Urban: Other People Pay for Lottery Draws, but Mine Cost My Life?!

[Lottery + Invincible Power Fantasy + Multiple Heroines + Dungeons]

Ning Bei unexpectedly awakens a god-tier Lottery System! He can use its wheel to draw anything in the world! But here's the thing... Other people have to spend money to draw. He has to spend his life!

That's because the System uses his remaining lifespan for each draw!

“System, check how much lifespan I have left.”

“1.5 years.”

“...”

Damn, I've only got a year and a half left, and I still have to spend my life on the lottery? I'm not ready to die yet!!

Wait, I can get a certain amount of lifespan by completing System missions?

Ah Zhe...
