The motor eventually stopped running on the afternoon of the fifth day. Pen % fun % Pavilion www.biquge.info

In other words, one "Dawning-1" can provide power for five days of power for a large electric motor, and if used intermittently, the working time can be extended even longer. The copper pillar that has lost its magnetization effect can be enchanted again, and it is completely a low-consumption, non-polluting, and recyclable green energy source.

The downside is also obvious, as an enchantment requires the mana of Anna, Mystery, and Speer to be exhausted, and even if the trio produce one Aurora 1 per day, they can keep up to five motors running (without turning them off). And Anna is still an irreplaceable figure in the town's finishing and steel smelting, although Roland has tried his best to hand over most of the manufacturing to ordinary townspeople, but without the supply of machine tools and materials that Anna manufactures and maintains, the production of revolver guns, bullets and other items will immediately fall into a dry situation.

Not to mention the 152mm fortress cannon, new light weapons, and all sorts of ideas of his own, Anna had to come to fruition, so he couldn't accept that the other party was spending all his magic on recharging the batteries.

Roland leaned back in the high-backed chair in his office and let out a long sigh.

To overcome this shortcoming, there are undoubtedly two ways to start, one is to continue to increase the duration of "Dawn One", which requires a larger source of mana, or an increase in the number of inputs. It's a pity that the Marquisess's magic channel is already very difficult to transport Anna's magic alone, and she is almost physically and mentally exhausted after completing the charge, and she can't do anything if she wants to bring a few more witches to power the Mystery Moon. This question only allowed Speer to get used to it - after all, she probably wouldn't be concentrating on how to improve her abilities during her time as a lord.

The second point is to replace Anna with other witches, compared to Anna, Zoroa, Agatha and others who are busy with work, most witches do not use up all their magic power every day, if the remaining magic power is used to make a metamagnetic core, it is a feasible method.

As long as the total amount does not exceed the share provided by Anna alone, Speer should be able to hold on - she has said before that the magic channel is not a one-to-one transmission, and it is completely possible to connect multiple people at the same time.

Roland put this idea on paper, as for who has more magic and who has less, how much to use every day, and how much to keep, can be handed over to the Witch League to count.

Wendy, who is trusted by everyone, is undoubtedly the most suitable person.

With this problem solved, the next step is to think about how to use this new energy source.

Obviously, unlike the steam engines in the factory, which can produce four or five units a month and can be used by adding some water to boil, limited by the number of "Dawning No. 1", it is meaningless to build more terminal converters. At the current level of mana, he estimated that the town would only be able to maintain three or four terminals at most—whether it was to use it as a source of power, boiling water, or lighting electric lights, and if the system was to run stably, he would probably have to specialize in it.

After thinking about it for a long time, Roland finally drew a circle on the light.

Although the source power, that is, the electric motor, has more advantages than the steam engine, such as stable speed, easy control, convenient automation, etc., the latter is enough to meet the current power demand. He'd also envisioned tall electric devices, such as electric cars that would travel between the fortress and the town, or electric airships that could be operated by ordinary people, but they weren't cost-effective - keeping them moving was based on a day when Anna or the witch stopped working.

This is especially true of boiling water, boilers and firewood can solve the problem, even if a few more people are recruited to take care of the maintenance, it is more cost-effective than spending mana, he is not rich enough to squander the electricity wantonly.

There are many meanings of lighting, not to mention that a stable and clean light source can greatly improve the happiness of residents, and also allow them to have better conditions for studying at night, not everyone is willing to go home after a busy day and continue to read and write in front of the dim candle.

Moreover, the capture of the legendary thunder power and the use of the people will be of great benefit to breaking superstitious ideas and improving the scientific spirit. This is probably the most intuitive understanding of the application of electric energy by the public, and airships and electric vehicles, even if they seem incredible, are far from them.

The most important point is that the weak light of the candle simply does not meet the needs of nighttime production. With electric lighting, the factory can maintain production even at night, and even three shifts if necessary, which means that the efficiency of the town will be further improved.

Once the direction of development has been set, a series of problems need to be solved to achieve this goal: such as light bulb manufacturing, wiring erection, power supply scheme, and electricity publicity.

However, these can be put into consideration later.

Thinking of this, Roland called Wendy.

"You're saying that the sisters' daily consumption and surplus mana will be counted and delivered to Mystic Moon as planned?" asked Wendy after listening to his story.

"Well, there is no need to count those battle witches who have fixed tasks," the prince nodded, "what do you think?"

In essence, it is to remove the remaining magic power after ability training, task consumption, and emergency preparation, and turn it into pieces to ensure the manufacture of "Dawning No. 1". This can not only make full use of the power of witches, but also play a role in strengthening practice, which is not a small help to increase the magic power of Awakening Day every year.

"I think Hummingbird and Echo will be happy," Wendy laughs, "and they will be able to do the same thing as Anna." But how do you measure that margin?"

"Let's use the Balance Magic Stone to make sure, this is the common way of the Federation in the past. ”

"Yes, Your Highness. She bowed slightly, "By the way, today is Lucia's coming-of-age day, do you want to gather all the members of the alliance to spend the evening with her?"

Roland was stunned, "Ah...... If you don't say it, I'll forget. ”

"There's so much to remember," Wendy said softly, "I've written down the history of each sister's upbringing in a notebook so that nothing slips out." ”

After Anna's awakening day, Nanawa, Lightning, Echo and others also spent their "second birthdays" one after another, but the meaning of adulthood is stronger. It is a special awakening day, although it happens on the same day, but the magic backlash suffered by adulthood is several times higher than usual, and it is the hardest life and death for witches to survive before they master the pain of eliminating the phagogy.

Once they reach adulthood, their abilities are stabilized and greatly improved, and some witches will awaken branching abilities, which are no less meaningful than evolution.

"Well, I'll prepare a great dinner party in the evening," Roland whispered, "not only for the League of Witches, but also for her." ”
