The First National Preceptor of the Tang Dynasty

Chapter 591

Xu Tian was in class when he heard someone talking outside.

"The Second Prince has arrived."

Upon hearing that the Second Prince had arrived, Xu Tian quickly went out to greet him.

In fact, he had only met the second prince a few times.

He just felt that this prince, who looked so young but was full of a sense of justice, was quite appealing to him.

The second prince was overjoyed when he saw Xu Tian.

Xu Tian was about to bow when he was stopped by the Second Prince.

“Lord Xu, there’s no need for formalities. I just heard that you have added a science to your academy, and I was curious, so I came to take a look.”

The second prince spoke, but his eyes darted around.

Want to see what kind of science Xu Tian is doing?

We had never even heard of this name before.

However, Xu Tian incorporated it into his lessons, causing a great deal of discussion throughout the capital.

Xu Tian is now a household name across the country.

Everyone knows him.

Moreover, all the discussions about him were filled with curiosity.

Upon hearing that the Second Prince had come to see his performance, Xu Tian immediately laughed and said, "It's just an instinctive reaction that all things in the world make, so it's nothing special."

What he said was indeed true, but others might not see it that way.

The Second Prince asked directly, "I wonder how exactly Lord Xu's scientific approach works?"

The Second Prince had already heard about Xu Tian's performance in the main hall.

That's why we know that this so-called science is not like reading books.

Instead, we need to conduct experiments first.

However, even the Second Prince didn't seem to quite understand the meaning of this experiment.

Upon hearing the Second Prince's purpose, Xu Tian immediately said, "Since the Second Prince has come for this matter, that's perfect, since we're about to have this lesson. I'll give you a performance."

After saying that, he directly asked a student to bring the materials for today's science class.

"This is a raw egg and a hard-boiled egg. Today we're going to do an experiment: put both eggs in water at the same time, stir the water, and see if the eggs sink."

Upon hearing this, the second prince asked suspiciously, "Eggs are so heavy, won't they sink?"

Xu Tian simply smiled and didn't reply.

He then took two eggs and began to conduct the experiment.

As he said, one egg fell into the water, but the other egg miraculously floated on the surface.

"Can you tell which one is the raw egg and which one is the hard-boiled egg now?"

The students began to make various guesses.

Finally, Xu Tian brought out an item and smashed one of the eggs.

"As you can see, this is the hard-boiled egg, the one that sank into the water."

"However, this is not today's science lesson, but a demonstration for everyone. The egg that just floated up in my hand is actually a bad egg."

Everyone made a strange expression.

The second prince simply smiled.

Xu Tian then took a few small wooden sticks, made a human figure, and placed it on a bottle.

"Watch."

He said this to his students.

Then, the human body suddenly started spinning.

The steps seem very simple.

"This...this is amazing!"

The second prince was completely shocked.

He never imagined that such simple items, when put together, could produce such a magical effect.
