All four of them were terrified - if they had run a little slower, the consequences would have been dire. But because the professor is the oldest, so compared to the other three, the reaction is a little slower, so he ran at the end, and was rolled down the stone, hit the ankle, just now because of nervousness, did not feel pain, and when the danger passed, the spirit relaxed, then I felt the pain of his feet burning, when he lifted the hem of his trousers, and looked carefully, he found that his foot and neck had been swollen, and a large bruise, a little hard, it was extremely sore.

Another student, also a wolf, lost a shoe. Originally, a pair of suitable shoes was the most important thing for the wild adventure, he also wore a pair of sneakers with very heels, but because there were indeed too many mountain roads in the past few days, so there were several bubbles on the feet, and last night before going to bed, he just took the medicine, and it was not completely good, so in order to make his feet comfortable, he did not tie the shoelaces too tightly, and he did not expect to encounter such sudden danger. So in the process of escaping in a hurry, the shoe was thrown off, but fortunately, it was not buried by the falling stones, he hurriedly jumped over on one leg, and picked it up and put it on, there were all kinds of sharp gravel in the valley, and there were many thorny plants, and it was not possible to leave the shoes.

Everyone was still in shock, and after a long time, they discussed whether to continue to explore the cave, but seeing that the professor's feet were getting more swollen and higher, and the teeth were grinning in pain when he moved a little, even if it was difficult to move an inch, how could he continue to enter the cave? But this expedition can be without anyone, but not without the professor, but the problem is that with such a serious foot injury, even if the professor wants to enter the hole, he is more than willing but not enough.

The four of them, especially the professor, felt that it was a pity to go back like this, but they really had no choice but to do so.

When they finally climbed out of the valley, the four of them were exhausted, so they found a boulder and lay down on it for about forty minutes before deciding to continue on their way. Because they didn't bring tents, they wanted to rush back to the county town down the mountain before nightfall. For the professor, in addition to being tired, there is also the pain in his ankle every time he moves a little.

He wished that the family at the foot of the mountain, as mentioned in the Jewish book, was still there, and that if the descendants of that family still lived at the foot of the mountain, they would be able to go and stay there. If that's the case, maybe we'll be able to find out more about the mountain.

But with such a large mountain, who knows in which direction the family, even if they still live there, will live at the foot of the mountain? The professor suddenly felt that his idea was ridiculous: the time when the Jews had lived for at least 200 years has been now, and in these 200 years, there have been many wars and chaos, and the world has changed, and the family that lived at the foot of the mountain has moved somewhere, and the possibility of still living here is almost small.

The sky is getting darker and darker, and the four of them hurried down the mountain, and when the mountain road is good, the two students take turns carrying the professor, but some sections of the road are really rugged and dangerous, so they can only put down the professor, and the three of them let the professor go by themselves, and every time they get to this time, the pain in the ankle comes from the ankle
