Li Shimin has been living in Li Tai's Shu Wangfu for the past few days, and on this day he called Wang Haoran over and talked about the construction of the railway, and it turned out that he wanted to take Zhongcheng as the meeting point to lay railways in Gaochang, Goguryeo, and Hangzhou.

This is a great thing, although such a big project will definitely mobilize the people, but at this time the Tang Dynasty is not the Qin Dynasty that built the Great Wall, nor is it the Sui Dynasty that opened the canal, the Tang Dynasty is fully capable of completing such a big project without encroaching on the interests of the people, and even can drive the economy of one party.

Zhongcheng can be said to be Wang Haoran's masterpiece, Wang Haoran is naturally concerned about the development of Zhongcheng, once these three railways are completed, Zhongcheng is really the name of the Tang Dynasty, and it is only a matter of time before the future prosperity surpasses Chang'an. There is also a reason why Li Shimin did not choose Chang'an as the radiation point, the railway leads to Hangzhou is nothing, but the road to Gaochang and Goguryeo, which have not been surrendered for a few years, can bring prosperity everywhere, and will also make the radiation point a place where people and snakes are mixed, and there are many hidden dangers.

"Then what does Your Majesty need your brother to do?" Wang Haoran said with interest, it is naturally a good thing that Midtown can have such an opportunity, but how can it be more exciting than the big business coming to the door?

"Datang is the only one who has the technology and experience to build a railway, and I can only leave this matter to you to plan, you will send someone to inspect the route one day, design a reasonable route, if it passes, then such a big business will be done for you." Li Shimin did not reject businessmen, but he felt a little bored when he saw Wang Haoran's expression that lit up as soon as he made money. He really didn't understand what kind of person Wang Haoran was, things that didn't make money but benefited the country and the people, Wang Haoran didn't do less, and felt that the face of a businessman should not appear on Wang Haoran.

Wang Haoran responded happily, and after going back, he called Wang Jingxiu, Ma Jingluo, and Yu Zizhao over, all three of whom had experience in inspecting routes. The reason why Wang Haoran did not call Yu Zhaoyun, who also had investigation experience, was because Yu Zhaoyun still had to continue to study the ignition device.

Speaking of ignition devices, we have to talk about the study of fuel power. In recent years, due to the shortage of manpower in the study of iron ships, this research has been intermittent and the progress has been slow. Now that the Explorer has departed, it will be able to concentrate on this research.

Although most people have devoted themselves to the research of iron ships over the years, Xiaoyu and Ruyi have been researching ignition devices. Now that they have both researched it, if the battery can't be studied, then they can only use the ignition device researched by Xiaoyu.

After developing the ignition device, Xiaoyu gained a lot of experience, and she has obtained permission from Wang Haoran to build a hydroelectric power station for research, which is still under construction.

Xu Mian made a new metal some time ago, he called it Xuangang, Wang Haoran felt like tungsten steel no matter how he looked at it, hard and brittle. According to the usual practice, Xu Mian made the filament of the dark steel and handed it to Xiaoyu to try to make the filament. The filament is bright, but it is much dimmer compared to the filaments of other materials. The advantages are still obvious, the Xuangang filament has been lit continuously for more than ten days, but the filament has not changed a little, that is to say, the filament can withstand higher temperatures, and if the hydroelectric power station is completed, if a higher voltage is added, perhaps the brightness will be much better.

One day, Wang Haoran suddenly received a letter from home, which was sent by his mother Liu Xiaomei, about Xiaoyu's life events. Originally, Liu Xiaomei and Wang Furen didn't worry about Xiaoyu's marriage, because Wang Haoran has always been very assertive and will definitely arrange it for Xiaoyu, but Xiaoyu is now eighteen years old and is a big girl, but Wang Haoran's brother didn't react, and Liu Xiaomei became anxious.

Wang Haoran understands that in fact, everyone lives in universal values, regardless of right or wrong, scientific or not, as long as it is a universal cognition, it is the truth. For example, the social system of later generations is scientific and democratic, but the people of the Tang Dynasty will definitely not be able to accept it, so the Tang Dynasty can only continue to implement the feudal system at present; For example, the love advocated by various businesses, media, authors, etc. for selfish interests in later generations is simply regarded by everyone as a god-like existence, and it is almost kneeling on the ground, is this a reasonable and practical concept? Definitely not, but the public thinks so, then love is sacred.

Xiaoyu's matter is the same, at the age of eighteen, she is still just a little girl in the eyes of later generations, but at this time, it seems that she is a big girl who should have married a few years earlier. Wang Haoran has been in Datang for ten years, he is changing Datang, and Datang is not changing him in the same way? In the face of thousands of years of culture, Wang Haoran is still inevitably assimilated in some aspects, so Wang Haoran has no objection to his mother's desire to find a husband's family for Xiaoyu.

Agree to agree, but Wang Haoran still respects Xiaoyu's personal wishes, and Xiaoyu has to choose her husband's family, and he is responsible for checking it.

Wang Haoran called Xiaoyu over, handed her Liu Xiaomei's letter, and asked, "What do you think?" ”

Xiao Yu's face was red, and she said timidly: "Brother...... I...... I'm already interested in someone......"

"Oh? Who is it? Wang Haoran was surprised, Xiaoyu has always been out of the door, but he didn't expect to find the person he liked right under his nose, it must be someone in the institute, Wang Haoran was a little ashamed, as a brother, the sister who gets along day and night doesn't know if she gets along with others.

“…… Zhaoyun. Xiaoyu said timidly, for fear that his brother would take the case and trouble Yu Zhaoyun.

"It was him! So what did he say? Wang Haoran is still quite satisfied with Yu Zhaoyun, the Yu family is also a big businessman, and Yu Zhaoyun has a cheerful personality and quick thinking, and he will definitely be able to make a difference in the future, and it is not bad for Xiaoyu to marry him.

Seeing that his brother did not object, Xiaoyu breathed a sigh of relief and replied: "I want to wait for the electric light to be researched before talking about marriage, so he promised me to come to the door a few years later to propose marriage, so we have never told my brother about it." ”

Wang Haoran pondered for a while, and felt that it was necessary to make it clear to Yu Zhaoyun in person, so he asked Zeng Chengyong to call him over.

As soon as Yu Zhaoyun entered the door, he saw Xiaoyu making eye contact with him, guessing that Wang Haoran already knew about the two of them, and sat on the side with a smile and waited for the future eldest brother to ask.

"Tell me, what do you want to do about the two of you?" Wang Haoran asked directly.

"It all depends on what Xiaoyu means, I have already told my family that I can marry Xiaoyu at any time. Xiaoyu wants to wait until the electric light is researched before talking about marriage, and I respect her opinion, because I also know that if Xiaoyu researches the electric light, the significance is far from her personal gain. Yu Zhaoyun said.

After some investigation, Wang Haoran recognized the two of them, and also respected Xiaoyu's decision, although Wang Haoran had no intention of advocating the theory of equality between men and women, but the status of women is too low at the moment, and it is necessary to have a strong woman who can shake this concept, after all, there is no Wu Zetian in today's history.
