Liu Yulong is an old man of Huhai First Construction Company, he has been working in a construction since he graduated from Huhai Concrete Ji University at the end of the sixties, and has profound attainments in building construction and concrete technology, and it is because of this that he can serve as the chief engineer of a mixing plant. Because the first batch of concrete mixing plants in Shanghai is also the earliest batch of concrete mixing plants in the country, the chief engineer in charge of technical work is particularly important, and Liu Yulong is also in danger. Since he was in charge of the technical work of the mixing plant, the concrete quality of the mixing plant has also been well-known in the construction industry in Shanghai, and there has never been a major quality accident. However, Liu Yulong is also a relatively conservative person, and when designing the concrete mix ratio, the surplus coefficient is relatively large, which is also the characteristic of the older generation of technical experts. In their words, if you play the side ball, the surplus coefficient is not enough, then once there is a problem in a certain link, the quality accident will come to you, how can you walk by the river without getting your shoes wet?

Fortunately, in the early days of ready-mixed concrete, the profit is quite amazing, and the concrete mix is not a little higher than the design surplus coefficient, at most it is a few yuan of a cubic meter of cost increase, for more than 100 pieces or even close to 200 pieces of a cubic meter of gross profit of concrete, this is nothing. It's nothing more than wasting more cement, and the quality is more guaranteed. This is different from later, after the large-scale rise of concrete batching plants, the market competition is extremely fierce, and in 2010, the gross profit is less than 50 yuan a cubic meter, if the business volume is too small, it will lose money, because the various fixed costs are amortized, the larger the business volume, the smaller the fixed cost amortized to each cubic meter of concrete. For example, with an annual output of 100,000 cubic meters and an annual output of 1 million cubic meters, the fixed cost is spread to each cubic meter of concrete, which is nearly ten times different, and generally speaking, the break-even point of the concrete batching plant is between 100,000 and 200,000 cubic meters. Therefore, the cost of concrete materials at that time was compressed to a very low level, and the surplus coefficient left by the concrete mix ratio during the design was so low that it could not be lower, and even some had no surplus coefficient at all, which could not reach the standard value, and quality accidents were endless.

Why does Liu Yulong admire Li Ruoyu? Not only because he is the most down-to-earth and hard-working person in a mixing plant, but also because he is the only college student except Liu Yulong himself. You must know that in the early nineties, college students are rare animals, which company has how many college students, that is a kind of show off capital, no matter where you go, college students are very valued, but also the focus of each company to cultivate the object.

In a mixing plant, in addition to Liu Yulong, the chief engineer, the technical quality system also has the manager of the technical quality department, that is, the director of the laboratory Zhou Jing, this Chen Jing is not a university graduate, he is a secondary school student who graduated from the Shanghai Construction Engineering Technology School, graduated in 85 years, at that time the secondary school students were also very popular, so he did not become the director of the laboratory in less than two years. This Chen Jing doesn't like Li Ruoyu very much, because he is afraid, Li Ruoyu is a graduate of a famous university, and he is valued by the chief engineer Liu Yulong, maybe he will rob his position one day. He hangs his heart every day, and he also tries his best to suppress Li Ruoyu, and always finds some of the dirtiest and most tiring jobs for Li Ruoyu to do, such as concrete sampling to make test pieces, dismantling molds and oiling, etc., which should have been done by the test workers, but they all fell on Li Ruoyu's head.

Li Ruoyu didn't care, he was a newcomer, he should do more, he didn't expect to go to that aspect at all. In fact, Zhou Jing just wanted to bury Li Ruoyu, he let Li Ruoyu do the dirtiest, most tiring and most unskilled work, just to prevent him from having the opportunity to get in touch with key technical work, and Zhou Jing would never tell Li Ruoyu about key things, let alone lecture him. For example, as soon as there was a new variety of concrete for mix design and trial matching, Zhou Jing broke Li Ruoyu's back, he was afraid that Li Ruoyu would master these technologies and squeeze him down. It wasn't until a few years later that Li Ruoyu knew Zhou Jing's intentions, but at that time Li Ruoyu had become the director of the new mixing plant laboratory of Huhai Construction Engineering, and Zhou Jing was also reported because he ate and took the card, lost his position as the director, and became an ordinary technician. This is called good recompense for good, and evil recompense for evil.

But now, Li Ruoyu has been reborn, so he will no longer be stupid to accept Zhou Jing's domination, in his previous life, it was because he didn't understand these people's sophistication, but then he rose higher and higher, so he naturally knew all about them, and Chen Jing's methods were really not too clever. How can a truly talented person be buried like this, it is gold that shines wherever it is, even if it is buried in the sand, someone will always find him. Of course, the one who discovered Li Ruoyu was the chief engineer Liu Yulong.

