"Gambling stones?" Zhao Feng frowned, he naturally knew that gambling stones, although he had never seen them with his own eyes, he had always heard them, and most of them were rumors of getting rich overnight and losing money overnight.

"That's right! Didn't Zhou Da and I read those Long Aotian's online novels when we were in high school? In it, the protagonists are all with heavenly eyes, and they casually kill in the gambling stone field, at that time, I discussed with Zhou Da: Is it possible to see through science and technology through the skin of the stone, and directly glimpse the jade inside the stone? Later, we gradually discussed the concept prototype of a 'gambling stone machine', if this kind of machine can be developed, then the gambling stone is completely a big deal with no loss and amazing profits!" Cai Jie explained excitedly, obviously not realizing how many greedy people would covet his idea once it was realized.

"So, you succeeded?" Zhao Feng frowned.

"Hehe, that's of course! Two days ago, I went to the gambling stone field with Zhou Da to test the performance of the first gambling stone machine, and the results were satisfactory! We only spent less than 2,000 yuan to drive three pieces of jade, and made a net profit of more than 68,000 yuan! Brother, to be honest with you, from that night onwards, you were the only virgin left among the three! I now finally believe that you can really do whatever you want if you have money! Look! This is the gambling stone machine we made! Cai Jie smiled obscenely, and then handed a pen to Zhao Feng, Zhou Da on the side frowned slightly when he saw this, but quickly returned to normal.

Zhao Feng played with the iron ballpoint pen in his hand, except for being a little heavy, there was nothing special about it.

"You press the cap!" Cai Jie reminded.

Click!

A light red light was projected, and the light was inconspicuous, and if it was an afterglow, it was estimated that it would not be noticeable.

"This light can pass through the stone layer of one centimeter on the surface of the wool, and then see the color of the jade under the stone layer, although it is only one centimeter, but as long as you choose more, you can always pick up the leak! In the past two days, I have made up some knowledge about jade, and today we three have joined forces to make a lot of money!" Cai Jie rubbed his hands, looking like he wanted to show off his skills.

"How much do you think the gambling stone machine can make you?" Zhao Feng pondered for a moment, then asked rhetorically.

"Well...... Zhou Da and I simply calculated, to say the least, it is tens of millions, if you are lucky, you will encounter good materials, hundreds of millions of dollars is not impossible, however, our gambling stone machine can currently see through the depth is limited, so the accuracy will fluctuate depending on the specific situation of the material, if the second debugging can increase the perspective depth by four or five centimeters, then the accuracy and income will be greatly improved!" Cai Jie is full of confidence.

"The value of tens of millions, hundreds of millions is for you, for those merchants who have the source of gambling stones, it is not an exaggeration to say that it is priceless, if the merchants know that this kind of gambling stone machine with unlimited value is in the hands of two high school students, guess what they will do?" Zhao Feng asked in a slightly cold voice, Cai Jie was obviously carried away by the huge interests, otherwise how could he be unaware of such an obvious potential crisis?

"You mean...... Someone will kill people and oversell goods? No, right...... It's not a novel or a movie, we live in reality, and it's illegal to kill someone! Besides, our gambling machine is not omnipotent, it has limitations!" Cai Jie waved his hand and said in an indifferent tone, but the look on his face was obviously wrong.

As for the limitations you mentioned, you as a developer naturally know about them, but for other people, they only see you making money...... While there is no trouble to find the door now, find a suitable price, and sell this machine. Zhao Feng persuaded earnestly, Cai Jie showed a thoughtful look when he heard it, but Zhou Da on the side didn't buy it.

"Ah Feng, you are too worried, in fact, we are also very cautious, there are often buyers at the gambling stone scene with a flashlight to shine, we hold this gambling stone machine, others still think it is a child to play infrared, will not care at all! As long as we don't say it, make a fortune in silence, no one will find out!" Zhou Da didn't care at all, thinking that his secrecy measures were perfect.

Zhao Feng was silent, he could see that Zhou Da was more addicted than Cai Jie, and no matter how much he said at this time, it would only cause the other party's resistance, since he knew that persuasion was useless, why waste his words?

