The two of them walked together, each pulling more than 100 kilograms of material on the sled, facing the dark ground covered with ice and snow along the way, with the help of lights, they could occasionally see some dead trees that were frozen, and due to the frequent appearance of sky launch vehicles, they could see the outline of some hills.

Everything here is as silent as everything is withering, there is not a trace of life, there is not a trace of movement, because there is no wind to patronize it, only the creaking sound of each person walking in the snow.

What makes them most uncomfortable is not the boring environment around them, but their inconvenient airtight clothing, a bit like a simplified version of a spacesuit, its main function is to protect against the cold, and it has also been modified in many places, such as the helmet's visual range has been expanded a lot, the clothes are softer and lighter, and the battery has been miniaturized, usually they don't need this, because they can pass through the core, a steady stream of electricity, the oxygen cylinder has not changed, but there are a few spare ones on their sled.

And the things they carry on their sleds, such as inflatable tents, a lot of food, and hot water mats, etc., generally speaking, they don't need these things, just in case, and as long as they go faster every time, they can easily get to the next open-air sub-base, as long as they go there, everything is fine.

Finding the sub-bases is actually very simple, whether it is to borrow a navigator to find it, or to find it directly through the naked eye, because these sub-bases have built high signal towers, and the signal towers have sun lamps on for a long time, and they can be seen from a distance.

Although there is no problem with safety, walking in such a cold world, the consumption of energy is still very large, clothes need to consume a lot of electricity, in order to have the effect of heat preservation, the main channel that can provide a large amount of electricity is only themselves, and the battery alone cannot be maintained.

This will inevitably seriously aggravate their physical exertion, so they will stop if they can't, then take out the heating container, put the frozen tolerable high-energy food in it, seal the lid, and then heat it up for about 10 minutes, and then they can drink.

Because the environment is too cold, so the drinking aspect has also been specially treated, without opening the helmet, by linking the straw, you can suck the food in the heating container, these foods are not the same as conventional food, are special high-energy food, basically no impurities, 99% can be converted into energy, after eating, there is no need to worry about the occurrence of internal urgency, after all, in such a harsh environment, it is too difficult to go to the toilet.

If you insist on going to the toilet, you can only set up an inflatable tent first, and then go inside before you can do it, just because the outside is really not suitable for this, and the body will freeze.

Such a high-intensity refining of the energy in the food and the conversion of energy to maintain a normal temperature, and also need to walk on foot and pull a sled, but it is a very difficult thing, of course, the benefits are also obvious, Zhenxun found that his strength can enter the rapid growth again, and the benefits obtained by Betty are even more obvious, she feels tired, it is the most painful one she has ever experienced in her life, fortunately, she still gritted her teeth and persevered, she knew that she had not reached the limit, and she clearly felt her own progress, She didn't want to let up if she didn't hurt her body.

After perceiving Betty's situation, Mahiro didn't step forward to help the other party, because it was not yet time to need her help, all she could do was to wait patiently for the other party to relieve herself, and then continue to act with her, she was talking all the way, and she didn't care if Betty listened or not, anyway, she was very energetic, and she squandered it at will, and in the face of such an energetic partner, Betty, who was tired of being a dog, was both envious and jealous, which strengthened her determination to become stronger.

After 12 hours of travel, they finally came to the foot of an open-air sub-base, and if they wanted to enter the sub-base, they still needed to walk another mountain road, they rested for a while below, and then sprinted to the top of the mountain in one breath.

Fortunately, the mountain is not high, not too steep, and there is a mountain road to go up, the top of the mountain seems to have been cut off, and a tall signal tower has been built there, in short, there is no other danger here except the difficulty of going uphill, so they went up to the top of the mountain smoothly, and entered the sub-base, where the person in charge has come out to meet them.

"Welcome to the 150766 subbase of the Corona Continent, my name is Harrison, and I am the person in charge here."

"Hello, my name is Zhenxun, her name is Betty, we are in the training, I hope to rest with you for a while, and then get some supplies."

"Well, I know all about you, and those things are ready for you."

"All ready?"

"Yes, you are not the first batch of practitioners to come here, of course you are prepared, besides, I am the first batch of practitioners, I was active with Rose, and I still had a lot of fun."

。。。。。

In this harsh environment, you can still have fun, Betty and Mahiro glanced at each other, and they both read a few pieces of information from each other's eyes, one is that these two people are the best of the Saint Crystal masters, and they are a team of husband and wife, as long as they meet these two conditions, they can easily deal with everything outside, and they can also play like playing in the mountains and rivers.

Soon after, Rose also came up from the depths of the ground, and after Harrison introduced each other again, they proposed to do activities together, such as eating, bathing, visiting Harrison's natural ecological space, and so on.

Harrison is so enthusiastic about entertaining them, there is also a reason, the first is that there are fewer people here, it seems very deserted, if there are guests visiting, most people will entertain them, everyone has a good time, the second is that they are optimistic about their future prospects, want to get to know them, expand their connections.

In this way, there was a lot of delay, and the recuperated Zhenxun and Betty began to set off again, while Harrison and the others waved their hands to see them leave, with the previous experience of hiking, this time they would walk more easily, which was also related to their adaptation to the environment and the growth of their strength.

Generally speaking, the terrain is relatively flat, and some of the more threatening places will be perceived by Zhenxun in advance, and then avoid these places, because they don't have to go carefully, which greatly increases their forward speed.
