"Gang leader! Today's blood essence has been delivered!"

A disciple of the Iron Corpse Gang knelt at the door of the underground palace, respectfully placed several jade bottles containing blood essence at the door, reported the situation, and then retreated, closing the formation at the same time.

Xu Mu is stuck here.

The invisibility spell has a limited time and may be exposed at any time.

However, there was not much panic on Xu Mu's face. He squatted in the corner and waited patiently.

After a while, with a creak, the heavy stone door slowly opened, and a thin figure covered in black robes walked out, skillfully picked up the jade bottle on the ground, and prepared to return.

Xu Mu's eyes flashed, knowing that this might be his only chance. The Thunder Sword suddenly appeared in his hand, and his whole body suddenly rose up, turning into a golden thunder, and slashed it with one sword.

Poof!

The black robe had no time to react before he was struck by the sword light and cut into two pieces, revealing the shriveled body inside.

"Who!!!"

A roar sounded from behind the stone door.
Chapter completed!
