When it came to clearing the loose rocks from the sheer cliff face, Ren He took on the task himself. At this point, he was slowly lowered down the cliff by a safety rope to become familiar with every rock on the surface.
Personally clearing the climb meant that he would understand the challenges he would encounter during the free solo climb.
Moreover, with his exceptional memory, just one climb would be enough for him to perfectly remember the structure of the cliff face, forming it all in his mind, ensuring he wouldn't make any wrong choices.
But still, the biggest problem remained: there were too few footholds on this cliff face. Ren He furrowed his brows; in some places, it was difficult to find a hold, the gaps barely wide enough for a fingertip.
Why is it always emphasized in the field of free solo climbing that only vertical cliff faces represent a higher degree of difficulty?
