The construction of the Arctic base is much simpler than that of the Daisetsuzan base.

Shiro changed the shape of the ice according to Naruto's instructions, creating a large ball and a small ball, a three-layered spherical ice cap.

The innermost ice sheet covers an area of 10 kilometres, with the outer ring looping every kilometre.

This structure is like the double glazing of a thermos flask, which effectively insulates the temperature inside and outside the ice cap.

It plays the role of thermal insulation and cold insulation.

In fact, Naruto originally planned to build something more grandiose, but the conversion of chakra into ice attribute provided by the spiritual network is much less efficient than using his own chakra, and now this project is already the limit of what Shiro can accomplish.

But it doesn't matter, when Naruto's body has time, it can be expanded again.

The convex lens structure of the ice cap has a strong effect of concentrating light, and the night is fine, but if the sun comes out, I am afraid that it will be grilled directly.

Naruto asked Gollum to control the deformation of the steel with a steel escape, adding a layer of steel film to the middle layer.

It's not all sealed, the top layer is sealed, the middle is honeycomb, and one circle is sealed and one circle is transparent.

Where there is too much light transmission, add a light-blocking steel film in the inner or outer layer.

Generally, when the sunlight is sufficient, the light needs of the interior can be met by diffuse reflection.

Once the insulation has been built, the next step is the inner living area.

Little Golney is on the field again, and the all-metal room is quickly formed under the smashing of chakra and steel teleported from the Snow Country, regardless of the cost.

The structure of the living quarters was designed by Naruto, with a total of thirty-six rooms, arranged one next to the other in a ring.

The exits of the rooms are all inward, connecting to the circular common area in the middle.

The common area has a living room, a temporary laboratory, a kitchen, and other common facilities.

And the main laboratory, digging down, is now open to four floors.

On the ground floor, there is a laboratory area for mechanical aspects such as armed armor.

B2 floor, biological laboratory.

The negative three floors are the storage room for the regeneration of biomass.

The fourth floor is the core computer room of the spiritual network.

With the convenience of ninjutsu, the entire project was completed within six hours.

"I can't do it anymore...... Let me die for a while......" Little Gunni wrapped the last room in a film, and poured the whole person directly into Big Guni's arms.

At the same time, Bai's body, which could only support a month, only had the best breath left.

"I feel like I'm weak now, and this body is about to lose its support......"

The white body has begun to fall off the slag, pieces of ash, like dandruff, and a few pieces will float down from time to time.

Naruto comforted, "You all have a lot of credit, and each person is rewarded with a thousand points." ”

Xiao Guni rolled her eyes, she was the person who was the least lacking in points, and hurriedly protested: "I don't want this reward, I want something delicious, I want to eat the pastries made by Sister Xia." ”

Summer-made pastries?

Not to mention that Gunny wants to eat, Naruto also wants to eat it.

Happily promised: "When the arrangement here is finished, I will summon your sister Xia to play for a few days." ”

Bai is easier to talk and doesn't ask for it.

However, Naruto also added a reward to her: "The Arctic base is very important in the long run, this time you will complete an S-class mission." ”

Bai was stunned.

She wants task scoring more than a thousand points.

Because there is a requirement for this for the ID card upgrade.

And an S-level task is scored...... It means that she is one step closer to being promoted to three stars.

Promoted to three stars, she can be resurrected and never kill adults again.

Bai's heart was a little excited.

The ash spots on his body peeled off much faster.

But she didn't care, bowed and said, "Thank you very much." ”

Naruto's coal boss looked sufficient, nodded with satisfaction, and came back, "This is what you deserve." ”

Naruto will inform Big Fat of the reward given to Shiro.

Da Fei rewarded Bai with five-star permissions.

The system prompt sounded in Bai's ears: "Complete the S-level task of building the Arctic base, reward 1,000 points, and S-level evaluation one." ”

"According to the accumulation of scores, you can split an S-level assessment into three A(ji) assessments, and use one A(ji) assessment to split into 50 B-level scores to promote two-star identity cards, do you want to split the promotion?"

White chose to be promoted.

Then the S-class rated medallion in front of Shiro's eyes shattered into three pieces, and in an instant, it turned into three A(ji) medals.

Then one of the A(ji) medals shattered again.

At this time, a system prompt came to my ear: "You have a 10-party upgrade package waiting to be downloaded, do you want to download it?" ”

Tip: "This download is free. ”

White chose yes.

The system prompts: "The download is complete, the upgrade package starts to be installed, please ensure that the chakra is sufficient during the installation process." ”

Then the card carried by Bai suddenly became hot, and the runes on it seemed to come to life, changing their form in the twist, becoming more and more complicated.

He was no stranger to the scene in front of him, and a few hours ago, when he installed the summoning function, he also saw this scene in front of him.

After three seconds, the runes on the card are finalized.

The control panel in front of the white eyes changed.

This is followed by a tutorial for the novice of the two-star identity card.

The two-star card has two more panels than the one-star card, chat and world map.

However, for Shiro, it was just one more world map, after all, the chat permission was opened shortly after Shiro went to the North Pole.

The world map unfolds, and the most detailed is the snow country.

Then Shiro saw a straight line he had taken leading to the North Pole.

While Shiro was familiarizing himself with the new identity card, Naruto received a message from Yakushidou.

"Boss...... What about you? ”

In the Daxue Mountain Laboratory, the pharmacist went all the way from the first floor to the top floor.

Fortunately, he used the earth to go up directly, otherwise this trip would be enough to exhaust him for half his life.

The result of the search is that there is no one.

Naruto was stunned for a moment and replied, "Ah, we just moved and built a base in the North Pole. ”

"The North Pole? Where is it? ”

Yakushidou apparently hadn't watched the video updates in the entertainment area yet, nor had he called up the world map.

The pharmacist replied with a sad face: "Then why don't you tell me?" I've just been at the base and looked for a big turn......"

Naruto wondered, "You're looking for Gunny?" Then you can talk to them. ”

Yao Shidou's face darkened, and he replied full of resentment: "That girl of Little Guni lied to me...... Say you're on the top floor......"

Naruto blinked, and couldn't hold back a "poof" laugh.

"This girl, ......"

"Then why don't you have a big goon?"

Yakushidou's face darkened......

He replied, "Big Gunny replied that she was with Little Gunny......"

Belch......

Big Goloni also lied? No way?

Wait, Big Gunny said to be with Little Gunny......

Naruto looked at Big Guni, who was indeed with Little Guni at this time.

Da Guni didn't sprinkle flowers, but the words he answered were misleading......

It can't be intentional, right?

Big Guni also learned badly?

Naruto asked Yakushi, "Why did you ask her?" ”

The medicine man's huddle squatted in the corner, "I asked, are you with Xiao Guni......

Naruto: "Poof......"

"Ahem, that ...... What do you ask them for? ”

The pharmacist replied, "Their clones need to be compared with the original cells, and I will ask them to extract the cells......

The pharmacist darkened: "But now I think it's okay not to compare...... Hum hum ......"
