Luo's voice is undoubtedly causing Ye Hao's attention.

Jiang Zhan, when they saw Luo, they all came to salute.

There is also obvious tension in the expression.

Obviously, Luo Ji’s coming is too sudden.

In comparison, Ye Hao is not so constrained.

Although Luo Ji is now a high-ranking emperor, but in the face of Luo Ji, she still does not produce much tension.

Because the two have known each other for many years, how can it be unclear to the character of Luo Ji, who followed him all the way to the present?

Attention was immediately transferred to the words that Luo Ji just said.

"Your Majesty, you just said back to the cannon? What happened to the returning cannon?"

Luo Ji is not surprised at Ye Hao’s reaction.

After arranging the thoughts in my mind, I only listened to him slowly...

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

During the speech, Luo Ji said his understanding of the returning gun.

Back to the cannon, although with a 'cannon' word, but actually has nothing to do with the firearms.

It is still a cold weapon.

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

In fact, all the similar weapons are summed up in the three words of "the slinger", and there is nothing wrong with it.

Because of their attack method, it is a throwing boulders.

Of course, this return gun is obviously more powerful and range than the early catapult.

She took over the design drawings and reconstruction plans she had drawn from Ye Hao.

Luo Ji looked up and down slowly.

Large ordnance, the prospective head is not well controlled.

Parabolic heads with parabola are even worse.

It is very difficult to improve this problem.

He also has no hope.

Therefore, at the beginning, when Luo Zhi was called Ye Hao to improve the catapult, she mainly asked her to strengthen the power and range of the catapult.

The attack method of the catapult is based on the principle of leverage.

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

The explosive force of the lever is derived from its swing.

In other words, the greater the leverage.

The explosive power and inertia will be stronger.

The greater the range and destructive power of the boulder!

After having this idea.

Ye Hao naturally knows where to start.

However, increasing the swing of the slinger's lever is not as simple as that.

She and Jiang Zhan experimented and improved.

An ordnance is a whole.

Changed one of the component structures.

Then other parts structure has to be changed together.

Then changed it, and the catapult was changed by them.

Up to now, the basics have not seen the original look.

People who don't know, think they are doing new weapons.

For Ye Hao, their transformation direction, Luo Ji is undoubtedly given affirmation.

To be honest, Luo Ji did not think that they could change to this point.

His initial thoughts were just to improve it, and after adding some range and power, it was easy to use.

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

As a result, the two top ordnance engineers under their own hands are too capable.

The erroneous mistakes upset his original plan.

This is really a thing that makes him laugh and cry.

Since this is already the case, what else can you say?

This embarrassment really brought him no small accident.

Wait until you return to your place of residence.

Luo series directly brushed the auction floor.

Originally, I wanted to get a second-grade silver design.

But the auction site has been out of stock.

This thing is obviously very popular.

No way, I finally bought a black iron-grade 'return cannon' design.

Then I was sent to the Ordnance Research Department and sent over.

Immediately after that night, he was insomnia...

I suddenly fell asleep when I slept in the afternoon.

So that he can't sleep at all.

In the end, he had nothing to do. He simply opened the system page and researched his own development panel.

With the rapid development of Wanxiang civilization, there are more and more development projects in the development panel.

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

I have to say that this is really a good way to pass the time.

Enough to kill his time.

After a round of additions, Luo Ji, leaning against the bed, glanced through the window and looked at the sky outside.

Obviously it is still early in the morning.

However, the brain has undergone sufficient thinking activities.

Instead of being sleepy, he is now more awake than before.

If this is in the real world, he estimates that he will simply open the computer to play the game.

Then greet the sunset of the next day in the next round of non-stop...

As for now.

Luo Ji left his bedroom.

Sitting under the watch of the guards, ‘I know,’, sat at the desk of my residence.

Although there is no work paper that has not been piled up waiting for him to deal with it.

However, Luo Ji feels that he can sort out the development plan afterwards.

The development project of the North Mountain Forest ~lightnovelpub.net~ the territorial expansion plan on the grassland.

The construction of Qingcheng City in the late city.

Sewer construction projects in dozens of cities.

The further popularization of glass greenhouses.

There is also the place of bitter cold.

Since it is necessary to probe steadily, he feels that it is necessary to temporarily clean up a frontline camp out of the periphery of the bitter cold.

What is listed in Luo Ji today is only a few major projects within the Wanfang civilization.

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

At the same time, the total strength of the territory.

Although the system of 'serving military service' has already been promoted.

Now there are already two groups of reserve soldiers.

But in the end, there is no comparability between the reserve soldiers who have only been trained for a while and the regular soldiers who train every day.

To put it bluntly, the reserve soldiers are fighting to the stage of white-hot, and their own casualties are heavy. There is really no way to pull them up to make up the number.

A civilization, the strength of the military is not strong, the key is still on the regular army.

Therefore, what Luo Ji wants now is the regular military camp, the regular army training every day.

Instead of those military training, after a period of time, put them back to their hometowns, why should they do it.

After a few years, what was forgotten, and also a reserve of beer belly.

It can be within the boundaries of the Wanfang civilization, the age meets the requirements, and the basics of being willing to be a soldier are almost the same.

Now I want to expand my strength.

He has only one way left.

That is to send the expeditionary force as it was at the beginning.

All the way to expedition, while exploring the terrain, drawing maps, all the tribes found along the road are compiled.

Then fill in the people who meet the requirements.
