Another week passed. During this time, Locke and Alicia deeply exchanged knowledge about potion studies, with both benefiting greatly from the exchange.

Alicia's understanding of potion studies, as well as the best potion studies education she received at Virdantia University, greatly enhanced Locke's understanding of the field of potion studies.

Similarly, during this week, Locke used the Synthesis Cube to synthesize the southeastern quadrant's common First Circle potion [Spirit Spring Soul Surge Potion], synthesizing a level 8 synthesized item.

In its improved formula, the method of using thunder-attribute magical flame at the heat stage to suddenly extract large amounts of medicinal properties from potion materials in the final step could greatly enhance the Spirit Spring Soul Surge Potion's efficacy.

Because Alicia had helped him greatly with potion studies fundamentals, Locke, as a return, also shared this knowledge with her.

For no other reason than that exchanges should be reciprocal.

Otherwise, one-sided exchanges would become teaching.

This kind of communication would be difficult to maintain long-term between peers.

With Alicia's help, Locke filled gaps in his knowledge, rapidly supplementing his inadequacies in the fundamentals of potion studies, solidifying the foundation of potion studies that had originally been somewhat inferior to breeding studies.

The two found common ground in Locke's suite.

Alicia sighed to Locke, "Locke, I've never discussed the field of potion studies so deeply with a peer wizard before. You know... most wizards actually can't keep up with my thinking speed in potion studies. Even my teacher, that's only because his knowledge is deeper than mine and he's older than me."

"Although Locke, your thinking speed seems very slow." Alicia frowned as if thinking about how to describe it. "For some things, I have to tell you two or three times before you understand."

"At first, I thought I would also have difficulty communicating with you. But later I discovered it wasn't like that. Many of your ideas are truly ingenious and imaginative, unexpected even to me. For example, using the violent rapid extraction of thunder-attribute magical flame in the final stage to accelerate the fusion of seven magical nectars, gathering them into one Spirit Spring Soul Surge."

Alicia said, "This might be related to thinking patterns. If my thinking habit is doing addition, slowly accumulating numbers upward, then your thinking habit is very likely doing multiplication. Although your thinking speed is usually very slow, suddenly you'll have an amazing inspiration appear."

"Overall, you still think faster than me. Your thinking leaps too quickly. Actually, I can't quite keep up."

Locke smiled helplessly.

That was because much of his potion studies formula knowledge was obtained through the Synthesis Cube cheat device, while Alicia's ideas were entirely thought up by herself.

Alicia's talent in potion studies was indeed very good. It was just a pity that during this time exchanging with her, Locke discovered she really wasn't good at the Evocation School's bloodline modification direction.

The reason she was currently only an ordinary formal wizard was largely because she was forced to learn the family's inherited bloodline modification magic, and her talent and interest in this area weren't actually higher than any other wizard.

This was the downside of large families.

You enjoyed the benefits the family brought, so of course the family could also dictate your life, forcing you to inherit the family's magic while preventing Alicia from continuing to study potion studies in depth.

It could be said that if Grand Wizard Sulla hadn't fallen ill, Alicia might not even have been allowed to study potion studies at Virdantia University outside the Land of Six Towers.

And currently, this was also the greatest degree of freedom she possessed.

Alicia pursed her lips and sighed, "Exchanging with you is truly joyful. It's just a pity that happy times are too brief."

"We're almost at our destination."

The rare happiness on Alicia's face was swept away. Worry returned to her eyes, along with her sense of responsibility as the Plutarch family heir.

Outside the observation window in the suite, the airship had already passed through the Second Sky, descended to 50km below, and was continuously circling in the sky, making a rapid descent.

They saw the airship pass through the cloud layer. Below the azure blue sky was a stretch of continuous mountain ranges. In the plains regions and some steep mountainous highlands surrounded by these continuous mountains, there were cities.

Different from the southeastern quadrant, this region was everywhere dotted with sharp, steep wizard towers. Towers stood erect among mountains and cities. The tops of the wizard towers emitted magical light sources reaching straight into the clouds. Massive magical energy surrounded the wizard towers, continuously pouring energy into them.

Locke even saw many regions' wizard towers continuously releasing magical energy toward the sky and earth, as if probing for something. At the same time, large numbers of commoners in this mountainous region were excavating magical ore. Various rare magical ores were continuously excavated from the earth.

The wizard towers standing everywhere were guiding signals for the underground miners.

At the same time, Locke also saw at the edge of this region dotted with wizard towers, six towering high towers. Those six high towers' height and diameter were all incredible, as if they were pillars supporting the sky at the world's edge.

They reached straight into the cloud layer, like pillars of heaven, massive in size, seeming like six natural buildings existing since ancient times.

These six white towers were connected to each other by magical power, forming a natural magical energy barrier that isolated the entire Land of Six Towers from the world.

Locke said, "Underground ore vein activity in the Land of Six Towers seems very active. Were the wizard towers here built for mining?"

