Global Cataclysm: My doomsday fortress can be infinitely upgraded

[Level 2

Red Pill] Upgrade Direction: Level 3 Red Pill

Branch ↓

Treatment Effect (2000/800 Drug Supply): Injury recovery effect increased from 70% to 85%.

Time (4000/1500 Dose): Buff increased from 5 days to 7 days.

Self-Circulating Cleanse (10,000/5,000 doses): After use, it also creates beneficial clotting cells in the body, continuously filters harmful impurities from the body for 7 days, and reduces your need for food and sleep by 40%.

"It's so fierce!What kind of self-circulation cleaning is

this!""You can save

food after eating!" Qin Jian couldn't help but complain, but he felt that this was not good, after all, he still had to enjoy food all day long! One meal a day was uncomfortable, not to mention that it had an impact on the quality of sleep!

Moreover, it was really expensive, 10,000 points, didn't this rob money?

Qin Jian felt that he would have tens of thousands of points on hand in the future, and he would not casually upgrade the third option, after all, the purpose of that option should be used to deal with emergencies.

Only when you have no food, no shelter, and are in danger that you meet these three conditions will you achieve the best results......

The upgraded red pill had the effect of removing the disease, and Qin Jian was also relieved, and he didn't plan to check the upgrade options of other medicines.

Then, Qin Jian thought that he had to upgrade the barbed wire yesterday, so he immediately checked it.

[Barbed Wire Fence]

Upgrade Direction: Wire Fence

Wall Branch ↓

Towering (800): Increase the height of the barbed wire fence to 5 meters.

Fire Resistance (500): Fire damage from any path is reduced by 50% Cold Resistance (500):

Do not freeze, increase the service life.

Today, there are three upgrade options left for Barbed Wire.

Qin Jian thought about it for a while and decided to upgrade them all!

If the greenhouse is still not in a hurry to upgrade, when there are seeds, when it is just to upgrade.

With a wave of his hand, 1800 points were directly deducted, leaving 1703 points.

"Bump!"

The next moment, there was a loud noise from the barbed wire fence outside the house, and Qin Jian shrank back in fright.

When I walked out, the barbed wire fence suddenly changed drastically from before.

The first thing that catches the eye is the height of the barbed wire, and after upgrading the "towering", it gives people a feeling of airtightness and unventilation as a whole.

This time, let alone climbing over, it is impossible to even build two ladders!

Because the scope of the anti-theft net has also become larger, from the top of the barbed wire fence to the front of the extension.

Just because of this part of the extension, I am afraid that it will dissuade anyone who wants to invade

, because if you climb to a certain height, your head will inevitably hit the security net.

Anti-theft nets and barbed wire are all in one, and anyone who knows a little bit about this barbed wire knows what the consequences of hitting ...... are

Coupled with the upgraded barbed wire to resist fire and cold, if you look closely, the entire barbed wire fence is sparkling, as if it has been oiled

! Qin Jian felt that even if a plane collided with it now, it would be impossible to break through the barbed wire

! "Well, it's too safe! I can't find a sense of crisis at all!" Qin

Jian sighed with his waist in his hand, and his face seemed to be full of the word "awesome".

The barbed wire fence was upgraded to a steel wire fence, and Qin Jian naturally wanted to check out the new upgrade options as well.

[Wire Mesh Wall]

Upgrade Direction: Rock Wall

Branch ↓

Material (2000): Replace the original steel wire mesh material to generate a harder stone wall.

Height (5000): Increases the wall height to 10 meters.

Earthquake Resistance (3500): The foundation of the wall is deeper, which effectively resists the shock wave of the earthquake.

Lighting (2000): Place lighting fixtures around the walls to make it easier to see what's going on outside the walls at night.

Sentry (6000): A patrol sentry is placed on the wall to facilitate patrolling at night.

"Oh my God, if this is all upgraded, my shelter will really become a fortress!"

After seeing these amazing upgrade options, Qin Jian gasped and was very amazed.

Changing the barbed wire fence into a stone wall and upgrading the height is safer, but it is also more conspicuous.

