Single mother Lin Niannian lives a hard life with her three-year-old son Shen Ye, but she is humiliated by the wealthy Shen family. She didn't expect that her son Shen Ye could blow up the president's limited edition sports car with a milk bottle - it turned out that Shen Ye was the reincarnation of the God of War, and the CEO Shen Moyuan who abandoned her was the God of War himself.
In order to protect his mother and son, Shen Moyuan once exploded the power of the God of War and sealed his memory. Now that the King of Shadows has come to Earth, the family of three is forced to fight side by side. With the help of the Grumpy System, Shen Ye's milk bottle can transform into a rocket launcher, a war hammer, and even the ultimate form of "Star Guardian". They discovered that Lin Niannian was actually a contractor of the God of War, and had sealed his dark side with his own hands back then.
During the final battle, Lin Niannian adopted the dark side personality and joined forces with Shen Moyuan, Shen Ye and his son to kill the King of Shadows. After the war, a family of three discovered a new space-time rift in Antarctica, and the Ares signal from another universe came. The Bottle God of War begins a new journey.
