"Da Biao, how did you come up with this?"

Under the starlight, in the hidden mountains and forests of the assault company, Su Jigang came up panting, he first poured a sip of water and gave Zhang Dabiao a thumbs up, and his tone was a little excited:

"I went to ask people in nearby villages, and at first they all said that it was impossible, there was no trace of the flash flood, the path of each flood was different, and the water was fierce, how could it be possible to walk on it."

"But I listened to you, asked a few more people, and then asked an old man in the village, and this old man said that there is really such a waterway, or a mountain flood channel, you can walk by boat, and even float all the way down·····"

"But..."

Speaking of this, Su Jigang sighed:

"This mountain flood road is very dangerous, it requires a strong wooden boat to pass, and only the most experienced boatmen can run the boat, and there are very few people who know about it, but now the wooden boats have been seized or destroyed by the devils, and the villagers can only use rafts or bamboo rafts."

"Besides, even if we get a boat, the experienced boatmen in the nearby villages are all in the north of Tuozi Mountain, where there is a group of cottages, and no one in the village can handle the boat."

"Copycat?"

Zhang Dabiao, who was looking at the map, raised his head: "Bandits? ”

"It's not a mountain bandit, it's the former Jing County militia, but it didn't bully the people"

Su Jigang shook his head: "This group of people refused to take refuge in the Japanese to do the two devils, so they hid in the mountains, there is a deep dense forest over there, there is a cave in it, they hide in a group, they make a living by fishing in the Jingshui River, they also have a few guns, and they usually rob the two devils."

"It is said that the nearby puppet army and devils have cleared up several times, but they can't do anything about this group of people"

"This group of militias is a bit powerful."

Zhang Dabiao nodded approvingly: "There are devils stationed around here, and it is not easy to survive here."

The establishment of a squad anti-Japanese organization in the rear of the devils, the Eighth Route Army has been making this attempt, the military engineering team, the county brigade, the district team, these troops have sprung up, but the devils have a great effort to clear the rear, coupled with the lack of materials and weapons and ammunition, these troops can only barely survive, it is almost impossible to develop and grow, and even one will be uprooted by the devil if he is not careful.

"You work hard today, go and find a way to contact this group of people, there must be their eyeliner in the nearby village"

Zhang Dabiao pondered for a while:

"You can give them a few pistols and bullets, as a greeting gift, and ask them if they can take us across the river, although there are other ways to break through the encirclement of devils, but they are all very risky, and you need to give up the seized medicines"

"In addition, focus on asking those old boatmen, is there a way to drift directly west along the torrent..."

"Heading west along the torrent?"

Su Jigang's eyes widened: "How can this flash flood go west?" It's definitely going east."

The Great River Flows East...

How can there be a river to the west, even if it is a valley waterway, it is impossible!

With a smile, Zhang Dabiao directly spread out the map in his hand, beckoned Su Jigang to come over, pointed to the dense lines on it, and said:

"Didn't you ask me how I could tell if I could walk in this torrent valley?"

"Haha, I saw it from the map"

"Look at this map..."

Zhang Dabiao pointed to the map, the map is very large, and every hill can be seen clearly, and his finger drew a line along the valley:

"From this map, the valley of these mountains is a river valley at all, and the valley washed out by the flood is actually east-west, you see, this valley is obviously narrow in the east direction, and wide in the west direction."

Su Jigang nodded, the torrents were fierce at first, and then became more and more gentle, and the valley that came out of the impact was naturally wider and wider...

"But that's what it looks like."

Su Jigang asked: "The rivers all flow from west to east, even if there are mountain floods, most of them are in this direction, there are differences, and it is only a small tributary."

"Look at this map again"

Zhang Dabiao took out another map, this map is different from other maps, it is full of dense circles of lines, and even the peaks are surrounded by circles of lines.

Drawing the river valley on the map, Zhang Dabiao continued:

"This is a contour map, judging from the contour line, this river valley is obviously high in the west and low in the east, and it spreads all the way to a long distance, and it does not intersect with the Jingshui River..."

Due to the size of the map, the end of the riverbed between the valleys cannot be seen on the map.

"It's really..."

Su Jigang is also an intellectual, proficient in cartography, naturally knows contour maps, and is very good at reading, he can see the river valley from west to east on the map at a glance, and he also sees more things...

His eyes widened suddenly, and his tone exclaimed:

"What a wonderful map, the contour line is actually marked to the decimeter level, and even the seasonal water depth of the river valley is marked"

"There's even a soil mark..."

"And the vegetation species..."

"And the speed of the river..."

Opening the canvas waterproof document bag that Zhang Dabiao was carrying, and looking at the thick stack of maps inside, Su Jigang became more and more excited, and in the end, his eyes almost lit up:

"This mission is really worth it, even if you don't have those 100 tons of weapons and ammunition, just this stack of maps is worth it"

"Absolutely worth it"

Maps, especially such high-precision, multi-data, and multi-information maps, are not much worse than aircraft artillery for the military.

