Wang Xiaotie knew that his eye circles were definitely black. Pen & Fun & Pavilion www.biquge.info

Thankfully, I survived the long night.

"Lao Tzu has lived in this damn place for 2 days!" Facing the air, Wang Xiaotie vented loudly, covered the hole of the snow house with snow, and began the journey of further exploration.

This mountain range is relatively barren, the plants are not too lush, although the food is not as abundant as the previous one, but Wang Xiaotie still collected a lot.

The cold and low temperature weather is not without any benefits, at least you don't have to worry about the shelf life of the food, uh~ After all, Wang Xiaotie is now equivalent to living in the refrigerator, and it is still in the freezing area.

But it's been three days since I supplemented with protein, which is not a good sign.

The plants you eat contain only trace amounts of protein and fat, which is definitely not enough for survivors who consume a lot of physical strength every day.

Protein is the main raw material that makes up human organs, hormones and immune substances, so protein intake is a must. It stands to reason that normal people need to supplement about 80 grams of protein every day, while survivors like Wang Xiaotie or people who exercise a lot need more.

The other is fat, there are no legumes in this barren land, so protein and fat supplements are very lacking. To survive in cold places, fat is especially important.

Fat can supply heat, regulate body temperature and protect internal organs. Fats contain more carbon and hydrogen than carbohydrates. Therefore, more heat can be released during oxidation. One gram of fat releases 3 kilocalories, which is the highest caloric energy of any nutrient.

Secondly, it is also one of the important factors that make up the body's tissues and supply essential fatty acids.

In order to obtain these two necessary elements, Wang Xiaotie can only hunt animals and eat meat. But it's just too hard.

Animals and people alike, most of them don't like to stay in the cold. So there are few animals living in the subarctic and boreal regions. In addition, I don't have hunting tools like shotguns, so it is very difficult to hunt animals.

So while Wang Xiaotie was looking for the cave, he was also around the idea to see if there were any animals that accidentally froze to death. This is equivalent to buying a lottery ticket and trying to win the jackpot, only to get disappointment.

However, God did not completely give up on Wang Xiaotie in the end, and in his incredulous gaze, a pitch-black cave on the rock wall appeared in front of him.

Three steps and two steps, Wang Xiaotie immediately ran over to check.

This is not a regular circular cave, but an elongated triangle. It was as if it was like a crack between two cliffs, obscured from falling overhead. So the space inside is both large and narrow.

Big because of the height, Wang Xiaotie looked up at the top of the cave above, it was estimated to be more than 10 meters high, but between the two sides of the cave wall, the widest bottom was only less than a meter away. This is not an ideal place to live, but Wang Xiaotie does not intend to give up here, this is the only cave that he has found with great difficulty, and if he continues to look for it, he doesn't know if he can gain anything more.

During the day, he needed to renovate the place, otherwise the night would not be much warmer than outside.

A large number of branches were transported to the cave by Wang Xiaotie, and then a lot of sturdy wooden sticks were selected and stuck directly in the middle of the rock wall, so that it was easy to form a roof beam.

The collection of wood continued, and Wang Xiaotie was looking for wood that looked like it could burn, because he urgently needed to raise the fire.

The experience of two nights did not freeze him to death, it was really Lady Luck who opened her arrogant chest and hugged Wang Xiaotie tightly a few times. But no one can say for sure, whether that bitch is tired of Wang Xiaotie and whether he will ruthlessly abandon him tonight.

Better do it than wish it done. Overall, it's important to start a fire!

In the subarctic zone, the plants are relatively simple, unlike the tropical rainforests, where there are all kinds of unknown trees and plants.

Coniferous trees are the most abundant here, and hardy larches and spruces are important components of the jungle. The ground is covered with a thick layer of moss and lichen, which are the food of some omnivores or herbivores.

Humans can also eat moss to satisfy their hunger, but on the premise that food can still be found, Wang Xiaotie does not want to try that kind of thing. It looked disgusting and unappetizing. (Note: Very few mosses are edible, and seaweed can be cleaned and put directly in the mouth.) Moss on the stone needs to be treated. But most mosses are inedible, so don't really use them as a food source. ）

Wang Xiaotie wasn't looking for edible moss, he was looking for dried moss, which was the only thing here that could be used as a firestarter.

With a sharp mountain opening knife, the bow drill made by Wang Xiaotie looks much more beautiful. However, looking good does not mean that it is necessarily easy to use, and lighting a fire depends not only on physical strength, but also on luck.

Everything was ready, and Wang Xiaotie began a long journey to make a fire.

Use a knife to scrape a lot of wood chips from the dead branches, and then mix them in the dry moss. was then pressed by Wang Xiaotie under a relatively large piece of wood.

The fire bow is a simple life skill, (you can do the Niang search: the bow drill fire. But it takes a lot of time to practice. Fortunately, Wang Xiaotie has twice used this primitive way to make fire, and his confidence is still relatively sufficient.

To make a fire bow, you need a bow with a natural bend, and then tie a sturdy rope to both ends of the bow. The rope must not be too loose or too tight. (The rope can also be woven from some rattan in nature, strong bark.) As long as it's sturdy. ）

A small straight stick is used as a bow drill. Use a knife to rest the edges at the top and sharpen them at the bottom. In the middle of the lower position, it is best to draw a groove around the rope.

A cork base is also needed to be used as a drill floor. This is best done with combustible wood. Wang Xiaotie chose a four-finger-wide branch of a dead pine tree.

In order to increase the success rate of making a fire, Wang Xiaotie deliberately used a knife to collect a lot of pine resin on the larch, which is the gasoline in nature.

In the smoke, Wang Xiaotie's head also overflowed with beads of sweat. The vigorous movement made his body start to heat up.

Wang Xiaotie took off his coat and put it aside. If the fire does not start, then sweating is tantamount to suicide.

In three hours of unremitting efforts, Wang Xiaotie finally got angry, and the moment the fire burned, he was so excited that he couldn't even care about the fatigue and tiredness of his body, so he jumped up directly on the spot and yelled happily.
