When Roland received this report, which was jointly signed by the top leaders of the First Army and the General Staff Department, he immediately thought of the classic plots of those spy war movies.

Clearly, this is a highly feasible option.

He even thought more than Edith.

Although the profession of spy has been known since ancient times and has been called differently at different times, the concept and image that he is familiar with did not gradually take shape until the First and Second World Wars. In the past, most of the information transmission was a simple two-line connection, and there was no strict system developed. It became complex and systematic as government agencies gained more and more control over the people under their rule, and the eyeliner and spies became more and more difficult to survive.

This also means that the loose control system ruled by the feudal lords is fundamentally unable to eradicate the existence of spies. As long as the spy personnel are trained in some basic professional knowledge, and the upper and lower lines are cut off, according to their weak anti-intermediary consciousness and methods, even if they turn the whole city over to find it, it is impossible to touch the tail of the lurking person.

After all, for those downlines who provide information, the upline is simply a shadow figure who has never been seen before, and if they are replaced by nightingales to interrogate, they can't ask anything.

Roland immediately approved the plan.

However, he did not intend to leave the matter completely in the hands of Edith, it had nothing to do with trust, but espionage required a lot of energy to plan and arrange, he valued the strategy of the Northland Pearl and the extremely rare overall situation thinking in this era, if he used his energy on this kind of thing, it would be a bit of putting the cart before the horse.

Professional things can be left to professional people to do.

He spread out a new piece of paper and wrote Hill Fox's name on his letterhead.

The political situation in Dawn has basically stabilized, and this circus director should be a little bored, right?

After asking Nightingale to deliver the letter to Honey, Roland began to think about something else.

That's the intelligence network.

At the beginning, the news he had to deal with, whether it was war or political affairs, was basically limited to the territory of Gray Keep. From the beginning of the expedition to Tachira, there was a noticeable delay in the flight of the messengers, but fortunately the Seagull glider was able to travel to and from the front line in a day, which was acceptable as a relay supplement.

But now that the main battlefield has become Wolf's Heart and Eternal Winter, the inconvenience of communication is particularly prominent.

For example, the report at hand was delivered to me by sea, but the payment date was a week ago. Answering with an animal messenger will be much faster, but two or three days will still be inevitable. What's more, the courier who can fly long distances of more than 1,000 kilometers does not have much control over honey - after all, she can only make the animals obey her orders, but she cannot change their own inherent habits.

What's more, even for short-distance messengers, there is a limit to the number of messengers, and the magic of honey is not enough to support the communication needs of the entire western border, let alone the whole country and beyond. When those spies start operating, how to transmit information safely and quickly is also a major problem that needs to be solved urgently.

Roland knew in his heart that the ultimate solution was radio transmission.

The principle of wired telegraphy is simpler, but it is limited by the attenuation of the line, and it is not fundamentally different from the telephone used today, even if the distance is doubled, it is only 100 kilometers, and then it is necessary to add a retainer - such as an electron tube and other things that can amplify the signal.

The problem is that if he can build an electron tube, the radio will no longer be out of reach. You must know that there is no concept of electromagnetic pollution at all in this era, and the modulated electromagnetic waves are simply like the cry of a baby in the silent night.

If he succeeds in making a wireless telegraph, it will only take a few minutes for a report from the front line to reach his desk, and if he goes a step further, it will be as strategic as the Dawning Project if he can assemble a portable wireless telegraph for the entire army.

Of course, it was clear and clear, and as for what to do, he didn't have a clue at all.

Maybe it's time to find a few more projects for the Greycastle Design Bureau, Roland thought to himself.

......

After entering the dream world at night, he first sent off Jieluo, who went to school, and then drove to the three-leaf construction site on the outskirts of the south of the city.

I have to say that Guardian is indeed a very cheerful businessman, as long as it is promised, it will be implemented as soon as possible. The other party not only handed over the management of the factory to him, but also gave him a set of maintenance services, including repainting the rusty walls and columns, replacing new office equipment, etc., without any perfunctory meaning.

If it weren't for the fact that the Shamrock Group was always unwilling to give up the land in the Silolou community, Roland would like to deal with such people more.

He parked the car and found something strange in the open space outside the factory, which was rarely visited by people in normal times, but today there are many more construction workers.

At the same time, he heard a series of dull roars, as well as the characteristic sound of the reciprocating impact of machinery.

Roland walked briskly through the crowd and saw a strangely shaped tracked machine appear in his field of vision - it was clearly a half-finished machine, only the part of the ground was finished, and if you just looked at the tracks and load wheels, it was nothing special. The reason for this is the obtrusive steam piston system above it, and the other tractor that supplies it with steam.

Seeing this scene, Roland couldn't help laughing.

It turned out that this was the method that Master Xie came up with - in order to minimize the impact of the imaginary boiler and water tank, he installed all this part of the equipment on another tractor, and the two had to be tested in parallel before the steam engine could run. In the eyes of outsiders, it is equivalent to a tractor not only to ensure that it can move, but also to provide power to another test subject, which is similar to the "solar flashlight" that can only be lit when there is light, and absolutely not lit without light.

"Ahem...... Boss, you're here. Master Xie also seemed to think that it looked stupid to do this, and greeted him with a little embarrassment.

Roland praised unappreciably, "Good job, this is exactly what I want!"

He came to the factory almost every other week to check the progress, and the last time he came, the planned tractor was only an empty shelf, but this time he was already able to run on its own, which shows that the other party has really put a lot of effort into the project.

"Yes...... Really?" Master Xie touched his bald head, "Are you sure those collector friends of yours would be interested in this kind of thing?"

"The body parts of the test were all machined on factory lathes, right?"

"Yes, I can guarantee that. Master Xie hurriedly rubbed his hands and said, "But the other tractor, boiler, water tank and other equipment are all ready-made second-hand goods, and they have almost cost more than 300,000 ...... so far."

"Money is not a problem," Roland said with a wave of his hand, and someone cushioned it anyway, "as long as it is handmade, my friend will definitely buy it." Work hard, and when this business is done, I will give you an extra month's salary!"
