In the Rex Detective Agency, Rex was sitting in front of his computer and typing quickly on the keyboard.
Hei Ling came to the office as usual, and as soon as he entered the door, he saw Rex with a serious look on his face.
"Mr. Rex, what are you doing?" Hei Ling walked over and asked in confusion as he watched Rex typing in front of the computer.
"Hmm? Xiaohei, are you here? It's nothing, just a promotional advertisement."
"Can I help you with anything?"
Rex pointed to the introduction on the screen which should be no more than 400 words and said, "Why don't you write it for me?"
Hei Ling was not good at this at all, but after Rex called him, he had no choice but to try to write it down.
"Rex Detective Agency can solve any problem for you. Please be sure to watch this page. There is an omnipotent detective and disciples who can "really" solve any problem for you.
"No, no, no, no!!!!" Rex saw the advertisement that strongly opposed Black Spirit.
"But, Master, how else are we going to advertise?"
Rex looked at the number of words on the screen and shouted in surprise, "No! There are still 35 words left to use!" Then Rex turned back and ordered, "Hurry, Blackie! Find a way to do something!"
"Ah!"
