After the authorization ceremony, Sun Zesheng declined Zhang Xinglong, and Wang Xiaofeng insisted on asking her to have a meal. After sending them outside the Yamei Daily Chemical Factory, he turned around and returned to the company.

The factory area became deserted, and most of the managers, security guards and other employees who worked overtime also went home. In the next day and a half, there will basically be nothing that requires them to stay, and they can go back and spend the weekend.

.

Sun Zesheng walked to the door of the chairman's office, knocked on the door, then opened the door and walked in.

Song Jiayi was sitting on the boss's chair, raising her slender feet on the table and rubbing her painful ankles with her hands. Seeing Sun Zesheng come in, she quickly put her feet down. "Xiaosheng, your classmate is not inviting you to dinner.

?”

Sun Zesheng smiled and said, "It's not fun to eat with them. I prefer to eat with Sister Song."

Song Jiayi felt sweet in her heart, and she stood up, "In that case, let's go have dinner. Should we go to my house or go to a restaurant?"

Sun Zesheng said: "This is not urgent. Sister Song, have you got the 3D printer I asked you to buy for me?"

Song Jiayi nodded, "I bought it. I had people put the goods in the warehouse that were just delivered yesterday evening. I haven't had time to tell you yet. Do you want to go take a look now?"

Sun Zesheng nodded, "I want to see."

Song Jiayi took out the key to the warehouse and went to the warehouse with Sun Zesheng.

This is a domestic 3D printer. Domestic research in this area is not much behind foreign countries. The technical level of this 3D printer is still quite high. The printing accuracy can reach 0.1 mm and the maximum printing size is 1.8 meters. That is to say

This 3D printer can print items with a length, width and height of no more than 1.8 meters.

Of course, the price of such a 3D printer is not cheap. It costs four to five million, which is not within the reach of ordinary people.

Sun Zesheng nodded with satisfaction. This 3D printer is enough to meet his current needs. With it, he can manufacture many things in small batches, and some plans can be put into practice.

Sun Zesheng took Song Jiayi out of the warehouse, and then found a small restaurant near the Yamei Daily Chemical Factory and had a meal together. Then, Sun Zesheng returned to the warehouse, took the manual, and began to study it carefully.

.

Song Jiayi didn't know what Sun Zesheng wanted to do, so she didn't ask. She just stood aside and helped Sun Zesheng. However, her feet were still a little inconvenient after all. Sun Zesheng was afraid that she would be too tired, so he helped her for a while.

After she was busy, she was asked to go back to the office to rest.

The manual for the 3D printer was thick. Sun Zesheng flipped through it and quickly figured out how to operate this expensive instrument.

To operate a 3D printer well, the biggest technical difficulty is to use a computer to create a data model for the 3D printer. As long as the data model is established and input into the 3D printer, the 3D printer will work like an ordinary printer.

, print out the items corresponding to the data model.

For example, let's say you want to use a 3D printer to print a cylinder. Its data model is to evenly cut the cylinder into countless small slices, with a thickness that can reach the maximum accuracy of the 3D printer, and then use the 3D printer to cut these small slices.

Print out one by one, and every time two small sheets are printed, the printer will spit out adhesive to bond the two small sheets together, and this cycle will eventually form the final product.

Of course, some processing is inevitable in the end, but the general process is like this.

Sun Zesheng has encountered a lot of trouble recently, including the Yanjing Gang, Deputy Mayor Wang Baowang, etc. These are the masters who may be slapping him behind his back, so it is necessary to take some targeted preventive measures.

Sun Zesheng's plan is very simple, which is to use a 3D printer to make some gadgets, and then use these gadgets to closely monitor Wang Baowang and others, the backbone of the Yanjing Gang, to obtain evidence of their crimes, and then wait for an opportunity to bring them down.

Of course, it is not easy to achieve this. Although science and technology are developing rapidly these days, there is still an unreachable distance from his ideal state. In particular, what Sun Zesheng has to do is to improve on the existing technology.

Basically, it is not that difficult to combine and transform.

Sun Zesheng had to consult the information while referring to the advanced technology in Tianjixing 3000, integrating contemporary and future technologies, and designing some products that could not only meet his needs, but also be quite concealed and practical.

Time passed unknowingly, and it was night in the blink of an eye. Sun Zesheng still could not finalize the draft. During this period, he tried to print a few things with a 3D printer, but the printed things were still quite different from what he expected.

If there is a gap, we have to tear it down and start over.

"Xiaosheng, don't be busy, come and have some food." Song Jiayi came in carrying a brand new insulated rice bucket. She pulled a table over, took out all the food and put it on the table.

Sun Zesheng put down the things in his hands and walked to the table. He smelled the food and said, "It smells so good. Is it Sister Song's craftsmanship?"

Song Jiayi looked at Sun Zesheng in surprise, "How did you know it was my craft?"

"Of course you can smell it." Sun Zesheng smiled, picked up the chopsticks and handed them to Song Jiayi, "Sister Song, eat with me."

Song Jiayi's appetite was not big and she was full quickly. She scooped some porridge for Sun Zesheng and put it next to him. Then she quietly watched Sun Zesheng eat the food she made by herself. When Sun Zesheng finished eating, she again

Start tidying up.

"Xiaosheng, do you still have to work the night shift tonight?" Song Jiayi asked.

Sun Zesheng nodded, "Well. I want to get things out as soon as possible. The sooner the things come out, the greater the benefit will be to me. By the way, Sister Song, I may have to trouble you tomorrow. I made a list, please

You go buy them back for me tomorrow."

After Sun Zesheng handed the list to Song Jiayi, he reinvested in the design of new products. Song Jiayi moved a chair and sat aside to watch. The temperature at night in November was relatively low, but Song Jiayi

The look in Jiayi's eyes when she looked at Sun Zesheng was hot.

