The end of the world: Start with a gun and build a tank in ten days

The second-level mutant giant turtle was frightened and wanted to turn its head.

But, it's still too late.

Just listen to a "bang" sound,

The death missile has arrived quietly.

Almost instantly, the head of the second-order mutant giant turtle was blown to pieces.

The extremely hard turtle shell had a crack visible to the naked eye.

Split from head to tail.

The blood immediately stained the sea area red, and the meat scraps floated on the sea surface, which was extremely fishy.

"Tsk, tsk,"

Lin Nan couldn't help but admire,

"This is really quite powerful!"

"Hey, what is this?"

He saw a green crystal being hit by the waves to the shore.

At the same time, a bright light flashed and the giant turtle's body disappeared.

Immediately afterwards, a second-level mutated giant turtle shell appeared in the system inventory.

"Ding, congratulations to the host for completing the mission."

After the plane landed, Lin Nan walked to the beach, gently picked up the green crystal and looked at it carefully.

Hearing the sound of the mission being completed, Lin Nan said,

"That means I can synthesize a RV!"

"Reporting to the host, a second-level evolution crystal is needed to synthesize the D-class RV fortress."

"Is there a second level of evolutionary crystal?"

Lin Nan glanced at the green crystal in his hand.

Not surprisingly, this should have exploded from the body of the second-order mutant giant turtle. Could it be the second-order evolutionary crystal?

The system seemed to see Lin Nan's doubts, so it said,

"The item in the host's hand is the second-level evolutionary crystal."

It’s true!

Lin Nan was stunned for a moment.

"It's actually a second-order one. Isn't it very valuable?"

Lin Nan already regretted synthesizing the RV, which meant consuming the second-order crystal, but there was no other way to do it without synthesizing it.

In the end, Lin Nan compromised.

"Take it and join the car!"

Lin Nan reluctantly gave up her love. At this moment, out of the corner of his eye, he saw that Chu Mengyao was still beside him.

The little girl's pretty face turned red.

"Don't you want to go to the toilet?

What are you doing standing here? "

"Brother, look around here. Is there any place where I can go to the toilet?"

Hearing the sound, Lin Nan looked around.

It's a vast white beach and there really is no place to go to the toilet.

Suddenly, Lin Nan thought that she owned a RV!

There must be a toilet in the RV!

At this time, the RV has been successfully synthesized.

A flash of light flashed, and a huge RV suddenly appeared in front of them.

Under the sunlight, the pure white metal body shines with dazzling luster!

"This is...an RV?

Wow! "

When Chu Mengyao saw this car, she was instantly excited.

Can't wait to open the car door.

"Don't come in yet!"

Chu Mengyao warned Lin Nan.

Lin Nan was confused, but after thinking about it, he understood what the little girl meant.

"well--

I spent a second-level crystal on this piece of shit! "

Lin Nan leaned against the car and opened the system's inventory.

He suddenly discovered that there were 100 first-level evolution crystals in the inventory at some point.

What surprised him the most was that there were two second-level green crystals.

"Did Spider-Man collect this before?"

Summoning the little spider, he took a look at his empty storage room and found that it was exactly what he expected.

"Good guy, there are more than 100!"

Lin Nan never dreamed that there would be so many!

What are you waiting for?

"The system will upgrade the system level for me!

Upgrade attribute points!

So many crystals should be enough, right? ! "

"Ding, congratulations to the host for successfully adding points!

Congratulations to the host for obtaining the physical active skill ‘Healing Light’.

Releases light that can heal wounds, consuming 2 points.

Congratulations to the host for obtaining the speed-based active skill ‘Afterimage’.

Using skills can create a person who is the same as the user to appear and confuse the enemy, consuming 2 points.

Congratulations to the host for obtaining the spiritual passive skill ‘Spiritual Armor’.

Can resist mental attacks to a certain extent, consuming 2 points. "

"It's really beyond my surprise to directly obtain three skills at once, but..."

Lin Nan opened the properties panel.

Host: Lin Nan

System order: second order

Strength: 20

Constitution: 20

Speed: 20

Spirit: 20

Evolution crystal: 78 (first level) 2 (second level)

"Why are there so many first-level evolution crystals left!

Also, why hasn’t the system level improved? !

Attribute points don’t increase either.

Aren't these crystals enough? "

"Report to the host that you are at the second level. The first-level evolution crystal can only supplement the points required for the first-level attributes, but cannot add points for the second-level attributes.

At the same time, adding points and upgrading require second-level evolution crystals! "

After hearing what the system said, Lin Nan was stunned.

"In other words, these first-level crystals are useless. In the future, you can only use second-level crystals for additional points and upgrades!"

"Exactly!"

"I wipe..."

Lin Nan was confused.

Does this even work? ? ?

"I knew how it could be so easy,

The most evil system is worse than Mahuateng! "

"How many second-level evolutionary crystals are needed to upgrade to the third level?"

Lin Nan gritted his teeth and asked.

The answer is, "100!"

In other words, Lin Nan wants to kill 100 second-level monsters!

Not to mention how difficult it is, just looking for it is difficult. After all, first-order zombies are the mainstream now.

"Also remind the host that there are still 10 days until the next overall evolution!"

“Still evolving???

Be good..."

Lin Nan looked at the mutant birds flying in the sky and the giant beasts looming in the sea. If they evolve again, it will really be the end of mankind!

→

This is to exterminate the human race!

