Don't think that Anton and his team's display of loyalty seems a bit exaggerated, or deliberately "acting." In reality, this truly reflects their innermost thoughts!
Including Anton, everyone in the Tsar's Guard has a military background. They had been discharged during the major military downsizing, experiencing quite straitened circumstances before joining the Tsar's Guard.
It can be said that it was Wang Ye who provided funds to establish the Tsar's Guard, offering them job opportunities and better living conditions.
If it were just that, they would still be grateful to Wang Ye but wouldn't necessarily express their willingness to sacrifice their lives for him in person. Of course, if Wang Ye were indeed in danger, they would probably still be willing to lay down their lives.
Today, Wang Ye suddenly announced that he would transfer them all to the National Guard, which meant something significant to these former soldiers, and each one of them was well aware of what it implied.
