The lord's mansion in Cecil City is a silver-white metal ball with a diameter of one meter three and a pleasant and funny smiley face on the surface hitting the gate of the lord's mansion with no big or small force. Behind the metal ball, there is a metal box less than one meter long floating.

After two impacts, the door opened from the inside, and Betty, wearing a maid's skirt, appeared at the door. The little maid blinked her eyes and looked at the iron ball star outside the door, with a hint of surprise on her face: "Mr. Egg? Are you here?"

Although this iron-ball star rarely leaves her "mechanical throne", Betty is often pulled around various areas of the city by Rebecca. The most common ones she goes to are several factories and research facilities, so she naturally becomes familiar with the "Mr. Egg" in front of her.

"Lord?" A pleasant buzz came from the silver-white metal ball, "Or Miss Rebecca, I have something good for them!"

Betty blinked and reacted for a second: "The Lord and the Miss are not here. They are going to the Magic Technology Institute, but they should be back soon."

Nicholas' egg floated up and down and rolled up his body: "Okay, I'll do it later if I go in."

The strange-shaped "Mr. Egg" is a master of mechanical technology in the territory and a "person" that the lord values ​​very much. Betty still knows this, so she directly took Mr. Egg to the study on the second floor of the mansion as Gauwen had ordered before.

As the head of mechanical engineering in the territory, Nicholas Egg rarely leaves the Institute of Mechanical Research, let alone the industrial area in the eastern part of the city. However, this does not mean that he does not know what happened in the territory. After entering Gao Wen's study, he first saw the map of the South that was hung on the wall of the study, and noticed that in the upper half of the map, the location marked as the Rock Fortress, had been labeled with Cecil's logo.

"This way I can at least have a safe sleep," a low buzzing sound came from the metal ball. "So many shells were finally in vain."

The little maid Betty stood in a corner of the study, but she didn't understand the lord's war, and she was not interested in it. She just stood there quietly, looking like she was wandering around the sky, and didn't know what was thinking in her little mind.

Nicholas Egg waited in the study for a while, feeling a little bored, and couldn't help but talk to Betty: "Speaking of it, little girl, are you literate?"

Betty suddenly woke up from her state of wandering in the sky. She was stunned for a moment, and then nodded with a little uncertainty: "I know... although I didn't recognize it all."

After saying this, the little maid who was not very smart seemed to finally get into the state. After realizing that she had not yet entertained the guests, she quickly picked up her big teapot from the side and walked towards Nicholas eggs, while the latter was still saying to herself: "Oh, I know the words, just know it, then you usually see... Alas, what are you doing with the teapot?"

Nicholas Egg "looked" at Betty with a funny face (he really had no other expressions available), and then he saw the stupid little maid speak seriously: "Mr. Egg, are you going to have some black tea?"

Nicholas Egg was shocked in an instant: "...You haven't noticed that I have no mouth?!"

Betty seemed to have carefully looked at the structure of the iron ball star in front of him, and then turned around twice, as if looking for an opening that could pour tea into it. After finding that he really didn't find it, he elongated the voice "Huh": "Huh... I really don't!"

"Nonsense, I'm not unaware of this face being painted on my surface," Nicholas Egg shook her body and continued the topic just now, "Will you read the newspaper if you know literacy?"

"The newspaper... can be understood, and I can read it normally," Betty nodded, with a hint of happiness on his face. "The lord also gave me a set of stationery, with scissors and glue, and he taught me to cut out the content I like in the newspaper and make a book!"

After saying this, Betty wandered around Nicholas Egg again: "...Mr. Egg, you really can't drink tea."

Nicholas Egg couldn't understand why this little maid was so persistent in drinking tea for guests, but he was really worried that the dazed girl would have to drill a hole in her body and pour the tea in it, so he patiently explained: "I am different from you. I don't need to eat and drink water...or, my way of eating is different from yours..."

Betty finally stopped wandering, opened her eyes wide and looked at the metal ball in front of her with curiosity: "How does Mr. Egg usually eat?"

Nicholas Egg casually said, "Oh, usually it is absorbed by the body surface..."

As soon as he said this, he realized that the little maid next to him might have misunderstood, because the girl was shaking the big teapot in her hand while looking up and down at his round body, her face full of eagerness to try. Seeing this, he quickly spoke: "Hey, please take what you think in your mind and absorb the body surface that I said, and do not include asking you to water me!"

Betty suddenly showed a somewhat disappointed expression on her face: "…oh."

A ball of question mark appeared on Nicholas' egg: "Why are you so persistent in giving tea to guests?"

Betty showed her signature dull expression again, and after reacting for two seconds, she suddenly said: "Sister Ginny said that the most important thing for the maid responsible for receiving guests is to pour new tea for the guests in time..."

