The power was interrupted, but there were still many batteries in reserve in the warehouse. Luhe Group started with batteries, and the efficiency of this battery is self-evident.

Lightning took advantage of the more than ten hours before the demon army attacked, commanded his engineering troops, and restored the base stations in several key locations. A single Luhe battery is integrated into a battery pack, and through an external inverter, the DC is converted into AC power that can be used by the base station.

As the rat demon retreated, the communicators of the city defense soldiers lit up one after another. Everyone was jubilant, thinking that the power supply was back to normal. But then came the order that only the communications were partially restored and ready for battle, and there was another wave of frustration.

The power of the battery can supply these low-energy base stations, but if it is connected to a powerful electromagnetic gun, it is estimated that the batteries in stock are not enough to fire two guns. This kind of super-energy-consuming combat unit can only be driven by fusion reactors, otherwise a thermal power station must be built behind each electromagnetic gun.

In addition to base station communication, lightning also needs to restore the defense function of the spirit demons of the city wall, which is almost the most important defense facility of a human city.

In the early days of the confrontation with the demons, the spirit monsters caused terrible casualties to humans. The human soldiers rallied into a defensive line and even had the courage to confront a certain number of mountain spirits head-on.

But if a ghost appears among the enemy, it will be devastating to the morale of the human race. Because the attacks of ordinary people are ineffective against spirits.

Only a cultivator's aura attack can harm these disembodied monsters, and no matter how powerful the firepower of ordinary humans is, they can't stop the resentful spirits for even a moment.

Once they are approached by the spirits, they can possess the bodies of humans. The possessed will be controlled by resentful spirits and kill their fellows. Even if the possessed person is killed, it will not hurt the resentful spirit. They will float out of the corpse and continue to plague their next target.

And that's not all, spirit monsters can still pass through walls, even if they hide behind the walls, it's not safe.

In the beginning, human beings had no way to deal with spirit demons, and if there were no cultivators in charge, there was only one way left to scatter and escape. But after all, human beings are a species that stands at the top of wisdom, and they are very good at summing up experience, especially when it comes to life and death.

In the long-term confrontation, humans discovered three weaknesses of spirit demons.

The first is the fear of sunlight, so spirit demons will only act at night, or in places where there is no sunlight.

The second is that spirits can pass through many obstacles, but they can't pass through static electricity. If a wall has a certain amount of static electricity on it, the spirit will bounce off as it passes through the wall.

The third is that the possession of the spirit body is not incomprehensible, as long as the possessed person is pressed down, the heart defibrillator can directly fly them out of the person's body. The possessed person will become seriously ill afterwards, but he will not lose his life.

These are the three means of self-protection for ordinary humans when facing spirit monsters, and it seems that electricity can effectively damage spirits. But humans have tried Nether***, and even high-voltage arcs against spirits, but the effect is very average. Until now, only the spiritual attack of the cultivator, or the sunlight, could truly destroy the spirit.

Four giant static generators are located in all four directions of the Coastal Wall, which activate at night to cover the alloy surface of the wall with a sufficient amount of static electricity. If resentful spirits come in on a large scale, the static electric field will keep them out of the walls.

But because of the power outage, the electrostatic generator naturally could not be activated. It's daytime, so don't worry about it for now. But once the sun sets, the demon will send out resentful spirits. No more, even if it is only a thousand, the entire Marina City will be finished!

Lightning had to use this daytime to scavenge more batteries and restore the function of the static generator anyway.

But what he didn't know was that his efforts had no practical significance. Because of the demon alliance, a large number of resentful spirits and earth spirits have been withdrawn.

The demon general succubus single-handedly paralyzed the power system of the sea, and was seriously injured as a result. Because of moving mountains to protect her, the other two demon generals couldn't play any tricks anymore, so they had to agree to let her go back to the Venerable to heal her injuries.

When she left, she also took most of her subordinates away. This time, the four demons will join forces, and most of the spirit demons are the subordinates of the succubus. In the end, she symbolically left the witch king with two hundred resentful souls, and the hated witch king's teeth itched.

It is impossible to steal chickens at night with these two hundred souls, the number of cultivators in Binhai City is very small, but it is not impossible, and it is not impossible to send it to make any big waves. In the end, it is necessary to harden the coastal wall.

At this time, the Witch King and the Great Emperor stood on the original mountain peak, watching the battle from afar.

The half-broken group of rat demons fled back, squeaking and licking their wounds at the foot of the mountain. The Witch King was distraught.

The Witch King has always regarded himself as a tactician, and this time the tactic of the mountain elves taking a ladder to open the way for the rat demon group is his new invention.

The last time the Tin Zombie exploded into a skeleton thrower, it was also his invention.

He is always inventing all kinds of bizarre tactics, which are called "class matching".

It's just that the effect is poor every time, and now I can't help but feel resentment in my heart. Why can't these humans obediently cooperate with his ingenious tactics?

The damaged mountain spirits are all Yishan's subordinates, but this demon general is not like a charm spirit. He was silent, and no one could tell what was going on in his mind.

However, the emperor slightly raised his dissatisfaction with the witch king.

"Forty hours have passed, and now thirteen hours have passed, Witch King, don't waste any more time playing your tricks.

If you want to fight, you will fight with dignity!"

The first two attacks were both commanded by the Witch King, but both ended in failure. He had now lost the confidence to command again, and even if he wanted to, the Emperor would not let him do it again. Therefore, the witch king had nothing to love, shrugged his shoulders and said, "It's all up to the emperor's arrangement." ”

He was really hit with confidence.

"Good!" the Emperor's muffled voice rumbled from his armor and turned into a roar that resounded through the mountains. He drew his greatsword and slashed it in the direction of the sea, "The general attack begins!"

After the rat demon fled, the human soldiers descended to the outside of the city walls to clean up the battlefield. No one knows how long this offensive will last, so it is necessary to hurry up and set up the battlefield.

Previous encounters proved that the sluggish type of trap of wire mesh was ineffective, and the soldiers switched to more effective anti-tank mines. When the mountain spirits attacked, only these mines had the most success. As soon as communications were restored, the logistics department deployed a container of anti-tank mines.

In addition, there were several cultivators who followed to clean up the battlefield. Although the mountain spirit and the rat demon are very low-level monsters, there are still some materials on their bodies that can be recovered.

The mountain spirit's eyes are obsidian the size of a watermelon, and when properly handled, this thing can be used to make armor tablets, which slightly increase the practitioner's defense.

The two front teeth of the rat demon are also good, and if they are embedded in the tool, the efficiency of digging holes can be increased several times.

Because of the demons and the human race, the productivity of the entire society has been hit hard. So a few years ago, humans began to fight by war, collecting some usable resources from the corpses of demons.

Of course, this work is still in a very basic stage, and what can be used and what cannot be touched on the demon corpse is not understood even by the cultivators who lead the team. There are often some accidents, so the collection is done with care.

The soldiers led by Yu Tianyu had just removed four obsidian eyeballs from the wreckage of the mountain spirit, and the alarm sounded at the head of the city. Everyone had no choice but to put down their work and immediately take the lifting platform back to the top of the city wall.

This time, the enemy is not so simple.
