1. In cold and thin air, helicopter flying can be dangerous, so the way to land is to use a paraglider to fly over the Andes with the help of updrafts.
2. It is difficult to move at high altitudes. At an altitude of more than 3,000 meters, the oxygen content is 15% less than that at sea level.
3. When the warm air in the tropics rises to about 2400-3 kilometers, it will condense to form clouds or rain, so it is called cloud forest. It's quiet around, you can't hear anything but the crackling rain. Everything here is very damp and seems to be rotting.
4. The cloud forest is much richer than the grassland, and the temperature and humidity conditions make it home to thousands of different species of animals and plants.
5. Caecilians usually live underground and feed on earthworms, spiders and insects. But because it's so humid and raining too much, they'll be forced to run to the ground, even though they look like snakes, they're actually legless lizards that look edible, but the threads under their skin It contains toxins and cannot be eaten.
6. Cougars and snakes will live in such forests, but are rare and deadly plants. The leaf-eared rat mushroom is poisonous, if eaten, it will destroy your kidneys within 24 hours, it is very deadly, and once eaten, there is no antidote or cure. Unless you're a mushroom and toadstool expert, it's best to stay away from mushrooms.
7. If, on the way down, the dense undergrowth suddenly gives way to a narrow passage all the way to the ground, it may be caused by water erosion over hundreds of years. It's like a highway through the jungle that might lead you to a river.
8. Generally, caves are forbidden areas, and there will be bats in them. They were all excellent aviators, all relying on sonar to fly. If bitten by a bat, they could be carrying the rabies virus. And the stench in the cave was unbearable, with bird droppings and bat droppings everywhere. The smell is also highly poisonous and a breeding ground for biting insects, so be sure to get out of the cave quickly.
9. The sound of the water crashing is getting smaller and smaller, which means there is a rapid current. The rapids here run down the snow-covered Andean summits, and they're freezing cold, they're very turbulent, and you have to be very careful when walking along the banks, because they're slippery.
10. Brown-spotted yellow orchid is easy to identify, it is yellow with brown spots on it, and its biggest advantage is that it can satisfy hunger. In the cloud forest, there are thousands of plants that are edible. Flowers can quickly replenish blood sugar. Immature fern leaves are also edible, and the nearby natives will harvest these for food, you can identify them by the shape of the monkey's tail, and the surface is covered with creepy thick mucus, but this mucus is only To protect yourself from being eaten by bugs. Boil it twice before eating to remove the toxic mucus. Failure to do so can lead to severe stomach cramps.
11. If you want to cross the swift stream, you can use two long bamboo poles to make a ladder, and then use vines to tie some small saplings to make cross braces, and rely on the ladder to reach the other side of the river. Choose fresh, live vines. If they are dry, they will break easily and have no toughness. Linglang rattan is a very good material, strong and flexible. Although this kind of bamboo is hollow, it will be very heavy if it is made that big, maybe more than 130 catties, so it needs to be built nearby.
12. It may seem impossible to find dry fire in a humid environment, but you can find it if you know the trick. You can look around, if you find rabbit dung, and rabbit tracks, you can find a rabbit nest, they will dig a hole under the grass, and in the hole you will find hay. 13. Wet hay won't ignite, but it can be tucked inside a shirt and used as insulation. These grasses act like fluff, preventing most of the heat loss.
14. Rain will distract you and make it easier for you to approach them.
15. You can make your own bow and arrow for fishing. Castanopsis is a very good wood for bows and arrows, it is very hard and allows you to split the wood lengthwise. The local Huaorani people have refined this method over hundreds of years, especially for shooting fast-swimming fish while diving. An easy one can be made, just chisel a few grooves at the ends so that the bowstring can be tied. Pita brown leaves contain long fibers that are perfect for bowstring material, but it has nasty little burrs from top to bottom, which need to be shaved off first and then broken apart to remove the fleshy part of the leaf from the tough. The rear part is separated. Then just tear one off, put it in your mouth, and start weaving, braiding them together, which adds to their strength and durability, since it takes a lot of pressure to fit on the bow. Then tie a simple single tack on both ends. Arrows are made of the same kind of wood as bows, so that they can pass through water with excellent performance.
16. If the waters are populated by aggressive piranhas, it will make hunting and fishing more difficult. Water Margin fish are very ferocious, they can tear up animals that fall into the water in seconds, and they will tear up people, but this only happens when they encounter a school of more than 100 piranhas. A small pond cannot hold so many fish, so it should be safe to go into the water. Piranhas are delicious but hard to catch, they are very fast. Find some shallow water where you can see what's under the water. If a jungle pond can be found and its water level is dropping (you can see by the shore where it has been), it means that fish will be trapped in such a pond, it is shallow, it is most likely to catch fish The place. Be sure to cook piranha thoroughly before eating, as they carry harmful parasites.
