My Memory Is Fairy Ruins

After traveling to the world of immortality for fifteen years, I always thought that I was an indigenous orphan with no cheats. It wasn't until the night when my whole family was massacred by a mysterious cultivator that I awakened to the memory of my past life when I was on the verge of death. It turns out that I came with a "library of all heavens", which contains the Taoist treasures of all realms. What's even more terrifying is that I gradually discovered that my parents and the enemies who massacred the village were actually the same group of "reincarnators". This time, I hold the Immortal Code of All Realms in my left hand, and the Cause and Effect of Destruction in my right hand. Using myself as bait, I vow to fish out the biggest mastermind in all the worlds!
