The three of them walked about 500 meters, and a cave appeared in front of them, Jiang Xu looked at the entrance of the cave and frowned.

There are a lot of unusual footprints on the ground, and the reason why they are unusual is that the size of the footprints is much larger than the size of human footprints.

"There won't be any beasts here!"

Su Yang bent down and looked at the footprints on the ground, and said worriedly.

Qiao Jing and Jiang Xu both smiled slightly and looked at Su Yang.

"What? Are you afraid? I'm afraid you'll go back! Beasts are much kinder than people, single-celled, no intrigue, and no secret arrows to hurt people, if they want to eat you, they just stand in front of you and open their mouths, how good!"

Jiang Xu said, gesturing the marks on the ground with his hand, muttering to himself.

"It's not like the footprints of a beast, and in terms of texture, it's just a normal sole, but this size has to be almost 50 yards. ”

Qiao Jing squatted down and looked at Jiang Xu with a frown.

"It should be for some reason, special shoes, but if it is special shoes, then it is impossible to customize them in this deep mountain!"

Jiang Xu nodded, then stood up and pointed to the cave in front of him.

"I guess, there's even more caves in it!"

Ignoring the footprints on the ground, the three of them walked into the cave together.

The cave is really another world, Jiang Xu looked around, the cave was very simple, in addition to a thick carpet on the ground, and a dirty quilt, there was some garbage, Qiao Jing walked up, put on gloves, and then rummaged through the garbage.

Su Yang was not idle, he quickly put on his gloves and followed Qiao Jing to grope around, Jiang Xu kept showing doubts and walked around inside, Su Yang raised his head and looked at him, and sighed slightly.

"What are you doing walking around here?

Jiang Xu shook his head, and then walked to Qiao Jing's side.

"Doctor Qiao, look at the situation in this cave, what kind of person do you think will live in it?"

Qiao Jing stood up, walked around as well, and then sank his face.

"This person seems to live a very rigorous life, you see these garbage, although there are a lot of them, but they are all thrown in one place, piled up into a mountain but do not affect the tidiness of other places at all, and look at the quilt, maybe because of the long time, very dirty, but there is no smell in the cave, which shows that this person will take out the bedding to dry when the sun is out, and more importantly, it is the decoration of this cave, all things have a certain order and rules, and, more interestingly, this!"

Qiao Jing walked to a corner, and there were three books neatly placed in that corner, and one of them was still spread out.

"This person pays great attention to the intake of knowledge, or rather, he is born with a love of reading, and generally takes reading as an interest, with a wide range of knowledge, and a quiet personality, 80% of people who like to read books are more temperamental and connotative, which shows that this person is a very inner person. ”

Qiao Jing put down the book and laughed.

"There is a man who lives here, no more than 40 years old, with an average build, not very tall, and his movements should not be very agile, and the footprints on the ground are of different shades, and it looks like he should have been injured in his right leg or foot, and his personality is calm and introverted, which ...... It doesn't seem to be the same as we speculated!"

Jiang Xu smiled appreciatively, and then walked to the entrance of the cave.

"This cave is really interesting, if it were me, I might enjoy life here, but I don't think anyone will find this place for fun. Also, it is estimated that the reason why his shoe size is so big is because of what you said, his leg or foot was injured, and the original shoes could not be worn, so he found someone to customize plus-size shoes, and seeing that he lives as before, I am afraid that he has become accustomed to this way of wearing, and this person has been here for at least more than 40 days!"

Qiao Jing nodded in agreement, but Su Yang stood up and looked at the two.

"No, there are a few places in your analysis, I don't understand, first, why is he a man and not a woman?"

Jiang Xu and Qiao Jing glanced at each other, and Jiang Xu said.

"This is a preliminary speculation, because if it is a woman, there should be other things in this garbage, which can allow us to accurately judge his gender, such as if a woman has just arrived here, she should at least have some jewelry, cosmetics and skin care products, or ......"

Jiang Xu paused.

"Look at this garbage, this person has been here for a long time, and there are always some special feminine products, such as sanitary napkins or something, of course, it is not excluded that he threw them elsewhere! ”

Su Yang scratched his head in embarrassment and continued.

"Then I don't understand, even if you come out to survive in the wild, you don't have to torture yourself so much, you live here for so long, and you look at this!"

Su Yang squatted on the ground just now and divided the garbage into categories, among which bento drinks and some snack bags accounted for a large part.

"Those who can eat bento boxes and drink milk here are no longer surviving in the wild! Besides, this is not a deep mountain and old forest, and it is estimated that there are no birds and beasts here, so why stay here and not leave?"

Jiang Xu lowered his head and fell into deep thought, but Qiao Jing didn't care much.

After a while, Jiang Xu raised his head, and a smile rose on the corner of his mouth.

"It's also possible that it's not that he doesn't want to go, it's that he can't!"

Su Yang immediately shook his head, and then pointed to the garbage on the ground.

"Bento boxes and milk can get in, why can't people go out?"

Jiang Xu walked over, looked at the snack bags on the ground, and narrowed his eyes.

"It's not the subjective factor that prevents him from leaving, it's the ...... Objective factors, such as ......"

Qiao Jing raised his head and immediately connected.

"Like, there's something outside for him to keep from going out, or for him to feel safer staying here!"

Su Yang nodded, and then his eyes widened in sudden realization.

"Someone out there is trying to hurt him! Or, someone is looking for him, and he doesn't want that person to find him, so he doesn't go out!"

Jiang Xu and Qiao Jing both nodded, and suddenly there was a slight sound of branches swinging at the mouth of the cave, and the three of them were startled, Jiang Xu quickly turned around, made Su Yang's sorted garbage into a pile again, and then took the two of them to run behind a rock in the cave and hid.

"Shh......h Don't talk from now on!"

The three of them stared at the direction of the entrance of the cave, and saw a man dressed in a black coarse cloth coat and a hat walking into the cave.
