The fourth place is Sylvie.

When facing this witch, Roland always felt a little uncomfortable. It was not because Nightingale told her that she had too many lies. In modern society, except for her relatives and good friends, few people would speak out in a blunt way. He had long been accustomed to the various flatteries and rumors that had been added with special effects.

He just felt that he had nowhere to hide in front of her. What's worse was that he knew that this was not an illusion, but that the other party's ability was like this. The vision of ignoring the obstacles, as long as she thought, the clothes on her body would be equal. Roland sighed secretly why he didn't have such ability, and involuntarily changed his seating position and crossed his legs.

In terms of appearance, she can be regarded as the most unique of these five witches: her long green hair straightened to her shoulders, her eyebrows were slender, and she appeared like a shadow under her bangs. Especially her amber pupils were so transparent that they had almost no depth, as if they were a mirror to reflect all the light outside. After watching for a long time, Roland always felt that a red mark would suddenly appear inside.

Sylvie's ability is very easy to understand. She can see all the scenes in her body, and her vision can penetrate obstacles. The depth of her penetration depends on her thoughts. In addition, she also has a branch ability similar to the Nightingale: she can see the gathering and dissipation of magic.

This surprised Roland slightly. If the branch abilities could be so close, what about the main abilities? He asked Sylvie this question, and the latter hesitated and said that among the hundreds of witches on the Sleeping Island, no one with the same abilities had been found. Nightingale clenched on the left to verify that this sentence was the truth.

Maybe it's because the samples are too small, Roland thought.

The last witch to appear was Candlelight.

Like Anna, she ushered in her adult life in the last year's Demon Moon. When she was underage, her abilities could only act on lighting objects such as candles, lamp oil, torches, etc. After adulthood, her magic power was stabilized and the effect was greatly enhanced. The objects she contacted could maintain their original characteristics for a period of time. For example, after applying ice, it would not melt under the sun, and still emit a burst of cold air.

This ability seems incredible at first glance, and can achieve things that cannot be done by conventional means. However, after several rounds of testing, Roland found that it was not as perfect as imagined. First of all, it is a type of enchanting ability and requires direct contact with the target. This limitation makes it difficult for the candle to solidify some high-temperature objects.

So his plan to get a drop of steel that will remain in an incandescent state forever, which can continuously provide heat for the blast furnace went bankrupt. Except for Anna, no one dared to touch a thousand-degree thing with his hands. If it turned into a piece of thin iron wire, the candlelight could hold the other end and enchant it, but this caused another problem.

That is, the further the solidification state of the object is from normal, the greater the magic power is consumed, and the shorter the sustained effect is.

Roland used ice cubes to verify this point. After the ice cubes of the same size were solidified, one was placed on a hot floor and the other was put into a water basin. The former only lasted for half an hour and melted quickly, while the latter reduced the water temperature to cold and still maintained its original shape.

This means that if it is replaced with red hot wire or steel bar, the effect will only be worse.

Finally, volume is also a factor that restricts the candlelight ability to exert. Like Hummingbird and Mysterious Moon, the larger the object is, the more magic it consumes. According to Nightingale's observation, her own magic power is at the middle and lower level, like a golden mist that has not yet formed a rich cyclone.

However, even so, this girl who looks a little introverted is still Roland's biggest gain. In the field of industrial production, the solidified object state is completely priceless. The key lies in the word "normal". Affected by heating, cooling, friction, and stress, the metal will be fatigued and the structure will deform. He does not need a drill bit that becomes hot due to friction, nor does he need a severely worn gear. If a machine can always maintain normal conditions, it means that it can always maintain maximum efficiency and highest accuracy operation.

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

...

Back at the castle office, Roland re-browsed his recorded abilities and then began to plan their future work.

"How about it," the Nightingale poked her head out of the fog. "Does any of these five witches particularly like?"

"All are pretty good," Roland responded casually.

"What! Do you like it all?"

He glared at the other party, who stuck out his tongue and walked away with a piece of dried fish in his mouth.

Obviously, at present, the most useful ones are lotus and candlelight.

With the ability to transform the terrain, he could easily build a new earth wall outside the city wall. The original wool stone cement wall was chosen to save materials and speed up the construction period. Although this could be completed before the arrival of the Demon Moon, it also restricted the expansion of the town to the west. As the population continues to increase, it is sooner or later to develop this wilderness and hide-and-hide forest.

The new earth wall will extend to the outer edge of the hidden forest, and include a forest, so that the town will be nearly twice the area. As for the extended defense line, it can be solved by expanding the source of troops and artificially guiding the attack direction of the evil beasts. In any case, compared with the wooden spear and flintlock guns in the previous year, the firepower projection capacity of the First Army has undergone earth-shaking changes, and defense measures such as turrets and turrets can also be completed with the new city wall.

In addition, he also planned to let Lian open a passage in the southern mountains so that the border town could directly reach the shallows. In this way, the town could obtain a natural harbor and trade with the fjords was more convenient. Considering the huge amount of magic to transform the rock formation, this project might take several months.

The work of candlelight 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 it goes well, Anna can also be freed from boring processing and production.

Silvie's mission is very clear, mainly to explore the North Slope mine caves and hidden forests. According to the miners, there are more than a hundred natural caves in the North Slope mine caves, and no one knows where they will eventually lead. Now that there are only 20 channels to be cleared, several types of ores have been found. Roland is very curious about how credible the so-called ancient monster nest is. Now, with the witch with perspective ability, he wants to explore the North Slope mine area completely, draw a detailed map, and let the lotus cooperate to adjust the terrain and improve the mine output efficiency.
