At this time, the soldiers of the three legions on the eastern defense line had completed their integration. The drones took the lead, and armored vehicles equipped with the most complete weapons and equipment carried out a sweep of the zombies encountered along the way.

The heavy firepower troops launched fire coverage on the gathered zombie group. Heavy machine guns, grenade launchers, and rocket launchers were firing crazily like they were free. Bang, bang, bang, biu~bang!

The elite special forces targeted the mutant zombies. The hideous-looking weird zombies were headlocked by sniper rifles as soon as they showed their heads. There were also drones carrying explosives tracking and bombing them until they were confirmed dead.

When an area is cleared of zombies, more armored infantrymen with assault rifles will build a defense line on the spot, waiting for follow-up troops to advance.

The few trucks carrying important supplies and the wounded walked at the front of the escort team, followed by the survivors who lined up in front. Each group of survivors in front had law enforcement teams guarding on both sides.

The long dragon-like retreating team retreated in an orderly manner without any disturbance.

When the last group of retreating survivors looked behind them, Lin Ruolan and a group of officers were standing not far away, watching them gradually leave.

The most prestigious leader of the safe zone followed the legionnaires who were covering the retreat and served as the rear guard for everyone else. This was the reason why the survivors did not cause unrest because of the order of retreat.

Lin Ruolan stood on the high platform of the east gate, allowing herself to overlook a wider view.

Watching the last group of survivors leave, she nodded to the officer beside her.

A signal flare shot high into the sky, signaling the soldiers covering the retreat to prepare to leave.

Following several deafening explosions, the explosives previously placed on the other three lines of defense were detonated. The aftermath of the explosion caused several buildings in the distance to collapse.

Ten minutes later, dozens of jeeps gathered from the north and south of the safe zone, and several officers got out and saluted.

"Report to the commander, everyone is proceeding as planned."

The old officer nodded and said, "You have worked hard. Prepare to evacuate."

"yes!"

"Wait!" Lin Ruolan's words made everyone stop. She pointed to the sky in the distance with a serious look, "The fog is getting thicker."

To the west of the safe zone, the drifting fog suddenly became thicker. It turned out to be just a slight visual difference and nothing unusual could be seen.

But the next moment, the quiet fog suddenly surged, covering half of the safe zone in the blink of an eye, and approaching the people in the east.

"Everyone, alert!"

With a sir, the fully armed soldiers in the jeep immediately got out and stared at the spreading fog with guns.

"Minister Lin, sir, you go first!"

Lin Ruolan shook her head. "It's obviously coming for us. If we don't deal with it, it will soon catch up with the retreating team."

The drone was controlled to fly into the depths of the fog. After a moment, a noise was heard and the drone fell to the ground, turning into a pile of scrap metal.

In the mist, a human-shaped misty figure slowly emerged and stood in the air.

Facing the countless guns pointed at him, Ernu showed an arrogant expression, but unfortunately it was hidden in the fog and no one cared.

"Natives, I'm just going to rest for a while, and you actually want to escape. That's not right."

"You are all sacrifices to the mist. None of you will escape today."

The soldiers ignored the Mist Man's mumbling in a foreign language. With a click of a button, the trigger was pulled and gunshots rang out.

Boom! Boom!
