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

Su Yuan turned off the computer and checked the earnings during the day.

During the day, 180 million kilograms of grain was harvested, all of which were put on the shelves by Xiaoyu, plus the remaining 34 kilograms of grain before, by this time, all of them had been snapped up.

There were 104 million exchanges, and 2330 million kilograms of materials were exchanged.

Stores were exchanged 75 times, and 7.5 million survival points were rewarded.

After Su Yuan recycled all the materials, plus the survival points earned in the city ruins during the day, he had 628.3 billion survival points in his hand.

Afterwards, Su Yuan directly spent 600 billion survival points to purchase an ordinary large-scale ion thruster in the system mall.

Ding, it is checked that ordinary large-scale ion thrusters and nuclear power generators meet the upgrade conditions of the survival base. Do you want to upgrade?

"upgrade!"

Ding, the system is being upgraded, resources are being integrated, and the current progress is 10%.

Su Yuan waited patiently, this upgrade seems to take a long time.

The sound of booming and booming sounded in my ears, and the entire survival base seemed to be undergoing drastic changes.

Ding, the upgrade is successful!

Su Yuan clicked on the base to view various data.

【Level 2 Survival Base】

【Host: Su Yuan】

【Name: Dragon City】

[Area: 1200 mu of land]

[Power: Ordinary Large Ion Thruster]

[Speed: Mach 1]

【Flying altitude 15000 meters】

[Equipment: one intelligent survival cabin, one piece of speed land, one piece of endurance land, one survival butler, two intelligent farming robots...]

Su Yuan was stunned. From the data, it seems that only the multi-functional living room has become a smart living cabin, and nothing else has changed.

"Xiaoyu, help me display the stereoscopic projection map of the survival base!"

"Okay, master!"

Xiaoyu moved forward slightly with her fingers, and a three-dimensional projection map of a survival base appeared in front of Su Yuan.

On the whole, Su Yuan's survival base is like a giant flying saucer.

Covering an area of ​​1200 acres, the titanium alloy fortress has become a fully automatic titanium alloy armor, extending up to 40 meters and down to 60 meters.

Then, petal-like titanium alloy plates can be extended outward from the top and bottom, forming an absolutely closed flower bone.

In this way, the top and bottom of the survival base are protected by fully automatic titanium alloy armor.

The height from the center of the upper flower bud to the center of the lower flower bud is 130 meters.

The titanium alloy plate extends 15 meters outward, adding up to 30 meters.

Inside the survival base, it is divided into three layers.

The 9 meters below the ground are filled with dirt, and the 10 meters are covered with a layer of 1-meter-thick vibrating steel plates. This layer of steel plates is as big as the entire survival base, supporting all the equipment in the entire survival base.

Further down is the power layer, which is equipped with ordinary large-scale ion thrusters and assembled nuclear power plants.

Ordinary large ion thrusters are installed in the center of the entire survival base.

And there are 10 keels with a thickness of 15 meters and a width of 20 meters, which are connected with ordinary large-scale ion thrusters, 8 of which are on the horizontal plane, integrated with a 1-meter-thick vibrating steel layer.

The other two are on the vertical plane, extending to the center of the flower bone formed after the automatic titanium alloy armor is closed.

All keels are made of vibration gold to ensure the stability of the survival base when moving.

Next to the installed ordinary large-scale ion thrusters, the system is also equipped with a fully automatic cab in a humane manner.

Su Yuan can give instructions through the system, or enter the fully automatic cab and drive manually.

Behind the ordinary large ion thruster is a nuclear power station assembled by melon seeds.

Including power generation core temperature control equipment, air environment control equipment, safety assurance control equipment, etc., and automatic power generation control system room.

In the automatic power generation control system room, manual operation can also be switched.

The power layer is from the 11th to the 40th meter, but the large ion thrusters and the assembled nuclear power plant occupy an area of ​​less than 500 mu.

In the remaining space, Su Yuan can install other equipment in the future.

To 41 meters, there is another layer of 1-meter-thick vibrating steel plate, which is connected with the survival base as a whole through the keel on the vertical surface.

There is nothing from 42 meters to 60 meters. In the future, Su Yuan can hang various weapons on the vibrating steel plate layer.

And upwards from the ground, 25 meters is the automatic dome, and there is nothing above the automatic dome.

The space that Su Yuan can use is the space above the ground, the power layer, and the space below the power layer.

Later, Su Yuan also discovered that there was a super-large elevator that ran through the entire production base.

You can take the elevator, go down from the ground to the power layer, and pass through the power layer, and then through the bottom vibrating steel plate, you can leave the survival base from below.

Moreover, large elevators can carry not only people but also goods, and even automatic handling robots can take them.

The smart survival cabin he lives in is just next to the large elevator, like an airship, embedded in the middle of the ground and the power layer, with the ground floor exposed at the top.

Inside the intelligent survival cabin, there are 9 floors in total.

If the survival base suffers a devastating blow, the intelligent survival cabin can break away from the survival base and escape alone.

However, the intelligent survival cabin is currently an empty shell, belonging to the zero-level state.

Su Yuan clicked on the Smart Survival Cabin to check its properties.

[Smart Survival Cabin: Level 0]

[Area: 9000 square meters]

[Wall thickness: 3 meters vibrating gold steel plate]

[Automatic vibrating golden door: 3 tons]

【Power: None】

Su Yuan found that each floor was 1000 square meters, and the layout was the same as what he had arranged before. The 5th to 8th floors underground were all empty.

Su Yuan still lives on the 4th floor underground, but the area is bigger and there are many more rooms.

"I'm going, this upgrade is so fierce!"

Ding, congratulations to the host for successfully upgrading the survival base to level 2. You will get a chance to upgrade any two devices to two levels in a row. You will also be rewarded with a smart giant laser cannon and a smart giant freezing cannon, both of which have been distributed to the host's backpack .

Su Yuan jumped up happily, and when he opened the backpack, he saw a giant laser cannon and a giant freezing cannon.

[Intelligent Giant Laser Cannon: Level 1, after gathering energy, it can fire once every 15 minutes. It can emit a laser beam with a high temperature of more than 3 degrees, which can kill lord-level beasts. 】

[Intelligent Giant Extreme Freezing Cannon: Level 1. After gathering energy, it can fire once every 15 minutes. It can emit ultra-low temperature cold currents exceeding minus 255 degrees, and can kill lord-level beasts. 】

Su Yuan discovered that the barrel of the intelligent giant laser cannon was five times thicker than the laser cannon equipped by Niu Dali. One shot was equivalent to Niu Dali firing five consecutive cannons.

The disadvantage is that the cooling time has reached 15 minutes. If you can't die with one shot, you can only turn around and run away.

Su Yuan installed two cannons under the power layer and hung them on a one-meter-thick vibrating steel plate. When an attack needs to be launched, he only needs to put away the fully automatic titanium alloy armor under the survival base to expose the two cannons The gun barrel will do.

The turrets of the two cannons can be rotated 360 degrees to attack the enemy without dead ends.

Then Su Yuan used the free upgrade opportunity to upgrade the ordinary large-scale ion thruster by two consecutive levels and upgrade it to a fully automatic large-scale ion thruster, so that the speed of the survival base can reach Mach 2.

Then upgrade the ordinary nuclear power generator to two levels in a row, and upgrade it to an automatic nuclear power generator, which can generate 200 million degrees per hour.
