834 Brother And Sister!

"Huh? No need?" The guard was dumbstruck. Before he could react, he felt a sharp pain in his neck. He then fell to the ground unconscious.

"Hey, what happened to you?" Luo Chao shook the guard's arms and exclaimed in surprise with a pale face. She seemed shocked by the sudden situation.

Another guard inside the sentry box saw this sudden change and immediately rushed over. He asked anxiously, "What happened?"

Luo Chao had tears in her eyes. "I, I don't know too."

The guard took the unconscious guard over. Before he could examine the guard, he felt a sharp pain in his neck too. He then fainted to the ground next to the unconscious guard.

Luo Chao slowly positioned the two guards' back against each other. After that, she waved her right hand in the air.

The hundred mecha operators hiding in the corner suddenly rushed out and charged into 001 camp.
