Fifty years ago, Dragon City transmigrated  to the Other World. Alone in the world, they lifted the banner of  Earth’s civilization and fought against the terrifying forces of the  Other World.
    And in the end, Dragon City was destroyed.
    Then, Meng Chao was reborn after Dragon City was destroyed, and he  returned to the time fifty years after Dragon City transmigrated to the  Other World. But he was not alone, he returned with a system named  Kindling, who told him that he can become stronger if he contributed to  society.
    So Meng Chao swore that he would become stronger. In the beginning,  he only wanted to make small contributions to the society by teaching  them technology, martial arts, and skills from the future, and in the  end, everything snowballed from there, and he found that… Earthlings  were really insane.
