As the elf, whose eyelashes were covered in frost and looked like he had returned from an extremely cold hell, began to attract the attention of passers-by from the city gate, and then walked into his office with a big grin, stuffing the freshly baked pizza into his mouth one by one.

Leo is sure that the elf is a canine creature, at least this one, but he is embarrassed to compete with her, and in the past two days, it has begun to be rumored that he is the black-hearted boss, and he doesn't know who let it go.

Unfolding the map in front of him, which was almost crumpled into a ball of waste paper and still carrying oil, and wrote down the coordinates on the summary sheet, this time discovering the canyon terrain, and the traces of iron ore and coal mines could be found just by looking at it with the naked eye.

However, according to Durandal, there must not be just this kind of ordinary ore vein, that kind of rich earth breath must be emitted by some kind of elemental ore vein.

It's just that mining has become a problem, there are mines in the north, and this is a matter that has been determined from the beginning, but why only Blackstone Town has been developed so far is because only Blackstone Town is on the underground fire vein, there are natural hot springs, and the surrounding valley terrain can prevent cold wind erosion to the greatest extent.

The other workers weren't as rough-skinned as Durandal and couldn't run wild on snowy mountains in such weather, let alone mine veins in the bitter cold.

"Well..... of course no one else is so edible."

Durandal's mouth was stuffed with food and he could only express his displeasure by humming.

There is also disturbing news from the direction of the Eastern Front, and the army of the dead with wisdom will probably end in a disastrous victory with such a setting.

Naturally, Leo doesn't want it to happen, he needs to be a bloodless victory, not a miserable fight back after being beaten at home.

At this stage, you can't get more powerful explosives, and you can only try to see if you can improve the musket, and the reload and excitation speed of the imitation 98K is hard.

In the future, when facing hundreds or thousands of undead armies, a weapon that can fire continuously is particularly important, but unfortunately only the revolver can be achieved now, and the maximum is nine rounds.

How can guns not last!

But I only have a general understanding of this aspect, and I vaguely remember that it is to use the aerodynamic force of the gunpowder itself to complete the steps of unpacking and loading.

Write down the general principle, and let the institute find a way to achieve it as usual, since the establishment of the Drifting Snow City Research Institute, the average hairline of all scholars and craftsmen has receded by more than two centimeters, and the prices of foods such as black sesame seeds and ginger have risen well recently.

In the end, Leo decided to go to the second mine in person, and naturally everyone wrapped themselves in a ball before going up the mountain, and the situation may not be so bad after the field investigation.

The wind and snow are only on the canyon, and the convection is not formed under the canyon because of the mountain, so if you build a base directly in the canyon step by step, the coal mine is enough to support the site for basic refining, and it can also supply energy for the floor heating system.

Only Egger foresaw the tragic future of his monthly field research, in addition to going to Blackstone Town, to this ice valley where birds don't and being half frozen.

"Teacher, the measurement results here are out, the height of the two sides is basically equal, unless the bracket is built to the top of the mountain, it is impossible to realize the cable car transportation"

As for the work efficiency of Lac, the field survey has been completed in just half a day, but the transportation has indeed become a problem, the location of the second mine is not as good as Blackstone Town, and the distance is not good.

The development of vehicles in Drifting Snow City has always been in a state of not being embarrassed or embarrassing, and the snowmobiles with simple structures are constantly innovating, but they have never been able to change the routine of walk-behind tractors.

Before the large transport vehicle was built a stunned no one dared to drive, in the end it was the rough-skinned Bell took the initiative to ask for help, and after the brakes failed, he decisively abandoned the car to escape, and finally found the wreckage of the prototype truck three kilometers away from the jump point.

The wind tunnel experiments assisted by Lahr have not even built a model airplane so far, and it has been idling for many years.

There is no need for a meeting, everything is decided long before the meeting starts, a certain sage once said, and Leo, who was holding the teapot and shrunk at the end of the desk, silently listening to the development team's chickens and dogs, thought deeply of this sentence.

"Do you want to build a railroad?"

"Didn't you say you couldn't bring it anymore, there is still no movement on Eyre's side, and the things in the parts factory have been cutting corners recently, and the bolts have raw edges."

"In the end, it's not that there is no progress in engine development, what do you do every day with such a large ration?"

"You think the engine is cabbage! And what the hell do you chemistry groups eat! What about gasoline! No gasoline comes to your N's gasoline engine! ”

Al was originally a pure teenager, and he was coarse with these big guys all day long, and he was finally poisoned, and even the recent quarrel between the scholars and the family was inseparable from the female family, what happened to the world.

The topic started to stop working, and Leo felt that it was time for him to start putting it in handy, and he couldn't be a mascot every day, right?

"Why don't you ..... just cut corners?"

It's still scary to sweep the eyes of a row of people who brush over, and Leo can only silently say in his heart that he can't be cowardly, I'm the leader!

"Like designing a ....... tractor with rails? It's okay to have a low load, you can send a few more cars.."

The more Leo said, the lower his voice became.,Recently, the development team's painting style is wrong! Did you force yourself too hard, why did you all have the posture of a middle-aged oilhead supervisor.

"This should be possible!"

Al was the first to speak, quickly calculating the power load in his notebook, and the others began to consider the specific feasibility of the plan.

After all, people are still easy to drill the tip of the horns, why didn't I think of this trick before, heavy trains can't be built, and it's still possible to build a light cargo pulling equipment.

Minecarts can also be hand-cranked, and this steam engine can also bring two or three truckloads of goods again.

The core problems were solved, the basic plan and construction plan were also made as quickly as possible, and the planning and construction could be completed in a week.

"This still needs to be driven, right? Someone has chosen it, it's not easy to travel between these two places."

"Don't worry, I already have the best candidate, you just need to come up with the plan and put it into construction as soon as possible."

Seeing that Leo looked confident, no one asked more, but a certain elf in the central building couldn't help but sneeze, and Mei handed over a cup of hot tea with a worried look.

"You can't catch a cold, do you?"

"I've never seen a cold in my clan when I'm so old, who is talking about me?"
