I Get the Longevity System from the Start

After transmigrating to another world, Ye Changsheng got the Longevity System from the start.

"Senior Brother, this is bad! The enemy is attacking!"

"Don't panic. I'll burn a few hundred years of my lifespan, then fight them."

"Brother, someone stole your wife!"

"Don't worry. I'll burn a few hundred years of my lifespan, then fight them."

And so Ye Changsheng set out on the path to invincibility by burning through his lifespan.
