I have a magical world.

Flash displacement has unparalleled advantages.

No matter how tight the surrounding circle of flying monsters is, they are destined to be unable to engulf him.

The two M134 miniguns in Chen Xuan's hands continued to fire.

From time to time, a bat-winged demon or a poisonous vulture would spin and fall to the ground after being injured.

Even if you are lucky enough not to fall to death, you will be hit by nearby adventurers and mercenaries.

After killing dozens of flying monsters, the bullets in the magazine were exhausted.

The barrel of the gun glowed with a green light like hot iron felt, so hot it could be grilled.

But it was not directly burned red like the M2 heavy machine gun.

Because the two are not weapons of the same generation.

The M134 minigun is based on the M61 heavy Vulcan cannon.

So it is also called MINI Vulcan.

When it came out, the M2 heavy machine gun had already been in mass production and in service for more than half a century.

Both differ in structure and craft materials.

The M134 has six barrels, which are fired in turn under the rotation of the motor.

The wear of each barrel is not easy to reach the shooting threshold within a reasonable firing rate.

It is equivalent to six barrels "serving" this gun.

And it has two barrel specifications, one is carbon steel based on high-alloy chromium-molybdenum steel.

This alloy barrel is now widely used in most standard rifles.

For example, the famous AR series rifles.

Next is stainless steel, mainly 416 stainless steel, which has 12% to 14% chromium, low carbon content, good corrosion resistance, and good processing quality.

After being manufactured into a barrel, its service life is generally longer than that of a carbon steel barrel.

Its tensile strength can reach 7030.69 kilograms of force/square centimeter (kgf/cm).

The Rockwell hardness value is usually between 25-32.

The difference is that stainless steel barrels cost more than carbon steel.

It has not yet become popular among standard rifles, but most precision marksman rifles introduced later use stainless steel barrels.

The M134 vehicle machine gun is said to be "new", but it has been in service for seventy or eighty years.

It has gone through many modifications and design enhancements during this period, and has been fully updated. A more durable barrel has been used, and the shooting life will naturally be longer.

Of course, the M134 is a rapid-fire weapon after all, and its maximum rate of fire exceeds that of the M2 heavy machine gun several times. In addition, it has many electrified parts, so the overall loss rate can only be said to be half a pound.

But in the current situation of war, it is still very powerful.

As long as Chen Xuan is willing, after replacing the new magazine, the two M134 heavy machine guns can fight again!

However, the situation on the battlefield was changing rapidly, leaving him little time.

He only had five M134 machine guns in total.

In a hurry, Surape couldn't get more good stuff.

We can only wait until all the second-hand bacterial aid equipment is in place.

Use the storage compartment's ingestion ability to quickly put away weapons.

The monsters below have advanced to the third echelon.

Under the command of Tansen Mars, the adventurers and mercenaries fought and retreated, heading towards the location of the last large magic circle.

There will buy them time to evacuate back to the tower.

As the distance progressed, the long-range monster's offensive suddenly stopped.

They also need to move their position closer to the temporary defense line to ensure that their range can cover the rear.

However, with the flying monsters following up one after another, the pressure on the defenders did not get much relief.

The dozens of flying monsters Chen Xuan killed were just the tip of the iceberg.

After the first siege failed, most of the flying monsters decisively changed their targets.

Only a small group was left to continue fighting with him, while the rest all fell to the ground.

The bat-winged demon roared past people's heads, opening its mouth from time to time to howl out silent over-frequency sound waves.

Every sound wave can ripple in the air.

Adventurers who are attacked will be knocked away as if they were hit by a super-large pendulum.

The attack method of the poisonous vulture is rather disgusting.

While flying, their main attack method is to spray globs of rot.

I saw the rotten poison vulture's chest and neck stirring, and then a ball of dark green liquid the size of a melon flew out, and when it landed on the ground, it spread instantly.

If it directly hits the human body, it will quickly wear away and corrode the protective magic, and then melt the flesh and blood body into a puddle of smelly water.

In addition, the claws and sharp beaks of these poisonous vultures contain toxins. If they are exposed to blood, the toxins will explode in a short time.

Those who are infected may be paralyzed all over the body, or poisoned to death on the spot.

This made the retreating defenders miserable. They had to be careful about their steps at all times to avoid stepping on the rotten liquid.

As for those huge Heart-Destroying Demon Eagles, they are even more arrogant.

They were like air buses, roaring over the defense line.

It swooped down from time to time, and its huge claws could take away at least a dozen adventurers every time it swept the ground.

Roadblocks and barricades are as vulnerable to their claws as models.

Even the sturdy towers were as fragile as tofu in front of those giant claws that could break metal and break stone.

With the city crossbows in the peripheral direction withdrawing into the city in advance, these evil eagles seemed unscrupulous.

Arrows fired by Black Iron or Bronze level rangers cannot even break through Fei Yu's defense.

There are also earth-boring worms scurrying around underground.

They raise the ground and sometimes swallow adventurers directly on the ground.

The tubular mouth full of sharp teeth is like a meat grinder. It only takes a moment to squeeze and chew the unlucky eggs that fall into the mouth.

Therefore, the pace of on-site retreat was much faster than planned.

Moreover, it is said to be a retreat, but in fact it is a rout.

After the temporary wall collapsed, the ground front collapsed completely without lasting two rounds.

If the echelons were not arranged in an orderly manner in advance, simply escaping could cause stampede casualties.

The monsters were advancing by land and air, and it was normal that the makeshift garrison couldn't stop them.

The head-on battle between blood and fire still depends on the trained legion.

On the tower on the front line, Tanson Mars' expression remained unchanged, as if he had known that such a situation would happen.

"You go."

"The defensive plan at the rear remains unchanged."

"Activate the monster center when it crosses the freezing trap."

He said loudly to the flag soldiers beside him.

"Then...what about you?"

One of the flag soldiers asked quickly.

But he saw Tansen Mars lightly adjusting the buckle of his chest armor.

He took the two-handed giant sword engraved with flame patterns from the hands of the subordinates beside him with his backhand.

"As a lieutenant, I naturally have to fight for the city."

After saying that, he grabbed his sword and jumped down from the tower twenty or thirty meters high.

The magic essence gathered in his lower body, forming a cloud-like buffer.
