The Energy Suction Spell
"Where am I?"
The moment Jim went to sleep, he found himself standing inside a place he recognized well enough.
'This is the place of your training,' the old man said, 'don't you recognize the stadium?'
"I... don't understand."
'You took a sleeping potion,' the old man explained, 'and with a little help from me you can get benefits here by training during sleep.'
"I... can do that!" Jim was surprised while glancing around. It was the stadium, the moment he won the tournament. "Wait a minute, how about the time difference?"
'It's much less disturbed as you got here with a sleeping potion,' the old man said, 'but there is still a time difference.'
"Then I can go inside that closet, right?" Jim grinned before adding, "this way the time difference will be negated, right?"
'Can't tell without trying.'
