Annyeong, Jeonwoochi! Dosoolrobotdaegyeoljeon

Synopsis

After toppling a despotic ruler, Jeon Woo-chi uses an elevator to travel more than five hundred years into the future, arriving in the year 2015. There, he meets Suk and San-cho, two children skilled in martial arts, and they quickly become close. Meanwhile, his former ally turned rival, Woo Dang-tang, joins forces with the deposed king to take revenge on Jeon Woo-chi. To carry out their plan, they create a martial arts robot. Woo-chi and his new friends are caught in Woo Dang-tang's trap and locked inside a time room. The room causes them to age backward, shrinking Jeon Woo-chi into a child and taking away his abilities. Exploiting this opportunity, the king uses the robot to terrorize the people.
