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

It is really not easy to get a small assault speedboat!

"Huh~ Not bad not bad!"

Time is fast.

Following Lin Yu's simple inventory, he checked his harvest today.

Lin Yu let out a long breath.

The smile on the face of the whole person is really getting bigger and bigger!

At the same time, since the materials are counted, there is no problem.

Then Lin Yu can do it, and proceed to the next thing!

Although it is midnight, Lin Yu still wants to do this first!

Although it is getting late, it is time to rest.

But here for Lin Yu, he didn t choose to rest first.

Lin Yu was going to finish this matter first, and then go to rest.

If this matter is not finished, Lin Yu is really afraid that he will not be able to sleep.

What Lin Yu was going to do.Nothing too complicated either.

What Lin Yu wants to do is exactly:

Upgrade the Thunder Dusk Submachine Gun!

Strengthen the Thunder Dusk submachine gun!

Chapter 719 Big Upgrade

To upgrade the level of the Thunder Dusk submachine gun, strengthen the ability of the Thunder Dusk submachine gun!

What Lin Yu is going to do is the above!

The Thunder Dusk submachine gun is an SSS-level ceiling fire weapon, and its upgrade and strengthening is a must.

Especially the positioning of the Thunder Dusk submachine gun is currently what Lin Yu needs very much.

At the same time, the overall ability of this Thunder Dusk submachine gun is quite, quite excellent.

So in this situation, now Lin Yu must strengthen and upgrade the Thunder Dusk submachine gun if he is here!

In addition, the defense-breaking beast sniper rifle, the Blizzard Purgatory sniper rifle, and the ultimate level of violent Gatling have all been strengthened and upgraded.

For this Thunder Dusk submachine gun, how could Lin Yu choose not to strengthen and upgrade?

Such a thing does not exist at all.

Thinking of Lin Yu, he decided here.

To strengthen and upgrade the Thunder Dusk submachine gun.

Lin Yu didn't talk nonsense!

This will work.

Lin Yu first took out the weapon upgrade scroll!

This weapon upgrade volume is for upgrading the Thunder Dusk submachine gun!

The original anti-defense beast sniper rifle, the Blizzard purgatory sniper rifle, and the ultimate level of violent Gatling.

It is the use of weapon upgrades to upgrade the level!

If this weapon is upgraded, the overall ability is still terrifying!

After use, you can upgrade the corresponding weapon, which will make the weapon more powerful!

Then after using the weapon upgrade roll.

The weapon upgrade roll will also increase the power, defense ability, and penetration ability of the weapon!

But the only thing is that the amount of increased weapon power, defense ability, and penetration ability are all random!

But Lin Yu doesn't care about these details.

The main reason is that this weapon upgrade volume can directly raise the weapon to a large level attribute.

Then this kind of ability is the weapon upgrade volume that is really invincible!

After thinking that Lin Yu took out the weapon upgrade roll.

Lin Yu immediately used it on the Thunder Dusk submachine gun!

[Survivor Lin Yu, do you want to consume (weapon upgrade volume X1) to upgrade your weapon (Thunder Dusk submachine gun)? 】

After Lin Yu gave the weapon upgrade volume to the Thunder Dusk submachine gun here.

A light screen has appeared in front of his eyes.

Looking at this light screen, Lin Yu smiled and replied, "Yes! I'm going to consume the weapon upgrade roll to upgrade the Thunder Dusk submachine gun!"

[Congratulations to your survivor Lin Yu, you have successfully consumed the weapon upgrade volume! 】

[Congratulations to you survivor Lin Yu, your Thunder Dusk submachine gun has been upgraded!Current SSSS grade! 】

[Congratulations to you, Lin Yu, the survivor, your Thunder Yellow cum submachine gun has doubled its power bonus because of the use of the weapon upgrade roll! 1

[Congratulations to you, Lin Yu, the survivor, your Thunder Dusk submachine gun has increased its defense ability by 15 times because of the use of the weapon upgrade scroll! 】

[Congratulations to Lin Yu, the survivor, your Thunder Dusk submachine gun has doubled the penetration ability bonus because of the use of the weapon upgrade roll! 】

Not bad!

The current upgrade of the Thunder Dusk submachine gun is still very powerful overall!

With the use of the weapon upgrade volume, the Thunder Dusk submachine gun has not only been successfully upgraded to the SSSS level.

And this Thunder Dusk submachine gun, its power has also doubled!

The defense ability has increased by [-] times!

Penetration power doubled!

Good guy!

Today's wave of weapon upgrade rolls is used, which is really a surprise to Lin Yu!

