Global Catastrophe: Get a 1000-acre survival base at the start

Su Yuan raised his hand, and used a laser gun to shoot four or five times at the drone equipped with a high-definition camera.

After dodging two or three shots, the drone was hit by a laser and fell.

Immediately, the other two drones shot at Su Yuan.

The two drones were modified with small automatic machine guns capable of firing 100 rounds.

The bullet hit the protective mechanical exoskeleton on Su Yuan's body, and sparks flew everywhere.

Although Su Yuan couldn't be hurt, the huge force also pushed Su Yuan back again and again.

Su Yuan picked up the laser gun and shot at the two drones.

Two minutes later, the two drones were shot down by Su Yuan.

The protective mechanical exoskeleton on Su Yuan's body was also damaged and needed repairs.

After picking up the wreckage of the three drones, Su Yuan found that one of them was well preserved, and the other two had been scrapped.

"Master, this ordinary drone can be repaired by the automatic maintenance machine house. After repairing, the master can also upgrade it!"

This idea is good, Su Yuan took the unmanned aerial vehicle that was still in good condition and put it into the automatic maintenance machine room.

After closing the door of the maintenance room, I saw a series of mechanical arms repairing and modifying the drones in an orderly manner.

Repairing and transforming drones does not need to consume survival points, but only consumes some electricity.

If you want to transform it into something, you only need Su Yuan to tell Xiaoyu the idea, and Xiaoyu can automatically repair the machine house through system control.

More than half an hour later, the drone was successfully repaired and transformed, and it was still a very ordinary reconnaissance drone.

Ding, it is detected that the host has seized a drone, do you choose to recycle it or upgrade it?
Su Yuan didn't want to recycle, but he wanted to know the price of recycling.

"Xiaoyu, how many survival points can I get by recovering this drone?"

"Master, 3 survival points!"

"I want to upgrade!" Su Yuan said silently in his heart.

Ding, to upgrade to a multi-functional drone, you need 30 survival points, do you want to upgrade?

"upgrade!"

Ding, the upgrade was successful.

[Multifunctional unmanned reconnaissance aircraft, fully charged can cruise 100 kilometers, the maximum flight altitude is 1000 meters, and the maximum reconnaissance range is 10 square kilometers. 】

[Upgrade to level 1 of automatic drones, 500 million survival points, and can conduct autonomous reconnaissance! 】

"Continue to upgrade!"

[Automatic drone level 1, fully charged can cruise 200 kilometers, the maximum flight altitude is 1100 meters, and the maximum reconnaissance range is 15 square kilometers. 】

[Upgrade to level 2 of automatic drones, 1000 million survival points, and can receive detection radar signals! 】

Detecting radar signals?Perhaps the radar signature of the surrounding private bases can be monitored.

Su Yuan finally decided to upgrade the automatic drone to level 2 and bind it to the system.

"Xiaoyu, from now on, when the food planting starts during the day, you will use the automatic drone to scout the surrounding situation. If there are any strange beasts or other production bases that invade, please notify me at any time!"

"Master, don't worry, as long as there is an abnormal situation, I will report to the master at any time!"

Then Su Yuan took the attitude of giving it a try, carried the wreckage of the other two drones into the maintenance room, and let the maintenance machine be disassembled and assembled to see if he could assemble a useful drone.

After a while, Xiaoyu received a message to automatically repair the machine house.

"Master, the automatic maintenance machine house said that an attack drone can be assembled, but it lacks attack weapons!"

"Is the laser gun okay?" Su Yuan said.

"Yes, the laser gun can completely deal with ordinary beasts or ordinary drones!"

Then Su Yuan spent another 1000 million survival points to buy a laser gun, assemble it on the drone, and upgrade the attack drone to level 2 of the automatic drone.

[Automatic drone level 2 - attack type: fully charged can cruise 200 kilometers, the maximum flight altitude is 1100 meters, the maximum attack range is 500 meters, and the number of attacks can be 300 times. 】

Su Yuan was pleasantly surprised to find that the laser gun was assembled on the drone and was upgraded along with the drone, increasing the number of times it could be fired.

On the other hand, instant noodles have also harvested all the mature soybeans. Although the production has been reduced a lot, Su Yuan still earned more than 6000 million survival points today.

After deducting the survival points for purchasing upgraded chicken coops, laser guns and upgraded drones, Su Yuan still has more than 2.1 million survival points in his hands.

It's still a while before it gets dark, but the temperature is already dropping rapidly.

Su Yuan came to the steel fence that was bitten by pigs and rats.

Think of the steel fence in my heart.

Ding, the steel fence is damaged, and 3 survival points are needed to repair it. Do you want to repair it?

"repair!"

Ding, the repair is successful, you can upgrade to level 2 steel fence, you need 50 survival points, do you want to upgrade!

"upgrade!"

Ding, the upgrade is successful, you can...

"Continue to upgrade!"

Su Yuan spent another 3500 million yuan to upgrade the steel fence from level 1 to the steel city wall.

[Steel city wall level 1: 10 meters high, 3 meters thick, buried 3 meters deep underground, 7 meters above the ground, can withstand the impact of ordinary level 9 alien beasts! 】

[Upgrade to level 2 of the steel city wall, 2000 million survival points, 12 meters high, 4 meters thick, buried 3 meters deep underground, containing 10% titanium alloy, can resist aggression level: level 1 alien beast impact! 】

Aggressive level?
Because the most powerful beast Su Yuan has seen so far is the Ma Ying.

As for the aggressive-level alien beasts, I have only heard of them in T Company. It is said that even shells can't kill the aggressive-level alien beasts, and seven or eight aggressive-level alien beasts can destroy a survival base.

So Su Yuan felt that Level 1 of the Steel City Wall is enough for now, and there is no need to upgrade to Level 2 for now.

Most importantly, three drones suddenly appeared today, waking up Su Yuan.

He felt that it was necessary to install a dome so that the drone would not be able to find out what was going on in his survival base by flying overhead.

To install a dome, and to cover a thousand acres, the ordinary dome is definitely not strong.

Su Yuan gritted his teeth and spent 1.5 million survival points to buy a titanium alloy automatic dome.

The skeleton is made of titanium alloy, and the ceiling is made of bulletproof crystal glass, which is light-transmitting and cold-proof.

Looking down from the sky, Su Yuan's survival base was covered by black glass, and it was impossible to see the situation inside clearly.

The automatic dome is erected on the steel city wall around it, supported by nine huge titanium alloy columns in the middle, which is very firm.

The system can be bound to automatically adjust the air, humidity, and temperature in the survival base.

The temperature difference with the outside temperature can be maintained at about 20 degrees.

That is, outside the survival base, if the temperature is minus 60 degrees, the temperature inside the survival base can be kept at minus 40 degrees after being adjusted by the automatic dome.

In this way, Su Yuan only had more than 2500 million survival points left in his hand, and he suddenly felt a little poor.

With the automatic dome, the wind generator is no longer suitable for installation in the survival base.

Su Yuan simply moved the two wind generators to the steel city wall.

A row of wind power generators can be installed on the three-meter-thick steel city wall.

After all this was done, it was almost dark.

Su Yuan didn't try to upgrade the land again, and the survival points in his hand were saved to buy seeds tomorrow.
