Switch and Become Invincible

After the protagonist Lin Fan drinks the wrong "Internet celebrity transgender drink", he awakens the ability to switch between men and women without CD and in seconds - the male phase "Lin Fan" is the "physical god of war", he can punch through the wall with one punch, and he can also hit with a punch; the female phase "Lin Wan" is the "charming bug", which can turn the enemy into a fanboy/fangirl in the blink of an eye, and can make the opponent take the initiative to send resources by speaking a word. You don't need to use your brain to make strategies. Switching gender is equivalent to becoming invincible. If you can't beat it, switch gender. If you want, switch gender. The system only sends out "pleasure tasks". After completing them, you will be given a "gender enhancement package" (males add strength, females add charm). It's so cool that you can fly.
