With this tactic, the upgrade of the RV went surprisingly smoothly.

Ga!

The chain gun fires 650 explosive rounds per minute.

However, it was all bounced back by the scales of the hydra.

It's an incredible defense.

"What a strong defense! This one! ”

Chu Nan hurriedly stopped Clarys, who was about to fire more chain cannons.

"Don't shoot yet. Otherwise, it's a waste of bullets. ”

"What should I do, it's coming!"

"Ugh!"

Just as Claris finished shouting, the RV shuddered.

The hydra must have attacked the RV.

It was the collision of a nine-headed hydra that was 60 meters long and three meters thick, but the RV managed to pull it down.

The armor of an RV that reaches level 16 is a steel level 7m.

The reason why it has more defense than any fortress.

But.

The only on-board weapons on board the RV were the M2 heavy machine gun and chain gun.

That is, the maximum attack power is to shoot through 50mm of armor.

Its attack power is too low compared to its high defense.

"In that case, then bear with it!"

The current motorhome has a top speed of 360km/h.

And the acceleration power is 4.6 times that of the original, and the weight of the vehicle has increased to 200t.

With that kind of strength and speed, if you hit it several times in a row, even Hydra couldn't resist it.

Thinking so, Chu Nan hit the hydra at full speed with the RV.

！

1 time, 2 times, 3 times, 4 times, 5 times......

Whenever the RV hits, the hydra growls.

Looks like it will do some damage.

However, this is far from a fatal wound.

And every time he hits it, the hydra shoots back with flames from its mouth.

"Dry, I'm glad I got a heat-resistant temperature of 50,000 degrees."

Looking at the rocks that were directly hit by the flames spewed out by the hydra and melted into powder, Chu Nan couldn't help but sigh in his heart.

If it weren't for the fact that he had increased his stat defense, he would have been done with one blow.

However, it seems that even the heat-resistant temperature of 50,000 degrees is not perfect.

Little by little, the cracks in the body of the house melted.

"Eat! Really, it became a comparison of endurance. ”

Chu Nan continued to attack the hydra of the RV at full speed.

！

"Goo!"

After more than thirty strokes, the sound of the Hydra's bones breaking sounded, and the lower half of its body stopped moving from where the bones were broken.

"Alright, slow down! Next time, I'll hit it close to the head! ”

This time his target was changed to the bottom of the branch neck.

After thirty-four consecutive blows, the sound of bones breaking sounded.

"Phew, now it can't move. Now all I have to do is attack those nine immobile necks. Claris, please. ”

"Leave it to me!"

Claris shoots Hydra in the eyebrow with a chain gun.

But!

！

All the bullets bounced out.

"Ahh Is it so hard now? However, it can now be attacked with personal equipment. ”

"What should I do?"

"Attacking with Carl Gustaf"

Chu Nan ran into the sniper space and operated the monitor.

Carl Gustaf M3 recoilless gun

-- Caliber 84mm

-- Total length 1130mm

Weight 8.5mm

- Effective range: 700 meters (HEAT751 anti-tank grenades)

――1000 meters (HE441 high-explosive bomb)

- 500mm armor piercing

- Comes with 10 rounds of ammunition. Optional 441 grenades and arrow ammunition are also available.

Yes/No: Purchase

"Yes, of course."

Chu Nan nodded "yes", arranged the shells of Carl Gustav that appeared in the air on the shelf, carried it on his shoulder, and raised the sniper space, in the sniper space, there was only a hole about 10 cm in diameter, but it was okay.

"Come on, look at the big guy!"

Chunan aimed Carl Gustav at one of its necks and pulled the trigger.

！

The anti-tank grenade that was fired hit Hydra's head as expected.

！

He hit it in the head well.

500mm armor penetration is not blown!

"One more time!"

Chu Nan cheered and regained Carl Gustaf's position.

"Okay, just destroy the rest of your head."

In order to fight back against such Chu Nan, the hydra opened its mouth with one neck and spewed flames.

Dangerous!

The hydra's counterattack was faster than expected, and Chu Nan's cheeks twitched.

"I'm not going to give you a chance!"

Ga!

Claris shoots the hydra in the mouth with a chain gun, and the hydra opens its mouth and breathes fire.

“！”

The hydra screamed as it was shot through the mouth in the head, lost its strength, and fell to the ground.

Although it is a Hydra zombie, the defense of the mouth does not seem to be high.

"Well done, Claris!"

"Give me the support!"

Chunan shoots Carl Gustav away, and Claris opens his mouth to fight back with a chaingun aimed at its neck.

