The day after Maisie left, Roland took the witches in the courtyard to assemble a new generation of hot air balloons.

As the back garden and the witch dormitory building are being expanded, the leaves have moved the plants to the vestibular.All kinds of vines crawling with walls, wooden frames and corridors, look quite a bit of a prehistoric forest feeling, the shading effect is also very obvious, the sun can only pass through the dense green leaf gap, leaving scattered spots on the ground.

Roland gave the witches a stack of white paper, which they spread out into a huge piece of drawing paper, and then Soroya drew the lightest blue sky coating.Compared with the combination of bovine membranous skin and canvas used in the original hot air balloon, the pure coating fabric is much lighter, and the toughness is excellent, there is no stitching at the junction, and it is not afraid of air disintegration.

“Listen to the lightning, there may be witches coming over the fjord?”Wendy asked curiously.

“If all goes well,” Roland said again, “the details will have to wait for Tilly Wimbledon’s reply.”

"It seems that the ashes have succeeded," she said thoughtfully, "so many witches have gathered on the sleeping island."

"Yes, I'm afraid that it's been more than a year or two since Tiley has been planning this migration," Roland said, "not just the Grey Fort, but also the other three kingdoms, she has sent witches to contact secretly, and the co-examination should have received her invitation."I guess that's why the guards spread rumors so long, but the witch has been so late to come to the door - after all, it's a step slower than Tili."

“But Khakala never mentioned it to us,” Wendy rubbed his shoulders.

“If she tells you about Tilly’s invitation, maybe you won’t be looking for the Holy Mountain again?”

"It's possible, but then we won't meet in the border town," she said, shaking her head with a smile.

“I think it’s good too,” the lightning said by hand.

"Well, maybe it's better to go to the fjord," Lily skimmed, "after all, there are witches, and you don't have to pay special attention to it as if you were out of town."

"It's better than it used to be," said Anna earnestly, "and I didn't dare go out at that time."

"Yes, some people are like this, obviously Ashes last invitation also refused, but also pretended to be," Mystery Moon muttered, "and said he was not a traitor!"

“You...” Lily rolled her eyes, “stupid!”

“The traitor!”

The other witches couldn’t help but laugh.

"I feel the same way," Roland felt suddenly a full sense of accomplishment, even if he is not as smart as the five princesses, not as strong and decisive as Tifeco and Garcia, but at least he can give these witches a free and comfortable living environment, but also to the people under the rule of a better life.

"This hot air balloon...I'm afraid it's several times bigger than the last one," the Nightingale looked at the part that Soroa had already drawn, "are you going to use it to transport the witch?"

He nodded, “Only in this way can we avoid the harbor city and reach the country directly from the seaside at the southern end of the town.”And in addition to picking up new visitors, it is also a new attempt.”

After the paper is coated with two sides, it becomes a sandwich fabric, each piece is nearly six meters wide - if it is a regular canvas or linen, it is difficult to drag with one hand, but for a lightweight coating, it is almost equivalent to the weight of a stack of paper.A dozen pieces of fabric are stitched together, and then the coating is glued to the seam to make a huge airbag with an amazing volume.

Roland wanted to test the viscous ability of the Soro's coating.At least when I first saw her new abilities, the half-drawn “thick bark” on the table reminded him.The two are firmly bonded together, clutching the bark and pulling up can even lift the entire square table.How close the paint can be attached to the grass-roots, whether it can support a huge airbag and maintain its firmness and airtightness after inflating, which is what he wants to know.

Hot air balloons still need to rely on Anna to inflate, and hydrogen balls can be manipulated by anyone, and now there are DC motors that can be used to make hydrogen through electrolysis water, and the famous Zeppelin airship in history seems to be far away from him.As long as the right lightweight skeleton is found, the giant monster that can fly at an altitude of two or three kilometers has almost no natural enemies, and the technical difficulty is much lower than the aircraft.

Although the shooting rate of bombs dropped at an altitude of kilometer is very touching, but the enemy can not be beaten and unable to return - every day in the enemy territory around, I am afraid that any opponent will collapse.

Imagine that when you go out to the Holy City of the Church in the future, there are four or five airships suspended in the air, the bombs fall like rain, and there are shallow water heavy gunboats in the river to bombard each other's gates and strongholds, plus the infantry holding a continuous fire gun is waiting in the rear, and the three armies of the sea, land, land and air forces are working together in three dimensions, and it is only a little excitement.

“Your Majesty, what are you laughing at?”Anna sighed and reached out to cover the corner of his mouth that he could not help but open.

"Probably delusional about the new witches," Lily rolled her eyes, "man..."

When the huge vine hanging basket is connected with a hemp rope under the airbag, the new generation of hot air balloons is completed.The volume is nearly four times larger than the original, and the number of members is expanded to ten, and there is also a sunshade above the hanging basket to avoid direct sunlight.Of course, a hole needs to be set aside on the shed for Anna to replenish the balloon.

Roland named the balloon as the remote watch, and after completing heavy-duty tests in the open space of the courtyard park, the first voyage was officially carried out the next day.The crew involved in the test flight, in addition to Anna, Wendy and other five witches, but also the prince himself.

The whole voyage was very smooth, and the witches rattled in the air, lamenting the spectacular view from the aerial view - this moving sightseeing trip was obviously more interesting than the last fixed-point observation.The teleportus headed south under Wendy's smooth wind, reached the mountain belt at noon, crossed the flag-mountaintop, and finally hovered over the coastline.

After a round of flights near the shoal, a group of people returned to the castle with the Lookout.Roland noticed that Wendy, who was in charge of the direction control, occasionally thrashed her shoulder and looked very tired.

He had heard that the woman with a large chest was prone to shoulder soreness, and the underwear was to solve this trouble, although he did not verify this statement, but it was always right to try it.And as she grew older, Anna's body gradually developed, and Roland decided to make a small gift for each adult witch.(Unfinished).
