What logic?

#1

After entering the Ancient City, why was it that Huangfu Changtian was able to send a message to others to deceive them, yet Chen Xi’s group didn’t send a message to look for someone? Were they stupid? Or is there a trap for the author’s logical thinking? After entering the city, instead of contacting your own people and saving your own wife, you go first to the Battlefield Monument to test your combat strength? Was his brain filled with water?
