At midnight, a few guards were seriously watching the entrance as usual. At that moment, a ball of black smoke approached swiftly from a distance. There was a rough, cold and manic smile, and the black smoke moved at an astonishing speed as it darted into the old Qi family residence.
The guards at the old family residence were all elites who had retired from the special forces, and were very capable. One of them rubbed his eyes and felt that something wasn't right. He couldn't help but ask the person next to him, "Old Zhang, did you see anything just now?"
The guard called Old Zhang also sensed something wasn't right; it felt like he had heard someone laughing. Old Zhang's heart trembled and he felt that he was probably thinking too much. How could there be anybody around at this time? He shouldn't scare himself. Old Zhang hurriedly said, "What is there to see? There's not even a shadow!"
