I Own Black Technology and Was Exposed by My Sister's Live Broadcast

After Chen Ziyu traveled to the parallel world, he had a black technology system. After several years of working experience in a large factory, he decided to make the robot by himself! But who would have thought that during the holidays, relatives would besiege me for not working, and even my sister who does live broadcasts would be criticized. At this moment, the robot "Xiao Xiaoming" made by Chen Ziyu made his debut! One-handed Thomas, handstand in the air, are all simple, and can even be used for cooking, laundry, and taking care of people's normal daily life. And all this happened to be exposed by his sister's live broadcast. Everyone thought this was the most powerful thing. As a result, my sister was exposed one after another, which surprised everyone! Super drones spray pesticides? Robot dog spreading seeds? Unmanned ships making nests? Isn't this an anti-aircraft cannon to kill mosquitoes?
