Professor Tang saw that Eldest Master Sun's expression wasn't right and subconsciously looked at him. He quickly reminded him, "Oxygen no longer works on Old Master Sun."
Eldest Master Sun's body trembled. After taking a deep look at Chu Luo, he quickly opened the door and shouted at the person outside, "Go and find a black dog immediately. The sooner, the better!"
There was a response from outside the door, followed by the sound of running feet.
Chu Luo quickly took out a few silver needles and sealed a few of Old Master Sun's major acupoints. She said to Eldest Master Sun, "All of you, go out later. It's best if all of you leave this house… If anyone's birthday is close to Old Master Sun's, you can leave one such person to keep guard outside the room. Remember, don't let anyone enter your house."
Eldest Master Sun opened his mouth to say something, but in the end, he nodded at her without saying anything.
