Duke's words made Serra fall into deep thought, exploring the secrets of firing porcelain, which was the century-old dream of Fra's alchemy laboratory, and generations of alchemists of Fra's alchemy experiments worked hard for this goal.

Now the opportunity to uncover the secret is in front of us, but it will take two years to get it. Does Stormcastle really tell the secrets of firing porcelain, or is there a state-of-the-art alchemy lab, as the lord says?

Sierra wasn't sure that everything Duke said was true, so he hesitated to say yes.

Seeing the hesitant expression on Serra's face, Duke was not in a hurry, but just looked at him and smiled faintly, a feeling of confidence. Because Duke is well aware of the fanaticism of these alchemists and scientists for the unknown, especially since the Fra Lab has not figured out the secrets of firing ceramics for hundreds of years, they definitely want to achieve their goals at all costs.

Sure enough, after a few minutes of silence, Serra finally made up her mind and said, "Lord Duke, I accept your request to join the alchemy laboratory of Stormcastle for two years, but I also hope that you will keep your promise. ”

"No problem, I'll let the servant take you to meet Galileo, and when you see his science labs, you won't regret your decision!"

After saying this, Duke asked the servant to take Serra to the back garden to meet Galileo, Duke believed that with the alchemist's enthusiasm for experimentation, Serra would be immediately attracted by Galileo's invention, and it was estimated that he would be happy at that time.

"Duke, are you really going to tell Sierra the secret of firing porcelain?"

Gandalf asked Duke when he saw Sera go out.

"Of course, with the massive sales of porcelain now, it is estimated that the excuse of the Seris Empire is not good. Even Serra, who is far away in the Milan Empire, has guessed it, do you think the old foxes who are concerned by the Francois Empire will not find out?"

"Maybe it won't last for two years, it is estimated that all the forces on the mainland want to dig the gold mine of porcelain, and if we are not strong enough by then, it is estimated that we will be forced to hand over the method of firing porcelain. In that case, I'm just a blank check, and two years can change everything, maybe Serra won't want to leave by then?"

After saying this, Duke had a sinister smile on his face, as long as Serra agreed to stay, Duke had countless ways to keep Serra. Since he will become his own person, it doesn't play much to tell him about the porcelain firing method.

Faced with Duke's little fox-like sinister smile, Gandalf smiled gloomily at this time: "Little one, you also thought the same way when you recruited me as the chief mage. ”

Hearing Gandalf's words, Duke knew that the Archmagus's fragile self-esteem had flare up again. But there is no way, who called the great mage who is admired by all the people in this world, but was called as a thug and coolie in Storm Castle, Gandalf has always been very unbalanced in his heart.

It's just that Duke has firmly grasped his interest in science, and even if Gandalf is extremely unhappy, he still thinks that Stormcastle is much more interesting than the rest of the continent, and he is reluctant to let him leave.

"Of course not, you're a venerable archmage, and it's my honor to stay in Stormcastle!"

Anyway, now that Gandalf has been eaten, it's nothing to make the whole old guy happy with a couple of bluffs. In fact, although Gandalf is a good person, this guy is very good-looking, and he always cares about his honor as an archmage.

"By the way, Gandalf, why did you come here all of a sudden?"

Don't talk about Duke, he hasn't noticed that Gandalf has been inventing with Galileo every day during this time, except for the Sea Clan's attack, he basically hasn't seen a human figure, and today he rarely appeared in the hall, is it because of Serra, he is interested in the famous alchemist of this continent?

Faced with Duke's question, Gandalf seemed to remember something, and a fanatical expression appeared on his face and said: "We have invented the kind of microscope you mentioned before, and through the microscope, Galileo and I have seen a lot of subtle things, which may be the cells and bacteria and other microorganisms you mentioned before, so I came to inform you that you can let Copernicus and Vesalius two people, and the microscope can be used in medicine, maybe we will be able to defeat the whole demon of the plague in the future!"

Defeating the plague is the wish of almost everyone on the continent of Europa, because almost everyone in this world has faced the pain of relatives and friends who have been taken away by the plague, even the Holy See and the royal family.

In the same way, the plague is also the most terrifying demon in the eyes of people, and the reason why witches are so prejudiced and discriminated against is because the Holy See has designated witches as the propagators of the plague, causing them to become the public enemies of the people, and there is almost nowhere to hide.

Now that the microscope has been invented, the two medical scientists, Veisarius and Copernicus, have been able to enter the microscopic world through the microscope and find out the real cause of illness. And with the microscope as the foundation, Duke's previous plan for penicillin also has a basis for implementation.

It can be said that penicillin is a clarion call for human beings to fight back against various diseases, and since then, the emergence of various antibiotics has finally allowed human beings to have the ability to protect themselves in the face of nature, instead of resigning themselves to fate when they are sick like before, which can be regarded as the prelude to modern medicine.

"Very good! Send the microscope and Vesalius and Copernicus over, it will be a revolutionary breakthrough in medicine on the mainland!"

Seeing Duke so excited, Gandalf's face also had a smug expression, because the invention of the microscope was the result of his joint efforts with Galileo. As an archmagister, he can master magic at the top and fight science at the bottom, so it's no wonder that Gandalf can't be terrified.

The losses caused by the Sea Clan's sneak attack began to slowly recover as all aspects of Stormcastle were running at full speed. Moreover, the dungeon's interrogation of the Naga Commander also brought good news, that is, this sneak attack was not the will of the Sea Clan Atlantis Empire, but a private agreement reached by a Sea Clan tribe in the Sea of Death.

Because if the Sea Clan attacks in an all-out way, it will not be as simple as a stronghold, but an attack on the Terrans. At that time, even if the French Empire and the Holy See wanted to part with Stormcastle, they would not be able to do it. Because letting the Sea Clan go ashore will be a challenge to the post-war order of the Five Clans thousands of years ago, in order to show the control of human beings over the continent, a full-scale war will inevitably break out, which is a situation that neither the Sea Clan nor humans want to see.

When this news came, Duke finally breathed a sigh of relief, at least he didn't have to face the dilemma of fighting on two fronts. But there are gains and losses in this world, and news came from the treasury of the town hall that the consumption of magic crystals during this time was too large, and there was a shortage of them.
