Global Catastrophe: I Am Cultivating Immortals in the Refuge

As for why Chen Nuo chose to upgrade the heater on the fourth floor, the reason is simple.

The fourth floor is the planting area and the place where the animals are raised, so the temperature must not be low there.

Otherwise, animals will die once they get sick, and once plants are frozen, then Chen Nuo's efforts will be lost.

Therefore, Chen Nuo first chose to upgrade the heater on the fourth floor.

Of course, it is impossible to directly upgrade to the tenth level, after all, he has so many upgrade points.

Furthermore, you have to keep your hands on everything, otherwise, you will definitely die miserably.

"Now the temperature of the fourth layer can be increased to 80 degrees by that time, plus the artificial sun, it should not be afraid." Chen Nuo secretly analyzed.

As for the car factory, water source station and power station on the second floor, they are equipment and should be resistant to freezing.

Not to mention the scientific research base on the third floor and the closed room and simulation room on the fifth floor.

"The system, upgrade the heater on the first floor to five levels." Thinking of this, Chen Nuo ordered.

The first floor is where he sleeps and eats, and the temperature cannot be low.

However, the level of this heater does not need to be too high, after all, the human body can withstand a temperature of minus fifty degrees at least.

Therefore, he chose to directly upgrade the heater to the sixth level.

In this way, the temperature emitted by the heater will be sixty degrees.

Of course, if it is still too cold, he still has three heaters and stoves.

"Just for the time being, save a little, use the extra upgrade points to improve something else." Chen Nuo secretly said in his heart.

"Ding, you consume 770 upgrade points to upgrade the heater on the first floor to the sixth level, and the maximum temperature that the heater can heat up from ten degrees to sixty degrees!"

"System, how many upgrade points do I have now?" Chen Nuo asked after hearing this.

"11365 o'clock!"

"More than ten thousand points, then raise the heater on the first floor again!" Chen Nuo nodded and said.毊灪miaoshuyuan.com毊灪

"Ding, you consume 800 upgrade points to upgrade the heater on the first floor, and the maximum temperature that the heater can heat up from 60 degrees to 70 degrees!"

Upon hearing this, Chen Nuo then asked:

"System, now how many upgrade points are needed for the scientific research base to be upgraded again?"

"3,200 upgrade points!"

Hearing this, Chen Nuo didn't think much, and said directly: "Upgrade!"

"Ding, you consume 3,200 upgrade points to upgrade the scientific research base, and the area of ​​the scientific research base has increased from 600 square meters to 1,200 square meters!"

With the improvement of the system, Chen Nuo has taken the elevator to the scientific research base on the third floor.

At this time, because of the upgrade, the space of the scientific research base is much more spacious again.

"Scientific research, bring up the new craftable technology you have upgraded." Chen Nuo directly ordered.

"Okay!" As the scientific research answered, a light curtain instantly appeared on the center console.

"Anti-skid device: No matter what kind of vehicle it is, it can be equipped with an anti-skid device. After the installation, the vehicle will never brake instability on snow!"

Production needs: ten catties of iron, ten energy spars!

Can be installed on the vehicle for free!

Anti-freezing device: a device that can be installed on any machine to make the machine anti-freezing!

Production needs: ten catties of iron, one catty of copper, ten energy spars!

Combat yacht: not only can swim on the surface, but also has the ability to fire bullets!

Production needs: one hundred catties of iron, ten catties of copper, twenty energy spars!

Dark Metal: A metal that can't even be penetrated by Barrett's cannon!

A pound of dark metal requires ten energy spars to make!

...

Looking at the new technology in front of him, Chen Nuo's eyes lit up.

Anti-slip device and anti-freeze device...

This is simply a device for sending charcoal in the snow.

You know, when the temperature drops to one hundred degrees below zero, the ground outside is full of ice, and if this anti-skid device is installed on black-skinned them, then they can go out to help find materials.

Not only that, this anti-freeze device can also make the Autobots such as Heipi a little anti-freezing ability in the environment of one hundred degrees below zero.

As for the combat yacht, although this is good, Chen Nuo has no idea for the time being.

After all, he does not need water supplies now.

As for the dark metal, this one moved Chen Nuo the most.

You know, except for tanks, the defenses of other robots can be said to be like paper.

And this dark metal is obviously something that can enhance their defense.

"It's just that this dark metal is too expensive, and ten energy spars can make a catty..." Chen Nuo pondered.

Indeed, this is too expensive.

You know, the size of a car is estimated to require hundreds of catties of dark metal to make.

Calculating this way, one hundred catties of dark metal requires one thousand energy spars.

And one thousand energy spar needs ten thousand upgrade points!

"However, although this amount is terrifying, dark metal is an inevitable need for black leather." Chen Nuo secretly analyzed.

After all, in case someone accidentally discovers their secrets by humans, it shouldn't be too easy to deal with the current Chen Nuo with the weapons in human hands.

"Scientific research, how much iron do I have now?" Chen Nuo asked about this.

"32.6 Jin!" The scientific research answer is both accurate and fast~www.NovelMTL.com~ Chen Nuo's face darkened upon hearing this.

"It seems that tomorrow I must go out and collect materials on a large scale." He secretly said in his heart, and then returned to the first level.

Now, Chen Nuo can only choose not to make anti-skid and anti-freeze devices for the time being.

After all, the third wave of disasters has not yet begun, and his materials are not sufficient.

"System, I need to use 5,000 upgrade points to buy energy spar, and help me put it in the material warehouse of the scientific research base."

However, although these two devices will not be made now, the materials must be prepared first.

"Ding, you spent five thousand upgrade points to buy five hundred energy spars! Now it has been placed in the material warehouse of the scientific research base!"

With the prompt sound of the system, Chen Nuo has already reached the first floor.

10:34 minutes.

Looking up at the time, Chen Nuo turned on the computer, ready to take a look at the outside world.

However, because the disaster has just ended and the damaged system has not been fully recovered, Chen Nuo can't see the current related video at all.

However, because the signal was not damaged during the disaster, some comments from people also surfaced on major social platforms.

Click to open WeChat Moments. These days, the Moments of his friends have been updated, and the updates are still very busy.

Not only that, some groups are also lively.

Chen Nuo simply took a look at this.

After all, the circle of friends and comments posted by these people can't fully show the outside situation.

Therefore, Chen Nuo didn't pay much attention to these comments.

Looking at the time nearly eleven o'clock, Chen Nuo was about to go to bed.巗攮攮
