The Laziest Son-In-Law in the World of Immortality

A good-for-nothing with five spiritual roots was forced to marry into a family of immortal cultivators. He originally wanted to lie down and wait for death, but was driven away by an unreliable system and a reckless sword spirit. He went from being a "waste son-in-law" to becoming the master of the three realms - not because he wanted to work hard, but because fate refused to let him.
