Jiang Feng didn't explain much to Kairut, but simply instructed him to prepare supplies for going to sea, as well as prepare a few comfortable rooms for him on the ship. After a while, they would make a trip back to the South Island, where they would make the final refits, and then when they would return to the port of Sevet, they would set sail with the horn as soon as they had loaded them with the supplies they needed to go to sea.

Time flies, and in the blink of an eye it is the end of the month.

For half a month, the iron-making blast furnace standing in the corner of the Samun tribe was running all day long, and the ore from the newly opened iron mine outside the river beach was smelted into molten iron, poured into a mold at the discharge port, and cast into a cannon barrel through a series of primitive forging processes.

As for the wooden gun carriage under the barrel, because there was no technical content in the first place, Jiang Feng directly drew the dimensions and specifications of each part on the drawing, threw it to Du Wei, and outsourced it through the Craftsman Guild of Port Servit.

With the successful experience of the first artillery, the second and third guns were quickly machined and formed.

By the end of the month, the eight cannons had finally been fitted with modified brigs. In order to dispel Captain Kairut's concerns about this new weapon, Jiang Feng sent several sailors to row a small boat and throw a dozen empty wooden barrels with flags on the sea about two hundred meters away from the steamship.

Then, Jiang Feng ordered the sailors to push all the guns to the side of the ship, load, aim, and ignite according to the steps he said, and fired a salvo at the target not far away.

"Boom ——!!!"

With a loud bang that shook the heavens and the earth, the eight artillery pieces spewed out white smoke and retreated in unison. On the surface of the sea not far away, a series of water columns burst one after another. The sailor who was operating the cannon next to him was unprepared for a while, and was even so frightened that he sat on the ground, and was caught in his pants by the fire stick, and escaped with the help of the sailor next to him.

Although the eight cannonballs avoided all the barrels perfectly because of their lack of training, both the splashes that rose into the sky and the drops of water that fell on the tip of his nose perfectly told the captain the power of the previous round of artillery salvo.

After being silent for a long time, Captain Kairut swallowed hard and turned his stiff neck to look at Jiang Feng.

"It's ...... Witchcraft? ”

"Keep your eyes open and take a good look," Jiang Feng smiled, raised his chin slightly, gestured to Captain Kairut with his eyes, looked at the sailors on the side of the ship with frightened and shocked faces, and continued, "Do you think they look like wizard apprentices?" ”

Captain Kerut swallowed and spat, remembering the image of the cannon firing and the splash of the waves, and said to himself that even a wizard apprentice might not be that strong.

Just that round of artillery salvo just now, to say the least, it had to be a "boulder trampling" performed by a one-star wizard to barely achieve that effect. As for the "Boulder Trampling", which is a one-star sorcery, the objects of comparison are usually ballistas and trebuchets, and the power is naturally not stronger than that of better artillery.

Of course, if we talk about mobility, that's another topic.

Also stunned was Emily.

The little girl was also startled by the sound of the cannonball, but quickly recovered from the shock. The half-elf's powerful dynamic vision allowed her to clearly see the moment when the cannon was discharged. However, what she couldn't figure out was how it was just a thick and long iron pipe, and how it could shoot such a heavy buckshot.

"Good...... Terrible. Muttering to herself, Emily stared at the sea intently, and after a while, she suddenly looked at Jiang Feng next to her, reached out and pulled his sleeve, and asked with great interest, "Hey, how did you do it?" ”

Looking at those big eyes full of curiosity, Jiang Feng smiled, and didn't sell anything to her, and said as if chatting.

"Remember the last time I asked you to think?"

Emily nodded quickly, but quickly shook her head in frustration.

“…… Emily couldn't figure it out. ”

"Want to know the answer?"

"Uh-huh!" Those big eyes suddenly lit up, and Emily nodded vigorously, and said excitedly, "Can you really tell me?" ”

"This book is for you, so you can use it to pass the time when you are bored. Questions you don't understand, you can basically find them in it. I want you to enjoy the process of discovering the truth rather than having me tell you the standard answer directly. Jiang Feng took out a stack of printer paper bound in the shape of a book from his arms and handed it to Emily.

"But I can't read human writing......"

"It's okay, it's all half-elf language."

Emily was stunned and lowered her little head in embarrassment, and the red glow gradually climbed from her cheeks to the tips of her ears.

Holding the book "Science and Nature", the half-elf girl said thank you glutinously, turned around and ran back to the cabin. Not noticing the girl's strange appearance, Jiang Feng instructed Oliver and his apprentice blacksmith to show the sailors how to use a mop-like wooden stick to clean the cannon fodder from the cannon chamber and aim it with a caliper-like sight......

Back in her room, Emily closed the door, kicked off her shoes, and threw herself on the fluffy bed with the faint scent of the book.

The little face on the pillow was flushed, and the little hand quickly turned the page.

Looking at the delicate lines of text, as well as the accompanying pictures next to the words, Emily only felt warm in her heart.

"Hmph, although the person is very rude, the words are still quite neat......"

Muttering quietly, Emily flipped through the pages and watched absentmindedly.

However, it didn't take long for her to be deeply attracted to this never-before-seen world, and the speed of turning the book slowed down unconsciously.

Newton...... Mechanics? What is it? ”

……

Although she lives a carefree life, in fact, the loneliness in Emily's heart is only understood by herself. Her mother died shortly after giving birth to her, and her father was too busy with the affairs of the clan to spend time with her, and Emily, who couldn't play with the other half-elf children, usually played alone.

Emily, who had no concept of such a thing as "printing", thought that Jiang Feng had taken time out of his busy schedule for herself, and wrote this book for herself in the language of a half-elf. Although Jiang Feng always knocked on her forehead, at this moment, her heart was as sweet as eating honey.

That face doesn't seem to be so annoying anymore.

If Jiang Feng knew that his behavior had caused such a big misunderstanding, he would definitely explain to Emily in a serious manner that this book could only be regarded as a common enlightenment book in the Federation, mainly used to cultivate children's interest in natural science, establish basic materialist values, and so on.

Because it is an enlightenment book, the text is not too boring, and it pays more attention to the process of exploring the principles than instilling dogma, so even children can read it with relish.

Basically the vast majority of Union citizens have read similar books at a very young age, with the only difference being that they may read slightly different versions. Jiang Feng just pieced together the fragments of the book he read when he was a child, through the deep memory retrieval function of the brain, and then printed out a copy.

He hadn't thought about raising Emily to be the founder of modern physics half-elf or anything, but he just planned to find something meaningful for her energetic to do, so that she could settle down a little and not get into trouble all day long.

Of course, if she really had the talent in this area, Jiang Feng would also be happy to see her embark on this path.
