The World Mutates, and I Become the Strongest

(Global mutation, modern high-martial arts, another world, System-based, hunters, secret-realm exploration.) "Ding! Global mutation activated. System awakened!"

In 2050, a continent from another world appeared in the Pacific Ocean. Windows appeared before the eyes of the lucky humans: some awakened the power of fire, others gained control over rainwater, while I awakened a supposedly "useless" lightning ability.

After being tricked by a shady merchant into a secret realm for three years, I emerged as the strongest of all.
