Siheyuan: It's All Underworld Technology. Are You Going to Fight Me?

Li Ru traveled to a courtyard house and became an ordinary resident, and at the same time awakened the blind box system. "The blind box extraction was successful!" "Acquire a physical strengthening serum, a graphene heating stove, a solar panel, a micro eavesdropping suit, detailed drawings of machine tools over the years, and a radio wave search device..." Haha, I, Li Ru, am a research intern at the Academy of Dragon Science. It seems reasonable to own these underworld technology products! … You slapped Jia Zhang and kicked the God of War, Silly Pillar, because you were injected with the serum? If you don't burn coal in winter, are you going to rely on this heating stove to keep out the cold? We can hardly afford to pay the electricity bill. How can you still use this black board to generate electricity? Where did you hear what the young couple said under the covers? You mean, you found the enemy agent just by relying on this little box?
