Half an hour later, the ironclad locust swarm outside still showed no sign of leaving.

At this moment, with a "bang", an iron plate fell to the ground, and immediately, a square gap was exposed, and outside was a dense iron locust.

It turned out that the iron plate was used to repair the gap in the top of the factory, and after a long period of wind and sun, it had begun to loosen a little. Swarms of iron-clad locusts pressed on it, causing the iron plates to fall overwhelmed.

Several ironclad locusts suddenly flew down from the top of the factory, and the piercing buzz was unusually loud in the closed factory.

"Watch out there." Luo Chen was the first to react and hurriedly shouted. At the same time, the machine gun in Luo Chen's hand rang out.

In an instant, several ironclad locusts that flew in fell weakly and smashed into the middle of the soldiers.

Immediately, all the soldiers looked up. A strong light shone through the gap. The roof of the factory is made of thick steel plates, and at this time, there is a gap on it that can accommodate two or three iron locusts to pass through.

However, the ironclad locusts were all huddled together, next to each other, so that none of them could pass through at this time.

Seeing the delicious food below, the ironclad locusts became agitated with excitement, rubbing against each other, and wanted to enter the factory.

"It's dangerous to go on like this, and the ironclad locusts will rush in sooner or later." Luo Chen raised his head and looked at the gap, thinking in his heart.

At this time, Luo Chen's right hand was holding the big iron doorknob, and behind him, dense steel balls were suspended, like a layer of iron armor.

Suddenly, Luo Chen suddenly opened a gap in the big iron door, and then, the dense steel balls behind him shot out at great speed.

"Bang bang bang" dense steel balls hit the body of the ironclad locusts that did not react for a while, and in an instant, the layers of ironclad locusts outside the iron gate were shot down, and yellow juice splashed everywhere.

The rain of bullets did not stop, and batches of dense steel balls flew out of the wooden boxes that were opened behind them, and then the speed suddenly increased, and wave after wave shot out through the gradually expanding cracks in the door.

From the outside of the door, it looked like a fountain, and the silver steel balls struck the ironclad locusts at the doorway. The force of the steel balls shot out was not small, like bullets, directly through the ironclad locusts, and some ironclad locusts were even hit by multiple steel balls at the same time, turning into a pile of meat pieces.

After all, the ironclad locust is still an insect, and it is simple-minded, and it only knows how to rush forward. After seeing the crack in the door, the surrounding ironclad locusts crawled towards it, crowding towards the crack in the door.

Then, clumps of ironclad locusts were knocked away by a rain of bullets. A small pile of corpses had piled up in front of the iron gate, but the ironclad locust still desperately approached the crack in the door, like a heroic martyr.

"Good!" Luo Chen looked at the scene in front of him and shouted in a low voice. In this case, the huge number of ironclad locusts should be able to be eliminated.

The barrage formed by the steel balls continues, and the ironclad locusts continue to "commit suicide". Of course, there were also ironclad locusts that managed to dodge the rain of bullets, but with the sound of "bang bang" gunfire, they were all killed by the soldiers behind in one shot.

Controlling a huge number of barrages is not easy for Luo Chen, let alone continuous control. Luo Chen felt that the energy in his body was running out, so Luo Chen quickly picked up a test tube filled with evolution liquid and quickly absorbed it.

In the gap where Luo Chen absorbed the evolution liquid, without the firepower output of the barrage, a large number of ironclad locusts were about to rush in. At this time, dozens of soldiers lined up behind Luo Chen raised their rifles and pressed the trigger without letting go.

The barrage formed by the "Da Da Da" bullets covered outward at great speed layer by layer, and suddenly, as soon as a piece of ironclad locusts came into contact with the bullet rain, they fell silently.

Then, another rain of bullets spilled out, knocking down a layer of ironclad locusts. In this way, the rain of bullets confronted the ironclad locust swarm. For a while, the rain of bullets pushed the ironclad locust swarm to slowly retreat, and for a while, the ironclad locust swarm slowly pushed forward.

At this moment, a loud buzzing sound sounded. I saw that the ironclad locusts that were originally attached to the factory all flew up, and from a distance, it seemed like a cloud of black smoke rising.

In the distance, a flock of mutated sparrows flew over, their brown feathers reflecting the luster of metal like steel in the sunlight.

These ironclad sparrows were mutated from ordinary sparrows, which were originally less than the size of the palm of a hand, but after the mutation, they were the size of a door, and they looked like strong eagles.

Hundreds of ironclad finches flew over the factory at great speed, surrounding the ironclad locusts that wanted to escape, like dolphins rounding up schools of sardines.

"Chirp" Ironclad Cockles swooped into the ironclad locusts at great speed, and their strong and powerful black short beaks picked up the unfortunate Ironclad Locusts one by one, and then quickly swallowed them whole.

Like a sharp sword, the wings of the ironclad finch tightened, clinging to its body, and then quickly rushed into the swarm of ironclad locusts, and then, rushing out to the opposite side. In this way, the ironclad finches are eating away at their prey little by little.

The swarms of ironclad locusts that were surrounded flew around in a group like frightened deer, but they were all blocked by the surrounding ironclad finch.

From a distance, the ironclad locusts at this time were like a puff of black smoke, attacking left and right under the siege of the ironclad sparrows, trying to break out of the encirclement. In fact, they can be broken into pieces and scattered and rushed out. However, driven by animal instinct, they did not do so.

They are social animals, tiny individuals, and if they are scattered, they will be defeated one by one and all buried in the mouths of predators. So, they only have huddles.

Tightly surrounded, the ironclad locust swarm collectively flew towards the large iron gate that had been opened.

At this time, Luo Chen finally completely recovered his energy after absorbing more than a dozen tubes of evolution liquid. He saw a swarm of black smoke rushing from outside the big iron gate, it was a dense swarm of ironclad locusts!

The same dense rain of bullets covered the black smoke in the air, and for a while, the sound of gunfire echoed in the semi-enclosed factory.

"Boom" like rain, a piece of ironclad locusts fell.

However, it could not stop the advance of the black smoke. The back is surrounded by natural enemies, ironclad sparrows, and they can only hide in the factory.

Seeing that the black smoke was about to rush in, a fireball in Luo Chen's right hand quickly condensed. Then, the fireball flew quickly into the air outside the door.

As soon as the "boom" fireball came into contact with the black smoke, it exploded, shaking down a piece of ironclad locusts at the head of the row.

At the same time, the split rain of fire slammed into the ironclad locusts like fireworks under inertia.

For a while, a fire broke out in the sky, and the charred ironclad locusts fell one after another, spreading a layer of corpses on the concrete floor.

As if spiritual, the fire gradually spread to the rest of the black smoke, and the flames gradually expanded.

"Squeak" The ironclad locust swarm let out a miserable hissing sound. They scurried around, trying to get out of the fire. However, the swarm of ironclad locusts that had been ignited in the rear also followed, like a flaming tail.

The few ironclad finches that "chirped" into the locust swarm also screamed, and they accidentally rushed into the fire, and some sparks stuck to their bodies. Although the sparks were extinguished in a moment, the heat coming from them caused them to feel a painful burning sensation.
