In the end, everyone accepted Fang Jinyan's point of view, and as he said, it is always right to be cautious.

However, Zheng Chen still did not give up, and asked to investigate the other party's situation immediately, no matter who it was, it was always right to find out.

Fang Jinyan and the others could understand his feelings, and they themselves felt that this might be an opportunity, so they agreed to his request.

"But the question is, now that we only have one button, how can we find their traces?" Zhao Lan asked.

"Let's go where you found the buttons, maybe there will be other clues." Zheng Chen said.

"yes, it's raining almost every day these days, so maybe you can find some footprints." Zhang Hongbing also said,

"Not necessarily, the ground there is mostly stone, and the rest of the place is mostly grass, so it is not easy to leave footprints, if there is, we should have seen it just now." Zhou Rong shook her head and said.

"It's also said that we rarely leave footprints when we are active in this area on weekdays, even if there are some that are not very obvious, the rain is so heavy, it is easy to wash away, thanks to this, otherwise the other party may enter this area, it is easy to find traces of human activities here, so we are passive," Zhao Lan said.

"Yes, we'll have to pay more attention in the future." Zhu Pingzhi supported, "Try not to leave too obvious footprints, and at the same time, try to do as much camouflage as possible on the side of the treehouse, so that no one else can easily discover our base camp." ”

"So what are we going to do now?" Zhu Qianqian asked in confusion, her eyes looked at Fang Jinyan, obviously hoping that he would come and get an idea.

"Zhou Rong. Why don't you take us there? Fang Jinyan said to Zhou Rong.

"There really aren't footprints, I've just noticed. I observed a large area, and there were no traces of any footprints," Zhou Rong hurriedly said.

"It doesn't have to be footprints. It could be something else. Fang Jinyan said.

"What else could there be?" Zhou Rong asked puzzled.

"I don't know, I only know when I see it." Fang Jinyan said.

"Well, you can do whatever you want." Zhou Rong said a little depressed.

"I'm sorry for you, it's not very far anyway." Fang Jinyan didn't seem to feel her affection, and was very polite as always.

It is indeed not very far, Fang Jinyan followed the footsteps of Zhou Rong and other girls, and soon arrived at the place where the button was found.

"This is here, you see this ground, it's all hard lava stone, how can it leave footprints." Zhou Rong stepped on it a few times with her foot and said.

Fang Jinyan did not answer her. Just glanced at the ground a few times, then frowned.

"What's going on? Did you find anything? Zhou Rong hurriedly asked.

"This button may not have been lost here." Fang Jinyan replied.

"What does this mean? I don't understand. Fang Jinyan's thinking has always turned too fast, and the others can't keep up.

"The terrain here is a bit lower than on both sides, and when it rains, the water from the higher places collects here and then flows lower down." Fang Jinyan reminded.

"Oh I see, you mean, this button may have been brought in from somewhere else by the rain!" Zhou Rong's brain is still a little faster than others. Finally reacted.

"Well, that's right." Fang Jinyan nodded and said.

"No wonder, I said it's so close, we scout every day. If anyone was passing by, we didn't see them at all! And they've all arrived here, how can they not see those baobab trees," Liu Yun said.

"You're right. I also felt that they couldn't have been around before, so I decided to come and have a look. Fang Jinyan said.

"So what are we going to do now?" Zhang Hongbing asked again.

"Do you need to ask? Traces of flowing water, of course. Reverse tracking upstream, so you might be able to find more obvious clues! Zhou Rong said.

"You don't count. You just said that you won't come here to see it, I'll listen to Brother Fang. Zhang Hongbing was unhappy with her tone and deliberately mocked her.

Zhou Rong panicked in an instant.

"This time she said it works, let's give it a try." Fang Jinyan said.

"That's okay, let's do it, I've finally been blinded by her once." Zhang Hongbing said very simply.

Zhou Rong instantly wanted to kill

So everyone took action and began to search upstream, which is not a very difficult job, mainly based on the terrain can be judged, and the rain washed over the area, there will always be some traces, such as a small amount of fine sand and so on.

However, this waterway, which only flows when it rains, has several sources, and they have to trace them one by one, which wastes a lot of time, but in the end, they still find something.

In a small puddle where the rainwater had not had time to evaporate, Fang Jinyan found a glass fragment in the sand layer that had been precipitated underground, which was obviously also retained in the rainwater erosion process.

"There is also a pattern on it, a flower seems to be a fragment of a water cup, it seems that there must be someone on it." Zhao Lan immediately became nervous and said.

"Well, everyone be careful, be ready to fight at any time, of course, it's better not to let them find out about us and avoid conflicts." Fang Jinyan Yan said.

Well, although he has always been strict, now it feels a little stricter.

"Understood!"

Everyone's hearts were tight, and then they followed Fang Jinyan's words and continued to carefully recommend in the upstream direction.

Eventually, they found a cave, and it seemed that there was a spring flowing out of the cave, but the amount of spring water was not large, and it soon seeped into the cracks and layers of sand, which means that the water could not flow downstream, and only when it rained, the spring water mixed with the rainwater and flowed downstream.

"Pay attention to the tree over there, there are traces of being cut by an axe, it seems that there should really be people living in this cave, at least someone once lived." Fang Jinyan reminded everyone in a low voice.

Everyone looked in the direction he pointed, and in the inconspicuous bushes in the distance, there was indeed a remnant of a stump, the cut of which had a special sense of layering, and only an axe could cut this effect.

"The wood is rotten, and even fungus has grown on it, and it looks like it's been cut for a while." Zhou Rong said in surprise.

"Well, that's why I said, it's probably just once inhabited, but it's not necessarily, wood decays very quickly during the rainy season, sometimes in a month." Fang Jinyan said. (To be continued......)
