Free-climbing is probably one of the most unsafe things you could ever do, which is probably the same rationale given by anyone who actually tries it in the first place. Vadim Makhorov and Vitaliy Raskalov, who together call themselves On the Roofs, are exactly that type of person.
The two traveled to Shenzen, China, recently and scaled the 2,165-foot Ping An International Finance Centre, a 115-story skyscraper that is expected to be the world's fourth-tallest building when it's completed in 2016.
Yep, it's not even completed yet. The daredevils had to break through a lock at one point on their ascent to even get to the top. Check out their ridiculous climb in the video above.
