Yao Xinyan didn't remember how long they had walked, and in the end she couldn't walk, so Lin Hong carried her on her back and continued to walk. Because she was too tired, she fell asleep on Lin Hong's back. When she woke up, Lin Hong told her that they had arrived, and that they were in a stone cave, which was much more luxurious than their previous two "homes".

"Hong, is this our new home in the future?" Yao Xinyan asked.

"If nothing else, this was our home before we left, and I found a lot of good things in it. This is where the people who used to come live, and they left us with a lot of hope. Also, I met a new friend. His name is Li Shen, he is a geologist, and he is on your right hand right now. Lin Hongdao.

When Yao Xinyan heard that there were others, she was very surprised, she didn't feel the breath of a living person. But since Lin Hong said it, she still said hello. "Hello, I'm Yao Xinyan."

"You don't have to say hello to him, he's just a pile of bones."

"Ah~" As soon as Lin Hong's words fell, Yao Xinyan screamed in fright, stood up and rushed in the direction of Lin Hong. In the end, she caught Lin Hong, curled up in Lin Hong's arms, and trembled: "Get out, get out." ”

"Don't be afraid, it's just bones. In fact, after we die, we are just like him, and we are also a pile of white bones under our flesh and skin. You have what I have and what he has, so you don't feel scared when you think about it. I'll bury him later, he gives us hope anyway. In his diary, I found my way out. Lin Hongdao.

"What's going on? And why do you know that his name is Li Shen and he is a geologist? Yao Xinyan asked.

"Because of this diary." Lin Hong shook the diary in his hand and said, "According to the records, they entered Lingshan ten years ago. There were three of them, but unlike us, they came straight down from a large hole in the mountain, and eventually they couldn't get up and were trapped inside. But the three of them brought down a lot of tools and materials, and after exploring the place, they began to figure out how to get out. Eventually, they used the materials and tools they had brought with them to make a hot air balloon, but because it was a small hot air balloon, it could only carry two people. In the end, they used a lottery to choose one person to stay, and the other two went out and asked for rescue. Unfortunately, he was the last one to stay. On the day of his two companions' departure, an accident occurred when the hot air balloon was about to fly off the ground, and the last two companions were killed. And he's trapped here, and no one knows. After living alone here for three years, it felt like no one would come to save him, and I didn't think anyone would come to such a place. He couldn't stand the loneliness and ended up committing suicide. Inside the diary is a badge of his work with his name and occupation on it. Lin Hong explained to Yao Xinyan.

"Where's the hole you said you could get out of with a hot air balloon?" Yao Xinyan asked.

"The diary says very clearly, due north. It is said that the diameter is just over three meters, and the hot air balloon rubbed against the cave wall along the way, so it finally caused it to burst, killing two of his companions. But no matter what, you can get out of that hole. Lin Hongdao.

"Due north, do you know where the north is now?" Yao Xinyan asked.

"Of course." Lin Hong said proudly: "I said it, they left us hope, they are geologists, and they are here to investigate." In that case, how can you do without a compass? In this cave, I not only found a lot of tools, but also found a compass, which I can use. ”

"That's right." Yao Xinyan smiled gloomily. It seems that this can't stop Lin Hong from going back, and to put it bluntly, Yao Xinyan doesn't want to go back. The world of only two people, she felt good. There are only the two of them in this world, and that's enough.

"I'll go and bury Li Shen and let him be buried in the ground. Then I went to sleep, and I went to look for the hole. And find the original hot air balloon, repair it, maybe it can still be used. That way, we'll be able to get out. After Lin Hong finished speaking, he had already gone out with Li Shen's bones.

The ground is hard, so it's impossible to dig a hole and bury it. Not to mention that there are no such excavation tools, and even if they do, I don't know how much time it will take. So Lin Hong used the rocks to pile up a simple stone tomb, and then put Li Shen's skeleton into it.

Standing in front of the stone tomb, Lin Hong clasped his hands, closed his eyes and said, "Li Shen, you owe me a favor anyway." So please bless us to get out safely. After finishing speaking, Lin Hong returned to the stone cave, lay down, and began to study Li Shen's diary.

Looking at it, Lin Hong couldn't help but want to laugh. Of course, it was not because Li Shen wrote it funny, but because Lin Hong found that there was huge wealth and business opportunities in this diary. Because Li Shen wrote down everything he had seen and heard in the underground world for more than three years, including the role of some plants, all of which were recorded. I don't know if I don't look at it, but after I look at it, Lin Hong finds out. The underworld, where he is now, turns out to be a huge treasure trove. In it, it's all genius treasures. Let's not talk about some fossils, but the plants in them are almost all treasures. If these plants can really be cultivated on the ground, it will be difficult to think of underdevelopment.

When he woke up, Lin Hong stretched his waist. At this time, Yao Xinyan was sleeping in his arms, Lin Hong didn't disturb her, and waited until she woke up before he said to Yao Xinyan: "Xinyan, I'll go prepare food for you, and then I'm going to look for the wreckage of this hole and the hot air balloon." You have to wait for me here obediently, and you must not be naughty. ”

Yao Xinyan lowered her head, wanting to say something, but she didn't speak, and finally she nodded.

After preparing food for Yao Xinyan, Lin Hong set off, taking his diary and compass with him. As for the food, don't worry about it at all, it's basically everywhere.

Lin Hong didn't know how long he had been walking, and the scenery in front of him had not changed, but what hole was mentioned in this diary, the hot air balloon was completely nothing. This made Lin Hong feel very strange, it was written very clearly in this diary. The entrance to the cave was directly north of where they lived, more than ten miles away. But Lin Hong had walked for at least twenty miles, and he hadn't seen any caves. Lin Hong opened the diary again to make sure, yes, it's due north. While looking at the compass, there is nothing wrong with their direction, but strange, why is there no cave? It can't be that he was deceived, but it's impossible to think about it, he is trapped here, and I don't know if anyone will come in the future and write a fake diary to deceive people? It's not realistic, but what exactly is wrong with this?
