my first m4m buddy hook up story

What if a power to level up or upgrade everything—your way of living, battle skills, military prowess, etc.—but this power is limited to your Eldritch tribe. Would you expand your tribe to rise above all adversaries, would you use it to gain more personal power or use it to toy with everyone? Lyerin wanted nothing more than peace on himself, but all he had was regret. He possessed a secret ability that allowed him to quickly excel at anything he chose, but he could only use it once. While others had to spend a long time to reach higher levels or master new skills, he only needed to complete a simple, specific task to level up. However, he had already used this ability to count a specific number of sand grains to save his own life. After that, his existence became a living hell. One day, he was unexpectedly sent back in time, where he would witness numbers appearing in the sky, signaling the end of the world again—an apocalypse he despised the most! But Lyerin realized he could use his ability once more, this time on a certain group of people. A TRIBE! ``` [ Ding! ] [ You have chosen to level up knife slash!
