Tang Dynasty good brother-in-law

Chapter 994 Going to Huayuan

Liu Mu said: "Then they don't pay attention to it. Treating phosphate rock with sulfuric acid and turning it into phosphate fertilizer will help increase the yield per mu?"

"The Ministry of War gave Daomen's Qinghe Temple a large sum of money to fund various researches on Qinghe Temple. In the eyes of the Ministry of War, the knowledge of chemistry is all kinds of magical explosives, or poison to kill the enemy. Qinghe Temple is expected to be available within a year. Stable glycerin gunpowder, now they are mixed with some kind of ore powder to form a block, and then detonated by charcoal gunpowder, the power is amazing."

Li Shimin's words made Liu Mu dumbfounded.

Liu Mu said: "Second brother, a good medicine for curing diseases and saving lives has become a weapon of the Ministry of War again."

"Not necessarily, in the use of mountain mining, it is still beneficial to the country and the people." Li Shimin will not mention anything that is helpful to the war.

After finishing speaking, Li Shimin asked again: "Any other interesting items in Huayuan?"

"There is nothing in Huayuan that is used by the Ministry of War for war." Liu Mu will never link Huayuan's various research with war.

Li Shimin smiled and said, "Let's go to Huayuan together tomorrow."

What Huayuan is, for the high-ranking nobles of the Tang Dynasty, there will always be a mystery.

Ordinary people in Chang'an don't care much about it.

The next day, there were only Li Shimin, Liu Mu, Dugu Lanruo, and Changsun Wugou. Except for the guards, there was no one else.

In North Jingbei, Li Shimin brought Liumu to Chang'an North Railway Station.

"The railway on the bridge seems to be more complicated. Fortunately, when the bridge was designed at that time, it was considered to be prepared for the train. The issue of whether the train enters Chang'an has been discussed for a long time by the Minister of Education. Maybe Chang'an does not need to cross the bridge from time to time. If it enters Chang'an If so, what about the city wall?"

Li Shimin was not asking for Liu Mu's opinion, but simply stating the situation at hand.

Liu Mu kept silent, just stood in front of the train and looked at this very strange guy. The Tang version of the train was very different from the locomotive in his memory.

Mainly it is ugly.

In Liu Mu's eyes, there is no sense of streamlines at all, the very bulky front of the car is even a little ferocious.

"Mighty, this is the most important weapon of my Tang Dynasty."

Li Shimin's sudden words stunned Liu Mu, and then immediately laughed: "Second brother is too right, how can the dragon chariot not be powerful."

Willow has nothing but praise for this big, clumsy front.

It is already a miracle for Datang to be able to make such a car front, and his own aesthetics does not represent Datang's aesthetics.Behemoths already have fangs, the popular type is a kind of high-speed beauty, and the ferocious feeling is a kind of mighty beauty.

While Li Shimin was waiting, two additional carriages had already been hung up at the station.

Liu Mu said to Li Shimin: "I thought the second brother would build a special train?"

Li Shimin shook his head: "The Ministry of Rites once submitted a request to build a special royal train for my second brother, but I refused. It's not the right time now, with Huayuan's production capacity last year, only two qualified locomotives could be produced. Come on, this year, the number of skilled craftsmen has increased, and the number of machines has also increased, so we can make three."

"Actually, it's not too little."

The steam locomotive seems simple, but with Datang's current technology, more than [-]% of the work of the steam engine needs to be done manually, so the efficiency cannot be improved.

In particular, Datang's current welding technology is far from up to standard, and all steam engines are riveted.

The emergence of lathes, punches, and planers can help the manufacture of small steam engines. Datang has not yet been able to mass-produce such super-large steam engines as locomotives.

"Get in the car!" Li Shimin pulled Liu Mu who was in a daze.

Two carriages, this is also a small privilege that Li Shimin, as the emperor of the Tang Dynasty, gave himself, a very small privilege.Very fine woodcarved carriages, the decoration is extremely gorgeous.

After sitting in the compartment, Li Shimin said: "I took it once when the bus was opened before, and it only takes an hour to get to the Huayuan bus from here. I asked the station, and it takes an hour and a half to load the goods."

It is only about 140 miles from Jingyang to Huayuan, so the speed of this train is [-] to [-] miles per hour.

Before Liu Mu asked, Li Shimin said: "The speed of the passenger car is 130 miles per hour, and the limit speed during the test is double this. Li Dejian wrote that the second-generation train head is expected to start mass production within three years. , to ensure that the speed of the passenger car reaches 240 to [-] miles per hour."

240 miles is [-] kilometers per hour.

Miracle, Willow can only use miracle to describe this word.

After Li Shimin finished speaking, he glanced at Changsun Wugou and Dugu Lanruo. At this time, the two were looking at the scenery outside the window. Although it was not the first time they took a train, the feeling of novelty was still the same.

Seeing that neither of the two women was paying attention, Li Shimin approached Liu Mu and asked in a low voice, "After more than 1000 years, how fast will ordinary people travel by train?"

"Twelve hundred miles per hour. But the truck is at most half of this speed, or [-]%."

"Oh, so fast?" Li Shimin was very surprised.

Liu Mu said with emotion: "Every year during the Spring Festival, trains transport at least 20 billion passengers to and from the north and south of the Yangtze River. Let's put it this way, second brother, there are railways in places you can think of, and places you can't think of."

A smile appeared on Li Shimin's face. He knew some history. In history, trains did not appear until 200 years later, and the speed was only ten kilometers per hour, which was half an hour.

Datang is also considering changing to a 24-hour day and night system, and then 60 minutes per hour and [-] seconds per minute.

However, this requires a process. Datang astronomers are constantly communicating with Rome and doing corresponding research.

There is also the reform of weights and measures. 16 taels a catty is no longer suitable, and it is inconvenient to calculate. You should consider changing to a decimal system. You can try to change it to sixteen taels a tael, ten taels a catty, a hundred catties a load, and a thousand catties a kilo. Ton.

Of course, this also requires a process.

Li Shimin said to Liu Mu: "In my lifetime, [-] miles of railways will be built in this world."

"Difficult." Liu Mu poured a basin of cold water on Li Shimin unceremoniously.

Li Shimin also understands that railways are a kind of craft, and bridges, roads, etc., and other crafts also need to be improved.

"By the way, what's in that valley?"

Liu Mu subconsciously replied, "It's not for fighting."

Li Shimin smiled: "Then, when we arrive in Huayuan, we will look at this first, to see what is magical in the valley."

valley.

In the heavily guarded valley, even the sky is blocked, hundreds of roofs block the view from high places, and no one is allowed to approach the sides of the valley. This is a no-fly zone for hang glider.

Here, Li Shimin only saw a huge light steel skeleton more than 30 feet long.

"Mu, what is this?"

　Happy New Year to all my friends.
