Tang Dynasty good brother-in-law

Chapter 1022 A Dangerous Weapon

Li Shimin ordered to make Chang'an City lively.

The attendant bowed and listened to the order: "Yes."

"Also, we need to find a good excuse to postpone the New Year's sacrifice to heaven and earth, or not to sacrifice this year."

Li Shimin had no choice but to give such an order. All the important ministers of the Shangshu Province, except Du Ruhui who was still in Chang'an, the rest were all in various parts of the Tang Dynasty.

Of the important ministers in the cabinet, only Shangshu of the Ministry of Justice is in Chang'an.

Let's talk about the six departments, the six departments are currently relying on a servant to lead the officials of the headquarters to support the normal operation of the Tang Dynasty. The rest of the people either want to fight, or they want to participate in this expedition Goguryeo battle.

All the generals in Chang'an City, except for Dugu Xiude, who guarded Chang'an and couldn't move, all the generals who could run ran away.

On New Year's Eve, the palace was extremely quiet.

Li Shimin began to urge: "Order, let the palace people have a good time, and let me support the New Year's atmosphere in Taiji Palace. Tell everyone, don't speculate, don't talk too much, it has something to do with the fate of the Tang Dynasty, and whoever has trouble will do it." who beheaded."

The attendant went down to make arrangements.

This is a chance for everyone in the Tai Chi Palace to relax.

When Liu Mu arrived, he invited Li Shimin, the queen, and the fourth lady to spend New Year's Eve with him.

"Your house is very deserted."

Liu Mu replied: "The eldest sister is in the West Wing State, the second sister is in the Mediterranean Sea, and the third, fourth, and fifth sisters are all in Africa. Maybe it's possible to go to the West Wing State to celebrate the New Year. It's too far away to know the news. , it is not convenient to contact. What's more, tonight is New Year's Eve, and they can't come to me even if they are in Chang'an."

Li Shimin had given his orders, and Liu Mu came to greet him and left.Also let everyone in the Taiji Palace relax, and the people in the palace don't have the guts to really have a carnival once.

Liu Mu lived in the original East Palace, and the new Palace is in the state of digging the foundation, and it will take at least three to five years before it can be repaired.

Li Shimin does not intend to use too much manpower and resources.

In Li Shimin's mind, manpower and resources should be used to build railways and bridges, not the palace.

When walking back, Liu Mu complained: "Ma Zhou ran away and took half of Wenyue Pavilion's elite to the north. If there were no regulations to keep enough Chang'an defense forces, it is estimated that all Wenyue Pavilion people could run away. I don't know why they are so excited, but I said that this time there is no merit."

"Seventy-five percent of the important ministers in Chang'an City have gone north. The older they are, the more they don't want to miss it. My second brother said a long time ago that this is a ceremony, not a war."

Liu Mu looked up at the moon, took a pipe and lit himself: "Second brother, there are still 47 days, according to the calculations of Yanzhou Donggang, after 44 days, the sea ice will no longer affect the ships, and there will be southwest wind after 47 days. "

"What about the airship?" Li Shimin was concerned about the airship.

There was a gleam of joy on Liu Mu's face: "If all goes well, we will be able to fly for the first time in fourteen days."

"Good!" Li Shimin was happy.

Liu Mu persuaded: "Second brother, this thing is not safe. This is just the first one, and some parts can be made better. The construction period is too tight. And hydrogen is a very explosive gas, so the airship needs to fly at least [-] times. After hours, after several improvements, after ten years, the second brother will be able to ride."

Although Li Shimin knew very well, the airship must not even be able to get close.

Once Baiguan knew that it was flying by a huge bomb, he would definitely remonstrate, and would never let himself get close to the airship.

"pity."

After Li Shimin finished speaking, he pointed at Liumu: "You can't ride either."

Liu Mu was not as excited as Li Shimin, and he didn't care much about the airship Liu Mu, so he said very flatly: "I didn't plan to ride in the first place, if I did, Lan Ruo would definitely be worried."

What Liu Mu said made Li Shimin speechless.

Liu Mushuang said: "That's not as scary as I imagined, but if there is an accident after flying a hundred times, it's hard to say."

"It's really dangerous?" Li Shimin's face was a little more nervous.

"It's not serious, but it's true. Because the technology is immature, according to my assumption, this airship will need at least five years of technical precipitation and accumulation. Let's put it this way, the quality of steel, or the formula of special steel, airbags The making of it, and the rubber. Especially the rubber."

Li Shimin heard Liu Mu mention the word rubber many times.

Li Shimin asked Liu Mu: "Is it true that you can't find a rubber tree?"

"Yes, about [-] miles to the east, you can find it there. This is another story. In fact, a safe airship uses an aluminum alloy frame, uses safe helium gas, and is powered by batteries and internal combustion engines."

After Liu Mu explained, Li Shimin counted down the lines with his fingers.

In fact, neither of these items can be completed within a few decades. The oil alone is enough for Datang to study slowly for more than 30 to [-] years.

"It seems that the airship can only be used as a deterrent weapon, and Datang can't have only one."

Li Shimin's ideas may be common in later generations, but in this era, he can only be called a genius.

Li Shimin asked Liu Mu again: "What will happen if there is an accident?"

What will happen?
Liu Mu didn't know how to answer for a moment.

Li Shimin didn't urge him to ask, and kept waiting for Liu Mu to think.

When walking back to the front garden of Liumu Mansion, Liumu said, "I remember a very famous boat. First of all, let me declare that although this boat also uses a large amount of hydrogen, it has a hard shell and an aluminum frame."

"En!" Li Shimin nodded.

Liu Mu then continued: "That ship is called the Hindenburg. It may have been flying for five years after it was built. In the year before the accident, this airship seemed to have completed almost twenty transatlantic flights."

"From the European continent with a width of five thousand miles to the one in the New World."

"Yes. It takes six days and six nights to go back and forth." Liu Mu added.

Li Shimin was very happy to hear this data: "This speed is quite fast, flying thousands of miles in six days and six nights, good."

"This ship had an accident, and it seems that someone has studied it. I remember that the hydrogen gas was ignited by thunder and lightning and heavy rain, and it burned to ashes at a height of hundreds of feet in about 30 seconds."

Li Shimin made a decision immediately after listening: "Flying is not allowed in thunderstorm weather, it will be safer."

Liu Mu said to himself: "I remember some studies have said that if the material of the skin is not easy to be burned, then even if it catches fire, it will not be fatal. This is too professional. I have only heard of it, but I don't know it very well. The progress of a technology may be made on the basis of countless sacrifices and failures, and no one is perfect."

"It makes sense."
