Early the next morning, after breakfast, everyone hurried out the door.

They planned to find an outlet from the downstream first, because after all, the paper boats and foam boards that Xia Lingling was experimenting on had disappeared from the downstream.

For the next thing to do, Xia Lingling made detailed arrangements, and counted the total amount of food in the two shopping malls, which was almost enough for seven people to eat for more than a month. The first ten days are to find a way from the downstream, and the middle ten days are from the upstream to find a way, if neither of these two works, there will be at least ten days or so left for everyone to find other entrances.

After arranging the time, Xia Lingling made another manpower allocation, Jin Nanjun and Tian Zhengguo were responsible for collecting firecrackers in the city, Xia Lingling and Jin were surveying and analyzing along the riverside, and Zheng Haoxi, Suga, Jimin and V were responsible for collecting cement and transporting it to the river.

Xia Lingling and Jin first walked as downstream as possible along the river, and the river bends and stretches out, giving people the feeling that no matter how they walk, they can't reach the end.

The two of them braved the sun until noon, and did not find the end of the river, and finally they were tired, so they had to find a shade to sit down and rest, and eat some snacks that they had brought with them.

Taking advantage of the time when Jin was resting under the tree, Xia Lingling wandered around the river for a while, and she found that the further downstream she was, the more loose the soil became, and when the two of them rested, the soil around the river bank was a little wet, and it looked like it was soaked by the river water.

The two of them drew the direction of the river and the landform by the river on the road, and drew all the landforms by the river in their notebooks, and re-observed the places they remembered unclearly, and when they were ready to go back.

With this done, the sun was already setting to the west, and they got up and continued downstream, until the sun had almost set and they finally saw the end of the river.

The end of the place has been passed on foot, and the banks of the river within a radius of several tens of meters are all wet mud. Xia Lingling picked up a stone and threw it vigorously, the stone was quickly swallowed up by the silt, and the place where she threw the stone returned to its original state at a speed visible to the naked eye.

"There may have been a swamp over there."

The two glanced at each other, both seeing the helplessness in each other's eyes, it seemed that things were much more difficult than imagined.

The way back was relatively silent, because there was no need to stop at any time to observe the landscape and make notes, so the time was relatively short, and it was only a few hours before I returned to my accommodation.

When she entered 606, several other people were sitting at the dining table and waiting, there were few meals on the table, almost everyone was guarding a bowl of rice and a small plate of pickles, and only Xia Lingling put two steamed buns for her.

Xia Lingling was not polite, she just sat down and picked up the steamed buns and gnawed them, only ate a few biscuits at the end of the day, she was really hungry, and no matter how simple the food was, she stuffed the two steamed buns into her stomach after a while.

The people at the table looked at her embarrassed eating, they were all dumbfounded, the first time they saw Xia Lingling eating so desperately, just like a beggar who had been hungry for many days suddenly saw the feeling of eating.

Jin saw that she was choking, and hurriedly unscrewed the mineral water on the table and handed it over, Xia Lingling took it and was about to pour it violently, but as if he thought of something, he immediately took a few sips.

In the days that followed, not only would food become scarce, but there would also be less and less water to drink, and she really couldn't afford to waste anything.

When everyone saw that she was full, they all picked up chopsticks and prepared to eat.

Xia Lingling sat at the table and watched them keep letting their pickles go around, and suddenly felt that his eyes were hot, and he had the urge to cry.

She had always known that the members of BTS were the most united of all the groups, but now that something really happened, she found that they were much more united than she imagined. This kind of feeling, this tacit understanding, is completely beyond the existence of friendship, a kind of family affection similar to family that binds everyone together.
