I Cultivate Immortality by Burning My Lifespan. You Break Off Our Engagement, and I'll Wipe Out Your Entire Clan

[Not Purely Invincible] [Room to Grow] [Ruthless] [Relentless Slaughter] Lin An has spent eighteen years in a fantasy world after transmigrating, only to discover that he has just one month left to live. As they say, once the cunning hare is dead, the hound is cooked. The once-brilliant genius and heir to his clan has become a useless lapdog in everyone’s eyes. His fiancée looks down on him and comes to break off their engagement. “You’re practically dead already, and you still think you can be my man? I’m here today to end this engagement!” His clan crushes him, casting him aside like trash. “You’re a dying man. You’re no longer fit to be the heir of the Lin clan!” His former brothers turn against him and kick him while he’s down. “You think you deserve to be my brother? Go die wherever you want!” Fortunately, Lin An awakens the Life-For-Power System. By killing his enemies, he can seize the years they have left to live. He can also use his lifespan to refine cultivation techniques, rapidly bringing them to perfection. Lin An: “Fine. Fine!” Lin An: “If you show me no mercy, don’t blame me for returning the favor. Today, I’ll kill until heaven and earth are turned upside down.” The clan uses him and then casts him aside? Kill! His fiancée looks down on him and breaks off their engagement? Kill! His so-called brother shows his true, vile face? Kill! If people are this brazen, then I’ll kill until no one dares to boast. If the world is this heartless, then I’ll kill until the seas run dry and the stones crumble. If they covet what is mine, then I’ll kill until no one dares to point a finger. Kill, kill, kill! I’ll kill until heaven and earth are turned upside down, until all under heaven is bright and clear. One day, Lin An climbs to the Ninth Heaven with a blade in hand and looks at the gods and Buddhas filling the sky. “I see that we are all fated to meet. Lend me the years left in your lives!”
