I Have a Gourd That Can Lead Me to Eternal Life

[No System, mortal cultivation, a female lead, slow burn]

A little gourd holds a world within. As heaven and earth undergo a cataclysmic change, strange wonders arise everywhere.

A young man travels the world alone, seeking the path to immortality and eternal life.

If you ask what an immortal is, it is someone free and carefree in this world for tens of thousands of years.
