Shirou in Another World.

Volume 2: Black and Red Clouds CH1

Early spring breeze blew through the fields, causing grass to sway and dance gently. The earth was silent, save for the sounds of gravel crunching underneath them, and the accompanying sound of soothing wind sweeping through the land.

The plants were slowly returning from their winter hibernation, new sprouts and leaves bursting from the formerly frozen soil. The sky was an azure expanse above them, wisps of cotton-like clouds floating across lazily. The sun wasn't hot, but felt nice and refreshing as it showered them with just the right amount of warmth on that early spring day.

The first hour of travelling was spent in silence as Shirou took in the views. While his reawakened soul had returned him to many memories of similar lands from his travels on his previous world, the underlying atmosphere of exploring a new land still brought excitement that Shirou was enjoying.

It was a foreign concept to the old Shirou, he had never gotten excited in his old life, a result of throwing away his humanity. But in his new life, Shirou had experienced it in abundance, and eagerly grabbed each opportunity to enjoy himself.

Truly a gift he was given for his second life.

This was a new world. A world filled with unknowns, with adventure, with excitement. Learning about everything was going to be a thrilling experience for him. What kind of nations were created, what historical events took place, what legendary landmarks existed. Encapsulating all of it and comparing it to his former world was definitely a fun project to imagine.

Shirou was already categorizing his memories of the previous world in his mind. Separating them into history, science, technology, and many other subcategories that he could remember.

How was he able to keep a good track of that much amount of information? It all came down to how his brain adapted to the constant punishment Shirou had been putting it through. The consequence with the repeated use of his Structural Analysis craft. Simply overloading his brain with lots of information from analyzed objects slowly increased the capacity he was able to take in. The result? Shirou had turned into a sponge, easily absorbing large and complex quantities of information.

General information from the modern era was simple compared to analyzing noble phantasms, and complex study topics were just a degree above general information.

There was a reason the Emiya-Einzbern family research agreement bore impressive results.

Shirou definitely did not slack when it came to magical research, being renowned for his achievements and developments in multiple fields. Which in turn proved beneficial to Rin's status due to her connection to him as his mentor.

Rin also made sure to abuse the literal cheat magician she had on her hands. Many times overexploiting Shirou to trace magical artifacts, ancient resources (sourced from the materials of ancient noble phantasms), and reinforcing her magical jewels to insane levels.

Fortunately, the two worked on keeping it a secret from the Clock Tower magi, considering that if they learned of Shirou's near infinite ability to reproduce any resource used in the crafting of weapons, which was only possible because of his reality marble, Shirou would be stamped with a Sealing Designation and locked underneath the Clock Tower as a research subject and tool for the rest of his life.

Rin simply attributed her nigh impossible collection of resources to her mentor, Zelretch. She explained that he had given her access to his storage of materials sourced from multiple dimensions.

Nobody could see past the sheer amount of bullshittery that reason was.

Zelretch was happy to go along with the bluff, enjoying the chaos it brought. Not to mention that he himself had requested a couple of rather interesting materials from Shirou's world too.
