The string of ornaments was so swaying that Zheng Si was dizzy, and he couldn't see it clearly, so Zheng Si reached out and took a closer look at the string of ornaments, it was indeed very similar to the bag of things he had seen.

When Zheng Si was looking at the string of ornaments, Jiao Wei came running, they didn't have classes in three or four classes this morning, he just stayed in the library, and he planned to go to the restaurant when he saw the time, to avoid the rush hour after class later, during this time, every time he ran to this road, he would look at both sides of the road, especially those tall trees that are suitable for cats to sleep on their stomachs and those wooden chairs on the side of the stone road, Zheng Si is very picky to sleep. Sure enough, without much effort, he saw a black cat lying on a chair.

"Black charcoal!"

I didn't know the man and the woman, Jiao Wei just called Zheng Si's name and waited next to him, seeing the man and the woman looking over, Jiao Wei nodded at them with a smile, and didn't say much, he usually didn't talk much.

Seeing Jiao Wei, although Zheng Si was a little curious about the identities of these two people, eating was the most important thing at the moment, and besides, these two people might not really have anything to do with the bag of things, so Zheng Si didn't waste much time, jumped off the wooden chair, and trotted towards the direction of the school gate with Jiao Wei.

After eating at Jiao Wei's restaurant at noon, Zheng Si found a place to rest. Jiao's father also called the restaurant to inquire, and he didn't say anything when Zheng sighed here, and Jiao's father didn't come here for a few teachers to eat in the cafeteria at noon.

Lying on a tall plane tree and sleeping, Zheng Si planned to go out and hang around. I haven't been out of school for the past few days, so I went to Xiaoyuzi's junior high school to take a look, and then continued to walk forward until I heard the familiar erhu sound and saw the familiar flyover.

That old blind man is here today! It's a rarity.

In the past year, the old blind man has come to the overpass a lot less often, and sometimes Zheng Si can't touch it when he walks this way, and he will only see it when he runs to the alley where the old blind man lives.

Zheng Si was walking that way, and he found that there was a low-key black private car not far from him in front of him leaning to the side and slowly stopping, and the two people who got out of the car were the same man and woman he had seen at noon.

Zheng Si looked at them. The two people who got out of the car over there also saw Zheng sigh.

"Black cat again? Is it popular to have black cats here? The woman said.

"It's the one I saw at noon." The man was a little surprised. Then he smiled, not paying much attention to it. Different cats look at people differently, and the black cat's eyes are very special, but. Even if it's the same cat. It's not a big deal to meet here.

"It doesn't have a cat tag." The woman's way. It's not that I doubt the opinion of those around me. She just voiced her doubts. Generally speaking, pet cats are hung with cat cards when they are outside, although there are not many rigid requirements in this regard in China. But since it was hung in the morning, why did you take it off in the afternoon? Of course, this was only her temporary doubt, and she soon stopped paying attention to the problem of hanging cat cards.

The man and woman looked away from Zheng Si, and no longer continued to pay attention to Zheng Si, chatting in a whisper and walking forward.

Zheng Si was only surprised when he saw these two people, and he didn't bother to care about anything else, so he walked his own way and went all the way to the overpass. Then, Zheng Si found that the man and the woman had walked up the steps of the overpass like him, and after going up, the two of them were standing against the railing in an empty space on the side, and the woman opened the parasol, and the sun was not so mild this season. The man looked at the middle of the overpass, and his eyes stopped at the blind old man who was playing the erhu.

"Thomas, that old man is the one you're looking for?" The woman asked.

"Hmm."

The woman was about to ask something more, when she suddenly said, "Hey, the black cat has passed!" ”

Both of them were surprised, they had seen a cat with fat guts, but they had never seen such a fat cat, and people on the overpass could walk calmly on it, as if they had never seen a cat with people in the air around them.

In the eyes of the two men, the cat walked up to the old man who pulled the erhu, stood beside the box with the money as if no one was around, scooped up the coins, and fished out two of them one after another, and then stood in the shade under the big umbrella and opened his mouth and yawned.

Two: "......"

After a few seconds of silence, the woman said, "Thomas, that old man has a really good temper. ”

The man didn't say anything, but what he thought in his heart was: If the temper was really good, there wouldn't have been so much bloody rain in the secret, and the people who fought hard in real swords and guns, especially those like the one over there, have a temper that can never be described as "good". It's just that the cat is a little too bold, and many people have said before that many animals avoid the old man.

Zheng Si yawned, he just found two game coins in the old man's box, every year in the beginning of the school season in September, there are always some students who think they are smart and throw some game coins into the box, but when they think others are fools and make a fool, others also think that they are simply doing death, but many people disdain to do it. Isn't there a saying that you look at fools on the bridge, and you see fools looking at you around.

When Zheng Si yawned for the second time, the old man finished the song and began to pack his things.

This makes Zheng Si a little strange, the time hasn't come yet, right? The old man has something to do and wants to leave early?

Not only did Zheng Si think so, but several small vendors on the overpass were also muttering: "Why did his old man go back so early today?" Do we also have to close the stall in advance? ”

"Take it, I guess he heard something, for the sake of safety, let's follow suit."

