The fourth is Hilvy.

In the face of this witch, Roland always felt a little uncomfortable, not the nightingale said that she lied too much, in modern society, in addition to relatives and good friends, few people will be outspoken, all kinds of special effects touts and rumors, he has long been accustomed to.

He just felt that he had a sense of nowhere to hide himself in front of her, and even worse, he knew that this was not an illusion, but the other person's ability to do so.Ignoring the sight of the obstacle, as long as she thought, the clothes on her body were nothing.Roland sighed why he did not have such an ability, and involuntarily changed his posture and raised his legs.

In terms of appearance, she is one of the most unique of the five witches: a long green hair falls on her shoulders and her eyebrows are slender, and she is shadowy under the Qi Liuhai.Her amber eyes, in particular, were almost transparent, as if a mirror reflected all the light.After looking at it for a long time, Roland always felt that a red mark would suddenly appear inside.

Hilvi's ability was so well understood that she could see all the sights in her body—except behind her, and the view could penetrate obstacles, depending on how deep she was.She also has a branching ability similar to the Nightingale: she can see the magic aggregation and dissipation.

This made Roland a little surprised, if the branching ability can be so close, then what about the main ability?He asked Hilvi about this, and the latter hesitated, saying that among the hundreds of witches on the sleeping island, no one had found the same ability, and the Nightingale gently verified the words as true on the left.

Probably because there were too few samples, Roland thought.

The last witch to appear was a candle.

Like Anna, she reached her adult life in the last year’s demonic month.When she is a teenager, her ability can only act on candles, lamps and oil, torches and other lighting objects, and the magic is stabilized in adulthood, and the effect is greatly enhanced, and the objects she can contact maintain their original characteristics for a period of time - for example, after the ice is applied, it will not melt under the sun, and still emits a chill.

At first glance, this ability seems inconceivable, and can achieve many things that cannot be done by conventional means, but after several rounds of testing, Roland found that it is not so perfect.First of all, it belongs to a demonic possession ability, which requires direct contact with the target, which makes it difficult for candles to solidify some high-temperature objects.

So he tried to get a drop of steel that was always in the incandescent state, and the plan to provide a constant heat source for the blast furnace was bankrupt, and no one except Anna dared to touch the stuff of thousands of degrees with his hand.If it becomes a thin wire, the candle can hold the other end of the demon, but this raises another problem.

That is, the farther away the solidification state of the object is from the norm, the greater the magic of consumption, and the shorter the continuous effect.

Roland verified this with ice blocks—the same size of ice was solidified, one on the hot ground, one into the basin, the former only insisted on half an hour before melting, while the latter lowered the water temperature to cold and still maintain its original shape.

This means that if you switch to red hot wire or steel strips, the effect will only be worse.

Finally, volume is also a factor that restricts the ability of candlelight, and like hummingbirds and enigma moons, the larger the volume of the object, the more magic is used.According to the observation of the nightingale, her own magic is at the middle and lower levels, like a golden mist, which has not yet formed a strong cyclone.

But even so, this seemingly introverted girl is still Roland's biggest gain - in the field of industrial production, the solidified state of the object is completely priceless, the key lies in the word "normal".Affected by various factors such as heating and cooling, friction, and force, the metal will fatigue and the structure will be deformed.He does not need to be hot due to friction, nor does he need to wear and tear gear, if the key parts of a machine can remain normal, it means that it can always maintain maximum efficiency and maximum precision operation.

In other words, burning can effectively improve the mechanical strength of inferior metals.

...

Returning to the castle office, Roland re-read the recording ability and then began to plan their future work.

"Well," came the Nightinge poked out of the mist, "is there any particular favorite of these five witches?"

“It’s all good,” Roland responded.

“What!Do you like it?”

He glanced at each other, who spat out his tongue and walked away with the fish.

Obviously, at present, the most useful is lotus and candlelight.

With the ability to transform the terrain, he could easily build a new earth wall outside the city wall - the original Maoist cement wall, in order to save materials and speed up the construction period, chose the northern slope of the foothills and the nearest pass of the Redwater River, which can be completed before the arrival of the demonic month, but also limited the scope of the town to the west.As the population continues to grow, it is sooner or later to develop this wilderness and hidden forest.

The new earth wall will extend to the outer edge of the hidden forest, and a forest will be included, so that the town will be nearly twice as white.As for the lengthening line, it can be solved by expanding the source of troops and artificially guiding the direction of the evil beast's attack.In any case, compared with the previous year's wooden pole spear with a front-loaded flapping gun, the fire projection capability of the First Army has undergone earth-shaking changes, and defensive measures such as forts and bastions can also be completed by the new wall.

In addition, he also intends to let Lian open a passage in the southern mountains, so that the border town can go directly to the shoal.In this way, the town can get a natural harbor, and trade with the fjord is more convenient.Given the huge amount of magic to retrofitting rock formations, the project could take months.

The work of the candle is to cooperate with Anna and Lucia to create a new generation of machine tools for the production of firearms and other mechanical equipment.If all goes well, Anna can also be freed from the boring processing and production.

The task of Hilvi is clear, mainly to explore the North Slope mine and the hidden forest.According to the miners, there are more than a hundred natural caves in the North Slope caves, and no one knows where they will eventually lead.Now mining, clean up out of the channel is only more than 20, has found several kinds of ore, Roland is very curious about the so-called ancient monster nest rumors in the end how much credibility.Now with a witch with the ability to see, he wants to explore the North Slope mine completely, draw a detailed map, and let Lian cooperate with the adjustment of the terrain to improve the efficiency of the mine.

As for honey, Roland didn’t have much thought, just to strengthen his information-transmitting capabilities in an era when there was no radio.He needed a large number of trained birds to use as pigeons, not to ask them to be as smart as Maisie, as long as they could get the information into their hands as soon as possible.(Unfinished.