Li Ruoyu said hello to He Liangyou and the others, and went straight back to his dormitory. I haven't lived in it for half a month, and there is a lot of dust in this dormitory where four people live, Li Ruoyu put down his luggage and cleaned it carefully, after doing this, Li Ruoyu looked at the time again, and it was almost twelve o'clock at noon. It's time to call Wu Mengyao to report that she is safe, and by the way, ask her to ask someone to bring a letter to her parents, and she has arrived safely.

Coming to the office of the technical quality department, no one has come to work yet, there is an office phone here, but it is a long-distance function, but for Li Ruoyu, who has crossed over, this is not a problem. Because he later learned how to make long-distance calls from the chief of staff, and now he is back in need of it.

Li Ruoyu pressed the dial key with a trembling hand, and then entered two special numbers, so that he could make a long call. Then press the area code of Yandu, and finally press the phone number that Wu Mengyao said. When he finished pressing the phone number, Li Ruoyu felt his heart pounding. I don't know if Wu Mengyao is in the office at this time? Also, there should be other people in her office, so it seems that she can't even say affectionate words.

"Beep-toot-" The phone went through quickly, but no one on the other end didn't seem to have lifted the microphone yet. After about five seconds, a familiar voice came from the phone: "Ah, Ruoyu, is that you?" A female voice on the other end of the phone whispered excitedly.

It's Meng Yao's voice! Li Ruoyu was also very excited, he hadn't seen Wu Mengyao for a few days, and he missed it very much, if he had a mobile phone like in later generations, it wouldn't be like this, but unfortunately this was in the nineties. Even Big Brother, which is like a brick and worth more than 10,000 yuan, has not yet been popularized, and even if there are probably many places, there is no signal.

"Meng Yao, it's me! Now that I'm back in the unit, I've been missing you so much these days! Li Ruoyu will not hide his thoughts about Wu Mengyao in his heart.

"Me too! Do you know? How worried I am these days, I blame you for this, so that I can't eat and sleep well for a few days. I guess you slept like a pig on the train, right? Hee-hee! Wu Mengyao whispered. She's also afraid of being heard, and now that it's lunchtime and everyone in the office has gone to eat, she doesn't want anyone to hear it. On the one hand, because people are relatively conservative in this era, and on the other hand, Wu Mengyao is also very shy.

"It's all my fault, my Meng Yao is not hungry, right? You're already slimmer, if you can't eat anymore, wouldn't you be slimmer? I still like a slightly plump Mengyao! Hehe! Li Ruoyu quipped.

"You're begging to be beaten! Villain! Think of things you shouldn't think! When Wu Mengyao said this, her whole pretty face turned red, and she looked at the door of the office while saying that, she was afraid that someone would come in or hear these embarrassing words at the door.

Li Ruoyu also heard it, Wu Mengyao's voice trembled uncontrollably when she said this, such a pure girl is really rare, Li Ruoyu half-jokingly said: "Mengyao, where am I broken?" I didn't think about anything, I was thinking too much, right? ”

"Flim Flam! I wonder if you're lying to me! I still feel like I'm in a dream. Do you know? I've had a crush on you since my freshman year of high school, and I'll always remember that day! On the first day of school, there was a wooden boy sitting next to my table, and he blushed when he saw me, and he didn't even know where to put his hand, but this man quickly captured my heart. He is always wearing a white-washed tunic with a middle-part head, he is not handsome, and he can't speak, but he not only has the best academic performance in the school, but he is also a person with a great sense of justice! I remember that shortly after the start of the first year of high school, one night after the evening self-study, I went home alone, it was very dark, and there was no one on the street, only the classmates who went home by themselves after the evening in our school. My house was also a few hundred meters away from the street, and when I walked to the back of the street, something happened that I will never forget. A couple of second-rate students from our school stopped me there, saying they wanted to play games with me. Those people were all squinting, and several pairs of eyes kept staring at me, how could I not know what they were trying to do? I was terrified, I wanted to run away, but they stopped me, at this time I was really desperate, I could only shout loudly, but I shouted several times, and no one appeared. I know that this time I'm going to be finished, and if I am insulted by a few second-rate people, I might as well die, and even I have thought about it, if that's the case, I will commit suicide, and I can't live in this world with an unclean body. Just when I was caught by a few second-rate people and was about to be insulted, a man appeared, he was very witty and brave, and I didn't know where he found a flat pole, and three strokes and five divided by two knocked out two of those second-rate people, and the other two ran away when they saw that the situation was not good, but this man didn't say anything, and ran away. Although I didn't see what he looked like in the dark, I took advantage of his inattention to rub some blood on the corner of his coat behind his back, which I had bitten with my teeth and fingers. The next day, I noticed that the male classmate sitting next to me had blood on the corner of his clothes, which was probably not very noticeable, and he didn't notice it. But there is one more person in my heart from now on! ”

Wu Mengyao finished this story as if in a dream, and her eyes were already moistened. Finally, she paused for a few seconds before spitting out a few words: "That person is you, Li Ruoyu!" ”
