They continued until the end of the day doing simple exercises and going through a back-and-forth of what Lukas could improve. By the end of it, Lukas had a mental list of things he wanted to try once he had recovered. Parts of it were already slipping away from his memory, so once he got back to his room he wrote down as much as he could remember.

After eating something he went to bed. Although it took him some time to fall asleep, he eventually managed to dull his mind enough that it naturally drifted to slumber.
