Borrowing Life to Cultivate: I've Gone Wild with Cultivation Loans

Others cultivate through talent; I cultivate through... borrowing. Transmigrated as a waste with five-element mixed spiritual roots, facing an imminent sect tournament, I pawned myself off to the Heavenly Treasure Pavilion for a 'cultivation loan.' In half a month, I went from Qi Refining Layer 4 to Layer 6. My fellow disciples called me crazy, saying it was drinking poison to quench thirst—the compound interest could drain a Golden Core cultivator's marrow. I laughed at their conservatism; who in the modern world hasn't used credit? Worst case, I just... won't pay back. They say demonic cultivators should be ruthless, but I say they know nothing about ruthlessness. Being ruthless to enemies is nothing; being ruthless to yourself is true ruthlessness. In the sect tournament, while others treasured their lives, I spammed forbidden arts as normal attacks. Two years of lifespan? Burn it. Five years? Burn it too. Someone will extend my life anyway. They think I'm crazy, seeking death. They don't know what's lying in my spirit beast pouch. When I slaughter my way through the entire cultivation world and ascend to the throne of the demonic supreme, they'll understand: there's only one kind of person you don't mess with—someone who doesn't care about their life. And I happen to be that person. This is my path—a borrowed, stolen path of immortality that no one can take away.
