During a cross-country training, Marin was there to detect the terrain, but found that the distance seen by human eyes was limited, and it was impossible to see clearly when the distance was far away. So Marin remembered the telescope...

The telescope was invented in the early 17th century, and it is still more than a hundred years away. Marin had to find a way to create a "invention" by himself...

Of course, as an advanced technology and a very strategically important advanced technology, Marin was not willing to let others know about the existence of telescopes. So he went to the glasses shop in Robach town, looked for the craftsmen in the store, and polished a batch of round concave lenses of the same size. Then, he rode to another town, found a local glasses shop, and asked the glasses craftsmen in the store to polish a batch of convex lenses (magnifying glasses) of similar specifications for him.

Then, he went to Vienna and found a craftsman who was good at making wooden crafts. He created a batch of wooden barrels for him. The front and rear ends of the wooden barrels are disassembled spiral lockers, which can fix the polished lenses.

Of course, in order to hide the lens, there is a length of wooden barrel in front of the locker, so that people cannot see the glass inside. If you are not careful, when Marin looks away with a telescope, others think Marin is observing something through a wooden barrel.

However, what made Marin depressed was that the quality of glass in this era seemed to be poor. Ordinary glasses were a little green. This was because the iron ions in the glass were not removed, so the transparency of the glass was not very good. The earlier optical glass, lead glass, seemed to have appeared in Britain only in the 17th century.

So, Marin can be sure that telescopes of this era will not look too far. Because the clarity of the glass is not enough...

Sure enough, after Marin received the goods a few days later, he assembled the telescope himself, which could draw a long wooden barrel and adjust the focal length. However, no matter how Marin adjusted, the telescope's distance was no more than 5 kilometers. No matter how far it was, it began to blur. Even at a distance of 5 kilometers, it could only be distinguished and could not be seen clearly. Of course, this was much better than seeing the enemy situation with the naked eye.

After assembling the two telescopes, Marin bought two wooden boxes and locked the telescope. The keys were only owned by themselves and others could not open them. Even if Kahn and others did not know what they were.

Later, in order to cultivate Schwartz (actually Marin decided to be lazy and let Schwartz do some daily work on his behalf), Marin organized several group confrontations. The confrontation was mainly carried out in the mountains, and Marin also took out the tactic of ambushing the mountain commonly used in the East. However, he did not dare to use the trick of smashing stones on the mountain, because this would kill people.

Schwartz took the people hard and carefully made a long detour, and then quietly touched the camp where Marin was guarding. But what he didn't know was that at the height of the camp, Marin had already used a telescope to figure out his troops deployment and march direction 5 kilometers away, and made corresponding adjustments.

When Schwartz's 50 people touched the camp, they directly faced the traps and encirclements under Marinbu...

The others didn't understand, but Kohler, who had not participated in the war, seemed to understand it a little - it seemed that Marin could make corresponding subordinates, which was related to the two cylinders he locked in the box. However, as a servant, he was not easy to inquire at will, nor could he do so. The depressed Schwartz didn't understand why Marin could "predict the enemy's initiative". Then, Schwartz admired Marin more and more...

After several exercises, Marin seemed to notice Kohler had noticed the cylinder in his hand. So he felt that the cylinder in his hand seemed too conspicuous.

So he found a craftsman again, customized smaller lenses and smaller and inconspicuous cylinders, and once again assembled a small telescope. This telescope is very small, and Marin can cover most of it with two hands, but it can also reach an observation distance of 5 kilometers. When Marin stood at a high place and used a telescope to look at each other, others saw Marin put his hands in front of him, thinking that his hands were used to block the sunlight... In fact, he was holding a small cylinder in his hands...

In fact, telescopes are the most useful for scouts. As the head coach, Marin can observe the enemy formation in front of the formation, but it is impossible to go out to investigate frequently (there are also head coaches who personally investigate, but the outcome is generally not good. For example, Li Zicheng went out to investigate personally and was KOed by unknown landlords. Washington personally investigated himself, and almost sniped by Colonel Ferguson...). So, after thinking about it, he decided to develop his attendant Sauer into a scout...

The reason why he chose Shaul was because the Shaul family was their own serfs and was more reliable than outsiders. Moreover, Shaul himself was very calm and his mind was not bad. Judging from the fact that he recommended Schwartz, Shaul was also a little wise. At least, he could look at people. Moreover, Shaul had good eyesight. In addition, when hunting, Shaul was often in the task of reconnaissance, and he had some experience in this. He could come back to report his position without disturbing the deer or wild boar, proving that he was very suitable for reconnaissance.

Moreover, in this era, scouts often had to go close to reconnaissance, which was very dangerous. If you were not careful, you would be discovered and chased by enemy sentries.

But after owning a telescope, the scouts do not need to approach the other party’s camp. They just need to find a high point a few kilometers away and take out the telescope to do it.

In an era when telescopes were not popular, even people with the best eyesight had to be within one kilometer to obtain some important data. Most people even had to be within a few hundred meters to see clearly. Therefore, even if people in this era had to be anti-reconnaissance, they would not exceed 1 kilometer away.

Therefore, as the first group of people to use telescopes to investigate, Saul's safety can generally be guaranteed.

Afterwards, Marin and Shaul had a private conversation. Marin tested Shaul's loyalty and found that it was not bad. Then, he made Shaul swear that he would never allow anyone to disclose any information about the telescope. Moreover, every time Shaul went out to investigate, he could come to him to get the telescope. Usually, the telescope used by Shaul was locked into Marin's box.

Not only that, Marin also demanded that Saul should not use telescopes in front of others to avoid being seen by others.

Sauer didn't care at first, but he was really surprised when he got the telescope. The first time he used the telescope, he was so scared that he almost threw the telescope.

"This...this is so amazing!" Saul was shocked.

"Okay, Sauer, remember, you will never be allowed to reveal the secrets of the telescope to anyone! Including your loved ones!"

"Yes, Master!"

"Also, don't drink too much wine in the future. You can easily talk nonsense when you get drunk."

"yes!"

"Okay, go!"

In the next few days, Malin assigned several reconnaissance tasks to Saul and taught him how to hide himself. He also made him a camouflage reconnaissance costume.

After training, Saul completed the task better than once. In fact, this task is also very difficult. If you peek with a telescope a few kilometers away, no one can do such a thing. The key is to choose the right position to avoid being discovered by the other party. Moreover, it also requires patience to investigate. Fortunately, Saul is a very patient person. If he is as anxious as Kahn, he will definitely not have so much patience to stay there and slowly count the number of people, the number of animals, the in and out of the carriage and horses.

Of course, this involves knowledge of reasoning and calculations, and Saul is definitely not at that level. What Saul can do at present is to estimate the number of people on the other party through the house/tent, and to infer how many pots the other party has through the number of smoke rising during cooking, so as to simply infer the number of people on the other party eating...

These are the basic principles, and Westerners in this era prefer to fight head-on, and at this time they will never come up with any strategy of "reducing the stove and luring the enemy". This estimation is relatively accurate.
