Chapter 251

On the second day after Maggie left, Roland led the witches to start assembling a new generation of hot air balloons in the courtyard.

As the back garden and witches dormitory building are being expanded, Leaf has moved the plants into the front courtyard. All kinds of vines are covered with walls, wooden frames and corridors, which looks a bit like a prehistoric forest. The shading effect is also very obvious. The sunlight can only pass through the dense green leaves, leaving scattered spots on the ground. of light spots.

Roland gave the witches a stack of white paper, and asked them to spread it out into a huge drawing paper, and then Soraya drew the lightest blue sky coating. Compared with the combination of cow intestine skin and canvas used in the first generation of hot air balloons, the pure coated fabric is much lighter and has excellent toughness. There are no seams at the joints, and no matter how big it is, it is not afraid of disintegration in the air.

"Lightning said that there might be witches coming from the fjord?" Wendy asked curiously.

"If everything goes well," Roland repeated the content of the reply letter from the fifth princess, "the specific situation will have to wait for Tilly Wimbledon's reply."

"It seems that Ashes and the others have succeeded," she said thoughtfully, "so many witches have gathered on Sleeping Island."

"Yeah, I'm afraid Tilly has been planning this relocation for more than a year or two," Roland spread his hands, "Not only Graycastle, but also the other three kingdoms, she has sent witches to contact secretly, and the Freedom Society should have received her letter too. Invitation. I guess this is why the personal guards have been spreading rumors for so long, but no witch has come to her door—after all, she is one step behind Tilly."

"But Hakara never mentioned this to us," Wendy rubbed her shoulders.

"If she told you about Tilly's invitation, maybe you wouldn't insist on looking for the Holy Mountain anymore, would you?"

"It is indeed possible, but if this is the case, we won't meet in Border Town," she smiled and shook her head, "So... that's not bad."

"I think it's pretty good too," Lightning raised his hand.

"Tsk, maybe it's better to go to the fjords," Lily curled her lips. "After all, there are witches there, so you don't have to pay extra attention when you go out like in a small town."

"It's much better than before," Anna said seriously, "I didn't even dare to go out at that time."

"That's right, some people are like this, obviously Ashes refused the invitation last time, and put on a show," Mystery Moon muttered, "Also said that he is not a traitor!"

"You..." Lily's eyes widened, "Idiot!"

"traitor!"

The other witches couldn't help laughing out loud.

"I think so too," Roland felt a sense of accomplishment suddenly surged in his heart. Even if he was not as clever and agile as the fifth princess, he was not as strong and decisive as Timothy and Garcia, but at least he could Giving these witches a free and comfortable living environment can also bring a better life to the people under their rule.

"This hot air balloon...is probably several times bigger than the last one." Nightingale looked at the part that Soraya had already drawn, "Are you planning to use it to transport witches?"

He nodded, "Only in this way can we avoid the harbor city and go directly to the territory from the sea at the southern end of the town. Besides picking up and dropping off new visitors, it is also a new attempt."

After the paper is coated on both sides, it becomes a sandwich fabric, each piece is nearly six meters long and wide - if it is a regular canvas or linen, it is already difficult to drag it with one hand, but for a light coating, it is almost the same Stacks of paper are of equal weight. A dozen pieces of fabric are stitched together, and the seams are bonded by coating to create a giant airbag of amazing volume.

What Roland wanted to test was the adhesion ability of Soraya's coating. At least when he first saw her new ability, the half of the "thick tree bark" drawn on the table was still fresh in his memory. The two are firmly bonded together, grabbing the bark and pulling it up can even lift the entire square table. He wants to know how tightly the paint can adhere to the base layer, and whether it can support a huge air bag and maintain its firmness and airtightness after inflation.

Hot air balloons still need to rely on Anna to inflate, while hydrogen balloons can be manipulated by anyone. Now there is a DC motor that can produce hydrogen through electrolysis of water. The famous Zeppelin airship in history seems not far away from him. As long as you find suitable lightweight skeleton materials, this huge monster that can fly at an altitude of two to three kilometers has almost no natural enemies, and the technical difficulty is much lower than that of an airplane.

Although the hit rate of throwing bombs at a height of one thousand meters is very impressive, but the enemy can only be beaten and unable to fight back if he can't stand it - wandering around the enemy's territory every day, I am afraid that any opponent will collapse.

Imagine that when you go to the holy city of the church in the future, there will be four or five airships floating side by side in the air, bombs will rain down, and there will be shallow water heavy artillery ships bombarding the opponent's city gates and strongholds in the river, plus infantry with bursting guns The rear is waiting in full battle, and the three armed forces of the sea, land and air are fighting in a three-dimensional manner. Just imagining it makes me feel a little excited.

"Your Highness, what are you giggling about?" Anna sighed, reaching out her hand to cover the corner of his mouth that couldn't help grinning.

"Probably thinking about those new witches," Lily rolled her eyes, "Men..."

When the huge vine hanging basket is connected to the bottom of the airbag with hemp rope, the new generation of hot air balloon is completed. The volume is nearly four times larger than that of the first generation, and the number of members can be expanded to ten. There is also a sunshade above the hanging basket to avoid direct sunlight. Of course, there needs to be a hole in the shed for Anna to add heat to the balloon.

Roland named the balloon Yuanwang, and after completing the heavy load test in the open space of the garden area, the first voyage was officially carried out the next day. In addition to the five witches including Anna and Wendy, the crew members who participated in this test voyage also included the prince himself.

The whole sailing process was very smooth, and the witches were chattering in the air, lamenting the spectacular scenery seen from the bird's-eye view from the sky-compared with the fixed-point observation last time, this constantly moving sightseeing trip obviously aroused everyone's interest. The Lookout headed south under the steady wind of Wendy, reached the mountainous area at noon, passed the flag-studded mountain top, and finally hovered above the coastline.

After flying around the shallows, the group returned to the castle with the Watch. Roland noticed that Wendy, who was in charge of steering control, beat his shoulders from time to time, looking very tired.

He had heard that women with big breasts were prone to sore shoulders, and underwear appeared to solve this problem. Although he hadn't verified this statement, it was always right to try it. And as she grows older, Anna's body will gradually develop. Roland decided to make a small gift for each adult witch.
