Gu Chen was unconscious, so Song Fan had to handle everything herself. She hacked into all the surveillance around the airport and, with Lan Yue, cracked the facial recognition system. After several hours, she finally found Song Kai's trail. If Gu Chen were awake, he wouldn't have allowed her to do this, but with Song Kai in trouble, she couldn't wait any longer. Moreover, she had to get the Tango Fruit, or Gu Chen wouldn't last much longer.
"Boss, I found the person who kidnapped Song Kai. He's a doctor. Could he be one of Peter's men?" Lan Yue asked, her anxiety evident.
She had also dug deeper into Xia Yu's background, discovering that the real Xia Yu had died in a car accident abroad long ago. The current Xia Yu was just an impostor, with no other traceable information.
Song Fan had also uncovered this information. She continued to track Xia Yu, but he was highly aware of counter-surveillance, leaving very few clues.
