A crisp cry cut through the silence of the morning, and Rheins got out of bed groggily and went into the bathroom to let the cool water stimulate the chaotic mind. The elixir that removes the regurgitation of ice crystals inevitably brings some sleep-making side effects, so she had to go back to the station yesterday anyway to hibernate anyway, and only this place is the safest for her.

From the first floor, there was the sound of Ella talking to another person, and their voices were much lower than that of a bird that chirped from time to time. Reinse, who had recovered herself, walked down the stairs and, unsurprisingly, saw two red heads discussing something together.

"Good morning, Ella, Bora." Reins greeted them happily and held out her hand to pick up the green bird that flew over, "Has Bora's commission been completed?" What is the attitude of the owner of that house? ”

"Good morning." The siblings responded in unison, and Bora continued, "I just came back this morning. They were fine, his little one insisted on giving me candy, I checked that there was nothing wrong with it, and I got it back. ”

The bird sang happily and flew back to Bora's shoulder. There were a few toffees scattered around the table, and Reins walked over to pick one of them, peeled off the package and threw it into her mouth, then squinted a little with some enjoyment.

"This is a candy that the children of the big family love." She commented, "It's worthy of being a rich family, ask the mercenaries to teach them to tame the beasts, not to mention, and they can still get this kind of food." ”

Two months ago, the merchant had issued a commission to the Mercenary Guild in the hope that a mercenary would teach their children how to tame beasts - not for fighting, of course, but so that the pets could give simple instructions and learn to protect their little owners. Bora is an animal trainer who usually uses his flute to summon animals, but his favorite is his first contract beast, the emerald bird.

Few people know that Bora's talent for taming beasts is not something that can be learned through training alone, but those special reasons cannot be explained to others. So in the face of such commissions, Bora usually teaches the little masters to use some small means to make the animals obedient - in fact, just like the simplest ordinary animal trainers, reinforcing their behavior with rewards and punishments. If you really come across the kind of commission that wants her pet to fight, Bora will refuse outright. This is his unique skill, and it is natural that he can't teach it to others, right? …… Such reasons are generally accepted with understanding.

"I heard Ella say you're going to Morfi's base." Bora looked up at Rhine, ignoring Ella's protest of "calling sister", "When?" ”

"I'll arrive at the mercenary union at 10 o'clock, and I should be there in the afternoon." Reins waved her hand lazily, letting the gentle wind carry what she needed to carry in front of her, "I'll call you anytime if there's a situation, don't worry." ”

Bora nodded, not saying anything more. Maybe it's because my sister is too easy to worry, but my brother is colder. However, contrary to his temperament, he likes to wear some cute clothes very much, coupled with a neutral voice and long hair over the shoulder, which will make many people mistakenly think that he is a girl.

Ella pursed her lips in displeasure, telling her brother about this so that he could also persuade Rhine, but Bora had no effect at all. She could only resign herself to staying at home, waiting for the possibility of being summoned at any time...... And she didn't even know if she should pray that they wouldn't be called.

"Alright, Ella, I'm hungry, I need a full meal now and go deal with Morfi."

Reins dragged her chair away and sat down, and Ella rolled her eyes and walked into the kitchen. Reins placed her things on the table and tossed them into the bag she would carry when she went out—only when she was out meeting with someone other than the mercenary. While she was able to get what she needed whenever she needed by modifying her teleportation magic, it would cause panic among the people, especially since she was meeting the nobles of the family who were desperate for her life, who thought she could come up with something that could endanger their lives at any time.

Ah, though she does. She thought to herself wickedly. But her work ethic prevented her from doing so, and of course, the family wouldn't believe that she had a "work ethic".

Pack up some things for your life - yes, for your life. No matter what danger she encounters, a teleportation item that she can activate without using magic can get her back to safety. And in order to prevent accidents, she will install several different types. When Reins flipped through a necklace, she stared at it for a long time, and an indescribable premonition in her heart made her decide to stuff it into her bag.

