The morning sun in Beijing shines through the light clouds, shining on the golden earth, reflecting the golden light, which makes people feel particularly comfortable. Li Tangshan got up early and began to prepare, in fact, there was nothing to prepare, the organizing committee required that he could only bring a Beidou locator, a dagger and some easy-to-carry items that were attached, and those that were not allowed by food. Food supplies can only be found 200 kilometers away yesterday.

Li Tangshan has conducted field training with Uncle Zhuo in the tropical rainforests of Southeast Asia, and still has some experience in cross-country and wilderness survival.

Li Tangshan summarized some off-road-related knowledge, and generally paid attention to a few details:

In terms of wearing, you should choose comfortable and thick-soled shoes, such as hiking shoes, plus two or three pairs of socks to ensure that your feet do not bubble on long journeys; Durable and loose trousers, perfect for trekking through the jungle; A sweat-absorbent, breathable, and soft T-shirt is the best, so prepare a replacement or two.

There will be snakes in the mountains in summer, so don't wear shorts to go up the mountain; There is a large temperature difference in the mountains, so adding a coat in the morning and evening can resist the mountain wind; In summer, it is rainy, and the mountains are cloudy and sunny, and the raincoat is an indispensable defensive tool; There are often places to swim in the mountains, so it's a good idea to bring a swimsuit, swim trunks and a waterproof bag.

"Tick..... The "Tick ....." rallying call has sounded.

Li Tangshan picked up his backpack and quickly came to the designated place.

The staff asked each participant to open their backpacks to check the materials inside, and the staff looked very carefully, slowly confirming whether there were any prohibited items in each bag.

The staff found two books on the field from Hong Tiejun's bag, as well as a pile of compressed biscuits. He waved his hand to Hong Tiejun, indicating that these are all products that are not allowed to be carried.

The staff checked Li Tangshan's backpack, and there were no contraband in it except for some daily necessities, and the staff still took out the turned off mobile phone he put in the bag and labeled it with his name.

The workers also checked Huang Fuxing's backpack, which contained too many items, including various electronic products, game consoles, and solar chargers. There is also an improvised tent and moisture mat. Li Tangshan, who was on the side, was stunned when he saw it, and said in his heart: "Brother, are you going on vacation?" ”

Huang Fuxing asked the staff to leave him a video game or two: "Off-road is too boring, so I'll use them to pass the time." ”

The staff smiled: "We'll keep it for you and return it to you when you finish the task." He said and carefully labeled each electronic device with its name and registered it.

The staff checked Huang Fuxing's backpack and began to check Cao Yan's backpack. Cao Yan didn't have a lot of things in his backpack. The staff just took out a bundle of cash from Cao Yan's bag. Staff: "Cash and bank cards are not allowed. According to the regulations, we will help you keep it and return it to you when you complete the task! Please sign this registration form. ”

Li Tangshan, who was on the side, saw that Cao Yan's face was quite ugly, as sad as his dead father, and there were tears in the corners of his eyes.

The workers will register the illegal items that have been removed, and ask each one to confirm that they are correct and sign the form to ensure the fairness of the competition.

After checking their backpacks, the staff made an OK gesture to the expert group.

The leader of the expert group came over to a few of them and said loudly:

"Students, before I go, I want to talk a few words.

1. Pay attention to life safety, the location of this wild survival competition is carried out in the Taihang Mountains, and the terrain is diverse and very complex. Although you all have relevant training experience, paying attention to safety is the most important thing, and if you encounter something life-threatening, you must not do it. Your Beidou locator has a red distress button, and our rescuers can arrive within 20 minutes, but it also means that you have to quit the game.

2. Still emphasizing organizational discipline and rules, the purpose of this competition is very clear is to test your executive ability in an extreme environment, the competition can only be carried out in the designated no-man's land, and it is not allowed to interfere with the lives of the people, and all living materials can only be obtained in nature. Once violators are found, they will be eliminated directly.

3. The last one is very important, which is to wish you all good luck. Hahaha!

The leader of the expert group laughed, and then said to the staff, "Then let's start!" ”

The workers explained the rules of the game in detail. After instructing the trainees to get on the bus, they asked the driver to drive in the direction of the destination Jingxi Eighteen Ponds.

The car carrying Li Tangshan and them quickly arrived at the designated place.

Staff: "Everyone, pay attention, your starting point is about to be fast, everyone check whether your backpack and GPS are normal, and you can go immediately!" Everyone must pay attention to safety! ”

The car stopped slowly, and the staff pointed to the path in the woods of the Eighteen Ponds in the west of Beijing and said: "The students have arrived, you can go!" ”

Li Tangshan and the four of them jumped out of the car and quickly disappeared like the wind into the woods of the Eighteen Ponds in the west of Beijing.

Li Tangshan thought to himself as he walked: "At a speed of 50 kilometers a day, you have to walk for at least 10 hours a day, this speed is still too slow, don't worry about it for now, let's find a way while walking!" ”

Here, Cao Yan ran over and said to Li Tangshan: "Brother, this time I thought I would spend some money to solve the problem of food and clothing, so I didn't prepare anything." You can help me a lot when you get there. ”

Li Tangshan nodded to Cao Yan.

Cao Huo happily patted Li Tangshan on the shoulder, and then chased after Huang Fuxing and them.

Li Tangshan didn't pay much attention to Cao Yan, and kept thinking about how to quickly and safely arrive at the destination Handan Airport.

Li Tangshan found that the path ahead was slowly becoming more and more difficult to walk, and many roads were submerged in weeds.

Li Tangshan knew that he had entered the Taihang Mountains, and Li Tangshan realized that this place was very different from the tropical rainforest. Taihang Mountain belongs to the warm temperate semi-humid continental monsoon climate, and now in July, the temperature is also about 23 degrees, which is very comfortable.

Li Tangshan also professionally consulted relevant materials last night. Towering 800 miles of Taihang, from north to south through the heart of the Chinese land, up to the Yan Mountain, down to the Qinling Mountains, is the North China Plain and the Loess Plateau geographical demarcation, but also the third ladder of China to the second ladder of the natural leap. It has played such a very important role in Chinese history that it has been called the "spine of the world" by historical geographers.

The main vein of Taihang Mountain extends for more than 400 kilometers, and the total length is nearly 1,000 kilometers. The average altitude is 1200~1500 meters, and the highest peak of the main vein is located in the eastern platform of Xiaowutai Mountain, Hebei Province, with an altitude of 2882 meters. It is customary to divide the Taihang Mountain into three parts: South Taihang, North Taihang, and West Taihang, which refer to the Taihang Mountain in Henan Province, Hebei Province, and Shanxi Province respectively.

The formation of the Dahang Mountains occurred about 1.8 billion years ago, and the "Luliang orogeny" caused the paleoland masses in this area to enter the stage of differential uplift, and the Taihang Mountains began to sprout on the seabed. Subsequently, under the action of the "Yanshan Movement" and the "Himalayan Movement", this area of thick sandstone layers was uplifted several times, and finally uplifted 2.4 million years ago and uplifted into today's Taihang Mountains.
