In the blink of an eye, night had fallen outside.
The clock on the wall had reached the number nine.
Jiang Yifeng rubbed his sore back and looked at Shen Yanhe, who was still calmly and methodically processing the medicinal materials, a look of admiration appearing on his face.
After dealing with medicinal materials all day, he felt dizzy and had to walk around from time to time.
But since Miss Shen began working, she had maintained the same position without change.
The amount of medicinal materials she had processed was twice as much as he had.
Jiang Yifeng sighed inwardly and looked at Shen Yanhe, asking, "Miss Shen, it's already nine o'clock. Do you need me to take you back?"
The laboratory was established in the suburbs, a distance away from the city center. It wasn't safe for a young girl to go back alone.
