Everyone: I Can Upgrade Infinitely

In the era of job transfer for all people, rank is justice and talent determines destiny. Transformed into an S-level professional hero, with F-level talents, God rewards those who work hard. But so what! While you are still worrying about breaking through the level bottleneck, I have already upgraded the master level skills to myth. When you laugh at me for being the weakest hero, I am already standing at a height that you cannot look up to. If you work hard, you can really do anything you want. This story is purely fictitious and any similarity is purely coincidental.
