Taking history as a mirror, we can learn about the rise and fall, and many of the social problems facing mankind now and their answers can be found in history.

Humans are a race that is good at repeating, but never learns lessons, but this is not entirely a bad thing, when a question is answered a thousand times, future generations will always be able to find the most suitable one for themselves from all the answers.

Throughout the long history of mankind, there are not many wars in which the weak defeat the strong and turn the tables against the wind, and Batman can only think of that war when it comes to the largest gap, the largest scale, the longest time, and the most miraculous.

Batman is more proficient in small-scale tactics, and his personal preference is not for large-scale combat, but that doesn't mean he hasn't studied it.

For a victim paranoia, he is ready for an alien invasion of Earth at any time, and he must be prepared to resist.

Under this assumption, Batman will think about things very extremely, for example, the physical fitness of aliens is much stronger than that of humans, the technology is more developed, more organized and disciplined, and the gap in all aspects is beyond the times.

And if you want to think about how this kind of battle can be won, Batman, who has not personally experienced the war, has to turn over the history of mankind.

And turning over and over, there is only one battle that can meet such extreme conditions, so Batman also focuses on this war.

And the more he studied, the more he found that, in fact, the larger the scale of the war, the less important the external factors were, and in the end they would still be attributed to the three classic conditions, time, place, and people.

The reason why Batman feels that he can win this battle is because his current conditions just meet some of the conditions of the war he studied, that is, when the time and people are not very occupied, the geographical factor is the magic weapon for success.

The so-called time of day, that is, the timing of the war, is indeed not a very good time for the Central Mine, the elite troops of General Rotten Heart are staying on the edge of the Seven Mountains Mine, he himself is in good condition, and there is no shortage of senior managers.

The timing of the move was too urgent, and the pre-war preparations were not made, and the opponent's reaction was relatively fast, and there was basically no big mistake in decision-making.

Not to mention the people, the army composed of these miners and slaves cannot be said to be terrifying, but can only be said to be breathless, and it is a bit difficult to build fortifications.

In terms of education, the vast majority of these demons are not able to transmit orders well, and as long as an order passes through the mouths of three demons, it will be unrecognizable.

Batman tries to use the materials in the mine to rub large traps and machines by hand, but the problem is that these things need to be controlled, and there are few demons that can do exactly what Batman says.

The time and people are basically rotten, so the only breakthrough is just like the war he refers to, which is the geographical advantage.

Judging from the number of people on the opposite side and the number of people on their own side, the entire central mine is already a large enough strategic field that the strategy of exchanging space for time can be implemented.

Moreover, Batman felt that the strategic space he had was even larger than the war he was referring to, after all, the demons didn't need so many survival materials, and they didn't have to think about logistics when they moved. ….

And the location is in a mine, there are not so many strategically valuable locations here, and the more evenly important the location, the less you have to think about when it comes to tactical arrangements.

If the difficulty of a large-scale war with a country as a unit is about high calculus, then the difficulty of a war with a mine unit is almost double-digit addition and subtraction, the basis and principle are similar, but the difficulty is very different, it is all hellish difficulty, and it is also divided into novices and veterans.

At the same time, all the miners and slaves who are still in the mine can be said to know every speck of dust about the mine where they work every day.

After a day's statistics, there are more than 60 large mine caves, more than 30 abandoned mine caves, and many small and medium-sized mountain cavities formed due to natural causes, totaling more than 100, most of which are connected by narrow stairs or corridors.

The terrain is very complex.

This mine was developed more than 1,000 years ago, and General Rotten Heart has only taken over the mine for more than 300 years, and according to the native race in the mine, General Corruptheart's elite troops will not enter here at all, they hate this group of stinky slaves, and they haven't even come in to see it.

Those complicated passages, sometimes, even the old miners will get lost, even if they take a minecart, they don't know where to turn, which achieves one of the most important conditions in Batman's strategy, that is, the enemy does not know me.

Of course, the internal structure of the mine is an afterthought, and the first thing they need to do is to defend the vanguard of the attack on the outside of the mine.

The central mine as a whole is spindle-shaped, high in the north and low in the south, and the highest point is located at the top of the big mountain peak in the north, and the two big peaks each have two gates and two small gates, all of which are blocked.

Between the large peaks on the north side and the large peaks on the south side, there is a ravine through which the minecart tunnel is not blocked.

Batman's main tactic is that since he is defending the mountain, he must give full play to the advantages of high and low, and new caves have been dug above the gate and small gate to attack the troops who rush the door, and the minecart tunnel in the ravine is also deliberately not blocked, once the main gate attack is frustrated, they will inevitably hit the idea of the tunnel.

The tunnel is located between two mountains, and there are slopes on the left and right sides, that is, as long as they dare to pass through the tunnel, they must be at the lowest point of the mountain, and at this time, standing on every point of the hillside, there is an advantage of high and low.

Because the physique of the demon miner slave is generally weaker than the demon soldier on the opposite side, and the number is smaller, and it can't withstand consumption, so Batman simply doesn't fight at all, and the most important thing in the mine is heavy rocks and sharp ores, the first wave of attacks, how many are thrown.

