The so-called spies are actually scouts. Pen %Fun %Pavilion www.biquge.info This seemingly easy class of troops actually determines the combat effectiveness of a unit in a large sense.

All spies are not only veterans, but also must be both civil and military.

Speaking of the text, it's not just a matter of knowing a few words, more often you need to decipher the other party's intelligence.

With the exception of a few letters, almost all information will be replaced by ciphers, which requires spies to have a lot of practical experience in addition to having a good mind and reaction.

Not to mention the martial arts side, before the warring parties actually met on the battlefield, there were often several exchanges between the spies of the two sides.

If the battlefield where the two armies face each other is hell on earth, then the battlefield between the spies is the real purgatory.

The difference between the two is that even in the most tragic battles, there is always someone on the losing side who survives. And once the spies meet, the loser has only one end, death.

It seems to be a silent tacit agreement between the spies, and only when one dies will the other leave. In their eyes, there is never such a thing as a lose-lose situation, and the death of both is a common result.

This is the real life and death, fighting for who can send the information back alive, and the side that dies, in addition to losing their own lives, will also lose the information, so that their side is in an extremely passive situation on the battlefield.

Therefore, although when the army is fighting, except for special circumstances, these spies do not need to be on the battlefield in person, in fact, their fight has already begun quietly long before this.

In addition, there is the most important criterion for evaluating the ability of a spy, that is, how large the scope of investigation he can control.

The two armies fought, except for the moment when they clashed on the battlefield, the rest of the time, the soldiers on both sides were almost in a state of leisure.

And only the spies on both sides are busy all the time.

When a team is on the move, it is necessary to ensure at least that all the wind and grass within ten miles must be notified to the commander at the first time, and if it is a marching army, this range must be at least twenty miles or more.

These are just the basic requirements for ordinary spies, the better spies, the detection range is about thirty miles, and the top spies can even reach fifty miles.

Since the spy in front of him can detect the movements of Cao Jun thirty miles away, it means that he can almost be called a top spy. Judging from the anxious look on his face, Liu He knew that this Cao Jun must be fierce.

"How many stoves does the enemy have?" Han Yi asked calmly.

For Han Yi's strange question, Liu He, who has been in the army for many days, is not surprised.

When spies inspect the enemy camp, in addition to the movement of the enemy army, the most important thing is to find out how many troops the enemy has.

When making food during the march, ten people are a stove, and counting how many stoves the enemy has set up is equivalent to knowing the opponent's strength.

Although there will be some small errors in this method, if you count the heads one by one, I am afraid that you have not counted them clearly, and your own base camp has already been served by the other party.

Moreover, a man is alive, but the stove is dead, and it is much faster to count the stove on the ground than to count the head. Therefore, under normal circumstances, spies use this method to judge the enemy's strength, and it is also a habit they have formed over the years.

Han Yi, who has led the army to resist the officers and soldiers for many years, naturally knows the doorway.

"About three thousand stoves in the morning," the spy hesitated, "and by the time I leave, there will be at least five thousand." ”

Han Yi frowned, "It seems that the enemy army is gathering, and there is a steady stream of follow-up troops. ”

Liu He secretly calculated to himself, and couldn't help blurting out, "The enemy army has 50,000 people? ”

Liu He knew that Cao Cao would send a large army to chase and kill, but he didn't expect that Cao Cao would send an army of 50,000 to his side.

Han Yi smiled bitterly and shook his head, "Mr. is wrong this time, it's not 50,000, at least 80,000." ”

Liu He was shocked, "Eighty thousand? Ten people have one stove, and five thousand stoves are not 50,000 people? How could there be another 30,000 for no reason? ”

Han Yi waved his hand and ordered the spy to investigate again, and then said to Liu He: "This account is not calculated like this, although it is common sense in the army to have ten people in one stove, it is not applicable to the troops that are being assembled. In the early morning, there were only 3,000 stoves, which was indeed 30,000 people, but now an hour had passed, and when the spies left, another 2,000 stoves were added, indicating that the second group of troops arrived was 50,000 people, because the first batch of 30,000 people had already eaten up, and the stoves they had used had already been used twice. ”

Liu He suddenly realized, "That is to say, even if the stove is no longer increased, there is no guarantee that the enemy army will have no other troops besides these 80,000 people." ”

Han Yi nodded, "That's exactly the case, so I said that there are at least 80,000 people, and only a lot more, the specific number can only wait for the spies to investigate, or we can go and see it ourselves on the battlefield." In my estimation, it will be around 100,000 people. ”

Liu He's brows furrowed after hearing this, and he naturally believed Han Yi's words.

The enemy has an army of 100,000 and less than 10,000 himself, and with such a huge disparity in strength, if you meet the enemy head-on, it is tantamount to hitting a stone with an egg.

For today's plan, there is only one word, run.

But once the march is accelerated, it is equivalent to leaving behind those people, how can this be good?

In a hurry, Liu He had no choice but to turn to Han Yi again, but Han Yi kept silent from then on.

Liu He suddenly understood, it seemed that Han Yi had something to say that he couldn't say in front of outsiders. Liu He immediately jumped out of the carriage and suddenly looked back, are these two ladies also outsiders?

But at this time, Liu He didn't have time to take into account the feelings of the two women anymore. He turned over and got on his horse and glanced at a few people around him, and a few people in the Tianji Camp instantly expanded the circle, blocking other unrelated people from Liu He and Han Yi.

"Time is pressing, we are all our own people, don't go around in circles. I just want to know how we can speed up the march and get rid of Cao's army. Liu He asked straight to the point.

"With these people, it can't be fast." Han Yi said calmly.

Liu He was silent for a moment and sighed, "You mean to say that you can only throw these people behind?" ”

Han Yi shook his head, "No, it's because of these people that we can't speed up the march. ”

Liu He breathed a sigh of relief, and a relieved smile appeared on his face.

Although he knew that taking these people would greatly slow down the speed of the march, if Liu He was allowed to leave the people and flee alone, he couldn't bear it.

Seeing that Han Yi also had the same idea as himself, Liu He was finally much more down-to-earth, but Han Yi's next words shocked Liu He.
