Daming: If I find a great-grandson, I will teach an emperor through the ages

Chapter 4 The idea of ​​flying into the sky
Cao Wei and Cao Ying, father and son, one sipped the wine while the other wiped away tears.

Cao Wei also really didn't know how to solve it, the closest relatives were about to leave, if it was him, I'm afraid it would be no better than Cao Ying.

What's more, Cao Ying is only this year.

He was too young for parting.

That is to say, Cao Ying's upbringing experience is different from that of ordinary people. If he were the second young man of the same age, he would suffer from so many blows in a day, and he might directly collapse emotionally.

After a long time, Cao Ying finally stopped crying in the silence between the two.

"Father, is it... that the doctor is wrong? Why don't we go to another place to find a doctor to take a look?" Cao Ying said softly, with the last glimmer of hope in his tone.

Cao Wei shook his head, and said with a "bitter" smile at the corner of his mouth:

"Don't you know about Old Li's medical skills? You were seriously ill when you were nine years old, and he dragged you back from the gate of hell. He said that you only have one year to be a father. That's probably true."

As he said that, Cao Wei looked at Cao Ying with concern and kindness. A gust of night wind rushed into the room, and his face flickered under the dancing candlelight.

"For the last year of being a father, I will be content to be by your side. It's a pity that one year is too short to see you marrying a wife and having children..."

In the end, Cao Wei couldn't help the corners of his eyes getting wet, and he couldn't bear the parting either.

Hearing what he said, Cao Ying was moved, grateful, and ashamed.

Speaking of getting married and having kids...

Cao Wei is now in his thirties, but he is still alone. This is all because of Cao Ying, who is his son.

When Cao Wei took in the young Cao Ying as his son, it became difficult to marry a wife.

After all, no one wants to marry their daughter to a man who has a half-grown son.

Even though Cao Wei is handsome and outstanding, some girls don't care about Cao Ying's existence, and their families will not agree.

At this time, people's thinking is too conservative, thinking that if they are not their own sons, they will not be of one mind and one mind with themselves, so what should they do if they fight for family property with their own sons?

Such dramas are constantly being staged in the land of China, and there are many stories left behind.

One thing more is worse than one thing less, no one dares to gamble.

This has caused Cao Wei to go from being a spirited young man of 20 back then to now being alone in an empty house at the age of thirty-one.

Cao Ying suddenly felt that his cheeks were hot, as if on fire.

Cao Wei delayed his lifelong happiness because of him, but now that he has recovered his memory, he wants to leave him?

Cao Ying suddenly felt that she really deserved to die!
He has decided!

He wants to spend the last year with Cao Wei, the palace...

I won't go back now.

Grandpa Huang also had Zhu Yunxie and Zhu Yunqiu by his side, so it shouldn't be a big deal for him to go back later.

"Grandfather, wait another year..."

Cao Ying is already full, and has already reached the age where she can drink.

That night, both Cao Wei and Cao Ying drank a lot of wine and talked a lot.

As for what was said, they can't remember...

Early the next morning.

When Cao Wei opened his eyes, he felt the pain of a hangover.

His drinking capacity is really not good, and he almost never drinks at all. Yesterday was a special situation.

[Countdown to return: 360 days, 16 hours, 53 minutes and 17 seconds]

Glancing at the beating timer, Cao Wei got dressed and got out of bed.

After waking up Cao Ying, the two took advantage of the cool weather in the morning to do a set of boxing in the yard.

Afterwards, Cao Wei simply prepared breakfast. After the two of them had eaten, Cao Wei picked up the hoe and left the house.

Over the past ten years, most of their father and son have repeated this kind of life.

Cao Ying stayed at home alone, but she couldn't read the books she usually read.

A young man's thoughts cannot be hidden and cannot be hidden for long.

He finally decided to stay with Cao Wei, but he couldn't restrain his yearning for his grandpa Zhu Yuanzhang, and he was eager to repay him for his safety.

Although so many years have passed, in the perception of Zhu Yuanzhang and others, Cao Ying, no, Zhu Xiongying is already dead.

But Cao Ying still wanted to say something to Zhu Yuanzhang:
Grandpa Huang, I am not dead, I am living well.

Then, here comes the problem.

If Zhu Yuanzhang knew that his grandson was not dead, he would definitely take him back to the palace.

Then Cao Ying would not be able to accompany Cao Wei for the remaining year.

