Live Long Enough, and Even Immortals Become Dog Food

Tang Feng transmigrates to a fantasy world and gains the Longevity System.

The System’s only function is to extend his lifespan.

Run three kilometers, burn 250 calories, and gain more life.

Throw a punch, expend 1.87 joules, and gain more life.

“Anyone who crosses Tang Feng will be killed, no matter how long it takes.”

One day, a deity enrages Tang Feng.

A thousand years later, his backyard is full of fairies.

As the years pass and all his enemies die, Tang Feng returns, still a young man!
