"I don't deserve such a title. In the land of wizards, there are many wizards who are stronger and greater than me."

"Don't say that, Lord Linn. Your contributions in the entire history of magic are rare." Orlando flattered him quickly.

Lin En smiled and didn't reply. Compared to people like him who relied on scientific knowledge from his previous life to cheat, the founders of magical theories were truly great.

They are the ones who truly start from scratch and explore and expand the entire magical world.

"I have another question!" Cody said hesitantly. "This airship is so big, how can it avoid detection by the Vatican?"

If it is flying in the sky, it will be just a small dot. But once it lands, it will become very conspicuous and cannot be hidden.

"We have already considered this!" Philip laughed and gestured.

A wizard in charge of controlling the airship immediately activated the polarization magic.

Under the gaze of the crowd, the huge airship that was a hundred meters long in front of them slowly became illusory and soon disappeared from their sight.

Looking at the astonished and disbelieving expressions on Cody and the other boat workers' faces, Dennis and others, as the modifiers and designers of this aerospace airship, had smug looks on their faces.

They put in a lot of effort to push all the data to the limit.

Especially the invisible function, which racked their brains.

It is not an easy task to hide an entire airship. Ordinary polarization magic cannot do it. In order to enhance the power of the magic, they smeared the juice of the invisible beast on the surface of the airship.

This magical beast has a unique ability, which is that its skin can change color according to the external conditions, perfectly blending into the surrounding environment and hiding in the dark to attack prey.

However, the size of the airship is not small. They bought most of the invisible beast juice on the market to get enough for an airship.

"I named it the Invisible Sky Fortress!" Dennis said with great satisfaction.

Stealth hydrogen-powered strategic bombing airship? A series of terms flashed through Lin En's mind. He had heard that Dennis had found a solution to the problem of airships being large and easy to be discovered, but he didn't expect the solution to be so direct.

As long as you can't see it, it won't be exposed! I can only say... you are worthy of being the master of alchemy!

Lin En sighed secretly, and then asked someone to bring the goods for this trade.

The most important thing is naturally glassware...

After checking them out, Cody immediately discovered that most of these glassware had cavitations, which was an eyesore and completely different from the finished products he had seen on the market in Yieta.

"Dean, aren't these all defective products?" Cody asked in confusion.

"These defective products are necessary to reflect the value of the finished product, right?" Lynn said with a smile.

Since the workers in the glass workshop are all novices, they always produce a lot of defective products every time they cast. It is also a bit troublesome to melt them and recast them. There are just some cavitations inside, but they are not unusable.

For example, a set of glassware with cavitation bubbles could be sold for seven silver coins, while those without cavitation bubbles could be sold for ten times the price!

This way, they can make money from all walks of life, sell at high prices, and satisfy the feeling of superiority of some nobles.

Everyone is happy! He can also exchange a small amount of goods for a large amount of coins, and then exchange these coins for ore and transport them to Yieta Port, forming a virtuous circle.

All the wizards present were shocked by Lin's overly advanced economic ideas. It was also the first time that Cody knew about the trick of deliberately selling defective products.

However, this is only possible for monopoly items like glass products.

"By the way, the cabin of the airship can only carry 25 people at a time, and it also needs someone to drive the airship and be responsible for subsequent maintenance. Before tomorrow, you can select 15 representatives to be responsible for transporting this batch of goods." Lin En reminded.

There are only fifteen places... Cody immediately became a little hesitant. There were a total of 150 people coming to transport this batch of goods. Who should stay and who should go back is a question worth pondering.

Lynn patted Cody on the shoulder and asked him to think slowly and get familiar with the airship. He then returned to the dean's office and called Lord over.

"Lord Lin En!" After nearly four months, Lord was summoned by Lin En again. He immediately bowed deeply to Lin En, prostrating himself on the ground, and shouted excitedly.

"What are you doing?" Lynn helped Lord out and asked with a helpless look.

Lord immediately started crying. Ever since Linn went to the wizard city of Greenriel four months ago, he seemed to have forgotten about them. He waited and waited but there was no news.

After waiting for a long time for Lin En to come back, he had become a magic star that everyone was paying attention to and the actual controller of the Yieta School.

Loud was so excited that he could hardly contain himself. He had undoubtedly made the right bet again! But just when he was fantasizing about soaring into the sky, he was not summoned by Lin En. He sent people to inquire about the situation again and again, but he only got the response that the city lord was very busy.

This made Lord wonder if he had lost his value and been abandoned.

The patience of the gang workers who had followed him before had been exhausted after several months of waiting, and most of them had already entered the workshops or went mining.

There is no way, the morale of the team has been dispersed, and it is difficult to lead the team...

If he hadn't had some fantasies in his heart, Laud would have considered learning textile technology. He heard that the work in a textile workshop was relatively easy and the pay was good.

Listening to Lord's "crying", Lin En was a little embarrassed for a moment. He was busy dealing with various affairs during this period and also had to find time to learn magic. However, he naturally couldn't say that. Lin En coughed twice, interrupted Lord's "crying", and said with a sigh.

"In recent months, I have been planning a very important matter. I wanted to entrust it to you, but it is really dangerous, so I have been hesitating whether to summon you..."

"Lord Lin, what's the matter?" Lord immediately stood up straight and asked nervously. Even the dean felt it was dangerous, so he did not agree to it.

"I need you to do two things. First, go to the Kingdom of Hadrata to collect some intelligence. Second, monitor William and find out if he has any bad ideas. If so, 'replace' him for me..." Lin En said solemnly.
