The operation of building fortifications is carried out in the complex passages of the underground world like spider webs, and its function is to reduce the enemy's range of action step by step, and the ultimate goal is to block the enemy, so the white wolf gave this operation a code name, called Operation Web Weaving. ()

In the preparation stage of the operation, the White Wolf recruited a large number of goblins, trained them to learn to make cement, concrete and build walls, after countless failures, the goblins finally through their cooperation, built the first concrete wall of the emirate, although this wall is uneven, it looks like the face of the goblin, it is very ugly, but its sturdiness is still no problem, so even if this group of goblin craftsmen are qualified, after all, the fortification only needs defense, not the appearance of beauty.

White Wolf incorporated these trained goblin workers into the industrial department, and set up a subordinate department of the industrial department for them, called the Ministry of Military Industry, which is responsible for military industrial construction, and in the future, White Wolf plans to continue to expand it.

In the emirate's system of authority, there is actually a construction department at the same level as the industrial department, but the white wolf did not give them the task of building fortifications, because this department is mainly responsible for domestic production and construction, such as digging burrows for ordinary goblins, providing housing, widening and repairing underground passages in the emirate's territory, making transportation more convenient, and so on. The newly established military industrial department is responsible for military production and construction, although the two have overlaps in specific work areas, but they are oriented to different objects and have different functions, so the white wolf distinguishes them, so that it is convenient to manage.

Although the newly recruited goblins have received a lot of training from the White Wolf, when they start their official work, there are still various problems, such as conflicts with the military department on some specific matters, insufficient sand and gravel for logistics supply, unable to make enough cement, etc., but this is only a small problem, the most important concrete manufacturing technology has been lit up, and the rest needs a little adaptation and running-in.

The black wolf is in charge of the military, and she is also one of the general leaders of the "Web Weaving Operation", under the mediation and reconciliation of her and the white wolf, the two independent departments finally began to recognize and accept each other, and when performing the task according to the regulations, the two cooperated quite well.

On the other hand, thanks to the efforts of the construction department, the underground passage to the northern border was repaired ahead of schedule, making transportation more convenient, and at the same time, the agricultural department also provided dozens of Dixing Dragons to assist in transportation, and finally, with the strong cooperation of various departments, the problem of logistical sand and gravel supply was also solved, and these small things are being transported from all over the emirate to the front line through the underground passages and the transportation of Dixinglong.

The water conservancy department has discovered an underground river in the north, and they have dug a canal to the northern border according to the instructions of the white wolf, and the water will be used to supply the army and make cement.

Of course, the most important food supply was not left behind, and these people working on the northern border, whether military or workers, received free three meals a day from the emirate, which, of course, was also part of the emirate's remuneration.

After all these troubles were resolved, the network was finally on track, one fortification after another was built, the passages were cleared by the soldiers, and the area controlled by the emirate was rapidly expanding, which also meant that the territory where the Grey Mist invaders could operate was rapidly shrinking.

While the White Wolf is carrying out a rapid encroachment policy, he is also actively training the army, because he knows that the Gray Mist invaders will definitely attack again, in the last battle, although he suffered heavy losses, but the other side also did not get good fruit to eat, the team of fifty people was all blocked by them and killed in the passage, the White Wolf believed that if the opposite side still had some level of intelligence, it would be impossible to turn a blind eye to this "missing" team, God knows how many people they will send to attack the emirate after this.

The White Wolf was right, after a month of encroachment on the territory, the Grey Mist invaders finally attacked again, and several sentry teams in charge of vigilance brought back the news of the enemy's attack at a heavy cost of casualties.

The Sentinel Unit is responsible for guarding the adjacent junction while the Ministry of Military Industry is building fortifications, and the fortifications that have not yet been repaired cannot be used for defense, once these alert units detect the enemy attacking, they will quickly return to the front line junction along the passage and relay the message to all the troops at the junction.

If the fortifications at the junction have not been repaired, all the men will retreat to the last repaired junction and wait for reinforcements to arrive.