"Ah Feng, let's do it, you go with us today and see our actual operation on the side, maybe it's safer than you think?" Although Cai Jie listened to Zhao Feng's words, he still didn't want to give up easily.

"Okay, where are you going to gamble on stones? I haven't heard of a gambling stone market in Nanshan City. Zhao Feng nodded and agreed, and returned the gambling stone machine to Cai Jie.

"Hehe, you don't know this, there is a black market in the XC area, and there is a gambling stone market inside! There are all kinds of antique calligraphy and paintings, jade and gold utensils! But except for gambling stones, most of the others are bartered transactions, of course, since it is a black market, it is naturally mostly fakes, but we don't touch those, so we go straight to the gambling stones!" Cai Jie said and took the lead out of the classroom.

Cai Jie originally had a scooter, he carried Zhou Da, Zhao Feng followed, and the three of them went straight to the XC area.

At 9:07, Zhao Feng and the three of them came to the XC area and came to Laomian Street, and stopped in front of the left alley at the end of the north.

"This is the black market?" Zhao Feng was a little surprised, there were two rows of stalls on the left and right in front of him, many buyers stopped and stopped, and everywhere they could hear the shouts of buyers and sellers bargaining with each other, this was almost a small night market on the street, but it was daytime now.

"That's right! This should be regarded as a night market that is open all day, there are sellers here 24 hours a day, all sales must be outside the house, and every once in a while there will be a police uncle to check the post, the black market is just an exaggerated name, do you think that there is really a black market is as mysterious as in the novel? The policemen in the gambling stone novel are all Miyamoto super soldiers who have been maliciously weakened countless times, and they can't be taken seriously! Go! Brother Jie will show you the world of gambling stones today!" Cai Jie explained, and then led the reunion with high spirits, and finally stopped in front of a stall full of large and small stones.

"The two little brothers are here again, welcome, welcome, take a pick, see which one you like, I'll give you a discount!" The stall owner is a middle-aged man in his forties and fifties, bald and edging, with a big nose and a sharp mouth, like the legendary monster kappa of RB.

"Uncle, the two pieces I picked up here last time didn't work at all, I went home and wiped them for a long time, but there was no wool, I broke them in a fit of anger, and they were all stiff stones! Nine hundred and ninety-eight yuan! I lost to death!" Cai Jie complained with dissatisfaction.

In fact, those two pieces of wool produced a piece of mahjong-sized glutinous rice jade and a fingernail-sized thick bean seed, which were sold for 50,000 and 4,000 respectively.

"Little brother, this can't be helped, my wool is also purchased from the wholesale market, gambling stones are like this! Gambling and losing is the norm, and winning gambling is the ability! If it is really so easy to make money, I will not come here to sell wool to make the difference." The stall owner waved his hand, looking like it was none of my business.

"Alas, uncle, I don't blame you, it's just that the money was spent unjustly, but I just look at the material on your stall, this may be my last gambling stone, I have brought all the New Year's money I have saved in the past eighteen years, and I will believe you again!" Cai Jie showed the fanatical expression of a gambler, and Zhao Feng on the side couldn't help but want to applaud.

This acting skills, it's no problem to give a little golden man base!

The stall owner looked left and right, beckoned to Cai Jie and the three of them, and motioned for the three of them to squat.

"Little brother, I don't think it's easy for you, so let's do it, I have a piece of window material for pressing the box here, which is the material from the mouth of Damakanchang, the meat quality is average, but the potential is great! Are you interested in taking a look?" The stall owner patted the wooden box sitting under him mysteriously.

"Take it out and take a look!" Zhou Da was the first to show an interested expression when he heard this.

The stall owner smiled, got up and opened the box, took out an oval stone the size of a basketball, wrapped in red cloth, lightly placed it on the cushion on the side, and lifted the red cloth under the expectant eyes of Cai Jie and Zhou Da.

The leather is yellowish-red, the surface is cleaned very clean, and there is an oval window on the front and back of each end, and all four windows are evenly reddish.

"I want this piece of material!"

At this time, there was a voice behind Zhao Feng and the three of them that could not be refused.
