"I bought all the things Jia Lei back!" Dasha came back with a tricycle of things, and he also brought back a box of ice cream.

Jia Lei handed half of the ice cream to Wei Cheng and asked them to share it, and then gave one to the old lady and her granddaughter, and then took a mung bean ice cream and ate it.

"Can a friend sell me an ice cream? I'll pay double the price." A man standing in front of Jia Lei said.

"Ten times!" Jia Lei said without raising his head.

"This is too expensive, isn't it? How dare you sell something for three cents for three yuan! You are speculative, and you would have been sentenced to prison ten years ago. The man said angrily.

"Do you want to buy it, anyway, I'll just buy these few ice creams! Jia Lei said nonchalantly, hearing the people around him talking about it.

"The kid is right, if you don't buy it, get out of the way!" I'll get two sticks of cream ice cream, and I'll give you ten yuan!" shouted a nearby Hong Kong resident.

"Dasha brought the ice cream to the people. Jia Lei said that Dasha obediently took two ice creams and sent them over in exchange for ten yuan.

"Is there really anyone buying it here? Professor Yu only raised the price by two cents when he was selling ice cream in front of him, and everyone was too expensive to buy it. Dasha said in disbelief.

"That's because he's gone up too little! If only he had raised the price tenfold like me, and there's still someone over there who wants to buy ice cream, so you can send it over." Jia Lei pointed to another group of people with cash in sacks.

There are only more than 20 ice creams left in Dasha, and they have been sold out in less than three minutes, and people who were reluctant to buy ice cream at the beginning now regret it, but fortunately, there are still a lot of soda in Dasha, Jia Lei asked Dasha to call Yu Tao over after selling things and going back.

"Dasha, you remember, no matter what you sell later, you have to add a zero to the price of the store and increase it tenfold before selling! Including melon seeds!" Jia Lei specially admonished Dasha.

"Children are a piece of business material, and they will become great things in the future!" said the first Hong Kong man to buy ice cream, and the sun was shining brightly on the two large gold rings on his hands.

"Everything is sold at a tenfold price increase, and you are too black-hearted! Isn't such a high price a trick!" Yu Tao said angrily.

"You're a good person! You don't raise the price! But is anyone buying your stuff? It's not like I was scolded as a profiteer. Jia Lei asked.

"I just charged 2 cents for the fare, but these people are still too expensive! The price they give is the same as the price I buy from the store, and I can't be asked to sell at a loss after running so far and making great efforts!" Yu Tao said angrily.

"Then will anyone buy it after I raise the price tenfold?" Jia Lei asked.

"Yes, you are the only thing in the neighborhood, how can no one buy it!" Professor Yu said angrily.

"You are a student of economics, the concept of the market should be clearer than me, there will be a market when there is demand! And my transaction is absolutely open and free trading, adhering to the principle of mutual consent is not forcing others to buy. To put it bluntly, it's a matter of what you want me to do!" Jia Lei said.

"Don't forget, there are ......regulations for the overall material situation," Professor Yu said.

"Stop!" Jia Lei immediately interrupted him.

"The price bureau is in charge of the national economy and the people's livelihood, and my little matter cannot attract its attention at all, do you think this little transaction volume can cause fluctuations in market prices? The key is that I am a hammer deal, and I will stop doing it when the price bureau comes to arrest people tomorrow. Jia Lei crossed Erlang's legs and said triumphantly.

"You...... I'm going ......to do it, whoever you love for this black money will make it! I'm going to break up the gang. Professor Yu Tao said angrily.

"Okay! You can do whatever you want, don't be angry! It's so hot, if you get a heat stroke, you'll be in trouble. Jia Lei hurriedly said.

Professor Yu is also in his forties, and it will be bad if he gets angry, so Professor Yu Tao hides in the shade of the green belt alone and sulks.

**(Half an hour later)

Jia Lei looked at Professor Yu who was still angry and couldn't help but feel a little weak, and he decided that there were a lot of adults who would give in to the old man first.

"Professor Yu, come here, I want to tell you. Jia Lei shouted at the green belt, and Professor Yu glanced at him and ignored him.

