The end of the world: Start with a gun and build a tank in ten days

This time, however, it was not so lucky.

The moment it rushed in, it was affected by the explosion, and the price this time was a complete hind leg.

It hesitated for a while, raised its head, and happened to see the man above. The barrel of the gun in his arms was already hot and red, his clothes were burned off, and his hands were blistered from the heat.

Even so, he still did not dare to throw away the weapon in his hand.

And he placed all his hopes of life on it.

Thinking of this, the little spider rushed in again. This time, it completely turned into a cold machine.

The built-in system helps it calculate the safety factor at every step, and this has become its only reliance.

The explosion was either in the distance, in front of you, or under your feet.

But that didn't stop it from completing its mission.

Finally, at the cost of three legs and one hand, the little spider successfully collected five evolution crystals.

Although it was just a reconnaissance robot, it lived up to Lin Nan's expectations.

The collection task was completed and without stopping, it climbed up like crazy on its only three remaining legs.

And its actions were eventually discovered by the giant bird behind it.

At first, this little thing, which was no bigger than its own eyeballs, did not attract its attention, but when it saw that it kept diving into the explosion zone without fear even if it was covered with bruises, the giant bird noticed something was wrong.

Especially when he saw it put the evolution crystal into his small bag, this completely caught the giant bird's attention.

It wants to steal the evolution crystal!

Upon realizing that he had been discovered, the little spider instantly emitted a burst of smoke, and then stopped.

In this way, it can blend into the surrounding environment, and no matter how powerful the giant bird's eyesight is, it will not be able to detect it.

And this is indeed the case.

Just after the smoke dissipated, the little spider in front of him disappeared.

However, it probably took a few seconds.

The giant bird suddenly moved and picked up the little spider in its mouth.

It turns out that the explosion destroyed the little spider's hiding function.

After a short circuit, the skin on the little spider's body returned to its original appearance.

At this moment, Lin Nan's ears suddenly heard the sound of the system,

"Reconnaissance robot spider, please fire metal silk!

20 points are required! "

Only then did Lin Nan realize that the little spider had been caught in the giant bird's mouth.

He knew it was all over,

The last hope was shattered!

"Warning, reconnaissance robot spider, please fire metal silk!

20 points are required! "

The system sound sounded again,

"Did Spider-Man ask for it?"

Lin Nan smiled, his smile a little sad.

"Your spider silk can control a creature as big as an adult. How can you control such a big monster!"

That's what he said, but in the end, Lin Nan agreed.

This is the last stubbornness of the little spider, so why not his last stubbornness as a human being!

At this time, the little spider who received Lin Nan's authorization flashed red light all over his body, and the beeping sound made the mutant crow feel something abnormal.

The creature's innate instinct tells it not to bite.

However, it wouldn't bite and wouldn't let go.

"Buzz buzz-"

The little spider looked at Lin Nan and Chu Mengyao, with two small red eyes flashing.

Seeing that its limbs were mutilated and its body was broken, Chu Mengyao couldn't help but wipe her tears.

"Buzz buzz-"

"Buzz buzz-"

"Buzz buzz-"

This cold mechanical spider waved its cracked front claws as if saying its final farewell to them.

Then, there was a brief silence, and the little spider lowered his arm.

Then a dazzling red light suddenly flashed.

at last,

"Bang"

With a sound, the little spider exploded!

Small body, but huge energy.

This explosion directly blew the giant bird's beak and frightened it into flying instantly.

Then there was the constant whining.

Lin Nan was still thinking, wasn't he going to shoot spider silk? Why did he self-destruct?

As soon as this idea came to his mind, he saw a string of spider silk flying from the original direction, aiming directly at his location.

To be precise, it was on the wall next to him.

In the middle of the spider web, there was a small black bag hanging.

"There are five evolution crystals!"

Chu Mengyao took the small bag and found the crystal inside, then handed it directly to Lin Nan.

Lin Nan took it with a hand full of blisters.

"Little guy, I didn't expect you to actually do it!"

Then Lin Nan said in a particularly firm tone,

“Second level!

System, I want to upgrade to the second level! "

The system may not be able to stand it anymore. As soon as Lin Nan finished speaking, a green light surrounded Lin Nan's body.

In an instant, his injuries were healed, the heated barrel was cooled, and all negative conditions were cleared.

Even Chu Mengyao has returned to her peak condition.

Lin Nan wouldn't be satisfied if it was just these.

Just then the system sound sounded again,

"Ding, congratulations to the host for successfully promoting this system to the second level.

All products in the system have a 10% discount, and all first-level skill costs have a 10% discount.

The host will also be rewarded with one thousand points.

In addition, the host will be rewarded with a first-level secret realm exploration ticket × 1

In addition, the host will be rewarded with a high-tech upgrade module - Slaver x 1. "

"One discount?"

"Hold the grass!"

Lin Nan couldn't believe what the system said, but after releasing the skill, only 2 points were deducted.

