"Zhang Du, where's Yutu?"

Seeing Zhao Xu speak, Zhang Tingyu glanced at Gao Yi.

Gao Yi hurriedly stepped forward, unfolded the map, spread it on the desk, and said solemnly: "Lord Wang, this is the map near the suburbs of Beijing, and the location of Jingshan is on the northeast side of the map. ”

Looking at the map spread out on the desk, Zhao Xu's eyes were slightly condensed.

"Lone transferred some files related to this group of bandits from the Criminal Department, only to find out that not only the past merchants, but even the counties around Jingshi have been attacked by these bandits."

As he spoke, he took a charcoal pen made of willow wood and lightly drew a circle on several county seats.

"Judging from Gu, this group of bandits has been able to entrench around Jingshi for such a long time, and there is a good chance that there are eyeliner buried in the county seat and even in Kyoto."

This gang of bandits robbed merchants who came and went, and there was no shortage of money in their hands, and it was not a difficult thing to use some small favors to buy off the officials and officials in the county.

They don't need these officials to do anything, they just need to notify them when there is a movement in the court to suppress bandits.

When Zhang Tingyu heard this, he said with a gloomy face:

"What the prince said is that it is no wonder that every time the Beijing camp goes out to suppress the bandits, this group of thieves hears the prophet and slips like rabbits, and before the army arrives, they hide in the deep mountains and old forests. This Jingshan Mountain is more than 200 miles in circumference, and tens of thousands of horses in the Beijing camp are thrown into it without a sound......"

Zhao Xu nodded, took out a few files from the corner of the desk, handed them to Zhang Tingyu and Gao Yi, and said:

"Governor Zhang, Lieutenant Gao, these files record the records of past merchants who have been robbed by bandits in the past month."

The two took it, looked at it briefly, and nodded their heads.

"But, my lord, with all due respect, what's the use of these files?"

Gao Yi had a puzzled look on his face.

Zhao Xu explained with a smile:

"There is a saying that people have left their names, and geese have left their voices. In the king's view, the crimes committed by these robbers are just clues, and when taken together, we can deduce the location of the thieves' lair. ”

When Zhang Tingyu and Gao Yi heard this, they couldn't help but look at each other.

Is that what these eight words mean?

Also, how easy is it to find out the thieves' lair?

Looking at the big words "disbelief" on the faces of the two, Zhao Xu smiled slightly, and used a charcoal pen to mark the locations of several thieves on the map.

"Look, here, here, here, and here, these four places are the closest places for this gang of bandits."

Looking at the four locations marked by Zhao Xu on the map, Zhang Tingyu frowned, and after thinking about it for a long time, he didn't come up with how to deduce the location of the thieves' lair by relying on these locations alone.

"Governor Zhang, these few times the Beijing camp has been dispatched, it will not be completely fruitless, right?"

Seeing the look on Zhang Tingyu's face, Zhao Xu asked with a smile.

Zhang Tingyu sighed and said:

"If this is the case, Your Majesty wants to abolish the Beijing camp, then the Governor has nothing to say. In these few crackdowns, although they failed to find the thieves' lair, they finally caught a few thieves. However, the families of these thieves are all in the thieves' nest, and it is impossible for them to tell the location of the thieves' nest, even if it is under heavy punishment. ”

Gao Yi nodded and added:

"Jingying also wants to pry a breakthrough from these thieves, but unfortunately, these guys only know how to go, but they can't even tell the difference between southeast and northwest."

Zhao Xu stared at him and asked:

"So, have you ever asked these thieves how long it will take to leave the thieves' nest and then come to the ambush site?"

Zhang Tingyu frowned and thought for a while, and said:

"Those guys used to say that when they left the thieves' lair, it was almost the sun that had just risen, well, it should have been around midnight, and when they arrived at the target location, they laid an ambush, almost just past the middle of the day, that is, around the middle of the day."

Zhao Xu secretly calculated in his heart, from the beginning of the hour to the end of the hour, that is, about five hours.

