Outside the valley, except for the big locust tree, there are no lights in other places. It depends on the stars in the sky to illuminate the road, but it's much better than the lights in big cities. For the first time, Chu zhe felt that this kind of environment was really good, and it was very suitable for the elderly.

Yao Wang takes Chu Zhe to visit and introduce him. "Look! Everything in the pond here is planted by your mother. "

Chu zhe looks at the pond by the light of his mobile phone. When the starlight came down, the water on the pond was twinkling with stars, and you could still see the little fish swimming in it.

This pond is different from the one I saw when I came in. Yao Wang said that the pond was for ornamental use. In this pond, Chu Wenni not only planted some lotus roots, but also cultivated some crayfish or snails.

"Your mother is good at cooking. So I often think of some good things for the people in our valley. " Yao Wang is very happy when he talks about the past.

Yao Wang and Chu zhe walked around the pond to a pavilion and pointed to the opposite, "look here, there used to be a cave here. Your mother used to practice calligraphy and martial arts. "

"People here used to pay great attention to calligraphy. As the saying goes, a person's character depends on his handwriting. A person with good handwriting will leave a better impression on people."

"Your mother loved to write calligraphy since she was a child. Of course, sometimes your grandfather would teach her to fight boxing for self-defense. Your mother doesn't like noise very much, so she has a place here. She stays here for a few hours almost every day. "

Although Chu Wenni is not Chu Zhe's biological mother, his mother from childhood to adulthood is Chu Wenni, so Chu Zhe is more interested in hearing about Chu Wenni.

"Yao Wang, why don't you take me to the other side of the cave." Chu zhe looked at the dimly shaped place on the opposite side and couldn't help but want to have a look.

"What are you doing over there? It's getting dark. There's no light to go there. It's better to go in the daytime. " Yao Wang doesn't want to go there in the dark.

"But I want to see it. What's more, we have mobile phones. Just turn on the flashlight. "

But Chu zhe couldn't help it. The king of medicine had no choice but to lead him forward, "OK, let's go. I'll show you. You must follow me

Chu zhe followed the king of medicine to cross a stone bridge on the pond and arrived at the place where the cave was. As soon as Chu zhe came over, he found that there were some shining green lights on the cave.

"Why is there a little green light here?" Chu zhe pointed to the green light on the wall and said in surprise.

After hearing this, the king of medicine turned his head and looked at the direction Chu zhe pointed to. He widened his eyes. "This, how can there be phosphor?"

What does the discovery of phosphor on the wall of this cave mean? Of course, it means someone has been here. The king of medicine is confused. Has anyone been here?

"Yao Wang, has anyone been here?" Chu zhe also raised his own question, "but why do people come here?"

"I don't know." In fact, Yao Wang is not sure if someone came here not long ago. "In principle, if it was the phosphor left over more than 20 years ago, it would have dissipated."

"But now these phosphors can be seen more or less, which means that the time for the phosphors to fall is not long. That means that this phosphor was sprinkled here not long ago, so this person must have come to the valley before. "

"Maybe it's the man who takes care of the medicine field. If he's not a savage in the back mountain, he's probably an outsider. If it's really an outsider, it's amazing. Come on, let's go and find your grandfather now. "

Yao Wang thinks this is a big deal. He must inform Chu Yinglong immediately, otherwise, the consequences may be unimaginable.

At this time, Chu Yinglong did not stay with them, but stayed alone under the big locust tree, thinking of his daughter. Chu zhe trotted back, running and shouting, "grandfather, come and see!"

"What's the matter? Big night, the light is not good, run so fast why, careful fall Chu Yinglong smiles and looks at Chu zhe without moving his eyes. He is afraid that if he is not careful, Chu zhe will fall down.

"Grandfather, come with us quickly. We found something suspicious in the cave."

What Chu zhe said really made Chu Yinglong nervous, "what's the matter? What did you find? Is something wrong? "

"Come here, grandfather. Big deal. We found traces of phosphor in the cave

"What?" Chu became nervous. Asked hastily.

"I said, we found traces of phosphor. Yao Wang Gang said that if it had been left 20 years ago, the phosphor would have dissipated. But now we can see the shining green light. That means someone must have been here. "

"Come on, show me." Chu Yinglong is worried. As soon as he hears about the phosphor, he can't wait to go and have a look at it.

Before Chu zhe had time to hold him, he didn't even use his crutches and walked forward quickly."Grandfather, slow down. Wait for me. I'll help you Chu zhe followed quickly, fearing that Chu Yinglong would fall into the pond.

But Chu Yinglong walked more steadily than he did. In the blink of an eye, Chu Yinglong crossed the stone bridge. As he walked, he said, "what's going on?"

Chu Yinglong gradually close to the cave, vaguely see a little bit of green light flashing, Chu Yinglong is sure that this green light is phosphor. "Who on earth made this phosphor here?"

No one could answer him, "why don't we go inside and have a look."

Yao Wang didn't believe that the phosphor was only on the outside, and there must be phosphor in it, so he suggested, "since you can see phosphor here, there must be phosphor not far away. Why don't we go to the cave and have a look. "

"It's reasonable to say that since we left 20 years ago, no one should have been here in this cave. There's no reason for phosphor to remain here, so I suspect there's something strange here. Why don't we go in and find out?"

Yao Wang's words haven't been finished yet. Chu Yinglong has already stepped inside. As the king of Medicine said, there was still phosphor in it.

In the face of the residual phosphor on the cave wall, Chu Yinglong and Yaowang are extremely curious and full of doubts. "What's going on? Phosphor. It's extended here. "
