Tan Rou left Wang Si's house with the nursing robot. When she went downstairs, she met Zhuang Liu at the stairwell, who was about to go upstairs. She was a little surprised. "Why are you here?"
Zhuang Liu heaved a sigh of relief when he saw Tan Rou walk down safely. "I'm here to look for you. I'm sorry, I didn't investigate properly when I was looking for volunteers and included people like Wang Si."
Tan Rou smiled. "You don't have to apologize. I have to thank you. If you hadn't invited Wang Si in, I wouldn't have had the chance to get the experimental data of robots protecting humans. This experiment made me realize many shortcomings, but it also provided me with a direction for future improvements, so I'm still very happy."
