Liu Qian and Chai Ren chatted for about ten minutes. When it was almost time, they rose to check in their luggage and go through security. In no time, they boarded their flight. Both being affluent, they sat in first class.
The 'professional etiquette' of the fighter sparked a competitive spirit in Chai Ren's two bodyguards. They tried to maintain the same level of alertness as the fighter, however, it was impossible for a human being to be constantly aware of everything around them for a prolonged period of time. Even the special forces who are used to such rigor wouldn't last long.
As predicted, they were completely exhausted in just one hour. Their bodies were fine, it was their spirits that were drained.
