Global Catastrophe: I Am Cultivating Immortals in the Refuge

"503456 upgrade points!"

Following the system's notification sound, Chen Nuo was shocked at first, and then relieved.

Then, the corner of his mouth raised.

More than half a million upgrade points, not bad, not bad, very good!

"System, use 100,000 upgrade points to buy energy crystals!" Without thinking too much, he ordered directly.

After all, energy spar is a must among materials.

So, of course, the more the better.

"Ding, you spent 100,000 upgrade points to buy 10,000 energy spars! It has been stored in the material warehouse of the scientific research base!"

"Let me increase the heaters on the second, third, and fifth floors of the shelter by four levels!"

Chen Nuo pondered for a while, then ordered.

It was minus 50 degrees outside now, and the heater on the first floor in the shelter was only turned on at 30 degrees, so Chen Nuo didn't feel any cold feeling.

That is to say, when the temperature outside is minus 100 degrees, the heater in the shelter should be turned on to about 50 degrees, and it should not feel cold.

And, it's still a case of a little cold air coming in through the vents.

"Ding, you spent 1110 upgrade points to upgrade the heaters on the second, third, and fifth floors of the shelter to the fifth level, and the maximum heating temperature of the heaters has been raised to 50 degrees!"

Following the system's notification sound, Chen Nuo said again:

"How many upgrade points are left now?"

"402346 points!"

"Upgrade the shelter level!" Hearing this, Chen Nuo ordered directly.

"Ding, you spend 12,800 upgrade points to upgrade the shelter, the level of the shelter is increased to level 10, the armored door evolves into a primary invisible door that only has the ability to be invisible during the day, and the thickness of the invisible door is increased from 45 cm to 50 cm. The thickness of the surrounding walls has been increased from forty-five centimeters to fifty centimeters!"

...

Hearing this, Chen Nuo was startled.

A primary invisible door with daytime invisibility?

"What does this mean?" He was puzzled.

"That is to say, the current invisible door can only be invisible during the daytime!" The system replied immediately.

"How can this work? Upgrade!" Chen Nuo frowned, only feeling that something was wrong.

After all, if you can only be invisible during the day, what about at night?

"Ding, you consume 25600 upgrade points to upgrade the shelter, the level of the shelter is increased to level 11, the thickness of the invisible door during the day is increased from 50 cm to 55 cm! The thickness of the surrounding walls is increased from 50 cm to 50 cm Five centimeters!"

...

Hearing this, Chen Nuo frowned, and his expression became slightly subtle.

"How come the ability of the invisible door can only be invisible during the day? Doesn't it increase the ability to be invisible at night after upgrading?" Chen Nuo was a little puzzled.

According to common sense, it should be able to increase the ability to be invisible at night.

Just, why not?

"No, there is no. Besides, no one stipulates that after upgrading, the ability to be invisible at night will definitely be increased!"

Soon, the words of the system made Chen Nuo swallow hard what he wanted to complain about.

"This...unscrupulous profiteer!" Chen Nuo couldn't help complaining.

"Ding, warm reminder, the next upgrade, the invisible door during the day will gain the ability to be invisible at night, and become a complete invisible door!"

Suddenly, just as Chen Nuo complained, the system's notification sound appeared.

This made Chen Nuo stunned, and didn't know what to say...

"Let's upgrade again!" Chen Nuo gritted his teeth and ordered again without fussing about anything.

"Ding, you consume 51200 upgrade points to upgrade the shelter, the level of the shelter is increased to level 12, and the invisible door increases the ability to be invisible at night! The thickness is increased from 55 cm to 60 cm, and the thickness of the wall is increased from 55 cm to 60 cm. Ten centimeters!"

"Host: Chen Nuo!"

"Shelter Level: Level 12 (102400 upgrade points are required to upgrade!)"

"Refuge equipment: 12-level invisible door, 3-level water source station, 4-level power station, 9-level scientific research base, 3-level automatic elevator, 3-level breeding farm, 11-level retreat room,

Level 1 simulated combat room, level 3 car factory, heater! "

"Remaining upgrade points: 312746 upgrade points!"

...

Looking at the attribute panel in front of him, Chen Nuo only felt a sense of accomplishment.

You know, his shelter was only a few levels at the beginning, and there were not many equipments.

嬯寷 bⅹшⅹ●С〇 寷. But now, his shelter is already level 12, and the equipment is basically complete.

This feeling is like watching the son I raised grow up.

...

"System, how many upgrade points are needed to increase the concentration of the retreat room to 100%?" Chen Nuo asked what came to his mind.

After all, the third wave of disaster lasted for a month, and he planned to practice hard to reach the Qi Refining Realm.

At least, he must be able to fly with a sword, and ignore bullet attacks!

But now, the aura concentration in the eleventh-level retreat room is only 60%, which is not enough to make his cultivation speed skyrocket.

"Need 10506400 upgrade points!"

Following the system's answer, Chen Nuo froze.

"More than 10 million upgrade points?! This..." He couldn't help but gasped.

However, after rectifying his mood, he calmed down.

However, the next notification sound from the system made Chen Nuo almost breathless.

"Ding, a warm reminder, 100% concentration is not the highest. After all, there is no difference in the concentration of spiritual energy, but the more concentrated the spiritual energy, the faster the cultivation speed will be!"

Following the system's prompt, Chen Nuo only felt that he was out of shape.

However, after calming down, he turned to ask:

"How many levels can I upgrade the retreat room to with the remaining upgrade points!"

"Ding, you can upgrade to the fourteenth level!"

"That is to say, three levels can be increased, and one level can be increased by 5%, then the spiritual energy concentration after the upgrade will be 75%." Chen Nuo analyzed.

"Then how many upgrade points do I have left after upgrading?" He directly upgraded without impulse.

After all, you need to keep a record of everything you do. This is what his grandma taught him.

"23946 points!"

"There are still more than 20,000 yuan left, just enough to exchange for some talent pills." Chen Nuo rubbed his chin and thought.

"Let's upgrade!" Thinking up to this point, he ordered directly.

"Ding, you spent 288,800 upgrade points to upgrade the retreat room to level 14, the concentration of aura in the retreat room increased from 60% to 75%, and the area of ​​the retreat room increased from 200 square meters to 400 square meters!"

Following the system's answer, Chen Nuo did not speak, but fell into deep thought.

毊灪 miaobiku.com 毊灪. All of a sudden, I went from getting rich to getting rich...

After thinking about it, he looked up at the time, and then began to search the outside world.

However, after seeing the current external situation, Chen Nuo couldn't help but breathe a sigh of relief.

"It seems that the human side doesn't need me to worry." With a sigh, Chen Nuo went to get a bucket of instant noodles and started to eat dinner.

...

23:44.

At this time, the temperature around the world has reached a terrifying temperature of minus 89.3 degrees!

Moreover, the temperature is still dropping!

All of a sudden, heavy snow covered the whole world, making any place in the world a vast expanse of white.

巗攮攮. At this moment, the ice age has come!

But at this time, even if humans are constantly adding heating devices, it still seems so insignificant.
