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

but.

Although the ultra-titanium alloy ground defense plate and the Devil's Roar Gun have great capabilities and functions!

But looking at their manufacturing materials, their cost is still quite high.

In particular, there is such a high-grade material among the manufacturing materials of the Devil's Roar Rifle!

Lin Yu felt that it was still a bit difficult to make them!

But it doesn't matter.

He immediately opened a trading center!

After defeating this wave of skeletons, the system did not give any hints, indicating that he guessed wrong!

This is not the last wave!

So he has to seize the time to restore the defense system, increase defense and firepower!

They must be completed before the next wave of beasts arrives!

There is nothing wrong with taking precautions first and preparing first!

Who knows if the next wave of beasts will have strange beasts like the black armored beast that burrows into the ground!

The defense of the ground and the preparation of powerful weapons really can't wait any longer!

Chapter 188 Bottom defense system! (3/4)

Simultaneously.

Putting these aside, now there is the most important point!

Cut your losses!

Now the ground-type defense device will be manufactured as soon as possible.

Then manufacture the powerful firearms and weapons as soon as possible.

In this case.

Lin Yu can also reduce losses in the future!

After all, with the defense on the ground, there would be no surprise attacks from strange beasts like the ground-burrowing black armored beast.

Then with powerful firearms, you can quickly kill high-level beasts!

This also prevents the violent impact of high-level alien beasts from destroying their own defense facilities.

So now quickly manufacture the ultra-titanium alloy ground defense shield and the devil's roar rifle.

Not only will it be safer, but it will not only be more calm in the future.

Losses can also be minimized.

After opening the trading center, Lin Yu began to look for the manufacturing materials of the super titanium alloy ground defense shield.

At this moment, he is going to manufacture the ultra-titanium alloy ground defense shield first!

Then go to the manufacture of the Devil's Roar Rifle.

Although the number of materials required for the manufacture of the ultra-titanium alloy ground defense shield is quite large, and the grade is also high, at least there are no too exotic materials.

I have tens of thousands of extremely cold coins to spend every day, and there is basically no problem buying materials.

I'm afraid that the trading center doesn't have it, and I'm not afraid that I can't afford it!

So soon he found all the materials for making [Super Titanium Alloy Ground Defense Shield].

The ultra-titanium alloy ground defense shield is about 1000 meters long and 1000 meters wide!

Lin Yu simply went out and calculated the surrounding area of ​​his shelter.

This range is not limited to the surroundings of the shelter, and the range of various traps around it must be protected.

If you want to defend this large area of ​​ground, you need at least five ultra-titanium alloy ground defense plates!

Five pieces of ultra-titanium alloy ground defense shields will consume a lot of materials!

But he gritted his teeth and decided to make it.

Now, in order to save some materials, what's the point of making only one or two boards?

It would be a big loss if there are high-level alien beasts that penetrate the ground again in the follow-up beast tide!

So such manufacturing is absolutely impossible to save.

Anyway, there are still a lot of materials currently available!

Lin Yu felt that it would not be too traumatic to make a few super titanium alloy ground defense shields.

soon.

All the manufacturing materials for the five ultra-titanium alloy ground defense panels have been frantically traded!

And as he frantically traded various series of massive materials.

Many survivors were shocked!

Because after Lin Yu traded the supplies, there will be reminders from other survivors.

Lin Yu traded your supplies and you got...

this moment.

When Lin Yu made a big deal to trade, many survivors received such reminders frantically.

For this reason, the entire chat channel exploded again!

All the survivors were quite curious, why did Lin Yu spend so much food and extremely cold coins to trade such supplies.

And simply do the math, every survivor knows that Lin Yu's supplies in this wave of transactions will be very massive!

Of course, Lin Yu didn't care how these survivors exclaimed now.

After getting all the materials for making [Super Titanium Alloy Ground Defense Shield].

Lin Yu is now going to manufacture super titanium alloy ground defense shields immediately.

There is a movement in my heart.

People didn't talk too much, and immediately started the manufacture of superalloy ground defense shields.

A moment later.

When all the materials in Lin Yu's warehouse are exhausted.

The five superalloy ground defense panels have all been manufactured!

Now that the ultra-titanium alloy ground defense shield has been manufactured.

Then he is going to install the ultra-titanium alloy ground defense shield immediately!

The overall installation of the superalloy ground defense shield is quite simple.

Just choose a good location and move your mind!

The use of large equipment in the extremely cold world is quite conscientious.

Quickly, it didn't take long.

Lin Yu began to install the super titanium alloy ground defense plates piece by piece.

Soon.

All the ultra-titanium alloy ground defense panels were installed around the shelter by Lin Yu.

The entire ground is covered with ultra-titanium alloy ground defense shields!

The entire ultra-titanium alloy ground defense shield is golden in color, exuding a steel luster, and it is very strong at first glance!

He took out the explosive grenade gun and fired a few shots directly at the defensive shield.

next second.

Only a "ding" came out.

The grenade was immediately bounced off by the defensive shield!

Look at the hit position, there is really no white trace left.

It is conceivable that this ultra-titanium alloy ground defense plate is really very, very strong!

The superalloy ground defense plate's overall solid ability and defense ability are really invincible.

Not bad!

After clapping his hands, Lin Yu retracted the explosive grenade gun, and his mood instantly improved.

The entire ground has been covered with super titanium alloy ground defense shields, and Lin Yu feels full of security!

Now with the protection of the super titanium alloy ground defense shield, Lin Yu no longer has to worry about the ground defense.

Afterwards, no matter when the beast horde strikes or other normal times, it will be fine.

It would be completely impossible for these strange beasts to attack themselves by burrowing into the ground!

There is a perfect defense around the ground.

The words below the ground also have a perfect defense.

Then he felt that he was short of an air defense!

However, Lin Yu was not worried about the air defense with a snowy sky.

She planned to wait until all the artificial intelligence devices of the large-scale snow buggy were manufactured before proceeding with the manufacturing of this snowstorm.

Don't worry, take your time.

The ancients said that you can't eat hot tofu in a hurry!

PS: Today is a day of daily life, please support me with a small gift!

Chapter 189 The Eve! (4/4)

soon.

After the ultra-titanium alloy ground defense shield is manufactured and installed.

Lin Yu opened the trading center again.

The superalloy ground defense shield has been successfully manufactured and installed.

The next step is to manufacture the Devil's Roar Rifle!

【恶魔之吼步枪：纤维金属X50、高级金属X50、特级钢板X50、高级弹簧X1、特制塑料X1】

It's okay too.

Lin Yu thought it was easy to collect the manufacturing materials for the Devil's Roar Rifle.

Also not too difficult.

He quickly found most of the crafting materials.

But now there is only one material Lin Yu searched the entire trading center and couldn't find it!

Premium Springs!

There is really not a single survivor in the entire trading center for this material to put it on the shelves.

Not too much.

In fact, I have already thought of it.

After all, advanced springs carry the word "advanced"!

Relying on Lin Yu's cognition, it is very difficult to find materials with the word "advanced" almost!

Lin Yu thinks that such materials are probably the top materials in the extremely cold world.

Shrugging, Lin Yu smiled.

No complaints about the requirements for the manufacturing materials of the Devil's Roar Rifle is very strange.
