Immortality Martial Arts, Why Am I the Only One Practicing It with My Life?

Shen Congyun traveled to a world of war and chaos, and his life span was short, but he did not give up and insisted on practicing martial arts. Finally... His life span was even shorter! The appearance of a jade slip gave his life a glimmer of hope. The spirit-absorbing method: absorb the spirit of all things and feed it back to yourself. From now on, strength equals lifespan! The blue sea tide produces the secret: the sea embraces all rivers, and life is endless. From now on, lifespan is equal to strength! The Judgment of Life and Death: Life and death, reincarnation is immortal. From now on, it will last forever and everlasting! Practicing krypton skills can save lives, but I'm sorry, I have so many lives, so it's so expensive! All can be used for krypton!
