Since Ying Feiyu returned to Xianyang.

During the day, he was busy with government affairs, and even at night, he was busy in the study until midnight before going to bed.

It wasn't until all the soldiers who rescued Haixing returned that a smile appeared on Ying Feiyu's tired face.

took a gap and called Ying Heng and Huang Yuan to the palace.

"Your Majesty!"

"I've seen the emperor!"

The two bowed.

The last time we met was at the funeral of General Wang.

Everyone's mood was very low, and they only took a look at each other, and they didn't even say a word.

I was thinking about finding a gap during this time to report on the recent situation of various factories, and I was summoned!

"Brother Huang, you finally remembered us!"

Ying Heng squinted his eyes and said with a smile.

"Alas! So much has happened in this time! ”

Ying Feiyu shook her head helplessly.

The two of them knew what he was referring to, and their mood was instantly low, "Wu Chenghou's incident was an accident, no one expected that there would be a sudden aftershock!" ”

Wang Jian passed away suddenly, and his affairs were naturally rumored.

This includes the whole process of his rescue.

It makes the people sigh!

"Alas! It's not just ...... Master passed away! ”

Ying Feiyu smiled bitterly and shook his head, "Haixing County suddenly moved, and it hurt the people a lot!" In addition, the rescue personnel and materials could not arrive in time, which also had a great impact on the rescue work! ”

In Haixing County, he has seen too many things that are forever separated, which is really sad.

"No way! The emperor's brother also said just now that the ground movement happened suddenly, even if it was immediately dispatched, it would take two days to get from Xianyang to Haixing County at the earliest! ”

Ying Heng explained.

"Yes, Your Majesty, even if it is collected and dispatched from nearby counties, it will take a day or two! There's no way around it! ”

Huang Yuan also nodded repeatedly.

In their opinion, the train is already a very fast means of transportation.

In the past, communications and transportation were very backward, and the materials did not know when they would be delivered.

Not to mention saving the people!

By the time the rescuers arrived, the best rescue time had already been missed!

"If we can hurry up and arrive the day after the ground movement, then at least half of the people can be saved!"

Ying Feiyu said to herself as if she hadn't heard the two of them talking.

"Arrived the next day? How is this possible? Unless there are wings flying over! ”

"Even if you fly, it's not that fast!"

After hearing this, the two looked at each other and smiled, thinking that it was impossible.

Even if it is a bird with wings, it is impossible to fly from Xianyang to Haixing in a few hours.

It's more than 2,000 miles in between!

"You're right, I'm just going to fly!"

Ying Feiyu's eyes suddenly became clear, and he said to the two of them with a firm gaze.

The two looked at each other again, their faces full of incredulity.

After a while, he suddenly reacted, "Your Majesty is talking about hot air balloons, right?" ”

"But the number of people that a hot air balloon can carry is too small!"

"Yes! Didn't Your Majesty say that it is not safe to fly high in hot air balloons? If the army is sent to the rescue in a hot air balloon, how many hot air balloons will have to be sent? And for the soldiers, it's too dangerous! ”

The two were not optimistic about the proposal.

We can't let the lives of the soldiers go unnoticed in order to support the disaster area!

"I'm not talking about hot air balloons!"

Ying Feiyu finally showed a smile on his face.

"Huh? Not a hot air balloon? ”

The two tilted their heads, trying to think.

After a while, Huang Yuan's eyes suddenly lit up, "Your Majesty is talking about the kind of machine that can fly in the air, right?" ”

He remembered that many years ago, His Majesty had mentioned it on the train.

Speaking of the future train, it will be a piece of cake to travel thousands of miles a day.

When technology reaches a certain level, it can reach thousands of miles away in an hour!

What's even more powerful, it can build a machine that can fly people in the sky, and the speed is extremely fast!

It is estimated that what His Majesty is talking about now is this kind of machine!

"That's right! It's an airplane! ”

Ying Feiyu fixed his head.

Since arriving in Haixing County, he found that the delivery of relief materials was too slow, and he made up his mind to start researching airplanes when he returned.

In the event of a war or natural disaster, it is the fastest way to transport soldiers and supplies by plane!

Don't look at the current Daqin like a pool of spring water, the waves are not shocked.

No one can say what will happen after that.

The hearts of the people are separated from the belly, and the rebellion never stops!

If you can't keep it, there will be war one day!

Not to mention natural disasters!

Daqin has a vast area, and natural disasters occur from time to time, big or small!

If such a thing happens again, with airplanes, casualties can be greatly reduced!

"What? Plane? Brother Huang, do you really want to build an airplane? ”

Hearing the conversation between the two, Ying Heng suddenly became interested, and his two eyes were as wide as copper bells.

"That's right!"

"That's it...... Is it the kind that can fly in the sky? ”

"Yes!"

"Can you really fly?"

"Seriously!"

Ying Feiyu lost her temper when he asked.

If you can't fly, why do you put a lot of effort into studying airplanes?

"That'...... How many people can you carry at that time? ”

Ying Heng was so excited that he even stammered when he spoke.

"If it goes well, maybe two or three hundred!"

Ying Feiyu made a rough estimate and spoke.

"Two or three hundred ......?"

Ying Heng's eyes purred, and he said happily: "Although there are not as many people as the train, two or three hundred is not a lot, which is much stronger than a hot air balloon!" Send 100 units, and you can carry 20,000 or 30,000 people! ”

"Your Majesty, it doesn't matter how many people are carried, the most important thing is how safe it is?"

Huang Yuan raised one of the most critical questions.

If it's as unstable as a hot air balloon, what if it carries a large number of people?

Everyone is going to die together, and it's more lively to get together, right?

"As long as the manufacturing is successful, safety is definitely fine! Even the accident rate is lower than that of a train! ”

"What? Lower than a train? ”

This time, the two were even more shocked than before.

You know, since the train has been running, there hasn't been a single accident at all.

If the accident rate of airplanes is lower than that of trains, does it mean that accidents are impossible?

"How is this possible? Airplanes flying in the sky are definitely more dangerous than trains running on the ground! ”

Win Heng asked incredulously.

"Brother Huang is right! It's because it's dangerous to fly in the sky, so be more careful! Every take-off and landing of the aircraft needs to be carefully checked to make sure it is correct before taking off! ”

After some explanation, the two also understood a lot.

The plane is not free of danger, but it is necessary to be sure that there is no danger before it can take off!

This is to avoid surprises!

"Such a miraculous machine must be very sophisticated!"

Ying Heng sighed and began to imagine the general appearance of the plane.

"Hmmm! That's right! ”

After speaking, Ying Feiyu ordered someone to carry a thick stack of drawings.

This is the thickest drawing the two have ever seen since they built the machine!
