Wu Yongning had become a web celebrity in China for his daring daredevil stunts.

The 26-year-old posted more than 300 videos which showed him tiptoeing along skyscraper ledges and/or doing pull-ups as he hung from the sides of tall buildings.

He died on November 8th, attempting a $15,000 pull up challenge on the side of a 62 story building.  His death was confirmed this weekend by his girlfriend after fans had been speculating on why he hadn't put up any new content.

Here's a video of his final stunt, which some may find disturbing. 

Here's a collection of his more successful stunts.

RIP.
