A Blind Man

Chris put down the document in his hand when he heard the voice.

He got up and walked briskly forward. Looking into Merry's restless eyes, he furrowed his brows and said reassuringly, "What's wrong? Don't worry, tell me the details."

Merry rushed to him, picked up her phone, and explained in a panic. "I wanted to call mom, but the voice said the number has been changed, it's as if the number never existed! I called her last night, why is it suddenly like this?!"

Chris narrowed his eyes. He then hugged the little girl and patted her on the back. "Are you sure you didn't make the wrong call?"

The little girl shook her head anxiously. "I have called many times, the result is still the same."

After hearing the voice, Chris tried to calmly think about it. He then turned to the table and handed Merry his cell phone. "Try again with mine."
