My Queen Pikachu's Salted Fish Companion Beast

[System + single female protagonist + beast control + daily ease] Chu Zi: In my previous life, I was a street writer. I worked hard all day coding, and eventually died from overwork. In this life, I became Pikachu, and I don't want to struggle anymore! Li Shu: In my previous life, I was the empress, and mountains and rivers collapsed in a snap. In this life, I will also go to the top of the human race and protect it! Chu Zi: As a salty Pikachu, I just want to do daily tasks, and then buy some attribute pills to upgrade into a mythical beast. Li Shu: As the first-generation SSS-level beast, you can't molest me by eating and sleeping every day. You must practice diligently and stand on the top of the human race with me, driving out alien races and guarding the human race! Wait, how come you level up faster than me? ? Chu Zi: I don't want to become stronger, genius is so annoying!
