First, the main resistance forces of the Walled City Alliance have been driven to the Four Waters City by the Eternal Night Legion like ducks, and the forces are unprecedentedly condensed, with at least 30,000 soldiers alone.

Although they are all routed, but the rabbits will kick people when they are in a hurry, if they are forced to be anxious, a bite back, I am afraid that it will hurt very much, although the main battle legion of the Eternal Night Legion is elite, but it can't change the fact that the number is not more than 10,000.

In the eyes of other generals, a small number of casualties in exchange for final victory is a very profitable thing, but in the eyes of the Eternal Night Legion, it is not, unless necessary, they are not willing to sacrifice even one more soldier - attacking the Four Waters City is very unnecessary.

The other party has been surrounded by them, and has become a caged trapped beast, and it is only a matter of time before they eat them.

What's more, they can hold together now because of the powerful external pressure of the Eternal Night Legion here, if the pressure given by the Eternal Night Legion is a little lighter, they will be inextricably contested internally, this is their nature, it has been integrated into their bones, and they can't change it in this life.

Second, Sishui City is a typical water city, less than one-third of it is on land, and the remaining two-thirds are in the lake or on a small island in the lake.

The Legion of the Eternal Night has almost zero experience in water warfare, and if they want to directly attack the Four Waters City, they don't even have the most basic conditions.

Third, the speed of the Eternal Night Legion is too fast, the battle line is too long, even if the size of the attached engineer corps is twice the size of the main corps, but the area occupied is too large, they can't take care of it at all, and some of the attached engineer corps have their own tasks and have no way to rush over, such as the first and second subordinate engineer corps that are building the Twin Cities.

The Walled Cities Alliance's walled cities, not all of them are truly surrendered, they must stabilize their positions as soon as possible, eat them into their stomachs, and digest them, that is called the real occupation.

Once the policies of the Legion of the Eternal Night are instilled in them, and when the Walled City Alliance comes back and wants to rule these people again, it will be extremely difficult, though the chances of this being are slim.

Fourth, and most fundamentally, and most importantly, an order came from the top of the Eternal Night Legion to suspend the attack and deploy their defenses on the spot.

At the same time as the Hundred Guards of the Eternal Night Legion rushed wildly, Sean, who set up an ambush for the elite success of the Walled City Alliance, was not idle, but followed the underground cave when the Walled City Alliance came, and entered the hinterland of the Three Caves Alliance.

Ben Hebrew is a little too underestimating the Eternal Night Legion, the medical research base, as the core unit of the Eternal Night Legion, is eager to defend to the extreme, how can it leave its own hinterland open?

As early as the beginning of its establishment, the situation of the medical research base within a radius of hundreds of kilometers has been carpet-checked by the Eternal Night Legion, and Mr. Ferdinand, the imperial architect of the Eternal Night Legion, has established a set of quite advanced land and air three-dimensional defense mechanisms, and the number of people stationed here and the fortifications are far more than what has been exposed.

The five walled forts are only a small part of this defensive system.

The underground cavern through which the Walled City Alliance passed was not an absolute secret, and the Legionnaires of the Eternal Night had not neglected their duties to turn a blind eye to it.

The choice to keep it was not for the sake of the Pit City Alliance, but as a retreat for the medical research base.

The Walled City Alliance's long-range attack, which they thought was top secret, would have been exposed long ago the moment they entered the underground cave, even if it wasn't deliberately arranged by Sean.

If it weren't for the Eternal Night Legion's other corresponding arrangements, it would only be a matter of minutes to bury them in the belly of the mountain.

"The Three Caves are known as the most beautiful places in the Andes Mountains, and they live up to their name. ”

Even a big man like McGee, the skull crusher, was attracted by the unique natural beauty of heaven and earth in the Three Cave Alliance, and sighed heartily.

"It's also a natural defensive point. Sean sighed with a somewhat gloomy expression.

Although their number is small, like the previous Walled City Alliance, most of the elite of the Eternal Night Legion have been gathered, and there are two champion knights in charge, which can be described as unstoppable.

But their purpose of this battle, to arrest the lord of the Three Caves Alliance, Ban Hebrew, has been fruitless, they are always one step late, and when they get the information to arrive, Ban Hebrew is like a rabbit, and he has long not known which cave he has slipped to.

The terrain of the three caves is too complicated, there is no Jedi at all, and if you want to block a mastery-level warlock, the difficulty is not half a star.

Fortunately, Ben Hebrew is not alone, and there is no way to leave three holes and fly away, giving Sean a chance to pull his tail.

