Also known as Magecraft, Thaumaturgy is a scientific way of using Magic. Using science as a base for creating or producing miracle-like ability that is close to Magic but is not entirely Magic.
Silver was sure that he won't be able to have Magic Circuits, but he knew he can apply these Magecrafts into Magic with much better effect.
Since he doesn't have Magic Circuits, he is not limited, nor will there be the Will of the World to stop him, plus even if there is, he's using real Magic, not Magecraft.
The first thing he learned is Projection. Learning the basic first and refining his usage of it will help him further in the next level of the said magecraft, and will also give him some insights as learning more of the basic version will lead to a better understanding of the advanced version. It is much like swordsmanship where you should learn the basic and have some enlightenment about the basics that will lead to one's own style even if the swordsmanship is the same style.
An example is when Silver trained under Kane who taught him Thunder Breathing style. Kane prefers to use the speed to counterattack rather than attack while Silver uses the speed for multiple attacks in seemingly one stroke, making his own style deadly, but will make him exhausted faster. However, that is where Silver's lineage comes in. Each time he gets exhausted, the next time he recovered, he will last longer.
Anyway, since he doesn't have Magic Circuits, at least not yet, he decided to use real magic and use the knowledge he learned to recreate it into a more mystery. Luckily, he learned the Mystic Arts, which helped him progress with his mastery over different types of magic.
At the first try, he managed to create a weapon, but it got dispersed afterwards as it does not have solid or physical body, unlike the magecraft version that can be thought of as computer, and you are the programmer who created a software and placed it on hard drive, or some disks, or even some chips that can be used for machines to make it work as if it has physical form. Meanwhile, magic needed to be learned properly and use it at a certain way of thinking, mysticism.
At second try, he managed to create Kanshō and its wife, Bakuya. But Silver prefers to call them Gān Jiàng and Mò Yé, but this world is very lucky that there's no speck of Chinese young Master virus has appeared not chinese-like country in this world, otherwise he would wipe them out in one blast even if it means killing other innocents. He doesn't care about them, why? It's because those poor people, if they happened to get stronger, they will develop Young Master virus which means that there is no cure for their illness. After all, in most cultivation novel he had read, the protagonist ends up developing young master virus, even if it is slightly smaller scale than the deadliest version.
Anyway, the story have digressed. Silver successfully created Kanshō and Bakuya without any problem. When his hands left the blades, they disappeared. Well, they are made from nothing, so they will go back to nothing, however, he can't say if the strength of the weapons were of the same as the originals, nor does he know that what he creates were only replicates of the original ones.
At first, he only added water attribute. He gave the sword a few swings in front of a fire, and it produced water, but the water was as strong as ordinary water against a fire made of magic. So, he decided to add some attribute where it will be feeding off on the user's magic power output and mana while also suċkɨnġ some natural mana in the air so that the sword won't continuously suck the wielder's Mana. He also added some magic cores on it to make it store some mana so it won't leak mana.
His now ordinary iron sword has turned into water-attributed sword and was now named as Caldis. Caldis can send a sword wave of water that can cut through metals depending on the force used and also how physics was applied. Though, it cannot destroy nor make a scratch on things made of orichalcum, it is still powerful against enemies without magic resistance of some sort as well as it can be used for close quarter fights, making an artificial Magic Swordsman on the spot, albeit unskilled.
After learning how to make Magic Crest in Magic version, he called this version as Magic Glyphs as he used some magical glyphs to form the effect of the Magic Glyphs. Magic Glyphs are crest-like magic while magical glyphs are writings with magic power and mana with unique frequencies on every letter to form a word and a magic spell.
"Alright, it's already past 5." His sense of time is very accurate to the point that he knows the exact time by observing his own body.
He's basing mainly on circadian rhythm which is a biological clock of living organisms. By sensing it using Ki, he can check the exact amount he have been awake since he woke up and by also sensing how much time left for him to get his sleep within 24 hours. It is due to this way of sensing when to sleep is how Silver developed himself a internal alarm that he can set so that he will wake up at exact time he wants.
If he wants to wake up at 10 A.M., he will wake up at 10. If he want to sleep for 5 hours, will will sleep for 5 hours, if he wants to take a nap for several minutes, he will be napping for several minutes before waking up. After that, sleeping is always on schedule as well as other things such as eating, inventing magic items, crafting weapons, and always on time, not a single one missed since then.
After getting out of the library, of course he didn't forget the project that he took an interest on, about the engine that can endlessly produce mana at constant rate. Of course, this engine will blow up any magic items even if they needed large amounts. This project is far from complete, but with the new knowledge he just acquired, he now have a way to fix the said problem with already more than hundreds of ideas but only around a dozen of possible and useful add-ons and upgrades.
As he got out of the house, he walked towards a certain pub with only few workers for now. The Hostess of Fertility, otherwise known as Benevolent Mistress. How come it has two names? Well, it started as Benevolent Mistress until it got changed after getting popular, and at the same time, got a very good cook and got a contract with the Demeter Familia that deals with agricultural part of the city and without this familia, there will be "eternal winter" even if it wasn't winter.
As the goddess of the familia is the goddess of agriculture and harvest, the qualities of their products are of high quality and is the best you can find. Because of having a contract with the Demeter Familia for fruits and vegetables as well as meats, they decided to change the name of the pub to Hostess of Fertility.
You readers already know who are those people, but I know you want to know the last one. They were the Astraea Familia. Who am I kidding? It's obviously them!
"What is nyour order, nya~?" Anya Fromel, sister of the "slowest" adventurer alive.
"I want to order the best meal." He paused as he looked at her with apathy, "Your brother is a snail, by the way. Too slow even for a level 1." He spoke very loudly.
"Haaah? You said that a level 5 is slow for a level 1? Which level 1 are you talking about? You?" A certain white haired werewolf suddenly chimed.
"Yes. I am." He released a huge pressure at the whole pub, "Do you have a problem with that?"
*BAM!*
They turned to look at the owner, Mia Grand who slammed the counter and broke it.
"Don't dare fighting in here! If you want to fight, go outside, you runts!" She also released a pressure.
Bete Loga backed down, however, the other didn't.
"Did you say something, old hag?" Silver spoke in a cold, emotionless, and apathetic voice that sent shivers to all adventurers in the pub.
*CRACK!*
He broke one of her shoulder and left without paying for anything.
But before he completely walked out, he spoke. "Remember this that you've been defeated by a newly recruited member of the Hephaestus Familia, a level 1."
Amusement, shock, awe, fear, and respect lingered around the place. No one has ever tried to argue with Mia Grand! Yet, this young man did not only argued, but ALSO broke her hand and the counter of HER pub.
There's a human girl who saw the whole scene whose quite interested. She wants to know how he became so strong.
--------------------------------
"So, you want me to train you? And in turn will pay me however much I want?"
"Yes..."
"Why..?"
"I don't have any speck of respect to those who can't progress on their own! I only learned how to fight, but I got stronger on my own.. That's how."
