The devil is getting more and more and we are getting less and less.The holy city of Taqila has fallen, and we are running away.Crossing mountains and crossing rivers can run away from the gates of hell.But next time, where can we escape?

“What do you think?”In the office, Roland closed the book of illusion and asked the book.

"If the knight is not mistaken, it is a coincidence."The scroll is silent for a moment, "the contents of the treasure map coincide with the essay recorded in the ancient books, and it can be said that the church has built a city in the depths of the wild land to resist the devil."The location indicated by the drawings may be the defensive towers, sentries, warehouses or other facilities they have built.”

“You mean... it’s not really a treasure map?”

“Of course, the church is not a mountain thief or a pirate, and they do not need to pick up the treasure and leave a drawing for the convenience of future generations.”

Roland nodded, “Also said it.”“Is this actually a map?”

“Ten of them**.Although it is not clear why the Church did not record the history of this period, I think there must be more than one remnant buried in the eastern forest.”The book analysis said, "If the facilities marked by this location are only above-ground buildings, it is difficult to leave anything behind for hundreds of years."However, if it comes with a storage warehouse such as a basement, it is likely to be another underground relic.Through it, we may be able to find some clues.”

“What clue?”

Why does the church hide the existence of the devil?Why did they resist the devil, but they kept it as deep as they were?”She paused, her voice low, “And... why are they hunting witches as devils?”

Roland did not know how to comfort, had to be silent for a moment, only to slowly open the mouth, "Unfortunately, I don't know that he painted accurately and inaccurately, listen to his words, the original figure is not like a hand-drawn."

"Would you like to make a trip to the Knight's House?"

“It’s not right,” Roland vetoed, “to pass on a treasure map to a family that’s hundreds of years old, and the storeroom may be filled with stones and traps of divine punishment.”"Let's talk about it later," he said, with his fingers longer than the edge of a triangle, "we can't get enough of this place now anyway."If you think of this point at the foot of the North Slope Mountain as a mining area, the location of the six-pointed star is at least 50 kilometers away from us, almost the distance from the border town to the Changge Fortress.Except for the lightning that can reach it in a day, everyone else has to walk for two or three days, and what happens to the devil on the way... I don't want you to have any flashes of loss."

"You can first have the lightning to explore the woodland from the air, and you may find something."The book proposes.

“This is a viable plan.”Roland stood up and said, “When she comes back, I’ll tell her.”Now I'm going to the North Slope Mine, and you're going to get ready to teach the textbooks, and if you need to copy a lot of copies, you'll have to go on to teach them."

Roland combined his teaching of the Enlightenment in elementary school with the court education of the four princes, and instilled in the books, including classified memory, phonetic reading and writing, and reciting phrases.With these, he believes that the other party will become a good teacher.

“Yes, Your Highness.”The book is polite.

The firing room backyard of the North Slope Mine is now more than twice as large as before, and there are still two holes on the ground that have been dug up, and the gun embryo of the twelve-pounder cannon is cast here.When Roland arrived in the backyard, Anna was practicing her new abilities, and there were two pieces of made on the table that looked like steel pipes.

He picked up a look down, the steel pipe is round, the surface without pores of the parts are flat and smooth, the middle of the round hole and the outer wall, aligned with the sunlight can see the straight light area.Roland used his nails to get the wall thickness of the two ends of the card and found that it was basically the same.

Roland exclaimed, “How did you do this?”

"You see," said Anna, taking a freshly cut steel rod, flat in her hand, a thin black thread inserted from the end until it ran through the rod completely, and then rotated around the center, and the opening was done.

Amazing ability, he thought, to cut objects with a hot magic thread, and the accuracy was manageable, and Anna was enough to push the town’s industrial products to a new height with the power of one person.He pressed the excitement and said, "Let's do some basic testing first."

Basic testing includes capability range, capability strength and duration.

The Nightingale also emerges from the fog, where she is responsible for observing the magical changes in Anna's body.

The results show that in addition to the substantial increase in capacity strength and duration, the black flame is still between five meters, and it can only be accurately manipulated within three meters.

At the same time, it still belongs to the summoning ability, the stone of divine punishment can lift the black flame effect, or when Anna orders the black flame into the scope of the god penalty stone, it will suddenly disappear.

It seems that unless you have evolved to be able to use magic directly, you can't get around this hurdle.Roland thought.

However, Anna's new ability still has earth-shaking significance, using black flame to make industrial mother machines, and then producing various machine tools, and machining level is a shortcut to a rapid rise.

However, industrial production has never been something that can be done by one person.For example, the furnace that Carr built on the northern slopes of the hill is now completed.After being put into use, it was found that the firing of clay bricks was still good, and the temperature of burning cement was always not up to standard, so that the cement required by the border town still depended on Anna to produce good in adulthood, and she could complete the calcination even if she did not stay in the dusty room.

Roland is not unable to solve the problem of not going to the furnace temperature, for example, you can use the steam engine to blow the wind to improve the temperature, and then set up the exhaust gas circulation channel to improve the use of heat loss.But the production of the steam engine is also inseparable from Anna, from the key components to the welding, she has to do it.

It can be said that the current industrial products in the border town are based on Anna's ability, and once she is gone, the so-called industrial development is just a mirror.

In the month of the devil, Roland did everything for emergency, and now the threat of the evil beast has ceased to exist, and the long song fortress has provided a large number of people and funds, and he naturally has to start to change this situation.

Start with the most basic.

He asked Anna to cut out a two-finger-wide, one millimeter thick sheet of steel, and then pick out the standard centimeter length iron ruler previously formulated, take a short distance as the fixed length of the black line, and arrange it repeatedly until the ten black lines are roughly equal to the standard centimeter length.Then let the black wire climb the steel sheet and abrogate acne abruise.Under the control of the black line, the distance between each vertical trace is almost exactly equal.

Roland intends to start with a ruler, making a batch of original samples of various measuring tools, and at the same time unified measurement.These standard units will also be written as norms and manuals to be added to the upcoming universal education.(Not completed.If you like this work, you are welcome to start the project, and your support is my biggest motivation.
