Creak…
Isaac slowly opened the door and stepped inside. The air was quite chilly, but it was fresh without even a speck of dust clogging up his nose.
However… Then something unexpected occurred.
Smack!
An invisible punch landed on Isaac's cheek!
''Eh?'' Isaac glanced to his right, and his cheek had a fist mark. However, he barely felt it, like someone was trying to tickle him.
''Someone punched me?''
Smack!
Then, another punch landed on his chest, but Isaac stood his ground with a nonchalant expression.
''Stop it.'' Isaac waved his hand. However, his hand only touched air and nothing else.
''Hahaha, weak!'' An arrogant voice echoed across the store. Then, an outline of a ghost appeared on the ceiling.
The Ghost was a muscular man with a buzzcut and arrogant-looking face. He had a long nose bridge with sharp eyebrows.
The Ghost raised his chin like he was above everyone else.
Isaac rubbed his cheek, ''Why did you hit me?''
