Reverse Awakening: I Can Copy All Abilities

My name is Ling Chen, 18 years old, an orphan. On the day of awakening, everyone awakened their superpowers - fire, thunder, and speed. Only I was judged to have "no attributes" and became the laughing stock of the whole school. But they don't know that my ability is an "absolute copy" with an explosion rate of one billionth: as long as I'm within one meter, I can learn any superpower. The price is that each time you learn one, it will cool down for seven days. From campus slaps to dungeon fights, from the mutant camp to the mutant conspiracy, I used other people's abilities to go my own way. The most useless person to wake up at the beginning? Excuse me. Your powers are all mine.