And now with the Thunder Dusk submachine gun, after successfully upgrading to the SSSS level.

Then you can see the Thunder Dusk submachine gun here.

It behaves the same as the Anti-Defense Beast Sniper Rifle, Blizzard Purgatory Sniper Rifle, and Ultimate Rage Gatling!

At this moment, the Thunder Dusk submachine gun has also begun to change its overall shape!

It can be seen that the Thunder Dusk submachine gun as a whole seems to have become smaller!

However, although the Thunder Dusk submachine gun is a little smaller, it is also more detailed!

Especially around the submachine gun in the entire Thunder Dusk, the beating Thunder couldn't help but become more blue!

Then the thunder that danced around the Thunder Dusk submachine gun, they couldn't help becoming more violent!

Even at this moment after Lin Yu held the Thunder Dusk submachine gun in his hand, he couldn't help hearing the sound of thunder beating!

This Thunder Dusk submachine gun is simply quite metaphysical.

But at present, the shape change of the Thunder Dusk submachine gun is very cool and handsome.

At this moment, the Thunder Dusk submachine gun is much cooler and more handsome than the original one!

Holding the Thunder Dusk submachine gun in his hand, Lin Yu really couldn't put it down!

Lin Yu nodded at this moment.

I am really satisfied with the upgrade of the Thunder Dusk submachine gun!

And now Lin Yu knows.

As the Thunder Dusk submachine gun has been upgraded to the SSSS level, its power penetration has been simultaneously strengthened.

Lin Yu knew that the overall combat power of this Thunder Dusk submachine gun had increased a lot.

Unconsciously.

Lin Yu is really looking forward to it!

Quite looking forward to the power of this Thunder Dusk submachine gun!

But what is the power of the Thunder Dusk submachine gun at present, Lin Yu did not overdo it.

This will work.

After the upgrade of the Thunder Dusk submachine gun is completed, what Lin Yu is going to do is not over yet!

Looking at the Thunder Dusk submachine gun in his hand, Lin Yu smiled at the moment.

Since this Thunder Dusk submachine gun has been successfully upgraded to the SSSS level.

So Lin Yu is here, he is ready to start strengthening the Thunder Dusk submachine gun!

The high-level solid obsidian, high-level rock cracking stone, and high-level smelting stone were all taken out.

Look at this high-level attribute stone.

Lin Yu really secretly exclaimed that fortunately, he left a lot of foresight at the time!

Otherwise, at this moment, the Thunder Haze Twilight submachine gun may be difficult to strengthen!

High-grade solid obsidian, it mainly increases the defense ability of weapons.

This Lin Yu is going to use ten for the Thunder Dusk submachine gun!

It's the same as the anti-defense beast sniper rifle, Blizzard purgatory shotgun, and the ultimate level of violent Gatling.

Thunder Dusk submachine gun is the only one!

Therefore, Lin Yu must pay great attention to the defensive ability of the Thunder Dusk submachine gun!

Lin Yu didn't want the Thunder Dusk submachine gun that had spent so much effort to be destroyed!

Then advanced rock cracking stone, it can increase the power of weapons.

So Lin Yu is also going to use ten here.

The Thunder Dusk submachine gun is currently used as a firepower weapon, and its power must be as powerful as possible!

Although the power of the Thunder Dusk submachine gun is already very, very huge.

But Lin Yu felt that it would be better if the Ting Dusk submachine gun could be bigger!

As a fire weapon, Lin Yu is still afraid of the great power of the Thunder Yellow and submachine gun?

Lin Yu longed for the Thunder Dusk submachine gun, its power would become more and more terrifying!

So for this Thunder Dusk submachine gun, Lin Yu must join ten high-level rock crackers!

As for the advanced smelting stone, its current main ability is to increase the burning ability of weapon bullets!

Talking about this advanced smelting stone from the side, it also increases the power of weapons!

So Lin Yu will definitely use this advanced smelting stone a lot!

OK!

That's pretty much it.

The enhancement of the Thunder Dusk submachine gun currently consumes ten high-level solid obsidian, ten high-level rock cracking stones, and ten high-level smelting stones!

At present, as long as they are successful, they are all used for the Thunder Dusk submachine gun.

My Thunder Dusk submachine gun will usher in a new transformation again!

Thinking of Lin Yu, I can't wait, and I am ready to use them for the Thunder Dusk submachine gun!

of course.

Although there are still many high-grade charcoal cracking stones, high-grade smelting stones, and high-grade solid obsidian Lin Yu.

But Lin Yu didn't really use the Thunder Dusk submachine gun too much!
