"This is the third open-pit oil mine ever discovered."

Liaodong City.

Zhang Qi sat at the head of the case and said as if asking.

Offstage, Bai Xing rummaged through the rows of bookcases, compared the catalog and turned out the Liaodi Jinshi Record, opened the title page, found the information about the oil mine, and said loudly.

"It's the third one, and the team has also discovered a cuprite mine."

"Hmm."

"There are more and more mineral deposits, these are the background, reply to Lu Qi, after the snow melts in spring next year, people will go to predict the amount of minerals, since the location is close to the Beiliao Passage, then let the deer herders participate."

"Let Lu Qi organize manpower, build a railway to pass, choose a suitable place, build a city, and migrate people."

"A piece of copper, a piece of oil, is worth the investment, not to mention the amazing treasures contained in that land that is even wider than the land of China."

"Huh. That's the eldest son of the earth, although it's a little easterly. ”

As Zhang Qi's most intimate secretary, after Qingling gave birth to Qilin'er, Bai Xing served Qingling's mother and son for almost four years.

"You seem to care a lot about this thing called oil?"

has not been by Zhang Qi's side for four years, but Bai Xing is still as cold as when he first saw him.

Zhang Qi nodded at the head of the case: "It's really important, but for now, if you want to fully use the front-end technology, it is still not enough, and it can only be used to make some simple things." ”

Oil, the spinal cord of the earth, there are so many places to act.

Plastics and fuel are just the simplest ways to use.

And now Zhang Qi can only take advantage of these two directions.

Scholars in the world of internal combustion engine riding and slashing already have eyebrows, don't look at the outside world for less than ten years, but nearly two hundred years have been spent in the world of riding and slashing.

The scholars in it are now in their fourth generation.

The population was also 200,000 smaller, occupying the most abundant imperial city in Calradia.

Moreover, supplemented by the accumulation of the outside world under the development of Zhang Qi in the past eight or nine years, the development of materials science can be said to be changing with each passing day.

Just the metal that is harder than steel can be pulled out of five or six kinds of metal alone in the world of riding and slashing.

With the accumulation of materials science and the assistance of Zhang Qi's knowledge, the technology trees in the riding and chopping world were lit up one by one.

As I said last time, Huo Quai's expedition may be the last cold weapon battle under his command.

And that's exactly what happened.

On top of the case, Zhang Qi put the last document that officials could not call the shots with slogans and seals, and then got up.

"Let the post pass on these pieces back to the places, and let's go to the school."

As he spoke, he bent down and took out two iron rods from the drawer at the head of the desk, which seemed extremely strange in Shirahoshi's eyes, and crossed them behind his back.

"Yes."

Bai Xing put away the few letters on the head of the case, and then followed Zhang Qi out of the Taishou Mansion.

"Three hundred miles of urgency, hard work."

After leaving the Taishou Mansion, Bai Xing handed over these documents to the staff of the post office.

Although it is a cold winter and heavy snow, with a dog sled, Liaodi Post can also complete the post mission in winter, but the speed is not as fast as other seasons.

After arranging the post staff, Bai Xing sped up his pace and caught up with Zhang Qi, who had already reached the end of the street.

"Huh——, Your Excellency."

Hearing the movement behind him, Zhang Qitou didn't reply: "Arranged it?" ”

"It's all instructed."

"Your Majesty, is there something new coming out?"

"It's . weapons? ”

Bai Xing's eyes looked curiously at the iron rod that Zhang Qi was carrying behind his back.

The stick is round and straight, with a hole in the center, and the position of the hole at the very front end has a lookout similar to that of a crossbow.

At the rear end, there is a trigger firing device similar to that of a crossbow.

Shirahoshi guessed that it might be a weapon used to attack from a distance, but she couldn't figure out how to do it.

Zhang Qi chuckled and glanced sideways at Bai Xing: "It is indeed a weapon, you will know later." ”

The school field of Liaodong City is not far from the Taishou Mansion, it is a small school, the main purpose is to store armaments, and the permanent strength is only 800, which is considered an urn city in the city.

The colonel is outside the city and can garrison more than 20,000 troops, but at present, Liaodong belongs to the inner hinterland, so there are only 2,000 people to maintain law and order in the surrounding areas.

As for what Zhang Qi is carrying, it is the firearms commonly used in modern warfare.

It's just that one of them is a smoothbore gun, and the other.

It's rifled guns!

The rapid development of materials science has created the industrial foundation in the world of riding and chopping, and the milling machine has long been introduced, and with a little modification, it has become a rifling machine that can be pushed back and forth, the gear angle is adjusted, and the crank wheel controls the rotation, and.

The machine is also steam-powered, does not require manpower, and often a single skilled worker can take care of four milling machines at the same time.

However, Zhang Qi has not yet prepared a large-scale rifled gun, and still chose a smoothbore gun, a large part of which is not because of production capacity, the production of rifled barrels is enough to ride and chop the world, and it is not difficult to do, but this is because Zhang Qi has opened the era to hang on the wall.

Rifled guns can be built, and the production capacity is sufficient.

The factor that prevented Zhang Qi from loading them was ammunition.

Until now, Zhang Qi still hasn't figured out how to mass-produce bullets, even in his previous life, he can't find much information, so he can only rely on Seiko to rub it by hand.

So rifled guns, he planned to equip only a small number of guards around him.

Large-scale armaments in the army are still smoothbore guns.

After all, the projectiles of smoothbore guns are easy to handle, whether they are lead bullets or metal bullets, and rounding them is a breeze for today's Liaodi.

To put it bluntly, a smoothbore gun is a scaled cannon, and in the same way, the process of making cannon ammunition is also suitable for smoothbore guns.

After a while, Zhang Qi and the two arrived at the school.

At this time, it was the morning, and the intensity of the winter army training was not high, and it only needed to last ten days a month, so there were not many soldiers in the school field.

After Zhang Qi entered, the shadow guards behind him also rushed in, clearing an open space and guarding the surroundings to prevent others from passing by.

The target of archery practice is erected.

Paste the target paper that Zhang Qi had prepared a long time ago.

Under Bai Xing's curious gaze, Zhang Qi took off the rifled gun, took out a finger-thick bullet and half-finger-length bullet from the pocket on his waist and stuffed it into the chamber.

Aim.

Three points and one line.

The whole body strength is completely prevented from possible recoil.

Syllable!

Like a thunderclap on a winter day.

Standing on a concrete floor that had been cleared with only a thin layer of snow remaining, surrounded by white smoke.

Frowning, Zhang Qi murmured in a low voice: "The ratio of gunpowder is not right?!" ”

"How the hell is smokeless gunpowder made?!"

Shaking his head, he looked at the target, which was twenty meters away from him.

"Fetch it!"
