's all excused."

Luo Ji waved his hand and motioned for everyone to get rid of all the red tape.

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

In this regard, Ye Xuan is naturally unambiguous.

After answering, he hurriedly took Luo Ji and ran towards his latest achievements with an excited face.

Zhang Ze and Zhao Lei, who were watching behind, broke out in a cold sweat.

In the vast test site, a cannon was already placed there.

Looking at the appearance, to be honest, Luo Ji really didn't see anything special, but he knew that this was not the point.

Raising the telescope in his hand and looking into the distance, he saw that several thick metal plates had been piled up in turn according to the distance in the test site!

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 point where it is just 'suitable'.

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.

Without ambiguity, the professional artillerymen were decisively signaled to operate.

Skillful movements, so that they are quickly ready to be in place.

Then he turned his head to Luo Ji and asked whether to open fire.

In this regard, Luo Ji nodded slightly, 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.

The cannonballs, which flew out with smoke and fire, first hit the metal plate at a distance of 100 meters.

Under the joint improvement of Ye Xuan and Zhang Ze, within a hundred 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, Luo Ji estimated that the destructive power of this cannon within a hundred meters was probably more than that of a three-bow bed crossbow!

The update is sent, and at the same time, I would like to thank the book friends for the monthly passes of 'Willow Tree Wants to Sprout', 'Saiwai Xiaoxiong', 'AXG', and 'Text Liu'!
