On the morning of February 27, Xu Fang drove his Volvo to the gate of Dongda. Yao Chi eBook Du Lingling was standing at the gate of the school, surrounded by several boys.

"Beauty, I'm xxx in my junior year in the Department of Electronics, let's leave it to my friends. ”

"I am the little Taibao of Dongda's double-flower red stick, and if you report my name in the future, no one will dare to bully you. ”

Du Lingling was wearing a bright yellow cashmere coat, struggling to avoid the nasty boys around him. "Get out of the way, my boyfriend will be here soon. Du Lingling said with a straight face.

"Di" Xu Fang pressed the horn of the car, and then parked the car next to Du Lingling, which scared several boys to the side.

"It's great to drive a Volvo!"

"Nouveau riche, no su zhì!"

Xu Fang stuck his head out of the car window, looked at these scolding boys, and said with a smile: "Ye just didn't have a vegetarian, get out." ”

Several boys flashed in Xu Fang's loud cheers.

Du Lingling looked at Xu Fang vividly, his eyes were full of happiness, he opened the passenger door and sat in.

"Aren't you bringing Sister Wan'er with you?" Du Lingling asked with a wink when he saw Xu Fang driving away.

"She went on her own, and we met at the door. Xu Fang said.

After a while, we arrived at the scene of the patent exchange meeting.

"Xu Fang, I'm here. Sima Wan waved her hand at Xu Fang.

Du Lingling was happy when she saw that there was a handsome young man beside Sima Wan at a glance, it seemed that Sima Wan was no longer her rival in love, she already had a boyfriend.

Du Lingling also waved his hand to Sima Wan and shouted, "Sister Wan'er." ”

Xu Fang saw Bai Feng beside Sima, and stepped forward to greet him with a smile: "Bai Gongzi, I haven't seen each other for a long time, why did you deceive Sima and ignore me?"

Bai Feng also smiled and said: "How can it, Wan'er and I are still just ordinary boyfriend and girlfriend relationships, and we still need you to match more, brother!"

"Yo, Lingling, listen to it, it's a relationship between men and women, and you still need me to match, I can't care about it, you can handle it yourself. Xu Fang joked.

Lingling smiled and stretched out his hand to Bai Feng and said, "Bai Gongzi, I am Du Lingling, Xu Fang's girlfriend, take care of me in the future." ”

Bai Feng looked at Lingling and said, "Xu Fang is not a worry-free man, you have to watch it." ”

Xu Fang listened to Bai Feng's provocation, pretended to be angry, and said, "Sima, take good care of the man in your family, like a woman, go home and let him kneel on the keyboard." ”

Sima Wan watched them squeeze against each other, and said with a smile: "Come on, don't make trouble." It's not too early, so let's hurry in and see if there are any good projects. ”

The four of them walked into the exhibition hall together, talking and laughing.

Xu Fang is very interested in all kinds of patents, but it seems that most of them are really useless, and many of them are taking off their pants and farting - this is a big move. Xu Fang saw that Sima Wan was still discussing with the patent inventor one by one with great interest, and Xu Fang said to Bai Feng, who was accompanying Sima: "Bai Feng, I'll go to the side for a while, and you will call me after you finish reading it." ”

Bai Feng nodded and said, "Okay, you go find a place to rest for a while, and I'll call you if you have something." ”

Xu Fang found a booth in the exhibition hall and sat on the booth, while Du Lingling was as inseparable as a fart.

Xu Fang and Du Lingling sat together and chatted. Du Lingling saw a very interesting person, pointed at him and said to Xu Fang: "Brother Xu, you see that uncle looks like he has a 'sex'. ”

Xu Fang looked in the direction of Du Lingling's finger, and sure enough, there was a very unusual uncle sitting behind a table, and there was a patent name display board on the table. "There's really a 'sex'. Xu Fang sighed.

This uncle is at least fifty years old, and he has already lost his head, his sparse hair has formed a split head shape that surrounds the center, his face is rectangular, and his big eyes with many eyelids are crossbowed outward like goldfish eyes, he is wearing a bright red tracksuit, holding a big beer belly, and he is wearing a pair of army green "color" slacks underneath.

"Let's go, Lingling, let's see if Uncle's patent has the same 'sex' as his person. Xu Fang stood up and walked towards the uncle. Lingling also followed.

Xu Fang read clearly the words on the display board as he walked: Super Purification Water Alkali Technology.

"Uncle, what's the use of your super purifying water alkali technology?" Xu Fang asked as he stood in front of his uncle.

When the uncle saw that someone finally asked about his invention, he was very happy to say to Xu Fang: "Young man, my ion water purification technology is a very advanced and very valuable invention, which can bring a revolution to our country's water treatment industry and make our country a world-class power in water treatment." ......”

Xu Fang really couldn't listen to the uncle's endless praise of his invention, and stretched out his hand to make a stop gesture. "Stop, uncle, tell me about your invention, I believe it's a very meaningful invention, but you always have to make me understand why it's so meaningful, isn't it?"

The uncle pulled Xu Fang and Du Lingling to sit down and said, "Young man, my invention is very profound, I will tell you its principle and function in the most simple and popular language." ”

The uncle took out a thick stack of texts from his schoolbag and put them on the table, saying, "These are all the technical descriptions and test numbers of this invention." After several years of research, I finally discovered a very miraculous ion, which can adsorb the water alkali and some large particles of suspended solids in the water to itself, precipitate, and finally form a large particle directly taken out of the water, which can reduce the hardness of the water, so that the water alkali is not adsorbed on the inner wall of the water equipment, so as to improve the efficiency of the water equipment and reduce the difficulty and number of maintenance of water equipment such as boilers, which is a very useful invention. ”

Xu Fang grew up in the north, knowing that the water quality in the north is very hard, and often produces water alkali, even at home, the water alkali of the kettle thermos must be cleaned regularly, not to mention the heating and water supply equipment, if the water alkali is not cleaned for a long time, it may cause a big accident. This invention may be of some use.

"Uncle, can this ion be produced in large quantities? Is it very costly?" Xu Fang felt that the market prospect of this patent should be very good, but no one cared about it until now, it must have its own defects, otherwise it would have been put into production a long time ago.

The uncle looked at Xu Fang embarrassedly, "revealed" a shy smile, and said: "The extraction of this ion is indeed a little difficult, mainly because the extraction environment is relatively harsh, so now the cost of mass production is very high. When the uncle saw Xu Fang's brows furrowed slightly, he immediately added: "But now I have a good solution, but I don't know much about this solution, and I don't have the money to practice, so I want to sell this patent to a rich man, so that it can be published as much as possible." ”
