Yanchang is located in the west of northern Shaanxi, the terrain here is not the kind of loess high slope in Shaanxi, but the mountains overlap, the mountains are ten thousand ravines, the mountains are also the kind of high pinnacle mountains, the extension of this side is hundreds of miles around this kind of terrain, there is no plain flat open place at all.

Only on both sides of the river, the river plain formed by the impact of the river, even if it is a river plain, the flat area that is impacted by this side is very small.

Yanchang County is located on the plain next to the river where the water is bursting out.

This plain is very inconspicuous in high-altitude maps, and looks like a ditch in the mountains.

Li Chu originally wanted to descend near Yanchang County, but the situation nearby made it difficult for him.

In the vicinity of Yanchang County, in addition to the county seat of Yanchang County, the nearest small plain that can accommodate the landing of airships is downstream of the irrigation water, and the nearest one is at the turn of the four-kilometer river, because of the rotation of the earth, the river moves on the other side when the river turns, resulting in an alluvial fan plain in the shallow water area.

But this alluvial fan plain is a slope with a relatively low soles, and it is okay to barely stop.

And there is a huge problem that there is no way to the county seat.

Yanchang County is in the west of Yan'an, is the western boundary of Yan'an Province, is also the western boundary of Yongxing Military Road, with the Yellow River as the boundary, Yanchang County to the west is the Yellow River, the irrigation water in front of the door is injected into the Yellow River, the road is only broken to Yanchang County, west of the county seat of Yanchang County, there is no big road, it is a small road, people can walk, if it is a tank and a car, and the transportation of oil is a big problem.

And you can't take the waterway.

I don't know why, after the Qingshui River passes through Yan'an, the water in this river is scarce, and boats can only be sailed during the flood season, and the water level on the river on weekdays cannot support boats at all.

I only think about oil extraction, but I don't think about the terrain here.

Fortunately, there were satellite topographic maps, and finally Li Chu found an open area for landing on the top of a large mountain in the upper reaches of Yanchang County.

Yes, at the top of the mountain, on the top of a mountain range to the north of the grout water, here is a flat floor for the landing of the Exocet.

Not only that, but although there are alpine ravines on this side, many of the mountains here are bare meadows, and there are no huge potholes and cracks all the way down, so it looks like a high mountain slope.

In this way, both tanks and cars can drive directly down this slope without the need for roads, and the terrain of the slope is also inclined and flat.

It is a little far away from Nayanchang County, nearly seven miles away.

After the landing site was chosen, the action on the part of the system also began.

The task of oil exploitation is the nature of cooperation between the two parties, Li Chu provides equipment and equipment, and customized systems provide operation and construction personnel. After the airship flew into the area of Yanchang County, the construction operators provided by the system had also done a good job of cleaning up the landing area, removing some nearby things that were not conducive to landing.

And a prefabricated house was built here.

On the ground, there are also heading lights to guide the landing of the airship.

The soldiers in the airship had also rested, and at this moment, under the supervision of the captains of each team, they checked their clothes and weapons and equipment, and prepared for battle.

Li Xuan also gave the goal of this mission to each soldier.

The 300 rapid reaction force and the four teams of the Navy, together with tanks and automobiles, were mixed into the first team, which was responsible for raiding and capturing the county seat of Yanchang County and controlling the county seat.

The remaining six teams of soldiers were responsible for capturing oil extraction sites, cooperating with the engineers in the construction of the wall, and doing various safety protection work.

At night, everything is quiet.

No one noticed that a huge creature had fallen in the sky, and the navigation and other things below the airship had been turned off, and they quietly landed in the chosen position.

This mountain top has no name, and Li Chu temporarily named him Feiyu Gaopo as a base in the future.

After the airship landed, the engineers and architects inside were already ready.

As soon as the hatch opened, the soldiers quickly ran out of the hatch in a queue, and quickly assembled in the open space on the side, and finally the liberation cars and tanks drove out of it.

The tank has now been handed over to Li Qun to drive, and Li Chu is in the commander's position, and the seat is raised to expose most of his body on the turret.

Torches, not needed.

Each soldier on this mission was equipped with a special helmet, which was not a special helmet, the kind of helmet of later generations, and a flashlight was installed on it.

After the Leopard 1 tank came out, everyone's attention was on Li Chu.

Li Chu waved his hand, and the team leader at the front immediately shouted, leading the team forward.

The rapid reaction force has three hundred people, and three cars are clearly not enough to ride.

Three cars drove at the front of the road.

Li Hezuo was in the car, holding a map of Yanchang County in his hand, which marked the route down the mountain and the route to capture the county seat.

Li Xuanze finally jumped on the Leopard 1 tank, climbed onto the turret, sat on the turret, and took a ride.

A map was spread out on the turret, and Li Chu gave Li Xuan a flashlight to fight, and studied with him how to quickly capture the county seat.

This map is the same as the one Li He saw.

In addition to the route down the mountain, the most critical thing is satellite aerial photography.

The location structure of the houses in the entire county was all photographed by satellites.

The location of the county office is easy to find, with several distinctive features, plus the shooting effect on the map is also clear, even people walking around can see the color of his clothes.

Li Xuan didn't have time to sigh how Li Chu got this detailed topographic map, he listened carefully to Li Chu's strategic plan, and digested it in his heart.

The construction team and mining technicians from the system followed at the back of the team.

This generation has very few residents living here because of the poor mountains and bad waters, and now it is midnight, and none of the residents notice the difference here.

Yanchang county seat.

Because of the topography here, the role of Yanchang County is very small.

Since the opening of the Great Song Dynasty, there has not been a major war.

Even if it's a bandit or robber......

Yes, there are many cottages hidden in this big mountain, but none of the thieves are willing to come to Yanchang County.

The reason is that this county is poorer than their cottages, and there are only some poor people who walk on weekdays, and a strong meal is not enough for people to walk and eat, so the ghosts go to rob them. It's just that the terrain here is very favorable for them to hide, so the stockade was built here.

Usually, they all go to the west and grab Yan'an.

The soldiers stationed in Yanchang County have become the most vacant positions in the county, and they don't even have to stand guard, just sleep at home.

As for the safety of the county?

Except for some people who steal chickens and dogs, where even robbers and thieves don't want to come, what else will be safe and terrible?

As for the affairs of the city, only those county governors and officials were to deal with them.

Now that it's winter, it's strange to sleep on the city wall, and that person is willing to suffer this sin?

Therefore, the walls of this Yanchang County were dark and deserted, and there was not even a single torch to illuminate the light...... (To be continued.) )
