There were a few servants busying about in the courtyard. Long Chi narrowed his eyes and suddenly tossed the medicinal ball.
Beitang Rui was still confused as to what Long Chi was trying to do when he suddenly heard a loud, explosive bang.
The next thing he knew, thick smoke covered the whole area and he did not even have time to react before he heard Long Chi shout, "Cover your mouth and nose, Prince Rui. We might be far away, but we will fall unconscious if the smoke drifts over and gets inhaled."
Right as Long Chi said this, Beitang Rui saw a few of his servants not far away fall heavily to the ground.
"What's going on?" Shocked, he was about to go over to them to see what was happening when Long Chi stopped him. Long Chi covered his mouth and nose with a handkerchief while explaining, "They have fallen unconscious from inhaling the coma-inducing smoke, but their lives aren't in danger."
