"System, is there a way to keep these two dogs from mutating?" Chen Nuo looked at the second fighter jet with a puzzled look on his face and asked in his heart.

After all, these two dogs are quite well-behaved, and Chen Nuo doesn't dislike them.

Furthermore, Fighter 2 likes them very much, so Chen Nuo naturally asked like this.

"Yes!" As the system's reply emerged, in front of Chen Nuo's eyes, the light curtain appeared:

"Air purifier: It can remove the smell in the air, purify the air, and upgrade to level 10 to remove harmful substances such as viruses in the air! It takes ten points to upgrade to purchase!"

Seeing this, Chen Nuo was stunned.

"If you purchase and upgrade to level 10, how many upgrade points are needed?" Chen Nuo asked hurriedly.

At the same time, seeing Chen Nuo standing there with frowning, Fighter 2 and the others were stunned and confused.

But no matter how confused they are, they dare not ask why.

...

“12780 upgrade points!”

Upon hearing this, Chen Nuo was stunned and couldn't help but ask:

"How many upgrade points do I have left now?"

“13146 o’clock!”

If you purchase and upgrade to level 10, then you will have less than four hundred upgrade points left.

Thinking of this, Chen Nuo couldn't help but ponder.

Then his expression became a little subtle.

"But even if they will not mutate here, once they go out, they will mutate." Chen Nuo thought of this.

"Ding, warm reminder, after their evolution, their immunity will be enhanced and they will no longer be easily invaded by viruses!"

With the system prompted, Chen Nuo subconsciously looked at the dog in front of him and the fighter plane No. 2 in front of him.

"It's okay." After thinking about it, Chen Nuo said to the fighter jet No. 2.

After saying that, he turned around and headed towards the living room outside.

But this scene surprised the fighter jet 2 a little.

Then, subconsciously looked at the two dogs.

"Master, don't you want to eat dog meat?" Aside, the drone flew over and muttered, touching his chin.

After saying that, it poked the fighter jet No. 2 and said with a wicked smile:

"Your opportunity has come. Now I will kill these two puppies and give them to my master. Maybe I will make a contribution. After all, this dog is so dirty and shitty, even I feel disgusted."

"If you don't speak, no one thinks you are a mute." Fighter 2 rolled his eyes at it.

...

"System, choose to buy an air purifier and upgrade to level 10!" Chen Nuo ordered while sitting on the sofa.

Although it would be a bit unworthy to do this for two dogs.

However, Chen Nuo did not hate those two dogs.

Furthermore, Fighter 2 likes them very much.

Therefore, Chen Nuo would not think that this would be a bit unworthy.

"Ding, you consumed 12,780 upgrade points and purchased the air purifier and upgraded the air purifier to level 10!"

"Please select the installation location!"

"System, automatically help me to follow the best position." Chen Nuo ordered as the system prompt sound appeared.

"Ding, the installation was successful!"

Soon, the system prompt sound appeared.

On the door on the first floor of the shelter, something similar to an air conditioner appeared out of thin air.

That's the air purifier.

With the installation and opening of the air purifier, Chen Nuo could clearly feel a fresh air.

...

Next, Chen Nuo asked Heipi, Huolala and UAVs No. 1 to collect materials.

At the same time, he used the remaining more than 300 upgrade points to purchase 30 energy crystals, and ordered Fighter 1, Fighter 2 and UAV to go to the black hole without magic arrays to help him plunder the upgrade points.

The reason why both of their teams have unmanned reconnaissance aircraft is very simple.

Now the temperature continues to rise, and some people who lack food will inevitably come out to find food.

Therefore, the capabilities of the unmanned reconnaissance aircraft were revealed.

Of course, although almost all people in Zhennan City have been taken to the shelter of the capital by the state, they still have to be aware of what they should be guarded against.

After all, Chen Nuo had previously encountered the group of prisoners who had not entered the official shelter of the capital.

...

After doing this, Chen Nuo entered the retreat room and began to practice.

After all, after learning about the fourth wave of disasters, it still had a great blow to Chen Nuo.

At least, he needs to have the power to defend against all this.

...

February 28, 2045.

This is the third day after the third wave of disasters.

At this time, due to the rise in temperature, people walked out of various places and began to look for food.

The government has also begun to continue to take over those who have not yet entered the official shelter of the capital.

At the same time, enhance the defense capabilities and food of the official shelter of the capital.

...

March 1, 2045.

On the fourth day of the third wave of disasters, on this day, the temperature rose to above zero, and the sunlight penetrated the clouds and evaporated the white snow on the ground.

The heavy snow began to melt.

The government, or urban shelters that have not all visited the official shelters of the capital, have also begun to strengthen their waterproofing systems.

After all, no one knows whether the snow will cause the level to rise after melting, causing disasters such as tsunamis.

...

March 2, 2045.

This is the fifth day of the third wave of disasters.

On this day, the survivors in the remaining urban shelters were successively taken to the capital shelter.

At the same time, the heavy snow melted and the temperature gradually rose to around 20 degrees above zero.

However, what surprised people was that although these heavy snow melted, the global level rose.

However, as expected, disasters such as tsunamis that flooded cities did not occur.

This made people feel relieved.

Moreover, on this day, as the sun shines, strange things happen.

In the sky, a layer of transparent and pale gas floats in the air.

These gases are similar to fog, but they are not as thick as fog, but are extremely sparse. Moreover, after absorbing them, people can't help but feel energetic.

All of this surprised people.

...

March 3, 2045.

On this day, the pale white object began to become more and more intense.

At the same time, the remaining urban shelters were also taken to the capital shelter by the government.

At this moment, the people from China gathered.

Not only that, some magical things also happen among people!

...

On this day, Chen Nuo broke through to the third level of Qi Refining Realm!

At this moment, his strength soared!

At the same time, he also felt the concentration of spiritual energy in the retreat room soared.

This surprised him:

"System, when is it now?"

“March 3, 2045.”

Hearing this, Chen Nuo was stunned.

This time, he did not set a time for himself to get out of the level of Qi Refining Realm with all his strength.

So, he couldn't help but be surprised at this moment.
Chapter completed!
