Those who really have an identity and have enough talent are very reliable in themselves, and Wu Cao has thought about it in detail on the road. Only 27 people entered the small conference room, among which Lu Chengqing was the general person in charge of the project and was directly responsible to Wu Cao.

"Eighty zhang long, sixteen zhang high, and twenty zhang wide!" As soon as Wu Cao opened his mouth, he frightened people.

Something so huge.

"King Qin of the Tang Dynasty has secretly decreed that Yaozhou must complete the first aerial fortress of the Tang Dynasty within seven months. The Goguryeo people will never keep their promises, so we must let them know how powerful our Datang is. ”

After Wu Cao finished speaking, he took a few steps back and cast a slide on the curtain.

Wu Cao chose the early nineteenth century, the German Zeppelin, which was a pure hard airship. Coupled with the improvement of science and technology in later generations, Wu Cao predicted that Datang would make it with all its might, and it would be able to produce a more Haode airship than the original German one.

"Record the order!" Wu Cao's voice was sharp, but serious.

"Datang's first air fortress has a take-off load of 450,000 catties and a flight speed of 500 miles per hour. You remember, this is the art of immortal work. ”

Wu Cao mentioned the art of immortal work, and there was no need to say anything more.

Naturally, Yaozhou has a set of confidentiality manuals.

The steam engine is within the scope of special secrecy, this immortal art should be a special grade, Li Changxin said that this has to be watched to death, just this big guy who can fly, he can bring 450,000 catties of importance, an hour and 500 miles, this is to be learned, it is too dangerous.

Wu Cao took a sip of water:

"Steam workshop, this palace will give you the blueprints. Hongu wants the most exquisite steam engine. Don't talk about difficulties, this palace only needs to see the result, and the steel you need, go to the steel mill to ask for it. ”

"Iron and steel mill, you must be careful about the skeleton of the air fortress, it must all be special steel, not too much, as long as you provide 100,000 catties, but the rivets must also be special steel. All machines can be called up by your steel mill first. ”

"Weaving workshops, leather workshops. Hongu needs a fabric that does not leak, whether it is pigskin. Sheepskin. Cowhide. Or silk, linen, or whatever. Not only should it not leak, but it should also be strong, and most importantly, it should have a certain amount of expansion. You look at it, and this palace only needs the result. ”

"Carpentry workshop, bamboo workshop. This palace wants you to choose the strongest one. The lightest material. Stock up for use. ”

"Immortal Workshop, pick out the most brilliant Taoists, and pass on their methods of refining the Qi of Flying Heaven in this palace."

“zuihou。 Boat workshop. The construction of the big ships will begin, and by tomorrow April, at least 16 large ships of 500 materials can be launched, and at the same time, the construction of four large ships of 1,000 materials will begin in Laizhou. The steam engine for marine high-power propulsion, the steam workshop must be made for the main palace no matter what, it must be a high-quality product, and there must be no flaws! ”

There was no answer, just a quick voice recorded with a pen.

"Lu Fu Yin, whose territory is Yincheng County?" Wu Cao asked.

"If you go back to Princess Mingyue, it is the territory of Datang." Lu Chengqing is a ruthless man, he has only been in the Qin Palace's mansion for a year, and he has changed from an ordinary scholar to a real ruthless man, who has been on the battlefield, executed criminals, and personally beaten the whip. He understands one thing, for the sake of the country, all those who stand in the way will be crushed!

"There is the most haode coal there, the mining workshop ......" Wu Cao shook his head after thinking about it, with the current Jishu of Datang, find a coal mine there, and then start digging, and then select good coal I don't know how long it will take, I am afraid that it will be a waste of manpower and a mistake, so Wu Cao changed the order.

"First select the most haode coal in Yaozhou Coal Mine to keep, Lu Fuyin pay attention to Yincheng County!"

Is it to be careful?

Lu Chengqing knows very well that although there are still six or seven hundred miles away from Yaozhou, since there is very haode coal there, this is a reason, either trading, or supervision, or direct control.

That night, Lu Chengqing began to draw land in Yaozhou.

The chief and deputy directors of the eight major workshops, the chief engineer of Jishu, Lu Chengqing, Li Chang, and the general of the guard, a total of 27 people, stood on the top of this valley in the middle of the night.

"Here, the sacred object was built according to the valley, and the two ends of the valley mouth were sealed, and no pedestrians were allowed on the valley. This secret can be well protected. "Li Chang has always thought that this place is a good place, and there are no trees in it, it is basically a rocky valley. Originally, it was intended to be used as a secret warehouse, and now it is used to build airships.

Lu Chengqing also recognized the location.

However, the blacksmith said: "This artifact is eighty zhang long, I am afraid that even its own weight plus the weight that can be carried is enough to six or seven hundred thousand catties, such a heavy thing flies into the sky, a certain person can see this miracle in life, and it is worth it to die." ”

Li Chang was more direct, kneeling on the ground and shouting: "The Tang Dynasty is mighty!" ”

The most powerful people in the Yaozhou Workshop were excited about the artifact, and they believed that as long as His Royal Highness King Qin asked him to make it, it would be a matter of effort, and it would definitely be possible to fly.

