In Catherine's hand was Joelson's masterpiece, the ice and fire magic gun.

The origin of the invention was actually very simple.

Rudolph, who was in charge of selling potions, complained to everyone that every time he sold a potion to people, he had to demonstrate it again.

A demonstration cost hundreds of gold coins. It was really painful to use.

Joelson proposed to reduce the dosage.

As long as the power of the fire and ice potion could be demonstrated.

It was even said that in many cases, it did not need too powerful an attack.

For example, a level-3 spell could solve the battle. Using a bottle of potion that was comparable to the power of a level-5 spell was too wasteful.

Therefore, Joelson proposed the idea of a magic gun.

It was similar to the water gun played by children in his previous life.

The gunpowder was the bullet of the water gun. The user could control the amount of gunpowder used each time, and then decide the power of the magic gun.

The magic gun was equipped with a crystal test tube filled with gunpowder.

When the trigger was pulled, the gunpowder would flow into the "bullets" below.

The "bullets" were the size of a thumb, and they were polished with a thin crystal.

Then, a small wind magic array carved in the magic gun pushed the "bullets" out.

The user used his mental strength to control the explosion of the water and fire elements in the potion.

It looked a little complicated, but it was actually more convenient to use.

The Lucca family had their own weapon forger. Under the guidance of Joelson, it was easy to produce the finished product.

As the first trial user, Catherine was willing to give a very high evaluation!

"It's too convenient!"

After hearing Catherine's explanation, the female mage cried out in surprise. She liked this magic-conducting weapon very much and was unwilling to put it down in her arms.

She did not even care about her most beloved staff and directly stuffed it into the man's arms.

"It saves me the time to chant the spell. Its power is also not bad."

The female mage liked it more the more she looked at it.

Although the magic gun looked ugly, its name sounded nice.

The Aria of Ice and Fire.

It was very beautiful and filled with the romantic fantasy of a girl.

The female mage winked at the man and said to her male companion, "Qiaosen, let's buy this."

The man nodded dotingly and asked, "Okay, let's buy it. How much is this?"

Catherine smiled and replied, "Buy three or more bottles of 'Song of Ice and Fire' at one time. We'll give you a free 'Song of Ice and Fire'."

"Then we'll buy three bottles!"

The female mage said very urgently as if she was afraid that she wouldn't be able to buy it after she finished speaking.

The man's expression was very helpless.

"Darling, we only have a thousand gold coins. We still have other things to buy."

The female mage had a conflicted expression on her face. She steeled her heart and took out a money bag from under the mage's robe.

"I still have five hundred gold coins. This will definitely be enough!"

"Darling!"

The man cried out in surprise, "You actually hid money behind my back?!"

"This is the money I used to buy perfume and dresses!!"

"Alright."

The adventurer couple left with three bottles of Song of Ice and Fire and the Aria of Ice and Fire, satisfied.

Catherine was also very happy.

Three bottles of potions, 1,200 gold coins.

After deducting the production cost, they earned a net profit of 300 gold coins.

The cost of the magic gun was almost negligible.

Although the design was exquisite, it was not difficult and was very easy to copy, but there was no need to worry about it.

Because the true core of the 'Song of ice and Fire' was still the ice-fire potion.

It would be great if she could obtain the formula for the ice-fire potion.

Catherine sighed and shook her head vigorously.

It was already very good now. She could not be too greedy.

At night, Lucca residence.

Joelson lay lazily on the sofa. Behind him was a top-quality velvet cushion. Beside his hand was red wine and snacks.

Catherine stood in front of him and reported to him like a subordinate.

"I'm personally in charge of selling the potion shop. Twelve bottles of 'Song of Ice and Fire' have been sold today, and many other low-and medium-grade potions have been sold."

The situation in the other potion shop was similar.

"I estimate that this batch of potions will be sold out within three days. Can the Magic Potion Association..."

Catherine looked at Joelson tentatively.

Joelson picked up his glass and took a sip slowly. He said indifferently, "Increase the price by 10%. The weekly quantity of potions will be doubled in the future."

"Okay."

Catherine agreed without any hesitation.

What the Lucca Chamber of Commerce needed the most now was not profits, but how to survive.

Moreover, she could also choose to increase the price of a single bottle of potions.

The reason why Joelson raised the price was not because he was greedy. It was because he needed a reason for the people in the association who were addicted to potion research to devote more energy to make the potion that the Lucca Chamber of Commerce needed. Otherwise, they would not be willing to spend their energy on a potion that had already been successfully developed.

"The magic gun is also very popular."

Joelson nodded and said, "You can find someone to design the appearance of the magic gun more beautiful, and even launch different models of guns with different upper limits of power. The aesthetic standards of men and women are not quite the same. Well, you should be better at this than me."

Catherine suddenly felt that everything was clear in front of her.

Joelson's words opened a new door for her.

Yes, many mages would still care about the appearance when choosing a magic staff.

As a magic weapon, the magic gun still had a lot of potential.

When the time came, the magic gun could even be sold as a single item. Different styles, different powers, different types, all of them could be separated.

Just like how women would never complain about having too many dresses, mages would never complain about having too many magic tools.

"Wait until there are imitations on the market, then push out the new magic gun. This piece of cake can not be eaten by one person, but the biggest bite will definitely be in the mouth of the Lucca Chamber of Commerce."

Catherine's eyes flickered.

After carefully tasting every word that Joelson said, she felt that it was very reasonable.

He was a business genius!

Joelson sat casually in front of Catherine, but he unconsciously exuded a powerful confidence of control, full of charm.

Catherine suddenly felt her heart beat faster, and her ears began to burn.

Handsome, mysterious, powerful, terrifying talent, and an outstanding business mind.

Joelson became almost perfect in Catherine's eyes.

Catherine tried hard to push Joelson's figure out of her mind, and she couldn't help but smile bitterly in her heart.

Could it be that she had fallen in love with a man three years younger than her?

Her own sister still had some feelings for him!

"Well, I should go back."

Joelson stood up and said goodbye to Catherine.

Catherine walked him to the door with slight respect.

Joelson suddenly turned around.

"Oh, right, I need something as soon as possible!"

Catherine nodded seriously. "I know. Benson has already brought people to the Elf Forest."
