[Being in Cao's camp and being in Han's heart + high-tech crushing + multiple female protagonists + patriotic passion] "Su Chen, hand over the 2nm lithography machine parameters, otherwise you won't be able to leave this laboratory!" Traveling through the Sakura Country, Su Chen was betrayed by his girlfriend at the beginning, his limbs were tied, and he faced a life-or-death decision. In a critical moment, the [Duozi Duofu Technology System] is upgraded! As long as you have true love with a beauty with a score of 95 or above and have children, you can unlock: hypersonic engine, Nantianmen Project, aerospace mothership... Su Chen: Since you want it, then I'll give it to you! With a backhand, he sent the parameters of the [Perfect Version] to the dense dragon country, and handed the parameters of the [Inferior Version] to Sakura. Ministry of Science and Technology of Longguo: This is a national hero! The file is classified as top secret, and he is appointed director of the department. Even if there is a war, we must keep him safe! Senior officials of Sakura Kingdom: This is the hope for the rise of the empire! Quickly, send all the wealthy daughters, top actresses, and kendo geniuses to the University of Tokyo, and make sure that Su-san's bloodline is left behind! So, amidst the scolding of "traitor", Su Chen started a crazy "scientific research" road in the hinterland of the enemy country. "Susan, why do photolithography machines always explode when they are built?" Su Chen hugged the chaebol eldest lady and said calmly: "That's because I don't have enough love. I'll send you some beauties with 95 points!" When the Dragon Kingdom's fighter planes swept across the world, the Sakura Kingdom was shocked to realize that the "Father of Science and Technology" worshiped by the whole country was actually the Dragon Kingdom's deepest undercover!
