My F-Level Talent Has No Upper Limit

In the era of national awakening, the talent awakened at the age of eighteen determines the destiny of life. Some people have awakened the A-level talent "Fire Demon Body" and are eagerly competed by prestigious schools; some have awakened the S-level talent "Ice Phoenix Sword Heart" and are destined to reach the pinnacle of martial arts. But Jiang Chen only awakened an F-level talent that was ridiculed by everyone - increased proficiency. Everyone said he was useless. The teacher felt sorry for him, his classmates laughed at him, the genius looked down upon him, and even his qualification for the martial arts examination became a joke. Until Jiang Chen discovered that his talent was not an ordinary increase in proficiency at all, but - any skill could be infinitely upgraded and evolved, with no upper limit! The basic boxing technique evolved into the Dragon Elephant Prison Suppressing Boxing. Basic footwork has evolved into a world away from home. Basic meditation, evolved into ancient star god contemplation ideas. While others were competing for advanced skills, Jiang Chen silently practiced the most common basic martial arts into forbidden magical skills. Many years later, aliens came and all races invaded. When everyone was in despair, Jiang Chen took a step forward. "Who said an F-level talent can't be invincible?"
