求翻译：只见他辛苦的蹲在地上画着，不时用手指在地上摩擦晕染，双手漆黑，全然不顾地面摩擦的疼痛，也不顾气温的炎热，专心的画着。是什么意思？

I saw him squatting on the ground hard painted, often with a finger on the ground friction washes his hands dark, completely ignoring the pain of friction surface, but also regardless of the temperature of the hot focus of the painted.
