I Am Gifted with Immortality, and I Have an Unlimited Contract with the Sword Girl Whose Longevity Is Broken.

Catastrophe is coming, monsters are invading, the world is digitized, and professionals become the only saviors. Su Ye, who traveled through time, awakened as an SSS-level professional sword spirit user on the first day. You can summon the top sword girl to fight for you, swing away the demon tide and slaughter the abyss with one sword! However, whether summoning Sword Girl or using Sword Girl, a lot of life will be consumed. No sword spirit user in history has ever lived beyond the age of 25. People all thought that Su Ye was finished and his life was destined to be short-lived. Little did he know, he awakened his only talent - immortality. Life span transformation: After killing monsters, you can absorb the source of life and directly transform it into your own life span! Endless Life: The life recovery speed is +300%, and the resistance to negative effects such as aging, curses, and toxins that erode the origin of life is greatly improved. Sword Lady loses her life? It's okay, I made up for it by killing two more monsters. Relying on the talent of immortality, Su Ye slaughtered all the abyss and killed all the monsters. The infinite life span is like the sea, and you can summon thousands of sword girls with just a raise of your hand. Career suicide? No! This is a throne tailor-made for him!
