Old Master Chen's face changed when he heard these words.
He personally leaned on his cane and came to the door.
When Gu Shengyin was in the hotel alone with his puppet, he would subconsciously reveal a trace of his true nature.
However, in front of outsiders, he maintained his noble and cold persona flawlessly.
Old Master Chen scrutinized Gu Shengyin, feeling a bit doubtful in his heart. After all, with that appearance, Gu Shengyin did not seem like a good person at all.
But what kind of person was he?
No matter what he was thinking inside, not a trace of it would show on the surface.
Moreover, Old Master Chen had come into contact with quite a few people like Gu Shengyin, and he knew that some masters liked to pursue "unique" styles, so he quickly recovered.
He politely said, "I heard that the master is here for my son? May I ask how I should address you?"
