Global Disaster: I have a dungeon

The more I thought, the more Liu Chen was shocked.

He finally knew why there is something like oxygen dispellation station!

It turned out that this building was not used at all.

It seems that I am still too young.

“Build an oxygen dispersion station immediately!”

Yes.

Liu Chen had not built this building before, but now he knows that the disaster in the next stage is that the concentration of oxygen is increased, and he immediately acts.

【Ding! .

[Congratulations to the host’s successful construction of oxygen dismissal stations! .

[Since the host establishes the oxygen dispellation station for the first time, the system will add 5 days of the dungeon constant oxygen time! .

[Do you immediately use the 5th dungeon constant oxygen time? .

Of course not to be!

It has not been in the disaster stage now. Is it wasteful?

However, Liu Chen was still puzzled when he heard such a tip.

“What do you mean?”

“Even if this oxygen dispel station is built, it can’t be used for free?”

The system answered: “Yes.”

“The time of constant oxygen needs to spend system currency for purchase!”

Liu Chendao: “What price?”

“There are many variables, including the space, time, and oxygen concentration of the dungeon.”

“For example, the oxygen concentration reaches 70%. Based on the current space, it will cost 5 million systems every day!”

When Liu Chen heard this, his face was green.

5000000!

When Lao Tzu’s system currency was shot?

Fortunately, he has hoarded a lot of system currency now to ensure that his dungeon city holds this disaster.

But what about the satellite city?

He can’t ignore it. In the disaster of this oxygen concentration, except for the taxes received by the satellite city, the rest is the rest, but there is no system currency input.

“You have to establish an oxygen dispellation station over there!”

Therefore, Liu Chen immediately issued a instruction to the system: “Install a oxygen dispersion station for all four satellite cities!”

【Ding! .

[Successfully received the host instructions! .

[It is deducting the host 2000,000 system currency! .

[Establishing oxygen dispellation stations at four satellite cities! Please wait.】

“What? It takes 200 million to build oxygen elimination stations!”

“Are you fucking, aren’t you teasing me?”

Liu Chen’s headache. Now it is time to spend system currency, each place costs a lot of system currency!

And when the trouser belt, the system actually started to wool!

Is that human being?

Originally he planned to upgrade the dungeon, now

He can only be glad that he did not upgrade immediately!

“Hey! Okay, okay, just play, play with everyone, let’s die together!”

Jiandu has been built, and Liu Chen will naturally not be tangled on this issue!

Rotating to look at the various gift packages that have not had time to open in the system space.

He now watched these gift packages, and he wanted system currency without any need.

“Open the 10 -level task package!”

【Ding! .

[Successfully received the host instructions! It is opening the 10 -level task package! .

【Ding! .

[Congratulations to the host to get a level 30 helicopter of the dungeon! .

[Do you use it immediately? .

Liu Chen heard such a information, and it was bright.

This stuff is fine!

Level 30 dungeon hedging card!

Doesn’t this mean that you have saved your system currency for nearly 10 billion? Intersection

That dare!

However, now in a special period, this stuff will not be used for the time being.

Otherwise, after use, the area of the dungeon rises a lot.

At that time, the area is large, and the cost of oxygen dispellation stations will rise again!

Therefore, this stuff will not be used for the time being!

“Open the survival reward package!”

【Ding! .

[Successfully received the host instructions! Open the survival reward package! .

【Ding! .

[Congratulations to the host for getting dark matter research cards, you can study dark material energy for free after use! .

[Do you use it immediately? .

Liu Chen: “.”

This system is really interesting!

When I did n’t come when I was fighting a strange beast, now a good guy, I gave all the waves.

Liu Chen was depressed for a while.

“Continue to open a staged survival gift package!”

【Ding! .

[Successfully received the host instructions! It is opening a staged survival gift package! .

【Ding! .

[Congratulations to the host for getting 2 million tons of materials! .

[Do you use it immediately? .

Liu Chen’s tears are full of tears!

Finally it is useful!

The disaster of increased oxygen concentration is coming soon. In addition to oxygen is his biggest threat, the supplies are also quite scarce.

You know, human beings have been suspended for two months.

Moreover, after two catastrophe, Lan Xing has been hit by devastating!

Don’t look at what planting base breeding bases have been built in the underground city.

After waiting for the oxygen concentration to increase, maybe maybe it will become!

The supplies that still exist

Liu Chen dares to guarantee that people who survive the current surviving will definitely use it for a month!

Although these 2 million tons of supplies are only a good salary, at least it can be topped for a while.

As for the later things, you can only take a step at one step.

After reading it, Liu Chen turned around and called Li Henian again.

Li Henian seemed to be taking a good rest.

When Liu Chen called, he was lazy and weak.

“What’s up?”

Liu Chen said: “The disaster in the next stage, there will be 12 days.”

As soon as he said this, Li Henian was in an instant.

“Do you know what the disaster is in the next stage?”

Liu Chen nodded: “It is an oxygen concentration improvement.”

“While there is still time now, you can quickly let your people hurry up and study. What will affect people?”

“Quickly make a report!”

“How to deal with it!”

“Also, if you don’t want to give up your people, then hurry up to collect materials. There may be various uncertain disaster behind you waiting for us.”

“At that time, if the grain reserves are not enough, they are likely to be unable to bear it!”

Li Heian said: “Okay, I immediately let people make a report!”

“However, it is too dangerous to go out to collect materials now.”

“In order to kill the super -alien king some time ago, the entire blue star is now some horrible germs!”

“Going out now to find materials, it is almost equivalent to finding death.”

Liu Chen sinks his eyebrows, he forgot this stubble!

“I think of ways to see if I can kill these germs!”

Speaking, Liu Chen hung up the phone.

Then opened the system and chose the institute-biotechnology.

“Is there a powerful pharmaceutical agent, give a formula!”

【Ding! .

[It is matching the items needed by the host, please wait.]

【Ding! .

[What are you looking for: 8835 ultimate bactericide? .

“Is this good effect good?”

The system answered: “Very good. After the spray, no matter what bacteria, it will be disappeared.”
