Survival in extreme cold: I have 9000 trillion extreme cold coins!

As the manufacturing material of the SS-level weapon Devil's Roar Rifle, it is understandable that it is strange.

Lucky in misfortune!

Lin Yu felt that the Devil's Roar Rifle only needed high-grade springs.

If the Devil's Roar Rifle requires high-grade manufacturing materials.

Then it is estimated that in a short time, I am afraid that I really can't make the Devil's Roar rifle.

soon.

After Lin Yu saw that he really couldn't find high-grade springs in the trading center.

He directly opened the survival point store!

According to his understanding, the advanced material survival point store is quite complete!

If this high-grade spring is available, the price is still cheap.

He is ready to trade two.

Bu Lin Yu, the roar of the devil, definitely wants to make more.

After all, the Devil's Roar Rifle only has three bullets if it encounters a particularly powerful beast or enemy.

He estimated that the enemy on the opposite side would definitely not give him time to change bullets!

Therefore, you can prepare a few more and put them in the system warehouse.

In this way, it doesn't matter even if Lin Yu doesn't need to change the bullets.

After the three bullets are finished, it will be thrown away first, and then the second devil's roar step will be taken from the warehouse and so on.

Ha ha.

In such a simple and rude way.

Lin Yu felt that he might still use it in the future.

That's why the Devil's Roar Rifle is a firepower weapon with great damage and few bullets.

If you have capital, you still need to make two more!

Gee!

There really is!

After opening the Survival Points store, I quickly found the material of high-grade springs.

【Advanced Spring】

[Twenty Survival Points]

Forehead...

so far so good!

This high-grade spring is not as expensive as imagined.

On the contrary, for Lin Yu, the price of high-grade springs is still very cheap.

So he directly exchanged for three in one go!

The Devil's Roar Rifle Today Lin Yu plans to make three first.

The overall cost of the Devil's Roar Rifle is not too cheap.

No matter how many quantities Lin Yu is planning, he should wait until he is richer to continue manufacturing.

soon.

After all the three high-level springs have been traded.

He began to rapidly manufacture the Devil's Roar Rifle.

in a blink.

Shine!

The Devil's Roar Rifle is finished!

Look at the three Devil's Roar rifles that appear in front of you.

Lin Yu held one of them in his hand.

After taking a closer look, Lin Yu felt that the shape of the Devil's Roar Rifle was quite unique.

The whole feeling is a bit similar to the kind of laser square weapon used by aliens.

And the caliber of the Devil's Roar rifle is also very large, probably the size of a fist!

Anyway, as long as you are not a fool, you can see that the Devil's Roar Gun is extraordinary.

Especially the painting of the Devil's Roar rifle is also very handsome!

The whole body is painted in silver with green stripes embellished on it.

The overall appearance is really good!

After briefly admiring the Devil's Roar Rifle, Lin Yu didn't think about it anymore.

Now he's not going to test the Devil's Roar rifle.

He plans to save the test of the Devil's Roar Rifle for the next beast tide.

After all, the bullets of the Devil's Roar rifle are quite precious, and he doesn't want to waste them meaninglessly!

Lin Yu is going to make more bullets for the Devil's Roar Rifle.

The number of bullets for the Devil's Roar rifle is really too small!

If you want to maintain the damage and battery life of the Devil's Roar Rifle, then the bullet is definitely indispensable.

After quickly flipping through dozens of pages, he quickly found the bullet manufacturing method for the Devil's Roar rifle.

Forehead...

Compared with the bullets of other firearms, the bullets of this Devil's Roar rifle are slightly more expensive.

But now that the Devil's Roar rifles have been manufactured.

Although this bullet is a little expensive, Lin Yu also produced about a hundred of them.

It was really bleeding!

At this moment, Lin Yu really exclaimed, fortunately, he had killed a few strange beasts and obtained a lot of supplies.

Otherwise, the manufacture of the Devil's Roar Rifle and the superalloy ground defense shield may have to wait for a long time.

soon.

Time passed by every minute and every second.

After the production of the super-titanium alloy ground defense plate Devil's Roar Rifle has been completed.

Lin Yu didn t rest at all now.

Instead, move on to the next thing without stopping.

This matter is also very important!

That is what Lin Yu is going to do next.

Prepare your own battlefield defenses, and re-arrange high-explosive landmine traps and incendiary bomb traps!

Because of the impact of that wave of skeleton army just now.

All the traps set by Lin Yu were used!

So Lin Yu immediately made a lot of high-explosive landmines and incendiary bombs with this effort.

At the same time, he also created a lot of venom spikes and spikes.

After the impact of the last wave of skeleton army.

Lin Yu decided to upgrade his trap defense again!

Several waves of high-level beast hordes and a huge number of beast hordes made Lin Yu realize the importance of traps.

If there are no poison spike traps, high mine incendiary traps, etc. in front of the fence.

Lin Yu reckoned that he would have gone to the cold for hundreds of times!

Of course, now Lin Yu has also seen the shortcomings of these traps through these waves of beast tides.

So it's up to you to decide to upgrade them all!

Venom stings that had only one row are now two rows.

There was only one row of spiked guardrails, and now there are two rows at the front and back.

Then the number of high-explosive mine traps and incendiary bomb traps is about twice as large as before!

At the same time, their coverage area has roughly tripled.

No matter how many such traps have been upgraded, Lin Yu, the animal tide, feels that there is no need to be afraid!

With such a powerful trap ahead to hold back the tide of beasts.

Those strange beasts probably couldn't even touch the edge of the wall!

two hours later.

Lin Yu completed a series of traps.

Then they took Ah Huang and they placed all of them and buried them.

Looking around, he looked at all the defense facilities he had prepared.

Lin Yu's hanging heart slowly let go.

With this kind of defense, it will be very simple to resist and kill the beast hordes afterwards.

This will take advantage of the arrival of the new wave of beasts.

He took A Huang Meiniang to eat a little more food.

Resisting the beast swarm still takes a lot of energy, and it is necessary to eat some food to supplement it.

Simultaneously.

Lin Yu, who wanted to become stronger, wanted to eat more!

Strength meat, agility meat, spirit meat, hard stone meat, Lin Yu can't be wasted.

After simply eating some of these meat pieces, Lin Yu became much stronger!

In terms of strength, agility and defense, Lin Yu has been sublimated again!

After sitting at the dining table and eating and drinking, I feel the great changes in myself again.

Night slowly began to fall.

After Lin Yu went out to collect some supplies, he now had some dinner.

Lin Yu looked at his watch after eating and drinking.

It is estimated that one more day tomorrow will almost end the catastrophe day!

Chapter 190 The Last Wave! (Thanks for the gift plus more!)

Lin Yu climbed up the wall and looked around.

The cold wind was blowing, and there was no sound in the silent night, so quiet and terrifying!

The open area in front of it is now where there is really no shadow of a strange beast.

But at this moment Lin Yu did not show any happy look.

On the contrary, after seeing such a situation now, his expression gradually became worried.

Lin Yu didn't believe that the extremely cold world would be so conscientious.

There was no beast tide tonight.

This is not like the style of the extremely cold world.