"It's not okay to go on like this, go back first, guard the entrance of the secret passage, Arnold, release the mountain eagle, inform Marshall to shrink the offensive, mobilize the third corps and the corresponding subsidiary engineer corps to come over, let's occupy inch by inch, and when all the land in the three caves is occupied, see where he is still going?"

After seeing the unique geography of the Three Caves, Sean changed his mind and made this the primary target of the Eternal Night Legion.

Not only because of the beautiful environment, but also because of its unique geographical advantages, at least for the Legion of the Eternal Night.

The east side of the three caves is the place of sunset, the second half of the main vein of the roof of the world, Sanset Peak, which is not under the main vein and faces the danger of a large avalanche at any time, but it is an absolute natural barrier, and the orcs on the Odin grassland are absolutely impossible to cross this place on a large scale to invade, and the river water of the melting snow of Sanset Peak is continuous all year round, nourishing here.

The underground karst cave in the southwest directly connects it with the medical research base, and if the last defensive shortcoming of the medical research base is filled, it will be completely erased from the eyes of the world.

In the northwest, it is connected with the Andes inland lake, with extremely convenient water transportation, although there are hundreds of miles between the two sides, but down the river, only a day's journey, which is rare in the Andes mountains.

Once occupying this place, the Eternal Night Legion will form an encirclement and oppression of Sishui City from two directions: the Sandong River and the ancient channel of the Jacob River.

The only flaw is that before taking the Four Waters City and completely eradicating the Walled City Alliance, the connection between the Three Caves and the Jacob Ancient River is not close.

The first line of heaven connected to the ancient river of Jacob in the northwest of the medical research base is easy to defend and difficult to attack, but it also means that it is rugged and difficult to travel, and the Eternal Night Legion first goes to the medical research base to transport supplies, which is time-consuming and laborious, but fortunately, the medical research base is large enough to complete part of self-sufficiency.

However, Sean, who has a bigger plan in his heart, sees farther, once they blow up the ancient river of Jacob, let the Jacob River return to its old view, and defeat the Four Waters City, the whole game of chess will come alive.

In other words, Sean has taken a fancy to the land of the Three Caves Alliance and is ready to take it down as the headquarters of the Legion of the Eternal Night.

The Flying Eagle Transmission System, which the Eternal Night Legion spent a lot of energy and a lot of money to build, was vividly displayed in this counterattack against the Walled City Alliance.

If there is no such system, this kind of full-line combat with 100 guards as a unit would be death.

With it, it has become the most classic example.

The cooperation between regiments and regiments, schools and schools, and guards and guards, even across several mountains and even hundreds of miles, is still intimate and synchronized.

For this alone, the Walled City Alliance was not unjustly defeated, even if their high-level leaders were not killed by Sean, they could not resist in the face of this advanced tactic that was several grades ahead of the world, at most it would make the Eternal Night Legion advance more slowly and suffer greater losses, which would not affect the final result at all.

When the 1st, 2nd, and Special Purpose Corps of the Eastern Front were shrinking their defensive lines, the 3rd Corps of the Eternal Night Corps led their subsidiary engineer corps, over the mountains and mountains, and directly killed the Sandong Alliance.

However, they did not take a line of heaven and medical research bases, and this place was not suitable for large marches.

Not only here, but in addition to the Jacob Ancient River Road, the entire Andes Mountains are not suitable for large-scale marches, and the Jacob Ancient River Road can accommodate large-scale marches, which is still a matter after the large-scale construction of the Eternal Night Army.

The Legion of the Eternal Night launched an attack on the Walled City Alliance, why did it take the Hundred Guards as a unit?

This is not only due to the need for the Legion of the Eternal Night to work together on multiple fronts, but also because of the unique terrain of the Andes.

The complex terrain determines that the unit of 100 people can not only ensure the most basic combat effectiveness of the siege, but also the fastest speed.

On the contrary, the greater the number of people, the slower the speed of action, and the purpose of running is completely unattainable.

The Third Corps plus the attached Engineer Corps, there are no less than eight or nine thousand, plus grain, grass and livestock, if you use the collective marching mode to reach Sean's designated position, at least a week later, this is still a situation of hurrying and hurrying.

Therefore, the method adopted by the Third Corps was generally the same as that of the offensive on the Eastern Front, with the 100-man guard as the unit, advancing in unison, with the main battle corps as the front and the attached engineer corps as the pole.

The main battle corps went into battle lightly, advanced rapidly, broke villages when encountering villages, attacked villages at every time, and did not stop for a moment.

