These herbs were highly potent; the smoke they produced when burned was extremely pungent.
Ouyang Shu bent over the basin, his face directly above it, feeling very uncomfortable.
"A-choo!"
Accompanied by Ouyang Shu's sneeze, an extremely tiny insect was expelled, flying onto the table and struggling a few times before becoming motionless.
Song Yun was very curious when he saw this; he hadn't expected that Gu techniques would have been passed down to modern times, let alone who had cast it!
"Song Yun, what is this?"
Ouyang Rong's face was gloomy as he stared at the insect on the table, hardly daring to imagine that his father's body contained such a thing!
"A Gu insect."
Song Yun picked up the insect and casually tossed it into the basin, where the flames surged up as if the insect contained a powerful energy.
"Old master, move your body around a bit."
