He started with the blood of various special animals.
The Echo Cameleon, along with the Shadow Mole and the Star Bird all had similar traits to one another. They were all masters of disguise.
The Echo Cameleon, despite its large size, could blend in almost perfectly anywhere. Luckily, it rarely ate meat, and even if it did, nothing bigger than rats.
The Shadow Mole had only ever been spotted at night. As for where it was in the day, nobody had ever discovered it. The Shadow Mole had a completely black body, blending in with the night.
The Star Bird could emit a white light that made it seem like a star in the sky. Each of these beings were masters of disguise, and as a result, their blood was valuable.
The Echo Chameleon's blood was not quite as rare since there were methods to find it developed over the years, but the Star Bird and the Shadow Mole could only be stumbled upon by chance.
Therefore, the price he had paid for this was not low at all. Yet, even with the high prices, he had only gotten a small amount. It was not only these three species either.
It had gotten to the point that his father wrote a letter expressing how ridiculous his expenses were.
He naturally understood and reluctantly stopped spending.
Skymender did not use only the tools in the research laboratory. He had read historical records of ancient research methods and came to a conclusion that, while the current tools were faster, more efficient, and more diverse, there was a certain ancient tool that seemed better for what he was doing.
It was known as a cauldron. Although it was indeed simplistic, when made correctly, it did everything Skymender needed it to do. And it did it better than the scientific instruments in the research institute. Perhaps one day, the cauldron would be completely replaced.
But for now, it was still the best option.
Skymender had a custom cauldron made for him. In stories, the cauldron was used to concoct powerful pills that could increase a person's lifespan by thousands of years, or propel their strength into a different category.
Here, it would help Skymender create a material for the purpose of hiding information from others' eyes.
This had long stopped being solely about reading books in private even in public. He had thoroughly found interest in this.
Skymender began to mix the bloods together, starting with the Echo Cameleon, the Shadow Mole, and the Star Bird.
A flame lit up under his custom made cauldron, which was orange in color, and it slowly began to heat it up.
Skymender made sure to balance the heat around the cauldron in all areas.
He took a clean metal stick and began to mix the blood in the cauldron. It slowly began to boil, ultimately becoming a bad smelling black substance. He had expected this, but he had to try.
Luckily, he had used a very small amount.
He wasted the black substance and added the same proportions of the same three bloods. This time, however, he threw in a substance that could be both a solid and a liquid. When hit hard, it acted as a solid, but when sitting, it would act as a liquid. There were a few such materials in this world, and Skymender was able to get his hands on plenty of them. They were not really rare, and could even be created if necessary.
This section of the research institute, around 50 years ago, was actually responsible for the ability to create it.
Everything mixed together under the heat and stirring. The substance slowly dissolved into a liquid under the heat and mixed with the blood.
Skymender noted every single change he saw.
It had neither succeeded nor failed, producing a substance that did not seem to have any unique use. Regardless, Skymender stored some of it and labeled its properties. Who knew if it would be useful in the future.
He continued on for hours and hours until the day passed. He packed up his things, left, and came back the next day.
This formed a cycle of research and learning. At some point, Old Lee and his apprentice started to occasionally watch him. They naturally knew the branch of research he was practicing, but they had not paid attention to it beyond the books. Skymender was researching stuff they had never imagined. He was also using an ancient tool, something quite interesting.
It was hard to tell if he was actually researching or just playing around.
Though, knowing Skymender, they naturally guessed that he was actually researching.
A week passed, and another.
The end of his trip to the Imperial Capital was closing in on him. He naturally had to leave early and get home early in order to prepare for the new year of school, despite the fact that he had basically already learned everything he would need to learn to graduate.
It was a responsibility that he could not ignore, no matter what he was doing or how advanced it was.
During his last few days, he did not research, but began to buy stuff from the Imperial Capital. He knew that his father had asked him to stop spending so much, but it was almost impossible to get half of this stuff outside of the Imperial Capital.
He also began to pack everything he had already bought, adding a few more carriages filled with materials and tools.
He also did not forget to bring some research books with him. Although they were not focused on his topic, it was not impossible for him to learn something from them.
Even inspiration could completely change things.
It did not take all his remaining days to pack up, but he just decided to leave early. Before leaving, he said goodbye to the Fatty, as well as Duchess Vass and her daughter.
The next time he came, things would be different. He would come much older, and his entire experience would vastly transform.
As he sat in the carriage, watching the walls slowly fade away, he muttered to himself.
"Next time, my visit will not be nearly as simple."
