The fourth is Sylvie. Pen, fun, and www.biquge.info

Roland always felt a little uncomfortable in the face of this witch, not because the nightingale told her too many lies, in modern society, except for relatives and close friends, few people will be outspoken, all kinds of special effects of praise and rumors, he has long been accustomed to it.

He just felt that he had nowhere to hide in front of her, and worse, he knew that it was not an illusion, but the ability of the other party was already like this. Ignoring the impaired vision, as long as she wants, the clothes on her body are equal to nothing. Roland sighed secretly why he didn't have such an ability, and involuntarily changed his sitting position and crossed Erlang's legs.

In terms of appearance, she was the most chic of the five witches: her long turquoise hair fell straight down her shoulders, and her eyebrows were slender and she was visible under her bangs. Her amber pupils, in particular, were so transparent that they barely had depth, reflecting all the light out like a mirror. After looking at it for a long time, Roland always felt that a red mark would suddenly appear inside.

Sylvie's abilities are easy to understand, she can see everything around her - even behind her, and her vision can penetrate obstacles, depending on her thoughts. She also has a branching ability similar to that of Nightingale: she can see the convergence and dissipation of mana.

This surprised Roland slightly, if the branching ability can be so close, then what about the main ability? He asked Sylvie this question, and the latter hesitated, saying that among the hundreds of witches on the Sleeping Island, no one with the same ability had been found, and the nightingale's slight pinch on the left side verified that this sentence was true.

Probably because there were too few samples, Roland thought to himself.

The last witch to appear was Candlelight.

She, like Anna, celebrated her coming of age the previous year during the Demon Month. When she was a minor, her abilities could only be applied to lighting objects such as candles, lamp oil, and torches, but as an adult, her magic power was stabilized and her effect was greatly enhanced, allowing the objects she came into contact with to maintain their original properties for a period of time - for example, after casting on ice cubes, they would not melt in the sun, and still emit a burst of cold air.

At first glance, this ability seems incredible, and it can do many things that conventional means cannot, but after a few rounds of testing, Roland found that it was not as perfect as he imagined. First of all, it is a type of enchantment ability that requires direct contact with the target, which makes it difficult for the candle to solidify some hot objects.

So his plan to get a drop of molten steel, which would remain in an incandescent state forever, and a constant source of heat for the blast furnace went bankrupt, and no one but Anna dared to touch anything of a thousand degrees with his hands. If it turns into a thin wire, the candle flame can hold the other end and enchant, but this raises another problem.

That is, the farther away from the normal state of the object is solidified, the more mana will be consumed, and the shorter the lasting effect.

Roland verified this with ice cubes - the same size of ice was solidified and placed on the hot ground and the other in a basin of water, the former only lasted half an hour before quickly melting, while the latter kept its original shape even when the water was cool.

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

Finally, size is also a constraint on the ability of the Candle Flame to be used, as with the Hummingbird and Mystery Moon, the larger the object, the more mana is consumed. According to the nightingale's observations, her own magic was at the middle and lower levels, like a golden mist, and had not yet formed a dense cyclone.

But even so, this somewhat introverted girl is still Roland's biggest takeaway - in the field of industrial production, the solidified state of objects is completely priceless, and the key lies in the word "normality". Affected by various factors such as heating and cooling, friction, and force, the metal will fatigue and the structure will be deformed. He doesn't need a drill bit that gets hot from friction, he doesn't need gears that wear out, and if a critical part of a machine can be kept in its normal condition all the time, it means that it will always operate at maximum efficiency and precision.

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

......

Back at the castle office, Roland went through the recorded abilities and began to plan for their future work.

"How," said the nightingale, poking her head out of the mist, "do any of the five witches have a particular favorite?"

"It's all good," Roland replied casually.

"What! you like them all?"

He glared at the other man, 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 candle flames.

With the ability to modify the terrain, he could easily build a new earthen wall outside the city walls - the original rubble cement wall chose the nearest pass to the Chishui River at the foot of the northern slope in order to save materials and speed up the construction period, which could be completed before the arrival of the Demon Moon, but also limited the scope of the town's westward expansion. As the population continues to grow, it is only a matter of time before this wilderness and hidden forest is developed.

The new earthen wall will extend to the outer edge of the Hidden Forest and encompass a grove of trees, nearly doubling the size of the town. As for the elongated defensive line, it can be solved by expanding the source of troops and artificially guiding the direction of the beast's attack. In any case, the First Army's firepower projection capability had changed dramatically from the previous year's wooden pole spears and front-loading flintlock pistols, and defensive measures such as batteries and bastions could be completed by the new city walls.

In addition to this, he also planned to let Lian open a passage in the southern mountains, so that the border town could go directly to the shallows. In this way, the town has access to a natural harbour and easier trade with the fjord. Considering the amount of magic required to transform the rock formations, the project could take months.

Candleflame worked 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 relieved of boring processing.

Sylvie's mission is clear, mainly to explore the North Slope Caves and Hidden Forest. According to the miners, there are more than 100 natural caves in the North Slope Mine, and no one knows where they lead to the end. Now that there are only about twenty passages mined and cleared, several ores have been discovered, and Roland is very curious about how much credibility the rumors of the so-called ancient monster lair have. Now that she has the ability to see through the witch, she wants to explore the North Slope mining area completely, draw a detailed map, and by the way, let Lian adjust the terrain to improve the efficiency of mining.

As for Honey, Roland didn't think much of it, just to strengthen his ability to transmit information in the era when there was no radio. He needs a large number of well-trained birds to use as carrier pigeons, and he doesn't need them to be as smart as Maisie, as long as he can get the information into his hands as soon as possible.