In this way, Chu Nan and Claris successfully defeated the Hydra.

"Wow, it was too dangerous just now."

After defeating Hydra, Chu Nan returned to the RV.

And replenish chain gun ammunition immediately after reloading.

--Defeat a zombie hydra.

- Experience 75000

- 75,000 skill points

- Accumulated experience points over 40,000.

And the results of the battle are displayed on a virtual panel on the monitor.

Bite!

Ding——!

The horn of the upgrade sounded, and every time he heard it, it excited him.

The armored vehicle level reached level 17.

- The top speed is now 390 km/h.

-- 10% increase in acceleration and 25% increase in damping force.

-- Climbing performance 82 degrees, vehicle weight 230 tons.

-- The armor level has been changed to 8.5 meters of steel.

-- Added AL chat system. (New)

- Added weapon enhancement skills. (New)

"Huh? The description just now seems to be different from usual? ”

As Chu Nan muttered to himself.

"Yes, the al chat system is working"

A mechanical voice rang out.

"Al chat system? How do you work? ”

"Advise the owner and suggest the best response in case of emergency."

"So, what is this weapon enhancement?"

"Since the armored car has reached level 17, it is now possible to strengthen weapons with skill points. The current RV attack power is insufficient, and it is recommended to upgrade the weapon. ”

After listening, Chu Nan tried to confirm.

“…… By the way, do you mean the AL chat system? ”

"That's right"

"That will help."

Claris pecked Chu Nan, who was muttering like this.

"Hey, Chu Nan, what's going on with this voice?"

"Huh? Ah, this, the car's navigation robot, can give advice. ”

"Really? That's really convenient, isn't it? ”

"Ah, yes, it seems to be a lot more convenient."

"Does that help me too!?"

The al chat system answered Claris, whose eyes lit up.

"I only talk to the owner."

"Huh~~? So boring. ”

Claris pursed her lips.

Such an expression was really cute, but anyway, he decided to ask him about his new abilities first.

"Hey, Al chat system, let's talk about weapon enhancements."

"At present, weapons can be strengthened up to level 7, which is a maximum of 30 times."

"Thirty times!? That's amazing! ”

The al chat system told Chu Nan mechanically.

"But skill points are needed"

"Well, yes, how much do you need?"

"Do you want to show the skill points required to strengthen 30 times?"

"Well, yes. Come on. ”

- Pistol (currently owned by Beretta, M500) 5900 (5900 skill points per cost)

- Rifle (currently has M16, Barrett M82) 11800 (11800 skill points per cost)

- Carl Gustaf 11800 (11800 skill points consumed each time)

- M2 Heavy Machine Gun 11800 (11800 skill points consumed each time)

- Chain Gun 29500 (29500 skill points consumed each time)

"Huh? The M2 Heavy Machine Gun consumes the same skill points as the M16. ”

"Yes, because it uses the same bullets as the personal weapon Barrett"

"Is there anything like this?"

"If you consume 42,300 here, you will only have 1,624 skill points."

The al chat system of the car navigation system made a suggestion to Chu Nan, who was muttering like this.

"If you value destructive power, you can buy Hellfire anti-tank missiles. Carl Gustaf shoots through 600mm armor, while AGM-114 anti-tank missiles shoot through 1350mm armor. ”

"The missiles are incredibly powerful."

"However, there are only four Hellfires that can be fired, and it will cost to use them again."

He understood.

The Hellfire, powerful enough to pierce 1.35 cm of armor, costs half as much as a chain gun, probably because it costs 5 skill points per 4 bullets fired.

By the way, the skill points required for enhancement seem to be the same as those for chain guns.

"The purchase of a tank turret is a way to do this, the armor-piercing capacity of a 120mm smoothbore gun mounted on a tank turret is 600mm, but its reload is 300 rounds."

He understood.

Since he can shoot 300 shots, does the tank turret need 20000 purchase points?

But what's the best way to do it?

Should twin machine guns and chain guns be strengthened?

Should he buy 4 Hellfires?

Or should he buy a tank turret?

If you think about the power of a single shot, it's Hellfire or a tank gun.

However, the rapid-fire power of the M2 heavy machine gun and chain gun is also unstoppable.

Thinking about various things, Chu Nan decided to strengthen the chain gun and the M2 heavy machine gun to the limit.

Temporarily upgrade the Chain Gun and M2 Heavy Machine Gun to earn XP without moving forward.

As you level up, you accumulate skill points needed to upgrade other weapons or buy new ones.

"Are you sure? That's only 1624 skill points left. ”

al chat system asked.

