This is the story of a carefree young man from the 21st century who transmigrates to another world because of a mysterious ancient sword, and goes on living another "carefree" and "wonderful" life.
Legend of the Ancient Sword: In primordial times, Heaven and Earth were as chaotic as an unhatched egg. Pangu was born within it, unable to bear the darkness and the air, almost frozen in place. In his haste, he pulled out one of his teeth and transformed it into a mighty divine axe, hoping to cleave the darkness and usher in the light. But in his impatience, he used too much force and accidentally knocked out another tooth... During eighteen thousand years of darkness, this tooth silently accompanied Pangu as he tirelessly worked to split the darkness. It suddenly gained a spirit and transformed into a divine sword, helping Pangu's axe cleave apart chaos and create Heaven and Earth.
Afterward, the divine sword absorbed the essence of the sun and moon and the spiritual energy of Heaven and Earth, then vanished into the bustling mortal world, waiting to grant a person of destiny a journey across time and space.
