Lu Zhaoyan, the youngest professor of physics at Qingbei University, the North Star of academic circles, aloof and ascetic, is the flower of the high mountains that cannot be desecrated in the minds of teachers and students at the school. Lin Xiaoxiao, a sophomore in the Department of Physics, is obsessed with Professor Lu's beauty every day, and is on the verge of failing the exam. Everyone thought that this was just a campus comedy about "a scumbag falling in love with a god of learning". Until a crisis that affects the global network quietly comes, the school computer room is destroyed, and the national key laboratory is in emergency. Lin Xiaoxiao, whom everyone regarded as "silly and sweet", was personally invited to the control center by the head of the mysterious department. She held the lollipop in her mouth, and her fingertips flew like butterflies on the keyboard. Ten minutes later, the dead end created by the world's top hacker organization collapsed. She rubbed her sleepy eyes and walked out of the control center, and bumped into Lu Zhaoyan, who had rushed over after hearing the news with a solemn look on his face. "Professor Lu," she raised a harmless smile and shook the candy in her hand, "The crisis has been resolved. Can we focus on this final exam...?" Lu Zhaoyan looked at her with eyes as deep as an abyss. Later, an underground auction turned out to be strange, and the national treasure-level cultural relics were about to be lost overseas. Lu Zhaoyan appeared as a mysterious buyer, but he saw Lin Xiaoxiao dressed in a gorgeous cheongsam and lazily holding up a sign. The price soared to one billion, shocking the audience. He pushed aside the crowd, cornered her in an uninhabited corner, his warm breath sprayed in her ears, and his voice was hoarse: "Lin Xiaoxiao, how many secrets do you have that I don't know?" The girl blinked her clear and innocent eyes, drew circles on his chest with her fingertips, and said softly: "Professor Lu, each other. Your vest... Seems like it can't cover it anymore.
