The two-day college entrance examination is fleeting.

Even if it is a student with particularly good grades like Yang Tian, he can't help but breathe a deep sigh of relief. From the first grade of primary school to now, more than ten years, just for these two days of college entrance examination, it is really not easy!

"Mom, I'm out!", on the first day after the college entrance examination, Yang Tian got up early, and after eating breakfast, he said to his mother Shen Xinlan. As for her sister Yang Shan, who is still sleeping in the bed, Zhengxiang.

"Come back early, there are 20 yuan here, you take it, and go online with your classmates!", the mother Shen Xinlan looked at her son happily, felt in her pockets for a long time, and then took out a crumpled 20 yuan, and stuffed it into Yang Tian's hand.

"Mom, no, I'll just go out and come back at noon! Yang Tian hurriedly excused himself. He stuffed the money back into his mother, and hurried out.

"Alas, Xiaotian, go slower, be careful of panting", Shen Xinlan saw Yang Tian walking in a hurry, and shouted anxiously.

Yang Tian waved his hand relaxedly, and disappeared in front of Shen Xinlan's eyes after a while.

Shen Xinlan clenched the crumpled 20 yuan in her hand, but her eyes suddenly filled with tears.

"If your child's weight is no longer controlled, his heart will not be able to bear the weight, and he will be paralyzed and may be confined to bed for the rest of his life," said an old expert from a large hospital three months ago to Shen Xinlan and Yang Jiaguo.

"Whew!", Yang Tian gasped a few times, feeling his chest tightened in panic, but his steps still kept moving forward. His gaze is very firm, just to take advantage of the two months of summer vacation to adjust his body a little.

With his tattered body, he still wants to make money? Yang Tian sometimes wants to use a knife to scrape off the fat on his body, it is too painful.

After persisting for more than an hour, Yang Tian finally couldn't hold on, and suddenly sat down on the ground, his face pale, and he gasped for breath.

There was a frolicking sound in the distance, and Yang Tian looked up. I unknowingly came to the edge of the ocean in County A.

As a typical land of fish and rice, county A has a lot of water as a major feature, and almost all traces can be found in county A, regardless of rivers, lakes and seas.

At this time, Yang Tian's eyes lit up slightly, but what he was thinking about was the treasures in the ocean.

Yang Tian has good academic performance, reads a lot of books and miscellaneous, and knows that there are many treasures in the ocean. For example, someone accidentally saw a conch on the beach and sold it for a sky-high price of 150,000 yuan. There are also the well-known sea mussel pearls, precious seafood.

Yang Tian struggled to stand up and slowly walked towards the beach. The area of this sea is not large, but it is connected to the sea, and people still feel their own insignificance when they stand in it.

This is a piece of the open sea, and almost all the children who play here are children, and when they saw Yang Tian, a "big monster", coming over, they screamed and ran on the beach.

Yang Tian walked slowly on the beach, turning over the small rocks at the edge of the ocean from time to time, hoping to find something valuable, but there was nothing else except the occasional small crab.

Yang Tian also knew that he was just wishful thinking, if he could make a fortune in this way, anyone would be able to find a treasure here.

After groping on the beach for more than two hours, to no avail, Yang Tian could only rest on a rock by the sea. Looking at the endless ocean of waves, Yang Tian's heavy heart also became broader.

"Shhhhh

Yang Tian was about to stand up, when he suddenly felt a tingling pain from the place where his left palm was forced, and hurriedly looked at the palm, but found that his left palm accidentally pressed on a sharp pebble, and the palm of his hand was punctured.

Yang Tian shook his head with a wry smile, and tried to stand up, but suddenly a burst of dizziness came, the whole person was unstable, and he fell down again, and felt a tingling pain in his left palm, and he was actually stung by the sharp pebble again.

"Damn!", Yang Tian couldn't help but curse in a low voice, picked up the sharp pebble in his hand and threw it hard, throwing it into the sea.

"En, isn't it right?", Yang Tian suddenly felt an itch in his eyes, as if he saw that something seemed to exist in the sharp pebble, calling him deeply, and he had a reluctant feeling in his heart. It seems that if you don't get it, you'll regret it or something.

"Wow!", Yang Tian's fat body jumped directly into the sea. He has always believed in his instincts, just like during the exam, sometimes he can't do multiple-choice questions, and the probability of being right can even exceed half of the questions.

The sea water of ten meters nearby is very shallow, no more than two meters at most, Yang Tian soaked in the sea water, groped for a long time, and put the Buddha in the power of the destined general, the sharp pebble was really found by him.

"Hey, hey. Yang Tian smiled stupidly, put the stone into his pocket, and then walked slowly towards his home.

In the summer sun, when Yang Tian walked home, his clothes were almost dry, but after soaking in seawater, there was salt analysis, and he felt uncomfortable, so he took a hot bath.

"Mom, where is Shanshan?", Yang Tian took a bath, didn't find his sister, and asked his mother Shen Xinlan.

Yang Tian actually loves his sister very much, but Shanshan is young and ignorant, and always dislikes her big fat brother, causing her to always be ridiculed by her friends, and she is usually not called Brother Yang Tian.

"That girl went to Xiao Jia's house to play," Shen Xinlan said with a smile.

"Oh, then I'll read the book", Yang Tian nodded with a smile and said to his mother.

Back in his room, Yang Tian took out the pebble from his pocket.

The pebble is roughly conical in shape, with a length of about 4 cm and a base of 3 cm, and from the outside, it is no different from ordinary pebbles.

Yang Tian observed for a long time, thought about it, took out a knife from his schoolbag, and slowly cut the pebble.

I don't know if it's because the pebble is too hard, the knife was carved on it for a long time, leaving only a faint trace.

Yang Tian found a hammer and a steel cone from his home and leveraged the stones.

Small stones can only be said to be a little harder than ordinary stones, and when they are pried by hammers and steel cones, they keep falling fragments, and their size is getting smaller and smaller.

Yang Tian's eyes suddenly lit up, he seemed to see a small stone wrapped in something, and he took a basin to bring a large half basin of water, and cleaned it while removing the stone fragments.

In the end, what appeared in front of Yang Tian's eyes was a small bead with a diameter of only 2 centimeters, which was blue and red, mixed together, just like the kind of marbles that ordinary children play, but it looked a little ugly.

What is this? Yang Tian looked down for a long time, without a clue.
