Four Symbols Card and the Lonely Zombie

Matthew smiled and ignored the sarcasm in his words.

The two of them slowly approached.

Then, under Little Bear's curious gaze, the two sides quickly completed the transaction.

Matthew handed over two pieces of Idon grass and received a crystal key, a piece of parchment with a set of special coordinates, and a mystical card.

The crystal key was said to be the key to opening the Secret Chamber of Life.

The coordinates on the parchment were extremely complicated.

Matthew quickly interpreted it.

He suddenly realized that the coordinates pointed to the mass graves in the Crow Pavilion Demon Domain!

"Viscount Fan's territory?"

Matthew was extremely surprised.

As for the card, it was described in the data column.