So Cao Ying had to find a way to inform Zhu Yuanzhang that he was still alive without leaving Cao Wei.

Cao Ying thought about this method for a long time, until dusk fell and Cao Wei came back, but she couldn't figure out what to do.

His imperial grandfather Zhu Yuanzhang was the emperor of the Ming Dynasty. He could send many people to look for him with just one sentence. It was only a matter of time before he was finally found.

Can he control Zhu Yuanzhang not to send people to find him?
I'm afraid not!
The old man has never been threatened or controlled by others. As long as he thinks it is right, he will do it and no one can stop him!
This unique courage is also the reason why Zhu Yuanzhang was able to sit on the dragon chair step by step from a little beggar who couldn't even eat enough.

Now Zhu Yuanzhang's courage not to be coerced and controlled by others has become Cao Ying's worry.

Sorrow!

Cao Wei who returned home saw Cao Ying's absent-mindedness.

"Ying'er, what's the matter, are you worried about the result of tomorrow's ranking?"

Cao Ying looked at his clothes that were soaked with sweat and nodded.

Cao Wei picked up the kettle and took a sip, then grinned.

"Why worry about this? You work so hard every day, so there's no reason why you won't be named on the list."

"Father said so."

Cao Wei blinked at him suddenly: "Do you still remember what I told you before?"

Cao Ying didn't react for a while.

Cao Wei waved to him and walked towards the courtyard: "Come."

When the two came to the courtyard, Cao Wei took out an object, and when it was unfolded, it turned out to be a Kongming lantern.

Cao Ying was a little puzzled, and asked:
"It's not a festival at this time, so why put Kongming lanterns?"

Cao Wei waved his hand: "Just let it go."

Cao Ying did as he said, and after lighting the candle on the base, the Kongming Lantern slowly rose into the sky.

"Do you know the origin of Kongming Lantern?" Cao Wei asked suddenly.

Naturally, Cao Ying couldn't help it.

"There are many theories, the most credible of which is that Mr. Zhuge Wolong during the Three Kingdoms period used it to warn and transmit military liaison signals."

Cao Wei nodded: "Then do you know the principle of Kongming Lantern ascending to heaven?"

Cao Ying thought for a while, and said, "The heat generated by the burning candle gathers in the lampshade. The lampshade is made of paper and is extremely light. The heat carries it up."

"Yes, relying on the principle of thermal expansion and cold contraction, the air will become lighter after being heated and expanded, just like we burn charcoal for heating in winter, the hot air always goes up first,

Kongming lanterns rely on hot air to expand and become lighter to generate upward buoyancy, making it overcome gravity. "

Cao Wei turned his head to look at the Kongming Lantern that had risen very high in the twilight, "I said before that I could send people to the sky, and that's what I was talking about."

Cao Ying's eyes suddenly widened, with an expression that said, "Don't joke with me."

"This...how is this possible? Kongming lanterns and candles are so light, but people are so heavy..."

"Then what if a big enough Kongming lantern is made? It's so big that a person is like a candle on it."

Cao Ying was immediately shocked by Cao Wei's whimsical ideas!

Big enough to be like a candle...

Cao Ying really couldn't imagine how big the Kongming Lantern would be.

Like a house?
or bigger...

"But...Father, the candle of the Kongming Lantern has burned out, won't it fall when there is no heat?"

"If you make a large enough Kongming lantern in this way, wouldn't anyone who goes up it be sure to die?"

Cao Wei turned around and looked at him deeply, "Yes, so we need the help of others, the help of craftsmen, and let them help us make something that can control heat, similar to a valve.
If you control the heat, you will also control the rise and fall. There will be no turning back once you go there, and the material of the huge Kongming lantern cannot be pasted with paper. It is too unsafe. It is necessary to make a soft, light, and airtight Excellent fabric. "

Cao Wei laughed: "Those scholars and gentlemen can't do this, only the craftsmen of Ming Dynasty can do it."

After hearing this, Cao Ying nodded in a daze, her eyes full of thought.

He didn't expect that those craftsmen who had never been inconspicuous were so important.

"Father, can what you said really be done?"

Cao Wei only said one sentence, but Cao Yingru was enlightened.

"Now you know that Kongming Lanterns can fly because you have seen,

However, before the Kongming Lantern appeared, would anyone have thought that candles could float in the sky? "
