The Dangerous Spirit

I want to join Griffin and buy potions, but my body cannot meet the requirements without buying them. I have lost all my money and bought potions, and I have to bet on whether my heart can bear it. If I can't bear it, I will lie on the floor. I will be straight for the rest of my life. Even if I can survive the potion enhancement, there will be a command assessment later. I have no command ability? Sorry, you are not suitable for Griffin. After passing, you will become a commander to face mutant beasts...
