The Great Demon knew the answer in his heart; otherwise, he wouldn't have gone through so much trouble to find Su Mu.
The portal can no longer be opened, which means Su Mu must have learned some news.
He was very certain of this point.
Seeing Su Mu wasn't cooperating, the Great Demon turned and prepared to leave.
"Once I leave this time, I will never appear in your lifetime again."
After taking three steps, the Great Demon heard Su Mu's voice.
"Wait a moment."
The Great Demon didn't stop his steps.
"Wait, swear first, and I will trust you."
The Great Demon completely disregarded these words and continued moving forward.
"I know another way to open the portal."
The Great Demon's footsteps paused, and he slowly turned his head, his heart tremendously shocked—there's another way to open the portal?
"Swear first," Su Mu insisted.
The Great Demon thought for a moment, decisively extended his hand, and tapped his chest.
