Lin Tian transmigrates into the dimensional universe of Jackie Chan Adventures and becomes the demon Xiao Feng. He sets himself two goals.
First, disguise himself as a human and, under the name Lin Tian, infiltrate Section 13 to find a way back to his original dimensional universe.
Second, keep a low profile at all costs. He must not let anyone discover that he is a demon, or he will be sealed away or contained.
What he never expected was that Xiaoyu, Jackie Chan's niece, would grow up to become a captain at Section 13 and take an immediate liking to Lin Tian, then just a lowly errand boy. She transfers him to her team as a field agent.
And so Lin Tian, a demonic antagonist, embarks on righteous adventures under Xiaoyu's leadership.
Even more surprising, soon after Lin Tian becomes Xiaoyu's subordinate, the mission he takes on turns out to involve demons. He is drawn into the secret power struggles of this mysterious race.
Magic, technology, ancient secrets, and multiple universes: the keys to everything are in Lin Tian's hands. With Xiaoyu, Uncle, and the others getting involved, Lin Tian finally touches the ultimate truth of the demons. Though he is a demon himself, he also embarks on a path to godhood, becoming a rare kind of deity. (The path to godhood will take quite a while to develop.)
How stupid!!