The structure of a general fortification is such that the whole is a concrete wall, and in the center of the wall there is a heavy iron gate that can be opened and closed, and once the iron chain wrapped around the iron gate is loosened, the iron gate will fall, and the iron gate is extremely heavy, and it is so tightly stuck with the hard concrete structure that it is almost impossible for people to push it open.

There are also a few windows on the concrete fortifications for counterattacks, the bottom window is narrow enough for the goblins to stick out their knives and slash the enemy, and there are also firepower vents above the fortifications for automatic miners, with which the clerics can rely on the fortifications to fire at the enemy with impunity.

"Tell me, what should we do?" asked the black wolf as he looked at the map in his hand, which marked the passages, meeting points, the location of the chieftains, and the location of the sentinels.

"We have a total of three sentry stations that have been attacked by the enemy, judging from this, the enemy should have come in three ways, it seems that they have learned wisely, and the other side has reinforcements to respond, I am afraid that we will not be able to surround and annihilate them like last time. The black wolf also looked at the map, analyzing.

Judging by the sentry's news, the number of people on the opposite side is about 150 people, and they are divided into three teams in total, with a total of 50 people in each team, that is to say, the troops invested on the opposite side this time are three times as many as last time, but the position of these three teams of enemy troops is relatively far away, and it can be said that each team is isolated.

"Not necessarily, they are so far away, even if we surround some of the enemy, how will the other teams know that their teammates are surrounded? The white wolf didn't seem to agree with the black wolf's idea and expressed his opposition.

"Don't forget that weird gray fog, maybe there is a way on the other side that we don't know how to convey the message? Maybe the enemy also has heralds, as long as our side moves, the other two groups of enemies will react quickly, there are other possibilities, for example, the sentry only sees the enemy's vanguard, maybe there are more enemies waiting for us behind. The black wolf retorted.

"It's not as much as you say, and I want to warn you, do you think the enemy is really here to attack us?"

"What do you mean by that?"

"You think, it's right that we wiped out the army of the Gray Mist invaders last time, in this case, that army has no chance to convey the news to its base camp, that is to say, for the enemy, this army is not annihilated by us now, but is still in a state of "missing" whereabouts, it can be seen from the strength sent by the enemy, 150 people is obviously too little, if they are really coming at us, it is absolutely impossible to send only such a small number of people. ”

"You mean these three teams are just scout teams, and they most likely have no other support?" asked the black wolf, confused.

"I never said that they did not have support, I just wanted to state the fact that it is quite possible that the enemy is not ready for a full-scale war with our emirate, and they do not yet know our strength. ”

"Well, what should we do according to you?" the black wolf looked convinced by the white wolf.

"Draw the enemy in front of our fortifications, and when all the enemy is in the passage, then we can block them from behind. At the same time, low-level obstacles should be set up at the entrance of the intersection where the troops responsible for cutting off the enemy's rear route are located, and all other junctions adjacent to this intersection should also be set up with blocking troops, and if the enemy arrives to support them in the process of annihilating the enemy, then these blocking forces should be responsible for blocking the enemy and gaining time for the troops responsible for annihilation.

"I remember the phrase you told me, 'Be invincible first, and then wait for the enemy to be victorious,' and you took the initiative to attack and leave the fortifications behind, isn't that tantamount to violating it?" reminded the Black Wolf, even using the famous quote that the White Wolf had taught her.

We must not miss this great opportunity to annihilate the enemy, besides, we have 30,000 soldiers who can fight, and they only have 50 of them, and if they are not even willing to take some risks in the face of such a small opponent, then there is no need to fight. The white wolf waved his hand helplessly.

"The Emirate is yours, you have the final say. The black wolf found that she couldn't convince the white wolf, so she no longer objected, in fact, she had accepted the white wolf's plan in her heart, she thought that the white wolf's analysis made sense, the black wolf had fought with the human powerhouse countless times, and was very aware of the importance of the initiative, and now it should indeed take the initiative to take the initiative and hold the initiative on the battlefield in their own hands, instead of responding passively, cowering and hiding behind the fortifications, so as to miss the precious combat opportunity.
