The road to the Industrial City is the first cement road in Datang that has been completed, with four lanes, wide and straight. Pen? Interesting? Pavilion wWw. ｂiquge。 infoThe road is lined with neatly trimmed holly, and there are flower beds at short intervals, arranged in regular patterns. It gives a wide view, neat and comfortable feeling.

The road is busy with cars and horses, and the river is endless.

Slightly different from usual, Yang Kang had already notified the traffic management department in advance, and the two lanes in the middle of the road were reserved for His Royal Highness King Liang and the grassland VIPs.

On this road, there are already special traffic managers, who are soldiers of the forbidden army, with a red armband on the sleeve of their uniform, with the words "traffic management" written on it, and patrol back and forth on horseback.

Li Su introduced the construction of the road to Wei Gongzi on the road, from cement materials to construction organization and traffic management, etc., and carried out science popularization in detail.

Soon they came to the Industrial City.

The industrial city covers a huge area, which is now thousands of acres, and there is a wall about 2 meters high outside. The gate is very wide, and there is no real door panel that can be closed, just a symbolic gate. The two stone lions at the door are very powerful.

Guarding the gate are the industrial city's own guards, and the military uniforms they wear are also the uniforms of the Tang Army's forbidden army, and they also wear red armbands with the words "industrial city".

Li Dan, director of the Industrial City Management Committee, and several leaders of the Industrial City have greeted them at the gate.

As soon as Li Su saw Li Dan, he gave him a look, meaning not to expose the identity of Wei Gongzi. Li Dan squeezed his eyebrows at him, and gestured with his hand to an OK gesture that Li Su taught him, indicating that he understood.

Entering the industrial city, there is a wide cement pavement inside, lined with neat rows of factory workshops. Around the workshop, many trees are planted, dotting the monotonous factory area.

The first thing they visited was the cold drink factory.

When they arrived at the gate of the cold drink factory, the factory director respectfully asked them to change into white overalls, and then took them inside to visit.

The first thing they visited was the ice-making workshop, where the workers demonstrated the ice-making process to the visitors, and Li Su explained the principle to Wei Gongzi and other grassland VIPs.

Next, they visited the sorbet, ice cream and other production workshops.

Finally, I went to the reception room of the cold drink factory and invited them to taste various products. Although Wei Gongzi ate a little unwell in Li Su's carriage, he couldn't help but eat another ice cream.

Then the director of the factory introduced the huge profits of the cold drink factory to the grassland guests, which shocked them greatly, and they were all thinking about how many cattle, sheep and horses they could buy with this money.

Wei Gongzi said: "After I go back, I will also build a cold drink factory." ”

Next, they visited furniture factories, embroidery factories, textile factories, handicraft factories and other factories. Almost every time Wei Gongzi saw one, he said that he would do one when he went back.

At noon, they had dinner at the Industrial City Management Committee.

Like the staff, they eat in the canteen, six dishes and one soup, although simple, but the dishes are made according to the recipes of Li Su Taobao, compared to the monotonous boiled meat and barbecue on the grassland, mare's milk, or make the grassland VIPs eat with relish.

After dinner, Wei Gongzi said, "Your cook will also give me a few, how much is it, I will buy it." ”

Li Su said with a smile: "The level of the cooks here is just very average, after you go back, send someone to my palace and let my chef help you train a few." Package you are satisfied. ”

Next, they visited the vegetable patch set aside for the convenience of eating vegetables in the industrial city, as well as the greenhouse for winter.

The afternoon tour is the Industrial School.

The greenery of the technical school is very beautiful, with a large lawn inside, and many flower beds outside the offices and classrooms, which are pleasing to the eye.

The school's office building is a small white building nestled among lush trees.

The principal, Princess An Ning, greeted them at the door of the office building. Then arrange for them to visit the classroom.

Li Su asked, "Sister Huang, what kind of class did you arrange for the distinguished guests?" ”

An Ning smiled: "Let's go listen to Ning'er's math class." ”

In a spacious and bright classroom, Li Ning'er is explaining to the students in the advanced class that the one-dimensional equation is a chicken-rabbit cage problem.

She spoke very seriously, and when she saw Liang Wang Li Su coming in with a distinguished guest, she sold it even more

force. She nodded to the visitors and motioned for them to sit at the tables and chairs specially prepared for them in the back, and she continued her lecture.

She first wrote the topic on the blackboard, and then said: "Students, today's topic is chickens and rabbits in the same cage:

Chickens and rabbits are in the same cage, with a total of 35 heads and 94 legs, how many chickens and rabbits are there? Ask the students to use the one-dimensional equation they just learned to solve it, and ask the students to think about it. ”

When Wei Gongzi saw the question on the blackboard, he was very interested, and he used his brain to think desperately, but he really couldn't figure out this seemingly simple question. He crossed his fingers and pondered it repeatedly, thinking that his head hurt, but he couldn't figure it out.

When Li Ning'er saw his appearance, she couldn't help laughing, afraid that he would see it, so she turned her back and snickered.

After a while, Li Ning'er said, "Okay, when the time comes, please raise your hand if you have a good idea." ”

At this time, the students in the classroom basically raised their hands.

Wei Gongzi was a little unconvinced, he couldn't believe that most of these people who seemed to be younger than him could be calculated.

Li Ning'er pointed to a twelve or thirteen-year-old female classmate and said, "Gao Xiaomin, you can answer." ”

Gao Xiaomin, the niece of Gao Jingming, the head of the household department, stepped up to the podium, picked up the chalk and lined up the formula on the blackboard.

Solution: If there are x chickens, there are (35-x) rabbits

2x+（35-x）×4=94

2x+140-4x =94

x=23

Rabbit: 35-23=12 (only)

A: There are 23 chickens and 12 rabbits.

Li Ning'er waited for her to finish writing and said, "Very good, Gao Xiaomin answered correctly." Use your brain more when doing math problems in the future! Actually, it's not difficult. ”

After listening to the class, Li Su and the others came out of the classroom, and Li Ning'er also followed.

Li Su introduced Wei Gongzi: "This teacher Li is the daughter of Li Xiaogong, the king of Hejian County, and the youngest mathematics teacher in the Tang Dynasty. ”

Li Ning'er couldn't help but feel a little proud when she heard Li Su praise herself. However, when he heard these two words, he stopped, was a little dissatisfied, and said, "What else? ”

"He is also the youngest director of the mathematics department. ”

Li Ning'er was still not satisfied, and said, "What else? ”

Li Su said: "He is also the chief accountant of the Datang Research Institute. ”

Li Ning'er was a little anxious, she was about to cry, and said, "What else?" ”

Seeing her anxious look, Li Su suddenly understood, and said, "It's still His Royal Highness King Liang of the Tang Dynasty, that is, my fiancée." ”
