On the other side, Wang Yu and Fearless led Javier to the damaged wall.
Perhaps it was because Javier was a professional in this field, the moment he glanced at the wall, he was able to discern what the cause of the phenomenon was. He turned to Wang Yu and said with certainty, "The damage done to the structure of the wall was mainly due to an item known as fossil powder."
"Fossil powder? What's that?" Wang Yu asked curiously.
Since this was an investigation quest, they naturally needed to understand the entire circumstances leading to it.
Javier replied, "It is a type of mineral that can only be extracted from the seas, and could break apart the stone structure within stones. However, this item is extremely rare and only the pirates from Harbor City possess it."
"Harbor City?"
"Pirates?"
The moment they heard what Javier said, both Wang Yu and Fearless came to a sudden realisation.