After packing up the belongings she needed to bring, Ella brought out the food as well. Reinse's breakfast was usually made of milk and bread, because she didn't have the appetite for more substantial foods, such as meat or dishes.

"You say—" Reins broke the bread and slowly stuffed it into her mouth, "is it possible that I go to their alliance and run into the family that lost Leanne?" ”

Regarding the Molfi Family Alliance, it is known that it is made up of five large families. But not all of them know which five families they are - it is rumored that one of them has been wandering in the shadows, doing some shady work. Most of the time, the only people who communicate with the outside world are the families of the two leaders that the mercenaries met yesterday. Even the families may not know their full composition, let alone the mercenaries who are deliberately concealing the news.

However, in addition to these three families, she can also be sure that there is one family that is a member of Molfi. Reins thought as she bit her spoon. Therefore, there is only one uncertainty left. If she can meet all of them, then her luck is too good-

"Rhine." Ella's expression became intriguing, "Generally speaking, your sudden and unfounded speculation will become a reality. ”

Reins paused, and she slowly returned the spoon to the bowl.

"If it happens......," she gradually smiled, a fierce smile, "then I won't have to think about what to ask for." ”

Yes. She had always taught her Fili that if someone hurt herself, she had to pay it back with double it. Although Leanne is a fool who always makes people angry, since the other party is going to send it to the door herself, she will not let go of a good opportunity. It would be nice to be able to use this to laugh at Leanne.

Two hours later, in the mercenary guild, the white-haired man and the girl at the bar were glaring at each other, even though they had finalized how to sign an agreement - yes, the goddess girl and the tech-believing man could not use contracts or contracts, they were not binding enough on both parties at the same time, so they chose the way the agreement was given by the church - and the girl still didn't like to see the man of the family.

Yes, the girl doesn't possess any magical qualities, but she loves her guild, so she believes in the goddess just as much as the mercenaries. The apothecary taught the girl how to make potions for mischief, and the mercenaries taught her how to use small tricks that would be unnoticed, using them covertly and effectively.

Like yesterday's reckless behavior of Huck. As he rushed in front of him and sneered at Rheins, the girl slammed the table and sprinkled some small transparent powder on him. And when she had to remove the effects of these small powders, what she was really burning was another powder on the paper, allowing him to smell the powders to neutralize the previous effect.

This is also the lesson that the mercenaries have taught her, so that people will not know what methods she uses, so that others will not know the details of her, so that they will not dare to provoke her easily - even if someone will learn about the rule that the head of the mercenary guild is not allowed to have magical abilities, they will think that she has the favor of some magicians, and has certain props that ordinary people can use. This often leads those who have these thoughts to believe that she is being protected by a magician.

When Reins stepped into the mercenary union, she saw this big-eyed staring scene. Apaya just stood next to him, writing and drawing with a notebook. His frowning expression indicated that he was concentrating on his mechanical engineering. But Momo's cheers after seeing her shattered the scene.

"Lord Rhine!" Momo ran out from behind the bar, holding the agreement that Huck had given her that she hadn't signed yet, "Look, this is the agreement they brought over." ”

Reines took the agreement and looked at it carefully. It contains detailed information about the extent to which the union will be renovated, the time required for renovation, and the strength of the renovated union that will be jointly tested by both parties. At the end of the agreement, a copy of the exterior and construction drawings of the proposed union renovation were included. She glanced up at Huck, who had an even thicker teal under his nose than yesterday, and she wondered if he had used some method to cover his fatigue and make himself look refreshed. But the agreement seems to be quite sincere, and it doesn't use any tricks to make it a waste of paper by then.

"That's fine, Momo."

Rhines gave it back to the girl, who wrinkled her nose cutely. Huck had already walked up to them, and he waited patiently for the conversation to end, then he looked at Rhines cautiously.