"No, I can't wait any longer. I have to collect some second-level crystals quickly. Improving my strength is the most important thing now!"

In fact, after owning the fighter plane, Lin Nan thought of finding a quiet island far away from the hustle and bustle, where he could live out his life.

But now it seems that this dream may not come true.

Not to mention whether the giant monster in the sea will crawl to the shore, all evolution is forcing Lin Nan to grow.

Once he slows down and is overtaken by most monsters, he will really have to live a life of hiding everywhere.

"Now that my strength is above the mainstream strength, I must seize the time to improve!"

Just then, the door to the RV opened.

After settling her personal matters, Chu Mengyao was obviously much more relaxed.

"Brother Nan, how come you have such a nice RV? I have always had a dream to own an RV and then travel around the world and see the whole world!"

"Brother is sent by God to help you fulfill your wish, but now there is nothing to see except zombies. Let's improve our strength first!"

"Yeah, yeah, yeah!"

Chu Mengyao nodded obediently.

"Brother, what is this?"

She noticed the second-order green crystal in Lin Nan's hand, which was specially left for her by Lin Nan.

"Look, do you feel anything?" Lin Nan asked.

He just asked the system, how can a first-order evolver evolve into a second-order evolution?

The system's reply is to continue swallowing crystals, but the higher the level, the better. You have to act according to your ability.

Generally, first-level evolvers must be extra careful when swallowing first-level evolutionary crystals.

Once you feel resistant to the evolution crystal, you should give up.

Because that may be the limit of the body.

This is why Lin Nan showed it to Chu Mengyao and asked her how she felt?

Chu Mengyao took it and put it in the palm of her hand, looking at it carefully with her eyes still.

"What does it feel like?"

Lin Nan asked again.

Chu Mengyao raised her little head and smiled,

"Brother, please don't laugh at me if I say something?"

Lin Nan was stunned for a moment.

"Why would I laugh at you?

Tell me, how does it feel? "

Chu Mengyao said embarrassedly,

"I think...I want to eat it!"

Lin Nan was stunned again. Instead of resisting, he wanted to eat it.

Seeing Lin Nan's confused look, Chu Mengyao quickly explained,

"I said this because I saw that this thing is even more tempting than the ones I swallowed yesterday!"

"Then...do you want to eat?"

"think!"

Chu Mengyao said decisively.

“Then let’s eat it for you!”

With Lin Nan's permission, Chu Mengyao turned around and swallowed it in one gulp.

Then a look of contentment appeared on her face.

"How does it feel?"

Chu Mengyao narrowed her eyes and laughed,

"I still want it!"

“Still want it???

Darling, this is a second-order crystal!

It’s okay to just swallow it if you want to, but if you still want to swallow it after swallowing, that’s too much! Lin Nan thought in his mind, but he took out another one.

This is the only one he has left!

"Then look at it and see if you feel any resistance. Don't lie to me!

Once you feel you don't want to eat, don't eat. Eating forcefully will kill you! "

Chu Mengyao listened carefully to Lin Nan's words, pondered for two seconds as if feeling her body, then nodded heavily and said,

"No discomfort, I really want to eat it!"

Now that she said so, Lin Nan had no choice but to hand the last one to her.

Seeing Chu Mengyao happily taking it and swallowing it without thinking, Lin Nan's face turned green.

She is now considered to be at the peak of the first level, but Lin Nan feels incredible that she swallows the second level evolutionary crystal so casually.

After swallowing, Chu Mengyao looked satisfied again.

Lin Nan looked at him and couldn't help but want to ask,

"Do you still want it?"

As a result, Chu Mengyao nodded,

"want!"

"I wipe..." Lin Nan couldn't believe it and quickly asked the system for help.

"Is the system... normal?"

"Not normal!"

Lin Nan wanted to ask for some comfort, but he was shocked by the system's words.

But the system then said,

"Second-order evolver Chu Mengyao's physical indicators are normal and there is no danger!"

"It's good that there's no danger!

no……

This is an upgrade! "

Lin Nan was shocked when he heard what the system called Chu Mengyao.

This second level is somewhat arbitrary!

"Brother, I want more!"

At this moment, the little girl's voice sounded again.

She was seen gently shaking Lin Nan's clothes, her pretty face was slightly red, and her voice was soft and waxy.

Looking at her appearance, Lin Nan shook his head helplessly.

"Yao Yao, don't be like this, my brother has been squeezed dry by you!

I can’t give it to you! "

"Is it really gone?"

Hearing Lin Nan's words, Chu Mengyao was a little disappointed, but she soon returned to normal.

"Since my brother is gone, Yaoyao won't eat anymore.

Yaoyao is not a glutton, I can make a living well! "

Lin Nan smiled, but the focus of his thinking was not here, but on the second-level evolutionary crystal.

Since the evolvers can upgrade their levels through evolution crystals, what about the monsters?

"System, how are the second-level mutants formed?"

"Evolved from the first level."

"..."

I know that too!

Lin Nan was speechless: "Then let me ask another way. What means can the first level be promoted to the second level?"

"One is to be promoted to the second level through the overall evolution!

The second is to devour the first-level evolution crystals. When a certain amount is accumulated, there is a chance to be promoted to the second level!"

Hearing the system's words, Lin Nan smiled evilly,

"Sure enough, it is also devouring the first-level evolution crystals!"

He glanced at the pile of first-level crystals in the inventory, and then said,

"Since second-level zombies are hard to find, I'll feed some second-level zombies!"
