Alien Knights

Around six o'clock in the evening.

After hastily eating dinner and thanking Master Myris for his generosity, Todd buried himself in his room with a few blank sheets of paper, a set of rulers, a few charcoal pencils and half a candle from the lecture, and started the work he was best at in his previous life.

Design of chemical experiments and practical industrial applications.

In the afternoon, by observing the waste slag extracted from the silver mine and asking the craftsman Aiden for verification, Todd already had a certain plan for the next work.

The "Northern Stone Mine" mines and smelts silver ore. Although the "ash blowing silver smelting method" is used, because the royal craftsmen's understanding of mineral elements and chemical reactions is still in its infancy, only about 60% to 70% of the silver in the ore is extracted, and about 30% of the silver is still lost in the waste residue, which is sent to the San Sidro Monastery as garbage.

Why is there such a loss.

Mainly because there are some impurities in silver ore, such as bismuth, tellurium and lead oxide.

Due to these impurities, they have great affinity with gold and silver, and are not easy to be oxidized, precipitated and attached to recover, and can always be copolymerized with silver in the lead liquid during the ash blowing process, thereby reducing the recovery rate of silver.

The smelting in the middle world, due to the lack of understanding of metal refining, often stopped the operation after the first stage was blown. What Todd has to do is to carry out the extension of the second and third stages to further extract the silver and reduce the loss caused by impurities.

The principle is probably like this. The key is how to rely on the existing equipment and materials at hand to carry out secondary and tertiary re-refining of silver ore waste residue.

Desperately recalling the content of elective courses during his master's and doctoral studies, Todd tried his best to write down the known information as much as possible on paper.

If you want to extract the silver remaining in the waste slag, don’t even think about the electric furnace ashblowing method in the early 19th century. The wheel ashblowing method in the late 17th century and early 18th century is also impossible. Even the tall cylinder ashblowing furnace in the mid-16th century is difficult to achieve under today’s conditions.

In comparison, only the early cladding ashblowing furnaces in the late 13th and early 14th centuries can barely reproduce.

While recalling the shape of the furnace body in my mind, I used charcoal pencils and rulers to draw on the white paper the steps of refining and the improvement of the utensils.

Todd, who was addicted to scientific research, quickly forgot the passage of time.

In the end, it was the candle that was burning to the end, reminding him of the time for work and rest.

Looking at the half-finished drawings in the dark, Todd held his forehead depressed. The feeling of being forced to stop after half-finished work was the most intolerable for him.

Through the bricks and tiles above his head, he looked at the bright moon hanging high in the sky, sighed, and had no choice but to climb into bed and choose to sleep.

Early the next morning.

The robin's waist clock became the last sound he wanted to hear.

But he also knows clearly that if he delays the morning class, it will not only arouse unnecessary suspicion from others, but even make him unable to stay here.

Bracing himself up, putting on the monk's clothes, rubbing his sore eyes, Todd carefully folded the drawings on the table and stuffed them under the bed. Although the labels on the drawings are in Chinese, and no one has seen the chemical elements and equations, it is better to be cautious about this kind of thing.

Hiding in a corner, yawning, and finishing the morning lesson with everyone, Todd had to rush to Master Myris to learn a new lesson.

Grammar, rhetoric, logic, arithmetic, and geometry are acceptable to him, but music and astronomy are really killing him.

Music is relatively better, firstly, he doesn't know it, and secondly, he is not interested, and the class is just perfunctory.

Astronomy is the biggest problem.

Let a soul who has been baptized by modern civilization accept the education of church astronomy, let alone a teacher with a background in scientific research.

In his head, he clearly yelled nonsense and nonsense, and he still yelled that it was so, and he was taught.

During the lecture, perhaps seeing that Todd was not in high spirits and in low spirits, Master Myris rarely interrupted the class and started talking with the apprentice opposite.

"You are the most talented student I have ever seen."

Hearing that the old man sitting across from him came up and put a "high hat" on himself, Todd said something bad in his heart, and quickly put on an appearance of listening attentively.

"Heavenly Father has given you protection and blessings. There is no doubt about it. If you calm down and devote yourself to practicing, you may become the first among us to approach a sage."

Todd still lowered his head, vaguely feeling that the hat on his head would soon break through the roof and point to the sky.

"but……"

Cursing his lips, Todd touched the bridge of his nose with his fingers, thinking to himself, there really is a but.

"Don't waste your time and energy on those trails."

Edgar, you have a big mouth!

Todd thought to himself: I just guessed that it must be Edgar, the bastard who talked about these nonsensical topics today, and reported what happened yesterday to Master Miles.

Todd, who was still unwilling to give up, raised his head and tried to persuade the old man: "Master, if I have a way to improve everyone's life a little, wouldn't it help everyone to better understand the true meaning of the Holy Way?"

"No, my boy, that is not the right idea."

In Todd's impression, it was the first time that Master Meris had such a serious expression on his face. He said, "The idea of ​​improving life is just an excuse for laziness and sinking. A comfortable life will wear down our will, dull our thinking, and empty our body. A monk who truly has a heart for the Holy Way should abandon all distracting thoughts and all vulgar things, and dedicate his whole life and spirit to the Heavenly Father!"

The corners of his eyes twitched, and Todd wanted to argue again, but after thinking about it carefully, he realized that this was definitely not a good idea. He quickly buried his head down, closed his eyes, and prevented the old man from seeing his questioning and dissatisfied expression.

After a long time, Todd choked out a sentence from his throat.

"Follow the teacher's instructions."

—————————————————

After completing his studies in the morning, Todd, who walked out of the classroom, felt that the world was gloomy.

Obviously there is a way to eat exquisite food, wear brand-new clothes, and not have to get up early and late to work and run around every day, and can devote more energy and time to research and academics.

Why refuse such a life?

He can't understand.

Out of the corner of his eye, he caught a glimpse of a figure appearing in the corner of the wall.

Seeing clearly who was coming, Todd was furious immediately. He took off his shoes and ran away with them in his hands, cursing, "Edgar, you little bastard! I want you to tip off the bad old man!"

Following the escaping figure ahead, through several corridors and around several corners, Todd crashed into someone's arms.

Huggins, who had been waiting for a long time, dragged the grimacing Edgar behind him, and said to Todd, "I heard that you have a way to improve our...life?"
