Starting with No Spiritual Roots, He Became the First Person to Cultivate Immortality

(Traditional immortal cultivation + slow-heat upgrade + innate opportunity + Lao Liu + decisive killing + mortal + devouring cultivation + ten thousand soul flags) Bring yourself into this world with your heart, and write about the difficulty of this spiritual path from a mortal perspective. It may not be very satisfying, but it will definitely be in line with human nature in reality and make it more real. Countless days of near-death, days of licking blood on the tip of a knife, the path of spiritual practice is destined to be lonely. Why did you risk your life to reach the starting point when you were born? Why would you step on someone else's famous family?