Maybe how many survivors will run under the wall to ask for help in the future!And

he will definitely stand on the wall at that time, looking down at everyone arrogantly, and then reply in unison: "Get out

!" "Thank you, it's cool!"

Qin Jian thought for a long time, smiled and said to himself, full of expectations for the future.

The upgrade isn't done yet.

Qin Jian found the protective suit and checked the upgrade options.

[Protective clothing]

upgrade direction: advanced protective clothing.

Branch ↓

Heat-resistant (200): A heat-resistant film is added to the outside to resist high temperatures for the wearer.

Portable backpack (500): A detachable large-capacity backpack is added to the back, and it automatically ignores the internal weight of 40 pounds.

At the moment, there are only two upgrade options left for the suit.

Qin Jian naturally didn't hesitate, and upgraded all of the two!The

points were immediately 1003, exactly 1000 left.

Not to mention the heat resistance, in the future, the corpse may be burned every day

, and it is inevitable that it will be close to the flames, and it will definitely have to be used! Portable backpack, not to mention!

It is equivalent to bringing a large bag that can easily transport materials, and even bringing its own black technology, ignoring the

weight of 40 catties inside! So in the future, not only can he hold weapons and materials, but even fill 40 catties of things, he still will not have any feeling of weight, and he will inevitably be as light as a swallow when he runs!

All the options have been upgraded, and the suit has been renamed to Premium Suit.

Good guys, this day has filled up three items in a row!

red pills, barbed wire, hazmat suits.

It's all been upgraded so hard, the big brother of the system, can't he give more rewards on the settlement points tomorrow?

Qin Jian didn't feel that he was daydreaming, but really felt that there would be additional rewards in the settlement of points tomorrow.

After all, there is activity, and early this morning, he is so active!

The remaining 1,000 points, Qin Jian has no intention of staying.

He remembered the M9 pistol, and there was only one upgrade option left.

"Open upgrade options!" [

M9 Pistol]

Upgrade Direction: Military M9 Pistol

Branch ↓

Ammo (50): Replenish 50 rounds of ammo.

Durability (500): The entire gun body is replaced with high-grade materials to increase the service life.

"Ammo" is not an upgrade option, so the M9 really only has one upgrade option left at the moment.

"This thing has to be upgraded, after all, it's so important.

Qin Jian thought in his heart, and immediately spent 500 points to upgrade the "Durability" option.

In the next second, the body of the M9 suddenly lengthened a lot! The overall look was even darker and more exquisite! The

battle with Gu Yiming yesterday made Qin Jian feel

that the loss of the M9 was very serious! Because of the continuous shooting, loading, and shooting, the muzzle of the M9 at that time was already very hot, and even the hot barrel was red, Qin Jian was afraid that the M9 would accidentally injure himself by exploding in the next second.

But now that the durability has been upgraded, he doesn't have to worry.

It doesn't matter if you shoot casually or stay overnight! Anyway, there is black technology on top, what are you afraid of?

With all the M9 options upgraded, Qin Jian has continuously upgraded four items to the second level today.

[Military M9 Pistol]

Upgrade Direction: Special M9 Pistol

Branch ↓

Ammo (50): Replenish 50 rounds of ammo.

Drum (2000): Converts all expanded magazines into a large drum with a capacity of 64 rounds.

Infrared (1000): The addition of infrared device can effectively increase the accuracy of sweeping.

Lighting (1000): Added lighting fixtures to facilitate night combat.

Fatal Bullet (3000): For every three bullets fired, the fourth bullet deals double damage.

"What a awesome feeling!"

Qin Jian couldn't help but sigh, and said in his heart that an M9 pistol has been upgraded and upgraded, and its firepower is about to catch up with

the machine gun! First of all, this drum, damn, it has been directly expanded to 64 rounds, which is more than the reserve ammunition of the light machine gun!

Infrared increases the accuracy of strafing, this is beyond doubt, after all, you can use infrared to aim at the enemy without aiming, how can it not be hit?

Lighting is also very important, so that you don't need to use a flashlight when you go out at night.

The last item, everyone who understands it, has directly become a black technology, one shot catches up with two rounds of damage! What must not be broken?
