Now that they have seen it with their own eyes, everyone naturally wants to find out.

After Zeng Jian asked, others also pricked up their ears and listened curiously.

Zhu Houzhao was introducing to everyone in a mature and steady manner just now.

But when he heard Zeng Jian's question, he himself was a little dumbfounded.

How?

If not, just make a sphere, then light it on fire and inflate it.

It will fly up naturally!

How could he know if this gunpowder could be used?

Zhu Houzhao looked at Zhao Ce for help with a downcast face.

Zeng Jian also followed his gaze and looked at Zhao Ce eagerly.

Zhao Ce laughed and said: "Hot air balloons can take people into the sky, mainly by converting heat into buoyancy."

"Cold air sinks and hot air rises."

"This will naturally achieve the effect of manned launch."

Zhao Ce spoke in an understatement and the words were all very commonly used.

But after hearing this, a group of civil servants all looked confused.

"Oh...Is that so?"

Zhu Houzhao replied confusedly.

Zhao Ce looked at the confusion on everyone's faces and didn't know how to explain it.

Zhu Houzhao came back to his senses and said with admiration: "No wonder no one has been able to fly before. After all, it is such a profound truth..."

Zhao Ce smiled and said: "Actually, this principle is not too profound."

"If there are three books that can teach you roughly, even ordinary scholars can easily understand the principles."

"Is there such a book in the world?"

Everyone looked at Zhao Ce in surprise.

Zhao Ce laughed a little narrowly.

"Yes, there is."

"These three books are the Three Musketeers of Mathematics, Physics and Chemistry."

"Their names are Mathematics, Physics, and Chemistry."

"As long as you learn these three books, you can invite all kinds of gods and Buddhas, not to mention things like hot air balloons."

After the endless coma, Shi Yu suddenly stood up from the bed.

content.

He took a deep breath of fresh air, his chest trembling.

Confused, confused, and all kinds of emotions came to my mind.

Where is this?

Afterwards, Shi Yu subconsciously looked around and became even more confused.

A single dorm?

Even if he was successfully rescued, he should be in the ward now.

And my own body...how could I not have any injuries at all?

With doubts, Shi Yu's eyes quickly swept across the room, and finally his eyes rested on a mirror beside the bed.

The mirror showed his current appearance. He was about seventeen or eighteen years old, and he looked very handsome.

But the problem is, this is not him! Download the Star Reading app and read the latest chapters for free without ads.

My previous self was a handsome young man in his twenties who had been working for a while.

And now, no matter how you look at it, this appearance is that of a high school student...

This change left Shi Yu stunned for a long time.

Don't tell him that the operation was successful...

My body and appearance have all changed. This is not a matter of surgery or not, but magic.

He turned into a completely different person!

Could it be...that he traveled through time?

In addition to the mirror placed beside the bed, which was obviously not feng shui-friendly, Shi Yu also found three books next to it.

Shi Yu picked it up and took a look. The title of the book instantly silenced him.

"Essential Animal Breeding Manual for Beginner Breeders"

"Postpartum Care of Pet Pets"

"Evaluation Guide for Interracial Beast-Eared Girls"

Shi Yu:???

The names of the first two books are pretty normal, but what happened to the last one?

"cough."

Shi Yu looked solemnly and stretched out his hand, but his arm soon stiffened.

Just when he was about to open the third book and see what it was about, his brain suddenly felt a sharp pain, and a large number of memories came flooding back.

Icefield City.
