After pondering for a while, Lu Bu couldn't help but explain to Huang Chengyan: "The principle that the hot air balloon can be lifted into the air is that after the hot air balloon is heated, the mass of the hot air balloon is lighter than the air, so it can be lifted into the air. ”

"But airplanes are different, airplanes have a density that is heavier than air. The airplane I designed has wings on both sides, which you can think of as wings, and a tail behind it, which is the tail. ”

"There is a power plant on the plane, and when the plane glides on the ground at a certain speed, the wings generate upward buoyancy, and the plane can take off."

After listening to Lu Bu's explanation, Huang Chengyan blinked his eyes and decisively said that he didn't understand.

Although Huang Chengyan has conducted a lot of scientific research, he is really a layman for aircraft, and for him, it is a new knowledge.

Lu Bu didn't intend for Huang Chengyan to understand this matter at once, Lu Bu found out the core technology that had been prepared a long time ago and submitted it to Huang Chengyan.

After Huang Chengyan took the material, he immediately watched it, and his eyes became brighter and brighter, and he soon fell into it.

The previous hot air balloon has fulfilled people's dreams of life.

But hot air balloons really don't really fly.

This plane is!

The wings have wings that allow them to soar freely in the air and fly fast.

What usually takes days or even a dozen days to reach can now be reached in just a few hours.

If the aircraft can really be developed, it will definitely be a qualitative leap for Dahua Technology, and it will greatly improve people's lives.

Of course, the biggest role is still in the military.

In the future, if they want to attack the Sabbatical Empire or the Roman Empire, they don't need to think about the long distance, the difficulty of transporting troops, and the difficulty of transporting grain and grass.

With airplanes, the transportation of both materials and people will be simple and fast.

What a great and amazing invention!

Seeing Huang Chengyan, who was completely caught in it, Lu Bu also shook his head helplessly.

At this time, the palace eunuch saw the emperor's expression and was ready to step forward to wake up Huang Chengyan and let him leave.

This Lord Huang is also really, and he doesn't understand the rules at all.

After meeting the emperor, you have to leave immediately, how can you stay in the palace and not leave?

The little eunuch just walked over and was about to remind Huang Chengyan to leave, but he was stopped by Lu Bu and motioned for him to retreat.

If you don't go crazy, you won't survive.

If it weren't for this madness, Huang Chengyan would not have achieved so much.

Well, can't I give you this place?

Lu Bu left here, and then ordered someone to take all the information of all the young heroes over the age of seventeen and under the age of twenty in the city of Nanjing.

This time, Lu Bu decided to find a fast son-in-law from it as soon as possible, and then immediately let Lu Lingqi marry.

After all, the customs of this era are like this, seventeen years old, is not young.

If you drag it any longer, you will become a big girl, and it will be even more difficult to get married at that time.

Now, it can't be left to her temperament.

Not long after, the information of the young talents in the entire city of Nanjing was presented on the case.

Lu Bu couldn't help but carefully select them one by one.

And the emperor's movements were soon known to Princess Lu Lingqi.

Lu Lingqi was so angry with her father that she almost cried.

However, she was also scared.

She knows her father's temperament, and she absolutely knows everything.

As long as it is determined by the father, it is almost impossible to change.

What to do? What to do?

Lu Lingqi secretly became anxious.

After a long time, Lu Lingqi gritted her teeth, finally gritted her silver teeth, and made up her mind to run away from home.

However, now in the palace, it is heavily guarded, and it is not said that you can just leave.

Lu Lingqi first spent all the palace maids serving around her, then wrapped a few changes of clothes, brought gold and silver, and prepared to slip away quietly.

After thinking about it, he finally left another letter and tucked it into a book on the table.

When he is gone, there will be chaos in the palace, and I believe that my father will definitely see this letter at that time.

But now it is not visible.

Lu Bu's management of his children was not as strict as that of the previous dynasty.

Whether it is a prince, a prince, or a princess, you can leave the palace at will.

Of course, when you leave the palace, you must also have a report, and you must bring a guard to go out.

It's easy to get out of the palace, but how can you take your package out with you?

Swaggering out with the package will definitely arouse the suspicion of others, and when the time comes, I am afraid that I will be arrested as soon as I leave the palace.

After frowning and thinking for a long time, Lu Lingqi finally thought of a good way.

That is, he wrapped his package in a box, and then pretended to be a gift for Mrs. Zhao, and ordered the little girl to carry it with him.

In the past, she would often go to the Zhao Mansion and give each other some gifts, so as not to arouse the suspicion of others.

Sure enough, with this method, Lu Lingqi quickly slipped out of the palace.

The first step was successfully completed, and the next step was the second step, how to get rid of the guards and palace maids around him.

After thinking about it, Lu Lingqi soon came up with a good idea.

She pretended to go to a store to buy some gouache rouge, and then the store was mainly for women's products, and most of the people in the store were women.

Those guards, naturally, were not easy to follow, so they waited outside.

Only Lu Lingqi's two personal maids followed.

Lu Lingqi separated the two maids, quietly took out the package in the box first, and hid it in a hidden place in the store.

Soon, after the two maids came back, Lu Lingqi ordered them to guard the box, saying that she was going to make it easier.

Lu Lingqi quietly took her package, went out to buy a man's clothes, and quietly changed them.

So far, her plans have been perfect.

But after she actually ran out, Lu Lingqi was at a loss again.

I'm running out, but where are I going?

Under the whole world, it is not the king's land, and the shore of the division is not the king's minister.

The whole Dahua is under the rule of her father, no matter where she goes, she will be noticed by her father soon, and she will soon be arrested by her father.

Where the hell are you going?

After thinking about it for a long time, Lu Lingqi suddenly had an idea, that's right! Go find Brother Zhao yourself!

Find Brother Zhao and let Brother Zhao intercede for himself!

Thinking of Zhao Yun and Brother Zhao, Lu Lingqi's eyes couldn't help revealing endless tenderness.

Well, now that Brother Zhao is in the Guishan Autonomous Region, then he will go to Guishan himself.

There are two ways to get to Kushan, the first is by water, and the second is by land.

However, if she had traveled by land, it would have been nearly 20,000 miles, and she did not know how many years she would have to walk.

What's more, the road ahead is difficult and difficult to pass.
