"Yes, they are sisters."

The bait is salty and the hook is straight, come and bite.

Professor Feng took a few steps forward, then retreated to the safe zone at the secretary's reminder. He suppressed his inner feelings and asked as calmly as possible, "Where did Gu Changge go? Is she okay now?"

"My sister is not in this world. She is living well in another place. You don't have to worry about her." Gu Huaiwei pretended to be mysterious, sighed, and looked very embarrassed. "As for where my sister went, I can't explain it to you, because even if I told you, you wouldn't understand."

True and false, real and fake, making it difficult for the other party to figure it out.

"I understand." Professor Feng adjusted his gold-rimmed glasses.

"What?"

What do you understand? Gu Huaiwei was just talking nonsense.

Professor Feng's expression was gloomy, with a shadow covering the bottom of his eyes and the sides of his nose. He stared at Gu Huaiwei with increasingly eager eyes.

"You two go down first."

Professor Feng seemed to have made a decision in his mind. He waved his hand and asked Qian Duoduo and the secretary to leave first.

"yes."

After everyone left, Professor Feng pushed open the door of the glass laboratory.

The leather boots stepped on the marble floor, approaching step by step, clear and powerful, as if stepping on Gu Huaiwei's heart.

What is this guy doing here?

Gu Huaiwei cautiously touched the jade bracelet.

"Don't be nervous." Professor Feng leaned close to Gu Huaiwei, his breathing so close that she could hear it. His voice was as soft as a breeze in her ear. "I understand because I've also been a plane operator."
