Hearing Yuan Dou's words, Lian Yan and Ye Xi began to think. Yuan Dou was very happy to see this, finally he didn't have to work hard alone, and it felt good to have someone to help. But first, Yuan Dou wants to see the environment at night, and after seeing it, it's not too late to decrypt it. Or it would be better to look at riddles and think about them.

Yuan Dou smiled and said, "Don't worry, let's take a look at the surrounding environment first." ”

"Hmm," Lian Yan and Ye Xi nodded.

Tonight, Yuan Dou specially prepared a flashlight, the purpose of which was to see the cave behind the beach. There are all holes in it, which makes Yuan Dou very interested. But first, Mototo wanted to see the beach. So, Yuan Dou took Lian Yan and Ye Xi and walked along the beach on the shore. All three of them were silent along the way, as if they were all thinking seriously.

After walking a lap, Yuan Dou stopped. Seeing this, Lian Yan and Ye Xi also stopped. Yuan Dou turned around and asked, "Did you find anything?" ”

Lian Yan and Ye Xi shook their heads. Yuan Dou didn't have much hope, and he himself felt the same as during the day, and there was no difference. However, walking on the beach here, Yuandou felt a little different when he first came here. What the specific difference is, Yuan Dou can't remember for a while.

Lian Yan and Ye Xi frowned and pondered when they saw Yuan Dou finish asking, and couldn't help but glance at each other. After a long time, seeing that Yuan Dou was still thinking, Lian Yan broke his calm and asked, "Yuan Dou, did you think of something?" Say it, let's think about it together, maybe we will think of it. ”

Yuan Dou raised his head and said to Lian Yan, "Do you feel that the beach here is different from outside?" ”

Lian Yan tilted her head, thought for a while, and said, "Except for the different colors, there doesn't seem to be anything different." ”

"Ye Xi, what about you, how do you feel? Or come to mind? Yuan Dou asked.

As he spoke, Ye Xi squatted down, grabbed a handful of sand and put it in the palm of his hand, looked at it for a while, and said, "The sand here seems to be finer than the outside, I don't know if this counts." ”

"I'll see." Yuan Dou said.

Ye Xi hurriedly put the white sand in his hand in front of Yuan Dou, and Yuan Dou took a flashlight to shine the sand on Ye Xi's hand more clearly. After a while, Yuan Dou raised his head and said to the two: "The sand is indeed finer than the outside, and I feel that the sand here is not only smaller than the yellow sand outside, but also has different compositions. ”

The two were puzzled, and Yuan Dou explained: "You take a closer look at this grain of sand. As he spoke, Yuan Dou kept shaking the flashlight in his hand.

Hearing this, the two got close to each other and observed. "What's going on, this sand is reflecting? It's not round, but it doesn't feel much different. Lian Yan said and pinched a small pinch of sand and rubbed it on her fingertips.

"Of course, you can't feel the difference between such tiny particles." Yuan Dou said.

"It's true that the shape is not round, and I can't see what shape it is, but I feel that it should be a regular polyhedron like a crystal." Mototo's eyes were strengthened so that he could barely see the shape. However, under the light of the flashlight, some of them also reflect the light, so it can be seen that the section must be very neat.

"But what's the use of knowing the difference?" Ye Xi asked.

At this time, Lian Yan replied with a smile: "You are stupid, the shape of this sand is different from ordinary sand, which is enough to show that the sand here is not formed by rock weathering, and may not even be naturally formed." ”

"And then?" Ye Xi asked.

Lian Yan approached Ye Xi when she heard this, and then said solemnly: "There may really have been a dragon here, and this sand may really be made from the corpse of the dragon king." ”

Ye Xi looked at the sand in his hand, as if a mythical creature suddenly appeared in front of him, closed his eyes and thought a little, and suddenly felt a tingling in his scalp. Ye Xi hurriedly threw away the sand in his hand.

Yuan Dou didn't think about it in the first place, but he just felt that the sand further proved that there was something wrong here, and they were probably in the right place. However, Lian Yan's unbridled associative ability suddenly made Yuan Dou feel extremely frightened to think carefully. Yuan Dou suddenly couldn't help but shudder.

The scene suddenly quieted down, coupled with the heavy night and the bright moonlight, people couldn't help but feel a chill.

Probably only
