"System, isn't the divine talent already the highest talent? Why is my cultivation so slow after reaching the immortal talent?" Chen Nuo was a little anxious.

After all, these people have become stronger after this wave of spiritual energy revival.

Some people even have the strength comparable to the fifth level of the Body Refining Realm.

How can this make Chen Nuo not anxious?

"Ding, practice requires three points: one, talent, two, the level of spiritual energy, three, practice skills!"

"In addition, because the earth's spiritual energy was extremely rich, even though the spiritual energy concentration in the retreat room was extremely high, the purity was not high, which led to the host's cultivation speed being extremely slow. I believe the host could feel this yesterday."

The system's answer is very detailed.

When Chen Nuo heard this, he couldn't help but nod.

Indeed, the feeling of practicing yesterday was completely different from the previous few days. With the systematic explanation, Chen Nuo instantly understood the reason.

"It seems that spiritual energy is not only divided into concentration, but also purity." He analyzed secretly, only feeling that his knowledge had increased.

"So, what if I practice again now?" He asked quickly.

"It will rise to the top!" Chen Nuo's eyes lit up with a pity for his words.

really!

Same as you think!

"There are more than 200,000 upgrade points..." Thinking of this, Chen Nuo couldn't help but make a decision.

"Tomorrow is the day when the fourth wave of disasters comes. I don't know what this disaster will be like..." Chen Nuo thought to himself and gave up the idea of ​​continuing to practice.

"System, can you unlock the magical powers and weapons of the mall by upgrading the shelter to level 15?" Chen Nuo asked when he thought of something.

After all, among the basic cultivation knowledge I learned at that time, weapons and supernatural powers were very powerful things.

Among them, if the weapon is powerful to a certain extent, and even has powerful weapon spirits, it can destroy the world.

Not to mention supernatural powers, name means meaning!

Therefore, Chen Nuo wanted to upgrade the shelter level, one was to enhance the shelter, and the other was to learn magical powers and purchase weapons.

"Yes!"

Upon hearing this, Chen Nuo asked again:

"So, if I upgrade to level 15, how many upgrade points do I need?"

“713800 points!”

"More than 700,000?" As the system answered, Chen Nuo couldn't help but take a breath of air conditioning.

"Forget it... wait a while before upgrading." Chen Nuo backed down.

"By the way, how many upgrade points are needed to upgrade the retreat room?" Chen Nuo asked when he thought of something.

“329600 upgrade points.”

Upon hearing this, Chen Nuo's expression was inevitably a little subtle.

It can't be upgraded.

Sure enough, the more you go to the future, the harder you can improve, just like practicing.

"So, how many upgrade points are needed to upgrade the scientific research base again?" Chen Nuo said again.

“12800 points!”

"What new technology will be added after the upgrade?" Chen Nuo asked after hearing this.

"Scientific research base, upgrading to level 10 requires 12,800 upgrade points, and new technology can be added: Mechanical armor (new flight devices and enhanced defense.) Atomic bombs, hydrogen bombs!"

Upon hearing this, Chen Nog's eyes widened.

Hiss...

"It's all good things! Upgrade!" Chen Nuo immediately ordered the upgrade without thinking much.

"Ding, you consume 12,800 upgrade points to upgrade the scientific research base, and the scientific research base has added a new enhanced version of mechanical armor, atomic bombs, and hydrogen bombs!"

As the system prompt sound appeared, Chen Nuo followed suit and headed towards the scientific research base.

"Although the power of atomic bombs and hydrogen bombs is very powerful, they are very dynamic and not as good as electromagnetic cannons. However, the enhanced version of mechanical armor is very heart-warming."

Chen Nuo thought to himself as he walked.

At the same time, he has also arrived at the scientific research base.

"Scientific research, bring out the new craftable technology." Chen Nuo directly ordered without any unnecessary nonsense.

As soon as he finished speaking, a light curtain appeared on the center console:

"Mechanical Armor: It has a flying device, is light-fitting, and can defend against attacks from bullets, cannons and even missiles!"

Production requires: fifty kilograms of black iron, ten kilograms of copper, and one hundred energy crystals!

"Atomic bomb: the effective killing area of ​​a 100,000-ton atomic bomb is 33 square kilometers, the effective killing area of ​​a 1 million ton atomic bomb is 150 square kilometers, the effective killing area of ​​a 10 million ton atomic bomb is 700 square kilometers, and the effective killing area of ​​a 100 million ton atomic bomb is 3,200 square kilometers."

Production requires: 10,000 tons of iron, 90,000 tons of gunpowder, 1 million tons of 10,000 tons of iron, 900,000 tons of gunpowder, 10 million tons of iron, 10 million tons of gunpowder, 10 million tons of iron, 9 million tons of gunpowder.

"Hydrogen bomb: The more materials you use, the stronger your power will be, and the power will not be limited!"

Making materials: iron, gunpowder.

...

"The materials of the atomic bomb are at least in tens of thousands..." Chen Nuo's face was a little low.

Too expensive...

"The electromagnetic cannon is more fragrant." After thinking about it, Chen Nuo looked at the mechanical armor.

"This is a mecha similar to Iron Man. People can't recognize me after putting it on, and their defense is also very touching." During the analysis, Chen Nuo did not think much and directly ordered:

"Scientific research, make this mechanical armor!"

He noticed this before, but it was not a special need at that time, so he didn't think much about it.

At this moment, with Chen Nuo's analysis, the robotic arm in the scientific research base started to operate.

"Okay! The production time is one day!" This time, Scientific Research cleverly told Chen Nuo the time of production.

Hearing this, Chen Nuo nodded, then turned around and left here.

At this time, the scientific research base is very busy.

It not only needs to create dark metal to install it on fighter 1 and others, but also to make mechanical armor for Chen Nuo.

...

"I'm basically not afraid after I go out, but I lack some good weapons." Chen Nuo, who came to the living room, couldn't help but ponder.

Although the light knife I use is very good now, he always feels that it is not particularly good.

I looked at the time point of 15:54.

Chen Nuo asked: "System, how many upgrade points are needed to upgrade the shelter?"

Because he still has about 200,000 upgrade points now.

Therefore, he always felt that he should use the applicable places.

“102400 points!”

"It's a little over 100,000...Prepare it, choose to expand the area around it!" Chen Nuo hesitated for a moment and then ordered.

"Ding, you consume 100,000,2400 upgrade points to improve the shelter level, the shelter level is upgraded to level 13, the shelter area is upgraded from 12,800 square meters to 25,600 square meters! The thickness of the invisible door has been increased from 60 centimeters to 65 centimeters, and the surrounding walls have been increased from 60 centimeters to 65 centimeters! "

Upon hearing this, the area of ​​the entire shelter expanded instantly.

In a moment, the vision expanded a lot.
Chapter completed!
