"Okay, I'll raise the retreat room one level!" Hearing this, Chen Nuo didn't think much and directly ordered.

After all, the higher the concentration of spiritual energy, the more divine it will be. Therefore, of course, he has to upgrade the retreat room more.

"Ding, you consume 100 upgrade points to increase the level of the retreat room. The area of ​​the retreat room remains unchanged, and the concentration of the spiritual energy is increased from 10% to 15%!"

"If you upgrade to another level, you will add 5%?" Chen Nuo was stunned when he heard this.

"Can I upgrade my remaining upgrade points now be upgraded to the retreat room again?" Chen Nuo asked.

“Not enough to improve for the time being.”

Upon hearing this, Chen Nuo had to give up.

At the same time, he has already arrived at the fifth floor.

Here, there is an empty road in front of the entrance and exit of the elevator and stairs, and there are two rooms on both sides.

Not only that, the signs of "Simulation Practical War Room" and "Settlement Room" are also posted on the doors of these two rooms intimately.

Seeing this, Chen Nuo didn't think much about it and went into the retreat room first.

He now wants to improve his strength first, and then enter the simulation combat room to practice his performance skills.

In the retreat room, there is a 50-square-meter-wide open space, and the center of the open space is a circular open space surrounded by a circle of ten pillars.

And the moment Chen Nuo came in, he could feel a powerful spiritual energy lingering in this room!

This made him widen his eyes, then closed the door and came to the place where the spiritual energy was most dense.

That is the center surrounded by the pillar.

After being surprised, he sat cross-legged on the ground and began to practice with his eyes closed.

In an instant, the majestic spiritual energy seemed to turn into a tornado and rushed towards Chen Nuo. The scene was so spectacular that it was surprising.

...

Time flies quickly, and three days pass by in a flash.

January 17, 2045.

Because of the three-day hunting of the Earth Coronary Beast, many people died in it, and some official shelters were also breached, causing countless deaths.

However, because the military quickly sent troops and arms, most of the official shelters were still defending their positions.

But the only thing that makes people desperate is that there are so many of these nuclear beasts after being hunted for four days!

...

At the same time, in the shelter of the Supreme Command of the Military.

The man looked at these battle situations with a serious expression.

"Have you heard from the troops sent out to drop nuclear bombs on black holes caused by planetary debris?"

After several days of confrontation, countries around the world have gradually controlled this sudden catastrophe.

Although many people died, it was much better than the situation when they were busy dealing with the catastrophe at the beginning.

So, they made time to send people to black holes in various places to launch nuclear weapons.

In order to kill more such monsters and gain some opportunities for relief for shelters in various urban areas.

At this moment, after hearing this, a man in front of him turned around and said:

"Because there are too many strange birds, the troops heading to drop nuclear bombs were directly intercepted on the road, and some even lost contact!"

"How is that..." The man's solemn face was even better.

For a moment, the atmosphere of the entire supreme command became subtle.

This time, the danger was caught off guard.

No one would have thought that such a danger would suddenly come.

At the same time, it also lets people know that the United States is sometimes not completely unbelievable.

...

At this time, Chen Nuo's refuge.

In the retreat room, Chen Nuo slowly opened his eyes.

Immediately afterwards, a terrifying aura emanated from his body instantly!

Not bad, he broke through!

Body refining realm, fifth level!

In three days, he rose from the fourth level of the Body Refining Realm to the fifth level of the Body Refining Realm. This speed is very fast.

You should know that the higher the state, the slower the practice.

As he stood up slowly, Chen Nuo exuded a terrible aura all over his body.

But soon, he skillfully put away the breath, then twisted his neck and moved his body.

"The fifth level of the Body Refining Realm, this feeling of being full of power is really good..." Chen Nuo clenched his fists with both hands, felt this power, and his eyes shone.

"It's almost done, three days have passed..." As he murmured, he walked out of the retreat room and then returned to the first floor to take a shower.

...

An hour later, Chen Nuo walked out of the bathroom and then asked:

"System, how many upgrades do I have now?"

"25455 points! And, this value is still increasing!"

Upon hearing this, Chen Nuo paused, his whole body was shocked, a little shocked.

"Damn it? There is an upgrade point of 25,000 in three days?! Hiss..."

He burst into thick and took a breath of air conditioning.

"This...is no less than the feeling of going to an insurance company to receive more than 53 million yuan..." Chen Nuo only felt that the feeling of getting rich was very good.

After saying that, he directly ordered the system:

"System, I will upgrade the shelter level and choose to expand the shelter area!"

"Ding, you have consumed 3,200 upgrade points to improve the shelter, and the area of ​​the shelter has been increased from 40 square meters to 800 square meters! The thickness of the armored door has been increased from 35 cm to 40 cm! The thickness of the wall has been increased from 35 cm to 40 cm!"

"Host: Chen Nuo!"

"Sanctuary level: 8! (6400 upgrade points are required for upgrade!)"

"Sanctuary equipment: Level 8 armored door, Level 3 water source station, Level 4 power station, Level 6 scientific research base, Level 3 automatic elevator, Level 3 breeding farm, Level 2 retreat room, Level 1 simulation practical combat room!"

...

"It will take more than 6,000 to upgrade again..." Chen Nuo felt a little annoyed, but upgrading is necessary, there is no need to worry about it.

Furthermore, he has made big moves now!

But after seeing him murmur, he said directly:

"System, I want to buy a car manufacturer and set it on the redundant position on the second floor."

"Ding, you spend ten points to upgrade and purchase a car manufacturer with an initial area of ​​50 square meters!"

"Host: Chen Nuo!"

"Sanctuary Level: 8! (The upgrade requires 6,400 upgrade points!)"

"Sanctuary equipment: Level 8 armored door, Level 3 water source station, Level 4 power station, Level 6 scientific research base, Level 3 automatic elevator, Level 3 breeding farm, Level 2 retreat room, Level 1 simulation practical room, Level 1 vehicle manufacturing factory!"

"Ding, the location of the car manufacturer has been set up successfully!"

With the system's prompt sound, Chen Nuo thought for a while and then ordered:

"Elevate the level of the car manufacturer to level three!"

"Ding, you consume 150 points to upgrade the car manufacturer to level three, and the area is increased from fifty square meters to two hundred square meters!"

Upon hearing this, Chen Nuo said again:

“How many upgrade points are left now?”

"22555 upgrade points! And, this value is still increasing!"

"There are 20,000 points left." Chen Nuo nodded and couldn't help but ponder.

These are enough to buy two thousand energy crystals!
