Five-Year-Old Cute Baby Takes His Mother to Seek Immortality and Treasure Hunt

My five-year-old son dug out ancient artifacts with a toy shovel and took me through other worlds to hunt for treasures. A mysterious group comes to hunt down the family. The killer disguises himself as a parent at the parent-teacher meeting, and the son uses a magical weapon to expose him on the spot. The teacher asked me how to explain, and I just wanted to say: Let my son save his life first!
