The security guards who had not yet gotten out of the elevator were knocked down by Zhao Yu. Those who had been fooled by Zhao Yu screamed, "Catch him! Don't let him run away!" Zhao Yu couldn't get in the elevator. He turned and ran. This eighth-floor secret area was not large compared to the rest of the night club. Zhao Yu easily arrived at the stairwell closest to him.
Because of the importance of the area, the door of the stairwell was locked. Zhao Yu wrenched the door open and rushed into the stairwell. He found several mops in the stairwell and put them against the door to keep it closed. The people who chased after Zhao Yu banged on the door but couldn't push it open.
