After Shang Jia finished talking about his solution, the three of them also nodded in agreement, and after the four of them began to find the stump and carefully observe the tree's annual rings, the four of them continued to walk through the fog.

As if God had added difficulty to the students, the fog was getting bigger and bigger, and the visibility was less than ten meters. Yu Xiaoshuang was accidentally distracted and gradually broke away from the team. When she realized it, there were no people around, only a white mist.

She shouted the names of Xia Sangyu and Liu Menghan loudly, but she didn't respond for a long time. Yu Xiaoshuang sat helplessly on the ground and couldn't help crying.

Xia Sangyu didn't notice that Yu Xiaoshuang was missing at first, until Xia Sangyu felt that the visibility was too low and wanted to tie several people together with a rope to avoid getting separated. At this time, half of the time has passed, but due to the weather, the few people have not walked a third of the distance, if they go back to find Yu Xiaoshuang, the time behind will definitely be very urgent, and no one can guarantee how long it will take to find Yu Xiaoshuang.

Xia Sangyu thought for a while, it would definitely not work to leave Yu Xiaoshuang, but it would undoubtedly be a waste of time for everyone to return, so she decided that she would go back to find Yu Xiaoshuang, and Liu Menghan and Shang Jia would take the lead.

It's just that the first person she didn't expect to be right was Shang Jia: "No, we want to go back and we go back together, we are a group, and none of them can be left behind." ”

Liu Menghan also hurriedly nodded in agreement: "Yes, we want to live together." After speaking, he was afraid that Xia Sangyu would not agree, so he immediately ran from the direction he came.

Xia Sangyu ran a few steps and grabbed Liu Menghan and said helplessly: "I'm really convinced of you, I didn't say I disagreed." What are you running, usually you are so steady, why are you so reckless. If you get lost, we won't be looking for you. ”

Liu Menghan also realized that his behavior just now was indeed too reckless, and he stuck out his tongue at Xia Sangyu embarrassedly: "I'm not in a hurry." ”

Xia Sangyu connected the three of them together with a rope, carefully discerned the way they came, and shouted Yu Xiaoshuang's name as she walked, but fortunately, she didn't walk long to find Yu Xiaoshuang who was still crying on the ground.

Yu Xiaoshuang was crying helplessly, when she suddenly heard someone calling her name and responded tentatively. Vaguely seeing Xia Sangyu and the others appear in front of her, Yu Xiaoshuang immediately got up and rushed towards Xia Sangyu and Liu Menghan, hugged the two of them and cried and asked, "Why did you come." I'm left alone, and I'm scared to death. ”

Xia Sangyu patted Yu Xiaoshuang's spine comfortingly, since Yu Xiaoshuang's mood was still unstable, Xia Sangyu proposed to rest here and settle lunch by the way. After some trimming. The strength of the people was restored. Yu Xiaoshuang's mood also stabilized, and Xia Sangyu spoke: "Now we have to hurry up, Xiaoshuang hurriedly tied the rope to her body, and don't leave the team this time." ”

Yu Xiaoshuang took the rope and tied herself firmly to the end of the rope, and the four of them advanced to the designated place again, perhaps God felt that a few of them had passed the test, and at four o'clock in the afternoon, the fog gradually dissipated. Visibility gradually restored. Several people stopped, corrected their direction, and continued to speed forward.

There were less than two hours left before the allotted time, and a third of the distance was still a third of the way for several people. Along the way, Xia Sangyu and Shang Jia were a little better in physical fitness, and one pulled one to move quickly.

After another rapid march, the four of them finally ran out of the dense forest and saw a sign set up at their destination in the distance. I ran along the sign. As soon as I ran around a corner, I was blocked by the wall in front of me.

The four of them stopped in unison. Xia Sangyu carefully observed the surrounding environment, and saw that there were steep stone walls on both sides, and the only way to pass through was to climb over the wall.

