I Worked Hard to Level Up, but I Was Invincible at the Beginning.

Traveling through the world of Xianxia, ​​Xu Ang got a ball of light. As long as he breaks it and gets the 18,000 points of source energy inside, he will be invincible in this world. But Xu Ang spent a lot of effort and only broke the skin of the light ball to get a mere point of source energy, but it was of no use. The light ball was so hard that Xu Ang, who thought he could only smash it step by step, accidentally used this little bit of power to knock down the world's top experts one by one. PS: Invincible flow at the beginning, no diversion, no brainwashing.
