Playing the Immortal in a Dogblood Novel [Quick Transmigration]

After Xu Yulin died, she met a ball that called itself the System.

The System listed several missions: an immortal princess repeatedly betrayed by a scumbag but still forgiving him; a fox woman tormented by a wicked young master all her life and forced to bear his child at the cost of her own lifespan; a national preceptor maliciously framed and cast down into the mortal world...

The immortals stepped in, helping them break free from the villains and start their lives anew.

The protagonist is General Lin, a supporting character with a soul from another work, A Fleeting Light. Since she had a wife and child in life, I decided not to tag this as no romance after careful consideration. This story will not include any romantic pairings involving the protagonist.

Theme: Eat, sleep, and beat up scumbags.
