And this matter naturally can't escape the ears and eyes of the eldest son Fusu.

After hearing about it.

Fusu couldn't help but smile.

I sighed for the whimsy of winning immortality.

Immediately, he suddenly had a special idea.

That is, he Fusu has never known how his talent is learned.

Today, there is such an opportunity.

Why don't you go over and take the test.

It's also good to see, what is the level of your own talent and learning in the folk?

This idea, after appearing in his heart, quickly haunted Fusu's mind.

After thinking about it for a while, Fusu finally made up his mind that he would also take this exam.

And just as Fusu was thinking about taking the entrance exam for the academy.

Win Changsheng at this moment, but he has arrived at the mansion of the public loser.

"Nineteen sons, the old man has lost his welcome, it's rude!"

Seeing that Win Changsheng came over, the grandfather who lost the Shangzai, and the grandfather who lost the profit hurriedly smiled at him.

"Where is it, where is the public loss, where is it now?"

Win Changsheng smiled, looked at Gong Yili, his eyes fixed on the pretty figure of Gong Yi Panruo, and opened his mouth to ask about the whereabouts of Gong Yi Shangzao.

"In the past few days, he has been sent to Guanzhong by His Majesty, and I don't know what he is doing......

Gong Loser replied.

"Oh."

Win Changsheng was a little disappointed.

Seeing this, the public couldn't help but ask.

"The nineteenth prince came to find Shangzao, is there something wrong?"

"Well, there are some things that I want to make, something that can fly into the sky!"

Win Changsheng nodded, and said to Gong Gong.

He wants to make nothing else.

It is in the system that the hot air balloon that has just been obtained.

However, this thing is quite technical.

In particular, there are a lot of materials that the current Great Qin can't find.

Therefore, Win Changsheng wanted to come over to find the public and discuss together.

How to make out a real hot air balloon.

However, he was not at home.

That's all I can do.

At the same time, the public loser is shocked to win Changsheng.

"What did the nineteenth prince say about flying into the sky? But a joke? ”

"How can it be a joke? I don't like to joke with people! ”

Win Changsheng Chaogong said with a loss.

He only likes to joke with girls like Gong Yi Ruo, but he doesn't like to joke with old men like Gong Yi Li.

And at the same time.

In the heart of public profit, there are turbulent waves.

The ancestor of their Gongyi family once said that they created a flying wooden bird.

Of course, this kind of thing.

It's hard for anyone to say, he's real.

It's still boasting.

At this moment, I heard Ying Changsheng say that it was really possible to create something that flew into the sky.

Gong Yi couldn't help muttering.

"Nineteen sons, and to put it in detail, if the old man talks about the skill of ingenuity, he is much stronger than the kid who made it, the old man and you ponder together, see if you can make it......"

"Good!"

Ying Changsheng thought about it for a while, it's okay to be idle, you might as well think about it with the public profit.

At this time, seeing that Ying Changsheng agreed, he hurriedly asked.

"What did the nineteenth prince say, flying into the sky? How did you make it to take the machine into the sky? ”

"It's easy!"

Ying Changsheng said.

Immediately, he said to the public on the side.

"Is there any paper?"

"What do you want paper for?"

If you look at the winning immortal, you ask.

"Something made for you that can fly into the sky!"

Ying Changsheng said.

Immediately, he said to the public in front of him.

"I can not only make machines fly into the sky, but I can also fly people into the sky!"

"Let people fly into the sky? Could it be that you put wings on it? ”

Gong Yi muttered incredulously.

And Win Changsheng couldn't help but roll his eyes, and then said to the father-in-law.

"Put wings on people, can you make people fly, people are different from birds, my method, you will understand later!"

At the same time, Gong lost to Pranya, but he had already taken some paper according to Win Changsheng's instructions, and Win Changsheng ordered her again.

I got some glue, some string, and a small piece of candle.

This made the public loser on the side look confused.

After all, this thing can be made, and it can make people go to heaven and be ingenious?

Just when they were wondering.

Ying Changsheng was busy, he used a knife to cut the paper.

Subsequently, a simple glue was used to make a Kong Ming lantern.

This thing, to make, is quite simple.

In the later generations, Ying Changsheng made several in the handicraft class of the elementary school.

The technology content is low.

It's not too low.

However, all this is in the current era.

But it seems so incredible.

After all, Kong Ming lantern is such a thing.

Although it is simple to make.

The principle is also very easy to understand.

But here's the point.

This thing was not invented by Zhuge Liang until the Three Kingdoms period more than 400 years later.

In the current era, no one would have thought that there would be such a thing.

What's more, it's only been a few days since the paper thing came out?

Who would have thought that paper would be used to make Kong Ming lanterns?

With the completion of the production of the Kong Ming lantern, Ying Changsheng placed the candle under the Kong Ming lantern and hung on the base with a thin rope.

Immediately, the candle was lit.

Then, carry it and make a Kong Ming lantern out of paper to prevent it from being lit by the candle.

When it was filled with hot air, Ying Changsheng slowly let go of his hand.

But I only saw that under the candle flame, the Kong Ming lantern slowly began to fly towards the sky little by little under the thrust of the heat generated.

In the blink of an eye, he had already flown more than ten meters high.

Looking at the public losses on the field, as well as the public losses, it is jaw-dropping.

"This, this is really flying?"

Gong Lose Prajna sighed.

The public on the side slapped his thigh.

"It's so easy!"

At this time, the public lost to the Buddha, but suddenly, a flash of inspiration flashed, and she walked towards the side to win the immortal road.

"Nineteen sons, if this lamp that flies into the sky is made bigger and stronger, can it fly to the sky with people?"

"Exactly!"

Win Changsheng couldn't help but nodded, and gave a thumbs up for the cleverness of the public on the side.

"That's true!"

Hearing this, he was slightly stunned, and instantly understood, he won the immortal way.

"It's just that if it's bigger, the materials used need to be carefully studied, otherwise, if you bring people to the sky, and then the material itself is not strong, or flammable, and it burns, it will kill people!"

"Indeed!"

Ying Changsheng nodded.

That's where the difficulty of making a hot air balloon lies!
