Lasting Life from the Start: AFK Mortal Martial Arts Automatically Cultivates Immortality

Xianxia · Slow-paced power fantasy · System · Longevity · Cautious protagonist · Single female lead

Shen Yuan transmigrates into a cultivation world and, right at the start, a demon calamity massacres his village, leaving him a six-year-old orphan.

A hellish opening.

Fortunately, after deciding to train in martial arts, he awakens the Longevity Idle Cultivation System. His lifespan is limitless, and all his cultivation methods and techniques can be trained automatically while idle.

Shen Yuan decides to keep a low profile first, grow stronger through idle cultivation, and slaughter demons to avenge himself.

But before his immortal path can stabilize, trouble arrives first.

His stunning master, Xie Qingxian, afflicted with the Bone-Eroding Entwined Passion Curse, pushes him down...

After one night, Shen Yuan is dumbfounded.

Becoming a cultivation cauldron and letting his master devour his lifespan can help raise her cultivation?

And his master is gradually developing a taste for it and becoming addicted?

After regaining clarity, Xie Qingxian goes from guilt to being deeply in love.

She wants to get close to Shen Yuan, yet fears harming his lifespan.

To that, Shen Yuan only wants to say: Master, this disciple's lifespan is infinite, so do as you like! But can we switch things around so I'm the one taking the initiative? Getting treated like an all-you-can-eat buffet every day is really too much!

Xie Qingxian can't understand it either.

Why does this disciple's lifespan seem bottomless, impossible to exhaust?

...

Enemies and sect conflicts come one after another.

To protect himself and his master,

Shen Yuan can only quietly choose to idle-train those forbidden secret arts that burn lifespan.

When a powerful enemy descends and Xie Qingxian is powerless to stop them,

Shen Yuan lets out a soft laugh amid the flames of war and silently says in his heart: Burn 100,000 years of lifespan!

In an instant,

gods and demons retreat, and the universe is shaken.

...

Many years later,

Shen Yuan stands atop the peak of all immortals, as countless immortal beings tremble and bow before him.
