Global Voyage: My Probability 100%

Now Chen Feng's two vehicles are level 45.

According to Chen Feng's plan, he wants to give priority to upgrading the marine base vehicle, upgrade it to level 50, and enlarge the base's 'area', 'defense' and other characteristics.

Now the global natural disaster is frozen, the temperature is getting lower and lower, and the ice layer on the sea surface has become thicker and thicker.

Just now, Chen Feng also learned that the ice layer has increased from ten meters to eleven meters. If this continues, when the extreme temperature of 273 degrees absolute zero will be temporary, the ice layer on the entire sea surface may reach 100 meters or even kilometers. Or completely frozen.

At that time, even if it is how to break the ice, there is no seawater, and the lightweight vehicle such as the aircraft carrier cannot travel, and everything can only rely on the sea base.

This is why Chen Feng has been anxious to upgrade the base.

Even if he doesn't get the system's integer-level rewards as soon as possible, if Chen Feng gives priority to upgrading the aircraft carrier, maybe he is already level 50 or higher, how can he be surpassed by people like Amirshui.

Since he prioritized upgrading the base, Chen Feng simply budgeted how many materials would be needed to upgrade the base to level 50.

After all, system rewards that are one level higher than golden quality are still very attractive, and it is the best to get them.

The current base is level 45.

Upgrade material requirements:

Timber (230,000 remaining, 50,000 needed)

Plant fiber (220,000 remaining, 50,000 needed)

Iron (130,000 remaining, 60,000 needed)

Copper Block (100,000 remaining, 40,000 needed)

Silver Nuggets (60,000 remaining, 20,000 needed)

Gold Nugget (20,000 remaining, 3000 needed)

Platinum (180 remaining, 50 needed)

Battleship or Fortress Heart (10 remaining, need 5), Cruise Ship Heart (20 remaining, need 3) or Sailing Heart (700 remaining, need 30) or Raft Heart (1000 remaining, need 1000)

Number of residents reaching the target: 1000 required, currently 1740

After reading the materials required for the base upgrade,

Chen Feng frowned. Every time he upgraded successfully, the material of the next level would be improved, and the amount of improvement was about 1/10 of the previous one.

At present, the materials on Chen Feng's body, if you upgrade the base, there is no problem with two or three levels, but if you want to upgrade to level 50 in one go, it is definitely not enough.

Except for some rare gold nuggets and platinum Chen Feng, because there are many treasure chests, there are a lot of materials after decomposition. These materials are still abundant, but all other metal materials are scarce.

It is easy to say that wood and plant fibers can be purchased directly with Survival Points in [Trade].

Because such materials are only needed for vehicles in the direction of the fortress' development, such vehicles are relatively rare, so these materials are not valuable on the market and can be easily purchased.

However, metal materials are not only expensive to purchase, but also have a price and no market, and it is difficult to buy them. Even if Chen Feng keeps buying, I don't know if I can receive 1,000 units in one day.

A rough calculation shows that iron, copper, and silver blocks are all in short supply, and each will cost about 400,000, 300,000, and 150,000.

It is definitely impossible to rise to level 50 in one go. At present, Chen Feng's more than 600 subordinates are all mining under the sea.

Zhou Lingrui and the others used submarines to dig rare metals. In one day, there were about 50,000 and 20,000 copper and silver nuggets.

In other words, if you want to rely on your subordinates to mine and collect materials to upgrade, it will take at least three days.

This time is a bit long, Chen Feng knows that although Amirshui has been warned before, and he also knows that he has no hourglass props for the time being, but if the cargo is good and he is not afraid of death, Chen Feng will have to worry about it.

Therefore, even if it only takes three days, Chen Feng does not want to wait.

Chen Feng sat on the sofa in the control room, rubbing his chin, slowly thinking about how to quickly obtain materials.

After thinking about it for a long time, Chen Feng felt that there was only one way to do it right now.

There are more than 1,000 old, weak, sick and disabled people brought by Sophie Bin in the base last time. Although they signed the resident contract scroll, they have been placed by Chen Feng in the cabin of the base to eat and wait to die.

Now if they want to increase the mining speed, don’t they happen to be ready-made!