Although the demons of the vanguard are strong, not everyone can armor and magic, and their heavy armor can withstand the stabbing of spears or the swing of broadswords, but they cannot stop the boulders rolling down from hundreds of meters in the air.

It turns out that as long as there is gravity, throwing stones is an all-purpose tactic, as long as it is high enough, it will definitely be able to give the opponent a head-on blow, and under gravity, everything is equal. ….

Batman stood at the top of the big mountain peak on the north side, directing the demons to throw huge rocks from the top of the mountain, one after another, the central mine is called the big mine because the mountain is very large, the mountain is very high, so the stones have enough time to store energy.

Countless boulders tumbled down from the top of the mountain, and rows after rows of strong demonic heavy armor soldiers charged towards the gate with their weapons held high, and by the time they saw the falling rocks, it was too late.

The size of their equipment and the weight of their equipment did not allow them to disperse and turn back as quickly as light armor soldiers, and most of the demons were knocked down by the stones, although they did not die, but this wave of charges was considered a failure.

In the second wave of the charge, they wanted to take the flank encirclement, divide into several teams, and rush to the gate from the side slope, but as long as there are enough stones, there will always be unlucky people who will be smashed down, and even if they rush to the gate, they have to find a way to break the door, and when they stand at the door, they will still be hit by the boulders.

The commander of the other side is not good at stubble, the two waves of charges failed, and they quickly responded, many flying insects flew up from the cantonment field, Batman squinted his eyes and looked closely, and found that the insects were hanging on the foot hooks of something like a bomb, it seemed that this was the enemy bomber.

It's true that during the bombing, the miner slaves can't come out and push the stones, and Batman doesn't have a flying card to play, but that doesn't mean he can't use jamming tactics.

In addition to the lack of stone and wood in the mine, there is a large number of logs used to support the structure, and Batman has long asked the demon miners to cut the logs and stack them in the designated places.

When the insect bomber was approaching the peak, he suddenly saw smoke coming out of the opposite mountain, and soon the whole mountain seemed to be on fire, and the smoke was filled, like a fairyland.

Batman is crooked, the weakness of this insect bomber is smoke, which is why Astro's flying thorn army can make him proud,

The Spike Demon is the only one of all the Flying Soldiers in Hell who is not afraid of smoke and dust.

However, even if the insect bombers are not afraid of smoke, it is useless, because of the long-term stability, the intensity of large-scale wars in Hell is not high, and many wars are basically at the level of charging each other in the Middle Ages, except for the assistance of magic.

And because the demons of hell are physically strong and don't need so much assistance, they don't have weapons and vehicles like humans, because they are weak.

The positioning of the insect bomber mainly depends on the eyes, there is no thermal imaging, no infrared induction, no radar scanning, no command positioning, smoke and dust, nothing can be seen clearly, and naturally it can only be drawn with fate.

Many insect bombers have also figured out a solution, which is to keep the altitude as low as possible, as long as they are close enough, they can see clearly, but as long as they are close enough to the ground, the demon miner's weapon can also be thrown on their heads.

The troll's upper body strength is developed, it is the best spear thrower, the insect bomber can't wear heavy armor, as long as it is rubbed to the edge, it will crash, the vision is not good, there is no way to see the opposite movement in advance, the air charge is just ten minutes, two-thirds of the insect bombers have lost their tactical role. ….

After that, just like in turn-based combat, the opposing commander tries to break through the gate by all means, and Batman uses his tactical mind to devise a variety of ways to crack the attack, making the most of the resources in the mine.

Finding that it was difficult to break through the main entrance, they moved to the side door, and when they found that the side door was also arranged, they hit the idea on the minecart tunnel between the ravines.

And just as Batman expected, here, the advantage of geography has been exerted to the extreme, not only high and low, but also double-sided attack, the first half and the second half have plenty of side-firing firepower, and they finally caused the opponent's actual attrition for the first time.

On the one hand, without the cooperation of the air force, it is very difficult to fight low and high, and the attrition of personnel will be much more than that of the defender.

On the other hand, when there is no shortage of resources in the city, it is normal for the ancient siege war to be fought for a year or two, and the defenders are not in a hurry, as long as the city is in hand, that is their advantage, but the siege side is in a hurry, because it cannot be attacked for a long time, which may slow down the offensive rhythm of their all-out war.

Next, it entered the endurance competition, the elite troops of General Rotten Heart, wave after wave of upwards, wave after wave of retreat, miner slaves came out in waves, and drilled back in waves, comparing whose physical strength was exhausted first.

And Batman knows that in this regard, the situation is not optimistic at all, the number of miner slaves is already small, and the physique is also weak, and the back and forth carrying stones, lighting logs, and throwing spears has almost exhausted the physical strength of all soldiers who can fight.

Not surprisingly, after about two days and one night of defensive fighting, the gate of the mine was breached.

But in Batman's opinion, the real battle has just begun.

Catch the herd and burn the rope