Alicia nodded, "Mm, the vast majority of magical ore from nearby wizard lands doesn't come from the Black Wheat Underground Domain, but from the Land of Six Towers. The Black Wheat Underground Domain's underground magical ore veins are indeed abundant, but they're not near the Star Domain Sea, they're in the distant Northern Border Zone."

"Our wizard lands are all in the Eastern Wizard Zone governed by the Star Domain Sea."

"To better excavate underground ore, the Land of Six Towers has been developing wizard tower technology since ancient times."

Alicia told Locke history that even Land of Six Towers wizards might not know. She pointed at those six incredible towers, "However, most wizard tower technology is just crude imitation of those six towers."

"Those six towers were built by the Wizard Association headquarters three thousand years ago in our Land of Six Towers, specifically to form a stable barrier to protect the mining area, and to transmit signals in complex underground environments, especially those complex earth vein magical energy circulation systems, guiding miners to excavate magical ore."

"The six white towers require massive energy provision every moment. General wizard lands might not have this resource, but the Land of Six Towers is uniquely blessed. Underground is entirely abundant magical ore veins, inexhaustible and infinite. So far, the magical ore veins we've excavated are still less than 30% of the magical ore vein reserves the Land of Six Towers possesses."

Locke looked at Alicia and said, "So the Land of Six Towers' family wizards mostly excel at bloodline modification technology also because..."

Alicia smiled at Locke, "Truly worthy of being Locke. You caught on. I always admire this sharpness of your thinking. Perhaps this is why you can suddenly gain epiphany about an ingenious idea. Yes, the Land of Six Towers' earliest bloodline modification technology was to overcome the high energy radiation in underground ore veins."

"Without undergoing specific bloodline modification, even wizard apprentices can't remain long-term under the high energy circulation radiation zones of underground gem veins. Many wizard apprentices, because of long-term excavation work in underground gem veins, experienced shortened lifespans and various strange diseases."

Alicia said, "For this reason, our Land of Six Towers wizards, in order to undertake the task of excavating underground ore veins for major wizard lands, embarked a thousand years ago on using bloodline modification technology to make our bodies exhibit high adaptability."

"So, our Land of Six Towers has always been formidable in high-adaptability bloodline modification technology. It's just that in recent years it's fallen somewhat behind, but in the pursuit of high adaptability, it's still among the best." Alicia said, "Of course, now only commoner wizards go down into the mines. We family wizards rarely go down into mines, so our family wizards' bloodline modification research direction has long since ceased to be adaptability to high radiation environments."

Alicia bowed to Locke, "Locke, I should return. Exchanging with you was truly pleasant. I learned many things from you. The improvements to Mammon's Powder potion and Spirit Spring Soul Surge Potion are both your masterpieces, so I won't disclose them to others until you apply for patents and publish articles."

"Right, this is for you."

Alicia took out a letter from her astral ring, then tore this letter in half, "This is letter paper. Based on wizard tower energy radiation range, it can communicate with each other. When I write text on the upper half of this letter paper, corresponding text will appear on the lower half in your hand."

"This is our Land of Six Towers wizards' common communication method, so we call wizards communicating over long distances pen pals."

"Because it depends on wizard towers, the letter paper can't be used after leaving the Land of Six Towers."

Alicia was somewhat worried Locke wouldn't accept. She looked up at Locke somewhat guiltily and added, "My home has many potion material inventories. If you have any needs, you can write to me. I'll send you the materials."

"I don't dare say anything else, but at least in the Land of Six Towers, you'll never again lack rare potion materials."

Locke frowned. He had always followed the principle of equivalent exchange, so he wasn't quite comfortable with the current situation.

Alicia added, "As a transaction, I want to continue discussing potion studies with you. Discussing with you, I gain much. I now also have some ideas for improving potion formulas."

"So, this is all paid service."

Locke smiled at this phrase "paid service," "Alright."

He took the letter paper from Alicia's hand and said, "I also don't have many friends, especially First Circle wizards. Although you're not my only friend, you are my first First Circle wizard friend."

Alicia looked at Locke with surprise, "Isn't Wizard Salvador your friend?"

Locke got a bit of a headache thinking of Wizard Salvador. This guy's mouth was really too foul. Just staying on the airship for two months, he seemed to offend a large group of Land of Six Towers family wizards with his loose tongue.

It could only be said that Hand of the Jungle was too impressive, or that although Salvador had a foul mouth, because he had no other material needs besides restoring ecology, not many wizards made an enemy of him.

After all, people who could become First Circle wizards rarely became enemies with others over emotional things.

Both of the above were indispensable.

Locke believed that if Wizard Salvador lacked even one of the two conditions above, he might die at some wizard's hand within less than a week.

Locke shook his head slightly at Alicia, "Wizard Salvador is just my protection target. And the kind where I can't wait to immediately have him quickly get far away from me. If not for my senior sister entrusting me to protect him, I absolutely wouldn't accept the task of protecting him."

Alicia nodded thoughtfully, "But Locke, you're very reliable at protecting people."

"You're a very reliable person."