Song Jiayi heard people say more than once that Sun Zesheng's success came too easily, but looking at how busy Sun Zesheng is now, who can say that Sun Zesheng didn't put in hard work that ordinary people can't believe?

In the blink of an eye, it was eleven or twelve o'clock at night, and Song Jiayi couldn't hold on any longer, so she tilted her head and fell asleep.

Sun Zesheng inadvertently raised his head and took a look. He was moved and pitiful at the same time. He looked at the time and found that it was indeed late. He stood up, walked to Song Jiayi's side, and hugged Song Jiayi.

Song Jiayi was startled and woke up.

Sun Zesheng said softly: "It's okay, Sister Song, you can continue to sleep."

After hearing this, Song Jiayi found a comfortable position in Sun Zesheng's arms and continued to sleep.

Sun Zesheng carried Song Jiayi and walked into the chairman's office. In addition to being used as a sofa, the sofa here can also be used as a bed. Sun Zesheng pulled out the bed cabinet under the sofa and put Song Jiayi on it.

Above, he went to a corner of the office, turned out the mattress, and laid it on the sofa bed. Then he lay down on the sofa bed, stretched out his arms, and held Song Jiayi in his arms.

Song Jiayi naturally found a comfortable position in his arms and continued to have her sweet dream.

There was no words all night. In the early morning of the next day, Sun Zesheng felt a little itchy on his face. He opened his eyes in a daze and looked sideways. Song Jiayi was pillowing on his shoulder, and a strand of black hair fell on his face.

on, making him itchy.

Sun Zesheng smiled and hugged Song Jiayi tightly.

Song Jiayi woke up and looked at Sun Zesheng who was so close. She suddenly remembered that she slept with Sun Zesheng again, and a seductive blush appeared on her face.

Sun Zesheng's lower abdomen felt hot and he murmured: "Sister Song."

"Yeah." Song Jiayi responded, her voice was lazy and as alluring as she wanted.

Sun Zesheng couldn't hold himself back, and thrust his head forward, his big mouth captured Song Jiayi's alluring lips. Song Jiayi made a sound, opened his mouth, and Sun Zesheng's big tongue penetrated into Song Jiayi's vagina.

Tan's mouth was chasing Song Jiayi's fragrant tongue wantonly.

Song Jiayi closed her eyes and hugged the little boy in front of her tightly, who was ten years younger than him.

Sun Zesheng's hand scratched Song Jiayi's back, and then followed the hem of Song Jiayi's clothes and penetrated into Song Jiayi's clothes, covering the fullness of Song Jiayi's chest, which was soft and firm.

It made Sun Zesheng feel as if he was about to burn.

Sun Zesheng's mouth left Song Jiayi's fragrant lips. Song Jiayi was a little reluctant to let go. She opened her eyes and glanced at Sun Zesheng.

Sun Zesheng's eyes were about to burst into flames, "Sister Song, I want you."

Song Jiayi stretched her head forward, and her sweet tongue took the initiative to enter Sun Zesheng's mouth. This was her attitude.

With Sun Zesheng's tacit consent, Sun Zesheng hurriedly took off his own clothes, and then took off Song Jiayi's clothes, and the two of them were naked together.

Song Jiayi's body became as red as cooked shrimps. Sun Zesheng treated Song Jiayi's body like the most precious treasure, kissing her whole body, and then took Song Jiayi's grape-like vagina into his mouth*

*, sucking greedily, and with the other hand, grabbed Song Jiayi's other breast and kneaded it vigorously.

Sun Zesheng aimed his hard cock at Song Jiayi's moist softness. When he pushed forward, he leaned into Song Jiayi's ear and said, "Sister Song, I love you. I will be good to you all my life."

Song Jiayi's long arms hugged Sun Zesheng tightly, and her two slender legs tightly wrapped around Sun Zesheng's waist. With a cry of pain, a wisp of blood flowed out from where they were joined.

…

After a long time, Sun Zesheng roared, and white magma spurted out and poured into Song Jiayi's body. Sun Zesheng lay on Song Jiayi's soft body, and Song Jiayi stroked Sun Zesheng's back, "Xiaosheng, you feel better.

Is it done yet?”

Sun Zesheng turned over and got off Song Jiayi, "Sister Song, what do you mean by this?"

Song Jiayi said: "Xiaosheng, you have been very unhappy these days. I don't know how to help you. All I can give you is my body. People don't say that women's bodies are the best for men.

The harbor?”

After hearing this, Sun Zesheng felt both love and pity. He held Song Jiayi in his arms, opened his mouth wide, and kissed Song Jiayi's lips again.

…

By the time the two of them got up from the sofa bed, it was already three o'clock in the morning. Song Jiayi, who had scored three goals, was weak and weak, which made Sun Zesheng almost fall apart. Fortunately, today was Sunday, and there was nothing going on, except for them.

Outside of the factory, there are only security guards guarding the door. Otherwise, Song Jiayi would not be able to see anyone.

After having sex with Song Jiayi, Sun Zesheng felt that the boredom in his heart was really relieved a lot. Song Jiayi's thoughtfulness and tenderness made him feel that he was no longer alone and gave him support. Although this

This kind of support is not very strong, but it is indispensable.

There was convenience food in the chairman's office. Sun Zesheng and Song Jiayi ate some briefly, and then Sun Zesheng continued to run to the warehouse and started working. Not to mention, the efficiency was much improved compared to yesterday. Song Jiayi was still like last night

Likewise, sitting nearby and watching, she stared at Sun Zesheng, her eyes showing deep love, attachment and satisfaction.
