Global Wasteland: I Unboxed Top Vaults

Chapter 317 Upgrade, upgrade!Get powerful combat weapons!

The more Lin thought about it, the more he felt it was possible.

Even if the bazooka can't be mass-produced for a while, he can still equip the robot dogs with the MP5 submachine gun.

The power supply problem that plagued the robot dog is actually easy to solve.

Make more robot dogs that can be charged with solar panels, and then let them be fully charged, even if the lizardmen come all night, there is no need to worry at all!

Lin Yue walked quickly to the refuge, opened the alloy door, and brought his companions back to the safe and comfortable refuge.

Turning on the light, Lin Yue walked into the shelter bathed in a warm light.

After the tension from the previous battle faded away, a deep sense of exhaustion gradually came.

Even so, he didn't want to just go to sleep.

The things to be done are not finished yet, especially, this time he collected a lot of saltpeter, which stimulated his nerves and curiosity, and made him want to get out black powder, which can be said to be the most important thing nowadays.

Think about it, if you combine black powder and crossbow bolts, what will be produced?
Explosive arrows!
A weapon more terrifying and powerful than burning arrows!

If equipped on a ballista...

Even if a giant creature comes, it can be unimaginably injured by a simple attack of an explosive ballista arrow!

Before that, though, he needs a safe and secure environment.

In case of accidental explosion, he will not harm himself and the shelter.

Xiaobai and Xiaomeng led the little ice lizard to the bathroom to wash off the blood and sweat of the lizard man. Lin Yue also took off his night suit and immediately went to wash it off.

I have to say, the taste is too bad.

After cleaning, he gave Xiaobai and the others something to eat. Lin Yue also took a piece of lion-headed bear steak in his mouth, went down to the basement, and walked to one of the emergency passages.

Halfway through the passage, he pushed open a metal door that hadn't been opened for a long time, and entered it.

Turning on the light, Lin Yue looked at the room made of alloys, and took out a high-precision research workbench in front of him.

Alloy refuge, currently, among all his refuges, it is the only one that is the safest and strongest.

At least when hiding here, it is estimated that except for thunderstorms, any other disasters will not be able to break through here and have any impact on him.

It can be said that it is extremely strong, and it is the most suitable refuge for the last humans in this different world.

The space of [-] square meters is also spacious enough.

Lin Yue opened the door ajar, and at the position he is standing now, in case of any accident, he can rush out of the refuge door as quickly as possible.

I took out 1 unit of natural sulfur ore and put it on the workbench, and the workbench decomposed it into sulfur ore and other things.

This is quite convenient.

Lin Yue took out a piece of paper, put the sulfur ore on it, and put other impurities into the storage space
He spent 300 points in the Survival Point Mall in exchange for 3 units of charcoal, which he also put on the piece of paper, and he got the sulfur ore.

"I remember, it seems that the ratio said 2 units of saltpeter?" Lin Yue recalled the knowledge he had read on the Internet before, and after placing 2 units of saltpeter on top, the system suddenly made a sound.

[You have obtained the black powder design! 】

Good guy, how did it go so smoothly this time?

Lin Yue even touched the alloy door with his hands, and his feet stepped halfway out.

To be honest, he really only knows the so-called 1 sulfur, 2 nitrate, and 3 charcoal in terms of explosions and gunpowder. The rest is to go to the street when I was a child to pick up the ones that were not successfully blown up when people got married and set off firecrackers, and then poured out the inside. Gunpowder, finally lit with a match.

But being able to successfully get out the black powder is worth celebrating.

"Black gunpowder... how powerful is this thing?" Lin Yue started to make it immediately, and after preparing the materials required for the design, a white light flashed, and five units of black powder produced successfully appeared in front of his eyes.

According to the requirements of the design drawing, there is also a piece of paper, and this paper is also the outer packaging for the black gunpowder.

Lin Yue picked up one of the bags and immediately appraised it.

[Primary black powder: it can burn violently after being ignited, and at the same time, the volume will expand rapidly, the pressure will increase violently, and the large amount of heat released by the reaction will further increase the temperature sharply to above 1000 degrees Celsius, causing the gas to expand and produce a strong explosion. The thrust resulted in an explosion.During an explosion, particles of solid products are dispersed in the gas, producing a large amount of smoke. 】

The power does not seem to be great.

After all, to be honest, this thing is more used for fireworks and firecrackers. If you want to increase its power, you have to add some additional materials.

material, must be harmful.

Just like...

Lin Yue took out a piece of steel and put it on a unit of black powder, but there was no response.

Another experiment was put on three units of black powder, and the system's judgment came.

[Upgrading black powder to steel ball explosives requires a universal upgrade plan X1]

really.

Although I don't know if there is such a so-called steel ball explosive in reality, since the system has determined that it is possible, then there is no problem.

I glanced at the rest of the universal upgrade blueprints, and they were out of stock.

By the way, he listed [-] bottles of wine on the World Trading Channel, and chose to collect a wave directly, the more the better.

[You got steel ball explosives! 】

The volume of the black powder in front of him has slightly become about twice as large.

Lin Yue didn't stop.

[You disassembled the steel ball explosives and obtained the design drawing of the steel ball explosives! 】

This time it works.

[Steel Ball Explosives: Black Powder X3, Steel X1]

Putting away the remaining black powder on the table, Lin Yue immediately chose to make it!
【You got Steel Ball Dynamite X2】

What appeared in front of him was exactly the same thing as before.

[Steel Ball Explosives: After a sufficient amount of black powder explodes, the steel balls in the explosives will be ejected to cause great damage, with a killing radius of three meters! 】

Lin Yue looked at the exciting text identified by the system, and couldn't help nodding slightly.

If this thing is shot with a ballista arrow, what effect will it have?
At least when faced with the impact of a group of lizardman legions, it is estimated that it will cause great damage and shock them greatly!

Under the circumstances that TNT or C4 cannot be obtained or manufactured, this thing should be the most powerful weapon in his possession at present.

Lin Yue's heart was full of excitement!

He took out the ballista and placed it in front of him, and then put a steel ball explosive on the ballista arrow.

[Upgrade the ballista arrows to explosive ballista arrows, you need a universal upgrade design X1]

Judgment succeeded!

So……

[You lost 3 bottles of wine, and got the universal upgrade design X11! 】

After the mall evolved into a world trading mall, the quotations were received much faster, and he immediately selected and successfully traded the one with the highest bid.

Others take your time, don't worry.

Next...

upgrade! !
[You got the Explosive Ballista Arrow! 】
