"We've been attacked!"
As the four shadows appeared on the 19th floor, the guard standing outside of the building charged at the four of them immediately. An immortal-level leader of the guards ran as quickly as he could to the entrance, attempting to ring the alarm but he was blocked by a person in black robes who teleported himself right before the guard leader.
"I'm sorry, this road is closed!" A voice came from a voice-modulating shell.
The leader of the guards attacked with his sword without thinking twice and a black streak slashed in the air. However, the black-robed person grabbed the black streak and it disappeared. The immortal-level head guard's neck was broken as well. By the time the head guard fell to the ground, the tens of the other guards were dead.
"The guards at the Union Government are useless," a cold voice said softly.
