Although the endless darkness made the defense of Guangshi Base City more and more difficult, and the ability of the evolved body to shield electromagnetic wave detection methods such as radar, it almost made the military region blind from three kilometers away.

Fortunately, the single-photon detection technology of the 5 th Military Region has already achieved some results, and a single-photon detection tower has been built in the missile launch center, which has a complete set of single-photon detection systems in the tower, which can detect things hundreds of kilometers away.

Single-photon detection technology uses the new photoelectric effect to count the incident single photon to achieve the detection of very weak target signals. The single-photon detection system has extremely high detection sensitivity, and even for stealth aircraft such as F-22 and B-2, the range can reach hundreds of kilometers, and stealth aircraft can be detected at extremely long distances. At present, the only countries in the world that can produce complete sets of single-photon detectors are Switzerland, China, and the United States.

However, the single-photon detection technology also has some shortcomings, such as the huge amount of computing required, the size of the machine is too large, it cannot be shipborne or vehicle-mounted for the time being, and the detection effect of things stationary on the ground is weak.

Although single-photon detection still has many flaws, it is enough for a tidal wave of monsters, and a single-photon detector is able to detect a group of monsters a hundred kilometers away.

Eternal night falls, the fog rises, and the monster's roar grows clearer and closer.

It was impossible for the military region to let the Pandora creatures take the lead in attacking, and in the sixth minute of eternal nightfall, the photon detection tower had already locked on more than twenty monster dense spots.

Later, more than 20 DF-5 tactical missiles rose from the launch base, spraying dazzling flame tails, as if tearing apart the night sky.

A few minutes later, more than a hundred kilometers around the base city, twenty-six mushroom clouds lit up, some large and some small, some near and some far, but all of them were bright, slightly illuminating the night sky.

Boom Boom Boom ......

Five minutes after the mushroom cloud was in full bloom, the sound of a nuclear explosion was heard one after another by the people in the base city.

Prior to this, the military region had already received the results of the nuclear explosion, and the results of the nuclear strike should be not bad, because the second batch of nuclear missiles had been lifted into the air before the sound of the explosion came back.

With such intensive use of nuclear bombs, everyone's hands are sweating, but there is no choice between death and radiation.

Before the outbreak of this war, Qihuang Pharmaceutical had already begun mass production of potassium iodate tablets. Potassium iodate tablets are the simplest to produce, the easiest to obtain raw materials, and the most effective anti-radiation drugs.

Of course, this so-called good means that it can effectively resist the effects of mild nuclear radiation on the thyroid gland, but for people in the ruins of a nuclear explosion, it can only be regarded as better than nothing. Fortunately, the nuclear explosions are all 100 kilometers away, and they are all small-yield tactical nuclear bombs, and only some of the nuclear radiation particles will drift into the base city, as long as you are prepared to prevent radiation, human beings can still tolerate it.

Thirty minutes after the first nuclear bomb exploded, the Pandora monster gradually appeared in the night sky and above the vast land. At first, there were black dots, and the black dots gradually increased, and soon they were connected together, densely covering the sky and the sun. The black dot grew larger again, slowly revealing the image of a Pandora creature.

Flying and hovering in the air are Scorpion-tailed Pterodactyls, Discharge Wind Snakes, and many strange mutated birds of prey. Roaring on land are Cerberus, Lickerland, Helldog, Invisible Worm, Abomination Roshan... ・・・

At such a distance, the invisible insects did not enter the invisible state, after all, they need to consume energy, and when they get close to the base city, the invisible insects begin to become transparent one after another, activating the invisible organs.

In addition to these monsters, Du also meets a new Pandora creature, the Bristleback.

"Bristleback" is a popular name among the Awakened, and there is also a name for "Hedgehog", and in the military's monster information, this Pandoran creature is named "Brilbacked Boarmon".

The steel-backed boar beast does resemble a wild boar, but it is much larger, the size of a double bed. And it can make a pig grunting sound, and when it is hit hard, it will also make a pig killing sound, as if the sound effect is made of Dota Steelback. And there are also long steel spines on the back, hence the name.

The Brilbacked Boar is a level 5 Pandora creature with a body strength that surpasses the three-headed dog of Hell, and is a ground bulldozer hatched by a third-stage corrupted giant tree. …,

The steel-backed boar has 128 arm-thick spikes on its back, like the spines on a hedgehog's back, these spikes are not actually made of metal, but they are no less hard than steel.

The spikes on the back of the steel-backed boar usually fall backwards and stick to its back. In times of rage, the long spikes on the back stand up, even pointing forward. When necessary, the Brilback Boar will shoot spikes out with an explosion of extremely compressed dark source force.

In the previous life, it was calculated that the initial velocity of the spikes shot by the steel-backed boar beast reached more than twice the speed of sound, which was almost the same as the initial velocity of the bullet of the Barrett heavy sniper, and the power was very terrifying, and it could pierce through an entire row of humans.

Du Fei clearly remembered that in his previous life, he was almost killed by this kind of steel thorn hole through his body, and it was Ouyang Xiu who risked carrying him back to the base city.

In addition, there is a small hollow sac in the middle of the spike, which stores corrosive venom, and when the spike hits a hard object, the venom will shoot out of the sac. So, when the spikes are driven into the tank's armor, the venom sprayed will also corrode a hole in the tank and poison the driver inside.

It can be said that the steel-backed boar beast is the tank of Pandora's creatures, although it is smaller than the human tank, but in terms of mobility and combat effectiveness, it completely surpasses the mechanical tank.

Du Fei naturally remembered the information of the steel-backed boar beast, but he hadn't gotten the corpse of this kind of monster before, so he couldn't pass it on casually. What's more important is that at first, I didn't expect the steel-backed boar beast to appear so soon, I originally thought that only invisible insects would appear in the first war, but I didn't expect that both kinds of big killers would appear.

Fortunately, there aren't many of them, and they don't pose that much of a threat in the city. If it is in a plain war without the use of nuclear bombs, a platoon of steel-backed boar beasts can bulldoze a division of human troops, of course, provided that the level of awakened on the human side is too low and the number is too small.

The Pandora monster group approached the base city, and thousands of artillery batteries erupted one after another, and tongues of red flame spat out various cannonballs.

Super-large caliber fortress guns, tank guns, howitzers, high-energy lasers, source energy cannons, particle beam energy cannons, all kinds of piercing shelling sounds are intertwined, and the flames of the explosion reflect half of the sky.

The bullets of heavy machine guns and electromagnetic sniper rifles frantically tore through the air, weaving into a shrill metal barrage that blocked the charge of Pandora's creatures. To be continued.
