Zao Wou-ki walked into the courtyard and frowned when he saw what Sizi was doing.

"Father!"

Sizi bowed,

Zao Wuji nodded and said.

"Sizi, what are you doing?"

Zao Wou-ki pointed to the pendulum.

"Father, I'm doing scientific experiments."

"science?"

Zao Wou-ki frowned even more.

"What is science? Is it a powerful technique?"

"Father, science is the secret hidden in the world. People who don't understand don't even understand the several forms of water."

Si Zi talked freely, a little excited, as if she had met a confidant.

When Zao Wou-ki heard this, he suddenly became interested.

In fact, the reason why Zao Wou-ki came to the tenth princess's residence was mainly because some eunuchs in the palace said that she was doing something very strange to people.

For example, Sizi made a weird seesaw. The fulcrum was not in the middle, but at one-third of it. They also took something twice the weight to put on both ends. The result was that they were able to maintain a balance, which shocked them.

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

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

"Fool, stupid out of reach!"

Si Zi suddenly mocked.

Zao Wou-ki laughed and didn't care, after all, Si Zi was his favorite daughter.

"Then tell me, besides these two, what other forms?"

"Of course it is gaseous. When water is heated, water vapor is formed. Water vapor is the gaseous state of water, and water vapor can also be used for many things."

After all, Si Zi took out a science book and pointed to a place in the book proudly.

Zao Wou-ki looked intently, opened his mouth in surprise, then took it and turned it over.

ten minutes later.

"It's a weird book. There are machines in this world that can run on their own without using real energy and adding water. There are even those flying in the sky!"

For a while, Zao Wou-ki was a little unacceptable, thinking that this was a boastful book.

"Sizi, could it be that you were deceived?"

Zao Wou-ki suddenly sank, said.

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

Sizi was a bit wronged.

When Zao Wou-ki saw this, his face returned to normal.

"How to prove?"

"Father, please look! This is called the pendulum. This can clearly prove that the ground we are standing on is a sphere, a very huge sphere. While revolving around the sun, it is still spinning. Just swing the pendulum back and forth, This pendulum will swing more and more deviated when there is no wind."

Having said that, Si Zi drew a long white line on the ground, and then took the white line as the straight line of the pendulum, and released his hand.

Fire Emperor Zao Wou-Ki opened his eyes and looked at it. As time went by, he really found that the pendulum's trajectory had shifted and the angle was getting bigger and bigger.

Seeing this, Zao Wou-ki had basically believed what Sizi said, although he didn't know the truth.

"Okay, Sizi, I already believe you. But what's the point of 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 an atomic bomb."

"An atomic bomb with the equivalent of 50,000 tons can destroy everything in a radius of five kilometers in a few seconds. It is probably equivalent to the power of a monk in the infant transition period."

"If the equivalent is changed to one million, five million, ten million, or even 100 million equivalent, I am afraid that half of the fire source continent will be razed to the ground."

"Father, you said, the strong of the Mahayana period exploded, can the power blast down half of the fire source continent?"

There was a black line on Zao Wou-ki's forehead, because he was a powerful late Mahayana.

"Still not! But you must first understand how the atomic bomb exploded? If it was like a monk blew up, the 100 million equivalent atomic bomb would of course explode more than the Mahayana strong. But don't forget, there are many fire sources on the continent. There are some formations to protect the place."

"Also, Father. Science can be used not only to make weapons, but also to improve the lives of mortals who have not cultivated. For example, they can cultivate food with a lot of output, and machinery that can do their own work. Just like books. Get on this rice transplanter. People sitting on it, the machine can actually plant."

Si Zi took out agricultural books again, 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 couldn't let go of his heart. One thing in the book made him hard to believe, and he was curious and questioning the origin of these books.

"Sizi, where did you get these books?"

"Of course Sun Wukong gave it to me."

Zao Wou-ki narrowed his eyes and muttered to himself.

"Sun Wukong..."

Zhongguan Wuyuan Continent was born for hundreds of thousands of years, and Zao Wou-ki had never seen these before, and he hadn't even listened to it, even more impossible overseas.

Suddenly, a bold guess burst into Zao Wou-ki's mind.

Monkey King comes from outside the ordinary world!

As his thoughts opened up, Zao Wou-ki became more and more certain of his guess.

The main reason why Zao Wou-ki had such a speculation was the color pictures in the books.

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

The thinking of Wuyuan Continent is similar to that of the ancient Chinese people.

Your skin and hair is from your parents. But Yang Fan's current appearance is short hair, so Fire Emperor Zao Wou-ki feels that Yang Fan and the person in the book are from the same place.

If Yang Fan was here, he would definitely give a thumbs up and give Zao Wou-ki a comment. He guessed it all right.

Thinking of this, Zao Wou-ki smiled relievedly. Suddenly let himself discover Yang Fan's big secret.

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

"I remember, my father!"

Sizi bent down and ran over with a smile, Zao Wou-ki smiled helplessly.

At this time, in the square of Huoyuan City, there were many monks walking around the teleportation array.

At this time, an unexpected guest arrived, it was Yang Fan.

Showing the token of his third rank civil officer, Yang Fan walked between the teams without hindrance.

The Divine Sword Gate is remote, close to Fengyuan City, and the nearest large city is called Jingcheng, which is also three thousand kilometers away in a straight line. Although Fengyuan City also has a teleportation array, it does not directly lead to Huoyuan City.

There are several small towns around the Divine Sword Gate. There are usually some dangerous things in the town. Those townspeople will hire Divine Sword Gate’s outer disciples to do it, and they will pay a certain amount, although not much. But this was what Jian Yi deliberately asked, and the purpose was still to temper and polish the arrogance of those people.

Soon, after only half a day, Yang Fan returned to the Excalibur Gate.
