Si Kongchen's car was marked to pass the security, so he drove all the way into the area. On each side of the gate was a ten-meter-tall sentry post, guarded by soldiers. As Si Kongchen showed up, the soldiers in the sentry posts and by the gate all saluted him quietly.
Si Kongchen walked straight through the gate, into a metal building which took up about three-hundred meters squared area. In the building was an entrance to the underground space. Si Kongchen walked in and took the stairs down.
A door was located about ten meters deep underground, behind which was an elevator. Si Kongchen walked into the elevator, and then it moved downward for three minutes. As the elevator door opened, what Si Kongchen saw was an experimental base. The research projects being carried there weren't the same as the ones in the secret underground lab in Huaxia Base.
