Chinese tightrope artist Aisikaier Wubulikaisimu has completed a death-defying challenge by walking back and forth between two cliffs with a drop of over 300 meters below him, while being partly blindfolded on Sunday. It took him about 15 minutes to walk across the wire from one side of the valley to the other in southwest China’s Yunnan Province. Wubulikaisimu currently holds the record for the world's fastest high-wire walk, as well as for the steepest inclined wire walk.
