My Skill Levels Double Every Day, Letting Me Crush Everything with an Army

[Power Fantasy] [Invincible] [Decisive and Ruthless] [Never Holds Back His Level] The day his younger sister awakened the legendary class [Chrono Star Curse Mage], she disappeared. Before their parents could report it, they were gravely injured and fell unconscious. Two strangers soon appeared around Su Chen, watching him with undisguised murderous intent. He was only the most ordinary kind of [Summoner], with just two starting skills: Fire Element Summoning and Wind Element Summoning. Fortunately, the System activated: the level of every skill doubled each day, with no limit. On day one, he summoned a palm-sized fire wisp that could barely stay afloat. The watchers sneered. On day three, a three-meter-tall lava behemoth tore through the summoning circle and smashed half a room flat with one punch. The watchers stumbled back in terror. On day ten, a hundred Flame Demons and Wind Falcons formed ranks across the sky, and the whole city looked up in awe. On day thirty, an army of three thousand Fire Elementals descended. The two watchers were swallowed by a tide of summoned beasts, leaving not a trace of their remains. Su Chen stepped out of his home over the ashes. “I’m done waiting.” On day one hundred, an army of a million elementals blotted out the sky as he crushed three shadow organizations one after another. On day three hundred and sixty-five, his summoned creatures numbered over a billion. He tore open a rift in time and summoned his past and future selves to arrive at once, intercepting every chosen of the gods just before his sister disappeared. “You dared lay a hand on my sister? You’re surrounded by a billion versions of me.” On day one thousand, he sat at the end of time and space, then snapped his fingers at the trembling Supreme Will. Summoning circles filled the Myriad Worlds. “Want to fight? Clear out my troops first.”
