"Counter-espionage and political protection by the Security Department," Mu Qianxun added.
"What does counter-espionage have to do with Si Mo?" Xia Yiwan didn't understand.
Si Mo was the head of the Anti-Terrorism Organization, not a spy.
"Tang Jin, call your friends back home right away to ask about it; we'll talk more once we return," Mu Qianxun said as he started the car.
Tang Jin responded and immediately picked up the phone to call Si Liya.
"Xiaojin, why are you suddenly calling?" Si Liya asked.
"Mom, is there anything wrong at home?" Tang Jin inquired.
"Nothing's wrong," Si Liya's voice sounded quite normal.
"What about my brother? Is he all right?" Tang Jin asked.
Si Liya paused. "I don't know about your brother; I haven't seen him these past few days."
Tang Jin nodded at Xia Yiwan and shook his head, then spoke a few more words to his mother before hanging up.
"Gu Chen, call Gu Chen," Xia Yiwan said.
