"Your Highness, when I entered the door I wanted to ask you," said Hogg, showing a look that had finally slowed down, and a pot of ice in the barrel had been drunk by him, "the painting in the hall... I am afraid that it can't be painted by ordinary people?"Whether it is realistic or from the perspective of the view of the earth from the air.”He paused and lowered his voice, “Is this... the work of a witch?”

Roland looked at Margery, who nodded, "Your Highness, rest assured that Hogg was an old friend of mine for many years, and that he had no ill-will to the witches."

"You're right, it was a witch."After a hot air balloon ride near the beach two days ago, Roland wanted to preserve the magnificent beauty of the scene, plus the castle living room was poorly decorated, and there was no hanging painting, he simply let Soroia turn the stone wall behind the main seat into a huge mural.After the artistic background wall, the style of the hall was instantly upgraded several grades.

“I knew,” Hogg sighed, “that although they were advertised as the minions of the devil, their strange abilities were enviable.”Ordinary people can't fly into the air like they do and paint a mural so beautifully."

"You're right," Roland said, shaking his head, "that ordinary people can fly even higher than eagles, even if they don't rely on magic, and fly faster than the Swift."

"You're really humorous," laughed Hogg, "and unless we have more wings, we'll be lighter than the birds."

Marguery was stupored, “Really?”

"Certainly," laughed the prince, "I can prove it to you."

To show the merchant his inventions is also an effective way to enhance relations and expand the way of trade—from the mug to the liquor, and to selling it or not to sell it is another matter.Anyway, the caravan will stay in the town for a few days, and the regular business negotiation process should be to eat, drink and play and finally sign.And Anna is also very interested in traveling in hot air balloons, just allowing her to take a break from her busy work and take a break.

The remote was quickly completed inflatable, this time Roland simply called the witch who could not ride in the hot air balloon, Lucia also asked if she could take his sister up to see it, and he also promised to come down.

As the balloon slowly rose with the crowd, Marguerite covered her mouth in surprise, while Hogg clutched the edge of the basket, not knowing whether it was agitation or fear.The bell was too short to see the scenery outside the hanging basket, Lucia had to pick her up, ride on her shoulder, carefully approach the edge of the basket, and told her not to move.Lightning as navigators and rescuers hovered around the hot air balloon, occasionally showing his face to the bell.

In this way, the hot air balloon once again dangling around the southern coastline and completed the air sightseeing tour.

...

When he returned to the castle, Hogg's legs were still trembling, and he stammered, "I never thought that looking down in the sky was so terrible that I felt as if I could fall at any moment."

"It's good to fly a few more times," Roland laughed, "for the first time anyone who leaves the ground with both feet will have the illusion that he will spit on a bumpy ship."

"You speak a little well," marveled Margery; "the view you see today is incredible, and looking out of the air to the edge of the sea is like a blue arc."

"But, my lord, I am not wrong," said Hogg, taking a sip of the cold white wine, "and the common man has indeed flown into the sky, but it is still the merit of the witch."Without them, this big guy wouldn't be able to fly."

"No, my old friend," said Marguerite, before Roland spoke, "didn't you find out?"Miss Anna was just releasing the flame.I also specifically asked about the lightning, and she told me that as long as I put the heat in the airbag, the teleportation could go up to the sky on its own.Flames are not the prerogative of witches, Your Highness, am I right?”

It is true that in the king's foothold fjord sea merchants, whether it is observation or thinking ability are particularly outstanding, Roland smiled and nodded, "hot rise, cold air sinking, this is why it is called hot air balloon."

“Do you really just need a fire?”Hogg is doubtful.

“That can’t be done, because in order for it to float in the air, it has to be heated continuously, and the wood itself is heavy, it can’t carry too much, and it has to be solved in a special way.”

“Can you do it?”Marguery couldn’t wait to ask.

"Well... it should be," Roland thought for a moment, "it's just a little trouble."

"That's great," she answered immediately, "I wish I could buy four or five hot air balloons from you, not too big, just one person."

“Do you want to use it on the ship?”Hogg asked.

"Well, the mast can't be stretched infinitely, but the hot air balloon can, as long as the rope is bolted under the hanging basket, so that it does not float with the wind."With hot air balloons, watchmen can detect nearby pirate ships earlier, and for seafarers, in addition to unpredictable storms and tsunamis, the most harmful are hordes of pirates.”

"But it's probably not too low," Roland estimated in his heart, "I expect it will take more than a thousand golden dragons."

If you do not use the witch to heat, the hot air balloon must use gas fuel, the most easily obtained is undoubtedly gas.Unfortunately, the coal mine of the gray castle is in the cold wind ridge, too far away from the border town, according to the current traffic conditions, almost can not be transported.It is easier to replace with a hydrogen ball, but it also needs to solve the problem of the gas storage tank - if you can't charge it freely, there is no practical value.

“A thousand golden dragons per balloon, how about?”Margery countered, "If you do do this, I can guarantee that all the caravans who travel to and from the fjord want to buy one or two."

"This time the string moon bay caravan is not coming together, otherwise they will definitely have a large order," Hogg drank the liquor in his hand, "I don't have to, the hot air balloon, although it seems very magical, it is of no use to the mines in Silver City."I just want to get my steam engine as soon as possible."

The price offered by the other party made Roland overjoyed, and the thousand golden dragons were the premium after he increased the estimated price five times, and he did not expect the other party to accept twice the price of the steam engine.But consider it also that a ship carries more than that price, let alone a merchant fleet and sailors, as long as it can avoid the plundering of pirates, the deal is still a bargain for the sea merchants.

In addition, thousands of golden dragons are not a hammer sale, whether it is hydrogen or gas, are consumables, used up to get back to the town inflated, which is an additional income ... Of course, a large number of gas cans at a time, you can consider discount or give away the number of inflatables.At this point, the 4S shop and two barrels of oil were his example of learning and imitation.

Roland hesitated in a stupigned manner, and finally nodded, "Then deal."(Unfinished).
