Zi Yi asked Lu Jingye as soon as they walked out of the room, "Where's that Gu Master? I'll go and meet with him."
Lu Jingye looked at her taut expression and raised his hand to hold hers. "This person is a little strange, so wear some protective clothes before you meet him."
Zi Yi responded with a nod.
The three of them walked to one of the labs. The Gu Master who had been secretly following Zhang Hanyu was locked inside.
Zi Yi did not immediately open the door to the lab. Instead, she knocked on the door several times.
Shortly afterwards, the door changed into a one-way mirror where she was able to see the inside of the room from the outside.
The Gu Master had his hands and legs tied as he leaned against the wall in a corner.
