Yarrow patted the piece of paper on the table and said softly, “Bevin, your mistake at the beginning was that you calculated the value too accurately.”

“Precise? Wouldn’t that be better?” Hurley looked curiously at the papyrus.

Yarrow explained patiently: “Hot air balloons are meant to take people flying. If the numerical value is too extreme, it is impossible to add weight sandbags to balance the overall center of gravity.”

“Because there is no balance of sandbags, it is impossible to adapt to people of different weights by adding or removing sandbags.”

“The second is air… that is, the wind, the density of which is different at different temperatures. You don’t know and have not considered this issue, and you calculated the results of the canvas very accurately, but you made a few references. Hot air balloons, all experiments in cool castles.”

“The difference between the temperature inside the castle and outside the castle is at least ten degrees. When the sun is shining, the difference may be even greater. How can such a big problem be ignored!”

“This is not an ordinary math problem. What is needed is not an ‘equal sign’, but a ‘greater than or equal sign’, leaving room for ups and downs.”

Yarrow looked at the boy beside him again: “You can calculate the limit value, but the new things you make can’t always pursue the limit. Every time you start, you have to leave room for trial and error. Because… create a new Things represent new, unknown dangers!”

Bevin calculates the required canvas volume. If you make a hot air balloon according to the calculation results on the straw paper, it is really called ‘there is no way out’.

The boy nodded obediently: “Okay, teacher, I understand.”

Little Heli looked back at Yarrow and asked curiously, “Air? My lord, isn’t the air just nothing?”

“Nothing?” Yarrow smiled and shook his head, “If there has always been a murloc who has never been out of water, and has never heard of the world outside the water, then to it, does ‘water’ mean nothing? No?”

“However, there are also bubbles in the water,” the little girl bit her fingers, her bright eyes filled with doubts.

“Yes, there are bubbles in the water,” Yarrow did not deny it, but turned to lower his head and asked, “Then please tell me the lovely little Hurley, what is in the bubbles that have nothing? If it is nothing, why? Water didn’t take up that part of the space? Instead, let those bubbles come to the surface?”

“Yeah, why doesn’t water occupy those spaces?” It was a very common situation, but after being circled by Yarrow, little Heli couldn’t understand why.

“There are three forms of matter, namely solid, liquid, and gas. For example, water, which is common to us, can be divided into three forms: ice, water, and water vapor. No matter which form, it cannot be said that it does not exist.”

After explaining the principle, Yarrow looked at the boy again, “Blisters are a common situation in daily life, right? A lot of knowledge is hidden in these common things. You must maintain your own curiosity in the future, and you can’t put anything It’s all a matter of habit.”

The teenager nodded heavily: “Teacher, I understand!”

Yarrow’s two students were young and didn’t notice the abnormality he explained several times.

Dylan, who had been raised as a housekeeper since childhood, was a genius. He couldn’t help asking, “Sir, are you… ready to leave?”

Little Heli’s expression changed greatly, “You want to leave?”

Yarrow rubbed the little girl’s red hair and reassured: “I can’t say leaving, I just have a little thing to do recently, so I won’t stay in the castle for too long recently.”

“For the materials I brought back, you can follow the purification and grinding methods I taught you before, and let those servants get the materials ready as soon as possible. I will come back every few days to get the finished product.”

Hearing that Yarrow didn’t want to leave directly, Xiao Heli was relieved and nodded her head: “Okay.”

“Deputy housekeeper.”

Dylan took a step forward, “Sir, you said.”

“Arrange the guards to burn a lot of charcoal, and then crush all the charcoal into ashes. Remember, the finer the better.”

Cutting down trees and burning fires is what the guards used to do.

Although Dylan didn’t understand what Yarrow was going to do, he nodded and said, “Understood.”

Yarrow looked left and right, and asked suspiciously, “By the way, what about Butler Bud?”

The deputy housekeeper explained: “In the past two days, the guards at the level next to him have all disappeared inexplicably. Old Bud is worried that other refugees will know the news, so he has been patrolling around recently and wants to block the news.”

