[Longevity + Witty Humor + Powerful Protagonist + Survival First]
Li Xian transmigrates to a cultivation world and awakens the Longevity System. Though the System grants him longevity, it can't make him immortal. He has to keep improving himself to gain the strength to take risks without dying.
Whenever he interacts with living beings, the System gives him experience points, which he can exchange for physical strength, spiritual energy, comprehension, and buff points.
Knowing that the cultivation world is full of danger, where the slightest mistake can mean death and the end of his path, Li Xian takes survival first as his guiding principle and cultivates diligently, gradually growing stronger.
With his survivalist nature, he safely makes it through the great upheaval in the cultivation world, crossing several cultivation eras and eventually becoming a big shot.
Along the way, he travels through the mortal world, the cultivation world, and the Immortal Realm, experiencing all the world's ups and downs, the helplessness of the Immortal Realm, and the loneliness of eternal life. He has had moments of passion, moments of weariness, and even moments when he wanted to end his endless life. But the universe has no end, and neither does longevity. What choice will he make?
The writing of this book is not bad, and the protagonist is not blindly cultivating machines, but the plot is a bit old-fashioned. The characters seem to act in a predetermined trajectory, but there are no obvious poisonous points, so it is generally good.