"I think this agreement should have taken into account everything I could have taken into account." He struggled to choose the right wording, "There shouldn't be any loopholes in this, and I'm going to—"

His expression looked like he was biting his tongue, but he continued.

"It also added the clause 'even if Reins Fili can't save Hua Shao, this agreement will still work.'" His face tightened, "Do you agree to come to our base now?" ”

Reins nodded. She didn't continue to embarrass the other party, although it was indeed surprising that this article was added to the agreement, and the man didn't seem to be the type who would make himself suffer. But she didn't want to ask the question in detail, and Huck made it clear that this was not something he wanted to join. She let Huck walk in front, and Apaya, who put away the notebook, walked next to her.

"That one was added by Shao at the request of Hul." As if he didn't want Huck to stir things up when he heard this, he whispered, "I heard Miss Jura recount all the events of yesterday, and she thinks we should show more sincerity. And we shouldn't force you to promise that we will be able to heal her. ”

This sounds like the woman named Hua Shao is indeed quite smart. Reins thought. She knew that doing such a thing would make her fellow clans look like a disadvantage, but in reality, she had won the mercenaries' favor.

Yes, if they hadn't joined that and reversed themselves, Morfi's reputation among the mercenaries would have dropped again - after all, the agreement was only as a reward for Rhine's trip to the family base - and its members would have the potential to attract some of the mercenaries to attack when they were outside.

And now, assuming that Rhines really failed to save Hua Shao in the end, then because of her favor at the moment, her friendship with Apaya, and various factors, although she will not be good friends with Morfi, it will also make the mercenaries no longer take the initiative to embarrass them.

However, engineers certainly don't know what this represents. The Engineer generally just thinks that his best friend is very friendly and doesn't want to let the mercenaries suffer.

Reins glanced at Apaya, and the blond man looked at her inexplicably.

"Your family let you and Huck Wright come over?" She changed the subject, "They're not afraid that you'll fight?" Your relationship doesn't look so good. ”

And about this, Aphaya himself is not clear.

"I also don't understand that we don't like each other all the time." Apaya snorted, "He wants to play tricks on Shao's side, but Shao demands that he must personally hand over the agreement to the head of the union, Miss, and personally invite you to the base." And Shao asked me to come along, she thought that it was indeed too much for you to step into the family base, and I should relieve your pressure as your friend. ”

Hua Shao is really a very wise woman, and just by the few words said by the engineer, Reins can judge that the other party's reputation as "Molphy's brain" is absolutely worthy of the name. And with such a woman as a friend, Apaya is such an unsophisticated character, and I don't know if Apaya's stubbornness exceeds his attention to Hua Shao, or if he has become like this with Hua Shao's connivance.

Thinking of the latter possibility, Reins sneered in her heart, but she didn't let her thoughts show on her face.

The three of them had already walked out of the small town and stood at the entrance to a forest. The mercenary looked with interest at the small flying ship that was gradually emerging in front of him, probably only able to accommodate 3-5 people in addition to the operators.

"This feature should be your masterpiece?" She carefully observed the changes and shapes of the flying ship, "Although many machines at present claim to be able to achieve so-called 'invisibility', they only detect the destination they want to reach in advance, and then apply a protective layer of similar color to their equipment. The more upscale ones allow the operator to manually adjust the color of the display from inside the machine. ”

The three of them walked into the flying ship, and at the hearing of her words, Apaya inevitably raised a slight smug smile, but then calmed it down.

"Yes. I tried a way to use some kind of external gadget to detect the colors of the surrounding environment, and then feed back to the computing center to change the shape of the flying boat accordingly. He took out the notebook he had just put away, and quickly flipped through something, "But there will still be a loophole, assuming that the flying ship exists in an environment with different colors from every angle, the external device will cause too much computation due to the detection of too many colors, and the speed of the flying ship will be correspondingly slow. In addition, when you look at it from a certain angle, you will find that the color is completely wrong. ”

Reines raised an eyebrow, they had already walked into the main operation room, and they could see the huge screen in front of them and the control screens everywhere.

