I Grow Stronger by Courting Death, Starting by Provoking the Saintess

Ruthless + Hilarious Antics + Wei Wu's Legacy (His personality will change once he becomes powerful)

Lucky enough to arrive in a fantasy world, Lu Changsheng is nevertheless born without a spiritual root. However, he does have a rather useless Peace System, which makes him immune to any move that could put his life in danger. To keep his secret from getting out and attracting unwanted attention, Lu Changsheng has no choice but to live in seclusion. Then he unexpectedly encounters a battle involving a saintess and gains the ability to pull pranks. From then on, he sets out on a one-way road of mischief.
