The enemy's reinforcements, which existed only in the possibility, did not appear, and indeed as the white wolf expected, these enemies were now in a state of solitude, and they were soon surrounded by the black wolf's army, with strong fortifications in front and rows and rows of shield soldiers in the back.

Just like last time, the shield troops at the front quickly exchanged fire with the enemy, unlike last time, the optimized shield soldiers can defend against the enemy's impact very well, the white wolf learned the previous lesson, and deliberately set the center of gravity of the armor slightly tilted forward, so that the shield soldiers are bound to be in a state of leaning forward for a long time, plus they have all received impact resistance training, for the shield soldiers, this time to resist the attack from the gray fog invaders is not as difficult as before.

The way the invaders fought did not change, they still rushed forward frantically and then slashed brainlessly, which gave the emirate's army an opportunity, and the training platoon carried out by the black wolf specifically for these invaders came in handy, and some of the most basic formation changes made these enemies unable to break through even the first line of defense.

The specific operation process of the formation change is as follows: whenever a goblin shield player is overwhelmed and is about to be unable to resist the attack from the opposite side, the automatic miner will attack, strike at the enemy at the front of the line, and when the enemy is knocked down by the shock wave, the shield player in the second column will take turns to the first column.

In fact, the interval of this rotation is determined by the automatic miner, which fires a thunderstorm every 15 seconds, and when the thunderstorm has been carried out four times, i.e. after the first row of shields has resisted for 1 minute, this rotation will take place.

Although the shockwave of the thunderstorm does not deal much damage, its coverage is large, and a single attack can basically inflict a hard stun on all enemies at the front of the enemy, and by the time the enemy comes to his senses, the rotation of the shield array has already been completed.

And there is more than one automatic mining machine, and the shock wave generated when multiple thunderstorms explode at the same time is terrifying, and sometimes even the shield hand can't resist it.

Each shield array has a column leader, and when the rotation is about to take place, this column leader will shout, and then the rotation will begin.

Since there is still a layer of axe hands between the two columns of shield bearers, when rotating, if this column of axe bearers does not want to be an obstacle, they can only retreat to the rear with the first column of shield bearers, after the shield bearer column leader shouts, the axe hand and the shield hand will turn to the left side at the same time, and the next two columns of soldiers will go to the right side, and then the left team will retreat, and the right team will advance, and wait until the two are in place, and a formation rotation will be completed.

The two columns of soldiers who retreated to the back would continue to retreat, while the soldiers behind would take their place and move to the front, and they could retreat all the way to the back of the five columns, where they would get a five-minute break. The reason why they are no longer allowed to continue backwards in order to get a fuller rest is that if they retreat too much, the morale of the soldiers will drop very quickly, and the mood of stealing will be generated, so this rotation can only be stopped.

The rotation tactics have been repeatedly practiced, discussed, summarized, and modified by the white wolf and the black wolf, although there are still many imperfections, but they can finally be used in combat. Its effect on the battle against the Grey Mist Invaders is very good, the soldiers at the forefront of the front line always maintain their full physical strength, and the sword and axe hands behind them can do their best, reassuring and bold to inflict damage, they have been fighting fiercely for three or four minutes, the situation of the Grey Mist Invaders can only be described as heavy losses, and they have not even been able to break through the first array of the Emirate.

"Such a foolish scoundrel can probably only be used against these brainless intruders," the black wolf stood behind the fortifications, observing the entire battlefield, and had to say that she was quite happy when she saw her soldiers achieve such great results.

It's just that she knows that this kind of tactics can only be applied to the underground passages of the underground world, and can only be used to deal with the gray fog invaders, if the battlefield is set in an open area on the ground, the thunderstorm of the automatic mining machine is limited, and it will definitely not be able to take care of the enemy coming from all directions, if it is rotated at this time, the front line is easy to be scattered.

On the other hand, if the enemy has a little intelligence, and doesn't know how to rush silly like the Grey Mist Goblin, and knows how to use a shield to defend against thunderstorms, or knows how to damage the shieldholder's weak skins that are not protected by armor, these shieldholders will certainly not be so useful.

However, one yard to one yard, in any case, the tactics applied by the emirate are still quite effective, the enemy is simply unable to break through their defenses, and the shield and axe men rotate round after round, and even push the confrontation line forward by some distance, compressing the enemy's range of movement into an extremely limited space.

