Is “Gong Gong, after failing to contend with Zhuan Xu for the throne, angrily struck Mount Buzhou, causing the sky to tilt northwest.” true?

The 'Huainanzi·Astronomical Treatise' records that after Gong Gong failed in his struggle with Zhuan Xu for the throne, he angrily struck Mount Buzhou, causing the 'heavenly pillar to break and the earth's cords to snap', leading to the grand cosmic origin myth of the sky tilting northwest and the earth sinking southeast. Early 'Classic of Mountains and Seas' records him as a water god, but does not explicitly mention the episode of his angry strike on Mount Buzhou and the resulting cosmic upheaval. This is a systematized and philosophical interpretation by scholars after the Han dynasty, not a pre-Qin historical fact.
