Xia Jinyuan spent two months recuperating in Myanmar. It was not until the wound on his chest had completely healed that Luke told Cobra that they could return to Molaban. After coming back, Luke had also received the heavy responsibility handed to him by Cobra. However, he was slightly worse off than Xia Jinyuan.
Luke didn't have Xia Jinyuan's courage to make a desperate move. Hence, even though he had been hiding for almost six years, he didn't come into contact with Cobra's secrets. However, with Xia Jinyuan's invisible help, he made great progress.
Now, the situation was getting clearer. Even if Luke only provided a few clues from Xia Jinyuan, it was enough for Russia to create a gap in the impenetrable wall. This gap would become the exit for Luke to return to Russia and Xia Jinyuan to return to China in advance.
