Good Grief! You Practice Demonic Arts, but I'm the One Who Bears the Backlash?

On the Tianxuan Continent, immortals and demons contend for the sliver of opportunity that will allow them to ascend. In the Great Xia Kingdom of the Southern Wilderness, Jiang Xuan arrives with the Kunlun Mirror, a rare treasure that can transfer any side effect he suffers to someone else. The Bloodburst Pill is remarkably effective for cultivation, but it shortens your lifespan? No problem. I’ll take two pounds to start. Bloodburst pills with liquor, the more you drink, the better! Jiang Xuan takes pills to boost his cultivation, while his enemies one by one exhaust their lifespans and grow old before their time. The Yin-Yang Demonic Art is incredibly powerful, but it turns you into neither man nor woman? Meanwhile, his enemies who cultivate pure Yang techniques discover that their powers have been crippled! As for the Heavenly Demon Disintegration and the Nine Nether Demon Saber, I hear their side effects are pretty brutal? That’s exactly what I want. If they weren’t brutal, I wouldn’t practice them! Hundreds and thousands of years later, on the battlefield between the righteous and demonic factions, the righteous elders surround Jiang Xuan as he activates the Myriad Ages Demonic Tribulation Heavenly Art. The righteous elders look at him with regret. “Once the Myriad Ages Demonic Tribulation begins, your cultivation stops and you die.” “What a pity. A peerless demonic prodigy, reduced to ashes just like that.” An hour later, Jiang Xuan looks at the righteous elders, now reduced to ashes, and sighs. “Looks like the version has changed. Mine is the all-new Myriad Ages Demonic Tribulation.” “When has the demonic path ever cared about playing fair? I practice the demonic art, you bear the backlash. That’s reasonable, right?”
