Thor did not walk toward Xue Xi. Instead, he walked toward Xie Yingying and said, "Student, what's your name?"
Xie Yingying: "?"
Stunned, she replied in English, "Xie Yingying."
Thor nodded. "Then give me your contact details. Do you have a phone number?"
Xie Yingying: "!!!!"
After she exchanged contact details with Thor in a daze, she saw that he smiled and greeted Xue Xi before leaving.
Why did he ask for Xie Yingying's contact number? It was because Thor was afraid that Xue Xi would not pick up the call. He was tired due to waiting for her.
As for those redheads, Thor did not know where they came from. Only Xie Yingying was from the Mathematical Olympiad.
Thor decided that if the Goddess of Wisdom did not answer the call, he would harass Xie Yingying. Moreover, he planned to conquer Xie Yingying first and get her to help persuade Xue Xi.
Xie Yingying also got to know Thor.
