This is a floating continent called the Kingdom of Spring. On this continent, not only is the weather like spring all year round, but there are also some people who will acquire a piece of armor as their "spiritual power" increases. These special people are called "armor warriors". And when a person successfully obtains the upper limit of seven pieces of armor, he is called the "Extreme Armor".
The protagonist of the story, Yan Yu, originally lived with his sister in a border town in the Kingdom of Spring, but suddenly one day his sister left without saying goodbye. On his sister's 12th birthday, Yan Yu went out alone to buy daily necessities for her sister. When he came home, he saw a mess on the ground and many signs of fighting. Yan Yu frantically searched for his sister in the entire town for a month to no avail, so he decided to embark on a journey to participate in the "Armor Warrior Martial Arts Conference" held by the Kingdom of Spring and the Kingdom of Autumn.
He wanted to believe that his sister, who was an "Armor Warrior", would definitely participate.
No matter how the story develops, it will gradually reveal the whirlpool of Yan Yu and his sister Yan Huan's life experience, as well as the invisible network organized by major forces and forces from other countries.
