Global Disaster: I have a dungeon

For Liu Chen, 10 million, there are more or less.

But as long as it can ensure the safety of the underground city, Liu Chen, the system coin, is still willing to spend.

【Ding! .

[10 million systems have been deducted! .

[The idea of the host is being realized, please wait.]

As the bingling sounded, the city walls quickly changed.

The city wall extends a little outwards and gradually becomes thicker.

Although the material is still the same material, the naked eye becomes particularly fine.

Tap gently, the dull sound spread, which made people feel unspeakable.

“This defense can at least make me invincible!”

As soon as the defense was improved, Liu Chen relieved slightly.

Immediately afterwards, he put forward ideas to the Black Technology Creation Camp.

“Can the power of cannonball increase 100 times?”

[Black Technology Creation Camp has received your idea, and is analyzing and statistical the amount of system currency required for this idea]

【Ding! .

[Insufficient currency balance of the host system, it is impossible to achieve this idea! .

Liu Chen sinks his eyebrows.

More than 30 million system currencies could not realize this idea, and it seemed a bit overwhelming.

After thinking about it, he said again: “Can the power of cannon bells increase by 10 times?”

【Ding! .

[Insufficient currency balance of the host system, it is impossible to achieve this idea! .

Liu Chen: “.”

Is this too much?

Liu Chen was speechless for a while, but he didn’t go down.

Even if the power of the shell can increase 5 times and 8 times, let him spend tens of millions of system coins to achieve it.

How do you say it is still not cost -effective.

It is better to upgrade the city’s defense tower after upgrading the dungeon to the 20th level!

Thinking of this psychology, Liu Chen quickly operated.

“Upgrade the dungeon!”

After 5 consecutive points.

【Ding! .

[Congratulations to the host to successfully raise the dungeon to level 20! Unlock new buildings: nuclear pollution purification station! .

[Because the level of the dungeon is up to 20 levels, the dungeon tax system is now opened. .

Since the level of the dungeon reaches level 10, new buildings will be unlocked every 5 levels, so Liu Chen is not surprised at all.

[Is the nuclear pollution purification station immediately? .

With this building so good, with it, Liu Chen no longer has to worry about being used by a large -scale use of nuclear weapons to use nuclear weapons to threaten it with a large scale.

Of course, we must build immediately!

However, Liu Chen now does not use it. After all, these countries still have the value of use. Liu Chen still has to let them help themselves.

So after building it, I did not manage it, but put my eyes on the so -called tax system.

[Host: Liu Chen! .

[Dungeon level: 20! Area: 53.76 square kilometers! System currency required for the next level: 10752000! The number of residents in the dungeon needs 200! .

[The number of residents of the current dungeon: 20, can be levied tax: 2 (0.1 system currency per person per person every day!)]

[Existing buildings: workshop (level: 15), research institute (level: 15), urban defense tower (level 4) X3, power plant (level: 15), medical office (level: 15), driving test simulation base ( 5), aircraft launch well (grade: 5), satellite launch well (level: 5), black technology creation camp (level: 5), training room (level 5), nuclear pollution purification station (level 1), oxygen dispellation station (Unprocessed), the number of resources and mines: 40. .

[System currency: 26802404! .

After watching this tax system, Liu Chen was in the mist.

“What do you mean? There are 20 people in the underground city in my underground city, and you collect me 2 system currency every day?”

The system quickly answered: “It is the system issuing 2 system currency to you every day.”

“Oh! ~ It means that’s what it means.”

However, this is the tax.

There are so many people and fewer people, it is not interesting.

“Do you want me to be the savior?”

Liu Chen muttered so, but didn’t say much.

When the savior is such a thing, let it go, and when it is strong, it is worth doing it, but now, even if it is.

Although the area of the dungeon has reached more than 80,000 acres now, there is no land.

He has the entire farm, the entire pasture, the entire orchard

When you put your safety coefficient and quality of life, come and think of others.

But the 200 people who are stuck in the stuck can still be solved.

After all, farm pastoles, or some people have to take care of

At this point, Liu Chen immediately called Li Henian to make him arrange someone.

Li Henian naturally did not say a word, and immediately arranged.

After the incident was handled, Liu Chen did not work on the tax system.

Instead, he gathered on the tower of the city.

Now the dungeon has reached level 20, and the nuclear gathering missiles have also been created, and the conditions for upgrading the tower to upgrade the city.

Immediately opened the attribute panel of the tower of the city and upgraded.

【Ding! .

[Congratulations to the host to successfully raise the tower to level 5! .

[Missile launch well +1! The range+500km! High -speed melee gun +2! Range+100km! .

[All cannonballs launched by the tower of the city+200%! .

Hearing these voices, Liu Chen’s mouth was flush.

Obviously not very satisfied.

Since he knew that there were alien beast queens in the ordinary beast period, he probably speculated that there was also a alien beast king in the period of mutation.

This improvement

It is even worse to deal with the alien beast king who is able to deal with ordinary beasts, but want to deal with the mutant period.

Look at the attribute panel of the tower defense.

【City Defense Tower】

[Level: 5, upgrade the next level requires system currency: 150,000, dark material missiles: 100 pieces, the level of dungeon is needed to reach 30. .

[Load weapon: missile launching well X4! High -speed melee gun X4! .

Liu Chen: “.”

Dark material? Level 30?

How much does this have to spend?

“Forget it, I do n’t want to disturb myself. Take a step and look at it. Think about it ten days ago. I still use the artillery. Now, huh, even the nuclear fusion missiles are used.”

Yeah, there have been such a big change in just ten days.

After those days, who knows what it will become?

After the city defense tower is upgraded.

Liu Chen took a clean again and raised other buildings over again.

“Okay, basically that’s it. If the mutant beast is coming, there is no way,” there is no way. ”

On June 4, 2021, 20 o’clock.

It was already time to reach the night, but the sky of Yangcheng is still bright!

In addition, in the west of the sun, the fire burning clouds are connected, and the white rainbow and light run through the clouds, as if there is a sharp sword, dividing the fire to the cloud into two, it looks very gorgeous.

Beautiful is beautiful, but the people on the blue star are full of clouds.

“It’s so weird!”

“This is the natural phenomenon of Changhong Guanri?”

“Changhong Guanri is a sign of great fierce, indicating that there is a big disaster!”
