Tens of millions of rats came in mighty waves, as if a black curtain had been pulled over from a distance to cover the land.

When the high-level officials of the human camp saw such a large-scale rat tide, they immediately issued a series of command orders as if they had seen a ghost.

The human camp has done a lot of preparatory work to deal with the demons over the years, and it is naturally the top priority to inquire about the information and the realities of the demons.

The powerful reproductive ability of the Black Devil King's army of Black Devil rats was naturally feared by the higher-ups of the human camp, so they were preparing a way to deal with the Black Devil Mouse army a long time ago.

The mechanical battleship moved again, flew through the air, and threw bombs at high altitudes. The bombs exploded in the rat tide, capturing hundreds of demon rats.

The magic birds flew in the monster army, and the powerful monsters sat on the magic birds to intercept the mechanical battleships in the air, blowing up the mechanical battleships and mechanical airships, and the magic birds were also shot and killed. Do not withdraw.

The death and injury of the devil mouse is not small, but in the mighty rat tide, the dead black devil mouse can be ignored.

The rat tide rushed not far from the fortress, and a large number of knights carried iron pillars in the shape of obelisks and inserted them in front of the fortress. The number of these iron pillars reached thousands, standing in front of the fortress. At a distance of one kilometer, five lines of defense seem to be formed, interlaced with each other, covering a distance of about one kilometer.

At the same time, there were also quite a few knights who stayed outside the iron pillars. These knights had thick mechanical arms in their hands, completely covering their arms. Because the robotic arm is too thick and square, it looks extremely out of place.

"Come on, everyone is ready to inject the potion." Outside the iron pillar of the obelisk, a knight king shouted. He took the lead in injecting the potion, and the magic energy on his body began to riot.

"Thunderhand is on." Another roar, the control rings on the robotic arms on their hands bounced off, and arcs jumped out of the robotic arms.

This robotic arm is a lightning control and conversion device that can efficiently convert lightning magic energy into lightning, and the robotic arm has an enhanced magic array that can enhance the power of lightning.

They grabbed onto the thick cable that connected an obelisk's iron post.

"Everyone, behind us is the fortress, which is the most important line of defense for us human beings. If it is broken by demons, we humans will no longer have a chance to turn around, so you all bet everything and use everything to kill all these demon rats. "The King of Knights roared.

"Yes." All the knight-level voices were firm, and they regarded death as home.

The high-level human beings on the fortress are also watching the next confrontation with extreme tension. If the rat tide cannot be stopped, their pressure will be even greater.

"three!"

"two!"

"one!"

The knights in front of the obelisk iron pillar array were all nervous. Under the order of the king of knights, all knights released their magic energy. Lightning rushed out of the mechanical arm and rushed into the obelisk iron pillar along the cable. In the middle, the runes on the iron pillars of the obelisk lit up, flashing with thunder and lightning, and electric arcs moved forward to both sides, connecting the iron pillars of the obelisk in front and on both sides.

Those obelisk iron pillars that were not activated light up because they are linked to each other. This process is very fast. All the obelisk iron pillars light up in less than a few seconds, and all are beating arcs.

These iron pillars of obelisks are unremarkable despite their cumbersome size, but they are indeed masterpieces of human magic energy technology.

The surface of the iron pillar of the obelisk is engraved with a combined lightning array, and a lightning accumulation device is installed inside the iron pillar of the obelisk.

Human scientists have found a special metal that can temporarily accumulate lightning, which will be the kinetic energy of the obelisk's iron columns.

At this time, the army of rat tides also came. These devil mice all have blood-red eyes, and they look like crazy devils, like hungry ghosts. They are all infected with the Junkrat virus. Every devil mouse is overdrawing its life. Normally twice as strong.

The rat tide army didn't care about the obelisk iron pillar array flashing with thunder and lightning in front of it, and plunged into it. Some demon rats hit the obelisk iron pillar array and were directly strangled by the thunder and lightning on the obelisk iron pillar array.

When the army of the rat tide was about to pass through the iron pillars of the obelisk, the king of knights immediately shouted: "Kill!"

In an instant, all the magic energy in the knight-level body was poured into the mechanical arm, and stronger thunder and lightning burst out from the mechanical arm, and then the entire obelisk iron pillar array released extremely terrifying thunder, and these thunders were linked to each other to form a terrifying thunder and lightning interception Net, the demon mice in the iron pillar formation of the obelisk were all electrocuted in an instant.

The army of demon mice in the rear rushed forward desperately, and they were ruthlessly strangled when they entered the iron pillar formation of the obelisk.

This obelisk iron pillar array just stopped the army of demon rats. Every second, hundreds of demon rats were killed by lightning and the corpses were almost filling the obelisk iron pillar array.

Moreover, a powerful demon rat came from behind and began to destroy the obelisk iron pillar array. Many obelisk iron pillar arrays have been knocked down or even destroyed, and the obelisk iron pillar array is failing.

"Damn, there are still fewer thunder formations." The high-level human expression above the fortress was ugly. In fact, about seven or eight thousand iron obelisk iron pillars were made~lightnovelpub.net~ But these iron obelisk iron pillars are all distributed in For each fortress, they only have more than 1,000 roots here.

If there are seven or eight thousand obelisk iron pillars forming a thunder array, it can definitely cause unimaginable destruction to the rat tide.

The king of knights noticed that the obelisk iron column formation was taking effect, and he immediately roared: "Evolution."

All the knights burst out with more energy, and the obelisk iron pillars that were inserted into the ground suddenly rushed out of the surface and suspended in the air.

The thunder and lightning still flashed outward, and each iron pillar of the obelisk had more than a dozen thunderbolts, which still killed the attacking demon rats.

These obelisk iron pillars began to tilt, parallel to the ground, and then more intense lightning erupted. These obelisk iron pillars were linked to each other, forming a huge lightning network in the air.

"Release with all your strength." The King of Knights roared with determination.

The thunder and lightning on the iron pillars of the obelisk suddenly increased several times. These iron pillars of the obelisk suddenly slammed forward, directly hitting the rat tide. The extensive thunder and lightning bombarded the rat tide, causing huge casualties in an instant.

The iron pillar of the obelisk moved forward all the way, and the thunderbolt shot through the army of demon rats like a power grid, taking away a large number of demon rats' lives.

In just a few seconds, the iron pillar of the obelisk rushed out of the kilometer distance. Wherever it passed, almost all the demon rats died, and the number of dead demon rats reached as many as one million.

The powerful demon rat in the rat tide couldn't help but knocked down the iron pillar of the obelisk to the ground, making it impossible to cause further damage.

Thousands of obelisk iron pillars fell to the ground one after another, causing a lot of casualties, and at this point, the obelisk iron pillar array also failed.

However, the destruction effect caused by the obelisk iron column array is quite huge, at least causing four or five million demon rat casualties, but the demon rat army is still huge.
