After moving forward for more than ten meters, Zhang Ping's eyes widened and the doubts in his heart were resolved:

There were seven or eight silver-gray metal mice in front of them that were bigger than humans;

Each metal mouse stretched out a thick tail like a steel whip.

The tail circled together and finally supported a huge metal flame.

The surroundings were illuminated by gorgeous metal flames – it was a wide three-junction passage.

These metal rats made a faint squeak, and huge and strong mice gathered around them to receive the transformation of their source species.

Most of the transformation failed and was immediately swallowed by a circle of large metal mice; it turned into source power again and poured into the huge source species in the center.

Suddenly, a huge metal mouse facing Zhang Ping and others suddenly stood up and made a shrill squeak.

The walls of the tunnel ahead suddenly twisted, and then a dense array of "metal monsters" appeared.

Before Zhang Ping could see clearly, these metal monsters turned into a torrent of steel with a roar, rolling towards Zhang Ping and others.

Wang Jun screamed: "Rocket!"

The team members have high combat qualities.

In a hurry, a rocket flew out and flew straight towards the "Heart of Chaos".

As the rocket was about to hit the chaotic heart, the big mouse jumping in front suddenly jumped up and opened its mouth.

"call out……"

The rocket penetrated into the mouth of the big mouse.

"boom!"

The fire bloomed, and the gorgeous light illuminated the tunnel. A large number of metal debris splashed and hit the wall. A spark appeared on the other mice.

The part above the neck of the big mouse was directly crushed; the remaining body rolled over the heart of chaos and hit a big mouse behind it.

Angry squeak came, and huge metal mice stood up.

At this time, with the explosion of fire, Zhang Ping saw the true face of the "steel craze":

These dense metal monsters can vaguely see a little bit of the mouse's shadow, which is completely hideous.

Some of these "metal rats" are wearing thick iron armor, which have prismatic bulges to enhance defense;

Some of them had hair all over their bodies like needles, and needles kept shooting out as they moved forward;

Some of them are completely covered with steel skeletons, with sharp claws and toes, and move like wind and as fast as lightning;

Some of them have strong ejection ability and can bounce forward, and they can actually avoid machine gun strafing.

The light of the explosion flashed, the tunnel began to tremble, and large tracts of cement, rusted steel pipes, etc. collapsed and fell.

Of course, many metal mice were also blown away by shock waves and rolled towards Zhang Ping and others.

Almost at the same time, machine guns roared;

The six-tube Gatling machine gun rotates, and the muzzle makes a sound of tearing the air;

The tracer bullet was like a whip of God, slapped hard on the torrent of steel composed of metal monsters.

The metal bullets collided with the metal mutant rat, and Mars shot everywhere, and the clanging sound echoed.

Pieces of mutated metal mice were torn apart, and the collapsed metal fragments filled the entire tunnel for a moment.

Everything happened in an instant.

The tunnel was collapsing, the machine gun was roaring, and the fire illuminated Zhang Ping's cheek;

Super metal rats are roaring, and more mutant metal rats are sprinting like metal frenzy.

Loose cement fragments falling from the top of the head made a sound when they hit the head.

Zhang Ping looked over his head with some concern.

After waiting for a while, the cement debris stopped falling and did not collapse. The quality of the tunnel is good.

Wang Jun yelled: "Suppress the grenade and machine gun, and retreat."

Everyone retreated in an orderly manner, Zhang Ping pushed the cart, and there were team members sitting on the car, machine guns roaring, bullet shells slamming down on the ground, spreading all over the floor.

During the retreat, Zhang Ping took the time to roar: "Is the Rat King dead? Just kill the Rat King, right?"

The team members who operated the machine gun yelled and responded: "The Rat King is not a mouse. The seven or eight big rats we saw just now are called the Rat King. Killing one or two is useless!"

"Oh?" Zhang Ping was stunned. It turned out that the elite monsters could be a group!

Everyone retreated for a while, and when they were about to retreat to the position where the bomb was left, the mouse stopped.

Zhang Ping clearly saw that it was all dead.

The battle time is less than 10 minutes.

Yes, these mice are crazy, weird, and brave.

However, humans are born to cheat: in less than ten minutes of battle, the machine gun has used up half a box of bullets.

Although metal rats are crazy, they are too low-level after all.

Zhang Ping couldn't help but wiped a cold sweat - well, the metal's palm rubbed over the metal's cheeks and made a harsh sound.

Actually, I don’t feel any sweat after transforming, it’s just a habit.

Fortunately, no one cares about Zhang Ping's little stupidity now~

As the squad leader, Wang Jun ordered: "Go forward, clean up all the mice, and pick up the source species!"

It took so much to see that the mice were all dead, so of course they had to collect the spoils.

Zhang Ping looked at the end, and there were still three large rats with knots in front of him, and the center was a huge "heart of chaos".

Seeing this thing, Zhang Ping was jealous: 1,000 contributions!

The question now is, how to get this thing?

The team moved forward again, and instead of immediately cleaning up the source species on the ground, they first cleaned up the still alive metal mice.

Those metal mice that have not died completely can devour their companions' source species to "resurrect"; and after resurrection, they become even more hideous and terrifying.

Some of the resurrected mice appeared in strange shapes such as double-headed ones, and even attacked themselves crazyly.

Zhang Ping looked at it seriously.

Wang Jun explained: "You cannot devour the same source species, whether it is human or animal. Otherwise, that's it."

Zhang Ping asked: "What if someone secretly gave me the human source species? I can't recognize it."

"No, you can recognize it. You will feel disgusted after seeing it. Moreover, the human species are generally more complicated and easy to identify."

Continue to move forward, the wreckage of five big rats lie on the ground, all of which are bullet holes as big as fists; two are still trembling - they are still alive, they cannot be said to be wreckage, but can only be said to be remnants.

Seeing everyone coming, two big mice suddenly bit each other.

In an instant, a big mouse swallowed the source species of another big mouse; then continued to swallow the source species of three big mice on the ground.

"Roar..." The new metal rat actually roared, no longer a squeak.

A storm of red metal ice crystals hovered, and blades condensed from the circle, and these blades finally condensed on the backs, limbs, etc. of the metal rat.

However, the change did not stop. The new mouse grew two heads; suddenly one of the heads collapsed again and became a metal ice crystal storm, and then condensed in an instant.

What appeared is no longer the head, but a machine gun, almost the same as the team's six-barrel Gatling machine gun.

Seeing this, Zhang Ping was stiff all over.

All the other team members are like this.

The metal mouse roared, and the newly changed "Gatling Machine Gun" began to spin.

Rotate...

Rotate...

Where is the flame? Where is the bullet?

"Haha..." Wang Jun laughed loudly, "Take out the gun and show it our gun."

Suddenly, the three remaining big mice on the scene raised their heads neatly and made squeaks neatly.
Chapter completed!
