Global Cataclysm: Start building a dungeon

There is only such a chance!

Therefore, in this third stage of catastrophe, the survival points used will definitely far exceed that of the second stage!

At this moment, any way to obtain survival points is very important to Ye Liangren!

And this time the transaction.

It is the most important among them!

after all.

There are only seven days before the meteorite falls on the blue star.

In this case, the official must have known the news without any surprises!

And in the case of deploying defenses as well.

The materials traded this time are the core materials for deploying defenses!

Fortunately, this time the transaction was still carried out!

Ye Liangren breathed a sigh of relief.

Subsequently.

Look down the viewing angle.

There's a little virtual screen in there.

"Ding!The system upgrade is successful!Do you want to open the meteorite response interface? 』

"OK/No"

Ye Liangren took a deep breath.

Immediately clicked the OK button at the bottom of this virtual screen.

next moment.

A large virtual screen popped up.

『Third Stage Catastrophe: Meteorite Response Interface. 』

"Countdown to Meteor: 151:32:28. 』

"Defense module! 』

"Weapon module! 』

"Purification module! 』

Looking at these three modules, Ye Liangren hesitated for a moment, then clicked on the weapon module.

In an instant, another large virtual screen popped up.

"Weapon module:

『Particle Decomposition Beam: When used, it will emit a beam with a diameter of half a meter, which can directly decompose any object it hits into a particle state, and can easily penetrate meteorites!

建造发射基地，所需材料：沙石100000kg、纯铁50000kg、钛合金20000kg、铝合金20000kg、铜5000kg、纳米材料100kg、能源石200颗。

To create a particle decomposition beam, materials are required: 10 energy stones, 50kg of nanomaterials, and 60mg of particles. 』

『Super strong pulse resonance missile: After use, it can launch a pulse resonance missile. When the missile explodes, it can shatter all objects within a diameter of three kilometers! (Note: Detonate inside the meteorite, the effect is better)

建造发射基地，所需材料：沙石200000kg、纯铁60000kg、钛合金30000kg、铝合金30000kg、铜8000kg、纳米材料200kg、能源石400颗。

To manufacture a pulse resonance missile, materials are required: 20 energy stones, 100kg of nanomaterials, and 60mg of particles. 』

『Railgun: After use, it can launch a beam of electromagnetic guns that can move in a short distance in a straight line within ten seconds...』

"..."

After reading the descriptions of all weapons in the weapon module.

Ye Liangren frowned fiercely.

The next moment, he spoke immediately.

"System, upgrade the exchange system."

"Ding!Consume 2000 survival points to upgrade the exchange system, the upgrade is successful! 』

"Remaining survival points: 72420. 』

"Exchange System"

"Level: 3. 』

"Upgradeable! 』

"Upgrade direction: level 4!Survival points needed: 4000. 』

"Current exchangeable list:

Pure iron 1kg: 10 survival points!

Titanium alloy 1kg: 100 survival points!

Aluminum alloy 1kg: 200 survival points!

Copper 1kg: 250 survival points!

1 energy stone: 500 survival points!

Nano material 1kg: 600 survival points!

Super Alloy T1-V1kg: 600 Survival Points!

Unlocked list:

Level 5: Particle particles, vibranium...etc. 』

"If you want to exchange for particles, you still need to upgrade to another level?"

Ye Liangren frowned and spoke again.

"System, upgrade the exchange system again."

"Ding!Consume 4000 survival points to upgrade the exchange system, the upgrade is successful! 』

"Remaining survival points: 68420. 』

moment.

Ye Liangren looked at the exchange prices of the two newly appeared items.

『Vibrating gold 1kg: 700 survival points! 』

『1 mg of particles: 700 survival points! 』

Ye Liangren shook his head with a smile.

"Sure enough, at this price, weapons are simply not something I can afford!"

"In particular, to launch this weapon, a launch base needs to be built!"

"Although, a launch base should be able to be used multiple times."

"However, every light beam and every missile still needs to consume a lot of resources to manufacture..."

"In other words, each launch will consume at least a dozen or 20 survival points. This... there is no million survival points, so there is no need to think about it. Relying on weapons to deal with the coming meteorite this time!"

Chapter 286 Defense Module

Ye Liangren sighed lightly.

in fact.

He knew early on that the horror survival point needed to manufacture weapons to solve this catastrophe was simply not something he could afford.

However, before upgrading the exchange system, after all, he still had a thought in his heart.

Maybe?

What if?

How many survival points are not needed to exchange these materials?

And, the main reason is.

In the introduction of the system, the use of these weapons has actually been explained clearly.

For example: Particle decomposition beams cooperate with super-strong pulse resonance missiles.

First use the decomposition beam to evenly penetrate four or five holes of the meteorite.

Then launch the super-strong pulse resonance missile into these four or five holes.

One detonated.

Not surprisingly, the meteorite can be directly shaken into powder.

In this way, this catastrophe can be resolved directly.

At most at most.

It is the radiation carried by meteorite fragments that floated down overwhelmingly.

But, isn't there a purification module?

Make a few more radiation purifiers, and the catastrophe this time can be completely resolved!

Honestly, this is totally the easiest solution.

Moreover, there is almost no risk!

However, it is not the same to completely strengthen the defense.

When meteorites fall, too many unexpected situations are prone to occur.

Even if it can take care of 90.00% nine, but there is still that one percent!

The so-called, don't be afraid of ten thousand, just in case.

Therefore, he upgraded the exchange system and prepared to calculate the survival points needed to make weapons to solve the meteorite.

However, this upgrade.

After knowing the exchange price of those materials.

Ye Liangren immediately dismissed this idea.

Just the survival point required for each missile is completely beyond his affordability, let alone a launch base!

After taking a deep breath.

Ye Liangren turned off the weapon module.

Then, click on the defense module.

In an instant, a large virtual screen popped up.

"Defense module:

『Superconducting resonant glass: After installation, the glass will not block and refract sunlight. People, plants, and buildings can still be exposed to sunlight. At the same time, it can isolate 90.00% of the harmful light to the human body!And, the defense is extremely strong, which can effectively block the impact of meteorites, and can be repaired automatically! (Note: It takes 100 pieces of glass to cover the entire river city!)

Each piece of superconducting resonant glass requires materials: 1000kg of pure iron, 500kg of sand, 1kg of nanomaterials, and 1 energy stone』

『Superalloy wall: After installation, the defense of the wall is greatly improved, which can effectively block the impact of meteorites and the destructive power of most weapons. (Note: 100 superalloy walls are required to surround the entire Jiangcheng! The current steel wall can be upgraded to a superalloy wall, and the materials required for the upgrade are halved!)

每一块超合金墙壁，需要材料：钛合金500kg、铝合金300kg、超合金（T1-V1）1kg、能源石1颗』

『Buffering device: It can be installed on superconducting resonant glass and superalloy walls. A single buffering device can cover the whole, greatly improving the defense of superconducting resonant glass and superalloy walls!

Each buffer device requires materials: 20kg of vibration gold, 20kg of nanomaterials, 20mg of particles, and 20 energy stones』

『Anti-shock device: It can be installed on the ground with a range of 20 kilometers. It sends shock waves on the ground every moment to continuously compress the geological structure. It can perfectly solve the earthquake problems caused by impacts, impacts, continental plates, etc.!

Each anti-vibration device requires materials: 20kg of vibration gold, 20kg of nanomaterials, 20mg of particles, and 20 energy stones』

"..."

After seeing the function of these items and the required materials in the defense module.

Ye Liangren heaved a sigh of relief.
