Gao Yang was dead set on getting rid of the wound on his neck, not because he was vain.
As a mercenary, Gao Yang was very reluctant to have a conspicuous, characteristic scar that could allow anyone to recognize him at a glance. Therefore, for injuries on exposed areas such as the face or neck, it's best to treat them early and avoid leaving scars if possible.
There weren't many plastic surgery clinics in Dubai, but there were some, and the ones that existed were top-of-the-line. Gao Yang stayed behind and found a private clinic to treat the wound on his neck before it had fully healed and scarred.
Apart from Bruce and Lucica, everyone else had left Dubai. Bruce, who needed a longer time to recover, after staying in Dubai for another four or five days and being able to move, finally couldn't stand staying any longer. He strongly requested to leave with Gao Yang.
In Dubai, even the airports and major airlines are full of human touches, of course, that's for the rich.