It cannot be said that Bud’s approach is wrong. The refugees are inherently good or bad. If a large number of refugees flock here, it will naturally cause many related problems.

Yarrow came from the checkpoint. Having seen those chaotic scenes, he naturally understood this.

only……

“Why are there so many refugees recently?”

As Yarrow spoke, he turned his attention to the deputy butler.

The deputy housekeeper often goes to the towns in the territory to collect materials, and naturally he has a wide range of information.

The deputy housekeeper did not disappoint Yarrow either. He bowed slightly and said modestly: “It is rumored that there are many nobles on the front line to join the enemy, the defense line is already in danger, and no one knows how long it will last, maybe today, maybe tomorrow, It is not surprising to hear the news of the collapse of the defense line all of a sudden.”

Yarrow asked curiously, “Aren’t you afraid? Are there any bad rumors among the servants?”

“The cowardly died a few years ago, and those who are afraid will not stay in Perrin Manor, let alone come back here. My lord…this is our home, we are Klai The retainer of your knight,” the deputy butler smiled, his words did not waver in the slightest, and he seemed unusually calm.

When life and death become trivial matters, people who are alive either become more careful in order to continue living, or they don’t see life and death calmly and pursue their beliefs more firmly.

Although the deputy housekeeper seemed very calm about the past tragedy, Yarrow was an outsider after all, and it was not easy to intervene too much. He had to nod his head to show his understanding, and continued to explain: “Let Head Bud bring all the guards back, don’t worry about that for the time being. Wide things, just protect the surrounding area of ​​the castle.”

“If you think it’s really unsafe, you can put a guardrail around the castle.”

“Don’t block the news?” The deputy housekeeper was stunned and hurriedly persuaded, “Sir, once the news is not blocked, those refugees will definitely rush towards this side like crazy, and they will be like a violent torrent, confusing the entire territory. Incredible!”

Yarrow looked at the deputy housekeeper with a half-smile, “Aren’t you willing to let those disaster victims flood in?”

The disaster in the Perrin territory a few years ago happened very suddenly, so although the casualties were heavy, many of the wealth was hidden in the surrounding ruins.

Noticing Yarrow’s expression, the deputy butler also knew that he had seen through his own thoughts, so he could only muffled: “These are the wealth belonging to Baron Claire, and also the basis for rebuilding the territory.”

Everyone else in the earldom was thinking about how to get out, but the deputy butler was still thinking about how to build the Perrin territory.

Yarrow didn’t know whether to call him stupid or brave.

Everyone has their own thoughts, and Yarrow didn’t bother to worry about it. His tone was cold, and he ordered directly: “Give you two choices, or let Bud come back and let the victims pass through the surrounding open space.”

“Or I’ll let the victims go directly through Perrin Castle!”

“I have no right to manage Perrin’s territory, but you must also remember that I am still the owner of Perrin Castle!”

In the face of Yarrow’s strong oppression, Dylan’s deputy housekeeper had to bow his head: “I understand, I will notify old Bud immediately.”

Seeing that everyone else had arranged things, Bevin quickly said, “Teacher, what about me? What am I going to do?”

“You?” Yarrow looked at the boy, “The mistake has already been adjusted for you, how long will you be sure to make a hot air balloon that can take off?”

“As long as there are materials, I can do it right away, no more than a month at most!” Bevin is confident, the deconstruction of the hot air balloon is not complicated, not to mention that he has also made several small hot air balloons for data collection.

“One month?” Yarrow considered for a moment, then shook his head, “One month is too long.”

Yarrow made a decision: “Tomorrow, start it now, and at noon tomorrow at the latest, make a hot air balloon that can carry people into the sky, and then monitor the surroundings at all times to see if anyone insists on spying on the castle.”

Bevin’s face became bitter, “Tomorrow? It’s not enough time to cut and sew canvas!”

A single day is indeed not enough, but Yarrow has his own plans.

“I’ll cut the canvas for you, you go to prepare other equipment, and when I cut it, you just assemble it!”

“You?” Bevin raised his head in surprise, “Teacher, do you still cut?”

Yarrow didn’t say much, just nodded slightly, “To make alchemy items, your hands-on ability should not be too bad.”

