Wallfacer's harem

The Tri-Solarain invasion fleet is headed towards earth. They're more advanced then humans in every feild of science. Their sophons (sub atomic spy robots) are already here, sabotaging our high energy physics so that we can not close the science gap as well as reporting on us to the trisolarians . The one area in which they are inferior to humans is trickery and deception. So humanity created the Wall Facers, who had the authority to demand any resources they needed to implement strategems that could catch the Tri-solarians by suprise, without giving any sort of explanation as to why lest the sophons hear. ......... The opening phase of your plan was to order sexually attractive experts on science and engineering to move into your compound, and join you in whatever activities you dream up. Hopefully the Trisolarians won't be able to figure out which activities are just romantic games and which are planning or implementing your master strategem too late!
