I'm Only One and a Half Years Old, and My Mother Is the Zombie King

I'm only one and a half years old, so I can't speak well, but my mother is the zombie king. While others are running for their lives in the last days, I will be served as the crown prince by all the zombies in the city. Until one day, a group of people snatched me away, saying they wanted to "save the hope of mankind." My mother was anxious and came to the city with millions of zombies.
