I Can Still Become a God Even Though I Only Know How to Cast Fireball

[Everyone + Numerical Monster + Single Skill + Exponential Growth + Brain Hole + Five Fireballs + Eternal Sun + Non-Academy Flow] In the era of universal awakening, everyone can learn skills and embark on the path of becoming strong. However, Chen Qingxuan discovered that he had only awakened one skill bar and could only learn Fireball. Fortunately, he was extremely talented and directly awakened the [Evolution] talent, so he could evolve his skills just by killing monsters. What? Fireball is so useless it can't even hit anyone? I fired 3,600 shots in one second without any cooldown, thus achieving the Fireball Gatling gun path. What? Sending quickly doesn't work, you also have to be able to reach the other person? I directly modified the speed to achieve a superluminal fireball. What? Ten thousand races are attacking, and there are thousands of gods? Chen Qingxuan looked at the nuclear-level fireball technique that had been heated to one trillion degrees, and remained silent.
