A slap

What did he just say? Yu Dong couldn't believe that all the effort she put into saving Fang Chi would be repaid like this. She stared at the young mer, still leaning against Chen Mi, and suddenly felt an itch in her hand. How can someone be so careless with their life? Her heart lit up with raging fire at the thought of how many officers with children and families lost their lives while performing their duties. They died with glory but - what about their families? 

However, their actions could still be justified even if the grief of their families could not. But for Fang Chi's situation, there was nothing, absolutely no explanation, that might justify or much less even explain what he just tried to do. Even after doing such a ridiculous act and watching his grandmother cry, he was still going on with this 'why did you save me?' line of thought. Was he seriously asking that? Can't he see his poor grandmother's tears?
