Practice? I Became a Fairy by Lending Money!

I, Lu Yu, am the last conscience in the world of immortality! After all, others are taking away your skills and opportunities, but this shopkeeper will directly "give" them to you! Sweet words before the loan: "Don't panic, fellow Taoist! Take this bottle of magic elixir first. Interest? It's only 30%~" After the loan, he turned his face: "What? Can't you pay it back? Then I'll take 90% of your Transparent Sword Heart, but that's not too much, right?" From martial arts and magical weapons to cave thunder tribulations, there's nothing you can't imagine, and there's nothing I wouldn't dare lend you! Remember: Who is the warmest on the road to immortality? Boss Lu in the foundation!
