I, Pikachu, the Empress's Salty Companion Beast

[System + Single Female Protagonist + Beast Control + Daily Relaxation] Chu Zi: In my previous life, I was a street writer. I worked hard coding all day long, and eventually died of fatigue. In this life, I became Pikachu! 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 systematic Pikachu, I just want to do daily tasks to gain values, and then buy some attribute pills to upgrade into a mythical beast. Li Shu: As the first-generation SSS-level beast, you cannot eat and sleep 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 did you make yourself invincible? Chu Zi: I don't want to become stronger, I just want to enjoy life!