"Aren't you angry at me for making black money, it's a big deal that I'll return the money to them!" Jia Lei shouted, Yu Tao glanced at him and walked over slowly.

"Really, how are you going to pay it back?" asked Professor Yu.

"I can't pay anything else, didn't I sell a lot of small Mazha small benches, and I have now decided to use five yuan to recycle the sold small Mazha small benches. As for the other things I ate and drank, I really can't recycle them, so I can't let people spit out what they eat. What do you think of this idea?" asked Jia Lei.

"That's a good idea, but are you really so conscientious? I don't believe it a little!" Yu Tao said suspiciously, he felt that Jia Lei was a Pixiu who couldn't get in or out.

"If you don't believe me, you can do it yourself! I'll give you the money, you can believe it. Jia Lei said, and Professor Yu nodded with satisfaction.

"Do you know how to recycle the pony bench?" asked Jia Lei.

"This ...... I can go shout and see who's selling. Yu Tao said.

"How much trouble is that? This line is so long, how long will it take you to walk back and forth to get back all the bench ponies I sold. I'll point you in a good place to make sure you can recycle easily!" Jia Lei said.

"Where is it?" asked Yu Tao curiously.

"You sit down at the door of the securities company and put up a sign at the recycling office, which says that the small Mazha bench will be recycled for five yuan. People who come out of the securities company will definitely not need a small bench, and most people will sell it. And it's more convenient for you to investigate the situation at the door of the securities company, isn't it? I think the survey data is better to be comprehensive, and the data in the securities company is also very important. Jia Lei said, Professor Yu nodded and agreed.

Jia Lei hurriedly handed him the prepared signboard and money, and Professor Yu's eyes widened as soon as he glanced at it.

"What's the matter with the recovery of the allotment shares? You actually raised the price by one yuan per share and let me help you collect the allotment shares? Do you want to trick people again?" Professor Yu asked angrily.

"Where do I have a cheater, I'm helping others! There are many people who don't have the money to allotment shares or don't want to allotment shares, how wasteful are those allotment shares? I'm using waste to help them turn waste into treasure and sell waste products to make money!" Jia Lei pretended to be a good person and said, Professor Yu really didn't know what to say.

After all, what Jia Lei said is right! This is indeed a beautiful thing that kills two birds with one stone!

＊＊＊＊

"How's Dasha's business?" asked Jia Lei.

"It's much better than before, in the past, a small bench for ten yuan was too expensive for everyone, and not many people bought it! Since everyone knew that we recycled the small bench at the entrance of the securities company for five yuan each, there were a lot of people who bought a small bench and a small maza. I've sold out of several shops around the area, and I'm wondering if I'll have to go further afield to get my goods. Dasha said.

"What's on it, what's on it!, Professor Yu, don't you have so many small benches, why do you have to buy them elsewhere, and when you're out of stock, just go and get them!" Jia Lei said, counting the money.

"Isn't that what Professor Yu recovered?" Dasha asked.

"That's what I paid for to recycle, even if I paid for it, the thing is mine! The bench can be reused, and there will never be a guest who dislikes it! By the way, I forgot to tell Professor Yu that if the recycled small bench is too dirty and too broken, it will be recycled at a discount. You can help me tell him when you go over to get something later!" Jia Lei suddenly remembered this.

"Jia Lei, is this what my mother said kill two birds with one stone?" Dasha asked.

"Of course not!" Jia Lei denied.

"I'm killing three birds with one stone!" Jia Lei stuffed the money into his bag and said proudly.

After queuing for two days and one night, Jia Lei finally exchanged a sack of money and dividends for Shenzhen Development stocks, and he stood in the securities company and looked at the newly arrived stocks excited-to death!

"I'm going to die! It's itching to death! Why are the mosquitoes in this Pengcheng City so powerful?" Jia Lei scratched the mosquito bag on his body vigorously and said, he has been unrecognizable after the queue in the past two days, and there are three or four mosquito bags on his face!

"Oh, don't you know, now the people who come to Pengcheng are the elites of the whole country, even the mosquitoes are elites, and the rats in Pengcheng are bigger than other places!" Li Yaoyao said, Jia Lei was speechless when he heard it!
