Staying at Home for Five Years, the House Full of Black Technology Was Exposed by My Sister

I wanted to use the live broadcast to reveal the ugly appearance of the room of my brother who has been staying at home for five years. However, Du Tiantian and all the netizens who opened the door were stunned by the black technology in the room. AI? Nanotechnology? Virtual projection? Are you telling me that someone who has stayed at home for five years can research this? This novel and its characters are purely fictitious.
