Zao Wou-Ki walked into the courtyard and frowned a little when he saw what his son was doing.

"Father!"

The son bowed,

Zao Wou-Ki nodded and said.

"Son, what are you doing here?"

Zao Wou-Ki pointed to the pendulum.

"Father, I'm doing a science experiment. ”

"Science?"

Zao Wou-Ki's brows furrowed even tighter.

"What is science, is it a powerful exercise?"

"Father, science is a secret hidden between heaven and earth, and people who don't understand it don't even know how many forms of water there are. ”

The son talked eloquently, a little excited, as if he had met a confidant.

When Zao Wou-Ki heard this, he immediately became interested.

In fact, the reason why Zao Wou-Ki wanted to come to the residence of the tenth princess was mainly because he heard some eunuchs in the palace say that she was doing something that seemed very strange to people.

For example, they were shocked to make a strange seesaw, with the fulcrum not in the middle, but in the third, and to put something that was twice the weight difference on both ends, and the result was able to maintain balance, which made them very shocked.

So, Zao Wou-Ki was curious, so he came over to check it out.

"Oh, isn't there only two forms of water: liquid and ice?"

"Stupid, stupid!"

The son suddenly sneered.

Zao Wou-Ki laughed, not caring, after all, his son was his favorite daughter.

"Then tell me, apart from these two, what other forms are there?"

"Gaseous, of course. When water is heated, water vapor is formed, and water vapor is the gaseous state of water, and there are many things that can be done with water vapor. ”

With that, the son took out a science book and pointed to it proudly.

Zao Wou-Ki looked at it, opened his mouth in surprise, and then took it and looked at it.

Ten minutes later.

"It's really a strange book, there is a machine in this world that can make it run on its own without adding true yuan power. Even the sky flies!"

For a while, Zao Wou-Ki was a little unacceptable, thinking that this was a bombastic book.

"Son, didn't you get deceived?"

Zao Wou-ki's face suddenly sank and said.

"Father, it's not. I followed what was written in the book, and I did some experiments myself, and found that it was exactly the same as what the book said. ”

The son was a little aggrieved.

Seeing this, Zao Wou-ki's face returned to normal.

"How can it be proven?"

"Father, please see! This is called a pendulum, and this is a very clear proof that the ground we are standing on is a sphere, a very large sphere. While revolving around the sun, it also rotates on its own. As long as the pendulum is swung back and forth, this pendulum will swing more and more at a different angle in the absence of wind. ”

With that, the son drew a long white line on the ground, and then used the white line as the trajectory of the pendulum and let go of his hand.

Fire Emperor Zao Wou-Ki watched with wide eyes, and as time passed, he really found that the trajectory of the pendulum had shifted, and the angle was getting bigger and bigger.

Seeing this, Zao Wou-Ki had basically believed what his son said, although he didn't know the truth very well.

"Alright, son, I already believe in you. But what's the use of you wasting your time doing these things?"

Zao Wou-Ki was a little unhappy.

"Father, science can also be used to make weapons. ”

"The book says that science can be used to create a powerful weapon, called the atomic bomb. ”

"A 50,000-ton atomic bomb can destroy everything within a five-kilometer radius in a matter of seconds. It's probably equivalent to the power of the infantile monk's self-detonation. ”

"If the equivalent is changed to one million, five million, ten million, or even ten million equivalent, I'm afraid half of the Fire Source Continent will be razed to the ground. ”

"Father, you said, the Mahayana period powerhouse blew himself up, can the power blow up half of the Fire Source Continent?"

A black line appeared on Zao Wou-ki's forehead because he was a powerhouse in the late Mahayana period.

"Still can't! But first we have to understand how the atomic bomb exploded? If it was like a monk who blew himself up, the 100 million-yield atomic bomb would certainly be more powerful than the self-detonation of a strong man in the Mahayana period. But don't forget, there are many places on the Fire Source Continent that have some formations to protect them. ”

"And, Father. Science can be used not only to make weapons, but also to improve the lives of mortals who have not cultivated. For example, we can breed food that can produce a lot of food, and machines that can do our own work. For example, this rice transplanter in the book. People sit on it, and machines can actually plant. ”

The son took out the agricultural book again and said.

Zao Wou-Ki took the book and was shocked when he saw the first page.

Soon, after reading a book, I picked up another one.

Half an hour later, Zao Wou-Ki's heart could not let go, and the things on the books made him unbelievable, and at the same time he was curious and questioned about the origin of these books.

"Son, where did you get these books?"

"Of course it was given to me by Sun Wukong. ”

Zao Wou-Ki's eyes narrowed, and he muttered to himself.

"Monkey King..."

In the hundreds of thousands of years since the birth of the Five Sources Continent, Zao Wou-Ki had never seen these, not even heard of them, and it was even more impossible overseas.

Suddenly, a bold guess popped into Zao Wou-Ki's mind.

Sun Wukong is from outside the mortal world!

As his mind opened, Zao Wou-Ki became more and more sure of his guesses.

And the main reason why Zao Wou-Ki has such a guess is the color pictures in the books.

It is inevitable that there will be some faces of Asian and Western men with short hair, and the main feature is short hair.

The Five Sources Continent is almost as old-fashioned as the ancient Chinese people's thinking.

The body is skinned, and it is received by its parents. But Yang Fan's changed appearance now is short hair, so the Fire Emperor Zao Wou-Ki feels that Yang Fan and the people in the book are the same place as the human race.

If Yang Fan was here, he would definitely give a thumbs up and praise Zao Wou-Ki's comments, he guessed correctly at all.

Thinking of this, Zao Wou-Ki smiled with relief. Suddenly, he actually discovered Yang Fan's big secret.

"Son, I allow you to study science, but I don't want your cultivation to grow slowly because of science. ”

"I remember, Father!"

The son bent down and ran over with a grin, and Zao Wou-Ki smiled helplessly.

At this time, in the Fire Source City Square, there were many monks walking around the teleportation array.

At this time, an uninvited guest came, it was Yang Fan.

Showing the token of his three-rank civil official, Yang Fan walked between the teams without hindrance.

Shenjian Gate is remote, close to Fengyuan City, and the nearest big city to it is called the capital, and the straight-line distance is also 3,000 kilometers. Although Fengyuan City also has a teleportation array, it does not go directly to Huoyuan City.

There are several small towns around the Divine Sword Gate, and some dangerous things in the town, those townspeople will hire the outer disciples of the Divine Sword Gate to do it, and give a certain reward, although it is not much. But this is what Jian Yi deliberately requested, and the purpose is still to temper and polish the arrogance of those people.

Soon, it only took half a day for Yang Fan to return to the Divine Sword Gate.
