Bunkers are one of the most important forms of combat in human history. Pen & Fun & Pavilion www.biquge.info

For quite a long time, human beings, who were born weak and did not have outstanding racial talents, have been the objects of various races at will. There are even alien races that specialize in tracking humans as they move around. When people find the ideal habitat, they take their place and even kill them. And human beings can only swallow their anger.

Some of the prescient people began to think and act for a long time. The proposition is how humans, who do not have enough combat power, should have strong measures to bridge the gap between the two sides when they are on the defensive side. Numerous tactical studies, fortifications, and bloody "hands-on activities" were carried out.

From the popular and ordinary shield arrays, to the rudimentary defensive ravines, to the appearance of artificial fortifications ,—— bunkers in the shape of inverted bowls. A variety of tactics were constantly developed around this, and this defensive formation, which was nicknamed the "Wangba Tactics", broke out with unexpected brilliance in history.

But this is something that has had a profound impact on human history. The earliest design ideas came from an ordinary general.

It was in a special operation a long time ago, and this soldier, whose name had been erased by time, encountered an alien elite who had seen clues and came to intercept him.

At the critical moment, this man had a whim, and in the blink of an eye, he devised an excellent battle plan.

Well, it's actually a semicircle of countless branches bent together, and a very dry heavy chemical oil is poured on it. Once they've solidified, leave a few windows that look like they've been inhabited. Bell, bell...... A freshly baked trap that looks like a suspicious stronghold.

However, it seems that there is a little bit of something missing. Hundreds of pounds of black powder? Oh, no, no. Humanity wasn't as miserable as it is now. What they took out was the rare goods in the hands of the dwarves,—— and this terrifying little guy only needed half a catty to send everything within a radius of twenty meters to the sky. And in order to make the trap look more realistic, the brilliant general arranged several devices around it for concealment.

Now, people just have to wait and see.

He is really an outstanding general, the tactical set-up, the field setting, the adaptability, everything is so perfect and reliable. The alien elites who came here to search didn't even find a suspicious building near them...... , I didn't find it...... ,(⊙_⊙),~~ It's embarrassing......

At that time, the heart of that outstanding general was broken. When the enemy just skipped the trap from the side with ease. In fact, at one point, he wanted to jump out and fight these bastards who ignored the fruits of his labor. And in the end, it did. This tells us that the basic skills are too solid.

Ahem, back to business. The trap is no longer working, but trying to slip under the noses of the celestials is like a fantasy. I don't know what news they got, but the overwhelming array of probes on the way through them is not framed.

It was at that time that the earliest prototypes of bunkers appeared.

It is written in the history books...... The brave and fearless unsung warriors took the initiative to expose themselves, centered on the trap that had not been triggered, and used themselves as bait to start a desperate struggle, and finally won the victory.

But there is no victory. It should be after the end of the road, and finally detonated all the mountains and ended up together. And that secret operation was also in vain with the celestials who rushed to the back.

However, that general's unique combat method was excavated by those who had a heart, and gradually evolved into a unique defensive formation of human beings - the bunker group, Wang Ba...... (This is omitted (╯3╰)).

For example, the current shelter. underground ruins,

Angry ogres, stripped of their sacrificial restraints, have left the battlefield in chaos. Some are desperately attacking human hideouts, some are just engaging in senseless destruction, and some even get involved in scuffles with their own clans.

Although the whole scene was chaotic, the human casualties were bearable. The frail old mage stood on the shoulder of Rouse, who was traveling across the battlefield, observing the changes in the vicinity. And the ogres around them seemed to be out of sight of this conspicuous target, leaving them unobstructed.

The shelter that has been uncovered for its true face feels like a large cemetery, and there are grave bags with several holes open everywhere as far as the eye can see,...... Hundreds of bunkers. These dirt bags, which were buried on the second floor of the basement, finally came into use.

Countless bunkers form a huge bunker group, relying on each other to cooperate. From time to time, a few crossbow arrows were shot inside, or a bunch of explosives were thrown, and the nearby ogre, who was flying around dangerously, directly used himself as a meat shield and smashed open the walls around a bunker. The hapless ogre had just put his head in for the last moment of his life,—— and the people inside did not hesitate to detonate all the explosives in the bunker and chose to die together. This kind of U-turn injury is no longer something that can be cured by the super self-healing power in the dark.

This is a scene that can be seen everywhere on the battlefield of the Vault, where the frail humans maintain an eerie balance with the ogre forces without the dispatcher, and the battle continues to stalemate.

However, this so-called false balance is only for the common species, not for the monsters that have been mutated.

Not counting the one-eyed ogre who had been hovering around the dead Two-Headed Sacrifice. The eight brute twisted sinew giants are simply blue tanks with infinite power. Just by virtue of the powerful kinetic energy of running, this battlefield has been turned over and over again. They kill more than a dozen times faster than normal ogres. In the blink of an eye, more than thirty people are going to remain on this land forever.

"Have the children, women, and old people all been transferred?" Arriving at a dark corner of the shelter, the Demon Warrior Rouse gently lowered the old mage in his hand. As soon as he landed, the old mage immediately asked about the current situation with an ordinary stone.

"It's all ready, just waiting for your orders. ”

The stone moved as if it were an illusion, and then it was no longer alive.

The old mage turned his head, looked at the already devastated shelter, and said slowly and heavily.

"Then tell all who are still alive to retreat, and go through the second secret passage. I'll take care of the rest. ”

“......”

......

At any time, advanced means of transmitting information on the battlefield are one of the important means to enable the armed forces to advance and retreat in a measured manner and seize the opportunity.

Wood spirits convey words through the magic of nature, dwarves convey instructions through mechanical combinations, orcs convey opinions through loud wolf howls, and celestials convey commands through unpredictable light.

So what do human beings rely on to construct the channels for information transmission?

The people who retreated suddenly and massively left as if they had been instructed to leave regularly. Although there were small amounts of chaos, the bunkers that were detonated one by one managed to stop the ogre horde from advancing.

In order to evacuate, it seems that all the explosives produced or searched by humans in the ruins over the years have been thrown into this battle for survival.

And without the command of the sacrifice, these irrational madmen are simply a mess of sand, and they don't even care about the targets fleeing around them.

As for the eight brute mutant "dominant species" that broke through the line of fire. At least thirty or so demon warriors will hold these beasts as long as possible.

If one could see through the layers of earth and the confines of the realm of the gods, they could look down on the entire underground ruins. He would find that there were several special places in the shelters full of explosions. The flames echoed with the smoke and the retreating people, forming a tacit cooperation.

It is the most important information transmission tool for human beings, the first order magic weapon second only to the enchanted wooden stick in terms of cheapness, and the greatest and cheapest invention in the history of mankind and even the history of the world - the beacon tower.

"Let the broken people leave quickly. The old mage, who had just recovered his strength, struggled to his feet and said to a few junior mages who were using their staff to control the center of the circle.

"We're going to collapse here!"