“I’ll prepare scissors for you!” Dylan’s deputy housekeeper immediately galvanized.

“No,” Yarrow waved his hand to refuse, and then asked, “Is the canvas in the warehouse?”

Deputy Butler Dylan said quickly: “No, because you have already mentioned the need for canvas, so I put the canvas in the arsenal.”

“Okay, then you can go and do your own business, I’ll just go over by myself.”

…

Following Yarrow’s order, all the personnel took action, and the entire castle was very busy.

And Yarrow, as soon as he stepped into the arsenal, saw the folded canvas occupying half of the warehouse.

The space in the room was limited, so he opened the canvas inch by inch, and while finding out the shape of the sail, he calculated the length of one side.

– A triangle with a small corner missing!

The longest side is 47 meters.

Generally speaking, the length of the sail is not much different from the size of the sailboat. In other words, the canvas should have been hung on a sailboat of about a dozen or so.

Boats of this size are generally river boats.

Calculations show that the sail is really not big.

The sails on the boat he once sat on far exceeded this one, but the sails were hung on the boat at that time, and the visual impact was definitely not as good as it is now.

After calculating the size, Yarrow used a charcoal pen to draw the texture of the hot air balloon on the canvas, then picked up the fiery epee and activated the heat fusion technique.

As the blue smoke continued to rise, the pungent burnt smell filled the entire room, and Yarrow had to put on the scary-looking skull oxygen mask again.

Dissolving, cutting, punching, hot-melt bonding… Yarrow has done exceptionally coherent.

What Bevin might not be able to do well in half a month is so simple in his hands.

The main reason is that the canvas is too thick, and it is difficult to cut it with the scissors at this time. It is also because of this problem that it is very difficult to sew.

After all, hot air balloons have very high requirements for stitching, and the connection points must not leak air like other positions. This is a time-consuming thing. Bevin said that it takes a month, which is indeed reasonable.

Even if Yarrow has the help of thermal fusion, it is not an easy task to face such a large canvas.

The busy time passed very fast, and in the dim room, Yarrow had already used the light spell to illuminate.

I don’t know how long it has passed, and Bevin’s voice came from outside the room:

“Teacher…cough…teacher! Are you done? Take a rest, dinner is ready for you.”

After being busy for a long time, even if the doors and windows were all opened, the room was filled with a smoky smoke.

Yarrow’s eyes were also extremely stinging from the smoke. He blinked his swollen eyes and replied in a muffled voice: “No, I’ll finish it right away~www.mtlnovel.com~ Then…Teacher, there is still class today. ?”

Attend class?

Is it already eight o’clock in the evening?

Only then did Yarrow look up at the window. It was indeed a starlight. He looked at the last spot of the hot air balloon that was not ready, and turned back and replied: “Recently, you can just be busy with the things I explained. In addition, call Bud recently. Watch carefully, and don’t let any strangers near the castle recently!”

It may be because of self-knowledge that although Bud was arranged to be the supervisor, what he actually did was the captain of the guard.

“Okay teacher, I’ll go notify old Bud right away.”

As the hurried footsteps gradually faded, there was only Yarrow’s busy voice in the room.

When the hot air balloon was almost finished, Yarrow took out a few whole pieces of canvas that had been reserved before, and sewed them together again to form a whole triangular canvas again.

What he’s going to do this time is a glider — the deluxe kind.

The theme structure is made of an extraordinary material ‘fire steel’.

Well, this is the name he translated. It is said that it is a kind of ant’s shell, which is very light in texture and contains subtle void magic.

The texture is very light, but the hardness can be compared to ordinary steel, but it is very afraid of fire, the powder can be ignited by fire, and the price is not expensive. It is generally used as a special additive for alchemy materials, and some exotic types can also be used as fuel additives.

– For example, rich in pure fire or pure light.

Yarrow guessed that this thing may be aluminum. As for why the hardness is so strong, it may be related to the magic of the void.

This principle is the same as pure iron is very soft, but as long as iron contains 0.3% to 0.5% carbon, it is the same as hard medium carbon steel.
