Kain wasn't originally a superstitious individual, but after transmigrating into a fantasy world and literally reading about skills, items, and spiritual creatures that can influence luck, that changed.
Therefore, before spinning the wheel, Kain exited the System and partook in every superstition he could think of, both from this world and his previous one.
He first began with throwing a pinch of salt, taken from the seasoning rack in his space ring, over his shoulder. Then he lit 4 candles in each cardinal direction of the room.
Then he meticulously washed his body to scrub off any bad luck. He knocked on his wooden bedpost 3 times, and finally placed a dried four-leaf clover he'd found at the orphanage years ago on his chest before lying down and re-entering the Laboratory.
"Okay! I'm ready!"
He pressed the button to spin the wheel while crossing his fingers for good measure.