"It's okay, with this, I can easily defeat Hydra, and then for every Hydra defeated, I can get 7,500 skill points, and the money will be returned quickly."

！

The M2 heavy machine gun, which was strengthened 30 times, easily pierced the troublesome body of the Hydra and held it in place.

！

The 30 times more powerful chain gun easily wiped out the Hydra's head.

"Awesome! I can really beat Hydra with ease! ”

Chu Nan returned to Claris with a smile, and Claris jumped for joy after defeating the Hydra so hard.

"Great."

However, Chu Nan's face suddenly became gloomy.

"But with such powerful zombies, it means that the Heavenly Demon Holy Land itself also has more powerful zombies, right?"

The closer you get to the Heavenly Demon Holy Land, the stronger the zombies will be.

And now they haven't entered the Heavenly Demon Holy Land, which means that it is even more dangerous.

Maybe 10 Hydras or 11 Hydras or something like that.

Claris shook his head at the worried Chunan.

"No, I don't think there are zombies in the Holy Land, because that kind of powerful magic is not something that zombies who have lost their wisdom can control."

"It was, it was......"

For Chu Nan, who breathed a sigh of relief, Clarys added with an embarrassed expression.

"That's it, yes, but there may be other horrors besides zombies."

"Terror exists ......"

"Yes, more trouble than Hydra."

"But what the hell is the Holy Land?"

"I don't know the specifics, but according to legend, it is the magical place that maintains this world, and we have been guarding it for generations, and now it should be protected by the clansmen of the Guyin clan, about 10,000 people."

"Ten thousand!? So much? ”

It seems that the Heavenly Demon Holy Land is much bigger than Chu Nan imagined.

"Of course, and it's surrounded by walls, like a fortified city."

"I see."

"Yes, moreover, the Gu Yin clan should have been countered now, it's not clear for the time being."

"I see, how strong is that Gu Yin clan?"

"In the past, it was the strongest in magic, but it had almost no physical attack power, but now, it has become an immortal, and its combat power has been strengthened, which is about a hundred times that of ordinary humans."

"And what's even more troublesome is the high-level undead, whose combat strength is no less than that of the Hydra Zombie."

"Really? Do you know how many there are? ”

“…… I think there should be about a hundred in total.

"I see, the immortal of the upper-rank Gu Yin clan, who is stronger than the Hydra zombie, is really strong. And there are more than a hundred! ”

Buying a tank turret upgrade, he will also have unimaginable combat effectiveness, the armor piercing of the tank turret is said to be around 600mm, but the armor piercing of the Hellfire is 1350mm.

In terms of destructive power alone, it far exceeds the turret of a tank.

However, there is a disadvantage that if you shoot all four, you need to consume skill points and reload before you can use them.

However, considering the combat effectiveness of the undead of the High Ancient Yin Clan, it is better to buy tank guns and hellfire to strengthen them.

"That way, I can earn skills for the time being. …… AL chat system, is it possible? ”

The al chat system immediately answered Chu Nan's question without hesitation.

"yes, I'm sure it's going to be a tough fight, so I think it's better to increase my attack power as well."

He has enough skill points to buy a tank turret and 4 Hellfire.

So his goal is to earn 59,000 skill points, which are necessary to strengthen the tank turret and 4 Hellfires he bought.

In the process, the RV will also be upgraded several times over, and its defense will also increase.

"Well, even the Hydra is easy to take down anyway, so I'll knock down all the Hydras I find."

"Roger!"

The AI chat system answered.

He drove the car and continued to set off.

Killed during the period:

- 24 six-headed hydra zombies.

- 11 seven-headed hydra zombies.

- Seven eight-headed hydra zombies.

- Three Hydra zombies.

As a result, the accumulated experience points exceeded 130,000, and the top speed of the motorhome upgraded to level 21 was increased to 510 km/h, and the acceleration force was increased by 7.4 times.

The climbing performance is 90 degrees, and the vehicle weight is 360 tons.

But under normal circumstances, no matter how powerful the engine is, a 360-ton vehicle cannot accelerate to a speed of 510 kilometers per hour.

This is because the tires are spinning.

Moreover, a wall with a 90-degree angle, that is, a vertical wall, cannot be climbed.

In other words, the performance of the current RV has reached a level beyond common sense.

The armor has also become as strong as 76 meters of steel.

It's a power that even nuclear weapons can withstand.

At least in terms of defense alone, isn't it the strongest in the world?

However, the minimum skill points required every day are 1 full oil, 1 consumable recovery, and 2 room cleaning instead of laundry, a total of 4.

