Development Bottleneck

"It could be projected, but if it was used in battle, it could only be maintained for a very short time."

Shirou Emiya shook his head helplessly.

"Not even a minute."

Moreover, he could only project the armor itself. He could not truly replicate the immense power contained within it, so naturally he could not use the armor's power to unleash the corresponding Finishing Moves.

Yinsen nodded. This was hardly surprising. Shirou Emiya's greatest weakness right now was that his magical energy was too low.

Even after receiving continuous guidance from Illya, Rin Tohsaka, Scáthach, Artoria, and Yinsen, and inheriting Magic Circuits, Projection Magecraft, the correct use of Reinforcement Magecraft, and abundant combat experience from Emiya, his lack of magical energy had never improved.

Yinsen had never brought up Shirou Emiya's magical energy because, to him, it was the easiest problem to solve.

He had far too many methods capable of drastically increasing Shirou Emiya's magical energy. There was no need to rush into raising it. Instead, he had Shirou Emiya start over with all kinds of foundational knowledge, planning to improve his magical energy only after his foundation was solid enough.

"You can relax a little from now on."

After a string of battles and rapid growth, Shirou Emiya had accumulated plenty of experience and ideas. Now he could settle down and slowly digest what he had gained over the past year while building up his magical energy.

Besides, Shirou Emiya said that he wanted to go home and take a look.

He knew Yinsen intended to invite him to join, and he was not opposed to joining Yinsen's team either—he clearly understood that ever since he had inexplicably gotten mixed up in the Holy Grail War, he could no longer live an ordinary life like a normal person.
