Obtain the Crystallization of Science and Technology and Immediately Hand over the Sixth-Generation Fighter Jet

Failed to express love and committed suicide by jumping into the lake? What kind of stupidity is this! Lin Feng, who traveled through time, decided to take out the blueprints of the sixth-generation fighter jets, break them up and sell them to the country to make some money first. Why is it so cheap? Because I am from the Dragon Kingdom! School belle: "I reject your confession, so you don't have to commit suicide." Lin Feng: "Actually, the confession I made to you yesterday was just a practice session." School belle: "Are you going against the grain and chasing me?" Lin Feng: "Are you sick? After practicing with you, I went to confess to my goddess, and she agreed directly." School belle: "Uuu~ don't you like me?" Lin Feng: "Who likes a crybaby? Is there an AI girlfriend who is obedient and well-behaved?" School belle: "???" "Are you crazy about money? An AI doll is sold for hundreds of millions? Doesn't your conscience hurt?" A craftsman looked at the price of AI dolls and felt sad. Craftsmen: "Ahem, we just want to ask, is this little girl real?" This novel and its characters are purely fictitious.
