At this moment, Zhao Yan was carrying a huge bag on her back and trekking hard in the desert. Sweat poured out, and was slowly dried by body temperature and the scorching sun. Zhao Yan didn't know that her clothes had been converted between dry and wet several times, she only knew that the twenty kilograms of mineral water she brought had consumed nearly ten kilograms, which was less than half a day.

Zhao Yan knew the importance of who was in the desert, so she prepared a share of ten catties per day for herself, and the extra ten catties were considered as a backup, but as soon as she entered the desert. She found out that she was completely wrong, and she couldn't have been more wrong. The dry heat had dried her body of water in barely an hour, and she felt extreme thirst, unbearable thirst. Bottles of water were poured into her, and after a while, she was thirsty again. It's like a leaky bottle that can't store a little water.

"You have to control yourself, you have to control it. Zhao Yan secretly cheered herself up in her heart, "If you continue to indulge, I'm afraid you will die inside, and you won't even be able to survive until the master comes to the rescue." ”

Zhao Yan looked up at the scorching sun in the sky, then lowered her head and looked at her watch, it was only one o'clock at noon, seven hours before the sun set, damn it, there were at least seven hours left, and she had only walked fifteen kilometers.

Zhao Yan calculated for herself that with the consumption of physical energy and the reduction of drinking water, her daily itinerary must be decreasing day by day, so if you want to complete the task, you must walk a hundred kilometers in three days. On the first day, it is best to walk fifty kilometers, at least forty-five kilometers, and then, on the second day, it is thirty or thirty-five kilometers, and the third day must be the most difficult, so Zhao Yan only left a plan of twenty kilometers for the third day.

The ideal is very plump, and the reality is very skinny. One-third of the first day has passed, and I have only completed less than one-third of the plan for the first day, you know, this time is the time when my physical fitness and water are the most sufficient, and now I have only completed one-third, what should I do with the rest of the trip.

"No, I can't slow down anymore, I have to keep going, at least keep the speed. Zhao Yan cheered herself up. Step by step, heavy steps.

The sun seemed to be fixed in the sky, and Zhao Yan felt that a long time had passed, but when she looked up, the sun was in the sky. After a long time, she didn't dare to look up at the sun, she was afraid that after seeing too much, her confidence would slowly collapse.

She buried her head and walked forward step by step, she kept telling herself that if you take one more step today, you will be able to take one less step tomorrow. In the desert, which was a little charred by the sun, a lone figure, carrying a huge package, step by step, behind her, were two long strings of deep footprints.

Lin Raorao stood in front of the window, wearing light clothes, enjoying the refreshing coolness of the room, but she couldn't be happy. She knew that in the distant desert, her sister who loved her was undergoing unbearable tests for ordinary people.

"Senior sister, you must hold on, the sun is about to set......"

Zhao Yan gasped, if someone stood in front of her now, it would be almost impossible to recognize that this was the Zhao Yan who could be called peerless before. Her hair had lost its original black shine, and had become a little yellow and dry, as if it had been burned by fire. Her face, scorched by the scorching sun for most of the day, had already appeared an unnatural burnt yellow. The biggest change is the lips, which were originally moist and pink, but now they have become pale, and a layer of dead skin on the lips has quietly formed at some point.

Zhao Yan didn't look at her watch, she didn't look at the sun, she just walked with her head down, step by step. It's not that she doesn't want to see it, but she doesn't dare to watch it, she is afraid that after she sees too much, she will lose confidence by her slow progress, she tells herself to wait more, wait more, and there will be surprises when she sees it.

She walked in a trance, only occasionally looking at her compass to make sure she was heading correctly. She doesn't look up, she always only looks at the three-foot ground under her feet, even when she puts down her bags to find water to drink, she only looks at her backpack, and she doesn't want to raise her eyes to see even a meter more.

Gradually, she had forgotten that she was in the desert, and only felt that she was walking a road with no end. The road is yellow and scorching......

I don't know how long it took, the color of the road seemed to change a little bit, it seemed to become a little darker, she didn't know why, and she didn't want to think about it.

Gradually, the color of the road changed from light yellow to dark yellow, then to orange yellow, and then there was a hint of red in the city god, and gradually, more and more red, deeper and deeper. Then, the red slowly faded, and gradually, the road under his feet was only yellow, but this yellow was a little different from the memory at the beginning, it seemed, it seemed that it was not so bright, and it was a little less hot.

Wait, a little less scorching, Zhao Yan suddenly raised her head and looked at the sky. The scorching sun had long since disappeared, and the sky had begun to slowly darken.

"Has the sun set?" Zhao Yan slowly lowered her head and looked at her watch.

"At twenty-thirty-six, it was finally getting dark. Zhao Yan muttered to herself. Then, a strong desire came to her mind to see how many miles she had traveled.

Slowly and hesitantly, she pulled out her phone and lit up the screen.

"Forty-three kilometers!" Zhao Yan was overjoyed in her heart, and at the same time breathed a sigh of relief, she raised her head and looked around, moving her neck, which was a little wooden because she had walked with her head bowed for a day.

"Well, now that the temperature is not that high, I have to walk another seven kilometers and rest after completing today's goal. Zhao Yan secretly cheered herself up in her heart. However, when she took a step, she found that her legs were as if they had been filled with lead, and she could barely move. It's like a long-distance run, and once you stop, it's harder to run again.

"Otherwise, let's rest, 42 kilometers is enough! If you rest today, you will be more energetic tomorrow. In Zhao Yan's heart, a voice sounded quietly.

"No, you can't rest, you must complete today's goal!" Another tougher voice instantly overshadowed the previous voice, Zhao Yan bit her lip and took the first step with difficulty, and then, the second step......

She felt pain all over her body, her bags behind her were like a mountain weighing her down, and her legs were even more useless, almost unresponsive, but she still didn't try her best to sell her steps.

One kilometer, two kilometers...... It was slowly getting dark, and after five kilometers, it was already dark. Zhao Yan didn't care about it, and still walked forward slowly but firmly.

"Three more kilometres, just three kilometres. Zhao Yan kept telling herself in her heart.

When the distance on the mobile phone was displayed as fifty kilometers, Zhao Yan finally lost all her strength at once and fell to the sky.