"Ginny..." Nicholas Egg recalled for a moment and found that she had never heard of this name. "Have you recruited a new maid in the Lord's Mansion?"

Betty shook her head whistled: "No, Sister Ginny was the maid in the castle before. She was responsible for entertaining guests and was the most powerful of us."

After saying that, she paused for a moment, as if she was recalling something, and then said: "Sometimes she would secretly bring the leftover snacks from customers to the kitchen and give them to us..."

"The castle before..." Nicholas Egg murmured in a low voice, understanding what was going on.

He found that Betty was in a low mood and realized that he had said something stupid before, which caused this stupid topic.

However, he did not know how to comfort an upright creature with too complex thinking and emotions, which really had too many difficult-to-understand characteristics, which were far less simple and easy to understand than metal and machinery. He could only learn from what he used to listen to humans often say to comfort each other, and said dryly: "Don't be sad, everything will be fine."

"I'm not sad, I'm getting better," Betty shook his head, as if he was already cheering up. "Ms. Vincent said that living is the happiest thing."

Nicholas Egg floated quietly beside Betty, realizing once again that humans are really a very complex and interesting creature.

And soon, the most complex and interesting people among all the humans he knew finally arrived.

Gao Wen pushed open the door of the study, and as soon as he entered the room, he saw Betty holding a teapot and the big metal ball standing next to Betty. He smiled: "Nicolas, I heard you brought me a 'good thing'?"

After Gao Wen followed, his head was poked out again, and Rebecca squeezed into the study: "I'm here, I'm here, Mr. Dan, what did you get out?! Car engines or bearings used on the boat?"

In the entire "Cecil R&D and Production System", the most closely related to the mechanical manufacturing institute of Nicholas eggs is the Magic Technology Institute managed by Rebecca. As the main R&D department of practical technology, the latter often entrusts some blueprints that have completed theoretical verification to the Institute for Mechanical Research. Such orders are usually more than the processing capacity of ordinary "bachelor of machinery" and are generally handled by Nicholas eggs themselves. Under normal circumstances, Nicholas eggs always hold several orders from Rebecca in their hands.

So when I heard that Nicholas Egg came to the Lord's Mansion with "good stuff", the person who was most excited was not Gao Wen, but Rebecca.

On the other hand, after saying hello to Nicholas Egg, he looked at Betty holding a teapot. When he saw the teapot in his hand, he couldn't help but smile: "Didn't you force our master craftsman to drink tea?"

"Mr. Egg has no mouth," Betty shook his head, "he can't drink."

"...you," Gao Wen shook his head helplessly, rubbed the girl's hair, "Go back and rest."

Betty left the room, and Egg Nicholas came to Rebecca and steadily placed the metal box that had always floated near him on the ground: "Those two things are almost done, but what I brought today is the finished product of another order,"

The lock on the metal box automatically opened, and the lid bounced up. One was about 80 cm long, and the rune interface could be seen at both ends. The metal roller device with subtle patterns in the surface was faintly silver-white.

A proud voice sounded from Nicholas's egg: "It's not easy to realize its functions. Although the principles and structural diagrams are very clear, it is not easy to master the appropriate ratio of Misin alloy. Even I have tested it for a long time before it can work stably. Miss Rebecca, please accept your order."

"This..." Rebecca looked at the metal roller in surprise, "You finally succeeded!?"

After seeing the shape of the metal roller, Gao Wen vaguely guessed what it was, but he turned to Rebecca for confirmation: "This is"

"This is the most important structure in the new printing press you mentioned before!" Rebecca smiled brightly. In order to design this thing, the Magic Technology Institute took a lot of effort. "I call it 'arcane transfer cylinder'. With this, what you requested is to make quick plates, easy editing, and continuous printing, and reusable printing. It is equivalent to making a reusable printing press."

"Article transfer cylinder?" Gao Wen didn't expect that Rebecca also learned his habit and created a new term for the student. He repeated the word and became curious about the metal cylinder in front of him. "Can you demonstrate it now? How does it work?"

"It also needs an input unit to work, but if you just want to see what it will look like after it starts, it's okay to inject magic into this part directly..." Rebecca said as she placed her hand on one end of the metal cylinder, "Be careful to inject some magic into it, and give the symbols for the test... Oh, Lord, why are you doing..."

Gao Wen pulled her hand aside without waiting for the girl to "inject magic": "I'll do it, don't blow up the house anymore."

After saying that, he no longer paid attention to Rebecca's sulking look, but under the guidance of Nicholas Egg, he placed his hand on one end of the metal device.

A little bit of magic was carefully injected into the metal cylinder.
Chapter completed!
