It didn't take long for more detailed information to be transmitted, and a group of flying beasts appeared in the sky above the factory, and this group of flying beasts with iron-winged birds as the main members was attracted by the smell of blood just now.

Wang Hui and the others were all paying attention to the tide of alien beasts on land just now, forgetting that the corpses of the horned beasts produced before allowed the factory to avoid the opportunity to face the tide of alien beasts, and at the same time attracted predators.

This group of carnivorous beasts has the ability to fly, maneuvering more than other carnivorous beasts, and reaching the sky above the corpse first.

It is also Wang Hui who has recently become accustomed to ground warfare, especially focusing on various attack and defense considerations underground, but has missed the placement of detection magic weapons in the air.

Iron-winged birds, known for their strong iron wings, coupled with acceleration when flying, their attack on enemies is simple and brutal, but very effective, diving from high altitudes, sweeping the target in an arc, and the wings that are accelerated to the extreme will easily cut through any object like an oscillating knife.

And this group of flying beasts boldly captured all the carcasses of the horned beasts left on the ground into the air, and just now in order to eliminate the hidden dangers, dozens of iron-winged birds went around at great speed, and the pillars of the observation platform placed on the top of the factory were all cut off, so that there was a follow-up to the collapse.

The detection weapon was not aimed at the sky, but Wang Hui could also guess from the blood droplets and flesh that fell from time to time that the sky would become their feasting ground, and the tide of alien beasts that were still flowing on the ground had no intention of staying.

Even though there was a lot of blood dripping on many passing beasts, these herbivore beasts still moved forward as usual, on the contrary, they felt much faster before, especially the area of the factory, which was suddenly vacated, and I don't know if it was the iron-winged bird relationship that was still biting the corpse in the sky.

The passage of time seemed much faster under the endless tide of strange beasts, and before the flying beasts above had eaten the hundreds of corpses, the night outside began to fall, but the surging tide of strange beasts still did not decrease at all.

Wang Hui also sweated in his heart, it seemed that he was still too optimistic, he did not accept the willingness of the task force to let him evacuate all, but wanted to take the opportunity to get a handful, if it wasn't for the mistake of letting the tide of strange beasts avoid here, maybe he would not be able to hide underground and retreat.

The sun set, Wang Hui began to order the start of the shift, in this kind of combat environment, if there is no rotation, they will have a nervous breakdown in less than a day, and fight against the terrifying atmosphere outside for a long time, so Wang Hui's subordinates are all monks in the foundation building period, if they are ordinary people, four hours is enough for them to be schizophrenic.

Alien beasts are not only physically strong, but under the long-term battle of monks, a variety of cultivation characteristics also follow, especially the sense of spiritual oppression, each alien beast is like a thorn aura, and the multiplied aura characteristics under the group characteristics are enough to suppress the mentally weak to death.

However, as the night came, a killing was about to begin, but this time it was Wang Hui's side that started.

The flat top is just enough for them to rest, especially at night, when the light becomes less, and the night-blind night activity ability of the iron-winged bird is weakened by at least half.

Wang Hui didn't want to continue to have a group of iron-winged birds that would gather more companions to fly on the top tomorrow, so he didn't know when he would be trapped to death, and after careful planning, Wang Hui, who confirmed that it would not interfere with the follow-up intentions, instructed Yinhe to use some preset attack weapons.

Although the ground factory was evacuated by Wang Hui early in the morning, there were countless mechanisms and offensive magic weapons in a large factory building, and in order to prevent the iron-winged bird from destroying the factory, some of the anti-air magic weapons began to be activated.

A large area of the roof was rendered red, and this red with the smell of blood naturally came from the feet of the iron-winged bird, and after the surrounding area was completely dark, the entire flock of more than eighty birds all fell on the top of the factory.

Following their fall, there were more than a dozen broken corpses of horned digging beasts that had not been eaten, after all, there were not many iron-winged birds, and they could not eat more than a hundred corpses at once, and the remaining blood in them was constantly flowing on the roof, little by little, it colored the roof that was becoming more and more red.

Groups with ethnic characteristics will naturally have various distribution patterns, and this group of iron-winged birds quickly assigned the outer patrols, the inner circle guards, and the core protected members, and operated very efficiently.

However, under their feet, which they could not perceive, circles of supporting iron pillars were pushed out of the narrow aisle space, and the semi-activated magic weapons were transported, and soon piled up under the iron-winged birds, waiting to be activated.

Time passed, at twelve o'clock in the middle of the night, except for the never-ending tide of strange beasts, most of the iron-winged birds had already sunk into sleep, and most of the guards patrolling the periphery were also drowsy.

After all, it can be regarded as a flying family, except for those who are also flying beasts that can fly up to the top of the factory building with a height of more than ten meters, the other herbivorous beasts have no ability to come up.

Yinhe pinched the time point and activated the magic weapon, and in an instant, small holes about one meter apart were revealed on the top of the originally flat workshop, and the inside was pitch black, and the activated magic weapon only poked out a slender round tube.

Before the surrounding iron-winged birds could wake up, the thin tube began to spray into the air, and all of a sudden, brilliant fireworks burst in the air, and the brilliant sparks like meteors fluttered in the wind, covering the entire field where the iron-winged birds gathered.

This is not a simple performance, as Mars covers the iron-winged birds, and a smear of blooming blood appears on the iron-winged birds, these seemingly harmless sparks are actually a kind of chemical infiltration.

Usually it is just a harmless solid existence, once it comes into contact with the skin, it will penetrate the surface layer in an instant, contact the internal blood vessels, and then the blood will have a blasting reaction with it, like a small bomb, and the blood vessels will be thrown to you and blown into pieces.

Under the dark night, the top of the already red factory was covered with a layer of blood red, but this time the source was from the blood in the body of the iron-winged bird, and the blood in the air was too frequent, and the condensation formed an area surrounded by blood mist for a short time.

The long thin tube did not retract after the eruption, and after the iron-winged bird could no longer chirp hoarsely, a liquid accompanied by a strong smell was sprayed in the air again, and then the thin tube retracted, and the top of the factory returned to a flat state, except for the corpse of the iron-winged bird in one place, as if nothing had happened.
