Start the game with ten thousand times return, build a god-level shelter!

Now that he has more than 10,000 return points in his hand, he can finally use it without picking and searching like before.

His upgrade focus is still on weapon systems.

As for the other aspects, if there is a surplus at the return point, let's look at it.

The weapon system is in the shelter, a separate section.

At present, the gun-making line and the bullet production line have been activated.

Lin Cheng opens the system panel.

At this moment, there are more inactive content in the weapon systems section.

[Howitzer production line: not activated].

【Activation condition: 10,000 return points】

[Activation function: 10 howitzers can be made per day].

......

[Armored vehicle production line: not activated].

[Activation condition: 50000 return points].

[Activation function: 5 armored vehicles can be made per day].

......

[Self-propelled gun line: not activated].

【Activation condition: 100,000 return points】

[Activation function: 2 self-propelled guns can be made per day].

......

The back is in an unlocked state, and Lin Cheng can't see any heavy firearms.

However, it can be calculated from the weapon to be activated.

These things are not very powerful.

"System, upgrade the gun production line for me!"

[Okay, host, the gun production line has been upgraded successfully! ] 】

[Firearms production line: 100 pistols, or 25 rifles, or 10 light machine guns, or 5 heavy machine guns can be produced every day! ] 】

[Consume 1000 return points, return point balance 12300 points! ] 】

Do you want to continue upgrading?] 】

"Go on!"

【Gun production line upgrade successful! 】 】

[Firearms production line: can produce 600 pistols per day, or 150 rifles, or 60 light machine guns, or 30 heavy machine guns! ] 】

[2,000 points of consumption return points, 10,300 points of return point balance! ] 】

Do you want to continue upgrading?] 】

Lin Cheng calculated and followed this progress.

After 8 days, he would have a thousand guns.

This size is enough to equip a regiment.

"Enough, arrange a production line of firearms, according to the order of pistols, rifles, light machine guns, heavy machine guns, 1000 of each!"

[Yes, the host, the gun production line has started production according to the host's requirements. 】

......

"Now upgrade the bullet production line."

[Okay, host, bullet production line upgrade successful! ] 】

[Bullet production line: can produce 50,000 rounds of pistol bullets, or 30,000 rounds of rifle bullets, or 15,000 rounds of light machine gun bullets, or 10,000 rounds of heavy machine gun bullets per day. 】

[Consumption return points 3000 points, return point balance 7300 points! ] 】

Do you want to continue upgrading?] 】

"No need to upgrade. Production was carried out in the order of production of bullets for heavy machine guns, light machine guns, rifles and pistols, with 100,000 rounds for each type of ammunition, followed by the first three. "

[Okay, host, it's already arranged. 】

[Remind the host that neither the shelter power system nor the generator set prepared by the host can support the corresponding power consumption.] 】

【Please upgrade the power system immediately! 】 】

Lin Cheng thought about it too.

The production of firearms and bullets is a major consumer of electricity.

So he spent 2,000 return points to upgrade the power system to level 5.

It can provide 50,000 kWh of electricity per day.

This power, even if some more power-consuming equipment is added, it is enough.

......

After calculation, Lin Cheng still has 5,300 return points that have not been used up.

At present, the industrial park is still under construction, and it is not convenient to upgrade the size of the shelter.

Lin Cheng first placed an upgrade in the area of the shelter.

The shelter is located in the middle part of the entire industrial park.

Lin Cheng also asked the infrastructure robot to temporarily retain the building outside the shelter.

The shelter was also covered with camouflage cloth, making it impossible to see that it was a shelter.

At the same time, the construction of the entire industrial park could not reach the vicinity of the shelter.

Lin Cheng emphatically stressed that no one was allowed to come here.

A whole team of robots patrols back and forth 24 hours a day.

Therefore, the shelter will never be discovered.

Since he couldn't upgrade the area at present, he simply upgraded the shelter material.

"System, upgrade the shelter material!"

[Okay, host, the shelter material has been upgraded to grade 2, 80 cm thick ordinary alloy steel! ] 】

[500 points for consumption and 4800 points for remaining points!] 】

Do you want to continue upgrading?] 】

"Go on!"

【The material of the shelter has been upgraded to grade 3, 80 cm thick tungsten titanium alloy steel! 】 】

[800 points of consumption return points, 4000 points of remaining return points! ] 】

Do you want to continue upgrading?] 】

"Don't upgrade yet."

80 cm thick special tungsten titanium alloy steel!

Even top-level military installations cannot reach this level of security!

Tungsten titanium alloy, as the hardest material, is only 10 cm thick and can withstand the attack of tank shells.

50 cm thick tungsten titanium alloy, even the ground drilling bomb is helpless!

Now the 80 cm thick tungsten-titanium alloy steel shelter in Lincheng.

It can be said that it is the strongest place in the world at the moment.

Even if hundreds of tanks or tens of thousands of zombies came, they could not cause any damage to the shelter.

With this level of protection, Lin Cheng was finally completely relieved in terms of safety!

There are 4000 return points left.

Lin Cheng spent 2,000 return points to activate the monitoring center, which can monitor the entire range of the shelter within a radius of 200 meters.

"There are 2,000 more points..."

Lin Cheng thought for a while and spoke: "System, upgrade the robot manufacturing center!" "

[Okay, host, robot manufacturing center upgraded to level 2, can make 40 primary robots per day].

[Consumption return points 2000 points, balance 0 points, can not continue to upgrade.] 】

[Ask the host to select the primary robot attribute.] 】

At present, Lincheng already has 150 primary infrastructure robots.

These robots are more than enough to handle the work at this stage.

"According to the order of infrastructure, combat, medical, reconnaissance, mechanics, etc., 200 pieces of each category will be produced first!"