Xia Sangyu immediately decided that the four of them would rest on the spot, recover their physical strength and climb over the wall together, none of the four people arrived at this place during the break, and there was silence around, Xia Sangyu looked at his watch, there was only less than half an hour left before the specified time, and he didn't know what difficulties were waiting for them to climb over the wall, time waits for no one, and he can't spend it here, Xia Sangyu took the lead in getting up and running a few steps with the help of inertia, suddenly jumped up with both hands, climbed up with strength on his feet, and finally turned over and rode on the wall.

At this time, Qi Yiyao and Wang Yang were already standing at the end of the line, and saw Xia Sangyu, she was the first to arrive in the girls' team, seeing that there was not much time left, Qi Yiyao was also a little anxious, what was Xia Sangyu doing, she had already climbed the wall, why didn't she come down, was it too high to go down, shouldn't it.

Chen Yixuan, who had already reached the end of the line, also saw Xia Sangyu's actions, and after a little thought, he guessed why Xia Sangyu hadn't come down yet.

At this time, Xia Sangyu was encouraging Liu Menghan and Yu Xiaoshuang, so that they could climb bravely, and everything was with her. And Shang Jia is not worried, she knows that although the height of this wall is a little difficult for Shang Jia, it can't stop her pace, the reason why she hasn't come up yet is to help Liu Menghan and Yu Xiaoshuang and then she is climbing the wall.

With the encouragement of Xia Sangyu and Shang Jia, Yu Xiaoshuang took the lead in rushing towards Xia Sangyu, Xia Sangyu bent down and prepared to pull Yu Xiaoshuang at a critical moment, but she neglected Yu Xiaoshuang to be more than 20 pounds heavier than her, and she bent down on the wall and it was difficult to maintain her balance, so when she pulled Yu Xiaoshuang, she was pulled down the wall by Yu Xiaoshuang and fell to the ground.

Yu Xiaoshuang was startled, and hurriedly picked up Xia Sangyu and asked her if she was injured, Xia Sangyu supported her slightly with her hand at the moment she fell, delaying the fall, so there was no injury on her body, but the supported wrist should have hurt her tendons. Don't dare to move too hard.

Xia Sangyu was afraid that Yu Xiaoshuang would feel guilty, so she hurriedly said that she was fine. At this time, Liu Menghan and Shang Jia also ran over and asked about Xia Sangyu's injury, and they were relieved after learning that it was okay.

Liu Menghan sighed and said, "This is really half of a hundred miles traveler." ”

Xia Sangyu saw that Yu Xiaoshuang and Liu Menghan were a little depressed, and hurriedly comforted her: "Don't be discouraged, this is it, after this wall, we can reach the end smoothly, come on." ”

Xia Sangyu moved his wrist lightly and said to Shang Jia: "This time, you will go first, and I will help the handle below." ”

Shang Jia nodded, turned around and sprinted, when Xia Sangyu climbed over the wall just now, she also found a trick, so she didn't have too much effort to climb the wall. Yu Xiaoshuang didn't dare to go on again, so Liu Menghan went first. Xia Sangyu stood on the edge of the wall, ready to hold Liu Menghan when he climbed the wall, so as not to drag Shang Jia down again.

Liu Menghan climbed the wall with the cooperation of Xia Sangyu and Shang Jia, and Yu Xiaoshuang dared to climb again when she saw that Liu Menghan succeeded. Xia Sangyu struggled to hold Yu Xiaoshuang, and finally sent her over the wall, leaving her alone, Xia Sangyu rushed a few steps, and when she climbed the wall, her injured hand just now couldn't use her strength, and fell down again.

Shang Jia originally thought that Xia Sangyu didn't need help to jump off the wall after Yu Xiaoshuang, but after running a few steps, she found something abnormal, and hurriedly climbed the wall with the help of momentum again, when Xia Sangyu climbed again, she found an abnormality, Xia Sangyu's hands have not been strong, when Xia Sangyu climbed again, she grabbed Xia Sangyu's arm to help Xia Sangyu climb the wall, and the two jumped down together after looking at each other and smiling on the wall.