You must know that it actually costs 20 points to blast and carry out a funeral.

Originally, he was worried that he would not have enough kill points and would be unable to connect with his skills. Now, Lin Nan not only used them casually, but the more he used them, the more points he accumulated.

In addition, the weapons in the system store are really discounted.

The 400-point giant Gatling really only costs 40 points now.

Just when Lin Nan was thinking about how to make a comeback, Chu Mengyao suddenly said,

"Brother Nan, I have recovered and I can help you control the zombies!"

Hearing this voice, Lin Nan felt happy.

"How much can you control?"

"If it's stable, 10!"

“10?!

so much? ? ? "

After hearing her words, Lin Nan immediately threw down 10 giant Gatlings.

The price that once paid for one can now buy ten!

"Control them to get guns. If we don't kill all the zombies in the street today, my surname will not be Lin!"

Lin Nan roared loudly, with the momentum of one man being in charge and ten thousand men unable to stop him.

Chu Mengyao was even more confused by the neatly arranged ten giant Gatlings below.

But she soon came to her senses and followed Lin Nan's instructions to try to control it.

The second-level mutated crow was hovering in the sky. The explosion just now really shocked it, but it quickly returned to normal.

Seeing more and more zombies pouring in, it screamed a lot.

However, just as it swooped down, trying to sneak attack Lin Nan and try to scare him,

Suddenly a series of bullets quickly hit it.

But he was dodged by his amazing speed.

But, this is not over yet.

I saw another series of bullets coming towards him, but unfortunately they missed again.

It hovered excitedly, as if in demonstration.

But as it was flying, it suddenly felt something was wrong. It saw that the zombies had given up climbing the stairs and turned to kill to the side.

At some point, a total of ten "people" holding giant Gatlings appeared, five on each side.

And once these "people" are eliminated, new "people" will take over the weapons and continue to control Gatlin, in an endless stream.

And the two people upstairs,

Where are the two people upstairs?

The second-level mutated crow was surprised to find that the two people before him were gone, replaced by a black hole.

It flew to the side and discovered that it turned out to be a huge cylindrical tube.

But, wherever it flies, where does the hole point?

Just like those female crows who pursue it and bore it!

"Control it, just for a second!"

"three,"

"two,"

"one,"

"emission!"

Lin Nan's voice suddenly sounded, and as the words fell, something suddenly appeared in the black hole.

The second-level mutated crow was very confused about what was running towards him, but his intuition told it to get away quickly.

but,

It's too late,

It couldn't move.

"Bang!"

It felt like a pain.

But at the same time, it can also move the body.

It looked at itself and saw the blue sky after the rain.

And that familiar tall building!

Suddenly, a voice came, it was Lin Nan.

He was holding a trumpet he got from nowhere, pointing at its body and shouting,

"Comrade, you have no heart anymore. According to the settings, you are already dead, do you understand?"

The crow looked down at its body again, and then it realized that a big hole had appeared in its body.

The so-called sky and tall buildings can all be seen through this hole.

At this time, it raised its head again, and the anger on its face disappeared, revealing a humane and thoughtful face.

It seemed to be wondering what Lin Nan's words meant.

He also seems to be thinking about why that thing can blast out a tall building and a sky from his body.

Just thinking about it made him sleepy!

Then, with a "bang", it fell to the ground.

This scene all fell in Chu Mengyao's eyes. She sat on the Tiger tank that Lin Nan exchanged for 400 points and looked at Lin Nan in shock.

"Why did it fall?

Did you really say that? "

Lin Nan smiled and said,

"No, I just reminded him that he can't live without a heart!"

In fact, he originally aimed at its head, and because of the first operation, he hit the heart.

Not bad though!

After listening to Lin Nan's words, Chu Mengyao said thoughtfully,

"But, it has mutated, can it still function as normal?"

After thinking about it, Lin Nan felt that what she said made sense.

"How many more shots shall we have?"

"Bang——"

"Bang——"

"Bang——"

Three more cannonballs were fired, and the second-level mutated crow was beaten to pieces!

This time, it is really dead!

"Ding, congratulations to the host for killing the second-level mutated crow for the first time!

Reward 100 kill points! "

The sound of system rewards sounded in his ears again. Lin Nan just wanted to be happy when he saw Chu Mengyao's face looked sad.

"It's a pity that the little spider died just once!"

Chu Mengyao sighed slightly.

If it hadn't been for risking his life to collect 5 evolution crystals and upgrade Lin Nan's system to the second level, I'm afraid they would have died on the spot.

Just looking at Chu Mengyao's sad expression, Lin Nan laughed.

Chu Mengyao looked at Lin Nan with some confusion. Unexpectedly, the latter stretched out his hand, and a small chip suddenly appeared in his hand.

"This is……"

Before the little girl finished speaking, a bright light suddenly flashed,

Just hear a buzz...
