Crazy Bull steals a bike

The Japanese occupied China and the regularly shot the Chinese for any reason. They used chinese for manual labor regularly pretty much like dogs. China the country was weak and the people, disorganized and without proper weaponry to really push the Japanese out easilt.
It was this time period that Crazy Bull lived.
Crazy Bull was born a fearless and naturally strong beast of a man. He caught poisonous snakes grabbing them as if they weren't even snakes, never hesitating. His face blank and with little emotion or reaction. His Kung fu was half and half but
he made up for that in strength and ferocity. When he fought with a stick using the basic moves he had he would growl like some sort of cross between a bear and a wolf swinging the stick so that nobody could get near him. Supernaturally strong and terrifying, what skilled fighter would really want to fight him?
His fearlessness went beyond his power over people, his strength, bravery and even reason.

He was sqatting with one of his friends by the river looking at fish when his mentioned he needed a bike to ride to town but there was no way he could get one.

"Oh you need a bike?" said Crazy Bull. "I know where to get one." and walked away.
He went to where some Japanese were overseeing Chinese workers. They noticed him walking up nonchalantly and with authority.
He walked right over to where the Japanese Soldier was standing next to his bicycle.
The Japanese soldier watched this man calmly walk over and take the bicycle without a word and walk back with it. The Japanese soldier, though it was his bicycle , hesitated but then said nothing, neither did any of the other Japanese. After all, the Soldier who was the owner of the bike said nothing so, uhe must know what's going on. No Chinese would just take a bike or dare even look at a Japanese wrong or he would be instantly shot.
This Chinese must have been told by a higher officer to come over here and get the bike for him. This is what they said within themselves as Crazy bull walked past them with the bicyle as if it was his. He walked all the way back to the village like this, without being bothered.

Crazy Bull lived to around his 60's.
When he died so many people had been amazed by his presence that those in power, now the Communists, did an autopsy and opened him up, finding that his spine was different than a normal person's spine. Thicker and formed in a different shape.
