At the training base of the Marine Corps Blue Shark Special Forces Group, the four specially recruited team members: Doctor, History, Naughty, and Hammer, experienced the superhumanly rigorous training and screening of the Special Operations Group and became qualified special operations members; however, in the eyes of the veteran scouts who have experienced the battlefield, they are still "student soldiers" and "young master soldiers."
In a battle to hunt down the pirate "Carrot", they volunteered. In the process of tracking the pirates, they followed the pirates into the time and space shuttle manufactured during the Japanese war, traveled through time and space, and came to the Ming Dynasty.
Facing the complex battlefield environment, they relied on their rich knowledge and excellent military qualities to fight Japanese pirates and ninjas, and wander among officers and soldiers, pirates and bandits.
They had a wonderful showdown with the "Carrot" pirate group who wanted to change history and dominate the world; at the same time, they also experienced the test of power, love and mission.
