I'm Alone Forever

It is said that in ancient times, there were double coffins. There are thousands of races and heroes vying for hegemony, but only one race or one person can be alone forever! Is it the fantasy of a reborn person pursuing eternity? Or a person who practices martial arts, cultivates immortality, and becomes a god in all the worlds? Tempered golden bird, red lotus sword, flowers in the mirror... Canglan has been the only one in this world for a lifetime. On the day he becomes a god, all the immortals will die!
