After hearing the sound of the window being knocked, the maid looked up from the heavy administrative work.

Compared to her, Edith is still too tender, she took over the government affairs from Edith some time ago, and that little girl still needs to study well for a while.

"Come in......," Serena replied weakly, and with a lift of her finger, the latch of the window was pulled open by the invisible 'mage's hand.

"How many times have I said it, don't go through the window......"

The black dragon pushed the window in with the rolling heat outside the window, and casually agreed: "Oh, then I'll walk through the door next time." ”

The familiar answer sounded in her ears again, and the maid couldn't help but raise her hand and rub her sore temples, take a deep breath, and decide to divert the subject: "And then?

After closing the window, Cervantes muttered for a long time when he heard this question.

"Sizzle...... What do you mean?" he scratched at his hair, looking a little tangled.

The maid put down her work for the time being, held her cheek in one hand, looked sideways, and did not make a sound to urge.

“...... Maybe it won't be long before we see astral whales on the edge of the Black Forest!" Cervantes affirmed.

Hearing this, the maid's face changed slightly, "Is the speed at which the concentration of mana increases so fast?"

However, this is not a bad thing, after being impregnated with magic, many ordinary materials become magical materials - when a certain metal, plant, or spring water is given 'characteristics' by magic and stabilized, it becomes a 'magic material'.

These magic materials can be used to make all kinds of magic objects and magic potions, and can be used to hold various rituals, and as we all know, dragon blood is one of the magic materials, but ordinary dragon blood is not very useful, if you want to create powerful magic objects or magic potions, you need to use more precious heart blood.

These magic materials can be used to craft magical objects, and they can also be used to make magical machines, but the only thing to worry about is that those magic materials are found in the Black Forest.

No matter how high the concentration of magic in the world of Assatom is, it is impossible to impregnate everything in the world into magical materials, otherwise, as long as they touch the magic element, human beings can quickly transform into a new type of 'demonic beast' or 'monster', but is it possible?

The maid was slightly startled and then sank her heart, her mind immersed in thought.

First of all, her plans may be a little bit ahead!

Although the three magic energy furnaces have all been put in place, the construction of the Great Wall has not yet been completed, even if she can use the mountains and rivers as a pen to sketch the earth at will, as long as the Great Wall in the north is not completed in one day, she will not be able to complete this huge magic circle.

The Great Wall is also a part of this magic circle, and it is also the most important part, the Great Wall is the 'symbol' of the magic circle, just like the magic of communication must use the 'mirror', 'conch' and other items as carriers, if there is no symbol, it is absolutely not enough to complete this magic circle with only four magic energy furnaces.

Thinking of this, the maid suddenly rummaged through the report on the 'Great Wall Construction' that had been presented to her today, and if she remembered correctly, the Great Wall should have been ready to be built.

Since the preparation began in the autumn of last year, the construction of the winter officially began, and now half a year has passed, without the help of magic, it may have taken ten or twenty years to build the Great Wall in this era, but with the intervention of magic, the time can be shortened to about a year.

"It will take half a year ......"

Looking at the estimated time on the report, the maid frowned.

Cervantes woke up from his wandering world and asked, "What?"

"It will take half a year to ......," the maid sighed, "that Great Wall can be fully completed, and even if the three sections start at the same time, the construction speed is the fastest, and it can only be completed before the end of the year." ”

This is already the fastest construction speed, in order to build the Great Wall, she sent all the idle mages of the [Star Sea Boat] over, obviously researchers, but they have to waste resources to do labor work.

If you don't think about the lives of the workers and let them work overtime to build, it can be done faster, but definitely not much faster.

It is precisely because of the security of life, the food and clothing that those civilians who have worked for half their lives are willing to follow her, and the good days have just passed, and they are far from being corrupted by the days of peace and abundance.

Now that they are willing to work hard, they have increased their work efficiency to the point where they are close to the limit, and instead of squeezing their labor and causing complaints, it is better to let them eat and sleep well, and at the same time get a good reputation, they can also speed up the progress of work.

The current situation is not so critical that it needs to squeeze labor, and Cervantes only said 'soon', although because this stupid dragon can't count, she can't be sure how long this 'soon' will be, but it is also impossible that a star whale will visit the border of the Duchy of Sorrow a day or two later.

With a long sigh, the maid put the matter aside for the time being, and continued to ask, "What about the other things, such as the trees in the Black Forest?

The room was quiet for a while, and the maid looked up, but saw the bewildered expression on the stupid dragon's face, and a sense of foreboding suddenly arose in her heart.

Her face turned dark, and the maid asked in a deep voice: "Cervantes, don't tell me, you didn't pay attention to this!"

"No, no, no, of course I noticed!"

Cold sweat broke out on Cervantes' head, "Uh, just, just...... I need to think about it! Plants, of course plants have mutated...... Animals have mutated, how can plants not mutate! Plants, plants ......"

The maid narrowed her eyes, she was going to listen and see what the black dragon could make up.

"Like, like the tree in the Valley of the Golden Coins, there is a cannibal forest in the Black Forest......"

The corners of Serena's mouth hooked coldly, "Oh, and then?"

Cervantes swallowed, his eyes rolling in his sockets, trying to remember what he had seen along the way—not to underestimate the memory of a dragon, even though it was all a wandering eye!

"Rubber tree! I also found a rubber tree!"

The black dragon's eyes suddenly lit up, and he gestured with both hands, "It's so big, so high, it can produce a lot of natural rubber, and the production speed is very fast!"

"Oh......"

The maid smiled slightly, and asked softly, "And then, what about the seeds of the rubber tree?"

Cervantes' face turned pale at first, and then quickly turned gray, "No, no ......"

The maid smiled sweetly, "Which one are you referring to?"

At this moment, Cervantes struggled for a moment, but soon, the honest black dragon who decided to follow his heart shrank his neck and said vaguely: "All, it's all gone......"

"That is to say......" The maid tilted her head, raised her eyebrows, and said with a smile, "I gave you the task before...... Did you forget?"

"No, I haven't forgotten!" the stubborn Xianlong was still trying to turn over.

"And what about the seeds?" the maid tapped her forefinger on the table, "I remember telling you that if you find a plant of economic or medicinal value, you should bring back its seed or a branch?"

Cervantes tilted his head and fell silent.

"I'm going to be on it tonight, this month!" the maid licked her lips excitedly, "As long as I'm satisfied, you're not allowed to move!"

Hearing this, the black dragon looked at his maid in astonishment.

It's only the beginning of the month...... No, no, who's the master!

A look flashed in his eyes, not knowing whether it was excitement or something else, and the black dragon decided to coax first.

'It's strategic submission!' Cervantes' face flushed with 'humiliation'.
