Ten plantations, large and small, are located in the vast wilderness land that is more than ten kilometers deep from the city wall of the gathering place to the northern section of the defense line.

It can be said that the four-section defense line was largely established for the plantations in these wildernesses.

After all, the land area in the agglomeration is limited, and the food produced by the seven plantations in the agglomeration area is simply not enough to meet the consumption of 50,000 or 60,000 people in the agglomeration.

The largest source of food is the plantations that spread across the vast expanse of land between the high walls of the agglomeration and the four major lines of defense.

In fact, the vast majority of the output of the seven plantations in the Gathering is directly supplied to the magnates of the Black Light Castle.

These dozens of plantations outside the agglomeration are responsible for the supply of food for ordinary civilians and soldiers.

The southern sector has the largest number of plantations, followed by the northern sector of the defensive line, and the least in the western and eastern sectors, but even the smallest western sector has six plantations, which is almost the same as the total number of plantations in the cluster.

In addition to guarding the gathering place, the four major lines of defense also shoulder the mission of defending the plantation.

However, each line of defense has a depth of more than ten kilometers, and the southern section of the defense line, which is the strongest of the four major defense lines, is only seven or eight hundred professional soldiers, and it is impossible to completely clear all the threats in this vast area, so there are still incidents of dangerous creatures sneaking in, injuring and even killing people in various plantations.

If I remember correctly, the No. 30 plantation assigned by Qu Dingquan, the director of the No. 5 plantation, was in the security zone under the responsibility of the northern defense line.

Working on plantations outside the city is second only to joining search teams, and it is one of the dangerous industries that the residents of the agglomeration are desperate to get rid of.

The speed of the energy vehicle using gasoline fuel is completely incomparable to that of a horse-drawn carriage, and after more than ten minutes, it came to the main outpost checkpoint of the northern line, where the commander-in-chief of the northern line is located.

After being inspected by the soldiers on duty at the main outpost, the vehicle drove out of a barbed wire fence that symbolized the last boundary between the safe zone and the wilderness, and arrived at the real northern section of the defensive line.

The entire northern section of the defense line is composed of dozens of guard posts, eight or nine guard posts and three major guard checkpoints.

The main outpost checkpoint is the general headquarters of the army on the northern front.

Su Huan didn't see that senior brother on this trip.

Coincidentally, the high-ranking third senior brother happened to lead the team to the wilderness to strangle a dangerous race group that had been attacking the defense line recently.

After a period of greetings, he was sent by his senior brother's chief of staff to the sentry post that had been arranged.

No. 7 sentry post in the northern section.

Each outpost is manned by a five-man tactical team of heavily armed soldiers.

And Su Huan is the sixth member of this sentry group.

The sentry post is not as simple as Su Huan imagined, it is an oval fortification built in the hollowed out of the ground, poured with reinforced concrete, and it looks very solid.

The exposed part of the ground is only more than four meters high, while the underground part is seven or eight meters deep, covering an area of seventy or eighty square meters.

In addition to the underground and surface floors, the spiral staircase from the ground floor to the surface layer is also stepped to build two semi-platforms made of prefabricated cement slabs.

Each half deck has three separate lounges.

Although the whole sentry post sparrow is small and complete, the warehouse, rest room, activity area, watchtower, and observation platform should be equipped, which is more than enough to accommodate one or twenty people, and the space for five or six people to be stationed is naturally quite spacious.

Su Huan's five comrades-in-arms for a period of time in the future looked surprised when they saw the chief of staff personally bring people over, and they were even more shocked when they learned that the new members were actually masters who had come to sharpen their combat experience.

The crowd was very quick to unload Su Huan's pile of incredibly heavy luggage, most of which were the rations of the dragon, snake and lizard for a long time to come.

After some greetings, Su Huan's life at the No. 7 sentry post in the northern section began.

From the mouth of Huang Chengzhu, the commander of the No. 7 sentry post and the leader of this small combat team, Su Huan had a general understanding of the specific situation of the entire northern section of the defense line.

There are a total of 29 sentry posts on the northern section of the defensive line, and the numbers are from the 1st in the northern section to the 29th in the northern section.

Naturally, there is no shortage of outposts in the middle that are destroyed by dangerous species, but the original name will still be used for rebuilding after the war.

The No. 7 sentry post in their northern section was demolished into ruins by a passing terror more than ten years ago, and all the sentry teams stationed at that time were killed.

The current Sentry No. 7 was later rebuilt from the ruins.

And between every few sentry posts, there will be a sentry post that governs several sentry posts.

As a higher-level sentry unit, the ratio of personnel and firepower stationed at the outpost is naturally much stronger than that of the sentry post.

Each outpost was stationed in peacetime with a downsized tactical detachment of twelve or thirteen sentinel members.

