Douluo Continent: Idle Immortal

(This book has been cut; please read with caution.) My name is Yang Tian, ​​and I'm a transmigrator. Luckily, I transmigrated into the Broken Clan; unfortunately, I transmigrated a bit too early, as the Spirit Hall will be attacking us in fifteen years. Fortunately, I have an idle cultivation system. After resolving the initial crises, I realized I had become the strongest person on the continent.
