The terrifying sound of air tearing came again, and the Gatling machine gun spiraled, tearing the newly resurrected metal rat.

The machine guns continued to sweep, and the bullet storm continued to sweep, tearing three big rats apart.

But the heart of chaos is still there, hanging on the tails of the three mice.

The source power is countercurrent, and the three torn big mice turn into metal ice crystal storms, then quickly condense and resurrect on the spot.

It’s just that the chaotic heart in the center is a little dimmer.

The mouse after the ‘resurrection’ continued screaming.

Wang Jun rushed over with his team members, raised his sword and killed the three rats. He waited for resurrection and continued to kill them.

Every time the mouse is resurrected, it becomes more ferocious; but when facing the siege, even if the mouse becomes stronger, it still has the fate of killing it in seconds.

And the chaotic heart, the mouse becomes dim every time it is resurrected; gradually, the chaotic heart is less than one meter.

Machine guns and rocket launchers aim at the tunnels on both sides to make defenses.

Everything is orderly, and the entire team is like an accurate war machine.

Looking at this crazy instant kill, Zhang Ping couldn't help asking: "Why should you wait for the mouse to condense? You can't kill it when it changes into metal ice crystals?"

Wang Jun quickly explained: "When it turns into metal ice crystals, it looks like wind and water flow, without force, and the damage is very small. It can be said that it is immune to physical attacks."

Zhang Ping nodded silently and participated in the attack: If you want to take away the chaotic heart, you need to exhaust the source power. Otherwise, the chaotic source power will affect everyone's safety, such as mutation or something.

But Zhang Ping looked at the system's prompt and could only sigh - these chaotic source powers are also source powers that the system can absorb.

However, it’s better to hide your skills. Don’t be too handsome, it’s not good for yourself.

Looking at the gradually shrinking chaotic heart, Zhang Ping felt itchy; what he lacked now is not the source power, but the contribution.

Finally, the source of the Heart of Chaos was exhausted, revealing its original body: it was not the perfect diamond shape of the Heart of Steel, but a spherical shape of more than ten centimeters, with a large number of bulges, which looked very similar to the new coronavirus. In short, it didn't look beautiful and a bit hideous.

Without the source power, the three mice finally died and could rest in peace - they didn't have to die.

A team member stepped forward and picked up the chaotic heart.

"puff……"

Suddenly a silver-gray steel whip covered with barbed steel whip suddenly pierced, instantly piercing the team members' chest.

This is a tail that looks like a spine, but it is several meters long, which is enough to pierce the cement wall from the top of the tunnel and hang down to the ground, at least four meters;

The root is half a meter thick, the tip is as thick as a calf, and the end looks like a scorpion's tail.

The team members struggled and screamed.

However, the barbarian has completely caught the team members' bodies.

The tail retracted, the cement layer above collapsed, and a huge metal monster appeared:

Its torso is more than two meters long, with thick scales all over it, and a flat body, completely a human body;

There are limbs, limbs have thorns, thick hind limbs, anti-joint joints, long forelimbs, and hands and feet have turned into flexible metal claws; the surface of the body is covered with thick metal scales.

The neck is a bit long, the head is triangular, the mouth is particularly large and long, and a sharp steel teeth with a mouth - real steel teeth; above the nose, you can also see the appearance of a three-point face.

The monster's tail retracted and stuffed the team member directly into his mouth.

"Click..."

The screams came to an abrupt end.

Defending on the three-sided tunnel, he did not expect the attack to appear from the top of his head.

Zhang Ping was still confused, and some team members were already screaming: "The monster in the old city, the long-tail predator! There must be another one!"

"Ahhhh..." Wang Jun roared, turning his hands into sniper rifles, designing close to the monster.

"Dangdangdang..."

The bullets hit the scales and jumped one after another, with only helpless Mars.

The long-tail predator swallowed a team member, and his long tail turned into a new God's convenience, sweeping Wang Jun.

"Boom..." A rocket came, and a violent explosion exploded to fly the long-tailed predator.

However, the long-tail predator was almost not injured, but was only blown away in the air, but also took the opportunity to pounce in front of a team member. His four-meter-long tail was like lightning.

The team member lay down flexibly, his tail swept from behind, bringing up a dazzling field of Mars. The team member's back was torn apart by the spikes on his tail, and it fell into pieces.

The explosion caused the collapse of the tunnel. It was originally a building that had been more than a hundred years ago, and a hole was broken by a long-tail predator above, causing structural damage.

However, the battle is in full swing!

Wang Jun yelled: "The machine gun is on the top!

As for grenades, don't save money.

Back to back, alternate cover, retreat in an orderly manner!”

The long-tailed predator refracts and jumps, and it is as fast as lightning in the narrow space. The machine gun explodes, but it is almost impossible to lock the target.

The bulky and inflexible machine gun almost loses its effect at this time. When the long-tail predator flies over the heads of the crowd, the machine gun has to pause.

Suddenly, the long-tailed predator flashed a few times and then jumped onto the machine gun.

The team members operating the machine gun jumped away.

A scalp tingling situation occurred: the long-tail predator actually lay on the machine gun and hooked the trigger.

"Boom! Boom!"

Several grenades fell, and the long-tailed predator jumped away, but the machine gun also scrapped and left.

The cement pieces fell on the top of his head, and pieces kept hitting Zhang Ping's head, making a tinging sound. Zhang Ping stuttered: "This... monster... is wise!"

No one answered Zhang Ping's question. Wang Jun yelled to command the battle, and his hands turned into sniper rifles, attacking the long-tail predator wildly.

Although it cannot break the defense, it can block its attack, allowing the injured team members to have a chance to breathe, and roll and crawl to Wang Jun.

Zhang Ping looked at the chaotic heart falling from a distance, feeling itchy. However, after looking at the distance, he had to meet with the brigade and prepare to retreat.

But at this moment, a heavy sound suddenly came from behind, with the sound of collapse, the sound of heavy objects falling to the ground, and the sound of metal collision.

Zhang Ping suddenly turned his head, but saw another long-tail predator appearing in the dark tunnel on everyone’s retreat!

Pinch mode!

At this moment, a clicking sound came from the muzzle in Wang Jun's hand.

Wang Jun's expression changed drastically: "There are no bullets! The grenades are used up too! Brothers, let's fight for bayonets.

The power of grenades is actually not as powerful as guns, so try to keep them for later use.”

Then his hands turned into swords and shields, and his face turned decisive.

Grenades are far inferior to guns for single-point destructive power to hard objects.

Especially at the moment, the grenade is slow and is directly avoided.

Two long-tail predators jumped flexibly in the tunnel. Zhang Ping turned into an oversized pistol with both hands, and the hit rate was pitifully low after a few attacks; those who hit occasionally could not break the defense.

Everyone collected their guns and began to change their cold weapons.

long knife, iron rod, axe, hammer, iron cable;

Some people even turn into a thick shield themselves.

Zhang Ping's right hand turned into a thick mountain knife, his left hand turned into a half-meter-sized grab, and his eyes looked at the one not far away:
Chapter completed!