20 Level 5 medical treatments that can heal any serious injury.

Positioning that can be restored even if the RV overturns.

If so, it's time to move on.

"Then I want to buy a tank turret and 4 Hellfires."

"Spend skill points to buy a tank turret and 4 Golems"

At the same time as the decision was made to buy, the virtual display panel on the car's navigation system showed a map of the motorhome, a tank turret and four Hellfires.

"Well, where should I put it?"

Worried, he decided to temporarily use ordinary tanks as a base.

After all, the current tank styling is the result of trial and error.

"In the center of the RV there is a tank turret, and on the left and right sides of the tank gun are set up missile compartments with two Hellfires."

The al chat system asked Chu Nan.

"Four missile bays in a group that requires 1000 skill points to divide into 2 units."

"Oh, I don't mind that much"

"Okay."

Next up is weapon enhancement.

"Can you push the tank turret and Hellfire to the limit?"

"No problem."

Combat readiness is now complete.

"Okay, Claris, then let's go to the Heavenly Demon Holy Land."

"Yes!"

Hearing Chu Nan's words, Claris nodded resolutely.

"I see, it's definitely a strong city."

Chu Nan muttered to himself on a small hill overlooking the Heavenly Demon Holy Land in the distance.

The walls are 20 meters high and 3 meters thick, surrounding beautiful streets reminiscent of medieval Europe.

The diameter of the city wall surrounding the city is about one kilometer, and the magic array with a diameter of fifty meters in the center is estimated to be the magic array that has become the Holy Land of the Heavenly Demons.

"Although it is a thick wall, if the RV rushes over, it will be breached."

Claris smiled sneerably at Chu Nan, who had leaked his impression.

"And you're just squeezing in?"

"I, I don't want to destroy the Heavenly Demon Holy Land, it will take a lot of time and money to rebuild it."

Hearing Chu Nan's words, Claris showed a surprised expression.

"It's easy to build a city this big."

"Is that so!?"

Claris chuckled at Chu Nan's wide-open eyes.

"Yes."

“…… It's remarkable. ”

Claris once said that she would buy the shower toilet with the RV for 100 kilograms of gold, but if the fortified city could be easily rebuilt, then 100 kilograms of gold would be insignificant.

"Then you don't have to put up with it."

Claris hurriedly added to the grinning Chunan.

"Ah, but don't destroy the magic array in front of you! I'll tell you when the time comes. ”

"I understand."

If it's just a zombie, the RV can run over and kill it.

However, a high-level immortal with 100 times the combat power of a human being can easily pounce on the body of the RV.

And RVs also have blind spots where their onboard weapons can't attack.

The RV won't be destroyed, but if they can't attack from here, they'll be in a stalemate.

"It's best to attack from a distance, Claris. As long as the magic array is safe, the fortress city will be fine, right? ”

"yes. Like I said, it's easy to rebuild. ”

Chunan moved the RV to ten kilometers from the Dracul Sanctuary and nodded to Clarys, who said it would be easy.

The road to the Sanctuary of Delacour is only distributed on the left and right sides of the site, so the prospect is very good.

The M2 heavy machine gun has an effective firing range of 2000 meters and a maximum range of 6770 meters.

The M2 heavy machine gun was strengthened 30 times.

No matter how big the enemy is, you can defeat it before you reach the RV.

The M2 heavy machine gun can also be fired at a time.

It is a mistake to think that the word machine gun can only shoot continuously.

"Okay!"

"There are high-ranking immortals of the Gu Yin clan patrolling the city wall."

Claris whispered while wearing the headphones used by Chu Nan.

"So, first of all, try to minimize the enemies in your line of sight."

Chu Nan nodded earnestly at Claris, who was reaching for the M2 heavy machine gun controller.

"Hmm."

"Roger!"

！

"Goo-ha!"

The bullets fired from the M.2 heavy machine gun devoured the high-ranking undead and splattered in all directions.

However, even if it is a high-level undead, its defense is very high, and its combat power is more than a hundred times that of humans.

However, the M2 heavy machine gun wiped out the high-level undead with just one shot.

It's only thirty times stronger, and it's ridiculously destructive.

However, Chu Nan noticed a strange phenomenon there.

“…… Wait a minute, how did you hear the screams of the high-ranking undead who were shot? ”

The RV was parked ten kilometers from the city walls.

How could he hear so far away?

Then, the voice of the AL chat system sounded:

"The M2 heavy machine gun, chain gun, and tank turret are equipped with sound collectors to obtain information. With this, the sound can be heard when zooming. ”

"Fantastic"

Chu Nan thought so from the bottom of his heart.
