After finishing Dawn's affairs, Roland returned to his residence, a manor deep in the camp.
This place should have belonged to a wealthy businessman. Not only were there several connected two-story stone houses, but also a huge front courtyard and backyard. It's just that the turmoil in Hermes made the original owner disappear, and he took this place as a temporary place to stay.
Entering the main house in the middle, Anna was sitting at the table, carefully reading the books he found in the dream world. Sunlight poured from the window, casting her bangs a beautiful golden yellow, while leaving a light edge on the contours of her fair face.
"Is the meeting over?" She turned her head when she heard the sound, and asked with a smile.
"Well, everything that needs to be explained has been said. Nana and the others have to leave first tomorrow morning."
"Let's soak your feet first," Anna got up and brought a basin of water, put it on the low stool beside the bed, and then leaned over to help him take off his shoes and socks. The leather boots used on the plateau in this era are hard and airtight, so every time he returns to the bedroom, the first thing he does is soak his feet to relax, and then put on a pair of light soft-soled cloth shoes. At first, Roland insisted on coming by himself, but in the end he was unable to resist the stubbornness of the other party.
"How's the water temperature?" Anna sank the black fire into the water.
"A little more heat... ah, this is just right." Roland felt his feet surrounded by a burst of warmth, and couldn't help but let out a sigh of relief.
Not only that, the black fire will also turn into a ball, squeezing his instep and footboard like a massager, and finally covering the entire foot and drying the residual moisture.
It's so easy to get addicted to this kind of life.
"What about you?" Anna sat down beside him, "Will you go with Nana tomorrow?"
"No, the other person is Sylvie, her surveillance ability is irreplaceable for the garrison." Roland held the other's hand, "I can certainly stabilize people's hearts by going back, but they always want to I'm used to dealing with troubles without me. In addition, the main force of the first army is not in place, so I can only play a very limited role. After Maisie has transported the two of them, it will be my turn and the second batch. is you."
Since the ability of the hummingbird cannot take effect on living creatures, the number of people that Maisie can carry at a time is limited to about two people, and the fluctuation depends on the specific weight of the passengers. Lightning can also carry one person on its back, but the height will drop significantly. Basically, it can only fly close to the treetops. It is ok for emergency use. It is too unsafe for long-distance voyages.
It was a long journey from Hermes to Neverwinter, and even if Maisie was able to continue flying after the sun went down, and at the same time didn’t have to spend time every day foraging, it would take nearly three days one way. He can only deliver in batches according to the urgency of the witch.
Fortunately, the army will gradually advance southward along the inland river, and the interval between each batch of personnel will be shortened accordingly.
"It would be nice if there was a faster way of transportation," Anna raised her head, "such as a machine that can fly in the sky."
"That's not easy, unless" Roland wanted to say that without an internal combustion engine, it would be impossible to build a truly usable aircraft, but in the middle of the conversation, an idea suddenly flashed through his mind, causing him to change his mind subconsciously , "Wait, maybe it's not impossible."
"What should I do?" Anna's blue-blue eyes suddenly shone.
"Using the abilities of Wendy and Mystery Moon," Roland pondered, "If it's just for carrying people... the combination of the two might work!"
This is also the inspiration that Maisie's bombing plan brought him. If you don't pursue mass production or versatility, the witch's ability can be equivalent to a machine in many aspects.
After three years of accumulation, Neverwinter City now has lightweight aluminum materials, an arithmetic academy that can perform large-scale calculations, and a central carrier for verifying the results. An unpowered or weakly powered glider is not An unattainable goal.
Of course, the most important thing is Wendy's wind control technique and the electric motor loaded with Dawn No. 1.
In simple terms, an aircraft can fly because the engine provides backward thrust, which allows the wings to move forward into the wind, and uses the air pressure difference between the top and bottom of the wing to form a pressure difference, thereby gaining lift.
According to the existing technology in Neverwinter, the power of an electric motor is far from enough to pull up a plane, but he does not need to get lift from the movement. Wendy's wind is the "air pressure" that can act directly under the wings. Difference". The electric motor only needs to provide a horizontal component force, just as lightning adjusts the direction of a bomb in the air with a small force, and the plane can take off.
"In order to obtain efficient air-holding ability, its wings should be as long as possible," Roland recalled the appearance of later gliders, and became more and more excited, "but to maximize the lift before takeoff, it must have a wider wing. Gen, it can include all Wendy's wind control range. And... "
A properly designed glider can use thermals to climb heights, which greatly increases the gliding distance, but here, the witch can provide updrafts anytime and anywhere, which means that as long as the magic is not exhausted, it can fly forever.
In other words, as long as a runway is built at the destination, the aircraft can transport ten people or more at one time, even the slow glider, with a speed of more than 200 kilometers per hour, almost three times that of Maisie after she has changed into a fearful beast. , you can reach any city in Greycastle within a day.
Of course, whether it is prototyping or manipulation training, it is a step-by-step process. Even if they do it now, by the time they can go to the sky, the witch and the First Army will have already returned to Neverwinter City.
However, this idea still made the two discuss flying with great interest for a long time, and it has always been the biggest temptation for humans who were born on the ground and died on the ground. And the glider is different from the clumsy hydrogen balloon, the former is a real soaring in the wind.
If Edith can bring Roland a political surprise, then technically, the only one who can communicate with him on an equal basis is Anna.
"By the way," she carefully collected the discussion results and model sketches, "Have you heard any good news at today's meeting? You haven't felt so relaxed since you received the letter from Neverwinter."
"Forget it," Roland raised the corners of his mouth and briefly repeated the Northland Pearl's private meeting.
Anna couldn't help laughing when she heard Edith's reason.
"What's wrong?" he asked curiously.
"I want to say that she has a little too much confidence in everyone. Did you learn everything you taught? It's hard for advanced mathematics alone, not to mention physics and chemistry..." Anna grimaced, "I think even if it takes For a hundred years, I couldn't understand all those orange books."
"Pfft," Roland also laughed, "There are many more books like this in the dream world."
"Also, I don't think the future world will be what she said."
"Oh? Then what do you think it will be like?"
"She thinks that if you can't gain prestige through the two-sided offensive, it's better to let the morning sun fall into chaos, but I think the way to accumulate prestige is far more than this way. When you lead everyone to fight against the devil and wipe out all the terrible enemies who invaded the kingdom, this It is a prestige that no one can match." Anna said seriously, "You destroyed the church and won the battle of divine will, the witches will remember it in their hearts, and the Taquila remnants will be proud of you. You bring all kinds of knowledge to The public, as long as you open the book, you can always find your name. Whether it is history or the present, you will be known to everyone and everyone. Under such prestige, the lords of other kingdoms have asked to join in order to seek shelter. Under your rule, no one dares to go against your will because there have been too many examples to prove the fate of those who rebel. After a hundred years, there may be only one kingdom left in this world, and its border has already extended to the fertile soil Pingyuan, little by little, is restoring the glory of the human kingdom..." She paused, "Is this idea wrong?"
