Fang Wumu's piglet bag was a gift from the old man himself, so of course, he recognized it at a glance.
The old man's heart skipped a beat.
Not only was he worried about his adopted son, but he was also afraid that if his son fell into Yu Lie's hands, their secret dealings might be exposed.
Fortunately, the old man still had some trust in his adopted son.
He believed Fang Wumu wouldn't recklessly spill the beans, so he managed to keep his composure.
Then, Yu Lie spoke again:
"Hall Master Fang, if you keep stalling, you might end up burying your own son!"
As he spoke, Yu Lie opened the piglet bag and pulled out a human head, showing it to the old man to prove he wasn't bluffing.
This made the old man both relieved and anxious.
Relieved because Yu Lie was only threatening Fang Wumu's life, meaning he likely didn't know about their shady dealings.
Anxious because his son's life was truly in Yu Lie's hands.
