Kyushu Military God (Zun of Beidou)

The Qin family has three siblings. Both of their parents died when they were young, and they grew up in an orphanage until they were separated twelve years ago, and their life trajectories were disrupted. "Ziye, my sister is gone. Don't take revenge for me. The Xing family covers the sky with only one hand. You can't fight them." "Second brother, I miss you so much! They all despise me for being a live-in son-in-law and call me a waste. My life is so depressed..." Me, Qin Ziye! The overlord of the overseas world, the leader of the Kyushu Military Academy, hereby swears an oath! Anyone who kills my eldest sister or insults my younger brother will have your entire clan slaughtered! !