The attached engineer corps that followed behind them fought steadily, building bridges when encountering water, opening roads in forests, collecting villages and villages, and setting up camps and villages.

The former brings destruction and death, and the latter brings rebirth and hope, and the two complement each other and complement each other.

Wherever the Third Corps passed, all the walled cities along the route were directly brought under the rule of the Eternal Night Legion.

However, the disadvantage of this is that the demand for the number of affiliated engineer corps is a bit large, and the fourth subordinate engineer corps, which is under construction in the Twin Cities, has to be transferred.

The defensive line of the 4th Main Battle Corps moved forward and was stationed on the ruins of the Bastille.

Although the Eternal Night Legion has not established a second legion in the past two years, it does not mean that it has not developed itself, and it is now a typical strengthened legion.

Not only the Fourth Main Battle Corps was established, but all the corps belonged to the Reinforced Regiment and Reinforced Colonel, but there was not much change below the guard level.

A small corps has added one reinforced colonel, and many have even added two or three reinforced colonels, and a corps is almost independent into an army.

When this war is over, the Legion of the Eternal Night will be divided into two and a second legion will be formed, which will be a matter of course.

Although the Third Corps was temporarily ordered, the speed of its furious advance was only faster than that of the Eastern Front.

Although the Eternal Night Legion did not occupy the mountains on both sides of the ancient river of Jacob, under the encroachment of its alliance with the walled city, the young and strong mountain people in the mountains on both sides moved to the ancient river channel of Jacob with their families, villages, and villages.

Those who remain here are either those lonely old people who are unable or unwilling to move, or they are extremely remote and insecure small mountain villages and small towns, most of which are family-based.

Most of them are empty villages, and even some soldiers have moved out from here, and they know the surrounding situation well, and they will lead the way without much effort.

Many hundred guards came down all the way, basically did not move a knife or an arrow, until they entered the inherent territory of the Three Caves Alliance, the two sides drew their swords against each other, and the fight was quite difficult, because the resistance of the Three Caves Alliance was quite resolute, not only the ruling class, but also those mountain people of the Three Caves League below.

Because for them, the Legion of the Eternal Night is an out-and-out invader.

In the eyes of the Legion of the Night, the Walled City Alliance is a joke in the truest sense of the word, not only for their usual level of management, but also for the way they are formed in the same way they joke.

But it doesn't mean that there is no cohesion within the Walled City Alliance, as the cohesion of the old forces, the Three Caves Alliance and the Four Waters City are beyond imagination, especially the Three Caves Alliance.

With their unique geographical advantages, they have always been a pure land in the Andes Mountains, and Ben Hebrew can be regarded as a qualified ruler, and his political skills are quite powerful - if they are not powerful, it is impossible to integrate the three caves together and become the master of the three caves.

Over the years, the Sandong League has been a model of invincibility and aggression externally, and brutal oppression, and over time, it has naturally developed a feeling that the people of the Sandong League are superior, and on the contrary, it is a super centripetal force and cohesion.

Super cohesion and centripetal force can create miracles at some times, but in the face of absolute strength, there is no way to change the final result.

The strong walled city and the morale of all the people can indeed withstand the edge of the hundred guards of the Eternal Night Legion.

But when several centenarians were connected in series to form a military academy, and the follow-up attached engineer corps followed, and catapults and self-propelled crossbow carts were erected, their defenses were so vulnerable.

Under the indiscriminate bombardment of a large number of siege equipment, even the extremely strong masonry city is difficult to resist, not to mention the walled city dominated by civil structures, in the end, the only thing they can rely on is their own natural risk.

For this kind of walled city, the Legion of the Eternal Night also has its own methods.

It's not that you have to fill it with your life, and you have to take it down.

If anyone uses such brainless tactics, they will definitely be used as a negative teaching material and criticized by name at the next officer meeting.

Depending on the size of the walled city, they threw different numbers of subordinate engineer regiments there, built defensive camps, and blocked them in the walled city, and it didn't take long for the attack and defense to change hands, or surrender without a fight.

Because of the natural danger of the city, most of them mean that the roads are relatively unique, and they are rugged and difficult to navigate, once the water source is cut off, it is easy to become a Jedi, and then the situation will be fundamentally reversed.

If you want to attack the military camp of the Engineer Corps attached to the Eternal Night Legion, the price you need to pay is not ordinary, and even if you defeat it, you usually get a ruin, and then desperately find that the other party has set up another defensive camp not far away.

No one knows whether the other side will build another defensive camp after this camp is captured.
