Zhang Huan, the 39-year-old special forces king, sacrificed his life to protect his teammates and was reborn into the body of a three-year-old baby - soft and cute with short legs and a milky voice, but his soul contains the core of a soldier king as an "iron-bone old father". While he was using his three-year-old body and his brain as a soldier to do things in the kindergarten, he relied on the vague memories of his past life to change his destiny. The contrast between the cute appearance and the hard-core soul makes you laugh until you cry, and the warmth of saving your parents touches your heart. There are both the famous funny scene of "a child pretending to be an adult" and the healing moment of "finally protecting the one you love most". It is a refreshing novel that can make you cry when you laugh, and laugh again when you cry.
