Something's Terribly Wrong With My Experience Bar

After the apocalypse, human consciousness was transferred into the game world.
It was a fresh start. A new civilization, a new society, a new order...
Lu Qingge entered the game world and spent a whole year without even completing the beginner's tutorial.
He remained at Level 1, unchanged, and even achieved the hidden achievement of "King of Idlers" because of it.
It turned out that without an "experience bar" in the game interface, he couldn't level up at all.
Not only that, he didn't have a "profession" or a skill tree... He was a genuinely unlucky player.
Fortunately, there was always a way when there seemed to be none. He was surprised to discover that... everything except himself could level up!
So, he started randomly allocating skill points to the skill tree with his experience points...
A reporter asked, "You're still at Level 1 right now, but how did you become the world's top player?"
Lu Qingge replied, "Because of perseverance and hard work."
The reporter continued, "Then how did you defeat the abyssal demon king at the catastrophe level?"
Lu Qingge pulled out a Level 8888888 greatsword. "With this."
Netizen exclaimed, "You're talking nonsense! The abyssal demon king is immune to physical damage!"
Lu Qingge casually threw a Level 9999999 fireball. "And this."
In the next moment, the world fell silent.