With this kind of map, people who can read maps can almost not need too much on-site investigation to fight, and can directly make a battle plan on the map, and then make a slight adjustment on the spot...

Just this hand, how much time can be saved, and how many fighters can be fought for?

With this kind of map, there will never be a situation where you find that the river is too deep to cross, the soil is soft, the woods are too dense to pass, and the marching speed does not know how much you can increase!

"When the task is completed, I will have two weeks on this map, no, just a week..."

After returning to the group, be sure to make a few more copies of all these maps...

Don't take two weeks, sleep less, and make a copy of it in a week...

And this thing.,The devil's military map or something.,It's garbage.,It's definitely garbage.,Even if it's a legendary aerial photo map.,I'm afraid it's not as good as this...

"Where did this come from?" Su Jigang asked.

He has made maps, and the difficulty of making this kind of map is high, and the amount of data that needs to be investigated is unimaginable...

Accurate to the contour line of the decimeter, the vegetation, soil quality, and even the seasonal water depth and flow of each mountain and forest change, and then expand to a radius of hundreds of miles... That's a lot of work.

Even a professional mapping team of hundreds of people can't do it in a year.

"Haha, there are still a few spare parts on the mule of this thing, I will give you a copy later, remember not to lose it, and the regiment commander still has a few points, which are provided by our employer"

Zhang Dabiao, as a soldier and a battalion commander-level officer, naturally knew the preciousness of this map and the difficulty of making it, so he bared his teeth: "As for how the other party made it, I don't know."

"I guess it was an airplane shot, and then I asked a university professor to draw it."

"Haha, thank you"

Su Jigang smiled with a smile on his face: "I'll leave now"

Calling a soldier, bringing half a box of shell gun bullets, and two shell guns, and then taking the atlas given by Zhang Dabiao, Su Jigang hid in the shadows of the night and walked towards the village in the distance.

······

Separate regiments.

Yang Village.

In the evening.

"Political commissar, the cartridge casings and weapons and ammunition have been loaded" A platoon commander of an independent regiment ran over and saluted Zhao Gang.

"Okay, get ready, bring something to eat, and get ready to go"

Zhao Gang nodded: "This time I am going to the headquarters arsenal, and we must hurry back as soon as possible, let the comrades speed up, we have to rush overnight"

"Yes" the platoon leader ran towards the convoy full of supplies.

"Commissar, here's the list"

After waiting for a while, a soldier ran out of the regimental headquarters with a stack of documents in his hand: "This batch of materials has a total of 370,000 shells, 2,000 rounds of 60 mortar shells, 4 60 mortars, and 2,000 German-made large tumors."

The soldier took a piece of paper from the shabby folder in Japanese and handed it to Zhao Gang.

"Okay"

Zhao Gang took the paper, folded it and stuffed it into the bag on his chest, and then followed the motorcade that had already arrived at the entrance of Yangcun Village on foot.

Before leaving Yang Village, he looked back at the village and squinted his eyes...

Li Yunlong asked him to lead the transport team, and transported the bullet casings to the headquarters arsenal and headquarters, as well as some weapons and ammunition, on the grounds that the officers could not leave the recent training in the regiment...

This is a reasonable reason, he has seen the great progress of the fighters recently, and he can't refuse...

But! It's been nine days, and the commandos haven't returned...

There is definitely something wrong with this Li Yunlong, and he doesn't know what he is planning.

"Departure"

Zhao Gang turned his head expressionlessly and kept up with the transport team: "Speed up and strive to come back the day after tomorrow"

Want to leave me alone?

I will be able to get to the headquarters tomorrow, and then I will be able to borrow a horse and rush back to the Independent Regiment at noon, and I want to see what this guy wants to do.

·····

Under the eaves of a house in Yang Village, Li Yunlong and Kong Jie were watching Zhao Gang leave.

Kong Jie smacked his mouth and took a puff of his pipe:

"How did you kid get him to go now? Didn't you say that this little show just discovered the problem? Is he willing to leave? ”

"Hey, hey, hey..."

Li Yunlong smiled:

"I told this little show to let him leave the morning after tomorrow, but he naturally refused, and he wanted to leave overnight today, which was not busy all afternoon"

"Xiao Xiucai fights with me..."

"Lust and Indulgence"

Kong Jie raised his eyebrows: "Okay, Lao Li, this will be a battle of wisdom"

"Hahaha..."

Li Yunlong laughed, then changed the topic, and his tone was solemn: "You go to organize the troops, we will set off tonight, according to the predetermined plan, the assault company should be almost in Yangquan"

"Good"
