In the battlefield of all races, I am still invincible as an F-class hero

【Not a saint + single heroine + decisive killing + survival】
Gu Shaoshang was told that he was dead just after crossing. He
didn’t have time to grieve, and the next second he was summoned to the battlefield of all races and became the initial hero of a pink-haired loli.
Hero qualification… F-level?
Tens of billions of humans on Blue Star were selected to join the battlefield of all races, but Lin Youyu was unlucky enough to randomly get an initial hero with F-level qualification.
Lin Youyu: It’s so spicy! The game started with a collapse of the sky!
Gu Shaoshang: It’s killing me! Fortunately, I have a cheat!
Other heroes only have one talent, but Gu Shaoshang found that he has two.
【Talent ability (hidden): Endless talent】
【Endless talent (???): Each time you level up, your own talent level +1! Get a new talent every 10 levels! 】
Gu Shaoshang: Who said that F-level heroes are cannon fodder?
Lin Youyu: Go for it~! Brother Gu, kill them! Hehehehe!!!
Ten thousand races strong: My SSR-qualified hero was killed by a F-level hero with one sword? You told me you didn’t open it?