So, behind the old man, some small vendors also began to pack up their things one after another, of course, there are also some vendors who still stay there when they see that the business is good, the old man has not come over most of the year in the past year, don't they also set up stalls?

Zheng Si saw the old man collect his things and leave, and followed behind, he hadn't been to the old man's side for a long time, and he didn't know if Xiao Jiu was there recently. After walking a few steps, Zheng Si found that the man and the woman were also walking not far away. Glance back at them. Zheng Si continued to walk, and after leaving the overpass a certain distance, Zheng Si saw a fruit vendor who was quickly passing from behind, running in a hurry. Looking back at the overpass, the few vendors who stayed in place on the overpass hurriedly packed up something, obviously, there was an inspection in the past, and quickly packed up and slipped away.

Looking at the old man with a gentle pace, Zheng sighed and pouted.

Walk through that shopping street and into the familiar alley. The man and woman behind kept a distance of six or seven meters. Zheng Si was surprised again, these two people know the blind old man?

At the same time as Zheng sighs about the difference, the two people behind are also different, does this cat know the one in front of him?! Isn't this the ordinary cat that ordinary people in that university have?

Look at the reaction of the person who opened the door. Whether it's seeing that man or woman or Zheng sighing. There are no other superfluous expressions.

Sure enough, it's acquaintance!

After entering the house. Zheng Si came to the living room and jumped on a chair to sit down, which was much more natural than the two people behind.

"Uncle Kun. Long time no see. The man bowed slightly to the old man.

Zheng sighed and shook his beard, "Uncle Kun"? Although this title is a word difference, compared to the public version of the title "Kun Ye" that Ye Hao and they shouted, the relationship seems to be much closer.

"It's been seven years, Tom Mo, you kid is coming back now to enter the domestic market?"

The old man's tone also had some rare familiarity, and Zheng sighed couldn't help but look at the guy named Tang Mo again, what is the origin of this person?

Tang Mo smiled slightly, "That's what I mean, it's just that I just came back and ran into a little trouble, and I couldn't figure it out, so I came to you for help." ”

There is no beating around the bush, it is direct enough, and it also has a kind of intimate tone of junior to elder, one shows that this person knows the old man's temper very well, and the other also shows that this person is indeed very familiar with the old man, if it weren't for the fact that these two people really don't look alike, Ye Hao and they also said that the old man has no biological children, Zheng Si will really think in that direction, if there is no blood relationship, it may be the reason for Tang Mo's father.

"Oh?" The old man took a sip of his teacup and didn't say anything superfluous.

Tang Mo took a box handed by the woman next to him and opened it on the table in front of the old man.

There were several loose diamonds of different shapes, each of which was more than five millimeters, and the largest one was nearly a centimeter, Zheng Si didn't know how to evaluate the value of a diamond, just supported his ears to listen to their conversation.

The old man put down the cup, got the box accurately, brushed his fingers over the diamonds, picked one up and touched it, and smiled: "It's good, better than before." Your father will be glad to know you. ”

Zheng sighed and was stunned, listening to this, are those diamonds that look very eye-catching fake?

"Put graphite and some of its auxiliary materials into a special box, stuff the box into a special instrument similar to a pressure cooker, simulate the temperature and pressure of diamond formation below the earth's surface, graphite changes, three days later, take out that box, open it will get a diamond crystal, compared to the naturally formed diamonds that take hundreds of millions of years to make, they only take a few days, much cheaper than the natural digging from the mine, but that was only three years ago." Tang Mo picked one up, looked at the light reflected on it, and his eyes were full of confident smiles, "These are the products of new techniques, the cost has increased slightly, and it only takes a few days, but they are no different from natural diamonds that were naturally formed by high temperature and high pressure more than a billion years ago, and they can still grow." ”

"Congratulations. It looks like the jewelry market is about to start a war again. The old man's tone didn't change much, and the benefits behind it didn't make him very excited, "I remember that when your father put forward that plan, he said that once the technology matures, its impact on the market will be no less than the arrival of the steel age in the 50s of the 19th century and the invention of the transistor in the 40s of the 20th century. ”

Diamonds, not only as gemstone ornaments, but also allow computers to run at speeds that can melt the internal organs of current computers, and electronic, mechanical, and even thermal weapons can infiltrate and bring about reform. Although there is still a long way to go from the ideal and there are still many problems that have not yet been solved, Tom Mo feels that he has taken a big leap forward.

"Until then, I'd like to ask Uncle Kun to help me find a bag of experiments that were stolen by mice." Tommer put down the diamond and said.

Zheng sighed and straightened his ears and turned to that side. (To be continued......)

PS: Unconsciously, it's three hundred chapters, over a million words, and today I look at the evaluation index where there are three diamonds, and the recommended votes are over 450,000, and I squeezed into the top ten in the urban classification monthly ticket list of the great gods, and I bow here to thank you for your support!

In fact, when I passed a million words, I wanted to have an explosion to celebrate, but during this time, I have been worrying about unsolved troubles at work, and I don't have much energy to come back, and I am impetuous again, and I haven't been able to watch many games in the World Cup. When this time the matter is busy, I plan to make up for my character, at the end of July or the beginning of August, at that time, there will be more.

Thank you to the book friends who have been supporting Hui Mao!