It is organized according to the military units of the black light sentry wall.

The most basic combat unit is the five-man tactical team.

On top of this is a tactical detachment of twenty-five.

Half of the tactical detachment was stationed at the outpost, and due to the limited number of troops, an integrated tactical detachment was divided into two, each stationed at a sentry post.

There are eight detachments of this drawdown tactic, representing eight outposts.

The No. 9 outpost in the northern section, because it was close to the outermost part of the northern section of the defensive line, faced the greatest defensive pressure, so it was stationed in a fully staffed tactical detachment of 25 people.

In addition to the sentry post and the sentry post, the left front and right front of the northern section of the defense line, where the fighting is fiercest, there is also a left flank sentry checkpoint and a right flank sentry checkpoint.

and the main outpost where the General Headquarters is located.

The left and right flank levels are each guarded by a 100-man tactical squad.

This is the third level of the military establishment, with a full complement of 100 people.

The main outpost checkpoint has two tactical squads, as well as the commander-in-chief's guards and some logistics troops, with more than 200 people.

This is the ratio of military strength in the entire northern section of the defense line, with six or seven hundred troops stationed on a defense line several kilometers long.

The combined strength of the four major lines of defense accounts for one-third of the total military strength of the black-light gathering place.

And they are all the most experienced and combat-savvy troops in the Black Light Gathering Place.

Of course, the garrison of the defensive line is not static.

The garrison troops of the four major defense lines and the troops in the city shall be rotated once a year.

Several of Su Huan's comrades-in-arms had just changed their guards three months ago.

Among them, the team leader and an elderly soldier are already veterans who have changed guards for several years, and the other three are all recruits who have only been in the army for two years and are performing garrison duties for the first time.

"Brother Huang, is there a high frequency of dangerous species in our place?" After eating the canned beef stewed noodles specially prepared for him by several comrades-in-arms, Su Huan and team leader Huang Chengzhu leaned on the observation platform of the watchtower at the top of the sentry post and chatted in the wind.

Huang Chengzhu has two front teeth, according to himself, he is known as Big Tooth in the Northern Front Army, so Su Huan also calls him that, but Su Huan still politely calls the other party Brother Huang.

"Master Su, we are ......," Huang Chengzhu said with a relaxed expression while picking his teeth.

Before he could finish speaking, he was interrupted by Su Huan: "Brother Huang, just call me by my name when I say it, we are not outsiders, we are comrades-in-arms, don't talk about Lord Su, it sounds weird." ”

"Okay, it's not appropriate to call the name, Master Yu is a big man, then I'll call you Brother Su." Huang Chengzhu hurriedly smiled.

Su Huan looked at Huang Chengzhu and showed a smile with two big teeth, and said speechlessly: "Okay, I call you Brother Huang, you call me Brother Su, we will talk about our own things, let's continue." ”

"Okay, let's go on, let's talk about it, we are here, among the dozens of sentry posts, the entire defense line system is close to the middle and periphery, and the defense pressure is naturally not as great as the outermost sentry posts, but almost every day, there will still be dangerous creatures that break into the outer defense line without knowing whether they are alive or dead."

"Generally, they are second-level dangerous species in the mature stage, but there will still be low-level dangerous species in the mature stage every once in a while."

"If it's just three or five dangerous creatures at the level of secondary danger, relying on the firepower of a few of us and a few guns, and with fortifications to rely on, it will naturally be easy to deal with."

"Even one or two low-level dangerous species are fine."

"When I was just eating, I saw the warehouse opposite the kitchen, which was full of dangerous creatures that we had hunted in the past few days, and every month in the middle and end of the month, there would be an officer who counted military merits and brought a convoy from the city to transport them away, and settled the military merit points for us." Saying that, Huang Chengzhu stretched out his hand and pointed to the warehouse downstairs, revealing a smug look.

Su Huan also gave a thumbs up to show respect.

As an ordinary soldier, it is indeed a matter of pride to be able to hunt so many dangerous creatures every month.

Huang Chengzhu smiled: "But the fortifications are not omnipotent, once there are more than nine secondary dangerous species in the mature stage, and more than three low-level dangerous species, it is usually not something we can solve all, but at this time, we can also try to solve some of them, and notify the sentry post behind them to prepare for battle through wireless telephone, and they must not be allowed to sneak into the safety zone behind the defense line." ”

"Of course, once the number of second-level dangerous species exceeds fifteen, and the number of low-level dangerous species exceeds five, you must notify the subordinate sentry post where you are located and prepare to engage all of them."

"Brother Su, don't worry, by tomorrow night at the latest, you will definitely be able to see dangerous creatures." In the end, Huang Chengzhu packed the ticket.

Su Huan nodded slightly, then closed his eyes and prepared to start his daily spiritual tempering.
