I'm a Casual Cultivator, so It's Reasonable for Me to Survive Until I Ascend, Right?

[Mortal flow + traditional cultivation + Taoism + decisive killing + no female protagonist] Modern man Ning Ye accidentally traveled through the world of cultivation and became a mortal. By coincidence, we can walk on the path to immortality and have a glimpse of immortality. The family is in trouble, parents are buried, and they are mad with hatred, but they accidentally find the supreme treasure. With the treasure in hand, it can cut off cause and effect and hide its traces, making it difficult to find in the heavens; it can also reverse the origin of all things and return all transformations to their origin. Ning Ye, who is well versed in the true meaning of Taoism, appears to be low-key and cowardly, working as a mediocre cultivator, but secretly has ruthless thoughts and plans every step of the way, just like a murderous god and evil ghost. For a hundred years, the name of Old Ghost Ning shocked the five regions! Using the treasure to avoid disaster, he lurked in the cunning and deceitful world of immortality, quietly harvesting opportunities, and using his righteous methods, he finally found a way to ascend to immortality...
