Oh No! I've Awakened the Wellness System?

[Urban setting with a fantasy cultivation system. The early chapters get pretty rough, so don't read if that's not for you!]

Lin Luo discovers that he has transmigrated and awakened a Health and Wellness System.

"What!? What kind of lousy System is this?

It's actually telling me to take kidney supplements? What good will that do?!

I'm done for. My life... is over!"

But he never expected that, years later...

"Demon Venerable? He looks like he has kidney deficiency. I should be able to beat him!"

"Dao Ancestor? Still looks weak..."

"Demon Emperor! Take my sword!"

"Ghost Emperor, your kidneys... Hm? Wait! Do ghosts even have kidneys? Fellow Daoist, don't be afraid. Let me dissect you!"

Until... that dreamlike voice sounded once more.
