Having Reincarnated a Million Times I Won’t Let My Guard Down Even in a Peaceful World

Rex is a reincarnator who has lived through a million lives.
Having survived in harsh worlds up until now, he believed that this new world would be no different.
Therefore, no matter how much praise he received, he remained vigilant, always preparing for the ‘enemy’ that could appear at any moment, determined to live out his natural lifespan this time.
However, this world was genuinely peaceful, there was no ‘enemy,’ and Rex was truly a genius.
While those around him praised his abilities and adored him, he continued to believe there was some ‘hidden agenda.’
