Future Knowledge: My Saiyan Survival Cheat

Reborn on Planet Vegeta as a low-level Saiyan, my future was already decided: doom. Five years later, the terrifying God of Destruction Beerus arrived, a clear sign. Frieza's galactic tyranny was about to wipe out my entire race, my home world, and me. Unlike my brethren, I wasn't born a prodigy, nor did I have a magical system. My only cheat was the knowledge of a past life—every twist, every power-up, every catastrophic event of the Dragon Ball universe. With this forbidden foresight, I secretly honed my Qi, suppressing my true combat power to remain hidden from watchful scouters. Now, the countdown to annihilation has begun. Can I leverage this knowledge and my hidden strength to escape the doomed planet, or will my efforts to save myself and maybe a few others trigger an even greater, unpredicted disaster?