Wu Cao sat in his room, but he was not so confident.

First of all, the first point of material.

There are two main materials, one is the keel, and the other is the bracket. In later generations, aluminum alloys, or even titanium alloys, can be used, which are light and strong. But only steel can be used here, although the design drawings have been demonstrated in the modern Peking University Institute of Technology, and great efforts have been made to reduce the amount of steel used and make a more reasonable design.

But Wu Cao is still very worried about whether the quality of the steel can meet the requirements.

The wire can be pulled thinner and wound tighter.

Another material, that is, the cloth used to inflate, if it does not meet the requirements, the original design of 36 airbags will be increased by the number of some more, then it will increase the weight of the bracket, steel wire, cloth and so on.

Then the worry is about the steam engine, although it is a steam turbine type, but it is not able to achieve enough inflatable liliang, propulsion, etc., whether it can control the open flame, because after all, hydrogen is used.

On the other side, in the middle of Qinwangzhuang.

Li Yuanxing was also a little worried, the content he was worried about was completely different from Wu Cao, and Wu Cao was worried about whether it could be made better. Li Yuanxing was worried that Li Er would not want to occupy his airship, and then let himself supervise the country, and he ran to Liaodong. That's the real big trouble.

Tonight is the day when Li Yuanxing returns to modern times, and after Li Yuanxing checked his luggage again, he put the list left by Wu Cao in his arms.

Martial law was already under fire outside the study, and it was only a few minutes away from crossing.

Cui Yanyan was sitting and reading a book in the lounge next to the study, tonight was her night, and she hoped that she could wait for His Royal Highness King Qin to come back at close range.

In modern times, it was already two o'clock in the morning, and Li Lanshan was sitting on the computer watching the Xuanwumen TV series.

After Li Yuanxing came back, he pushed the box to the corner of the room and collapsed on the bed naked. Li Lanshan didn't look back, but asked softly: "Are you in a bad mood?" ”

"I ordered the airship to be built." Li Yuanxing said with a smile.

Li Lanshan slowly closed the computer and turned around: "Who offended you, your airship was originally used by Jihua for Tufan as a logistics force, and now that you are in such a hurry to build it, I estimate that it will take at least a year for that airship." ”

"Underestimate my subordinates, the first seven months, after which you can become more proficient. By next year, steel production will go up. I have my own thermal power plant, I dare to try electrolytic aluminum, and in five years, there may be the first real giant super airship, and then I will name it, Qinwang! ”

Li Yuanxing said confidently.

Li Lanshan smiled and kissed Li Yuanxing's face lightly: "Next year, you will have a power plant the year after tomorrow, and you will secretly smile." ”

"Strive for next December, this is still seventeen months!" Li Yuanxing's words made Li Lanshan laugh non-stop.

"Tell me who offended you."

"Goguryeo has cleaned me up, and on the morning of the third day after I return to the Tang Dynasty, I will run naked in Chang'an. I calculated the distance, it was almost five to seven kilometers long, and I still needed to keep my image, so I couldn't go too fast, and at a speed of three kilometers per hour, I had to walk for an hour. ”

After Li Yuanxing finished talking about the events of the day, Li Lanshan giggled non-stop.

"You don't even sympathize with me."

"How about a bet between the concubine and you?"

"What a bet!" Li Yuanxing was a little confused, and he didn't know what Li Lanshan meant.

Li Lanshan walked to the desk and wrote something, then sealed it in an envelope, sealed it with wax in front of Li Yuanxing, and then handed it to Li Yuanxing: "I believe in my guess, I also believe in my man, and I believe even more that my man is absolutely not a fool in the Tang Dynasty, the king of Qin, so this is the result of my guess." After the end of the day, you open it and read it, and after reading it, it burns, because what is written on it is not understandable by the Tang people, and it is not suitable for seeing! ”

"Good!" Li Yuanxing put the envelope away.

Li Lanshan helped Li Yuanxing pull open the quilt, and her tone was a little serious: "The morning after tomorrow, you are going to court, although it is the first time you go to court, there will be no results, but you should have a good rest in the past two days!" ”

"You haven't said what you're going to bet on?" Li Yuanxing asked.

What does Li Lanshan want to bet on? was asked by Li Yuanxing like this, and her mind changed again.

The man who originally thought he knew himself better must know more than Ye Qiushuang. But now that I think about it, what's more interesting than that.

He is supporting Li Yuanxing in his own way.

Ye Qiushuang is also supporting Li Yuanxing with her methods, and she is helping Li Yuanxing supervise the production of airships.

This is a big project, and it can be said that for Datang, it is no less influential than the construction of the Tang Palace.

Not comparable.

"If I win, I want you to buy me a villa in Singapore. The top gorgeous kind, and by the sea, there is a beautiful beach, and the most important thing is that in addition to the house, the surrounding environment must be large enough, the garden or something must be there, and the swimming pool is indispensable! Li Lanshan looked like a lion's mouth. (To be continued......)
