Zombies Are Not Moving

The pilot had no intention of landing the helicopter. He just kept circling in the sky. 

Another man on the helicopter slid down a ladder. After checking everything, he instructed Li Ran, "You have one day to complete the mission. We will come and pick you up tomorrow around this time. Send a signal if you're at a different location. It's the only way to communicate."

Then, the man handed Li Ran a firework and lighter.

Li Ran nodded. 

"We will make sure to keep an eye out, so there's nothing to fret."

Everything seemed to be in order.

However, when the man glanced at Li Ran's stomach, he hesitated for a moment before asking awkwardly, "Are you pregnant?"

"Yes."

The man retracted the ladder and said, "There's no need for the ladder. We'll just land as low as possible for you to get off."

"What if she falls…" 

Before the pilot could finish his sentence, the man changed the topic.
