Chen Nan said, "What do you mean?" Seeing Chen Nan lose her temper, the other party apologized and said, "I'm sorry, sir. This is a rule." It was not until this moment that Zhou Zikai remembered. After saying a few words to Chen Nan's ear, he nodded and thanked himself that he had brought the card. He then handed the invitation card to the man in black and said, "Can we enter now?" When the black-clad man saw the gold-plated invitation card on the outside, he suddenly became respectful. He handed the invitation card to Chen Nan with both hands and said to him, "I'm sorry, sir. It's inconvenient for me to give you this card." Then he slightly bent down. Seeing this, Chen Nan smiled and didn't make a fuss about it. Zhou Zikai, who also handed over the invitation card, entered the arena.
