There was a cacophony throughout the auction room, and everyone was quietly discussing what the drawing was.

Hot air balloons and airships are not uncommon, and although it is said that the kingdom of the Bit people has the most complete manufacturing methods, many people have actually seen that these air transports do not have a high technical content.

Moreover, their shortcomings are also obvious, that is, it is difficult to control speed and direction, and the defense is low, so although these transports have been around for a long time, they have not caused a boom.

In the high air, the danger is much higher than on the ground, and once you are targeted by a fierce flying monster, the consequences are unimaginable, so most people prefer to walk on the ground.

As for what this wind-powered airboat is, few people present really don't know.

An Xu also asked Knoll the question in his heart: "Is there any difference between this wind-powered airboat and a hot air balloon?" ”

"The difference is big, if you use the ship at sea to describe it, the hot air balloon can only be regarded as a small sampan that drifts with the current, and the wind-powered airboat is a real super ship, which contains the technology of converting the wind element into driving force, which can send heavy vehicles into the sky, have you ever imagined it, a big ship that can fly freely in the air, covered with thick iron armor, and even you can place heavy attack equipment on the ship!" Knoll replied quickly.

"Really? Such a technical drawing, the reserve price is only 200 gold coins? An Xuhu doubted, if it was really as Noel said, such an air warship could be built, let alone 200 gold coins, and 20,000 gold coins were rushed to ask for it.

Even the royal family would not allow such technology to flow into the people, as long as the manufacturing method was mastered, a country could use its vast resources to create an invincible air fleet.

"Of course it's true!" "But that drawing is certainly not complete, and if you don't have a solid foundation in this area, getting a drawing like this will do little to nothing," Knoll explained. But we are different, there are a lot of flying vehicle technologies left in the kingdom of bits, as long as you get this drawing, you can further improve them, not to mention that you can definitely build a wind-powered airboat, but at least you can modify a great flying tool. ”

An Xu was a little moved, the air battleship described by Noll was too powerful, if the future team could really have a large vehicle with aerial firepower, and even provide an entire team to ride, it would not be too good.

The people in the room were still talking about it, most of them just joining in the fun, and those who really understood the usefulness of this drawing were considering whether it would be worth paying a lot of money to buy it.

After all, the wind-powered airboat only exists in legends, whether it exists or not, no one has seen it, and looking at this small drawing, the technology that can be contained in it is extremely limited.

Of course, there are also people who are obsessed with engineering, and after thinking about it, they start to bid, they have the same idea as Noor, even if they can't build a wind-powered airboat, it's good to peek a little bit of information to make their technology more sophisticated.

"320 gold coins!"

"340 gold coins!"

……

"410 gold coins!"

The price slowly climbed, and it didn't take long for it to reach the amount of 500 gold coins, and by this time, there were fewer and fewer people participating in the bidding.

The study of a technology is often a bottomless pit, these hundreds of gold coins are invested in it, just to obtain some scattered technology, if you want to further research, you will inevitably encounter all kinds of problems in the future, will cost more money.

Even if it is a large family, it may not be able to afford it, not to mention that this technology is likely to fail in research.

The pressure on Knorr also increased, although Doudou and Fanny would definitely support themselves, but this amount of gold was almost beyond their preparation.

At this time, An Xu finally spoke: "Buy it, I'll help you out if it's not enough!" ”

At the point where they are at the point of being able to get to the point, money is no longer their only pursuit, what they need is to break their shackles and continue to climb to the top of a higher mountain, and now, it is a good opportunity.

Even if the research fails, at most some money will be lost, and some failures must be tried if you want to be different, and if Noll can get a little useful technology from it, it will be worth the investment.

With An Xu's permission, Noor's confidence instantly became sufficient, and he once again shouted a dumbfounded price.

"700 gold coins!"

Most people think that the people in Wing 5 must be crazy, and take out 700 gold coins to buy a broken drawing, isn't it crazy? Either there's really too much money to spend, and the random price is just to show your identity.

But since Noll was in the VIP room, no one thought he was joking.

Knoll was not bidding indiscriminately, he observed for a while, there were several bidders who were still hesitating, at this time, directly increasing a larger amount, showing his determination to win, can make most people retreat, but it is easier to win this drawing.

And, Knoll is truly imperative!

Those so-called engineering enthusiasts do not understand the value of such drawings at all, and only the bit people know how important such drawings are.

Technology is priceless, if Nuoer has 10,000 gold coins, it is estimated that he will not hesitate to call 10,000 directly.

If he brought this blueprint back to the kingdom of Bit, the elders who had been busy studying engineering all day long would buy it even if they were to sell iron, and with the blueprint they found last time in the ruins, they would probably make something that would make the world tremble.

An Xu behaved calmly, since he had promised Noll, he naturally couldn't go back, and he was also quite curious about why this drawing made Noll so fascinated.

"700 gold coins, the guests in the fifth room gave the price of 700 gold coins, this is a drawing with a lot of technology, even in the auction rarely appears, miss this opportunity, there is no room for regret!"

Ouyang Qingxue raised the hammer in her hand and said loudly, to be honest, she was also surprised that this drawing could reach such a high price, adhering to the basic principles of the auctioneer, she still continued to set off the atmosphere of the scene.

"720 gold coins!" After a few seconds, an old voice sounded in a side room opposite, and it seemed that the other party had been hesitating for a long time about this price.

"800 gold coins!" Knoll didn't hesitate to bid again.

"Hey!" The man in the chamber let out a slight sigh, clearly giving up.

"800 gold coins once, 800 gold coins twice, 800 gold coins three times! Boom! Congratulations to the guests of Room 5, you have won the items in this auction! Ouyang Qingxue saw that no one was bidding anymore, and finally knocked down the hammer in his hand.

"Yay, that's great!" An Xin clapped her hands and said, she didn't understand the difference between 8 gold coins and 800 gold coins at all, but she knew that Noel had won the auction, so she was very happy.

The staff knocked on the door of the wing room again, this is the third item photographed in the No. 5 wing, and even many people on the field are secretly asking which big force is in the No. 5 wing.

After getting the drawings, An Xu poked his head curiously, wanting to see what the drawings worth of 800 gold coins were.

It's a pity that it is full of some difficult graphics and numbers, which makes An Xu confused.

"That's it, that's it, the conversion technology of the wind power source, although it is incomplete, but give me a little time, I will definitely be able to master it!" Knoll only took a cursory glance and was sure that this was exactly what he needed.

An Xu also breathed a sigh of relief, it seems that these 800 gold coins will not be spent in vain, although some things cannot be measured by money, but such a large sum of money makes him a little frightened.

"Help me collect it first, and then give it to me when I go back!" Noll handed over the drawings to An Xu and asked him to put them in the space ring, he didn't know that An Xu's space ring had been handed over, and he was currently using the storage space for the badge.

This drawing is too important, and Noll is afraid that he will accidentally lose it, so he will want to cry without tears.

An Xu put away the drawings and just heard Ouyang Qingxue start the auction of the next item.

"Ah, there are a lot of good things today, the mages present this time are blessed, the quality and size are perfect water spirit crystals, presumably the mages have understood its function, inlaid on the staff, you can make your own water spells be greatly enhanced, and it is also an extremely precious alchemy material, the reserve price starts at 800 gold coins——"

"Boom-" Countless mages in robes stood up in the hall in an instant.
