My bedroom leads to the end of the world

Chapter 60 Air Pistons
Buzz buzz boom boom boom boom!
The excavator continued to advance, and the snowdrifts and ice blocks in front of it were stirred by the rotating cutter head on the snow wall outside the circle.

Behind the roadheader is a logistics transport sled carrying oil and fuel cells.

Not only is there something for the boring machine to eat, but there is also something for people to eat.

Julian stepped on the gas pedal with one foot, and hid his hands in front of his body under the quilt, shivering from the cold.

Nan Jing and Wen Te are also sitting in the cockpit, he and Julian are on the left and right, and Wen Te is in the middle who is warm.

The temperature in the snow cave was extremely low, and because it was too far away from the base, the newly dug snow cave lacked enough oxygen for everyone to breathe.

At the farther back of the boring machine are Celia, Verril and others sitting on the No. [-] sled.

It is not difficult to drag a few people in this snow environment, and Celia and others are unable to carry out intense exercise in this environment.

Breathing problems are worse than cold problems.

"Come here, go back first, I can't take it anymore..."

Nan Jing felt severe chest tightness, and a tunnel boring machine that could dig holes would not be enough unless the breathing problem was solved.

Julian's hands and feet were also cold from the cold, so he quickly turned the front of the car, began to dig forward slowly for half a circle, turned around and rushed into a snow track that he had just dug out and walked through.

After a successful U-turn, the roadheader reduced its rotation speed and began to return along a fixed route.

The snow tracks on both sides have been extended by half a meter. Fortunately, there are radar routes for guidance, and the range is not large.

It was faster to go back, and everyone quickly returned to the carport at Yexiao's base.

"go back!"

Nan Jing took the lead and quickly came to the mouth of the well, and everyone took turns ascending and descending to the underground shelter in sequence.

"Whoo~"

When I first entered the shelter, the warm air only caused a moment of discomfort, but soon my whole body happily accepted the warm atmosphere.

The frozen hands, feet and body finally recovered at this moment.

Nan Jing rubbed her hands together for a few seconds, and then took a big breath of fresh air in the room.

Back home from the freezer!

The rest of the people were also relieved after returning. Although there were no scary and dangerous enemies, the quiet and oppressive narrow space and the stuffy atmosphere made everyone very uncomfortable.

"Take a rest for half an hour and eat something."

Nanjing asked everyone to rest for a while, and after a pause, they began to discuss how to solve the air problem.

"There is no problem with the passage. As for fuel, as long as we can continue to move forward, we can get supplements from the base on the road."

"The problem is how to solve the air problem in the channel. Now we have to breathe even if we sit still on the boring machine."

"Algal Lyme cannot be entrained, Algal Lyme cannot survive outside temperatures, and relying on electrolyzed water is not practical."

Jill listened to Nan Jing's question, and said directly: "Use the zombie potion, you don't have to worry about breathing problems after you become zombies."

Nan Jing frowned and thought about this. It sounded like a solution, but if she had a choice, she didn't want to.

Celia and the others also had the same idea. Everyone naturally distrusted zombie potions, that is, zombie potions.

It would be interesting if it doesn't come back.

Jill has confidence in her own things, and other people still resist this product even after seeing Jill transforming from a zombie.

Is it interesting?Not funny at all!
Jessica suggested: "We can use algae lyme to produce oxygen. Although the zombie potion does not need to breathe, it will greatly reduce our combat effectiveness. In case of danger, the combat effectiveness and reaction of the captains will be reduced. and fail."

For weak chickens like Jill, zombie potions can increase resistance and strength, but for strong people like Celia, zombie potions are inferior things that reduce their physical fitness.

Jill's stuff was only for herself, not even for Alice, let alone for the rest.

"Can algae lyme survive the temperatures outside?" Winter said.

Nan Jing looked at Jessica, what Winter said, he said just now.

Jessica explained: "The algae Lyme cannot survive in the low temperature outside, but we can build a few underground insulation points on the road, as long as we set up one kilometer apart, we can solve the simple breathing problem."

"As for food, don't worry about it. It's enough to collect some corpses on the road. In this environment, the most indispensable thing outside is corpses, whether they are monsters or humans."

Wei Ruier said: "One per kilometer, is it enough?"

Nan Jing thought of something, and quickly said: "No problem, our boring machine is equivalent to a device with a piston, which is constantly pushing forward from behind, and the airflow in the passage can easily flow."

Jill saw that there was a solution, so he added: "Underground water can be used. I know the location of the nearby underground river. No matter how cold it is above, the underground river should not freeze to death. If we use it a little, we can build a resting place."

"We need to drill several wells to extract part of the geothermal heat. Considering that it is used for algae Lyme to decompose food, there is no need to go too deep if there is enough food."

After finding a way, Nanjing began to act.

The first is to determine the location of several underground rivers, and the second is to arrange the location of several rest points.

Not only does it give the algae Lyme oxygen to make, it's also where they rest when they run into trouble.

After all, that dilapidated tunnel boring machine doesn't look so reliable.

The algae lyme in the shelter have multiplied a lot after the food and temperature are sufficient, and some of them can be taken out for use outside.

"It's so lively." Susan walked in, and seeing everyone here, she looked at Nan Jing with a serious expression.

"Master, I have received requests for help from several bases. Now many bases outside need food and fuel. Ask each other if there is enough."

Susan's expression was indifferent. She had chosen to ignore the calls for help from outside several days ago.

"I think it's okay. The damned are almost dead now, and the rest of the people should understand the reality, so I asked a little bit about things."

Susan showed a kind smile, "I just asked them if there was anything valuable there, and the group of lowly bitches outside anxiously wagged their tails and contacted me."

When everyone was hungry and cold and felt unable to survive, Susan asked others on the communicator if there was anything valuable...

Nan Jing ignored Susan's bad taste and said directly: "Then is there anything valuable?"
