Amidst the billowing smoke, the helicopter took off.

Everyone was filled with a heavy heart, tears streaming down their faces. The brutality of the Siege City was far beyond anyone's imagination.

The horror of the Toxic Corpses was etched deeply into their minds for the first time.

Zhou Zheng stared expressionlessly at the receding smoke, feeling a turmoil inside. He wanted to cry but couldn't make a sound, so he let the tears silently stream down his face. Memories from the past month flashed through his mind like a movie, scene by scene.
