Global Voyage: My Probability 100%

28 hours later, the second stage of the frozen world, the afternoon of the 16th day, the temperature dropped by 220 degrees in total, and the outdoor temperature was minus 200 degrees.

The temperature dropped by 20 degrees again, the thickness of the ice layer on the sea surface reached 20 meters, and the air became thinner.

During the period, Sophie Bin and Ma Xiaoting felt that although they could continue to break the ice to make the aircraft carrier move.

However, the manpower and material resources spent on ice breaking are too high, and too much time is wasted on ice breaking every day.

Therefore, after discussing with Chen Feng, they directly returned the two aircraft carriers to the base port and stopped sailing. The next task of patrolling and hunting mutant sea beasts was carried out directly on foot.

Anyway, the ice is very thick, and you can walk.

Sophie Bing, with multiple binoculars, and his two black subordinates, more than a dozen Level 2 intensifiers, patrolled the base on foot.

Ma Xiaoting relied on the unmanned reconnaissance level in the sky to first search for the location of the mutant sea beasts in the sea, and then went out to hunt and kill. She only set out with a few female soldiers. Although the number was small, the combat effectiveness was not bad at all.

It's just that the ice layer is very thick, the detection ability of the unmanned reconnaissance aircraft is weakened, and it is more troublesome to break the ice to kill the sea beasts under the sea. In addition, the number of mutant sea beasts hunted and killed in the past two days has dropped significantly.

Moreover, it is difficult to find high-level mutant sea beasts. All encounters are low-level sea beasts, but they can barely get some gains.

Chen Feng was staying in his room at this time, because the three murlocs of Meimei were being upgraded, and there was no one on the vehicle for the time being. Everyone was using tinder spar to maintain the temperature, so Chen Feng leaned against them to prevent them from freezing. die.

At this time, Chen Feng suddenly received a report from the female soldiers.

"Captain! We have been mining continuously for more than a day. Although everyone is not very tired, the consumption of tinder spar is too great. At present, everyone's tinder spar only has the last bit left. In another hour, all the tinder spar. When it is exhausted, the level 1 and 2 enhancers we mine will not be able to continue mining!"

Looking at the female soldier's report, Chen Feng nodded. Although Ma Xiaoting has been hunting sea beasts, she has only got hundreds of them in a day, which cannot be used by 2,000 people in large quantities at the same time.

The mining and other meetings under the sea can only be suspended first, or return to the base, so that the light of firefly BUFF can play a role. At that time, although iron ore cannot be mined on a large scale for the time being, but submarines enjoy the BUFF, still Rare metals can be mined.

"Go ahead and ask everyone who digs iron ore under the sea to return to the vehicle, and then count the number of iron blocks excavated!"

After more than a day of digging, Chen Feng was also curious about how many iron blocks the nearly 2,000 people had dug up.

Under Chen Feng's orders, nearly 2,000 people returned to the base one after another and were counting the number of iron pieces.

When Chen Feng saw that the personnel on the vehicle came back and the BUFF effect of the firefly light appeared, he suspended the use of the tinder spar.

However, Chen Feng suddenly felt that the vehicle at the moment was still a little cold. The temperature was 200 degrees, and the buff offset the cooling by 190 degrees. The temperature in Chen Feng's base at the moment was only minus 10 degrees.

That's it for now, look back and see if you can recruit more people to relieve the low temperature.

After a while, a female soldier brought the sorted iron blocks to Chen Feng.

When Chen Feng knew the specific number of iron blocks, his face was also very pleasant.

In one day, the number of iron blocks excavated by nearly 2,000 subordinates reached 300,000 units.

The follow-up base is upgraded to level 50, which requires about 270,000 iron blocks, which is completely enough.

In addition to the iron blocks, the female soldiers handed in together, and everyone's survival points, because it was the second day, the survival points had been refreshed, and they needed to be collected and handed over to Chen Feng.

A total of 1.1 million survival points.

Turtle! Directly back to the book in one day.

Chen Feng spent 1.2 million survival points yesterday, and today the survival points are back again. It was a correct decision to let his subordinates go to the sea to mine. Unfortunately, there are not enough spark spar, otherwise, if you continue to dig, you will have more wealth.

In addition to most of the iron ore excavated by their subordinates, Zhou Lingrui and Wang Ruoxi also drove a submarine to excavate a large number of copper and silver blocks in the ore caves. The base is level 50.

Put away the distracting thoughts, since there are enough materials now, Chen Feng is going to upgrade the base directly to level 50 and open the level 6 mall! Get system rewards for level 50 vehicles.

After collecting the required materials into the warehouse, Chen Feng walked into the fortress control room.

Open the properties bar and get ready to start the upgrade.

"upgrade!"

After Chen Feng clicked the upgrade option, the system prompt sounded.

[The material deduction is successful, your sea base vehicle is being upgraded to level 48, and the required time is 28,000 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 28,000 hours can be completely reduced. 】

[The sea base has been upgraded to level 48 successfully! 】

Sufficient material, then go up!

[The sea base has been upgraded to level 49 successfully! 】

[The sea base has been upgraded to level 50 successfully! 】

[The level of the sea base has reached the highest level, please purchase the corresponding vehicle upgrade drawings from the mall to open the subsequent types of vehicles in the sea base. 】

[Congratulations to player Chen Feng, the sea base has reached level 50, and the level 6 mall has been opened. Please check the goods in the level 6 mall by yourself! 】

[Player Chen Feng, your sea base vehicle is the first to upgrade to level 50. The following system will issue an integer level reward to your warehouse, please check it yourself! 】

Level 50!

The sea base has finally reached level 50. Although it will be a new beginning, after upgrading to level 50, Chen Feng has gained too many benefits.

The first is the change of the base itself, and the area has increased again.

The outer ring width becomes 1000 meters, and the buildable options also change.

【House 0/500】

【Port 3/5】

In addition to the changes in the vehicle, the Level 6 mall has also been opened again, which will also update new products, the most important being the [Level 5 Enhancement Potion] and more advanced vehicle upgrade drawings. UU Reading www.uukanshu.com

Taking the potion can be upgraded to a level 5 enhancer, purchase and use the vehicle upgrade blueprint, and the next large level of vehicle types can be opened.

Chen Feng wanted to check the mall for the first time, but he heard the system prompt that the first integer-level reward for upgrading the vehicle to level 50 was also distributed to the warehouse.

At this time, Chen Feng was so excited that he didn't know what to do.

In the end, Chen Feng couldn't hold back his curiosity and wanted to know what color quality would be of a prop with a higher quality than gold.

So, Chen Feng first opened the warehouse and observed the rewards of the system.

With a quick glance, Chen Feng saw the reward item at a glance, because its special color makes it hard to miss it.

Observe the quality.

Dark gold! ! !
