"So, what is the next disaster and when will it come?"

While pondering, Chen Nuo suddenly asked.

"The host has not successfully survived the second wave of disasters and cannot be informed for the time being."

However, the systematic answer made Chen Nuo want to speak but stop.

"Since that's the case, then when will this wave of disaster end?" Chen Nuo changed his question.

The reason for asking this is because he died in the second wave of disasters very early in his previous life.

So, he didn't know how long the disaster would last, and whether there would be any disasters after that.

"Two days later!"

Upon hearing this, Chen Nuo was silent.

In other words, the second wave of disasters, like the first wave, lasts for seven days?

However, after thinking about it, Chen Nuo stopped thinking about it and said:

"System, how many upgrade points do I have now?"

"8655 points, and this value is still increasing!"

"How much level can this upgrade point improve the retreat room?" Chen Nuo asked after hearing this.

I have learned some practical experience, although not a lot, but now it is necessary for him to improve his strength.

"Can you directly upgrade to level 8! Is it upgraded?" The system's answer made Chen Nuo ponder.

Increase the concentration of spiritual energy by 5% at level 1. If you increase the concentration of spiritual energy by 30% again, you can increase the concentration of spiritual energy by 30%.

"If I upgrade to level six again, how many upgrade points will I have left?" Chen Nuo said in confusion.

"There are 2250 points left, but because this value is still increasing, this is not an accurate value!"

"After upgrading, the remaining upgrade points can also be improved in the scientific research base or something else... choose to upgrade!"

After Chen Nuo analyzed it, he immediately ordered.

"Ding, you have consumed 6,300 upgrade points to upgrade the retreat room, and the area of ​​the retreat room has been increased from 50 square meters to 200 square meters! The concentration of spiritual energy has been increased from 15% to 45%!"

"Host: Chen Nuo!"

"Sanctuary level: 9! (12,800 upgrade points are required for upgrade!)"

"Sanctuary equipment: Level 9 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 8 retreat room, Level 1 simulation practical room, Level 3 vehicle manufacturing factory!"

"The remaining upgrade points are 2275, and this value is still increasing!"

...

Looking at the attribute panel in front of you, Chen Nuo couldn't help but mutter:

"There are more than 2,000 upgrade points, why not improve the scientific research base again?"

After all, the technology in the scientific research base is far beyond modern, so it is still very necessary to upgrade this.

Thinking of this, he ordered:

"System, I chose to improve the scientific research base!"

"Ding, you consume 1,600 upgrade points to improve your scientific research base! The area of ​​the scientific research base has been increased from 300 square meters to 600 square meters!"

...

As the system prompt sound emerged, Chen Nuo took the elevator toward the third-floor scientific research base.

He really wants to know what new technology will be added to the scientific research base after the upgrade.

At this time, the space in the scientific research base was more spacious, and many robotic arms and production tables were added.

Chen Nuo didn't think much about this and asked directly:

"Scientific research, what are the new craftable technologies you have added?"

As soon as the words were finished, a detailed description of the new technology appeared on the center console.

Fighter: A fighter that can fire bullets and missiles, but also electromagnetic guns.

Materials required for production: one thousand kilograms of iron, one hundred kilograms of copper, and fifty energy crystals!

Speed ​​Shoes: Lightweight and durable, and after turning on the switch after the heel, you can fly with a speed of 100 meters per second!

Production requires: five kilograms of silk, one kilogram of copper, one kilogram of iron, and five energy crystals!

Advanced mines: The power of the explosion is no less than that of a single shot of a tank-fired shell!

It takes fifty kilograms of gunpowder, ten kilograms of iron, and an energy crystal!

Electromagnetic cannon: evolved from Barrett, a cannon that can emit electromagnetic beams, with a power comparable to a small missile!

Production requires: ten kilograms of iron and twenty energy crystals!

...

Almost all the materials required by the newly added technology use energy crystals.

It can be seen from this that energy crystal is one of the important materials for scientific research base production technology.

However, it is worth mentioning that the updated technology this time made Chen Nuo very curious.

This speed shoe helps escape and can be listed as a production list.

As for fighter jets, this one has more electromagnetic guns than modern fighter jets, and it is very powerful. Although you can't fly the plane yourself, you can consider this.

As for electromagnetic cannons, this is also good, it can attack enemies from a distance, especially with a very high power.

Chen Nuo didn't consider the last high-level landmine.

Although the power is very good, Chen Nuo himself dared not walk with peace of mind if he installed this thing.

While analyzing secretly, Chen Nuo thought of something, suddenly raised his head and his eyes shone.

"By the way, although I can't fly a plane, I have the spark of life..." Chen Nuo couldn't help but smile while pondering.

Yes, he can use the spark of life to give life to the fighter made.

In this way, there is no need to control it yourself.

Moreover, the fighter jet has weapons on its own. If given to life, it will inevitably become a Transformer with strong attack power.

Of course, in addition to fighter jets, Chen Nuo can also make a tank.

Finally, the tank is also given the fire of life.

In this way, he can create several powerful subordinates!

Thinking of this, he immediately asked:

"Scientific research, can current materials be used to make tanks and fighter jets?"

"Yes!" The scientific research answered very quickly.

"How many can I make?" Chen Nuo asked hurriedly.

"Four, but after making, the materials in the material warehouse will no longer support production!" Scientific research replied, and at the end of the conversation, his tone seemed a little regretful.

Hearing this, the smile on Chen Nuo's face couldn't help but disappear.

"It seems that the materials are a flaw. When this disaster is over, we must get more materials." Chen Nuo pondered in secret, and immediately ordered:

“Make it.”

After saying that, as the robot arm operated, Chen Nuo said again:

“How long will it take to make it?”

"Two days!"

Upon hearing this, Chen Nuo nodded and said nothing.

Two days, the system said that the end of this wave of disaster will be two days later.

"It seems that these two days are destined to be a bit boring." After muttering, Chen Nuo first brought a hundred talent pills, and then took the elevator to the fifth floor.

He plans to enter the retreat room where the concentration of spiritual energy is increased to 45% to practice.

After all, being strong is what you are.

Moreover, he still doesn't know what disasters will happen next, so what he has to do now is to become stronger.
