Regarding the tide of other princes being crowned emperors caused by Liu Bei, Wang Xuan's meaning was very clear, and he didn't care about it.

"They like to toss how much they like, let's do our own thing, and after the political system is thoroughly improved, I don't think the wife Cao has the ability to stop the footsteps of the army, when the time comes, the army can be pushed flat, while pushing flat, while building." Wang Xuan gently rubbed a piece of jade pendant in his hand and said casually.

This is a gadget that has been refined in the past few days, refreshing the mind, having a certain gathering effect on the aura, and slowly improving the wearer's system to achieve the effect of prolonging life.

This thing was refined for Liu Bei, Wang Xuan hoped that Liu Bei would live as long as possible, saying that it has been 196 years now, although historically, Liu Bei died in 223 years, but although he knows what will happen now.

Isn't there a sentence called 'born in sorrow and died in peace', in history, Liu Bei's life was upside down, it was indeed enough to be particularly sorrowful, is this the secret of Liu Bei's life for more than 60 years?

Generally speaking, in addition to the founding emperor, most of the emperors in later generations were short-lived, in Wang Xuan's opinion, the living conditions were too good, facing so many harem concubines all day long, in order to maintain the majesty, it was inevitable to squeeze it out early, anyway, Wang Xuan was afraid that Liu Bei's death would delay his major event.

For the jade pendant sent by Wang Xuan, Liu Bei felt a slight lightness on his body as soon as he started it, and his mind was a little clearer, and his face suddenly showed joy, after learning that it was refined by Wang Xuan himself, Liu Bei hung it on his neck without saying a word.

Liu Bei has long experienced Wang Xuan's magic, not to mention that he can always take out all kinds of exaggerated things from his chest, that is, the bronze tripod when he sacrificed to the sky, which has already made Liu Bei stunned.

Afterwards, Wang Xuan also specially instructed Liu Bei to put away the bronze tripod, in fact, Wang Xuan didn't expect that the bronze tripod would become the coordinate of luck and luck, is it because it is a vessel to worship the sky?

After this matter was settled, Wang Xuan did not go home directly, but wanted to go to the scientific research institute, Liu Bei was also interested after hearing about it, so he followed him, and when he went out, he happened to meet Zhang Fei and Guan Yu, who came to Liu Bei to eat and drink this time, so they also made an appointment to go together.

Recently, Wang Xuan is experimenting with the railway, anyway, the current iron production is rising rapidly year by year, so he is ready to build several main trunk lines in Dahan.

Speaking of railways, the general impression in people's minds is that they came from the United Kingdom, and the earliest horse-drawn carriages were used to travel on the tracks, in fact, it is recorded that horse-drawn carriages have appeared in ancient Greece more than 2,000 years ago along the wooden tracks, of course, there are some claims that the Qin Dynasty of the same era, and there are similar facilities.

For the railway, Wang Xuan attaches great importance to it, and the carrying capacity and speed of this thing far exceed the current four-wheeled carriage.

Compared with the two-wheeled carriage, the carrying capacity of the four-wheeled carriage can reach about four times, and even if the horse-drawn carriage is used, the carrying capacity can also reach ten times that of the four-wheeled carriage, and because of its safety, it can be driven day and night, and the speed is incomparable, especially in this special world, the endurance and speed of the horse far exceed the normal standard, according to Wang Xuan's estimate, there is no problem at all in maintaining the speed of forty miles.

In this way, traveling thousands of miles a day is really no longer a fantasy, but should be a daily state.

In Wang Xuan's mind, an important factor that plagued the land area of various dynasties in Chinese history was 'speed'.

The speed of information transmission, the speed of troop mobilization, the speed of material mobilization.

In ancient times, many times the emperor had changed his stubble, and the border areas didn't know it, this kind of thing really happened more than once, and there were really a lot of short-lived emperors.

The speed of information transmission is too low, so that the farther away, the less control the imperial court has, that is, the local officials and local wealthy families have made a big incident, and when the information is transmitted to the central government, it may be about a year, so how can the central government manage.

It may have been two years since the incident was made to send a new official...... This is still an official who did not die directly on the way, after all, not everyone is a Tang monk, and he will not die in ninety-nine eighty-one difficulties, under the medical conditions of ancient times, it is not uncommon to die halfway after a long journey for a year.

Therefore, the railway and the canal connecting the north and the south must be built, which can greatly shorten the communication cost between the two places, effectively ensure the centralization of power, and only with a larger land area and a longer rule, Wang Xuan can absorb more luck.

When I arrived at the scientific research institute, today is the time to agree to test the railway, the railway, this thing, seems simple, two parallel rails can be, but in fact it is not so, after all, it is not a simple construction of a straight road, not to mention, in the turning of a piece, according to different terrain, it is necessary to consider many details such as angle slope.

"Where are the railways and railcars?" The carriage did not go directly to the research institute, but came to an open area fenced outside the city, and after getting out of the carriage, Zhang Fei looked at the empty place and couldn't help but shout.

"Back to Marquis Wu Yong, this is the test site, the ground is laid with a railway, you can see it when you get closer, as for the iron car, it is in the room over there." The person in charge of the test site respectfully greeted him and explained to Zhang Fei.

The physical test site this time is very large, with a test site with a radius of 10 square kilometers.

"The test site is so big!?" Zhang Fei said with some surprise.

"Isn't this nonsense, this needs to be tested for different soil qualities, climbing different slopes, turning, maximum bearable breakage angles, etc., you know!" Wang Xuan stretched out his hand and pulled Zhang Feipao aside, and walked towards the test venue.

"Uh...... I don't understand. Zhang Fei understood what every word meant, but when combined, it was a bit difficult for Zhang Fei.

"If you don't understand, don't ask, follow the mess!" Wang Xuan didn't even look back, and went back directly.

Zhang Fei's face was even darker, Guan Yu looked cool, his slightly narrowed Danfeng eyes and Liu Bei looked at each other, holding back a smile, in fact, they didn't understand what they were talking about at all, taking Zhang Fei out of the house has this kind of benefit, there is no need to be afraid of embarrassing things at all, Zhang Fei will take care of everything, and it will be good for these two people to follow behind and develop obscenely.

The person in charge of the reception quickly lowered his head, looking like I hadn't heard anything, hadn't seen anything, and I didn't exist.

Walking into the test site, sure enough, the terrain has been modified a little complicated, fortunately the site is large enough, otherwise it would not be possible to simulate so many terrain features.

Zhang Fei was used to it, and he didn't have the idea of being angry, so he walked two steps quickly to the front, and looked at the dark railroad tracks buried in the ground in amazement, "This is the railway!?" ”
