After taking care of the Ritual Site, Iver let Sherlock return to the bishop's residence by himself.
Sherlock had initially resisted. He had wanted to keep this matter hidden and not tell anyone who knew him that he had been turned into a child. In any case, he would return to normal once he advanced again.
That immediately gave Sherlock, who had previously felt little desire to advance, a sudden burst of motivation.
However, Iver persuaded him with a single remark: "Don't you want to go back and catch up on your sleep?" Somewhat unwillingly, Sherlock chose to obey his body.
To be fair, he really was a little tired.
After all, the previous night he had endured the Moron Curse and exhausted himself studying two subjects he was not good at. Once he had more or less crammed them into his head, Iver's ritual had reforged his body.
Sherlock had spent the whole night without eating and barely drinking any water. After reverting to the body of a thirteen- or fourteen-year-old, he had put on uncomfortable clothes, craned his neck while scrubbing the wall for an hour, and then helped Iver carry the dead cow outside. That last task had nearly worn him out completely.
"...Do you really have to drag me along whenever you do any work!? Or rather, I wasn't much help at all, was I? In the end, you did it all by yourself anyway?" Sherlock could not help saying.
"That's true, but don't even think about escaping on your own."
Iver chuckled. "Work together, play together—that's what good brothers do!"
Thus, after forcibly dragging Sherlock through the entire job, Iver used a Sacrificial Flame and went off full of energy to help Hai Na deal with the griffin matter.
Sherlock had no way to recover
