Global Catastrophe: Open with 1000 Acres of Survival Base

Su Yuan raised his hand and shot the drone equipped with a high-definition camera with a laser gun four or five times.

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

Immediately, two other drones shot at Su Yuan.

The two drones were modified and equipped with small automatic machine guns that can fire 100 bullets.

The bullet hit the protective mechanical exoskeleton on Su Yuan's body, causing sparks to fly.

Although it could not hurt Su Yuan, the huge force shocked Su Yuan back again and again.

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

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

Su Yuan's protective mechanical exoskeleton also suffered some damage and needs repair.

After picking up the wreckage of three drones, Su Yuan found that one of them was still intact, while the other two had been scrapped.

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

This was a good idea. Su Yuan held the drone that was still intact and put it into the automatic maintenance machine room.

Then he closed the door to the maintenance room and saw a series of robotic arms repairing and transforming the drone in an orderly manner.

Repairing and modifying the drone does not require survival points, but only consumes some electricity.

What kind of transformation he wanted to make, all he needed to do was tell Su Yuan his idea to Xiaoyu, and Xiaoyu would be able to 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 captured a drone. Do you want to recycle it or upgrade it?

Su Yuan didn't want to recycle it, but he wanted to know the price of recycling it.

"Xiaoyu, how many survival points can you get by recycling this drone?"

"Master, 30,000 survival points!"

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

Ding, upgrading to a multi-function drone requires 300,000 survival points. Do you want to upgrade?

"upgrade!"

Ding, the upgrade was successful.

[Multi-functional unmanned reconnaissance aircraft can cruise 100 kilometers when fully charged, with a maximum flight altitude of 1,000 meters and a maximum reconnaissance range of 10 square kilometers. 】

[Upgrade to autonomous drone level 1, get 5 million survival points, and be able to conduct autonomous reconnaissance! 】

"Continue to upgrade!"

[Level 1 automatic drone can cruise 200 kilometers when fully charged, with a maximum flight altitude of 1,100 meters and a maximum reconnaissance range of 15 square kilometers. 】

[Upgrade to autonomous drone level 2, 10 million survival points, and can receive detection radar signals! 】

Detect radar signals? It may be possible to monitor the radar signals of surrounding private bases.

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

"Xiaoyu, from now on, when you start planting food during the day, you can use an automatic drone to monitor the surrounding situation. If there are any strange beasts or other production bases invading, please notify me at any time!"

"Master, don't worry, as long as there are any abnormalities, I will report to the master at any time!"

Then Su Yuan, with the attitude of giving it a try, carried the remains of the other two drones into the maintenance room and asked the maintenance machines to disassemble and assemble them to see if they could assemble a useful drone.

A moment later, Xiaoyu received a message from the automatic maintenance machine room.

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

"Can a laser gun work?" Su Yuan said.

"Yes, laser guns can completely deal with ordinary alien beasts or ordinary drones!"

Su Yuan then spent another 10 million survival points to buy a laser gun, assemble it on a drone, and upgrade the attack drone to automatic drone level 2.

[Automatic drone level 2 - attack type: fully charged, it can cruise 200 kilometers, have a maximum flight altitude of 1,100 meters, a maximum attack range of 500 meters, and can attack 300 times. 】

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

On the other hand, Instant Noodles has also harvested all mature soybeans. Although the production has been reduced a lot, Su Yuan still earned more than 60 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 210 million survival points in his hand.

It will still be dark for a while, but the temperature is already dropping rapidly.

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

I thought silently about the steel fence.

Ding, the steel fence is damaged. Repair requires 30,000 survival points. Do you want to repair it?

"repair!"

Ding, if the repair is successful, you can upgrade it to level 2 steel fence. It requires 500,000 survival points. Do you want to upgrade?

"upgrade!"

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

"Continue to upgrade!"

Su Yuan spent more than 35 million to upgrade the steel fence from level 1 to a steel city wall.

[Steel City Wall Level 1: 10 meters high, 3 meters thick, 3 meters deep underground, and 7 meters exposed above the ground. It can withstand the impact of ordinary level 9 alien beasts! 】

[Upgrade to Steel City Wall Level 2, 20 million survival points, 12 meters high, 4 meters thick, 3 meters deep underground, containing 10% titanium alloy, can withstand invasion level: Level 1 alien beast impact! 】

Invasion level?

Because the most powerful strange beast Su Yuan has seen so far is the Ma Ying.

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

Therefore, Su Yuan feels that the current level 1 steel city wall is enough, and there is no need to upgrade it to level 2 for the time being.

The most important thing is that three drones suddenly appeared today, awakening Su Yuan.

He felt the need to install a dome so that drones wouldn't be able to fly overhead and spot what was going on in his survival base.

A dome needs to be installed, and it has to cover a thousand acres. An ordinary dome will definitely not be strong.

Su Yuan gritted his teeth and spent 150 million survival points to buy a titanium alloy automatic dome.

The frame is made of titanium alloy, and the ceiling is made of bulletproof crystal glass, which transmits light and prevents cold.

Looking down from the sky, Su Yuan's survival base was covered with black glass, making it impossible to see what was going on inside.

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

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

The temperature difference between it and the outside temperature can be maintained at about 20 degrees.

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

In this way, Su Yuan only had more than 25 million survival points left in his hand, and he suddenly felt a little poor.

With automatic domes, wind turbines no longer fit inside a survival base.

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

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

After doing all this, it was almost dark.

Su Yuan didn't try to upgrade the land anymore. He still had the survival points in his hand to buy seeds tomorrow.
