Train Survival: You're really trying to survive!

The two huddled inside the snow house, while outside, a light drizzle fell.

Su Li chose a high-lying location, and with the addition of a layer of stones, he managed to prevent rainwater from leaking in.

The snow bricks used to build the snow house, filled with snow and air, are excellent insulation materials, allowing the temperature inside to rise continuously. Su Li didn't know the exact temperature, but it felt like around minus twenty degrees Celsius.

Su Li stroked Song Mingyu's hands in her arms, feeling the incredibly soft skin in some areas. These were originally frostbite, but Song Mingyu had healed the wounds with her own abilities.

Su Li said in a low voice, "These snow houses can only be used temporarily. If we want to survive here, we need to build proper shelters."

"Hmm...where should we build the shelter?"

"Actually, the best option is underground."

They had discovered this while they were underground: the elemental field surrounding the world was less active underground, which slowed down the accumulation of elemental erosion within their bodies.

Moreover, the surrounding temperature is much better underground than usual.

"But underground, we have to deal with the problem of oxygen."

Song Mingyu had a sudden inspiration: "How about using oxygen cylinders?"

"That won't work. Filling oxygen cylinders requires a basic workbench or specialized equipment."

For example, the oxygen generator that Zheng Hongyuan provided to them had a dedicated interface that connected to the system's oxygen cylinders.

Moreover, the two of them only brought four oxygen cylinders, and each oxygen cylinder is only enough for one person to use for about three hours.

Not to mention, Su Li and the others also needed to burn firewood.

“Let’s choose a cave,” Su Li said. “Let’s go look for a cave on this mountain tomorrow morning. If not, we’ll build a shelter outside.”

"Okay, it's all up to you."

Su Li nudged Song Mingyu's head with her chin and shook it. "Then I'm going to sleep first. Be careful to light the fire."

After explaining the precautions, Su Li lay down beside the fire and fell into a deep sleep.

A night in this world lasts for nearly 20 hours. Su Li and her companion don't need much sleep, and after taking turns on duty, they still have a long night to go.

With nothing else to do, Su Li and the other person chatted casually. As they talked, they unknowingly drifted into the topic of their respective cultivation practices.

The two shared their understanding of magical energy. Song Mingyu recounted to Su Li the moment of her sudden enlightenment and the vastness of nature she perceived, while Su Li shared with Song Mingyu her insights into the rotation of the sun and moon.

After a night of conversation, light gradually appeared outside.

"I've never actually seen a sunrise before in my life."

Su Li suddenly remembered this, so he climbed out of the narrow snow house door, put on his mask, and went outside.

Just then, the sun in this world was about to leap over the horizon. The sky was a hazy gray with a few thick clouds. The thin edges of the clouds slowly became clear, and then the sun, which gave a feeling of weakness, slowly climbed out of the horizon, revealing just a little bit of its edge.

Su Li gazed at the distant sun, which seemed unusually weak, and a strange feeling welled up inside him...

[If swordsmanship can be modified based on insights into the sun and moon, can magical energy cultivation also be modified in the same way?]

Su Li had some thoughts in his mind. The cultivation method he was currently practicing was the strongest foundational warrior cultivation method. Even his teacher said that, in terms of building a solid foundation, no other cultivation method was more suitable than this.

Unless someone modifies the cultivation method to better suit their own needs.

Su Li wrote down her thoughts, intending to think about them carefully later.

However, a thought suddenly struck Su Li.

He looked up at the distant clouds. "Since I came into this world, have I ever seen any clouds?"

Su Li searched his memory but couldn't find a definite answer. In his memory, the sky was always gray, and he had never seen any clouds. But did not seeing them mean that there were no clouds at all, or that clouds were too rare to see? He didn't have a definite answer.

Trust your instincts and prepare early.

Zuli returned to the igloo. The temperature was rising, and the liquefied carbon dioxide would re-vaporize, so it was not suitable to move around outside.

The two waited for about an hour. During this time, Su Li put out the fire, but she still felt very stuffy.

Fortunately, the terrain is high, so the stuffiness is bearable.

After getting dressed, Su Li and the other person went outside the snow house again.

After putting on their skis, Zuli and his companion began exploring the small hill. The hill was covered in snow, a vast expanse of white that sent chills down one's spine. The snow surface shone brightly under the sun, almost unnervingly so.

"Keep the snow house for now, as it will serve as our temporary shelter."

"it is good."

Su Li pressed down slightly with her feet, accelerating her movement towards the summit.

He planned to go to the top of the mountain to get a general idea of ​​its condition.

It took some time to reach the top of the mountain, and Su Li looked down.

They were located on the north side of the mountain, in a somewhat desolate area. On the south side of the mountain, there was a small grove of trees covered in snow.

"Over there!" Song Mingyu tugged at Su Li's clothes and pointed in a direction.

Su Li looked in the direction Song Mingyu pointed out. To the east of the mountain, there was a very chaotic snowfield. Su Li could see that the snow in this place had been repeatedly trampled.

"Are there monsters living here?" Su Li guessed.

"Shall we go take a look?" Song Mingyu asked.

“Let’s go take a look. There shouldn’t be any danger,” Su Li said confidently.

At this close range, if it were a powerful monster, it would have come over to say hello last night. If it didn't, it either wasn't strong enough, or it ran away.

The two pushed their ski poles and slid downhill, soon arriving at the messy snowfield.

Su Li tidied up, and Song Mingyu stopped first, took out her staff, and prepared to cast a spell.

Su Li pulled out the mountain slope and slowly approached. The situation was not good. He could run away directly with his skis. If he could win, he could smash the skis that were in the way and go up to talk to the person.

Upon approaching, Su Li examined the footprints, which were mostly those of canines. Beyond the footprints, she saw a small cave. The entire cave was clearly visible, about 6 meters deep, with a slightly upward slope inside, and no monsters inhabited it.

Su Li touched the wall of the cave. There were obvious traces of magic, as if some kind of magic was used to turn fossils into mud and then sculpted the wall by hand. There were also some hairs and footprints stuck to it, just like a concrete road that had been trampled by a dog.

Earth magic, canine footprints—Su Li suddenly thought of their good friends who provided them with meat, like wolves and deer.

"In any case, this is a good place. There are existing caves with some protective capabilities, which can be used to build shelters."
