Luo Ji's voice undoubtedly attracted Ye Xuan's attention.

As soon as Jiang Zhan and the others saw Luo Ji coming, they all hurriedly bowed and saluted.

There was also obvious nervousness in his expression.

Obviously, Luo Ji's trip came too suddenly.

In comparison, Ye Xuan is not so restrained.

Although Luo Ji is now a high-ranking emperor, she still doesn't have much nervousness when facing Luo Ji.

Because the two have known each other for too many years, how can the old people who have followed him all the way to the present not know about Luo Ji's character?

Attention instantly shifted to what Luo Ji had just said.

"Your Majesty, did you just say that you returned to the cannon? What's going on with that return gun? ”

Luo Ji was not surprised by Ye Xuan's reaction at all.

After sorting out the thoughts in his head, I only listened to him speak slowly......

"The so-called return cannon can actually be understood as an evolutionary version of the catapult......"

As he spoke, Luo Ji said his understanding of the return gun.

Although the Huihui cannon carries the word 'cannon', it actually has nothing to do with firearms.

It's still a cold weapon through and through.

In addition to this name, it is also called Xiangyang cannon, boulder cannon, and stone thrower.

In fact, all similar weapons are summed up in the words 'catapult', and there is nothing wrong with it.

Because their attack is to put it bluntly, throwing boulders.

Of course, this return cannon obviously has more power and range than the earlier catapults.

took over the design drawings and transformation plans drawn by her from Ye Xuan's hands.

Luo Ji looked through it unhurriedly.

Large ordnance, the quasi-head is not easy to control.

The quasi-head with a parabola is worse.

It's hard to get rid of this problem.

He didn't have much hope.

So at first, when Luo Ji asked Ye Xuan to improve the catapult, he mainly asked her to strengthen the power and range of the catapult.

The catapult's attack is based on the principle of leverage.

The range and destructive power of the boulder come from the explosive power and inertia of the moment the lever bounces!

The explosive power of the lever comes from its swing amplitude.

In other words, the greater the leverage.

The more explosive and inertial it will be.

The more range and destructive the boulder will be!

With this idea.

Ye Xuan naturally knew where to start.

However, increasing the swing of the catapult's leverage is not as simple as it says.

She and Jiang Zhan experimented and improved at the same time.

An ordnance is a whole.

Changed the structure of one of the components.

Then the structure of other components has to be changed along with it.

Then they changed and changed, and the catapult was changed by them to get bigger and bigger.

By now, I can't see the original appearance anymore.

Those who don't know think they're doing something new.

Regarding Ye Xuan's transformation direction, Luo Ji undoubtedly gave affirmation.

To be honest, Luo Ji didn't expect them to change to this point at first.

His original idea was just to improve it casually, increase some range and power, and then make do with it.

Then wait until the next stage of development, and then there will be a big upgrade.

As a result, the two top ordnance engineers under his command were too capable.

By mistake, his original plan was disrupted.

This is really something that makes him cry and laugh.

Since it's all already like this, what else is there to say?

This trip really brought him a lot of surprises.

When I get back to my place.

Luo Ji directly brushed the auction house.

Originally, I wanted to get a silver-level design drawing down in seconds.

But there was no stock in the auction house.

This stuff is obviously very sought-after.

I couldn't help it, so I finally bought a design drawing of the black iron grade 'return cannon'.

Then I called someone to send it to the Ordnance Research Department.

Immediately after that night, he suffered from insomnia......

Luo Ji, who slept until the afternoon, was too full.

So he can't sleep at all now.

In the end, with nothing else to do, he simply opened the system page and studied his development panel.

With the rapid development of the civilization of the Ten Thousand Worlds, there are more and more various development projects in his development panel.

Even if he is an old driver, sometimes he has to study for a long time to determine an additional point.

I have to say, it's a great way to pass the time.

That's enough to kill a lot of his time.

After the round of additional points was completed, Luo Ji, who was leaning on the head of the bed, glanced at the sky outside through the window.

Apparently it's still early in the morning.

However, the brain is after it has undergone sufficient thinking activity.

Far from being sleepy, he is now more awake than before.

If this were in the real world, he would probably simply turn on the computer and play games.

Then the next day of sunset in the next round......

As for now.

Luo Ji left his bedroom.

Under the watchful eyes of the guards, I sat down at the desk of my apartment.

Although there is no piled up of working papers waiting for him to deal with them.

However, Luo Ji felt that he could sort out his future development plan.

Northland mountain forest development project.

Plans for territorial expansion in the steppe.

The later construction of Qingshui City in the city.

Sewer construction works in dozens of cities.

The further popularity of glass greenhouses.

And over there in the bitter cold.

Since he was going to explore steadily, he felt that he should temporarily clear a front-line camp on the outskirts of the bitter cold land.

What has been listed now is just a few important major projects within the civilization of the Ten Thousand Worlds.

If you count the small projects, the number is even higher.

At the same time, the question of the total number of troops in the territory.

Although the system of 'military service' has long been promoted.

Now there are already two groups of reserve soldiers.

But at the end of the day, there is no comparison between a reserve soldier who has only been trained for a period of time and a regular army that trains every day.

To put it bluntly, the reserve soldiers are fighting to the white-hot stage, and their own troops have suffered heavy casualties, so they really have no choice but to pull up the number of people.

The key to whether a civilization is strong or not is the regular army that is stationed there.

Therefore, what Luo Ji wants now is a regular army that is stationed in the military camp and trains every day.

Instead of those militarized training for a period of time, they will be put back in their hometown, what should they do.

After a few years, he forgot all his skills, and at the same time drank a beer-bellied reserve.

But within the civilization of the Ten Thousand Realms, the age meets the requirements, and the willingness to be a soldier is basically accepted by him.

Now I want to expand my troops.

He had only one way left.

That is, to send an expeditionary force as it did at the beginning.

Expedition along the way, while exploring the terrain and drawing maps, all the tribes found along the way were incorporated.

Then the people who meet the requirements will be recruited.