"I suppose you got your inspiration from the casting fire I spoke of earlier?" She smirked, and the other party held the notebook to her mouth, refusing to speak, "The flames can obtain the state of the metal being forged, and transform the scale and heat they need on their own......"

This kind of flame saves the armor casters the step and time of pulling the bellows to change the heat, but they still require the apprentices to watch the changes of the flames carefully, let the apprentices remember the changes in the flames and the changes in the metal, and then let them figure out the connection between them. However, armor forging masters prefer to master the fire themselves, and only when they want to forge a piece of equipment that is completely intolerant of errors, they will choose the "casting fire" in order to avoid environmental influences.

In fact, mercenaries and engineers alike found the flame to be a great fit for use in conjunction with the mass production of technology - the family's factories could now cast armor and weapons in batches, but they were not as easy to use as the armorsmiths made their own craft. The factory is not able to completely eliminate external interference, and the temperature is set according to the time, which can lead to the metal not reaching the optimal condition.

Apaya didn't think of making a similar device, such as adjusting the temperature by detecting the state of the metal. But their technology is not yet able to detect the inside of metal without touching or even cutting it, and it would still be a waste of time to ask armorcasters to make temporary adjustments to the metal's appearance in response to changes in its appearance. And the armorcasters were only able to feel the state of the metal more fully when they struck it with their hammers.

However, the stubbornness of the clans made them reluctant to buy the Forge Fire - they thought that the mages could easily do something about it - and the mages who could make the Forge Fire did not want to sell the convenience to the clan.

Rhine's gaze made it impossible for Apaya to remain silent any longer, and he put down his notebook with some indignation and threw himself on the chair.

"Yes, that's right, that's what I thought of when I heard you talk about the principle of casting fire." He opened his notebook again, and Reins found a chair next to him and sat down, "Although I haven't been able to make a device that can detect changes in the internal state of metal...... But if it's used for the concealment of a flying ship, I can still do it by simply discerning the surrounding colors. ”

Reins put one arm on the back of her chair and leaned on it, and she began to think about what he had just said, from her own perspective. If the mercenaries receive some special commissions, they also need to hide their whereabouts. And magic is not really that omnipotent, and magic will always bring some wonderful fluctuations in the air.

"Have you ever thought about ......," Rhines said slowly, narrowing her eyes, "the reason why the flying ship has a hidden function is to prevent others from seeing it, right?" ”

Apaya let her mind follow the mercenary's direction. Yes, whether it's a flying ship or whatever, the ultimate thing about having hidden functions is not wanting others to see them, and if they can choose a line that no one or a monitor can observe, then they don't need a hidden function-

For a moment, he seemed to catch something, but before he could react, the thought had already drained from his head again.

"You don't theoretically need to hide when no one sees you, and the reason why you choose to hide from the beginning is because you're not sure when you're going to run into a human or a monitor." Rhines continued to speak slowly, and Appaia felt that the right thought was already getting closer and closer to him, "What if......"

"Find a way to observe humans or monitors." Apaya and Leynes said the results at the same time, and Apaya's voice was slightly excited, and his inspiration just now was finally caught by him, "As long as we can observe humans and monitors, if it is in a multi-colored environment, then we only need to change the side of the flying ship that allows them to see!" For human observation, you only need to detect the vital signs and heat of the human body, and you don't even need to detect humans when the distance is too far, because it is difficult to observe the specific situation with the naked eye, and at that time, you only need to blur the color of the spacecraft. I'm going to need to collect some of the materials that are used for the monitoring equipment, and they're sure to use some common materials and procedures......"

Reins looked at Apaya, trapped in her own world, and when he came to his senses, she planned to laugh at him for the need for her own reminder to have a new way. Huck had been staring at them for a long time, and finally decided to let himself step out of the place.

A mercenary! I'm actually discussing technology with an engineer! The world is crazy!