The battle on the fortification side has not stopped, many of the garrison soldiers' knives have been curled, but this is not a problem, the black wolf has prepared a lot of brand-new weapons for them in advance, if you feel that the chopping is a little unsmooth, these soldiers can be replaced at any time, some knives are thrown away before they are fully used, but she is not distressed, there are enough weapons for them to use, after the battle, these weapons will also be collected uniformly and sent back to the steel factory.

If the wear is a little lighter, it can be reused after grinding, and if the wear is very severe, it will have to be rebuilt, but this is not difficult for a steel mill with rune machines.

"Fortify your defenses!" shouted the goblin captain who commanded the siege team, and he saw that the gray mist was shrinking rapidly, proving that the enemy had been cornered and was about to deliver the final blow.

Sure enough, after the gray mist cleared, two porcupine spearmen appeared in everyone's sight, holding blood-red spears in their hands, staring at the Emirate soldiers in front of them with fierce eyes.

The shieldbearers fought with all their might, holding up the heavy shields to cover their teammates behind them.

Just before the two porcupines were about to throw their spears, several thunderstorms whistled and slashed, this attack obviously worked, the porcupine people standing in front of them under the influence of the thunderstorm, the direction of the spear was a little off, failed to shoot into the military formation of the emirate, and directly inserted it into the ceiling.

However, the second porcupine man was unaffected, its spear had already flown at a terrifying speed, and the shieldbearers had to take it hard.

The kinetic energy contained in the spears of the porcupine people was extremely great, although the shieldmen tried their best, they were still unable to resist, just like the first battle, several spearmen were shocked to death, and the front of the emirate was also torn open, the remnants of the gray fog goblins and porcupine people, one after another, poured into the gap in the line, began to kill, they no longer attacked the fortifications, but went all out to attack the troops besieging them, especially the two porcupine people, they rushed to the front, as if they wanted to break through.

Seeing this scene, the black wolf couldn't help grinding his teeth, the long-range attacks of these porcupine spearmen were too strong, and if they came a few more times, the army of the emirate would definitely not be able to hold it. She was a little angry, why couldn't the soldiers she had worked so hard to train couldn't withstand a spear thrown by these guys?

The Porcupine Guys' breakthrough plan failed, in fact, when they threw that spear, the battle had already come to an end, except for the Porcupine who could also use brute force to overturn the shield man's array, the rest of the Grey Mist Invaders were no longer able to launch an effective attack on the Emirate's array, because the gap in the array caused by the spear was quickly filled by the reinforcements behind, and under the triple disadvantage of numbers, equipment, and tactics, the Grey Mist Invaders lost after all.

As the last enemy was beheaded and the body fell to the ground, the black wolf exhaled, the battle finally ended with the victory of the emirate, the whole battle lasted less than ten minutes, all the enemies were annihilated, except for the last spear throwing made her feel a little angry, the rest of the time the battle was hearty.

"Let the troops on the opposite side of the fortifications immediately withdraw from the battlefield, leaving only a small number of people to clean up the battlefield, and the troops who have just participated in the battle return to the base camp to rest, and the rest of the people will immediately go to the No. 11 fortification, where we will fight a second battle!" The black wolf explained his order to her herald, since he had annihilated one of the enemy's troops at a very small cost, it was time to take the opportunity to expand the results of the battle and destroy the remaining two forces of the Grey Mist invaders.

When the White Wolf received the report from the Black Wolf, it was already the next morning, and in her report, the troops of the Emirate successfully used the decoy tactic to surround three small groups of enemy troops, and only paid the price of 34 killed, 20 seriously wounded, and a few lightly wounded, and annihilated 150 of the enemy, although the scale of the battle was not large, but it was still a perfect victory.

"Very good, very good, it seems that you can rest assured for the time being. The white wolf closed the report with satisfaction, and at the end of the report, the black wolf emphasized the enemy's spear throwing, almost every casualty was caused by such a spear throw, and the black wolf wanted the white wolf to think of a way to see if there was any way to restrain this spear throw.

However, the white wolf has no good way to refrain from throwing spears, unless he kills the porcupines before they throw their spears, or carries enough armor to defend against spears, neither of which the white wolf can do.

However, the white wolf didn't think that there was anything to worry about in this kind of thing, how could it be that there were no casualties on his side at all? From the enemy's point of view, if they couldn't inflict the slightest damage on their side, then what else could they fight, it was better to surrender directly.
