The story takes place in 2017. The armed forces "pioneers" transformed by bionic technology have already infiltrated all aspects of the national security network. Liuli (voiced by Shan Xin) is a third-generation pioneer. Because of the overload of the body, there is only one year left. On this occasion, Liuli received a special task to protect a man named Sun Haoxuan (voiced by Dingdang). Sun Haoxuan is a genius in electronic equipment and has an extraordinary self-healing ability, which implies his special identity. Sun Haoxuan likes senior Bai Hua (voiced by Luo Rufei), but Bai Hua's true identity is the fifth-generation pioneer. She was instructed by Dr. White to approach Sun Haoxuan for a certain mission. The encounter between Liuli and Sun Haoxuan completely changed the fate of the two and the future of the world. In the process, the indifferent and introverted Liuli gradually fell in love with the upright and kind Sun Haoxuan, and finally used this love to save Sun Haoxuan who was in danger.