Zhao Xu nodded, raised his hand and took down another file, handed it to Zhang Tingyu, and said:

"Governor Zhang, please see, this is a copy of these files selected by Lone, which records that a group of merchants passed through Jingshan and was ambushed by bandits in less than four quarters."

Zhang Tingyu took it and flipped it through carefully, with a glittering light in his eyes.

"There are many wild beasts in Jing Mountain, and no matter how bold these bandits are, they dare not wander in Jing Mountain at night. Compared with the previous confession, these robbers should have set off from the lair at dawn and arrived at the crime site almost every four o'clock, and happened to meet this group of merchants before they started to loot. ”

Wu Song, who was on the side, couldn't help but add:

"During this month, it was about the middle of the day at dawn, so it took these robbers a full four hours from the lair to the place where the crime was committed."

Zhao Xu was very satisfied with Wu Song's answer, raised his hand and circled another location on the map, and said:

"Very well, with this, and a few other necessary conditions, we can deduce the location of the thief's nest."

Prerequisite?

What does that mean?

Seeing Zhang Tingyu and Gao Yi looking at him suspiciously, Zhao Xu, who was in a good mood, waved his hand and said:

"You don't have to worry about words, solving problems is the key. According to the confessions of those people, these thieves alone have about seven or eight hundred men, plus the women, children, old and young who have looted, there are at least more than 1,000 people in the thieves' nest.

With so many people, even if the thieves cultivated the fields in the mountains, the food produced would not be enough for these thousand people. In addition to this, they also had to sell the stolen goods, exchanging them for clothing, salt, weapons and other common items.

For this alone, it is impossible for them to build a nest in the depths of Jingshan. ”

When Zhang Tingyu and Gao Yi heard this, they couldn't help but nod their heads again and again; Even Lin Chong and Wu Song, who were guarding the door, showed approval in their eyes.

Seven or eight hundred thieves, plus women, children, old and young, these more than 1,000 Dingkou, all of them enter the deep mountains and old forests, whether it is the sale of stolen goods or daily life, it will become extremely troublesome.

Therefore, the lair of this group of thieves is neither too far nor too close to several trade routes.

"High school lieutenant, ordinary soldier, walking the mountain road in this Jing Mountain, how far can you go in an hour?"

Zhao Xu stared at the map and asked without raising his head.

Gao Yi's heart moved, and he seemed to have figured out some flavors, and said busily:

"Ordinary soldiers in Beijing, the cultivation is about four grades, and the mountain road of Jingshan can walk about ten miles in an hour. Even if there are strong people among these thieves, their overall strength is still inferior to that of the soldiers of the Beijing camp, even if they are used to walking mountain roads, they will only travel seven or eight miles at most in an hour. ”

Zhao Xu pondered for a while, pointed to the first four places circled on the map, and said:

"With these four locations, estimate the approximate distance, and find the intersection between the four points, nine times out of ten is where the bandits' nest is located."

As he spoke, he pointed to the last circled spot and added:

"The information on the location here is the most certain, and the previous intersection range, plus the overlapping parts, should be confirmed. Of course, the focus is on the side of the official road. ”

Zhang Tingyu's pupils widened suddenly, and he subconsciously turned his head to look at Gao Yi, but found that the other party also had an unbelievable expression.

Both of them are veteran generals in the army, and after Zhao Xu said that, they instantly understood the trick.

Not only Zhang Tingyu and the others, but even Lin Chong and Wu Song looked at Zhao Xu with a shocked expression.

They never thought that the problem that had plagued the Jingying army for so long would be solved by their own prince in just a few words!

Zhang Tingyu took a deep breath, clasped his hands into fists, and bowed deeply to Zhao Xu.

"Listening to the words of the prince is better than reading ten years of military books! Lord Wang, what a talent! ”

This King Ning, just these words made him see another world!

Zhao Xu accepted this gift calmly.

This is the integration of information in the previous life, which crushes all aspects of this era.

This way of thinking formed in the previous life is Zhao Xu's biggest golden finger in addition to the system!
