Luo Xuan traveled through Doupo Cangqiong and obtained the Altar of the Heavens. As long as he sacrificed something of sufficient value, he could exchange for the desired items. After ordinary people get this ability, they will definitely want to obtain the Supreme Bone, the Ancient Saint Body, the Chaos Body and other invincible physiques, but Luo Xuan disdains it. Fantasy things are indeed good, but that's all. To really reach the sky in one step, you still have to look at the good things in the second dimension. The Kryptonian physique that becomes stronger when exposed to the sun, the Super Saiyan physique that constantly breaks through in battle, the hurricane gyro that can destroy the multiverse universe... All of these can make people reach the sky in one step without any side effects. It's just fantasy, so don't bother.