If more than 600 mining people become nearly 2,000 people, then the mining efficiency will be increased by about three times. As a result, it will take three days to upgrade the base to level 50, and only one day will be enough!

It’s just that they are all old, weak, sick and disabled. If they want to have a certain ability to work, they must take [the old, weak, sick and disabled repairing medicine]. There are more than 1,000 people, and each person has a bottle of medicine with 1,000 survival points. That's one million survival points.

Chen Feng now has 1.03 million survival points on his body. After helping the old, weak, sick and disabled to become normal people, there are only 30,000 left. He has to upgrade them to level 1 enhancers, which is more than 100,000 survival points. It's not difficult to have a poor survival point, and you can get it together from Ma Xiaoting and the others.

Chen Feng smacked his lips, more than 1 million survival points, the number is really scary, if it wasn't for the fact that he had been mining a lot these days, he wouldn't be able to get 500,000.

Since he wants to use it, Chen Feng doesn't feel bad. Anyway, his subordinates have excavated a lot of metal materials today, and they can refresh their survival points tomorrow. It is estimated that they can return at least one million points.

Turning more than a thousand old, weak, sick and disabled into labor is the real wealth.

Just do what he says, Chen Feng plans to upgrade the sea base vehicle with the materials at hand until the materials are exhausted, and then go to the old, weak, sick and disabled.

Open the attribute bar of the base, and Chen Feng directly chooses to upgrade.

[The material deduction is successful, your sea base vehicle is being upgraded to level 46, and the required time is 24,000 hours! 】

[Acceleration BUFF: There are currently 1,950 creatures, and each person can reduce the upgrade time by 100 hours, and the upgrade time of 24,000 hours can be completely reduced. 】

[The sea base has been upgraded to level 46 successfully! 】

There are nearly 2,000 intelligent creatures in the base. After the acceleration buff is triggered, the more than 20,000 hours of upgrade time disappears.

This makes Chen Feng very happy. He is willing to upgrade the base. The main thing is that the vehicle in the development direction of the base has an acceleration buff compared to the vehicle such as the aircraft carrier. As long as there are enough intelligent creatures on the base, even if it is not a resident who signed a contract with Chen Feng , it can also reduce the upgrade time, make the upgrade time disappear completely, and an hourglass does not need to be used.

The base was upgraded to level 46. Chen Feng glanced at the materials. Except for the heart of the raft, the other materials were enough to upgrade again.

For small-level upgrades, all kinds of vehicle hearts can be used, but the lower-level vehicle hearts need more quantity.

The heart of the raft that Chen Feng and Chen Feng captured and acquired by the newly arrived old, weak, sick and disabled on the vehicle finally ran out.

Next, Chen Feng chose the heart of sailing and began to upgrade.

The heart of the low-level vehicle, Chen Feng, has a lot in his hands, so he doesn't panic at all.

[The material deduction is successful, your sea base vehicle is being upgraded to level 47, and the required time is 26,000 hours! 】

[Acceleration BUFF: There are currently 1950 creatures, and each person can reduce the upgrade time by 100 hours, and the upgrade time of 26,000 hours can be completely reduced. 】

[The sea base has been upgraded to level 47 successfully! 】

The two upgrades were successful, and the metal materials were almost consumed, and the upgrade could not be continued.

The current base, because it has been upgraded two levels in a row, has changed its attributes again.

One is the width of the outer land, and the other is the [houses] and [ports] that can be built.

The width of the metal ground on the outer ring increased again by 200 meters, reaching 700 meters, including the 500-meter-diameter fort in the center of the base.

The diameter of the entire base has reached 1900 meters, and it is truly a steel island.

Buildable house port changes:

【House 0/400】

【Port 3/4】

Chen Feng does not plan to build the additional constructable facilities for the time being. One is that they are temporarily unavailable, and the other is that there are not enough manpower.

Take advantage of the time when the sea is not completely frozen, you must quickly dig in the seabed.

Temporarily upgrading the base to level 47, Chen Feng got up and went to the lower building in the base fortress, ready to give those old, weak, sick and disabled a gorgeous transformation.
