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

As the back garden and the witch dormitory are being expanded, the leaves have moved the plants to the vestibule. Various vines crawl over the walls, wooden frames and corridors, which look quite like a prehistoric forest, and the sunshade effect is also very obvious. The sunlight can only pass through the dense gaps between the green leaves, leaving scattered spots on the ground.

Roland gave the witches a stack of white paper, allowing them to spread it into a huge piece of painting paper, and then Soloya painted the lightest blue sky coating. Compared with the combination of cow intestinal skin and canvas used by the original hot air balloons, the pure coated fabric is much lighter and has excellent toughness. There is no suture at the connection, and no matter how big it is, you will not be afraid of disintegration in the air.

"Listen to the Lightning, there may be witches coming over the fjord?" Wendy asked curiously.

"If everything goes well," Roland said the content of the reply from the Five Kings, "the specific situation will have to wait for Tilly Wimbledon's reply."

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

"Yes, I'm afraid Tilly has been planning this migration for more than a year or two," Roland said, "not only Gray Castle, but also the other three kingdoms have sent witches to secretly contact them. The Co-Assistance Association should have received her invitation. I guess this is why the personal guards spread rumors for so long, but the witch has not come to him for a long time. After all, it is one step slower than Tilly."

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

"If she tells you Tilly's invitation, maybe you won't insist on finding the Holy Mountain anymore, right?"

"It's true that this is possible, but in this way, we won't meet in the border town," she smiled and shook her head, "so... it's not bad."

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

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

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

"Yes, some people are like this. Although Ash refused to do it last time when he invited it, he pretended to behave," Miyue muttered, "and said he was not a traitor!"

"You..." Lily widened her eyes, "Idiot!"

"traitor!"

The other witches couldn't help laughing.

"I feel the same way," Roland felt a sense of accomplishment suddenly surged in his heart. Even if he could not be as smart and agile as the Five Kings, he was not as strong and decisive as Tifeco and Garcia. But at least, he could give these witches a free and comfortable living environment and bring a better life to the people under his rule.

"This hot air balloon...is probably several times larger than the last time," Nightingale looked at the part that had been drawn by Soloya, "Are you going to use it to transport the witch?"

He nodded, "Only in this way can we avoid the harbor city and go directly to the territory 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 both sides, it becomes a mezzanine fabric. Each piece is nearly six meters long and wide. If it is a conventional canvas or linen, it is difficult to drag with one hand. However, for a light coating, it is almost the same as the weight of a stack of paper. Splicing more than a dozen pieces of fabric together and bonding the seams by the coating, it creates an amazingly large airbag.

What Roland wanted to test was the bonding ability of Soloya's coating. At least when he saw her new ability at the beginning, the "thick bark" painted on the table was fresh in his memory. The two were firmly bonded together, holding the bark and pulling upwards, and even lifting the entire square table. How closely the paint can be with the base layer, whether it can support a huge airbag and maintain its firmness and airtightness after inflating, is all he wants to know.

Hot air balloons still need to be inflated by Anna, while hydrogen balloons can be controlled by anyone. Nowadays, there is a DC motor that can produce hydrogen by electrolyzing water. The famous Zeppelin in history seems not far away from him. As long as you find a suitable lightweight skeleton-making material, this huge monster that can fly at an altitude of two or three thousand meters has almost no natural enemies, and the technical difficulty is much lower than that of an aircraft.

Although the hit rate of bombs dropped at a height of 1,000 meters is very touching, but the enemy cannot resist the attack and can only be beaten and cannot fight back. Swipe around the enemy's territory every day, and I am afraid that any opponent will collapse.

Imagine that when you go to the Holy City of the Church in the future, four or five airships will be floating side by side in the air, bombs will fall like raindrops, shallow water heavy artillery boats will bombard the opponent's city gates and strongholds in the river, and infantry holding continuous fire guns are waiting in the rear, and the three armies of navy, army and air combat in three-dimensional coordinated manner will be a little excited just by imagination.

"Your Highness, why are you giggling again?" Anna sighed and reached out to cover the corner of his mouth that could not help but open.

"It's probably because I'm thinking about those new witches," Lily rolled her eyes, "A man..."

When the huge vine hanging basket was connected with a hemp rope under the airbag, the new generation of hot air balloons was completed. The volume was nearly four times larger than the first generation, and the membership was also expanded to ten people. There was also a sunshade above the hanging basket to avoid direct sunlight. Of course, a hole should be left on the shed for Anna to replenish the balloons.

Roland named the balloon the Yaowang, and after completing the heavy load test on the open space in the park, he officially conducted his first voyage the next day. In addition to the five witches including Anna and Wendy, the prince himself was also involved.

The entire voyage was very smooth, and the witches kept chirping in the air, lamenting that the spectacular scenery seen from the sky from the bird's eye view was obviously more interesting than the fixed-point observation last time. The Aowang advanced south under the steady wind of Wendy, arrived at the mountainous area at noon, and crossed the top of the mountain with a flag, and finally hovered above the coastline.

After flying around the shallows, the group returned to the castle with the Far-Watch. Roland noticed that Wendy, who was in charge of direction control, was often beaten on his shoulders, and looked very tired.
